Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of roller bearing.
Background technique
In roller bearing, the raceway of inner ring and roller are because be linear contact lay, therefore larger radial load can be born, the baffle plate of inner ring and roller end face are plane contact, when bearing needs to hold the certain bearing load of hand, very close to each other between the baffle plate of inner ring and roller end face, lubricant oil is difficult to enter between baffle plate and roller, when stress between roller end face and baffle plate is too large, probably causes temperature to rise, burn.
Model utility content
The technical problems to be solved in the utility model is: it is very close to each other that the end face in order to the inner ring baffle plate with roller that solve roller bearing in prior art contacts because of end thrust, lubricant oil cannot enter between them, cause the problem that temperature rises, burns, the utility model provides a kind of roller bearing and solves the problems referred to above.
The utility model solves the technological scheme that its technical problem adopts: a kind of roller bearing, comprises outer ring, inner ring and be arranged on the multiple rollers between described outer ring and inner ring, and the diameter length of described roller is 30 ~ 40mm;
The side of described roller is transitioned into both ends of the surface respectively by a directed section, the surface of described directed section is made up of several continuous print first circumference, on the central shaft that described roller is all dropped in the center of circle of several the first circumference described and several the first circumference place planes described all perpendicular to described central shaft, several first circumference described are the end face of circular arc described roller for path extends to of 2700 ~ 3750mm with radius from the side of described roller, and described circular arc evagination is in described roller;
The end of described inner ring has rib, described rib has guide portion, the surface of described guide portion is made up of several continuous print second circumference, the circle of several the second circumference described all to drop on described central shaft and several the second circumference place planes described all perpendicular to described central shaft, several second circumference described take straight line as path extends to close described inner ring near central shaft side raceway side from described guide portion, described straight line is less than the distance of described straight line at the end of central shaft side and the middle part radial cross section of described roller in the distance of the end of described raceway side and the middle part radial cross section of described roller, the radial direction of described straight line and described roller forms acute angle theta, wherein 10 '≤θ≤60 '.
Concrete, the stress point of described guide portion and directed section and the distance of described raceway are 2.8 ~ 3.7mm.
As preferably, the radius of described circular arc is 3278mm, and described roller diameter is 35mm, described acute angle theta=15 '.
The beneficial effects of the utility model are, this roller bearing is provided with guide portion on inner ring rib, the end face of roller is provided with directed section, gap is there is in guide portion after contacting under the effect of thrust with directed section, lubricant oil can enter between them, can not cause overheated and burn.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the optimum embodiment of the utility model roller bearing.
In figure 1, inner ring, 2, roller, 3, guide portion, 4, directed section.
