An electric preformed reducer housing with double helix cooling channel

Abstract

The application provides an electric pre-plastic reduction gear shell with double-helix cooling channels, comprising: a mounting block, one side of the mounting block being provided with a motor, the other side of the mounting block being provided with a shell, one side of the shell being provided with a fixing block; a cooling assembly, the cooling assembly being arranged in the shell, the cooling assembly comprising: an oil collecting groove, a first cooling pipe and a second cooling pipe; a filtering assembly, the filtering assembly being arranged in the shell, the filtering assembly comprising: an arc-shaped plate, a mounting slide plate, a mounting groove and a filter screen; a lubricating assembly, the lubricating assembly being arranged in the shell, the lubricating assembly comprising: a planet carrier and a fixing plate. The shell is provided with the cooling assembly, so that the cooling liquid forms double-helix counter flow in the shell, the temperature unevenness problem of the traditional single-helix channel, that is, the cold inlet and the hot outlet, is eliminated, the lubricating oil is cooled, the built-in sliding filtering assembly is used to realize online oil purification, the wear condition is reduced, and the lubricating assembly is used to improve the oil supply amount and the oil supply lift of the gear.
