SU1216491A1 - Transmission for parallel shafts with intermediate rollers - Google Patents

Description

one

The invention relates to mechanical engineering and can be used as high-precision motion transducers.

The purpose of the invention is to increase the smoothness of the transmission.

FIG. 1 shows a gear for parallel shafts with ball intermediate bodies, a section; FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; FIG. 4 is a section B-B in FIG. one.

The transmission contains a driven disc with a cut on its end surface with teeth 2 and 3 of direct and reverse contact, which interact with the balls 4. The drive disk 5 and the additional compensator disc 6 with spherical recesses on the i-tx end surfaces are installed. x, in which the balls 4 are installed. The drive disc 5 and the compensator disc 6 are provided with pins 7 interconnected in pairs by tensioning springs 8. In this case, the drive disc 5 and the compensator disc 6 have the possibility of mutual rotation under the action of tension springs 8.

The transmission works as follows.

12164912

When the drive disk 5 rotates, the rotation transfer process is performed by the balls 4, located in the spherical recesses of the drive disk 5, through the points of direct contact K (Fig. 4) with the tooth 2 of the driven disk I. Under the action of the tension springs 8 self-disk-compensator 6 to the appearance

0 points O (Fig. 4} of the reverse contact of the balls 4 installed in the spherical recesses and the teeth 3 of the driven disc 1. When the direction of rotation of the driving disc is changed by 5 points, the points of the direct drive contact will become points O and points K - the points of return contact.

In view of the fact that there are points of direct K and reverse contact, the backlash due to the technology of the gearing manufacture will be excluded. The gaps arising during operation, which are associated with the wear of the gearing engagement elements, will be automatically compensated by an additional rotation of the compensator disk 6 until the points of reverse contact O are formed under the action of the tension springs 8. Stress

30 of the spring 8 in this case must be designed for the transmission of torque and compensating rotation.
