Abstract
The utility model relates to a cylindrical roller bearing. The cylindrical roller bearing comprises a holder and a roller, wherein the roller can be arranged in a roller slot of the holder in a free rolling manner by virtue of a plurality of cylindrical rollers; and an oil slot is arranged on the inner surface of the roller slot. The cylindrical roller bearing is simple, compact and reasonable in structure, low in manufacturing cost, flexible to rotate, capable of lowering noises, capable of improving the bearing capacity of the bearing and capable of prolonging the service life.
Description
Technical field
The utility model relates to a kind of roller bearing.
Background technique
In the prior art, bearing is divided into tapered roller bearing, roller bearing and ball bearing, every kind of bearing has different functions when equipment uses, as axial load resistant, anti-radial load or anti-axially and connected load radially or sliding friction changed into rolling friction, according to the required type of bearing and the size of size selected of different working environments, wherein use comparatively extensive with roller bearing again, when equipment uses, because long meeting running time causes bearing heating, according to expand with heat and contract with cold former comprehend deform, make it dumb in rotation process, thereby equipment integral body is caused harmful effect, and precision is low, and bearing capacity is poor, and working life is short.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of product precision height, bearing capacity by force and the roller bearing that increases the service life significantly.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of roller bearing, have retainer and roller, can the free rolling mode being arranged in the roller groove of retainer, the internal surface of roller groove offers oil groove to roller by a plurality of cylindrical rollers.
Further, described retainer is made by synthetic resin.
Further, described oil groove is arranged on the angle position of roller groove.
Width and the diameter ratio of the bearing profile that forms after further, described roller is arranged on the retainer are 0.7～2.6.
The beneficial effects of the utility model are: the utility model is simple in structure, compact, reasonable, and low cost of manufacture is rotated flexibly, can be reduced noise, has improved the bearing capacity of bearing, and length increases the service life.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. retainers among the figure, 2. roller, 3. roller groove, 4. oil groove.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of roller bearing as shown in Figure 1, have retainer 1 and roller 2, roller 2 by a plurality of cylindrical rollers can the free rolling mode being arranged in the roller groove 3 of retainer 1, retainer 1 is made by synthetic resin, the internal surface of roller groove 3 offers oil groove 4, oil groove 4 is arranged on the angle position of roller groove 3, and width and diameter ratio that roller 2 is arranged on the bearing profile that the back forms on the retainer 1 are 0.7～2.6.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
