Description

A Deep Groove Ball Bearing with Lubricating Oil Groove

technical field

The utility model relates to a deep groove ball bearing with a lubricating oil groove, which is suitable for the field of display screens.

Background technique

Ball bearings are a type of rolling bearings, which are mainly composed of four basic components: balls, inner rings, outer rings and cages. The balls are installed in the middle of the inner ring and outer ring, which can bear a large load. Deep groove ball bearings mainly bear radial loads, and can also bear radial loads and axial loads at the same time. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The friction coefficient of the deep groove ball bearing is small, and the limit speed is also high. At present, the lubrication effect of deep groove ball bearings is not good, and the excess lubricating oil on the balls cannot be effectively used, and they are prone to wear in a long-term high-speed working environment, which in turn affects the operating efficiency and service life of deep groove ball bearings .

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a deep groove ball bearing with a lubricating oil groove, including an outer ring, an inner ring, steel balls, a cage and a dust cover, and the steel balls are set inside the cage In the middle of the outer ring and the outer ring, the dust cover is arranged between the inner ring and the outer ring on both sides of the steel ball, an oil storage tank is arranged on the inner side of the outer ring, and an annular spring is arranged on both sides of the oil storage tank. The inner side of the annular spring is provided with pressing pieces, and the space between the pressing pieces is filled with lubricating oil. The oil storage tank is provided with a plurality of oil outlets on the inner wall of the outer ring, and the oil outlets are arranged at the point where the steel ball contacts the inner wall of the outer ring Location.

Further, in order to prevent leakage of lubricating oil, a sealing ring is provided inside the dust-proof cover.

Further, in order to better fix the position of the steel balls and prevent offset, the cages between adjacent steel balls are fixed by rivets.

Further, in order to prevent dust from entering into the bearing, an annular groove is provided on the inner side of the outer ring, and one end of the dust-proof cover is snapped into the annular groove.

Further, in order to increase the sealing performance of the dust cover, an O-ring is arranged in the middle of the other end of the dust cover.

After adopting the above technical scheme, the utility model has the following beneficial effects: the utility model is provided with an oil storage tank, which can store lubricating oil in the oil storage tank, and the two ends of the oil storage tank are provided with ring springs, and the ring springs There is a pressure piece on the inner side, which can control the outflow of lubricating oil through the elastic force of the spring, the rotating pressure of the steel ball and the oil pressure of the oil outlet, and replenish oil to the bearing in time to avoid the phenomenon of bearing wear and improve the operation of the bearing. efficiency and prolong the service life of the bearing.

detailed description

In order to make the content of the utility model more clearly understood, the utility model will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

As shown in Figure 1-3, a deep groove ball bearing with a lubricating oil groove includes an outer ring 1, an inner ring 2, a steel ball 3, a cage 4 and a dust cover 5, and the steel ball 3 is set on the In the middle of the inner ring 2 and the outer ring 1, the dust cover 5 is arranged between the inner ring 2 and the outer ring 1 on both sides of the steel ball 3, and the inner side of the outer ring 1 is provided with an oil storage tank 6, and the oil storage tank 6 Ring springs 7 are arranged on both sides of the ring spring 7, and pressure pieces 8 are arranged on the inner side of the ring spring 7, and lubricating oil 9 is filled between the pressure pieces 8, and the oil storage tank 6 is provided with a plurality of outlets on the inner wall of the outer ring 1. The oil port 10 is set at the position where the steel ball 3 is in contact with the inner wall of the outer ring 1 .

In order to prevent the lubricating oil 9 from leaking out, a sealing ring 11 is provided inside the dustproof cover 5 .

In order to better fix the position of the steel balls 3 and prevent offset, the cages 4 between adjacent steel balls 3 are fixed by rivets 12 .

In order to prevent dust from entering the inside of the bearing, an annular groove 13 is provided on the inner side of the outer ring 1 , and one end of the dustproof cover 5 is snapped into the annular groove 13 .

In order to increase the sealing performance of the dust-proof cover 5 , an O-ring 14 is arranged in the middle of the other end of the dust-proof cover 5 .
