Speed reducer thrust bearing structure

Abstract

The invention discloses a speed reducer thrust bearing structure. A last-stage gear is mounted in an inner cavity of a gear box, a dish-shaped spring is mounted on the last-stage gear, two pairs of thrust bearings are symmetrically mounted on two sides of the dish-shaped spring, and an output shaft is mounted in inner holes of the thrust bearings and the dish-shaped spring. The speed reducer thrust bearing structure has the advantages of compact structure, high automation level, good universality and wide using range, and the defect that thrust bearings are prone to being damaged caused by overload due to the fact that existing speed reducer thrust bearing structures do not have torque limiting functions is overcome effectively.

Description

technical field [0001] The invention relates to a thrust bearing structure, in particular to a thrust bearing structure of a reducer, and belongs to the technical field of mechanical transmission. Background technique [0002] The reducer thrust bearing structure is an important component in mechanical transmission. The reducer thrust bearing plays the role of matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. However, at present, The thrust bearing does not have a torque limiting function, so it is prone to overload and damage to the thrust bearing. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a reducer thrust bearing structure with compact structure, high degree of automation, good general performance and wide application range, so as to overcome the above-mentioned defects of the existing reducer thrust bearing. [0004] Th...
