However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a large motor drive end oil supply bearing sleeve, including a bearing sleeve 1. Side grooves 9 are provided on both sides of the middle part of one side of the bearing sleeve 1. A second threaded hole 3 is provided on one side of the side groove 9, which penetrates the bearing sleeve 1. An oil passage hole 4 is provided on one side of the bearing sleeve 1, which communicates with the second threaded hole 3. A first threaded hole 2 is provided through the outer edge of the bearing sleeve 1. A second through hole 13 and a first through hole 10 are provided through the inner edge of the bearing sleeve 1. A third threaded hole 6 is provided on the outer surface of the bearing sleeve 1.

[0022] The specific settings and functions of this embodiment are described in detail below. By setting the No. 2 threaded hole 3 and the oil passage hole 4, grease can enter the oil groove on the outer surface of the double-row roller self-aligning bearing during oiling. This allows the grease to enter the interior of the double-row roller self-aligning bearing, ensuring that grease can enter both rows of rollers and the raceway. This can better guarantee the bearing lubrication effect, improve the service life of the bearing and the reliability of the equipment.

A spring 12 is fixedly connected between the lower end of the stop bar 8 and the inner wall of the sleeve 5.

[0024] The overall effect of this embodiment is that, through the setting of sleeve 5 and limiting collar 7, when installing the double-row roller self-aligning bearing and bearing sleeve 1, sleeve 5 is first inserted into the second through hole 13. The stop rod 8 guides the position during bearing installation. When one side of the bearing contacts the stop rod 8, it is in place. Moreover, the stop rod 8 adopts a rotating connection, which will not cause wear to the bearing, making it more practical. After the bearing and bearing sleeve 1 are installed, the stop rod 8 is rotated to pull sleeve 5 out of the second through hole 13.

[0025] The usage and working principle of this device are as follows: During installation, move the stop lever 8 and insert both the stop lever 8 and the sleeve 5 into the second through hole 13 until the limiting collar 7 contacts the bearing sleeve 1. Through the elasticity of the spring 12, the stop lever 8 rotates to a position perpendicular to the sleeve 5. Then, install the double-row roller self-aligning bearing with the bearing sleeve 1 until one end of the bearing contacts the stop lever 8, thus completing the installation of the bearing and the bearing sleeve 1. The second threaded hole 3 is connected to the oil filling groove on the outer surface of the bearing. Then, pull the sleeve 5 out of the second through hole 13. Next, connect the inner ring of the bearing to the output end of the motor, connect the first threaded hole 2 to the blower, and connect the second threaded hole 3 to the oil filling pipe. Finally, connect the blower to the coal processing furnace.
