Description

The invention relates to mechanical engineering and can be used in all sectors of the economy to change the speed and torque.

A known transmission with intermediate links, comprising a housing, an eccentric with a bearing mounted on it, an outer ring of which a cup is mounted, a clip, in the radial grooves of which are movably mounted U fingers connected by a spring ring, a rigid wheel G1J.

- However, the trajectory of the fingers is close to a sinusoid and does not correspond to the profile of a triangular tooth, i.e. .. does not provide a continuous one. . contact, which leads to rapid wear of parts due to the uneven distribution of load on the fingers.

'The purpose of the invention' is to increase the reliability of transmission.

This goal ^{1 is} achieved by the fact that the transmission with intermediate links, containing an eccentric with a bearing mounted on it, on the outer ring of which a glass is mounted, a cage, in the radial grooves of which the fingers are movably mounted connected by a coupling spring ring and a pinion wheel , engaging with fingers, is provided with a spring ring placed between the glass and the fingers, the inner diameter of which is larger than the outer diameter of the glass.

In FIG. 1 shows a transmission with Intermediate links,

lengthwise cut; in FIG. 2 - the same, transverse section,

The drive shaft 1 is made by an eccentric 2 equipped with a rolling bearing 3 and a cup 4, on which freely, with the possibility of elastic deformation / a spring ring 5 is put on, the inner diameter of which is larger than the outer diameter of the cup 4. The fingers 7 are pressed to the latter with a clamp ring 6, the clips 8 sliding in the radio / Other grooves and engaged in engagement with the rollers 9 of the fixed wheel 10. The clip 8 is made integral with the driven shaft 11. ¹

The eccentricity of the eccentric is greater than ¹ eccentricity of the ring, .a. the outer diameter of the cup 4 is less than the inner hole of the ring 5 by twice the difference between the eccentricities.

The installation of the cup 4 on the bearing 3 is caused by the need to increase the strength of the bearing ’.

In the process, the eccentric 2 receives rotation from the drive shaft 1 and moves the fingers 7 through the glass 4, and the latter forces the wheel 10 to rotate. The outer diameter of the ring 5 is half the sum of the axes of the ellipse and an echo chamfer is made on one side, facilitating; 7. ring entry into the hole during indentation. Ring 5 takes the form of from-. a verst and contacts all fingers 7 without exception, respectively, evenly distributes the load 35 between them during transmission operation. ;
