Abstract
The invention relates to a novel high strength and high stability stamping retainer of a cylinder roller bearing. The retainer uses the steel plates with thickness being not more than 2mm as the materials, thus fully reducing the dead weight of the bearing and improving the rotating speed of the bearing. The pockets and the appearance of the retainer are stamped once and finally undergo secondary reshaping and phosphating. The pockets of the retainer are square, thus reducing the machining difficulty and fully meeting the requirement of mass production. The width of the pockets of the retainer is 0.985 times the diameter of the roller in design and the length thereof is 1.02 times that of the roller in design, thus ensuring the external diameter of the roller set not to interfere with the outer ring flange, ensuring final smooth assembly of the bearing, tightly pressing sag of the retainer and effectively improving the stability of operation.
Description
Technical field
The present invention relates to a kind of novel high-strength, high stability stamping retainer of cylinder roller bearing.
Background technique
Roller bearing belongs to and can bear big radial load and can bear the bearing of certain micro-thrust load again, has advantages of high bearing capacity, also is applicable to high rotational speed.Be widely used in the middle of all kinds of mechanical parts, act on of crucial importancely, retainer adopts brass and nylon material more.But for the higher roller bearing of big, working speed in batches, shock resistance, stability requirement, traditional copper and nylon cages can't satisfy the usage requirement of equipment.Though the copper holder impact strength is better, the processing technology complexity is unfavorable for that production in enormous quantities processing and cost are higher; Though and the nylon cages working speed higher, be easy to produce in batches because self material is more crisp, impact strength a little less than.Therefore, press in the present mechanical industry to develop and a kind ofly can satisfy production in enormous quantities, can satisfy high workload rotating speed, high strength again, the cylinder roller bearing retainer of high stability.
Summary of the invention
The objective of the invention is: propose a kind ofly can satisfy production in enormous quantities, can satisfy high workload rotating speed, high strength again, the cylinder roller bearing retainer of high stability.
Technological scheme of the present invention is: novel high-strength, high stability stamping retainer of cylinder roller bearing are material with the steel plate of thickness≤2mm, have fully reduced the bearing deadweight, improve the rotating speed of bearing; Punch process of this retainer pocket hole and profile is finished, and carries out secondary reshaping and phosphatization at last again; The square hole form is adopted in this retainer pocket hole, has reduced difficulty of processing, fully satisfies requirement of mass production; This retainer pocket hole width is designed to 0.985 times of roller diameter, Design of length is 1.02 times of roller length, can guarantee that roller set outside diameter do not interfere with the outer ring rib, guarantees the final assembling smoothly of bearing, press tight retainer sag of chain, improved the stability of running effectively.
This retainer is based on guiding, compact structure, Spielpassung is proper, and the high hardness of self material can be born higher impulsive load in addition, in addition, because steel plate toughness is better, the retainer deck-siding can be slightly narrower than copper holder, so just means the increase along with diameter series, design the rolling element that issue face can consider to increase some at bearing main body, bearing capacity has also obtained significantly improving.
The invention has the beneficial effects as follows: well satisfied the usage requirement of the higher roller bearing of big in batches, working speed, mechanical strength, stability requirement, on the basis of improving bearing load carrying capacity, cutting down finished cost, its stability, shock resistance and working speed have significantly been improved, through overtesting, this novel retainer increases by 15% on year-on-year basis than conventional construction retainer bearing capacity; Rotating speed can improve 20%, and cost reduces by 10%.Satisfy user's usage requirement comprehensively.For certain effect of actively promoting has been played in China's bearing foreign exchange earning.
Description of drawings:
Fig. 1 is the structural representation of roller bearing.
Among the figure: 1. outer ring, 2. check ring, 3. cylindrical roller, 4. retainer, 5. inner ring.
Fig. 2 is structural representation of the present invention and A-A sectional drawing thereof.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, novel high-strength, high stability stamping retainer of cylinder roller bearing are that the steel plate of 1.5mm is a material with thickness, and punch process of pocket hole and profile is finished, and carries out secondary reshaping and phosphatization at last again; The square hole form is adopted in this retainer pocket hole, and its width is designed to 0.985 times of roller diameter, and Design of length is 1.02 times of roller length.
The retainer of above-mentioned preparation is applied on as shown in Figure 1 the roller bearing, and roller bearing comprises outer ring 1, check ring 2, cylindrical roller 3, retainer 4 and inner ring 5.Cylindrical roller 3 is distributed on the raceway that outer ring 1 and inner ring 5 form and by the some pockets hole on the retainer 4 evenly to be separated; Check ring 2 contacts with groove interference on 1 internal diameter direction of outer ring by the elasticity of himself, thereby does not separate with other parts assurance outer ring 1.
