Abstract
The utility model relates to a nonmetallic cage of needle roller bearings. The cage comprises a ring-shaped frame, wherein a plurality of needle roller pockets are distributed on the ring-shaped frame along the circumferential surface thereof; pocket lintels are arranged between the needle roller pockets; and a concave oil groove with noncommunicating end surfaces is formed on the outer wall of each pocket lintel. The concave oil groove on the outer wall of each pocket lintel is utilized to store part of oil, so that in the case of no oil passing through a gear oil channel, the oil stored in the cage oil grooves can maintain the lubricating property of the cage, thereby remaining the friction force during the movement of the needle roller bearing and improving the service life of the needle roller bearing.
Description
Technical field
The utility model relates to a kind of nonmetal retainer of needle bearing, belongs to nylon bearing retainer technical field.
Background technique
Being used for the interior people's needle bearing of automobile-used gearbox is installed between driving gear and the transmission shaft usually, needle bearing cage, mainly constitute along the uniform some needle roller pockets of circumferential surface hole by annular frame and annular frame, needle roller is installed in each needle roller pocket hole, contacts with transmission shaft with driving gear respectively by needle roller.Lubricant oil during work in the gearbox casing enters in the needle bearing be introduced into oil duct on the gear by splashing after again, with the needle roller pocket hole that reduces needle roller and retainer and the frictional force between driving gear and the transmission shaft.But because of the perisporium of retainer does not all have oil groove, in case the fluid in the gear-box can not in time enter in the needle bearing waiting in particular cases as going up a slope, easily increase the kinetic friction force of needle bearing, cause noise and heating, also can damage retainer when serious, and shorten the working life of needle bearing.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned technology, and a kind of nonmetal retainer that improves the needle bearing of needle bearing greasy property is provided.
The utility model is the technological scheme that achieves the above object: a kind of nonmetal retainer of needle bearing, comprise annular frame, annular frame is along the uniform some needle roller pockets of circumferential surface hole, have pocket hole lintel between each needle roller pocket hole, it is characterized in that: have the indent oil groove that both ends of the surface do not connect on the outer wall of described each pocket hole lintel.
The utility model has the indent oil groove on the outer wall of each pocket hole lintel, when lubricant oil enters in the needle bearing by entering oil duct on the gear after splashing again, can pass through several indent oil groove storage area fluid, even if when not having fluid to enter the oil duct of gear, can be by being stored in the fluid in the retainer indent oil groove, and keep the greasy property of retainer, and make the needle bearing kinetic friction force constant, can improve the working life of needle bearing.
Description of drawings
Below in conjunction with accompanying drawing the example that relates to of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic representation of Fig. 1.
Fig. 3 is the B place structure for amplifying schematic representation of Fig. 2
Wherein: 1-annular frame, 2-needle roller pocket hole, 3-pocket hole lintel, 4-indent oil groove.
Embodiment
Shown in Fig. 1～3, the nonmetal retainer of needle bearing of the present utility model, comprise annular frame 1, annular frame 1 is along the uniform some needle roller pockets of circumferential surface hole 2, has pocket hole lintel 3 between adjacent each needle roller pocket hole 2, needle bearing cage adopts engineering plastics to make, see Fig. 2, shown in 3, has the indent oil groove 4 that both ends of the surface do not connect on the outer wall of each pocket hole lintel 3, this indent oil groove 4 is a curve bath, but by these indent oil groove 4 storage area fluid, has good lubricating property to keep needle bearing, to reduce the motion frictional resistance, improve the working life of needle bearing.
Claims (2)
1, a kind of nonmetal retainer of needle bearing, comprise annular frame (1), annular frame (1) is along circumferential surface uniform some needle roller pockets holes (2), have pocket hole lintel (3) between adjacent each needle roller pocket hole (2), it is characterized in that: have the indent oil groove (4) that both ends of the surface do not connect on the outer wall of described each pocket hole lintel (3).
2, the nonmetal retainer of needle bearing according to claim 1 is characterized in that: described indent oil groove (4) is a curve bath.
