Abstract
The invention relates to a needle bearing, and in particular relates to a needle bearing for a punching cage, which has feature structure and belongs to the field of a bearing. The needle bearing comprises a bearing outer ring, a needle and a cage, wherein the cage is arranged in the bearing outer ring, a plurality of pockets are formed on the cage, the needle is arranged in a space formed by the pockets and the bearing outer ring; the shape of the cage is changed, the section is changed from primary bow-shape into present U-shape, and furthermore, the welding is not required, therefore, not only is the machining difficulty reduced, the machining process is simplified, and also the strength is increased; by improving the form of the pockets of the punching cage, two lock points have a certain gap in the middle, therefore the lubricating oil can be stored conveniently.
Description
Technical field
The present invention relates to a kind of needle bearing, specifically relate to a kind of punching press frame needle bearing of feature structure, 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 the 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 is difficult, needs the welding equipment of special special use, and cost is high, and precision is difficult for guaranteeing; 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, study a kind of both easily processing, 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 object of the invention is to provide a kind of punching press frame needle bearing of special construction.
For achieving the above object, the technical solution adopted in the present invention is 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, difference oil storage tank A, 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 invention has the advantages that:
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.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention;
Fig. 2 is common punching press frame needle bearing structure diagram;
Fig. 3 is common pressing cage structure sketch;
Fig. 4 is structure diagram of the present invention;
In figure: 1, outer ring, 2, retainer, 3, ball, 4, locking point A, 5, locking point B, 6, oil storage tank A, 7, oil storage tank B, 8, oil storage tank C, the projection at 9,70 ° of angles.
Embodiment
In order further to understand this punching press frame needle bearing, below in conjunction with accompanying drawing, be described as follows.
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, respectively oil storage tank A, oil storage tank B and oil storage tank C; Oil storage tank A with in oil storage tank B, be respectively equipped with a projection that becomes 70 ° of angles.
