The present invention relates to a battery energy for step switches under load.

The level of technology

Manual switches under load are used for continuous switching between different branches of the winding step transformer under load. As this switch is usually abruptly, then stepped switches are usually battery power.

This battery power is known from the publication DE-PS 19 56 369 and DE-PS 28 06 282. He is charging, that is, receives tension from his shaft, each time before actuation speed switch under load. Known battery energy is the essence of the winding carrier and skakovyh sled, between which are fixed energoakkumulyatorami spring as an energy accumulator.

In the known battery energy is provided by guide rods, which are located with the possibility of longitudinal movement independently of each winding slide and jumping the rails. At the same time guide rods form a guiding device for energy-accumulating springs, so that one energy-accumulating spring comprises respectively one guide rod.

Groovy carrier is moved linearly in the direction Skachkova the sled by means connected to the drive shaft of the eccentric, resulting in in between energoakkumulyatorami springs are tightened. As soon as winding the carrier reaches its end position, releases the lock skakovyh sled. Because they are under the influence of tension force energy-accumulating springs, then repeat linearly, but abruptly, the previous linear movement of the winding carrier. Of these publications DE-PS 19 56 369 and DE-PS 28 06 282 it is known that chaotic skakovyh sled by means of a roller, which is engaged in the groove is converted into rotational motion of the output shaft. This method of converting longitudinal motion in the rotation by the rotating roller or rocker stone has the disadvantage that at the beginning of each movement has a relatively small power reserve, and about halfway each movement force reaches its maximum, and by the end of the movement decreases again. This characteristic torque unacceptable for certain switches in which each switch is necessarily driven one after the other numerous contacts with a pre-specified sequence of operation. Continuing at the end of the switch only a small torque creates the danger that the step switch under load, not with what may be moved into its final position.

In addition, from the publication WO 02/31847 known to convert longitudinal movement skakovyh slides into rotational motion through gearing, in which the gearing is connected with the output shaft gear. For this kind of transformation of the motion is characterized by a constant increase in power, which is also unacceptable for certain sequences of switching operations. In addition, can not be modified constant torque.

Summary of the substance of the invention

The technical task of the present invention is to provide an energy storage, which allows a simple way to vary the torque on the output shaft, that is, after converting the longitudinal movement skakovyh slides into rotational movement, in particular, simple technical means to ensure the variation of the gear ratio and the creation at the end of switching high torque, providing under all conditions reliable end position and re-lock battery energy.

The problem is solved by creating a battery energy, characterized by the features disclosed in the first claim. The dependent claims relate, in particular, the variant is a modification of the invention, providing the greatest benefits.

Battery energy due to its design, consisting of two rollers in connection with the prescribed interaction of these rollers is made in a special way in the wings, providing the direction of the rollers, the sides of which they alternately engages, provides a wide range between the specific time and torque characteristics transformed with linear stepwise movement skakovyh slides into rotational motion of the output shaft with a variety of switches and the sequence of switching operations. The gear ratio of the battery power and torque and speed can be changed in the simplest way due to the distance between the two rollers.

Due to the proposed construction is provided, in particular, high torque to the end of the movement skakovyh sled, and hence the output shaft, when almost fully completed the switching speed of the switch under load.

Description of the preferred embodiment variants of the invention

Figure 1 and 2 shows the energy accumulator according to the invention, and figure 1 in the interest of better understanding not shown energoakkumulyatorami spring.

The energy accumulator according to the invention contains in connection with the output shaft (not shown) eccentric disk 1, resulting in the action of winding the carrier 3, so that it affects located at the top and bottom in the direction of winding of the slide 3 powered pads 2. In this example, run the battery energy contains three passing along the direction of motion of the winding carrier and the parallel between the guide rod 4, 5 and 6, with two of them surrounded by energy-accumulating spring 8. In the framework of the invention it is also possible a different number of guide rods and energy-accumulating springs. Clockwork rails 3 are on both ends of the linear bearings 7, which cover, respectively, one of the guide rods 4, 5 or 6. These linear bearings ensure stability in the th bearing the crown of the slide 3 and provide them to move in a certain direction. In the direction of energoakkumulyatorami spring 8 is fixed at the top or bottom one of its end in the respective movable crosspiece on which they rely.

Below the crown of the slide 3 in the same longitudinal direction move jumping the rails 9. Jumping the rails, in turn, also have both sides of the linear bearings 10, which cover one of the guide rods 4, 5 or 6. In the framework of the invention there may be other structural embodiments of the winding carrier 3 and skakovyh slides 9 and reference sites. It is only important that the winding rails 3 and jumping slide 9 do respectively linear motion, indicated in the drawing double arrows.

On skakovyh the carrier 9 at their lower opposite winding the carrier 3 side of the fixed console 11, carrying two face down roller 12, 13. The rollers 12, 13 are arranged so that they are in a horizontal plane on the same line perpendicular to the direction of movement skakovyh sled 9.

This is shown in figure 4. The direction of movement of the console 11, which corresponds to the movement skakovyh sled 9, indicated by a double arrow. On being perpendicular to the line on the console 11 is fixed both rollers 12, 13. Free, facing down the rotating rollers are made.

Both rollers 12, 13 correspond vypolnennoi in a special way the wings 14, which is made in the form of a groove in the disk flywheel 15. The connecting rod 14 is described in more detail below.

Disk flywheel 15, in turn, is connected with the grooved profile 19 of the sleeve 18, which is connected with an output shaft (not shown), transmitting the received rotational movement on the step switch under load and leading him into action.

The connecting rod 14 has an internal circuit 16 and the outer contour 17, while in the middle part both of the circuit 16, 17 are not parallel to each other. In other words, the internal width of the scenes 14 is not constant, but varies. The connecting rod 14 has a Y-shaped contour (figure 3), and the distance between the internal circuit 16 and the outer contour 17 in three areas external sites Y is approximately constant and at least corresponds to the diameter of the rollers 12, 13. Therefore, in these outer areas can be opened with a geometric touch one of the two rollers 12, 13. On average site width scenes 14 increases, so that in this area one of the two rollers 12 or 13 moves freely.

Stages of movement when enabling energy accumulator according to the invention is performed as follows. Drive shaft (not shown) begins to continuously rotate together with the Cam disk 1, which slides on the corresponding powered block 2 and thus moves evadnie the carrier 3 in the longitudinal direction on the guide rods 4, 5, 6. As a result, energoakkumulyatorami springs 8 are tightened. Upon reaching the wind-up carrier 3 its end position, energoakkumulyatorami spring 8 has reached its maximum tension. Up to this point jumping the carrier 9 is still blocked, so they can't make the clockwork movement of the slide 3. Shortly before the end position clockwork sled 3 corresponding control disables the lock is known from the prior art. In the unlock jumping slide 9 now repeat abruptly, under the force of the tense energy-accumulating springs, clockwork movement of the slide 3. As soon as they reach their end position, again it is blocked, i.e. mechanical means jam again jumping the rails 9 in the new position, and the battery energy is ready for the next switch.

Simultaneously with unlocked saccomani the carrier 9 moves also fixed on them the console 11. Both mounted on the console 11 of the roller 12, 13 make parallel trajectories is intermittent linear motion. First, one roller 12 is in mesh with a geometric touch with wings 14 of the flywheel 15. Another roller 13 in the beginning can move freely in the interior, the wide part 14 scenes. Later, x is de linear displacement of both rollers 12, 13, which is initially in engagement with geometric touch the first roller 12 rotates the disk flywheel 15 to until the roller 12 reaches as a result of this rotation of the medium, wide area scenes 14. The rotation of the flywheel 15 changes the position of the scenes 14 relative to the rollers 12, 13. Consequently, the second first freely moving, the roller 13, is adjudged to be in engagement with the geometric touch until then, until it reaches the end position. At the same time the second roller 13 comes out of gear and can move freely without geometric touch.

Linear motion skakovyh slide 9 according to the invention is converted both rollers 12, 13 for three consecutive time plots into rotational motion. First, due to the closure of the first roller 12 in the wings 14 in freely moving the second roller 13, then through the circuit of the second roller 13 in the wings 14 in freely moving the first roller 12 and, finally, again due to the closure of the first roller 12 in the slide 14 with the free movement of the second roller 13.

Due to the mass of the flywheel 15 is particularly preferred manner could be provided by the uniformity of the obtained rotational motion.

During the next actuation of the energy accumulator described the path of movement of the winding of the slide 3 and sachverhalt 9, as well as the conversion of linear movement by means of rollers 12, 13 and 14 scenes in rotational movement of the flywheel 15 is performed in the other direction. The movement of individual structural elements is in the opposite direction; battery power has left and right end position, which in turn change each time you switch.

Described according to the invention the conversion of linear motion into rotational motion provides a number of advantages: firstly, the variation of gear ratio is provided in a simple way; torque is particularly high at the beginning and at the end of the actuation speed of the switch is under load, i.e. when it is necessary. Especially at the end of each switching high torque important to ensure the complete achievement battery energy end position, secure the lock in this end position and, hence, achieving speed switch under load a new stationary position after the switch. The invention provides these advantages.

In addition, the connecting rod 14 due to its geometry may be varied within wide limits. The internal circuit 16 and the outer contour 17 may have a different shape and the distance between the sides This allows you to adapt to a variety of switching options and the sequence of switching operations various manual switches under load.
