Disc type coaxial deceleration reversing device

Abstract

The invention relates to a disc type coaxial deceleration reversing device, and belongs to the technical field of mechanical deceleration transmission. The deceleration reversing device consists of anupper deceleration reversing part, a middleware, a lower deceleration reversing part, an upper device cover and a lower device cover, and the upper and lower deceleration reversing parts are connected with each other through the middleware, an upper bearing and a lower bearing in a fastening mode, the upper device cover is arranged on the upper deceleration reversing part, the lower device coveris arranged on the lower deceleration reversing part, and the upper device cover, the middleware and the lower device cover are fixed with each other through fastening bolts. The device is compact insize and convenient to process, when the device is working, a small disc shaft is used as the input, when the disc shaft rotates, a movable pin is pushed to move reciprocatingly in a sliding hole, because the middleware is kept fixed, the movable pin pushes a large disc annular groove to drive the lower deceleration reversing part to rotate, because the wave crest numbers of the cycles of the small disc annular groove and the large disc annular groove are not equal, the output of the large disc shaft on the lower deceleration reversing part is lagged behind, thereby the purpose of decelerationand reversing is achieved, and the disc type coaxial deceleration reversing device has broad application prospect.

Description

Technical field [0001] The invention relates to a disc type coaxial deceleration reversing device, belonging to the technical field of mechanical deceleration transmission. Background technique [0002] Coaxial reduction gears are mostly found in planetary reducers, but the meshing of their gears will produce impact impact loads, and long-term alternating loads will affect the working performance. In addition, the radial size of the planetary reducer is relatively large due to multiple planetary gears, which is often not suitable for occasions with limited installation dimensions. [0003] At present, the existing coaxial reversing device mainly has four bevel gear combinations, which have the same disadvantages as the planetary reducer. Gear meshing causes collision and impact loads. The combination of multiple bevel gears often results in large radial dimensions. , Also not suitable for occasions with limited installation size.

Problems solved by technology

[0002] Coaxial reduction gears are mostly found in planetary gear reducers, but the gear meshing will generate collision impact loads, and the long-term alternating loads will affect the working performance

In addition, the radial dimension of the planetary reducer is relatively large due to the multiple planetary gears, so it is often not suitable for occasions where the installation size is limited.

[0003] At present, the existing coaxial reversing device mainly has the combination of four bevel gears, which has the same disadvantages as the planetary reducer. The meshing of the gears leads to collision impact loads, and the combination of multiple bevel gears often results in large radial dimensions. , also not suitable for occasions where the installation size is limited

[0004] Cylindrical sinusoidal movable tooth transmission, although it can achieve deceleration and reversing functions in a small radial dimension, the processing of its spatial curved groove is complicated; installation is troublesome, and it is necessary to drill holes in the side wall to take out blocks and throw balls, and at the same time, it must ensure space The integrity of the curved groove; and its closed cavity is not conducive to heat dissipation
