Description
Technical field
The present invention relates to retainer technical field, specifically a kind of brass entity aligning roller bearing retainer.
Background technique
The existing brass retainer of selfaligning roller bearing is interference type arrangement, this retainer comprises a central ring, ring both sides are some lintels, it is roller mounting hole between lintel, retainer external diameter is cylindrical, and such as disclosed in Chinese patent CN101586628A, a kind of solid bearing retainer of self-aligning bearing just belongs to this structure.The roller axially locating that this design proposal Problems existing is is imperfect, therefore rigidity shelves limit must be furnished with in inner ring raceway both sides, in actual use, when main shaft occurs inevitably misaligning operating mode, will occur that serious stress is concentrated in the wherein side of roller chamfer, cause the premature failure of a whole set of bearing; When bearing bears larger thrust load, easily cause inner ring rigidity rib oil duct place to split, cause bearing premature deterioration; And this design is by structural limitations such as oil ducts, can not apply reinforced design.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of brass entity aligning roller bearing retainer, improving the overall performance of retainer, and providing the manufacture method of this retainer simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of brass entity aligning roller bearing retainer, comprise retainer body, retainer body is integrated by machining, it is characterized in that, there is in described retainer body the equally distributed roller mounting hole of two row, two row mounting holes are dislocatedly distributed, the adduction prostomum cylinder that described retainer body comprises central ring and extends to bilateral symmetry from central ring, at the uniform some roller mounting holes of machining of described adduction prostomum cylinder circumference, and the axis normal of described roller mounting hole intersects at a point, roller is arranged in roller mounting hole and can leans on roller self-priming retainer.
The inner and outer surface of described adduction prostomum cylinder is parallel to each other, and parallel with roller rotational axis.
Described roller mounting hole bi-side are the curved surface pocket hole with rollers co-operate, and both ends of the surface are plane, and are provided with the technique chamfering of installing roller in the outside of roller mounting hole, load roller mounting hole outside roller self-sustaining frame.
Four corners of described roller mounting hole are provided with stress relief breach, avoid stress to concentrate.
Curvature of curved surface and the roller rolls face curvature of described roller mounting hole match.
The inner and outer surface of described central ring is the ring surface concentric with bearing inner race, facilitates machining.
Roller mounting hole on described retainer body is formed by removing material technology by machining on brass blank.
A kind of brass entity aligning roller bearing retainer forming method,
First prepare a brass blank, then first time machining is carried out to its inner and outer surface and form the thin central ring in thick both sides, a centre and adduction prostomum cylinder;
Then on brass blank, form two row roller mounting holes by NC Milling Technology, roller mounting hole is evenly distributed on retainer body circumference;
In each roller mounting hole and retainer external diameter intersection place's machining assembly technology chamfering, roller can be encased in mounting hole outside retainer.
While numerical control milling roller mounting hole, also in the lump at roller mounting hole four corner's machining stress release breach, stress is avoided to concentrate.
The invention has the beneficial effects as follows:
1, high-mechanic load, retainer integrated machine is processed to form, and balance is better, and intensity is high, and inner ring is without the need to doing rigidity rib, and the roller quantity that can hold and roller dimension are more larger, can carry higher load;
2, low noise, low vibration, the side of Integral retainer is curved surface, and the outer surface of curved surface and roller matches, and can form better matching relationship, forms oil film, both guide rolls can rotate, and also can reduce the stirring resistance of lubricant oil, and reduced noise;
3, Integral retainer, discharges breach by design stress simultaneously, and release concentrated stress, can well improve stability, prevent the distortion produced in using process;
4, brass material, has self-lubricating property, 2 low wearing and tearing, longer service life.
5, can select roller guide mode according to applying working condition, retainer of the present invention can be combined into outer ring guidance mode with outer guided rings, or is combined into inner ring guidance mode with interior guided rings, when without being roller guide mode during guided rings.Adopt during roller guide mode and can save guided rings cost.
Accompanying drawing explanation
Fig. 1 is stereogram of the present invention;
Fig. 2 is plan view;
Fig. 3 is A-A sectional view in Fig. 2.
In figure: 1 retainer body, 11 central rings, 12 adduction prostomum cylinders, 2 roller mounting holes, 21 curved surface pocket holes, 22 planes, 3 technique chamferings.
Embodiment
As shown in Figure 1 to Figure 3,
A kind of brass entity aligning roller bearing retainer, comprise retainer body 1, retainer body is integrated by machining, first a brass blank is prepared, then first time machining is carried out to its inner and outer surface and form the thin central ring 11 in thick both sides, a centre and adduction prostomum cylinder 12, the inner and outer surface of central ring is the ring surface concentric with bearing inner race, facilitates machining.The inner and outer surface of adduction prostomum cylinder is parallel to each other, and parallel with roller rotational axis.Then on brass blank, two row roller mounting holes 2 are formed by NC Milling Technology, roller mounting hole 2 is evenly distributed on retainer body circumference and the axis normal of all rollers mounting hole intersects at a point, and roller is arranged in roller mounting hole and can leans on roller self-priming retainer; Wherein, two row roller mounting holes are dislocatedly distributed.
Roller mounting hole 2 bi-side are the curved surface pocket hole 21 with rollers co-operate, both sides curvature of curved surface and the roller rolls face curvature of roller mounting hole match, both ends of the surface are plane 22, in each roller mounting hole and retainer external diameter intersection place's machining assembly technology chamfering 3, roller can be encased in mounting hole outside retainer.And four of roller mounting hole corners are provided with stress relief breach (not shown in FIG.), stress is avoided to concentrate.
Embodiment recited above is described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in protection domain as determined in claims of the present invention.
