Problems solved by technology

However, this assembly method will result in a large number of fasteners in the motor, and it will be more troublesome to assemble.
Moreover, when the motor shaft is installed in a conventional way, the bearings at both ends of the motor shaft also need to consider the reserved axial clearance of the bearings, which will also make the entire assembly process more complicated and increase the cost

Abstract

The invention discloses a motor, which comprises a motor outer shell, a motor shaft, a split type sliding upper bearing, a stator, a mover, and a sliding lower bearing, wherein the motor outer shell has an accommodating cavity; the motor shaft has a first end and a second end which are opposite; a circle of ring groove is formed in a position adjacent to the first end on the motor shaft; a first column body and a second column body are sequentially formed at positions from the ring groove to the second end of the motor shaft, and a first step groove is formed in a position where the two columnbodies are connected; the split type sliding upper bearing is in clearance fit with the ring groove, and is configured to be fixed on the motor outer shell when the motor shaft is inserted into the accommodating cavity, so as to fix the first end of the motor shaft; the stator is fixed in the accommodating cavity, and the mover rotates relative to the stator and is fixed on the first column body;and the sliding lower bearing is fixed to the bottom part of the motor outer shell, the second column body of the motor shaft extends into a bearing hole of the sliding lower bearing, and the secondcolumn body is in clearance fit with the bearing hole; and the first step groove of the motor shaft is born on the end surface of the sliding lower bearing, so as to position the second end of the motor shaft.

Description

technical field [0001] The present invention relates to the technical field of motors, and more specifically, the present invention relates to a plug-in motor. Background technique [0002] Motor, also known as motor, specifically refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The main job of the motor is to generate driving torque, which is used as a power source for various electrical equipment or various mechanical devices. With the continuous development of motor technology, motors have been widely used in various industries. [0003] However, in a conventional motor, fasteners, such as screws, bolts, etc., are usually used to fix and connect multiple axial parts of the motor in series. However, such an assembly method will cause a large number of fasteners in the motor, and the assembly is also troublesome. Moreover, when the motor shaft is installed in a conventional manner, the bea...
