Gear planetary gear

 

The invention relates to the field of engineering, namely, gear mechanical transmission, and allows to increase the load capacity of the transmission. The transmission contains led-eccentric, odnovintovye satellite, fixed Central wheel with internal teeth, slow Central wheel with internal teeth, the number of which is equal to the number of teeth of the satellite. Slow Central wheel made in the form of precast squirrel wheel studs which pass through holes in the rim of the satellite. The diameter of these holes is not less than the sum of the diameter of the rod and the double eccentricity drove clowning. Technical result - increased load capacity. 2 Il.

The invention relates to mechanical engineering and can be used in all sectors of the economy, in particular in the mechanical transmission non-embedded type.

Known planetary gear non-embedded type containing carrier-eccentric, satellite, fixed Central wheel with internal teeth and slow Central wheel with internal teeth, and the number of teeth of the satellite is close to the number of teeth of the low speed wheel or equal to [1] (prototype).

key to the width of the rims because of the bias of the satellite under the action of forces of a different, operating from stationary and low-speed Central wheels, and deformation of the transmission element.

Also known planetary gear containing satellites, fixed wheel with internal teeth and slow wheel with teeth, made in the form of bridges or cantilever beams [2].

However, this transmission also has a low load capacity due to the possibility of breakage of the tooth-jumpers or tooth-beams with insufficient height of the section.

The aim of the present invention is to increase the load capacity of the transmission.

This objective is achieved in that the transmission containing carrier-eccentric, odnovintovye satellite, fixed Central wheel with internal teeth and slow Central wheel with internal teeth, the number of which is equal to the number of teeth of the satellite, low-speed Central wheel made in the form of precast squirrel wheel studs which pass through holes in the rim of the satellite, and the diameter of these holes is not less than the sum of the diameter of the rod and the double eccentricity drove eccentric.

Increase the load capacity is provided by reducing uneven distribution of load in the links of a satellite with price is. 1 shows a General view of the transmission in the context of Fig. 2 is a view along a-a in Fig. 1

Planetary gear contains led-eccentric 1; odnovintovye satellite 2; bearings satellite 3; stationary Central wheel with internal teeth 4; low-speed Central wheel with internal teeth, made in the form of precast squirrel wheel consisting of two rigidly connected with each other by means of rods 7 wheel with internal teeth 5, 6; case 8.

Number of teeth odnolistovoe satellite 2 is equal to the number of teeth of the wheel with internal teeth 5 and 6. Wheel with internal teeth 5 and 6 sliced with a large positive coefficient bias source circuit of at least two to ensure the displacement axis odnolistovoe satellite 2 relative to the axis of the wheel with internal teeth 5, 6 by the amount of eccentricity drove eccentric 1.

Odnovintovye satellite 2 is made with holes in the rim, the diameter D to prevent jamming adopted not less (see Fig. 1)

D=2e+d

where d is the diameter of the rod 7, e - eccentricity drove eccentric 1, axis equal to the distance of transmission.

Odnovintovye satellite 2 is installed on the driver-Cam 1 on bearings 3 and is engaged with the Central wheels 4, 5, 6 the three-satellite 2, away from the low-speed Central wheel 5, 6.

Satellite 2 in the process of transfer rolls on the fixed Central wheel 4, transmitting the movement connected with each other wheels 5, 6. When the satellite 2 and the wheels 5, 6 function as gear couplings, since the number of teeth of the satellite and the wheels 5, 6 are equal.

Since the ring gear stationary Central wheel 4 is located between the toothed crowns rigidly connected with each other wheels 5, 6, scheme of loading of the teeth of the satellite 2 has a symmetrical appearance, misalignment of the satellite does not occur, the load on the width of the gear rims of the wheels is distributed evenly, thereby increasing the load capacity of the transmission.
