[0013] Example: heat dissipation device for variable frequency motor

[0014] See attached figure 1 And attached figure 2 As shown, the heat dissipation device for the frequency conversion motor includes a heat dissipation impeller 5, the center of the heat dissipation impeller 5 is fixed with a disc-shaped base 6, and an intermediate gear 1 is fixed on the disc-shaped base 6; the intermediate gear 1 There is a through hole in the center of the center, the through hole is divided into two sections, one section is the motor shaft accommodating section 2, and the other section is the inner spline section 3; the diameter of the motor shaft accommodating section 2 is larger than the inner spline section 3, The junction of the two constitutes a stepped portion, and the motor shaft accommodating section 2 is provided with a groove 4 at the junction with the inner spline section 3 . Since the groove 4 is provided at the junction of the motor shaft accommodating section and the inn...

Abstract

A heat sink for a variable frequency motor provided by the invention comprises a radiating impeller. A disc-shaped pedestal is fixed at the center of the radiating impeller, and an intermediate gear is fixed on the disc-shaped pedestal; a through hole is arranged at the center of the intermediate gear and is divided in two sections, one section is a motor shaft containing section, and the other section is an internal spline section; and the diameter of the motor shaft containing section is larger than the diameter of the internal spline section, a step portion is formed at the combination position of the motor shaft containing section and the internal spline section, and grooves are arranged at the connection position of the motor shaft containing section and the internal spline section. Because the grooves are arranged at the connection position of the motor shaft containing section and the internal spline section, the root of the motor shaft and the intermediate gear cannot be worn by friction.

Description

technical field [0001] The invention relates to a cooling device for a variable frequency motor, which belongs to the technical field of accessory parts of washing machines. Background technique [0002] The frequency conversion motor of the drum washing machine will generate a lot of heat during operation, and too much heat is not good for the operation of the frequency conversion motor. At the same time, the interior space of the washing machine is limited, and there are strict requirements on the volume of the cooling device. In order to cooperate with the installation of the cooling device of the frequency conversion motor of the drum washing machine, it is necessary to design a connection device. The publication number is CN202867594U, and the utility model patent titled "An Intermediate Gear for Connecting Frequency Converter Motor Radiating Device" discloses a technical solution: the intermediate gear is connected to the center of the cooling impeller through an inte...
