Abstract
The utility model discloses a bearing. The bearing comprises a bearing outer ring and a bearing inner ring, wherein rolling balls are arranged between the bearing outer ring and the bearing inner ring, a lubrication passage is formed in the bearing inner ring along the radial direction, a lubrication hole is formed in the bearing inner ring along the axial direction, the lubrication hole is connected with the lubrication passage, a hollow cavity is formed inside each rolling ball, a hole passage is formed in each rolling ball, so as to connect the corresponding hollow cavity and the outer side of the corresponding rolling ball, and sponge is arranged in the hollow cavities and is adsorbed with lubricating grease. According to the bearing, the hollow cavities are formed inside the rolling balls, so that the bearing has a certain deformation room when the bearing is subjected to impact, and thus, the bearing can be prevented from being stuck; meanwhile, the sponge is arranged in the bearing and is adsorbed with the lubricating grease, so that when the rolling balls are subjected to deformation, the sponge is squeezed due to the deformation of the rolling balls, then, the lubricating grease in the sponge is squeezed out of the hole passages and plays a role in lubricating the rolling balls, and thus, the anti-sticking effect of the bearing is better.
Description
Technical field
The utility model relates to machinery manufacturing technology field, specifically a kind of bearing.
Background technique
Along with the development of modern technologies, most bearing all comprises the ball between bearing inner race and outer shroud, as notification number a kind of bearing that is CN203248536U, comprise outer race and bearing inner ring, between described outer race and bearing inner ring, be provided with ball, this bearing inner ring is radially provided with at least one lubricated road, bearing inner ring is provided with at least one lubrication hole vertically, this lubrication hole is connected with lubricated road, described ball is hollow-core construction, thereby this patent adopts hollow ball to reduce weight and the thermal capacitance of ball self, and because hollow-core construction can be born certain deformation, prevent that bearing is stuck, and long service life and reliable.The utility model improves and aims to provide a kind of bearing that prevents stuck better effects if prior art.
Summary of the invention
The utility model is for prior art deficiency, provide a kind of ball can bear certain deformation, prevent the bearing that bearing ball is stuck.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of bearing, comprise outer race and bearing inner ring, between described outer race and described bearing inner ring, be provided with ball, described bearing inner ring is radially provided with lubrication channel, described bearing inner ring is axially provided with lubrication hole, described lubrication hole is connected with described lubrication channel, ball inside is provided with cavity, on described ball, being provided with duct is connected cavity with ball outside, in described cavity, be provided with sponge, described sponge absorption has lubricating grease.This bearing in the time being subject to impacting because ball inside is provided with cavity, therefore there is certain deformation leeway, thereby it is stuck that this bearing can be prevented, simultaneously owing to being provided with sponge in bearing, on sponge, absorption has lubricating grease, and in the time that ball is subject to deformation, thereby the deformation of ball extruding sponge is extruded the lubricating grease in sponge in duct, lubricating grease plays the effect that ball is lubricated, thereby makes the anti-jamming better effects if of bearing.
In technique scheme, be provided with the breach along greatest circle girth for bearing ball deformation on described ball, described notch length is greater than the half of described ball greatest circle girth.The deformation quantity that this breach increases ball is set on ball, and there is resilience effect, thereby prevent that bearing is stuck.
The utility model compared with prior art, there is following beneficial effect: this bearing of the utility model in the time being subject to impacting because ball inside is provided with cavity, therefore there is certain deformation leeway, thereby it is stuck that this bearing can be prevented, simultaneously owing to being provided with sponge in bearing, on sponge, absorption has lubricating grease, in the time that ball is subject to deformation, thereby the deformation of ball extruding sponge is extruded the lubricating grease in sponge in duct, lubricating grease plays the effect that ball is lubricated, thereby makes the anti-jamming better effects if of bearing.
Brief description of the drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the structural representation of ball in the utility model.
the concrete structure of implementing
Below in conjunction with accompanying drawing and the concrete structure of implementing, the utility model is described in further detail: referring to Fig. 1 to Fig. 2, a kind of bearing, comprise outer race 1 and bearing inner ring 2, between described outer race 1 and described bearing inner ring 2, be provided with ball 3, described bearing inner ring 2 is radially provided with lubrication channel 21, described bearing inner ring 2 is axially provided with lubrication hole 22, described lubrication hole 22 is connected with described lubrication channel 21, ball 3 inside are provided with cavity 31, on described ball 3, being provided with duct 32 is connected cavity 31 with ball 3 outsides, in described cavity 31, be provided with sponge 33, described sponge 33 absorption have lubricating grease.This bearing in the time being subject to impacting because ball 3 inside are provided with cavity 31, therefore there is certain deformation leeway, thereby it is stuck that this bearing can be prevented, simultaneously owing to being provided with sponge 33 in bearing, on sponge 33, absorption has lubricating grease, and in the time that ball 3 is subject to deformation, thereby the deformation of ball 3 extruding sponge 33 is extruded the lubricating grease in sponge 33 in duct 32, lubricating grease plays the effect that ball 3 is lubricated, thereby makes the anti-jamming better effects if of bearing.
On described ball 3, be provided with the breach 34 along greatest circle girth for bearing ball 3 deformation, described breach 34 length are greater than the half of described ball 3 greatest circle girths.This breach 34 is set on ball 3 and increases the deformation quantity of ball 3, and there is resilience effect, thereby prevent that bearing is stuck.
