Embodiment

[0029] The calculation example of the transmission ratio of the mechanism of the present invention is as follows:

[0030] (1)Z 1 = 20, Z 2 =19, h=0, then a universal planetary synchronous belt wheel reducer mechanism with intersecting shafts with a reduction ratio of 20 with a small tooth difference can be obtained, which can be used for the same-direction deceleration transmission between intersecting shafts with a shaft angle of 2δ≠180°;

[0031] (2)Z 1 = 20, Z 2 = 21, h = 0, then an intersecting shaft universal planetary synchronous belt wheel reducer mechanism with a reduction ratio of -20 with little tooth difference can be obtained, which can be used for reverse deceleration transmission between intersecting shafts with a shaft angle of 2δ≠180°;

[0032] (3)Z 1 = 2 0 ,Z 2 =16, h=0, then a kind of intersecting shaft universal planetary synchronous belt wheel reducer or reverse speed increasing transmission mechanism with a reduction ratio of 5 can be obtained, which can be u...

Abstract

A synchronous epicyclical gear consists of a rotary shaft A, a rotation arm, a connecting shaft connected with the said arm by a cylindrical pair in axle of C, a servo planetary D, a connecting shaft to form a shift pair with the servo planetary, a central synchronizing gear with a rotary shaft in axle of B and bearing chocks, a synchronizing belt and an epicyclical frame. The epicyclical frame is rotated in the axle of B fixedly. The servo planetary D is supported on the said frame with a revolving pair. C is in parallel with A, and D is in parallel with E and B. The off distance of D to B is equal to that of C to A. The idler is engaged with the planetary and the central gear. Both connecting shafts are connected with a revolving pair in a axle of co-perpendicular line of C and D. This invention can be used for connection of shafts in various angles.

Description

Technical field [0001] The invention relates to a new type of transmission mechanism, in particular to a new type of transmission mechanism that can be used for universal deceleration or reverse acceleration, which is invented by comprehensively utilizing the transmission principle of planetary synchronous belt wheels and universal couplings. Background technique [0002] Reducer is a commonly used mechanical transmission device, and there are many types of transmission mechanisms. However, the existing various reducer products can only provide a fixed relative position of the inter-shaft reduction transmission. For example, cylindrical gear mechanisms generally provide transmission transformation between two parallel shafts with fixed relative positions; ordinary straight-tooth bevel gear mechanisms can be used for transmission transformation between two intersecting shafts with fixed relative positions; worm reducers or helical gear mechanisms are generally used for relative tr...
