Abstract
The utility model discloses a bearing for a swing saw motor. The bearing comprises a bearing outer ring and a bearing inner ring, wherein balls are arranged between the bearing outer ring and the bearing inner ring; the bearing inner ring is radially provided with a lubricating channel and is axially provided with lubrication holes, the lubrication holes are connected with the lubricating channel, a magnet ring is arranged on the bearing inner ring, and the magnet ring attracts the balls to be attached to the bearing inner ring. The bearing disclosed by the utility model has the advantages that the magnet ring arranged on the bearing inner ring enables the balls to be still clung to the bearing inner ring after the balls as well as the bearing outer ring and the bearing inner ring are abraded, and locking of the bearing caused when the balls shift between the bearing outer ring and the bearing inner ring is avoided.
Description
Technical field
The utility model relates to machinery manufacturing technology field, specifically a kind of reciprocating saw bearing for electric machine.
Background technique
Development along with modern technologies, most bearing all comprises the ball between bearing inner ring and outer shroud, in the using process of reciprocating saw, because the impact between cutting blade and cut substrate is larger, therefore the vibration of reciprocating saw motor is very large, so the vibration abrasion of reciprocating saw motor bearings is also very fast.Initial ball gapless between inner ring and outer shroud coordinates, when so now ball slides, can not there is stuck situation, and after bearing and ball have certain wearing and tearing, ball, between the outer shroud of bearing and inner ring, play occurs, thereby cause the bearing may be stuck.
Summary of the invention
The utility model is not enough for prior art, 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 reciprocating saw bearing for electric machine, 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, and described bearing inner ring is axially provided with lubrication hole, and described lubrication hole is connected with described lubrication channel, described bearing inner ring is provided with magnet ring, and described magnet ring attracts described ball and the laminating of described bearing inner ring.At bearing inner ring, magnet ring is set ball after ball and outer race and bearing inner ring wearing and tearing is still close on bearing inner ring, prevent that ball play between bearing inner ring and outer race from causing bearing stuck.
In technique scheme, described ball inside is provided with cavity, is provided with duct cavity is connected with ball outside on described ball, in described cavity, is provided with sponge, and described sponge absorption has lubricating grease.This bearing when 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 when 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 for bearing the breach along greatest circle girth of ball deformation on described ball, described notch length is greater than 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 when 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, when 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.
Accompanying drawing explanation
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 reciprocating saw bearing for electric machine, 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, described bearing inner ring 2 is provided with magnet ring 23, and described magnet ring 23 attracts described ball 3 and described bearing inner ring 2 laminatings.At bearing inner ring 2, magnet ring 23 is set ball 3 after ball 3 and outer race 1 and bearing inner ring 2 wearing and tearing is still close on bearing inner ring 2, prevent that ball 3 play between bearing inner ring 2 and outer race 1 from causing bearing stuck.
Described ball 3 inside are provided with cavity 31, be provided with duct 32 cavity 31 is connected with ball 3 outsides on described ball 3, in described cavity 31, are provided with sponge 33, and described sponge 33 absorption have lubricating grease.This bearing when 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 when 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 for bearing the breach 34 along greatest circle girth of ball 3 deformation, described breach 34 length are greater than 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.
