Embodiment Construction

[0026] See attached figure 1 . The double-set cycloidal gear planetary transmission mechanism with equal load on the column pins includes four identical cycloid gears 1, eccentric bearings or eccentric sleeves and bearings 2, input shaft 3, pin wheel 4, and column pins 5, and the four identical The respective circle centers Opi of the cycloidal gears 1 are evenly distributed on the center Oc of the multi-pin wheels 4 of the cycloidal planetary transmission mechanism, on a circle with the eccentricity A as the radius Rai, with an error of ±5 degrees; the axial directions of the Opi do not coincide with each other ; And the front and back positions of four identical cycloid gears are irrelevant.

Abstract

The present invention relates to a dowel pin uniformly-loaded double-group cycloidal gear epicyclic transmission mechanism, including four identical cycloidal gears, eccentric bearing, or eccentric sleeve and bearing, input shaft, pin gear and dowel pin. It is characterized by that the respective centre Opi of four identical cycloidal gears are uniformly distributed on the cycle using shared pin gear of the cycloidal gear epicyclic transmission mechansm as centre Oc and using eccentric distance A as radius Rai, and its error is plus or minus 5 deg. All the OPi are mutually not coincident axially are the front and rear positions of said four identical cycloidal gears are regardless.

Description

technical field [0001] This technology belongs to the planetary transmission mechanism, which is widely used in transmission machinery and equipment in various industries such as mining, metallurgy, shipping, transportation, lifting, chemical industry, construction, and textiles. Background technique [0002] The existing double-set cycloidal gear planetary transmission mechanism does not realize the equal load of the column pins ( figure 2 , image 3 ), its structure is: the input shaft 3 transmits the torque to the eccentric bearing 2 or the eccentric sleeve + bearing, the cycloid gear 1 acts as a star wheel for revolution and rotation, and then the cycloid gear transmits the torque to the pin 5 ( Figure 4 ). This installation form is that the center Op1 or Op2 of any cycloidal wheel in the rear group coincides with the center Op3 or Op4 of any cycloidal wheel in the front group when viewed from direction A. figure 2 and image 3 There are overlaps; Figure 4 and F...
