Aluminum alloy shell casting of motor of electric car

Abstract

The invention discloses an aluminum alloy shell casting of a motor of an electric car. The shell casting comprises a first shell and a second shell; semicircular first placing grooves are arranged on the opposite side walls of the first shell body and the second shell body; two bosses are symmetrically arranged on the inner walls of the first placing grooves; a rotor limiting slot is arranged on one side wall of the first shell body; an oil filling pipeline for filling the lubricant is arranged between the boss and the rotor limiting slot; a semicircular rotor limiting block is fixedly connected on the outer wall of the bottom of the oil filling pipeline; a rotor rotating slot is arranged on the other side wall of the rotor limiting block; the rotor rotating slot is connected with the oil filling pipeline; a vent hole for exchanging the air heat is arranged on the inner wall of the top of the first shell; a connection pipe is sleeved on the bottom of the vent hole; one end of the connection pipe far from the vent hole is fixedly connected with a vent pipe; and a vent hole is arranged on the outer wall of the top of the vent pipe. The aluminum alloy shell casting has good heat dispersion performance and good vibration reducing performance.

Description

technical field [0001] The invention relates to the technical field of industrial manufacturing, in particular to an aluminum alloy shell casting of an electric vehicle motor. Background technique [0002] The motor is a very common device in the mechanical field. Its function is to provide power to various mechanical equipment. The basic structure of the motor includes the core and the shell. The shell is used to protect the core and also to dissipate heat from the core to avoid The core burns out at high temperature. The structure of the motor casing mainly includes a cylindrical casing, and then uniformly distributed convex corrugations are arranged axially on the cylindrical casing, and the function of setting the convex corrugations is to help heat dissipation. [0003] The heat dissipation effect of the existing motor housing is not very good, especially for motors with high power, which has a large calorific value and cannot dissipate heat in time, which shortens the...
