Abstract
The utility model relates to a needle bearing, in particular relates to a pressed cage needle bearing with a feature structure and belongs to the field of bearings. The bearing comprises a bearing outer ring, a rolling needle and a cage, wherein the cage is arranged in the bearing outer ring; a plurality of pockets are arranged in the cage; the rolling needle is arranged in a space formed by the pockets and the bearing outer ring to change the shape of the cage. The bearing has the advantages that an original bow-shaped section is changed into a U-shaped section at present and welding is not needed, so that the processing difficulty is reduced, the processing process is simplified and the strength is increased; the pressed cage pocket form is changed, the number of the locking points is changed into two and a certain gap is reserved between the two points, so that lubricating oil is conveniently stored.
Description
Technical field
The utility model relates to a kind of needle bearing, specifically relates to a kind of punching press frame needle bearing of feature structure, and it belongs to field of bearings.
Background technique
Since two thousand six, China's oil mechanical increase in the urban population is very fast, the demand of petroleum machinery bearing has also been strengthened, and demand in the following several years still keeps increment situation.Therefore,, in order to adapt to the requirement of its high-mechanic, high reliability, supporting with it oil recovery machiner is seemed to more and more important by the demand of bearing.
At present, punching press frame needle bearing for domestic oil recovery machiner, mostly is Plate Welding, and not only processing technology difficulty needs special special welding equipment, and cost is high, and precision is difficult for ensureing; Although only a few is also integrated punching press frame, no matter from design, or from technological angle, not very complete, with the external gap of a big chunk in addition.Therefore, research one is easily processing both, and cost is not high, and the not bad oil recovery machiner of using effect uses bearing imperative.
Summary of the invention
In view of the defect that prior art exists, the purpose of this utility model is the punching press frame needle bearing that a kind of special construction will be provided.
For achieving the above object, the technological scheme that the utility model adopts is a kind of punching press frame needle bearing, it comprises: comprise bearing outer ring, needle roller and retainer, retainer is located in bearing outer ring, and retainer is provided with several pockets hole, in the space that pocket hole and bearing outer ring form, needle roller is installed, it is characterized in that: described retainer adopts " U " font cross section structure, retainer pocket hole internal diameter is provided with two trapezoidal protruding locking points, be respectively locking point A and locking point B, between locking point A and locking point B, leave space, locking point A, locking point B and retainer external diameter form three oil storage tanks, oil storage tank A respectively, oil storage tank B and oil storage tank C, in oil storage tank A and oil storage tank B, be respectively equipped with leg-of-mutton projection.
Described locking point A and locking point B line centered by retainer center.
Described two leg-of-mutton projections line centered by retainer center.
The angle of described two triangular hill ends is 70 °.
The utility model has the advantage of:
1. change retainer shape, become present " U " font cross section, and do not need to weld from original " bow " font cross section, not only reduced the difficulty of processing, simplified processing process, has also increased intensity than in the past.
2. the pressure rack that liquidates pocket well format is improved, and lock point is become to two places, and certain gap is left in centre, the convenient lubricant oil that stores.
3. in the other projection that has respectively 70 ° of angles of an one-tenth of 2 lock points, improved the stress of ascending joint, pocket hole and concentrated, and in loading zone, two projections can also play the effect of guiding needle roller.
