SU412419A1 - DEVICE FOR TRANSMISSION OF THE TURNING TORQUE THAT PROVIDES AUTOMATIC SPEED SWITCHING - Google Patents

Description

The invention relates to reduction gear. It is known a device for transmitting a torque, providing an axial shift of speeds comprising a drive and driven shaft, a gear, free-wheeling mechanisms installed with a potential (the rotation axis in opposite directions, the drive sleeve of one of which is fixed on the drive shaft, and the knowledge interacts with the follower shaft of the gear pair. The proposed device is characterized by the fact that it is equipped with an additional gear drive, the leading gear, which is clamped onto the drive shaft ( , the friend of the drive holder of the freeway mechanism of a ladiplan on the BeaOiMOM shaft, and its lead clip by means of an additional gear transmission interacts with the drive shaft 0) M. This will turn the speed of the output shaft without changing the direction and rotating it when reversing the drive shaft. Fig. I depicts the proposed device; Fig. 2 is a section along A-A in Fig. 1, and Fig. 3 is a section along B-B in Fig. 1. The proposed device contains a master 1 and a driven 2 shaft, a free mechanism the course, the leading holder .3 of which JCOMM mounted on shaft 1, and the knowledge oboY1.ma 4 podschitnike freely fitted onto the shaft 5 /; ring gear 6, rigidly screwed on the drive ring 3 of the first coupling. In addition, the device has a parasitic gear wheel 7, which is in engagement with the crown 6, a free wheeling mechanism, the drive case 8 of which is freely mounted by means of bearing 9 on the Balu 2 iMOiM bucket and interacts with the wheel 7, and the case 10 is rigidly connected to the shaft 2 and through the ring gear 1 interacts with the bucket, my clip 4. When the drive shaft 1 is turned, clockwise (see Fig. 2) rotates and the drive sleeve 3 fixed on the shaft, rotates in the same direction .me 4, taki ka shar1ki, located between E TIMI of both 1M: and, for 1. The yoke 4 transmits the rotation to the driven yoke 10 of the second free wheeling mechanism via a ring gear 11 and, accordingly, to the driven shaft 2. The driving yoke 8 and the yoke 10 are free one with respect to the other, since the balls between the two are wedged. Simultaneously with the yoke 8, it is meshed through the parasitic wheel 7 with the ring gear 6 of the driving axle 3 of the first free-wheeling mechanism and freely expands relative to the yoke 10,

When rotating the hall / lr by drinking clockwise (see Fig. 3), the moment of rotation is transmitted through the following chain: leading shaft 2, toothed rim 6, parasitic wheel 7, leading shaft 5 and knowing the holder 10. In this case there is a connection between the holder M | Z 5 and 10 for | KL1Ineny.

In this way, the rotation speed of the driven hall 2 was changed when the rotation speed of the drive shaft 1 was changed.
