Problems solved by technology

Due to the support of multiple pairs of bearings, the overall size is large and the structure is complex, which is not conducive to the development and application of lightweight and miniaturization
Secondly, there is a single installation method, only one-sided input and output, inflexible use, and poor versatility. Third, the secondary transmission has the problem of one-sided meshing of gears, and the inertial force generated by the nutating motion of the gears is not easy to offset, resulting in serious vibration and impact. , resulting in reduced service life and poor reliability. Finally, there are problems of high tooth height and small modulus, resulting in tooth root bending and insufficient tooth surface contact strength.
[0003] Aiming at the above problems, a crown gear nutating transmission device was invented, which adopted a new type of crown gear nutating conjugate meshing pair to solve the problems of excessive overall size, input and output on one side, and vibration and impact of meshing on the same side, and can realize "input at the left end, Right end output", "right end input, left end output" two modes of use, and has the advantages of continuous tooth surface, axial backlash elimination, double-sided meshing, multi-line contact, etc., which is beneficial to reduce tooth surface wear and backlash, and improve smooth movement performance and carrying capacity

Abstract

The invention discloses a nutation transmission device of a cambered secondary enveloping crown gear, which is characterized in that it comprises a crossed roller bearing, a right end crown gear, a left end crown gear and a nutation crown gear, and the crossed roller bearing comprises The inner ring and the outer ring are rollingly connected, the inner ring is fixedly connected with the left crown gear, the outer ring is fixedly connected with the right crown gear, and the nutating crown gear is arranged on the Between the right-end crown gear and the left-end crown gear, the tooth surface of the left-end crown gear and the left tooth surface of the nutating crown gear form a left-side less-tooth difference nutation conjugate meshing pair, and the tooth surface of the right-end crown gear and the nutating crown gear. The right tooth surface of the nutating crown gear constitutes the right side less tooth difference nutating conjugate meshing pair. The crown gear of the present application has continuous tooth surfaces, and all of them participate in meshing, which can reduce the wear of the tooth surfaces, easily form a lubricating oil film, and improve the transmission efficiency of the device.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a nutation transmission device of a cambered secondary enveloping crown gear. Background technique [0002] At present, the traditional nutation transmission device mostly adopts the meshing pair of involute bevel gear, the meshing pair of bevel oscillating pin gear, the meshing pair of rolling bevel movable tooth, the meshing pair of double arc spiral bevel gear and so on. Due to the support of multiple pairs of bearings, the whole is large and the structure is complex, which is not conducive to the development and application of lightweight and miniaturization. Secondly, there is a single installation method, which can only be input and output on one side, which is inflexible in use and has poor versatility. Thirdly, the secondary transmission has the problem of gear meshing on one side, the inertial force generated by the gear nutation movement is not easy to offset,...
