Problems solved by technology

[0002] The active joints of coal shearers are mostly connected with the actuator through the transmission shaft at present. The shaft sleeve set on the transmission shaft plays a role in protecting and guaranteeing the normal use and service life of the transmission shaft. The gap between the shaft sleeve and the transmission shaft is generally It is used to add butter and other similar lubricating oils between its contact surfaces. It is necessary to constantly check and replenish butter in a timely manner. In the case of a large amount of engineering, it needs to be added frequently, and the contact surface needs to be cleaned when adding new lubricating oil. , is relatively cumbersome, and the maintenance work is relatively arduous, and frequent maintenance will inevitably affect the speed of coal mining, which in turn will affect the efficiency of the enterprise

Embodiment Construction

[0020] In order to increase the lubrication time between the bushing and the drive shaft, reduce the maintenance frequency, and increase the working speed and workload, this embodiment provides a method such as figure 1 , 2 The shaft sleeve used for the rocker arm of the coal shearer shown in .

[0021] like figure 2 As shown, the groove 3 extends along the axial direction of the inner wall 2 .

[0022] like image 3 As shown, the groove 3 can also extend along the circumference of the inner wall 2 .

[0023] In order to ensure uniform lubrication, the grooves 3 are uniformly arranged on the inner wall 2 .

[0024] Furthermore, in order to improve maintenance efficiency, such as Figure 4 As shown, a filling hole 4 for filling lubricant can be opened on the outer wall 1 of the sleeve, which communicates with the groove 3 on the inner wall 2, and a plurality of filling holes can be evenly arranged along the groove 3, so that, Lubricant filling can be achieved without dis...

Abstract

For increasing the timing length of lubrication between a shaft sleeve and a transmission shaft, minimizing the frequency of the maintenance, and raising the operation speed and workload, the present invention provides a design method of the shaft sleeve used for a rocker arm of a coal mining machine, the design is characterized by comprising an external wall and an internal wall, a groove used for storing a lubricant is provided on the external wall. The design that the groove used for storing the lubricant (like a solid lubricant) which is provided on the internal wall of the shaft sleeve is capable of increasing the filling amount of the lubricant, prolonging the lubrication timing length, raising the uniformity of the lubrication, reducing the maintenance frequency, and raising the operation speed and workload.

Description

technical field [0001] The invention relates to a design method of a shaft sleeve used for a rocker arm of a coal mining machine. Background technique [0002] The active joints of coal shearers are mostly connected with the actuator through the transmission shaft at present. The shaft sleeve set on the transmission shaft plays a role in protecting and guaranteeing the normal use and service life of the transmission shaft. The gap between the shaft sleeve and the transmission shaft is generally It is used to add butter and other similar lubricating oils between its contact surfaces. It is necessary to constantly check and replenish butter in a timely manner. In the case of a large amount of engineering, it needs to be added frequently, and the contact surface needs to be cleaned when adding new lubricating oil. , is relatively cumbersome, and the maintenance work is relatively arduous for this reason, and frequent maintenance will inevitably affect the speed of coal mining, ...
