Problems solved by technology

[0002] Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. When the gears are prone to relative sliding and offset during the transmission process, it will not only damage the transmission efficiency, but also easily damage the gears, which greatly shortens the service life of the gears. The seat needs to have strong wear resistance and mechanical properties

Abstract

The invention discloses a gearbox aluminum casting fixing base which is made of an aluminum alloy. The gearbox aluminum casting fixing base comprises a gearbox aluminum casting fixing base body and a gearbox aluminum casting fixing base cover. A first through groove, multiple grooves, threaded holes and pin holes are formed in the gearbox aluminum casting fixing base body. A second through groove, a third through groove, a fourth through groove, a fifth through groove, threaded holes and pin holes are formed in the gearbox aluminum casting fixing base cover. According to the gearbox aluminum casting fixing base, the gearbox aluminum casting fixing base body and the gearbox aluminum casting fixing base cover are combined to form a whole, a gear can be fixed more firmly, meanwhile, the groove structure and the pin holes in the gear fixing base make the gear difficult to deviate, and the gearbox aluminum casting fixing base has high abrasion resistance and mechanical strength.

Description

technical field [0001] The invention relates to mechanical tooling, in particular to a fixed seat of an aluminum casting of a gear box. Background technique [0002] Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. When the gears are prone to relative slip and offset during the transmission process, it will not only damage the transmission efficiency, but also easily damage the gears, which greatly shortens the service life of the gears. The seat needs to have strong wear resistance and mechanical properties. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a gear fixing seat that improves the stability, wear resistance and mechanical properties of gear transmission and prevents gears from shifting, aiming at the above-mentioned shortcomings of the prior art. [0004] The present invention solves its technical problem, and the adopted technical solution is to propose a...
