Embodiment

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

[0030] (1)Z 1 =20,Z 2 =19, h=0, then an intersecting shaft universal less tooth difference reducer mechanism with a reduction ratio of 20 can be obtained, which can be used for intersecting shaft intersecting shaft co-direction reduction transmission with an angle of intersection 2δ≠180°;

[0031] (2)Z 1 =20,Z 2 =21, h=0, then an intersecting shaft universal less tooth difference reducer mechanism with a reduction ratio of -20 is obtained, which can be used between intersecting shafts where the shaft angle 2δ≠180°

[0032] Reverse deceleration drive;

[0033] (3)Z 1 =20,Z 2 =16, h=0, then an intersecting shaft universal reducer or reverse speed-up transmission mechanism with a reduction ratio of 5 is obtained, which can be used for the same-direction speed-down or reverse speed-up transmission between intersecting shafts with an angle of 2δ≠180°;

[0034] (4)Z 1...

Abstract

An external engaged 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 planetary D, a connecting shaft to form a shift pair with the planetary, an idler pulley in axle E, a central gear with a rotary shaft in axle of B and bearing chocks, and an epicyclical frame. The epicyclical frame is rotated in the axle of A fixedly. The planetary and the idler pulley are supported on the said frame with revolving pairs. 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 external meshing planetary gears 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 reduction transmission between input and output shafts with relatively fixed positions. For example, a cylindrical gear mechanism generally provides transmission conversion between two parallel shafts with a fixed relative position; an ordinary spur bevel gear mechanism can be used for transmission conversion between two intersecting shafts with a fixed relative position; a worm mechanism or a helical gear mechanism is generally used for relative positio...
