FIELD: transport engineering; machine-tool industry.

SUBSTANCE: mounted on coaxial drive shaft 5 and driven shaft 6 are drive bevel gear wheel 3 and driven bevel gear 4, respectively which are thrown into engagement with main satellites 7 and 8 provided with sturdy rims and mounted for free rotation on shaft 2 of flywheel 12. Additional satellite secured on one end of shaft 2 is thrown into engagement with taper sun wheel 10 secured in transmission body 9.

The invention relates to mechanical engineering and can be used in transportation, mainly in the automotive industry, as well as in machine tools.

Known inertial coupling, leading coupling which is made in the form of a drive shaft and drove in the shape of a frame carrying bearings radial shafts with satellite and inertial loads. Not driven shaft has a Central conical wheel that is part of the engagement with the satellites. The Central wheel is made in the form of the rim, inside of which is placed a frame with flywheels, given the mass of both wheels is equal to and concentrated at the point of intersection of the axes of the clutch and flywheel (see RF patent 2047017, IPC 6 F 16 D 43/14, 27.10.95).

The disadvantage of this inertial coupling is the lack of external support during transmission of torque, which excludes the possibility of its change depending on the load on the driven shaft.

The closest set of features technical solution to the claimed invention is an automatic continuously variable mechanical transmission that contains the master and slave Central bevel gear, put into engagement with the conical main satellites placed on radial axes drove. Posted by ibid conical additional satellites put into engagement with the to the technical Central stationary support wheel. Drove placed between the Central master and the slave wheels with the possibility of free rotation around the axis of the transmission on the master or the slave shaft. The primary and secondary satellites placed on radial axes were taken with independently from each other rotation (see RF patent 2178107, IPC 7 F 16 N 33/14, 3/74, 10.01.2002. Bull. No. 1).

The disadvantage of this automatic continuously variable mechanical transmission is hosted massive satellites, performing the role of the flywheel or inertial loads, away from the axis of the transmission, which leads to large centrifugal forces during their rotation around the axis of the transmission and creates the need to strengthen all elements of the transmission with the appropriate complexity of the device and an increase in their weight.

The present invention provides the achievement of the technical result, which is to reduce the dynamic loads on the transmission elements with capability of reducing the strength of these elements, respectively, and their weights.

This technical result is achieved by the fact that the automatic continuously variable mechanical transmission contains measured with the possibility of rotation around the axis of the transmission carrier bearing diametrically relative to the axis of the transmission rod, placed on different sides were taken and diametrically tapered rod master and slave wheel, fixed respectively on the master to the slave shafts placed with the possibility of free rotation on the diametrically tapered rod main satellites entered into engagement with said leading and trailing wheels, rigidly connected with the housing of the transmission bevel gear of the Central wheel. According to the invention the carrier is made in the form of framework housing, inside of which is placed an inertial load in the form of a flywheel mounted on diametrically terminal, which is the shaft of the flywheel at one end of the aforementioned shaft flywheel fixed additional satellite entered into engagement with the supporting wheel, the shaft of the flywheel is connected with the planet carrier with the possibility of free rotation.

The centre of mass of the flywheel is aligned with the axis line of transmission.

The main satellites are made with massive rims.

Axis line of the transmission and the longitudinal line of the flywheel shaft intersect at a Central point, combined with the mentioned lines.

As a special case of execution, the main satellites made in the form of rigidly coaxially interconnected into a single block of two conical toothed wheels, internal and external relative to the axis of the transmission, one of which is engaged with the sprocket wheel and the other with a driven wheel, and these siteplease pair of wheels are different sizes of paradatec is s relationship.

As a special case of execution, each of the major satellites made in the form of one gear and is in mesh simultaneously with the master and the slave wheels, forming with each pair of wheels having the same largest gear ratio.

The transmission is equipped with placed on the line of the axis of the transmission mechanism of a free motion, the leading element of which is connected with the planet carrier or the shaft of the flywheel and a driven element fixed in the housing and prevents rotation of the carrier together with the flywheel and the shaft around the axis line of transmission in the direction of rotation of the driven shaft.

On the shaft of the flywheel on the opposite side from the additional satellite fixed balanced relatively to the axis of transmission of the load.

The following drawing gives a General view of an automatic mechanical stepless transmission (hereinafter - transfer), showing its elements and distinguishing features that characterize the invention.

The transmission contains placed rotatably around the axis line o-O of the transmission carrier 1 carrying diametrically relative to the axis of the transmission rod 2 placed on opposite sides of the carrier and diametrically rod bevel gear leading 3 and slave 4 wheel, mounted respectively on the master 5 and driven shafts 6, posted with free rotations is to diametrically terminal 2 conical main satellites 7, 8, introduced in engagement with said leading and trailing wheels, rigidly connected to the housing 9 of the transmission bevel gear Central support wheel 10. Drove 1 made in the form of framework housing, inside of which is placed an inertial load in the form of a flywheel 11 mounted on diametrically terminal 2, which is the shaft of the flywheel. At one end of the aforementioned shaft and flywheel fixed additional satellite 12, is introduced into engagement with the supporting wheel 10. The shaft 2 of the flywheel is connected with the planet carrier 1 with the possibility of free rotation.

The centre of mass of the flywheel 11 is aligned with the axis line o-O of the transfer.

The main satellites 7, 8 are made with massive rims.

Axis line o-O of the transfer and the longitudinal line O1-O1the shaft 2 of the flywheel intersect at the center point O1combined with the mentioned lines.

As a special case of execution, the main satellites made in the form of rigidly coaxially interconnected into a single block of two conical toothed wheels 7 internal and external 8 relative to the axis line o-O of the transfer. One of these wheels is engaged with the sprocket wheel 3, and the other driven wheel 4, and these siteplease pair of wheels have equal ratio.

As a special case of execution, each of the major satellites 7, 8 are in the form of eding the gear and is in mesh simultaneously with the leading 3 and slave 4 wheels, forming each one of the pair of wheels having the same largest gear ratio.

The transmission is equipped located on the axis line o-O of the transmission mechanism freewheel 13, the leading element of which is connected with the planet carrier 1 or the shaft 2 of the flywheel and a driven element fixed in the housing 9 of the transmission and prevents the rotation of the carrier together with the flywheel 11 and its shaft around the axis line o-O of the transfer in the direction of rotation of the driven shaft 6.

On the shaft 2 of the flywheel on the opposite side from the additional satellite 12 is fixed balancing it relative to the axis line o-O of the transfer of the load 14.

Automatic continuously variable mechanical transmission works as follows.

During the rotation of the driving shaft 5 and the stationary driven shaft 6 and the driven wheel 4 in connection with the attached to the follower shaft load or the beginning of the rotation from a stationary position mounted on a drive shaft 5 of the drive wheel 3 causes the rotation around the shaft 2 of the flywheel 11 is interlocked between main satellites 7, 8. The external main satellite 8 rolls on his mesh fixed to the slave wheel 4 and engages carrier 1 together with placed in it by the flywheel 11 and the shaft 2 in rotation around the axis line o-O of the transmission with the maximum frequency in the direction of rotation of the driving shaft 5. At the specified BP is the incarnation took 1 and a shaft 2 of a flywheel mounted on the shaft end of the flywheel additional satellite 12 is rolled over fixed in the housing 9 of the transmission fixed reference wheel 10 and rotates with the maximum frequency together with the flywheel 11 and the shaft 2 around the longitudinal line About1-O1the shaft of the flywheel.

Simultaneous rotation of the flywheel 11 and the main satellites 7, 8 around the axis line O-O of the transmission and a longitudinal line About1-O1the shaft 2 of the flywheel is equal to their rotation about the Central point O1crossing the mentioned lines.

It is known that the rotating body has a certain angular momentum, which is manifested with the observance of universal conservation law, according to which the angular momentum can be changed only under the influence of the moments of the external forces. It is also known that the angular momentum when rotating the body about a point is a vector value (see "technical dictionary" edited by academician Awesonme. PM: "Soviet encyclopedia", 1980, str/2). During the rotation of the flywheel 11 and the main satellites 7, 8 above procedure with respect to the Central point O1the vectors of their moments of momentum constantly change their direction. It is known that actions on vectors reflect the appropriate actions on vector quantities (see ibid., p.73/1, article "Vector").

The specified manifestation of the universal law of conservation from rotating relative to the Central point O1the flywheel 11 and the main satellites 7, 8 combat is there to rotation of the shaft 2 of the flywheel around the axis line O-O of the transfer. In this regard, the shaft and the flywheel is the backbone for the transmission of torque from the drive shaft 5 and the drive wheel 3 through the main satellites 7, 8 on the follower wheel 4 and the driven shaft 6. Torque from the drive shaft 5 on the driven shaft 6 is transmitted in the opposite direction.

The above rotation with a maximum frequency of the flywheel 11, and the rotation of the main satellites 7, 8 relative to the Central point O1when stationary driven shaft 6 provides the transmission driven shaft maximum value of the torque, because changing their directions of vectors of moments of momentum occurs with the maximum frequency. When this is taken into account that the main satellites 7, 8 are equipped with massive rims and rotation play the role of the flywheel (inertial loads).

With the start of rotation of the driven shaft 6 is slowing down the rotation of the additional satellite 12 and the flywheel 11 with its shaft 2 relative to the axis line O-O of the transmission and a longitudinal line O1-O1the shaft of the flywheel. This slows down the rotation of the flywheel II with respect to the Central point O1with a corresponding decrease resulting braking torque opposing the rotation of the shaft 2 of the flywheel around the axis line O-O of the transfer. However, due to the rotation of the drive and driven wheels at the opposite the one direction. speed being with them in engagement major satellites 7, 8 around a longitudinal line About1-O1the shaft of the flywheel increases, and at the same time continues the rotation of the mentioned satellites 7, 8 around the axis line O-O of the transfer and in relation to the Central point O1that provides transmission of torque and rotation from the drive shaft 5 on the driven shaft 6.

When the maximum rotational speed of the driven shaft 6 of the carrier 1 and the flywheel 11 with its shaft 2 is stationary. However, massive wheels rotating with a maximum frequency of major satellites 7, 8 have a counter-rotation of the shaft 2 of the flywheel around the axis line o-O of transmission, because all of their rotations about the axis Oh of the transmission are under these conditions rotation of the shaft 2 of the flywheel relative to the center point O1. This creates a Foundation to transfer rotation and torque from the drive shaft 5 and the drive wheel 3 follower wheel 4 and the driven shaft 6 through the rotating main satellites 7, 8.

Application of the unit main satellites 7, 8 (paragraph 5 claims) extends the limits of automatic control of the transmitted torque. When a single primary satellite (item 6 claims simplifies the transmission device while moderate reduction of possible online who tore regulating the transmitted torque.

Therefore, the proposed transmission operates in any mode of operation.

If you want to transfer torque and rotation from the driven shaft 6 on the driving shaft 5 for inhibiting production machine, the engine stops. Under the influence of torque transmitted from the rotating shaft 6, is the closure of the free wheel mechanism 13, which prevents rotation of the shaft 2 of the handwheel in one direction with the driven shaft 6, which provides the transmission of rotation from the driven shaft to the driving shaft 5 and further work on the motor shaft, forced rotation of which causes braking of the working machine. In the same way, run the engine with the use of towing the working machine.
