Abstract

The invention provides a small tooth difference planetary reducer, and belongs to a motor driving device. The small tooth difference planetary reducer comprises a machine base group (12) arranged on the periphery of the reducer and a bottom plate (15), an input eccentric shaft (5) which is fixed through a first bearing (6) and the machine base group (12), a planetary wheel (9) fixed on the input eccentric shaft (5) and an inner gear (7) positioned on the periphery of the planetary wheel (9), wherein the input eccentric shaft (5) is provided with two eccentric shaft sections which are arranged in a 180-degree manner; the two eccentric shaft sections are respectively provided with the planetary wheel (9) through a second bearing (11), more than six pin holes (9-1) are uniformly distributed on the planetary wheel (9), and the pin holes (9-1) are provided with pin shafts (10) which axially pass through the planetary wheel (9); and the pin shafts (10) are of a simple support beam structure, and the two ends of the pin shafts (10) are respectively fixed on the machine base group (12). The invention also provides an elevator traction machine using the small tooth difference planetary reducer. The small tooth difference planetary reducer provided by the invention has the advantages that compared with the prior art, the structure is simple and compact, the stressing of the complete machine structure is balance, the running noises and vibration are small, and the cost is low.

Description

technical field [0001] The invention relates to a planetary gear reducer with small tooth difference, which belongs to the motor reducer; the invention also relates to an elevator traction machine using the reducer. Background technique [0002] The planetary gear reducer with small tooth difference is a kind of reducer widely used in the motor field. In the elevator market, especially the freight elevator traction machine has the characteristics of large load and high torque, and the gear reducer is widely used. traction machine. The common geared traction machine is mainly the worm gear drive traction machine, which is widely used because of its simple manufacture and low cost, but this type of traction machine has low operating efficiency, poor maintenance and short service life. However, gearless traction machines such as permanent magnet synchronous gearless traction machines, NGW planetary gear traction machines, etc., are energy-efficient and reliable in operation, b...
