[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 2 The utility model provides an easy-to-install motor end cover, including an end cover 1, a center hole 2 is provided at the center position of the end cover 1, a limiting ring 3 is provided on the inner side of the end cover 1 at the position of the center hole 2, a bearing sleeve 4 is integrally connected to the limiting ring 3, a heat dissipation port 5 is provided on the inner wall of the bearing sleeve 4 around the axis, and a heat dissipation hole 6 is provided at the position of the heat dissipation port 5.

[0027] Specifically, Figure 1 As shown, the outer wall of the limiting ring 3 and the bearing sleeve 4 are arranged flush, and there is a spacing difference between the inner wall of the bearing sleeve 4 and the inner wall of the limiting ring 3, and the position of the spacing difference can block the bearing.

[0028] Specifically, the arc length of the heat dissipation opening 5 is one twentieth of the circumference of the bearing sleeve 4 , and the number of the heat dissipation openings 5 ​​is 3-6, so as to avoid the heat dissipation openings 5 ​​occupying too much space and affecting the stability of the bearing installation.

[0029] Specifically, Figure 1 and Figure 2 As shown, an arc-shaped guide surface is provided at the opening of the bearing sleeve 4 to facilitate the alignment of the bearing with the bearing sleeve 4.

[0030] Working principle:

[0031] Align the bearing sleeve 4 of the end cover 1 with the bearing. Because an arc-shaped guide surface is provided at the edge of the bearing sleeve 4, the arc-shaped guide surface will allow the bearing to slightly enter the opening position of the bearing sleeve 4, so that the alignment is more accurate. Then put the cover at the position of the center hole 2, knock the cover, and knock the end cover 1 down. In this way, the bearing enters the bearing sleeve 4 and stops when the bearing contacts the limit ring 3. Due to the opening of the heat dissipation port 5, the contact area between the bearing sleeve 4 and the outer surface of the bearing is reduced, the movement resistance is reduced, and the positions of the heat dissipation port 5 and the heat dissipation hole 6 are convenient for the heat dissipation of the bearing.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
