[0002] A bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the so-called bearing seat.

[0003] During the use of the existing bearing seats, due to being exposed to the air for a long time, the sealing performance of the joints of the bearing seats often becomes poor, which will not only cause the internal lubricating oil to leak out, but also cause particles such as dust in the air to enter the inside of the bearing seats, often causing some irreversible damage to the bearing seats, affecting the normal use of the bearing seats, and also reducing the service life of the bearing seats. At the same time, during the use of the bearing seats, due to poor sealing performance, external dust and particles enter the bearing, which will cause problems during the operation of the bearing and increase the noise. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vertical bearing seat to solve the problems of poor sealing performance of the bearing seat, external dust and particles entering the bearing, which will cause problems during the operation of the bearing and increase the noise.

An inner ring is rotatably installed inside the bearing seat body. A ring-shaped ball cavity is formed between the inner side of the bearing seat body and the outer side of the inner ring. Uniformly distributed balls are arranged in the ball cavity. First annular grooves are formed on both sides of the bearing seat body, and second annular grooves matching with the first annular grooves are formed on both sides of the inner ring.

[0006] A first stainless steel ring is sleeved in the first annular groove. The end of the first stainless steel ring extends into the second annular groove, and the end of the first stainless steel ring does not contact the inner ring. An annular rubber sleeve is sleeved on the end of the first stainless steel ring, and the annular rubber sleeve does not contact the inner ring. A second stainless steel ring is sleeved on the outer side of the annular rubber sleeve, and the end of the second stainless steel ring fits against the outer side of the bearing seat body.

[0007] Wherein, a first arc-shaped groove is formed at the center of the inner side of the bearing seat body, and a second arc-shaped groove matching with the first arc-shaped groove is formed at the center of the outer side of the inner ring. The first arc-shaped groove and the second arc-shaped groove form the ball cavity together.

[0008] Wherein, the cross-section of the annular rubber sleeve is U-shaped, and the inner notch of the annular rubber sleeve is sleeved on the end of the first stainless steel ring.

[0009] Wherein, a first rubber ring is provided between the end of the second stainless steel ring and the outer side of the bearing seat body.

[0010] Wherein, an oil injection pipe is provided at the top of the bearing seat body, the oil injection pipe communicates with the ball cavity, and a pipe cap is provided at the end of the oil injection pipe.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model is provided with two-layer mechanical seals of a first stainless steel ring and a second stainless steel ring and two-layer rubber seals of an annular rubber sleeve and a first rubber ring on the outer side of the bearing seat body. There are multiple contact points between the annular rubber sleeve and the first rubber ring and the first stainless steel ring and the second stainless steel ring. When in use, it can prevent external dust and particles from entering the bearing interior. The ball cavity communicates with the oil injection pipe, and with the use of the multi-layer seal structure, the oil can be better retained in the ball cavity, making its sealing and anti-oil leakage effect better. It solves the problem that the bearing operation will be affected and the noise will increase due to external dust and particles entering the bearing interior.
