Embodiment

[0031] The calculation example of the mechanism transmission ratio of the present invention is as follows:

[0032] (1)Z 1 =20,Z 2 =19, h=0, then a reduction ratio of 20 intersecting shaft universal less

[0033] Tooth difference planetary synchronous belt wheel reducer mechanism, which can be used for co-direction reduction transmission between intersecting shafts with shaft angle 2δ≠180°;

[0034] (2)Z 1 =20,Z 2 = 21, h = 0, then a planetary synchronous belt wheel reducer mechanism with intersecting shaft universal direction and small tooth difference with a reduction ratio of -20 can be obtained, which can be used for reverse reduction transmission between intersecting shafts with an intersecting shaft angle of 2δ≠180°;

[0035] (3)Z 1 =20,Z 2 =16, h=0, then an intersecting shaft universal planetary synchronous pulley reducer or a reverse speed-up transmission mechanism with a reduction ratio of 5 can be obtained, which can be used for the same direction deceleration ...

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, especially a new type of transmission mechanism capable of universal deceleration or reverse speed up, which is invented by comprehensively utilizing the transmission principles of planetary synchronous pulleys and universal couplings. Background technique [0002] The reducer is a commonly used mechanical transmission device, and there are many types of transmission mechanisms. However, various existing reducer products can only provide inter-shaft reduction transmission with relatively fixed positions. For example, a cylindrical gear mechanism generally provides transmission transformation between two parallel shafts with a fixed relative position; an ordinary spur bevel gear mechanism can be used for transmission transformation between two intersecting shafts with a fixed relative position; a worm reducer or a helical gear mechanism is generally used for relative Reduction transmission ...
