Circular-ring-shaped groove even oil supplying structure vertically provided with rolling bearings

Abstract

The invention relates to a circular-ring-shaped groove even oil supplying structure vertically provided with rolling bearings. The circular-ring-shaped groove even oil supplying structure is providedwith a set of rolling bearings installed in a bearing seat, and an oil supply opening located above the rolling bearings. A circular-ring-shaped oil storage structure is arranged between the rolling bearings and the oil supply opening. Lubricating oil discharged from the oil supply opening is fully charged into the circular-ring-shaped oil storage structure firstly and overflows onto the rolling bearings. By means of the circular-ring-shaped groove even oil supplying structure vertically provided with the rolling bearings, compared with an existing direct single-side oil spraying manner of a conventional spray pipe, lubricating oil discharged from an oil supply pipe is charged into the circular-ring-shaped groove firstly and overflows onto the rolling bearings, and relatively even coolingand lubricating of a whole roller path can be achieved.

Description

technical field [0001] The invention relates to a rotary machine shaft system, in particular to an oil supply structure for vertically installed rolling bearings in the rotary machine shaft system. Background technique [0002] Many rotating machinery shaft systems use rolling bearings as supporting bearings. When the operating speed of the equipment is high, the rolling bearings are often lubricated and cooled by oil spraying. For horizontal equipment, the setting of the position of the oil injection pipe is more important. Generally, it should be set on the upper part of the bearing. With the rotation of the bearing and the action of gravity, the lubricating oil can reach the entire raceway of the bearing to achieve the effect of cooling and lubricating the bearing. [0003] For vertical equipment, due to the details of the design of the oil injection method, it is easy to cause poor lubrication and cooling effects, reduce the service life of the rolling bearing, or even f...

AI Technical Summary

Problems solved by technology

To solve the direct one-side oil injection method of the nozzle, when used on the rotor of vertical rotary machinery, it can only cool and lubricate part of the raceway well, and the cooling and lubrication effect on other parts of the raceway is not good or can not be achieved. The problem of cooling and lubricating effect
