CS276048B6 - Trochoidal rolling gear speed reducer - Google Patents

Abstract

The trochoid rolling reducer consists of a housing (1) provided with a hypocycloid gear, in which a disc (2) provided with an epicyclic gear is supported by an input shaft (3) with an eccentric. The connection of the housing (1) to the disc (2) is provided by the rollers (5) in the cage (7) with the rotatable housings (6). The rollers (5) are fixedly fixed in the cage (7) which is connected to the carrier (10) mounted in the lid (12) by means of the sleeves (9) rotatable on the pins (8).

Description

The invention relates to a trochoid rolling reducer.

Previously known embodiments of trochoid rolling reducers consist of an outer and an inner element, the outer of which has a hypocycloid-shaped toothing on its inner side and an epicycloid-shaped toothing on its outer side.

In the space between these elements, the rollers are housed in a cage.

There are also known embodiments of trochoid rolling reducers, which consist of two inner elements having an external epicycloid toothing on the outside. In both inner elements, the pins are fixedly connected to the output shaft. The inner elements are movably mounted on a shaft provided with two excerpts. Both inner elements roll in the coil ring and the output shaft pins.

A disadvantage of the presently known configurations of toroidal roller reducers using a roller cage is that it does not allow torque transmission and hence increased gear ratios while retaining the flood components.

This disadvantage is overcome by the threoid rolling reducer according to the invention, which is characterized in that the sleeve rollers are firmly fixed in the roller cage and connected to the carrier by means of sleeve pins.

The solution according to the invention makes it possible to achieve an increase in transmission ratios while retaining the original components.

In the drawings, an exemplary embodiment of a trochoid rolling reducer according to the invention is shown. 1 is a longitudinal section and FIG. 2 and 3 are cross-sectional views of a trochoid rolling reducer.

The trochoid rolling reducer consists of a housing 2 'which is provided with a hypocycloid toothing on its inside. In the housing 2, a disc 2, which is provided with an epicycloid toothing on its outer side, is supported by an eccentric input shaft 2 via the bearing 4. Connection cabinets 2 ³ disc 2 providing rollers embedded in the casing it, which is rotatable about the axis of the rollers 5>. The rollers 2 with the sleeves 6 are fixedly fixed in the roller cage T. The roller cage 2 is connected to the carrier 10 by means of bushings 9 rotatable in pins 5. the pins 2 are fixedly fixed in the carrier 10, which is supported by a bearing 11 in the lid 12.

The drive motor (not shown) actuates the input shaft 2 with eccentric rotation via the bearing 6 in a rotational movement. From the input shaft 2 through the cam bearing £ the movement transmitted to the wheel 2, which rotates in the opposite direction of rotation of the input shaft 2 ³ eccentric. From the roll 2 ^{through the} rollers 2 ^{with the} bushes ^{3a and through the} roll cage T of the rollers 2 by means of the pins 2 ³ through the bushes 2, it transmits the rotary movement to the carrier 10, ^from which it is taken to the output shaft (not shown).

The throchoid rolling reducer according to the invention finds application in mechanical engineering, especially in robotics and automation, and wherever the transmission of high gear ratios is required.
