Embodiment 1

[0026] see Figure 1-2 , is a structural schematic diagram of the motor end cover provided by the present invention.

[0027] The invention discloses a motor end cover, which comprises an end cover outer ring 1 and an end cover inner ring 2, wherein the end cover inner ring 2 is arranged inside the end cover outer ring 1, and the end cover outer ring 1 is provided with a Seat connection 3, the end cover inner ring 2 is provided with a bearing seat, the bearing seat is used to install the bearing unit 4, and also includes a connecting rib 5 arranged between the end cover inner ring 2 and the end cover outer ring 1.

[0028] In the motor end cover provided by the present invention, the outer ring 1 of the end cover of the motor end cover is connected to the motor frame through the seam 3 thereon, and the bearing inner ring 2 is equipped with a bearing seat and a bearing unit 4 . Since the connecting ribs 5 are arranged between the inner ring 2 of the end cover and the outer rin...

Embodiment 2

[0030] In another embodiment provided by the present invention, the motor end cover in this embodiment is similar in structure to the motor end cover in Embodiment 1, and the similarities will not be repeated, and only the differences will be introduced.

[0031] In this embodiment, it is specifically disclosed that the connecting rib 5 is an integral rib, and the form of the integral rib increases the overall radial stiffness of the motor end cover.

[0032] In order to further increase the strength and rigidity of the motor end cover, the present invention also discloses that the motor end cover further includes a plurality of first auxiliary ribs 6 arranged on the connecting ribs 5 .

[0033] In order to facilitate the installation of the sensor, the invention discloses that in the motor end cover, a notch 7 for installing the sensor is also provided on the outer ring 1 of the end cover.

[0034] Mainly considering that the notch 7 for installing the sensor is provided on t...

Embodiment 3

[0036] In the third embodiment provided by the present invention, the motor end cover in this embodiment is similar in structure to the motor end cover in the second embodiment, so the similarities will not be repeated, and only the differences will be introduced.

[0037] In this embodiment, the present invention discloses that the connecting rib 5 is a spoke-type rib, so that the strength and rigidity of the motor end cover are uniform.

[0038] Further, specifically, in this embodiment, the number of the first connecting ribs is 7, and the number of the second auxiliary ribs 8 is 2 as an example.

[0039] It should be noted that the connecting ribs 5, the first auxiliary ribs 6 and the second auxiliary ribs 8 are only connecting ribs in a broad sense, and the implementation items in this example also include modifications made on this basis, that is, the inner ring The area and the outer ring area are connected by radial connecting ribs 5, and the connecting ribs 5 are dive...

Abstract

The invention discloses a motor end cap and a motor. The motor end cap includes an end cap outer ring and end cap inner ring, wherein the inner ring of the end cap is arranged inside the outer ring of the end cap; the outer ring of the end cap is provided with a spigot which is connected with a motor base; and the inner ring of the end cap is provided with a bearing seat for installation of a bearing unit. The motor end cap also includes a joint bar plate arranged between the inner ring of the end cap and the outer ring of the end cap. According to the motor end cap provided by the invention, the outer ring of the motor end cap is connected with the motor base through the spigot arranged in the outer ring; and the bearing seat is installed on the inner ring of the bearing so as to enable installation of the bearing unit. Since the joint bar plate is arranged between the inner ring of the end cap and the outer ring of the end cap, the intensity and the rigidity of the motor end cap are raised; and joint strength with high intensity and high reliability of the motor end cap can be realized.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a motor end cover and a motor. Background technique [0002] With the development of traction motors in the direction of high speed and heavy load, the performance requirements of each component of the motor are getting higher and higher. As the main load-bearing component, the motor end cover needs to have sufficient strength and rigidity in a limited space. Current motor endshields often suffer from insufficient strength and rigidity. [0003] Therefore, how to improve the strength and rigidity of the motor end cover in a limited space is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the first object of the present invention is to provide a motor end cover to improve the strength and rigidity of the motor end cover. [0005] A second object of the present invention is to provide a motor. ...
