Abstract

The invention relates to the technical field of engineering machinery transmission, in particular to a spring resetting type overrunning clutch for an energy-conservation type loader with low rotating speed. An inclined angle between a spring resetting hole and an inner ring cam ranges from 30 degrees to 34 degrees; the diameter of the spring resetting hole ranges from 4.49mm to 4.538mm, and the depth of the spring resetting hole ranges from 15mm to 15.1mm; and the cross section of a roller path wall is circular arc-shaped. The spring resetting type overrunning clutch has a simple structure, a low reduction ratio, large transmission torque, good overloading performance and long service life, is stable in working and safe and reliable, and is beneficial to realizing energy conservation and emission reduction of the domestic loader and improving the performances of the whole loader.

Description

technical field [0001] The patent of the present invention relates to the technical field of construction machinery transmission, in particular to a spring-return type overrunning clutch suitable for low-speed energy-saving loaders. Background technique [0002] At present, there are deficiencies in the number of teeth, material and technical parameters of the traditional spring return overrunning clutch. Chinese patent CN200620140960.9 discloses an improved transmission overrunning clutch, which mainly includes an intermediate input shaft, a cam and an outer ring gear. The central hole of the spring seat is changed from Φ0.8mm to Φ1.0-Φ1.2mm, which enhances the flow capacity of the working medium and dirt, and can reduce the deposition of garbage in the inner cavity of the spring seat. However, the transmission overrunning clutch described in this structure cannot meet the high torque transmission requirements of low-speed energy-saving loaders, and the internal structure ...
