Abstract
The utility model discloses a full needle drawn cup needle roller bearing with a retainer. The full needle drawn cup needle roller bearing comprises a bearing outer ring, needle rollers and a retainer, wherein the needle rollers are uniformly distributed in a roller path of a bearing outer ring to form a full needle structure; the retainer is arranged in the bearing outer ring; inner needle locking holes with the same number as that of the needle rollers are formed in the retainer; a needle roller is arranged in each inner needle locking hole, so that the needle roller is fixed; flanges are respectively formed in two sides of the retainer. A transverse beam of the retainer adopts a structure lower than the central diameter of the needle roller. A retainer which does not exist in a general full needle bearing is arranged in the full needle drawn cup needle roller bearing with the retainer; the inner needle locking holes are formed in the retainer, the needle rollers are fixed through an inner needle locking mode, high bearing capacity of the full needle bearing is kept, the problem that the needle rollers drop in the full needle bearing is solved, and the mounting reliability of the bearing is improved. Meanwhile, due to a guide function of the retainer, the axial force of the full needle bearing is greatly reduced, the service life of the full needle bearing is prolonged, and the application range of the full needle bearing is widened.
Description
Technical field
The utility model relates to bearing machining design field, particularly a kind of full pin punching press needle bearing with retainer.
Background technique
Full needle bearing because of its load large, there is very large market in some bearing use fields, but because full needle shaft bears inner space restriction, its structural type is the structure of not being with retainer, its needle roller often adopts prong structure purl or limits flat pin needle roller with grease, plastic sleeve and assemble the pin that falls in front and transportation process, there is certain risk, simultaneously because needle roller does not guide, in rotation, there is larger axial force, life-span and rotating speed to bearing all have a great impact, and have limited the use of bearing.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of full pin punching press needle bearing with retainer, can keep the load carrying capacity of full needle bearing constant, can eliminate needle roller again and fall the shortcoming of pin, can guide needle roller motion, reduce axial force and improve the completely rotating speed of needle bearing simultaneously.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of full pin punching press needle bearing with retainer, comprise bearing outer ring, needle roller and retainer, described needle roller is evenly covered with in the raceway of bearing outer ring, form full needle construction, described retainer is located in described bearing outer ring, retainer is provided with the internal lock pin hole equating with needle roller quantity, in each internal lock pin hole, there is the needle roller described in, so that described needle roller is fixed, the both sides of described retainer have respectively a rib, the crossbeam of retainer adopts the structure lower than needle roller center-diameter.
Further, described retainer is the plastic cage that PA46 material is made.
Further, between described adjacent needle roller, contact with each other.
The beneficial effects of the utility model are: in full pin punching press needle bearing of the present utility model, be provided with the retainer not having in general completely needle bearing, retainer is provided with internal lock pin hole, mode by Inner locking needle is fixed needle roller, in keeping the high bearing capacity of full needle bearing, in the full needle bearing of solution, needle roller falls the problem of pin, improve the reliability of the installation of bearing, the guiding function of retainer also makes the axial force of full needle bearing obtain very large reducing simultaneously, has improved life-span and the using scope of full needle bearing.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model with the full pin punching press needle bearing of retainer.
Fig. 2 is the structural representation of the utility model with retainer in the full pin punching press needle bearing of retainer.
Fig. 3 is the sectional view along A-A line in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As depicted in figs. 1 and 2, a kind of full pin punching press needle bearing with retainer, comprise bearing outer ring 1, needle roller 2 and retainer 3, described needle roller 2 is evenly covered with in the raceway of bearing outer ring 1, forms full needle construction, between adjacent needle roller 2, contacts with each other, described retainer 3 is located in described bearing outer ring 1, retainer 3 is provided with the internal lock pin hole equating with needle roller 2 quantity, has the needle roller 2 described in each internal lock pin hole, thereby realizes internal lock pin hole the fixing needle roller 2 of retainer.As shown in Figure 3, the both sides of described retainer 3 have respectively a rib.The crossbeam of retainer 3 adopts the structure lower than the center-diameter of needle roller 2.Retainer 3 in the utility model is fixed needle roller 2 by the mode of Inner locking needle, has solved needle roller in full needle bearing and fall the problem of pin, has improved the reliability of the installation of bearing.
The plastic cage that retainer 3 is made for PA46 material, can solve the problem of meticulous, the weak strength that retainer lintel exists, and improves the technology capability of retainer, has also improved intensity and the resistance to high temperature of retainer.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (3)
