Description
Technical Field
The utility model belongs to the field of bearings, and relates to a deep groove ball bearing with an eccentric stop ring and eccentric resin.
Background
The deep groove ball bearing is one of the most widely used rolling bearings, which features small friction resistance and high rotation speed, and can be used for parts bearing radial load or combined load acted simultaneously in radial and axial directions, and also can be used for parts bearing axial load, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines and tools.
To the tight fit of deep groove ball bearing internal diameter commonly used and the bearing external diameter for transition fit or clearance fit, the bearing external diameter is the problem that is difficult to solve with the current of skidding of dead eye, if the bearing external diameter cooperation is too tight, thereby not only the precision error of dead eye can reflect on the bearing outer race influence the precision, lead to bearing dismouting difficulty moreover, especially the bearing during operation, in the environment of temperature variation, can lead to the bearing to skid, especially the bearing receives temperature variation more showing when adopting the aluminum alloy material.
Disclosure of Invention
The present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a deep groove ball bearing having both an eccentric stopper ring and an eccentric expansion compensation resin, to solve the problems.
The purpose of the utility model can be realized by the following technical scheme: the utility model provides a deep groove ball bearing with eccentric check ring and eccentric resin, includes outer lane, inner circle, ball, holder and shield, the shield be two, and set up respectively in the bearing both sides, outer lane inner wall and inner circle outer wall cooperation form have the cavity that holds the ball, a serial communication port, the holder cover is located on the ball is outer, catch groove and resin annular have been seted up respectively on the outer circumferencial direction of outer lane, the catch groove inside callipers be equipped with the check ring, the resin annular inslot inject and have the expansion compensation resin ring, just catch groove and resin annular tank bottom centre of a circle have the eccentricity with the outer lane centre of a circle, the bellied bellying that makes progress has on the check ring.
In the deep groove ball bearing with the eccentric stop ring and the eccentric resin, the center of a circle of the bottom of the stop groove and the center of a circle of an outer ring have eccentric distances, and the deepest part of the stop groove is consistent with the height of the convex part of the stop ring.
In the above-described deep groove ball bearing having the eccentric snap ring and the eccentric resin, the snap groove width is larger than the snap ring width.
In the above deep groove ball bearing with the eccentric stop ring and the eccentric resin, the outer diameter of the expansion compensation resin ring is larger than the outer diameter of the bearing, the expansion compensation resin ring is fixedly connected with the resin ring groove, and the thickness of the longitudinal section of the expansion compensation resin ring is consistent with the depth of the resin ring groove.
Compared with the prior art, this deep groove ball bearing with eccentric snap ring and eccentric resin, eccentric snap ring and eccentric expansion compensation resin ring have simultaneously, through a bellying has on the snap ring, make deep groove ball bearing be difficult to appear the condition of skidding in operational environment, because the design of bearing external diameter direction has the expansion compensation resin ring, in high temperature process, because the characteristic of expansion resin material, have bigger coefficient of thermal expansion, thereby can avoid the bearing operation phenomenon of skidding to produce, effectually prevent when the unable during operation of snap ring, also can avoid its bearing phenomenon of skidding to appear through the expansion compensation resin.

FIG. 2 is a schematic view of a deep groove ball bearing stop ring with an eccentric stop ring and an eccentric expansion compensating resin ring.
In the figure, 1, outer ring; 2. an inner ring; 3. a ball bearing; 4. a holder; 5. a dust cover; 6. a cavity; 7. a stopper groove; 8. a resin ring groove; 9. an expansion compensation resin ring; 10. a snap ring; 11. a raised portion.
Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the deep groove ball bearing with eccentric stop ring 10 and eccentric resin comprises an outer ring 1, an inner ring 2, balls 3, a retainer 4 and a dust cap 5, wherein two dust caps 5 are respectively arranged at two sides of the bearing, a cavity 6 for accommodating the balls 3 is arranged on the inner wall of the outer ring 1 and the outer wall of the inner ring 2 in a matching manner, the retainer 4 is sleeved on the outer circumference of the balls 3, a stop groove 7 and a resin ring groove 8 are respectively arranged on the outer circumference direction of the outer ring 1, the stop ring 10 is clamped in the stop groove 7, an expansion compensation resin ring 9 is injected in the resin ring groove 8, the center of the groove bottom of the stop groove 7 and the center of the resin ring groove 8 have an eccentric distance with the center of the outer ring 1, a convex part 11 which protrudes outwards is arranged on the stop ring 10, the bearing outer diameter is generally of a metal integral type and can expand and contract with cold under the influence of temperature change, and the stop ring 10 and the expansion compensation resin ring 9 are arranged at the same time, and the stop groove 7 and the resin ring groove 8 are designed eccentrically, because the stop ring 10 is provided with the convex part 11 which protrudes outwards, and the height of the convex part 11 is the same as the deepest depth of the eccentric stop groove 7, when the long-time working condition or the stable influence condition is met, the convex part 11 of the stop ring 10 can rotate along the groove bottom, when the convex part 11 is contacted with the hole wall which is used for installing the bearing, the increasingly tight condition can be generated, the bearing slipping phenomenon is effectively prevented, and the expansion compensation resin has a certain thermal expansion coefficient under the influence of the temperature due to the special reason of the material, so the slipping phenomenon is effectively prevented, meanwhile, the stop ring 10 and the expansion compensation resin ring 9 are designed, so that the deep groove ball bearing has the double-layer anti-slipping effect, and the service life is longer.
