Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor equipment, in particular to an integrated motor casing. Background Art
[0002] At present, the motor housing and end cover used in the electric rollers in the logistics industry mostly adopt a split design. The front cover has no spline teeth. The housing and end cover are fixed with bolts during assembly. The disadvantage of this assembly method is that it increases the motor materials and manufacturing hours. At the same time, due to the assembly error when the two parts are assembled, the coaxiality between the inside of the housing and the front bearing chamber increases, and the motor vibrates and the noise increases when it rotates. The front cover has spline teeth and is fixed to the reducer by bolts during assembly, which reduces the torsional strength of the reducer and the motor.
[0003] In view of this, we propose an integrated motor housing to solve the existing problems. Utility Model Content
[0004] The purpose of the utility model is to provide an integrated motor housing to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated motor casing, including a shell, the shell is an integrated structure, the outer ring of the front end of the shell is provided with spline teeth for cooperating with the gear box, and the spline teeth are provided with a V-groove near the front end surface of the shell.
[0006] Preferably, a limiting boss is provided inside the shell, and a process groove is provided between the limiting boss and the shell wall.
[0007] Preferably, a bearing chamber is provided at the center of one side of the front end of the housing.
[0008] Preferably, a retaining ring groove is provided at the front end of the bearing chamber.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts an integrated motor housing structure, which reduces the difficulty of installing the retaining spring during mass production and can be extruded in one step, thereby reducing the materials required for producing the motor and shortening the manufacturing and assembly time.
