Description
Technical field
The utility model relates to technical field of bearings, and in particular to a kind of cylinder roller bearing retainer.
Background technique
Cylinder roller bearing retainer, several pillars including two annular frames of two annular frames and connection, phase
Hole between adjacent pillar is the pocket hole of cylinder roller bearing retainer, and pocket hole plays the role of that roller is isolated, and can limit
Cylinder roller bearing processed is circumferentially mobile, and traditional pocket hole is mostly straight pocket hole, since pocket hole surface is vertical, can not limit roller and radially alter
Dynamic, roller easily falls when causing to assemble, hardly possible is assembled, and retainer radially can be altered significantly in cylinder roller bearing operating
Dynamic, in order to solve the above technical problems, existing pocket hole is mostly cylindrical pocket hole, the side wall in cylindrical pocket hole is equipped with locking point
Angle, for limiting roller radial-play, but the prior art will appear the feelings that locking wedge angle scrapes roller grease in actual use
Condition makes occur oil-poor state inside pocket hole, and so as to cause roller and pocket hole contact site insufficient lubrication, friction Temperature Rise aggravates, most
The bearing operation service life is influenced eventually.
Summary of the invention
A kind of installation more more convenient than the prior art that in order to overcome the deficiencies of the prior art, the utility model provides, can be more
Good guide rolls, prevent bearing from falling apart and lubricate good cylinder roller bearing retainer.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of cylinder roller bearing retainer, packet
It includes two annular frames and connects several pillars of two annular frames, the gap between adjacent struts forms accommodating cylinder rolling
The pocket hole of son, two groups of lockings protrusions are provided on the opposite face of adjacent two pillar, and two groups of locking protrusions are located at phase
The both ends on opposite, one group of locking protrusion include that two locking protrusions of the correspondence two sides of opposite face are arranged in, the locking protrusion
Inclined surface including the locking plane parallel with the opposite face of pillar and with the opposite face of pillar in obtuse angle, adjacent two pillar
Opposite face on corresponding locking plane constitute fore shaft, the distance of the fore shaft two sides is less than the diameter of cylindrical roller, described one
Two inclined surface in group locking protrusion are oppositely arranged.
In above-mentioned technical proposal, when in use, fore shaft, which plays, prevents cylindrical roller from falling, keeps cylindrical roller stable
Effect, while bearing being facilitated to install, two groups of lockings protrusions, the opposite face of inclined surface and pillar is provided on the opposite face of pillar
It is arranged in obtuse angle, and is oppositely arranged with the inclined surface of group locking protrusion, keeps cylindrical roller tangent with inclined surface at runtime, reduce
The contact surface of cylindrical roller and retainer, it is possible to reduce abrasion prolongs the service life, while cylindrical roller and with group inclined surface
Between space can play the role of oil storage, supplemental lubrication, can prevent roller oil film truncation the case where, guarantee cylinder rolling
Oil film on son is uniform, lubricates sufficiently in pocket hole, makes cylindrical roller stable operation in pocket hole.
As the further setting of the utility model, the locking protrusion is that pillar is opposite along the width of annular frame radial direction
The 1/3 of face width.
In above-mentioned technical proposal, locking protrusion along annular frame radial direction width be sidewall width 1/3 when, guarantee pocket
Hole can endurance strength cylindrical roller it is radially movable while, guarantee cylindrical roller lubricated in pocket hole sufficiently, it is stable.
The utility model is further arranged to: the annular frame and pillar are made of PPS plastics.
In above-mentioned technical proposal, PPS plastic holder has high intensity not available for common nylon, wearability, heat-resisting
The advantages that property.PPS plastics have excellent corrosion resistance simultaneously, when especially using cylinder roller bearing within the compressor, due to
Compressor and freeze machine oil contains ammonium hydroxide, and PPS plastic holder can substitute the brass retainer intolerant to ammonium hydroxide corrosion completely.
As the further setting of the utility model, the pillar is equipped with trapezoidal groove.
In above-mentioned technical proposal, trapezoidal groove can improve the processing quality of retainer, prevent pillar due to wall unevenness
And generate and shrink, deformation, and can effectively reduce retainer weight, reducing retainer operates centrifugal force, promotes bearing high speed
Can, while the elasticity of fore shaft can be improved by removing some materials outside pocket hole at aperture, so that roller is packed into retainer pocket hole
It is more easy and convenient.
As the further setting of the utility model, the pillar is the bucking ladder that medial surface is less than lateral surface.
In above-mentioned technical proposal, while reducing retainer weight, cylindrical roller can be made more stable at runtime.
The utility model is further described with reference to the accompanying drawing.
Detailed description of the invention
Attached drawing 1 is the utility model specific embodiment appearance diagram；
Attached drawing 2 is the sectional view of the utility model specific embodiment in actual use；
Attached drawing 3 is the enlarged drawing of the part A of attached drawing 2.
Specific embodiment
Specific embodiment of the utility model is as shown in Figure 1-3, the side towards annular frame axis of the pillar is
Medial surface, the side far from annular frame axis are lateral surface, a kind of cylinder roller bearing retainer, including two annular frames
1 and two annular frames 1 of connection several pillars 2, the gap between adjacent struts 2 forms the pocket hole 3 of accommodating cylindrical roller,
Two groups of locking protrusions 4 are provided on the opposite face of adjacent two pillar 2, two groups of locking protrusions 4 are located at opposite face
Both ends, one group of locking protrusion 4 includes two locking protrusions 4 that the correspondence two sides of opposite face are arranged in, and the locking protrusion 4 includes
The locking plane 41 parallel with the opposite face of pillar 2 and inclined surface 42 with the opposite face of pillar 2 in obtuse angle, described adjacent two
Corresponding locking plane 41 constitutes fore shaft 43 on the opposite face of column 2, and the distance of 43 two sides of fore shaft is less than the straight of cylindrical roller
Diameter, when in use, the effect that fore shaft 43, which plays, to be prevented cylindrical roller from falling, keep cylindrical roller stable, while facilitating axis
Hold installation, two inclined surface 42 in one group of locking protrusion 4 are oppositely arranged, cylindrical roller at runtime with 42 phase of inclined surface
