Embodiment Construction

[0050] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0051] Such as figure 1 and figure 2 As shown, a motor stator housing assembly with groove design based on an elastic mechanics model according to the present invention includes a stator 1 and a housing 2 , and the stator 1 is interference-fitted in the housing 2 . The outer surface of the stator 1 is provided with a groove 4, the groove 4 is a groove texture, the design of the groove 4 reserves a certain deformation space for the stator 2, and reduces the shell deformation caused by interference fit in cold weather conditions. Body 1 risk of bursting. However, the stator 1 is a key component in the electric motor, and it needs to have good strength to withstand and transmit large torque when used in conjunction with the rotor. Th...

Abstract

The invention relates to a motor stator housing component with a groove designed based on an elastic mechanical model and a groove designing method. Compared with the prior art, the defect that a motor stator housing installation structure can not meet actual use requirements is overcome. The motor stator housing component comprises a stator and a housing, wherein the stator is assembled in the housing in an interference mode, the groove is formed in the outer side face of the stator and is parallel to the axis of the stator, and the groove is rectangular when looked down in the radial direction of the stator and is in the shape of an annular sector when looked down in the axial direction of the stator. By additionally designing the groove for accommodating heat-conducting glue in the outer circle of the stator, working stability and safety of a motor are guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle motors, in particular to a motor stator housing assembly and a groove design method for groove design based on an elastic mechanics model. Background technique [0002] Under the double pressure of "environmental pollution" and "energy crisis", the development of energy-saving and environment-friendly new energy vehicles has become the future development direction of the world's automobile industry. As a key component of new energy vehicles, motor is one of the core technologies to promote the development of new energy vehicles. [0003] At present, the stator shell unit in the motor of new energy vehicles mainly relies on the interference to be assembled and fixed to transmit torque. The specific steps are to first heat the shell to make it expand, and then press the stator into the shell, and wait for the stator shell unit to cool down to room temperature. , the fastening is carried ou...
