Abstract

The invention relates to the technical field of engineering machinery transmission, in particular to a spring reset type overrun clutch applied to an energy-saving loader with low rotating speed. An included angle between a spring reset hole and an inner ring cam is 30 degrees-34 degrees, the diameter of the spring reset hole is 4.49mm-4.538mm, the depth of the spring reset hole is 15mm-15.1mm, and a cross section of a raceway wall is in a circular arc shape. The overrun clutch has a simple structure, low reduction ratio, large transmission torque, favorable overload performance, stability in operation, safety and reliability and long service life, and is beneficial for realization of energy conservation and emission reduction as well as improvement of whole machine performances of a domestic loader.

Description

Technical field [0001] The patent of the invention relates to the technical field of engineering machinery transmission, in particular to a medium tonnage energy-saving and environmentally-friendly roller cage overrunning clutch for loaders using a low-speed engine and a large-capacity torque converter. Background technique [0002] At present, domestic loader manufacturers are developing medium-tonnage energy-saving and environmentally-friendly loaders. They use multi-specification low-speed engines with a rated power of 154~162Kw and a rated speed of 2000r / min. With a large capacity torque converter, the torque can reach Above 2500Nm. The bearing capacity of structural parts and various system components of loaders in the prior art, especially the overrunning clutch, can no longer be adapted, and its failure rate has increased significantly, which has become an urgent problem in the loader industry. Chinese patent CN200620140960.9 discloses an improved transmission overr...
