Description
Technical field：
Technical field of bearings is the utility model is related to, more specifically to a kind of baler special piston roller bearing.
Background technology：
Because the working environment of farm machinery is more severe, so the deep groove ball bearing of farm machinery requires preferably
Sealing property, in addition to waterproof sealing, it is also necessary to prevent dust and foreign matter from entering bearing, cause the sealing property of bearing to become
Difference, so as to influence the service life of bearing.
Utility model content：
The purpose of this utility model and provides a kind of baler special piston roller shaft aiming at the deficiency of prior art
Hold, the two sides of its bearing is provided with dust-proof end cap, and the dust-proof end cap in bottom has waterproof and anti-foreign matter enters the function of bearing, top
The dust-proof end cap in portion has the function that anti-foreign matter enters bearing or foreign object damage bearing.
Technology solution of the present utility model is as follows：
Baler special piston roller bearing, including inner ring, outer ring, retainer and ball, ball are arranged on retainer,
Retainer is clamped between inner ring and outer ring, and oil sealing is provided between inner ring and outer ring；Axle sleeve is consolidated on inner ring and with inner ring
Be scheduled on together, the inner wall lower of outer ring forms annular groove under outer ring, the dust-proof end cap sleeve in bottom of plate-like in annular groove under outer ring,
The dust-proof end cap in bottom is together with annular groove Elastic Contact blocking under outer ring；
The dust-proof end cap sleeve in top is fixed together on axle and with axle, and bulge loop, outer ring are formed on the dust-proof end cap in top
Upper surface shaping outer ring on annular groove, bulge loop is placed on outer ring in annular groove, and the bottom of the dust-proof end cap in top is pressed against the upper of inner ring
On end face.
The oil sealing is formed by being adhesively fixed with rubber lip envelope on oil tight skeleton, oil tight skeleton sleeve ring on the inwall of outer ring
In groove, the lip elasticity of rubber lip envelope is pressed in the outer diameter face of inner ring.
The beneficial effects of the utility model are：
The two sides of its bearing is provided with dust-proof end cap, and there is the dust-proof end cap in bottom waterproof and anti-foreign matter to enter the work(of bearing
Can, the dust-proof end cap in top has the function that anti-foreign matter enters bearing or foreign object damage bearing.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
In figure：1st, inner ring；2nd, outer ring；21st, annular groove under outer ring；22nd, annular groove on outer ring；23rd, annular groove on the inwall of outer ring；3rd, protect
Hold frame；4th, ball；5th, oil sealing；6th, axle；7th, the dust-proof end cap in bottom；8th, the dust-proof end cap in top；81st, bulge loop.
Embodiment：
Embodiment：As shown in Figure 1, baler special piston roller bearing, including inner ring 1, outer ring 2, retainer 3 and ball
4, ball 4 is arranged on retainer 3, and retainer 3 is clamped between inner ring 1 and outer ring 2, and oil is provided between inner ring 1 and outer ring 2
Envelope 5；The sleeve of axle 6 is fixed together on inner ring 1 and with inner ring 1, and the inner wall lower of outer ring 2 forms annular groove 21 under outer ring, disk
The dust-proof sleeve of end cap 7 in bottom of shape is under outer ring in annular groove 21, the dust-proof end cap 7 in bottom and the Elastic Contact blocking of annular groove 21 under outer ring
Together；
The dust-proof sleeve of end cap 8 in top is fixed together on axle 6 and with axle 6, and bulge loop is formed on the dust-proof end cap 8 in top
81, the upper surface of outer ring 2 is molded annular groove 22 on outer ring, and bulge loop 81 is placed on outer ring in annular groove 22, the bottom of the dust-proof end cap 8 in top
It is pressed against on the upper surface of inner ring 1.
The oil sealing 5 is formed by being adhesively fixed with rubber lip envelope 52 on oil tight skeleton 51, and the sleeve of oil tight skeleton 51 is in outer ring
On inwall in annular groove 23, the elasticity of lip 521 of rubber lip envelope 52 is pressed in the outer diameter face of inner ring 1.
Operation principle：The dust-proof sleeve of end cap 7 in bottom of plate-like is under outer ring in annular groove 21, the dust-proof end cap 7 in bottom and outer ring
The lower Elastic Contact blocking of annular groove 21 is together；The dust-proof end cap 7 in bottom can prevent water and foreign matter from entering bearing.
The dust-proof end cap 8 in top has been mainly to prevent foreign matter from encountering oil sealing 5, allows oil sealing 5 to damage, at the same also have prevent foreign matter
Into the function of Bearing inner.
