Embodiment Construction

[0024] exist figure 1 Among them, the left and right disks 3 and 10 are respectively located in the symmetrical step-shaped circular holes at the left and right ends of the main body 5, and the outer surfaces of the left and right ends of the left and right disks 3 and 10 have symmetrical annular stepped surfaces. The annular stepped surface on the outer surface of the right end of the disk 3 and the annular stepped surface on the outer surface of the left end of the right disc 10 are respectively equipped with rollers 18 arranged at intervals in the axial and radial directions, that is, special radial / axial bearings or cone bearings. The roller bearing replaces the roller, and the roller is movably matched with the corresponding end surface and the corresponding inner wall of the step-shaped circular hole in the left and right ends of the main body 5; The ring-shaped groove surrounded by the ring-shaped step surface on the outer surface of the outer surface and the inner wall...

Abstract

The invention relates to a dual round disc cycloid wheel planet transmission device, providing a planetary reducer with fewer teeth differ, which can solve the problems of present cycloid planet reducer which can not bear bigger external axial force and need special frame with worse dynamic balance property and lower N-N transmission efficiency. The invention comprises a main body, an input axle, a roller, needle teeth, and a sleeve, left and right round discs, cycloid planet wheel, teeth sheath, and pin sheath and connection elements. Wherein, the dual-eccentric bearings, the pin sheath, the teeth and the teeth sheath are inside the cylinder hole which is in the middle of main body between the left and right round discs; the needle wheel formed by the needle teeth, the teeth sheath, and the main body can form a cycloid planet meshed pair with the cycloid planet wheel. The invention has better bearing capacity, especially bearing bigger external axial force with better dynamic balance property, easy production, N-type transmission, a meshed pair and a slit adjustable device. It can attain high transmission accuracy and efficiency while it can realize coaxial output since the dual round disc output element has symmetry functions.

Description

Technical field: [0001] The invention relates to a planetary reducer with small tooth difference, which is a precision transmission and power transmission device. Background technique: [0002] On May 14, 2003, Chongqing University submitted an invention patent application to the State Intellectual Property Office with the "Conical Cycloid Planetary Transmission Device", the application number is 03117879.0, and was granted the invention patent on February 16, 2005. The device includes a main body, a right support fixedly connected with the main body, a pre-tightening member located at the right end of the right support, the left end of the eccentric shaft equipped with a balance weight is supported by a bearing installed in the through hole at the left end of the main body, and its right end is supported by a bearing installed in the output member. The bearing in the blind hole at the left end is supported, and the output member is supported by the bearing and seal in the r...
