Abstract
The utility model relates to a kind of novel cylindrical roller bearing integral retainer.Comprise retainer body, this retainer body has pocket hole (1), is characterized in: at least one end face of described pocket hole (1), be provided with boss (2), thus it is spacing to carry out radial direction to roller.The utility model is the problem of structure and processing technology existing for existing retainer, the structure of former retainer is improved, the retainer of new structure, structurally change, when removing rivet hole design, retainer pocket hole carries and leaves hold depth, form outer assembly, relying on retainer to carry hold depth, to carry out radial direction to rolling element spacing, and the gyration center of control rolling element, when retainer removes rivet hole, the depression of roller need not be processed, reduce roller manufacturing procedure, rivet also need not be processed, thus greatly reduces the processing cost of a whole set of bearing.During without rivet hole, retainer manufacturing procedure can be reduced, reduce carrying, avoid potential quality problems.
Description
Technical field
The utility model relates to a kind of novel cylindrical roller bearing integral retainer.
Background technique
Be illustrated in figure 1 the integral cage of roller bearing, kind of bearings is mainly used in oil field of metallurgy, such as be arranged on oil sludge stock pump, complete machine is operation in the wild, medium speed, heavy duty, continuous operation, operating temperature is generally between 40 DEG C ~ 80 DEG C, and integral cage operationally thermal expansion coefficient is consistent, and expanded by heating change in retainer each position is consistent, reliable in mechanical performance, stable work in work.
This type of retainer operation in course of working is loaded down with trivial details, labor intensity is large, every procedure all relies on lathe hand-manipulated, and its manufacturing procedure is: cast blank → rough turn internal-and external diameter → thin car internal-and external diameter, chamfering → thin car cuts off → thin car truncation from face, chamfering → line → thick bores pocket hole → rough mill pocket hole → finish-milling pocket hole → slotting pocket hole circle angle → milling oil groove → brill rivet hole → brill rivet counterbore → deburr → sandblasting → oiling, packaging → warehouse-in.Such as to bore rivet hole operation: retainer is through with after last time multistage manufacturing processes, also full circle is carried out, but also there is distortion, former pocket hole dimension perpendicularity also changes, also must go up milling machine finish-milling pocket hole again, after artificial full circle, reprocessing rivet hole size conforms technological requirement, after placing a period of time, pass through because of power timeliness, retainer recovers again the geometrical shape before shaping, geometrical shape changes makes the center-diameter size of rivet hole along with there occurs change, when assembling bearing, rivet and roller shrinkage pool come in contact, in use, roller can cut off rivet and cause bearing failure.
Model utility content
The purpose of this utility model is to provide a kind of novel cylindrical roller bearing integral retainer, retainer can be relied on to carry hold depth carry out rolling element radial spacing reliably while removing rivet hole.
A kind of novel cylindrical roller bearing integral retainer, comprise retainer body, this retainer body has pocket hole, and its specialization is: at least one end face in described pocket hole, be provided with boss, thus it is spacing to carry out radial direction to roller.
Two end faces wherein contacted with roller periphery on described pocket hole are provided with a boss separately.
Wherein boss is located on the end face of close inner ring on described pocket hole.
Transitional surface wherein between boss and pocket hole inwall is inclined-plane or curved surface.
Transitional surface wherein between boss and pocket hole inwall is inclined-plane, and the angle between this inclined-plane and pocket hole inwall is 45 °.
The utility model is the problem of structure and processing technology existing for existing retainer, the structure of former retainer is improved, the retainer of new structure, structurally change, when removing rivet hole design, retainer pocket hole carries and leaves hold depth, form outer assembly, relying on retainer to carry hold depth, to carry out radial direction to rolling element spacing, and the gyration center of control rolling element, when retainer removes rivet hole, the depression of roller need not be processed, reduce roller manufacturing procedure, rivet also need not be processed, thus greatly reduces the processing cost of a whole set of bearing.During without rivet hole, retainer manufacturing procedure can be reduced, reduce carrying, avoid potential quality problems.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model background technique;
Accompanying drawing 2 is structural representation of the present utility model;
Accompanying drawing 3 is the A-A sectional view of Fig. 2;
Accompanying drawing 4 is the B-B sectional view of Fig. 3.
Embodiment
As shown in Figure 2,3, 4, the utility model provides a kind of novel cylindrical roller bearing integral retainer, comprise retainer body, this retainer body having some is rectangular-shaped pocket hole 1 substantially, at least one (interior) end face in described pocket hole 1 is provided with a boss 2, thus it is spacing to carry out radial direction to roller.
Two end faces specifically wherein contacted with roller periphery on described pocket hole 1 are provided with a boss 2 separately, and boss 2 is located on the end face of close inner ring on described pocket hole 1.Transitional surface in addition between boss 2 and pocket hole 1 inwall is inclined-plane or curved surface, angle when transitional surface between boss 2 and pocket hole 1 inwall is inclined-plane between this inclined-plane and pocket hole 1 inwall is 45 °, retainer can be made like this to have slight deformation, and rolling element can move on to the revolution that gyration center position does not affect bearing automatically.Fillet is made at position, retainer pocket hole 1 into, can to eliminate when being right angle because of the potential unfavorable factor that power is concentrated, make the geometric accuracy of retainer more stable.
Retainer of the present utility model can be processed on numerical control machining center, and numerical control machining center is equipped with auxiliary clamp, and numerical control machining center processes product equal portions and is evenly distributed, processing technology dimensional accuracy is high, deformation of products amount is small, can guarantee the geometric accuracy size of product, removes rivet hole man-hour adding, retainer is made to carry hold depth, Cutter Body Processing with Machining Center goes out product, and hold depth process is stablized, and is convenient to assembling, retainer guides more smooth and easy, turns round more flexible.Enter limiting locking to roller, roller is radial free floating in the pocket hole 1 of retainer, to the more radial direction of the roller amount of moving freely.
The utility model is the problem of structure and processing technology existing for existing retainer, the structure of former retainer is improved, the retainer of new structure, structurally change, when removing rivet hole design, retainer pocket hole 1 carries and leaves hold depth, form outer assembly, relying on retainer to carry hold depth, to carry out radial direction to rolling element spacing, and the gyration center of control rolling element, when retainer removes rivet hole, the depression of roller need not be processed, reduce roller manufacturing procedure, rivet also need not be processed, thus greatly reduces the processing cost of a whole set of bearing.During without rivet hole, retainer manufacturing procedure can be reduced, reduce carrying, avoid potential quality problems.
