Abstract
The utility model discloses a sealed deep groove ball bearing which comprises bearing inner rings, bearing outer rings and roll balls arranged between the bearing inner rings and the bearing outer rings. Maintainers used to limit the roll balls are arranged between the bearing inner rings and the bearing outer rings. Opposite circumferential faces of each bearing inner ring and each bearing outer ring are both provided with annular raceways used for placing of the roll balls. Annular protruding arrises are arranged on two sides of each annular raceway on each bearing inner ring and two sides of each annular raceway on each bearing outer ring. Elastic seal check rings are clamped between the annular protruding arrises on each bearing inner ring and each bearing outer ring. The sealed deep groove ball bearing is simple in structure, low in production cost, stable in performance, convenient to install and use, and good in sealing effect due to the fact that the seal check rings cannot fall off easily after being used for a long time. Besides, dust can be effectively prevented from entering the deep groove ball bearing, dismounting and installing of the seal check rings are enabled to be more convenient and faster due to the fact that an elastic clamping method is adopted, and therefore operation efficiency of the deep groove ball bearing is improved and service life is prolonged.
Description
Technical field
The utility model relates to the ball bearing field, is specially a kind of sealed type deep groove ball bearing.
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.
The model utility content
The purpose of this utility model provides a kind of sealed type deep groove ball bearing, sealing configuration cost of production with deep groove ball bearing traditional in the solution prior art is higher, sealing cover easily comes off, sealing effect is not good, complex structure, unstable properties, and then affect 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 deep groove ball bearing, 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: the ring raceway both sides on described bearing inner race, the bearing outer ring are equipped with annular ridge, are installed with the elastic packing back-up ring between the annular ridge on described bearing inner race, the bearing outer ring.
Described a kind of sealed type deep groove ball bearing is characterized in that: described elastic packing back-up ring is towards the one side of the spin camber curved surface that caves inward.
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, long-time also difficult drop-off of rear Sealing shield ring, the good sealing effect of using, can prevent effectively that dust from entering deep groove ball bearing inside, and the mode that adopts elasticity to clamp so that the dismounting of Sealing shield ring is more convenient, has promoted operational efficiency and the working life of deep groove ball bearing.
