Embodiment

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

[0030] (1) The central gear 7 is an internal gear, the planetary gear 5 is an external gear, Z 1 =50,Z 2 = 49, h = 0, then an intersecting shaft universal less tooth difference reducer mechanism with a reduction ratio of 50 is obtained, which can be used for intersecting shaft intersecting shaft co-direction reduction transmission with the shaft angle 2δ≠180°;

[0031] (2) The central gear 7 is an external gear, the planetary gear 5 is an internal gear, Z 1 =50,Z 2 = 51, h = 0, then an intersecting shaft universal less tooth difference reducer mechanism with a reduction ratio of -50 can be obtained, which can be used for intersecting shafts with an intersecting shaft angle of 2δ≠180° for reverse reduction transmission;

[0032] (3) The central gear 7 is an internal gear, the planetary gear 5 is an external gear, Z 1 =50,Z 2 =40, h=0, then an intersecting shaft univ...

Abstract

An internal 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, a central gear with a rotary shaft in axle of B and bearing chocks, and an epicyclical frame. The planetary and the central gear are engaged internally. The epicyclical frame is rotated in the axle of B fixedly. The planetary is supported on the said frame with a revolving pair. C is in parallel with A, and D is in parallel with B. Their off distances are equal. 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 internal 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...
