Abstract
The utility model relates to a belong to angular contact bearing technical field, concretely relates to long service life, the production process is to low in the pollution of the environment, low cost's angular contact bearing punching press holder, it includes toper holder body, its characterized in that: the pocket hole of evenly distributed's guide rolling element on the holder body circumferencial direction, all be provided with the boss to pocket hole center directions on the inner wall arc surface in pocket hole. The towing and force -bearing cable is advantageous in that, the utility model discloses a high -quality panel to through the smelting production processes who has optimized, the life that the product structure of optimization, the product that produces have not only increased the bearing has still reduced the manufacturing cost of bearing.
Description
Technical field
The utility model relates to and belongs to angular contact bearing technical field, is specifically related to a kind of long service life, angle contacting angular contact bearing pressing cage with low cost.
Background technique
As everyone knows, retainer is one of vitals of rolling bearing, and its effect is in bearing working, guide rolling element to run well, and at any time keeps rolling element not depart from bearing.In addition, in order to obtain good operating condition or installation conditions, retainer generally also need control the free movement of the relative retainer of rolling element, can not limit narrow to rolling element so that can not freely rotate, and can not cross pine so that assembling or installation difficult.Usually, retainer keeps rolling element not depart from by constraint rolling element outer surface, described outer surface is ball surface to ball bearing speech, roller bearing is sayed it is outer round surface, all load-bearing surface or the working surface of rolling element in a word, inevitably working surface being had an impact when there is effect of contraction like this, as the oiling agent flow direction, wearing and tearing difference etc., thus affecting the performance and used life of bearing.
In the prior art of angular contact bearing wherein, due to unstability and the production technology of its structure, cause production process befouling environment, while not only increase cost and additionally reduce working life; Its retainer material is generally copper and nodular cast iron, and the retainer that this material is made often has the situation wearing away powder to occur in rotary course, and its Principle of Rotating is with the contact of roller branch line face, also likely directly lubricant oil is rotated and scrape in process; But bearing can High Rotation Speed with vibrations in installation using process, if having lubricant oil to reduce and wear away the interference of powder, this not only increases the wearing and tearing of bearing, also greatly reduces the working life of bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of long service life, angular contact bearing pressing cage with low cost.
The technical solution of the utility model is: a kind of angular contact bearing pressing cage, it comprises taper retainer body, it is characterized in that: described retainer and the pocket hole at described retainer body circumferentially equally distributed guiding rolling element, the inwall arc surface in described pocket hole is provided with the boss to pocket hole central direction.Described boss quantity is 4.Described taper retainer body is 08AL sheet material material.
The utility model advantage is, long service life, and production process environmental pollution is few, with low cost.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is that state of the present utility model carries out structural representation.
In figure, 1 is retainer body, and 2 is pocket hole, and 3 is boss, and 4 is rolling element.
Embodiment
The utility model is a kind of angular contact bearing pressing cage, it comprises taper retainer body (1), it is characterized in that: the pocket hole (2) of described retainer body (1) circumferentially equally distributed guiding rolling element (4), the inwall arc surface of described pocket hole (2) is provided with the boss (3) to pocket hole (2) central direction.Described boss (3) quantity is 4.Described taper retainer body (1) is 08AL sheet material material.Described in described accompanying drawing 1, pocket hole (2) quantity is 20, and retainer (1) thickness is 3.0mm.
Wherein, production process of the present utility model is: 1, blanking, and cutting with guillotine shear needs plate, and detect thickness of slab 3.0mm, error is no more than 0.1mm; Whether inspection plate face is smooth, rusty stain, scratches; And board selection 08AL sheet material;
2, enclosure, welding, with plate bending rolls by material enclosure, with butt welding machine welding, and detect soldered and whether have pore, sand holes, dry joint connects;
3, shaping, shaping with 315 tons of oil hydraulic presses, and detect wall thickness 3.0mm, error is no more than 0.05mm;
4, car endoporus, uses C260 numerical tool operation, and concentricity is 0.05mm;
5, recessing, with numerical tool operation, concentricity is 0.05mm;
6, pressure hole, utilizes 80 tons of punch presses, and detecting high variation at the bottom of fenestra is Vhc0.22, and deck-siding variation is Vbc0.35, and uses special pressure Kong Ren;
Flexibly whether 7, pressure slope, utilizes 80 tons of punch presses, detect and to rotate, whether have stuck phenomenon;
8, repair burr, polishing, utilize buffing machine polishing, detect feel ko-hemp cloth impulse-free robustness and acute angle, range estimation surface is without scuffing, iron mold.
In enforcement, the utility model board selection 08AL sheet material, this material impact-resistant function is good, and do not have and wear away powder phenomenon, retainer is arranged 4 boss, boss, with roller four point cantact by revolution space, can allow lubricant oil own lubrication in space, which increases bearing working life.While changes in material, also production process is optimized, compared with prior art, the utility model does not need also to need to pass through smelting process as copper and nodular cast iron, the utility model directly adopts high-quality sheet material, shear in die mould welding, greatly reduce so again the pollution of smelting process to environment, saved the energy; The more important thing is, cost of the present utility model only has 60% of copper cage, is 90% of nodular cast iron retainer; In addition the utility model also can be made into double row angular contact bearing stamping retainer.As can be seen here, the advantage of the utility model product is mainly, the working life not only adding bearing also reduces the cost of production of bearing, and this product is suitable for large-scale industrial production.
