Abstract

The invention discloses a multi-row precise ball speed reducer. The speed reducer comprises a center disc, an input shaft, bearings, speed reducing balls, an outer shell, planet discs, equal-speed balls, output shafts and gap adjusting discs. The input shaft is provided with n sections of eccentric shafts, wherein n is a positive integer of not smaller than 1; the bearings are mounted on the eccentric sections of the input shaft; and the planet discs, center discs and the output shafts are mounted on the bearings. Multiple speed reducing engagement pairs are designed in speed reducing mechanisms; and multi-line-section annular grooves are designed in annular groove equal-speed mechanisms. Multiple speed reducing mechanisms are arranged in multistage multi-row ball speed reducers; and the speed reducing mechanisms can be connected through the equal-speed mechanisms. The eccentric shaft sections of the input shaft drive the planet discs to move through the bearings; the change of the rotating speed is realized by the speed reducing mechanisms; and the fixed-shaft outputting of the rotating speed is realized through elimination of eccentricity of the planet discs by the equal-speed mechanisms. The multi-row precise ball speed reducer is simple and compact in structure, high in transmission efficiency and low in noise, and can continuously eliminate tooth side gaps of engagement pairs; multiple rows of speed reducing steel balls are mounted on the speed reducing mechanisms to improve the bearing capacity; and the diameters of the equal-speed balls in the multi-line-section annular grooves are not limited by eccentric distances to achieve high bearing capacity.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a multi-row precision ball reducer. Background technique [0002] The reducer is an important part of the machinery industry, and its transmission performance directly affects the production efficiency, work performance and product quality of the machinery. The carrying capacity of modern high-precision transmission mechanisms is limited, and its transmission performance will inevitably be affected, which cannot meet the requirements of transmission accuracy and carrying capacity in industrial production at the same time. [0003] In the cycloidal steel ball planetary reducer, the decelerating meshing pair has only one row of decelerating steel balls, and its load capacity is weak, which limits the application range of this type of reducer. The constant velocity mechanism in the cycloidal ball planetary reducer is designed with a constant velocity meshing pair, a...
