Problems solved by technology

At present, there is only one oiling hole in the outer ring of this type of bearing, which is located on the side of the outer ring, and the oiling and lubrication effect of the bearing is poor.
After the bearing has been used in continuous high-speed operation for a period of time, the grease cannot be replenished into the two grooves effectively and evenly, and even the groove far away from the oil hole cannot be replenished with lubricating oil, resulting in rapid wear of the bearing and increased noise. And the unstable rotation causes the surface to overheat and burn out, reducing the service life

Embodiment Construction

[0013] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1 to Figure 2 As shown, the present invention includes an outer ring 1, the inner two ends of the outer ring 1 are equipped with a cage 3, the cage 3 is matched with the ball 2, and the ball 2 is located in the annular groove on the mandrel 11; There are first oil filling holes 12 and steps near the cage 3 respectively. The first oil filling holes 12 are closed by the filling plug head 10, which can prevent the lubricating oil inside the bearing from leaking and foreign impurities from entering the inside of the bearing. The steps are formed by the first step 5 and the second step 6, the first step 5 has a second oil filling hole 8, preferably, the diameter of the outer circle of the first step 5 is Φ14~Φ22mm, and the width is 1~20mm, the outer circle of the second step 6 The diameter is Φ18~Φ22mm, the width is 1~10...

Abstract

The invention relates to a novel revolving cup bearing which comprises an outer ring. Retainers are arranged at the two ends inside the outer ring, the retainers are matched with balls, and the balls are located in annular grooves in a central spindle. The positions, close to the retainers, of the outer circles at the two ends of the outer ring are respectively provided with a first oil filling hole and a step, the first oil filling holes are sealed by oil filling chock plugs, the steps are formed by first steps and second steps, second oil filling holes are formed in the first steps, T-shaped concave grooves are formed in the adjacent positions of the first steps and the second steps in the second steps, oil filling rings are arranged in the first steps in a sleeved mode, T-shaped convex blocks are arranged on the edges of the oil filling rings, and the convex blocks are embedded into the T-shaped concave grooves. The novel revolving cup bearing is simple in structure, the bearing can be lubricated well, the service life of the bearing can be prolonged, and the production cost of enterprises can be lowered.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a rotor bearing used on a rotor spinning machine. Background technique [0002] The rotor bearing used on the rotor spinning machine is mainly composed of an outer ring, a mandrel, a cage, a rolling element (roller or ball), a dustproof ring, a positioning ring, etc. At present, there is only one oiling hole in the outer ring of this type of bearing, which is located on one side of the outer ring, and the oiling and lubrication effect of the bearing is poor. After the bearing has been used in continuous high-speed operation for a period of time, the grease cannot be replenished into the two grooves effectively and evenly, and even the groove far away from the oil hole cannot be replenished with lubricating oil, resulting in rapid wear of the bearing and increased noise. And the unstable rotation causes the surface to overheat and burn out, reducing the service life. Contents ...
