Deep groove ball bearing provided with lubrication oil hole

Abstract

The invention discloses a deep groove ball bearing provided with a lubrication oil hole. The deep groove ball bearing comprises an inner ring 02 and an outer ring 01 which are sleeved concentrically inside and outside. Steel balls 04 are fixed between the inner ring 02 and the outer ring 01 through a cage. The cage comprises a cage cover 16 and a cage base 06 which are riveted by rivets 09. The middle part of the outer cylindrical surface of the outer ring is provided with a through oil hole vertically leading to the steel balls. The oil hole faces right towards the center of the steel balls. An oil groove and the oil hole are disposed in the outer ring, and the oil and grease can enter into the inside of the bearing during the motion process of the bearing and plays a role of lubricating the bearing, and therefore the service lifetime of the bearing is prolonged, a machine is not needed to be stopped due to addition of lubricating oil, and the working efficiency is increased. Impurities are liable to enter into the bearing during working, and once the impurities enter, rotation and the service lifetime of the bearing are largely influenced. By addition of the oil groove and the oil hole, the impurities are liable to flow out from the oil hole, thus prolonging the service lifetime of the bearing and guaranteeing the rotation.

Description

technical field [0001] The invention relates to the technical field of bearings. Background technique [0002] The structure of deep groove ball bearings is as follows: figure 1 As shown, it includes an inner ring 02 and an outer ring 01 that are concentrically socketed inside and outside, and a steel ball 04 is fixed between the inner ring 02 and the outer ring 01 by a cage, and the cage includes a cage bolted by a rivet 09 Cover 16 holds frame mount 06 . [0003] Deep groove ball bearings are generally installed in places with high rotational speeds. The problem is that sufficient lubricating oil must be provided to the deep groove balls in an environment with high rotational speeds. If sufficient lubricating oil is not provided, it is easy to cause the temperature of the bearing to rise, accelerate the aging of the oil, and reduce the service life of the bearing. In general, because deep groove ball bearings are relatively closed, it is difficult to provide sufficient ...

AI Technical Summary

Problems solved by technology

If sufficient lubricating oil is not provided, it is easy to cause the temperature of the bearing to rise, accelerate the aging of the oil, and reduce the service life of the bearing

In general, because deep groove ball bearings are relatively closed, it is difficult to provide sufficient lubricating oil to the bearings during motion.

Moreover, if the machine is stopped to add lubricating oil, not only loading and unloading will be troublesome and time-consuming, but also the bearings will be easily damaged.
