Abstract
The present invention relates to a kind of anti abrasive unilateral bearings.The device includes drawn cup, the end face of drawn cup offers end cap slot, unidirectional multiple reducing slots are uniformly provided on the inside of drawn cup, retainer is installed on the inside of drawn cup, roller holes and positive stop lug boss are provided on the position of retainer corresponding with reducing slot, roller is installed in reducing slot, roller exposes retainer, spring leaf is connected on positive stop lug boss, spring leaf is located in reducing slot and end contradicts and more are provided on roller, on the inside of drawn cup for placing the annular oil guide groove of lubricant.Since oil guide groove exists in the device, when roller rotates, the lubricant in oil guide groove can be applied to roller surface, so as to mitigate the abrasion between roller and axis, and oil guide groove can guide lubricant to flow to, and make each roller that can apply and spread lubricant, ensure that the unilateral bearing effectively works.The device can be used as anti abrasive unilateral bearing, safe and reliable.
Description
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of unilateral bearing.
Background technology
A kind of unilateral bearing is disclosed in existing Chinese patent database, number of patent application is：
201220509364.9 the applying date is：2012.09.26, notification number is：203114902 U of CN, the day for announcing be：
2013.08.07 structure includes：Outer ring, roller and retainer, the roller are mounted in the roller holes on retainer, and
Expose retainer, retainer is mounted in outer ring, it is characterised in that：It is uniformly provided on the inside of the outer ring unidirectional more
A limiting slot, the outside of retainer also uniformly have the protrusion being adapted to limiting slot of identical quantity；Also have on the retainer
There is reed frame, reed is inserted on reed frame, and the elastic force end of reed offsets with roller.It is disadvantageous in that：Due to the dress
Put no inner ring, be that roller is directly in contact with axis, it is larger to the abrasion of axis, so lubrication quality directly determine it is anti abrasive
The working performance of unilateral bearing, and the equipment is not defined and describes to the correlation circumstance of lubrication.
The content of the invention
The purpose of the present invention is stablizing in view of the deficienciess of the prior art, providing a kind of greasy property, structure is more stepped up
Gather together reason, the anti abrasive unilateral bearing of service life length.
In order to realize the purpose of foregoing invention, the technical solution used in the present invention：
A kind of anti abrasive unilateral bearing, includes drawn cup, and the end face of drawn cup offers to fix the end of end cap
Cover slot is uniformly provided with unidirectional multiple reducing slots on the inside of drawn cup, retainer is installed on the inside of drawn cup,
Roller holes and positive stop lug boss are provided on the position of retainer corresponding with reducing slot, roller is installed in the reducing slot, are rolled
Son exposes retainer, and spring leaf is connected on the positive stop lug boss, and spring leaf is located in reducing slot and end is contradicted on roller,
More are provided on the inside of the drawn cup for placing the annular oil guide groove of lubricant.
During present invention work, unilateral bearing is sleeved on axis, the roller on unilateral bearing is made to contradict on axis.With it is existing
Technology is compared, and beneficial effects of the present invention are：Due to there is the oil guide groove for placing lubricant in the device, when roller rotates
When, the lubricant in oil guide groove is applied to roller surface, and so as to mitigate the abrasion between roller and axis, and oil guide groove can guide profit
The flow direction of lubrication prescription makes each roller that can apply and spreads lubricant, ensures that the anti abrasive unilateral bearing effectively works.The device
It can be used as anti abrasive unilateral bearing, it is safe and reliable.
For the ease of lubricant reservoir in oil guide groove, the lubricant selects lubricating grease.
Further, the end cap is welded in the end cap slot of drawn cup.
Further, the screw thread being screwed on for end cap is equipped in the end cap slot.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the structure diagram of drawn cup in Fig. 1.
Fig. 3 for Fig. 2 along the sectional view of A-A.
Wherein, 1 drawn cup, 101 reducing slots, 102 end cap slots, 103 oil guide grooves, 2 rollers, 3 retainers, 301 roller holes,
302 positive stop lug boss, 303 spring leafs, 4 end caps.
Specific embodiment
As shown in Figs. 1-3, it is a kind of anti abrasive unilateral bearing, includes drawn cup 1, the end face of drawn cup 1 is opened
Equipped with for fixing the end cap slot 102 of end cap 4, the inside of drawn cup 1 is uniformly provided with unidirectional multiple reducing slots
101, the inside of drawn cup 1 is installed with retainer 3, and roller holes are provided with on the position of 101 corresponding retainer 3 of reducing slot
301 and positive stop lug boss 302, roller 2 is installed in reducing slot 101, roller 2 exposes retainer 3, is connected on positive stop lug boss 302
Spring leaf 303, spring leaf 303 is located in reducing slot 101 and end is contradicted on roller 2, and the inside of drawn cup 1 is provided with more
Root is used to place the annular oil guide groove 103 of lubricant, for the ease of lubricant reservoir in oil guide groove 103, lubricant selection profit
Consistent lubricant, further, end cap 4 are welded in the end cap slot 102 of drawn cup 1.
During work, anti abrasive unilateral bearing is sleeved on axis, contradicts the roller 2 on anti abrasive unilateral bearing
On axis.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
Art personnel are not required performing creative labour that can make one to some of which technical characteristic according to disclosed technology contents
A little to replace and deform, these are replaced and deformation is within the scope of the present invention.
