Embodiment

[0040] A combined linear motor end cover, such as Figure 1 to Figure 5 as shown,

[0041] Including end cover body 41, sliding sleeve 6 and limit ring 42;

[0042] The sliding sleeve 6 is arranged in the end cover body 41, the sliding sleeve 6 is slidably connected with the mover 2 and supports the mover 2, and the limit ring 42 is arranged in the end cover body 41 close to the motor body 1 side, used to limit the travel of mover 2.

[0043] The combined linear motor end cover provided by the embodiment of the present invention not only has the functions of dustproof and protection, but also supports the operation of the mover 2 by setting the sliding sleeve 6 for the mover 2 to slide, and the limit ring 42 can The mover 2 is limited, and no additional limit mechanism is required, which can simplify the overall structure of the tubular linear motor and reduce the volume of the linear motor, so that the linear motor can be applied to occasions that require relatively strict ...

Abstract

The embodiment of the invention belongs to the technical field of motors, and relates to a combined linear motor end cover. According to the technical scheme, the end cover comprises an end cover body, a sliding sleeve and a limiting ring; wherein the sliding sleeve is arranged in the end cover body, the sliding sleeve is slidably connected with a rotor and supports the rotor, the limiting ring isarranged on the side, close to the motor body, of the end cover body and used for limiting the stroke of the rotor, the dustproof and protection effects are achieved, the sliding sleeve is arranged to allow the rotor to slide, and operation of the rotor is supported. And the limiting ring can limit the rotor, so that the overall structure of the tubular linear motor can be simplified, the size ofthe linear motor can be reduced, the space occupied by the internal structure of the linear motor is well reduced, the internal structure of the motor is greatly optimized, the cost of the motor is reduced, and the manufacturing and maintenance are simpler and more convenient.

Description

technical field [0001] The present application relates to the technical field of motors, and more specifically, to a combined linear motor end cover. Background technique [0002] Linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and developed into a plane. The side evolved from the stator is called the primary, and the side evolved from the rotor is called the secondary. In practice, the primary and secondary are manufactured to different lengths to ensure that the coupling between the primary and secondary remains constant over the required travel range. Linear motors can be short primary and long secondary, or long primary and short secondary. Considering the manufacturing cost and operating cost, take the linear induction motor as an example: when the primary winding is connected to the AC power supply, a ...
