Detailed Description

The present invention will be further described with reference to the following examples.

Examples

A motor as shown in fig. 1-3, which includes a motor body 1, the motor body 1 includes a housing, a stator and a rotor, which are not described in detail in the prior art, the housing includes a cylinder 13, and an end cover 11 and a bottom cover 12 disposed at two ends of the cylinder 13, wherein the end of the motor shaft 14 extending out is defined as the end cover 11, it is noted that a positioning portion 111 for positioning a gear is disposed on the end cover 11, and a corresponding gear or a gear shaft is inserted into the positioning portion 111 for positioning when the motor is installed. The positioning portion 111 is a circular hole.

In this embodiment, the positioning portion 111 is a protrusion protruding from the end cover 11, and a circular hole is processed on the protrusion; the positioning part 111 can be designed to be a round hole which is concave to the end cover 11 according to requirements, the thickness of the end cover 11 is only required to be thickened, and the round hole is machined in the surface of the end cover 11.

In this embodiment, the motor shaft 14 penetrates the end cover 11, so that the motor shaft 14 does not shake, a bearing is disposed between the motor shaft 14 and the end cover 11, a bearing mounting portion 113 for mounting the bearing is disposed on one side of the end cover 11 facing the inside of the motor body 1, and a bearing is disposed between the other end of the motor shaft 14 and the bottom cover 12, so that noise reduction during rotation of the motor shaft 14 can be ensured, and shaking of the motor shaft 14 can be prevented. In this embodiment, the end cover 11 and the bottom cover 12 of the motor body 1 are fixed by screws, and the cylinder 13 is clamped between the bottom cover 12 and the end cover 11. In this embodiment, the inner side of the end cap is provided with a slot 114 for the barrel to be inserted into, and the barrel can be inserted into the slot to form a positioning function, so as to ensure that the motor shaft is located at the axis position of the barrel.

In order to facilitate the installation of the motor main body 1, the end cover 11 of the present embodiment is provided with an installation hole 112 for fixing the motor main body 1 to the device connected thereto. In this embodiment, the outer side of the end cap 11 is provided with a connecting portion extending outward, and the mounting hole 112 is formed on the connecting portion.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
