A high-speed heavy-duty bearing seat

Abstract

The invention discloses a high-speed heavy-duty bearing block which comprises a top cover, a base, two sealing structures, a lubricating oil circulating system and a temperature control oil circulating system. The top cover and the base are arranged from top to bottom and are used for clamping a bearing, the sealing structures are arranged on two sides of the bearing and comprise sealing discs andside covers which are parallelly arranged, the lubricating oil circulating system is used for lubricating the bearing in a circulation manner, and the temperature control oil circulating system is used for continuously controlling the temperatures of a bearing outer ring. The high-speed heavy-duty bearing block has the advantages that good sealing effects can be realized by the high-speed heavy-duty bearing block, the temperatures of the bearing can be effectively controlled, accordingly, radial clearance of the bearing can be controlled, and the bearing can assuredly healthfully and stably run.

Description

technical field [0001] The invention relates to a bearing seat, in particular to a high-speed heavy-duty bearing seat. Background technique [0002] Due to the structural characteristics of rolling bearings, the rollers will rub against the inner and outer rings and release heat during operation, and the temperature difference between the rolling bearing rollers, inner rings and outer rings will be caused by uneven heat generation and divergence. , resulting in different degrees of expansion of the rollers, inner ring and outer ring. Among them, the inner ring has the highest temperature and the most serious expansion, followed by the rollers and the outer ring is the smallest. This will lead to a reduction in the radial clearance of the rolling bearing and an increase in friction. On the other hand, for high-speed and heavy-duty bearing housings, due to the large diameter of the bearing used, the large load bearing capacity, and the high rotational speed, the linear velocit...

AI Technical Summary

Problems solved by technology

On the other hand, for high-speed and heavy-duty bearing housings, due to the large diameter of the bearing used, the large load bearing capacity, and the high rotational speed, the linear velocity at the sealing lip of the existing sealing ring exceeds 25 m / s and cannot achieve effective sealing and cannot meet the ultra-high DN requirements. Therefore, the general sealing ring sealing method is difficult to achieve the ideal sealing effect

For this problem, when the working environment and structure permit, most of the current solutions use gap seals instead of seal rings. However, gap seals have high requirements for parts processing accuracy and installation and debugging, and are difficult to maintain. In actual work, assembly accuracy is limited. Influenced by the environment and the environment, it is easy to cause problems such as lubricating oil leakage and friction, and the actual application effect is not ideal.
