Abstract
The utility model discloses a sealed deep groove ball bearing with oil storage tanks. The sealed deep groove ball bearing with the oil storage tanks comprises inner bearing rings, outer bearing rings, balls and retainers, wherein annular rolling paths are arranged on the opposite circumferences of the inner bearing rings and the outer bearing rings; contact faces of the inner bearing rings, the outer bearing rings and the retainers are provided with a plurality of strip-shaped oil storage tanks which are axially arranged at equal intervals; a plurality of strip-shaped oil storage tanks communicate with the annular rolling paths; annular beads are arranged on two sides of the oil storage tanks of the inner bearing rings and the outer bearing rings; and elastic sealing retainer rings are clamped between the annular beads on the inner bearing rings and the outer bearing rings. The sealed deep groove ball bearing with the oil storage tanks is simple in structure and low in production cost; the sealing retainer rings are difficult to fall off after long time use, so that the sealing effect is good; by the design that the oil storage tanks are additionally arranged on the bearing inner rings and the bearing outer rings, lubricity of the ball rolling is ensured, the balls and the bearing inner and outer rings are prevented from abrading, and the running efficiency of the deep groove ball bearing is effectively improved, and service life of the deep groove ball bearing is effectively prolonged.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing, is specially a kind of sealed type with the deep groove ball bearing of oil storage tank.
Background technique
Ball bearing is a kind of of rolling bearing, mainly is to be made of four primary elements: ball, inner ring, outer ring and retainer.Ball is installed in the centre of interior ring and outer shroud, can bear larger load.Deep groove ball bearing mainly bears radial load, also can bear simultaneously radial load and thrust load.When it only bore radial load, wrapping angle was zero.When deep groove ball bearing has larger radial internal clearance, have the performance of angular contact bearing, can bear larger thrust load, the friction factor of deep groove ball bearing is very little, and limit speed is also very high.At present, the sealing configuration of deep groove ball bearing exists cost of production higher, and sealing cover easily comes off, sealing effect is not good, and the problems such as complex structure, unstable properties affect operational efficiency and the working life of deep groove ball bearing; And the lubrication effect of deep groove ball bearing is not good, and unnecessary lubricant oil can not get effectively utilizing on the ball, and is easily frayed under long-time high-revolving working environment, and then affects operational efficiency and the working life of deep groove ball bearing.
The model utility content
The purpose of this utility model provides a kind of sealed type with the deep groove ball bearing of oil storage tank, traditional deep groove ball bearing sealing cover easily comes off in the prior art to solve, sealing effect is not good, and lubrication effect is not good, unnecessary lubricant oil can not get effectively utilizing on the ball, affects the operational efficiency of deep groove ball bearing and the problem in working life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sealed type is with the deep groove ball bearing of oil storage tank, include bearing inner race, bearing outer ring and be arranged on bearing inner race and bearing outer ring between ball, be provided with the retainer for spacing ball between described bearing inner race and the bearing outer ring, be equipped with on the relative circumferential surface of described bearing inner race and bearing outer ring for the ring raceway of settling ball, it is characterized in that: described bearing inner race, equidistantly be axially arranged with respectively several bar shaped oil storage tanks on the surface of contact of bearing outer ring and retainer, described several bar shaped oil storage tanks all are communicated with ring raceway, described bearing inner race, oil storage tank both sides on the bearing outer ring are equipped with annular ridge, described bearing inner race, be installed with the elastic packing back-up ring between the annular ridge on the bearing outer ring.
Described a kind of sealed type is characterized in that with the deep groove ball bearing of oil storage tank: described retainer is two halves formula structure, and passes through rivet.
The beneficial effects of the utility model are:
The utility model is simple in structure, cost of production is low, stable performance, easy to install, the long-time also difficult drop-off of rear Sealing shield ring that uses, good sealing effect can prevent effectively that dust from entering deep groove ball bearing inside, and the mode that adopts elasticity to clamp is so that the dismounting of Sealing shield ring is more convenient; And the utility model adopts the design of setting up oil storage tank at bearing inner race and bearing outer ring, unnecessary lubricant oil is stored in the oil storage tank, lubricant oil when deep groove ball bearing runs up for a long time in the oil storage tank can be to repairing in the ring raceway, with the lubricity that guarantees that ball rolls, avoid the inside and outside circle of ball and bearing frayed, effectively promoted operational efficiency and the working life of deep groove ball bearing.
