Abstract

The invention provides a gear. A shaft hole is arranged on the gear, gear teeth are arranged on the circumferential direction of the gear, and the gear teeth are not constant-breadth gear teeth. The gear is light in weight and capable of saving materials to the greatest extent and achieving the light weight and an isostress design or an approximate isostress design on the premise that the strength requirement is met. The invention also provides a transmission system containing the gear and an engineering machine containing the transmission system.

Description

Technical field [0001] The present invention relates to the field of gear transmission, in particular to a gear, a transmission system including the gear, and an engineering machine including the transmission system. Background technique [0002] At present, the cylindrical gears in general gear transmission mechanisms at home and abroad are usually designed with a tooth width of equal width. For this type of gear, in the gear rotation process, the force of each gear tooth of the gear is constant within a certain range, and the force of each gear tooth is not equal and has a large difference. [0003] Gears in the related art have at least the following shortcomings: the transmission is unstable when the forces of the respective gear teeth are not equal, the degree of wear of each gear tooth is different, and material is wasted. Summary of the invention [0004] In order to solve the above-mentioned problems, the present invention provides a gear, which can reduce the weight of the...
