Abstract
The utility model discloses a kind of durable bearing, comprise bearing outer ring, bearing inner race, retainer and roller bearing, described retainer comprises two annular rings, some roller bearings are evenly provided with between two annular rings, be provided with some rotatingshafts between two annular rings, each described roller bearing is at least fitted with three described rotatingshafts.Adopt this structure that rotatingshaft and roller bearing are fitted to make rotatingshaft when roller bearing rotates on retainer can with roller bearing rolling friction, thus reduce the heating value of friction, extend the working life of bearing.
Description
Technical field
The utility model belongs to technical field of bearings, specifically a kind of durable bearing.
Background technique
Existing bearing generally comprises bearing inner race, bearing outer ring, roller bearing or roller bearing and retainer, bearing heating and wearing and tearing are caused due to sliding friction, special under high temperature operation condition, the effect of inertial centrifugal force exacerbates friction, wearing and tearing and heating, retainer can be caused to burn or fracture, cause bearing cisco unity malfunction time serious.Therefore, require that the material of retainer is except having some strength, also must thermal conductivity good, friction factor is little, wear resistance good, impact toughness is strong, density is less and linear expansion coefficient and rolling element are close.In addition, pressing cage need stand more complicated Pressing Deformation, also requires that material has good processibility.What have on the retainer that ask for something is high also can cross one deck silver.Existing pivot friction coefficient is higher, and easily produce a large amount of heats, cause bearing life not long, serviceability is poor.
Summary of the invention
The utility model is not enough for prior art, and provide a kind of durable bearing, this bearing can reduce the friction factor between roller bearing and retainer, reduces the heating value between roller bearing and retainer thus extends working life of bearing.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of durable bearing, comprise bearing outer ring, bearing inner race, retainer and roller bearing, described retainer comprises two annular rings, some roller bearings are evenly provided with between two annular rings, be provided with some rotatingshafts between two annular rings, each described roller bearing is at least fitted with three described rotatingshafts.Adopt this structure that rotatingshaft and roller bearing are fitted to make rotatingshaft when roller bearing rotates on retainer can with roller bearing rolling friction, thus reduce the heating value of friction, extend the working life of bearing.
In technique scheme, preferably, annular ring is provided with some through holes, described rotatingshaft comprises fixing rod and is set in the rotating sleeve on described fixing rod, described fixing rod two ends are provided with the threaded stem that diameter is less than described fixing rod, and described fixing rod two ends lean annular ring and described threaded stem screws fixing through after described through hole with nut.Owing to retainer being provided with a lot of through hole, therefore the fixed position of rotatingshaft can be selected, thus can carry out adaptation to the roller bearing varied in size, and adopts this structure conveniently to disassemble simultaneously.
The utility model compared with prior art, there is following beneficial effect: adopt this structure that rotatingshaft and roller bearing are fitted to make rotatingshaft when roller bearing rotates on retainer can with roller bearing rolling friction, thus reduce the heating value of friction, extend the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of retainer.
Fig. 3 is the sectional view of rotatingshaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 1 to Fig. 3, a kind of durable bearing, comprise bearing outer ring 1, bearing inner race 2, retainer 3 and roller bearing 4, described retainer 3 comprises two annular rings 31, some described roller bearings 4 are evenly provided with between two annular rings 31, be provided with some rotatingshafts 32 between two annular rings 31, each described roller bearing 4 and four described rotatingshafts 32 are fitted.Adopt this structure that rotatingshaft and roller bearing are fitted to make rotatingshaft when roller bearing rotates on retainer can with roller bearing rolling friction, thus reduce the heating value of friction, extend the working life of bearing.
Annular ring 31 is provided with some through holes 33, described rotatingshaft 32 comprises fixing rod 321 and is set in the rotating sleeve 322 on described fixing rod 321, described fixing rod 321 two ends are provided with the threaded stem 323 that diameter is less than described fixing rod 321, described fixing rod 321 two ends lean annular ring 31 and described threaded stem 323 through after described through hole 33 and nut 5 screw fixing.Owing to retainer being provided with a lot of through hole, therefore the fixed position of rotatingshaft can be selected, thus can carry out adaptation to the roller bearing varied in size, and adopts this structure conveniently to disassemble simultaneously.
