Abstract
The utility model discloses a roller for a self-aligning roller bearing. The roller is shaped as a cylinder. Two ends of the cylinder are provided with a process counter bore with the same shape respectively. The surface of the cylinder is provided with a carburized layer. The roller for the self-aligning roller bearing is made from high-quality alloy steel. The depth of the carburized layer is 2 to 2.5 millimeters. The depth of the process counter bores is 3 millimeters. Due to the structure adopted by the roller for the self-aligning roller bearing, the surface hardness of the roller is improved, the rated load of the self-aligning roller bearing with the same overall dimension can be enhanced, and further the occupied area of a bearing block can be reduced under the condition of meeting the harsh using requirements of heavy load and impact occasions.
Description
Technical field
The utility model relates to bearing, relates in particular to a kind of selfaligning roller bearing roller.
Background technique
Selfaligning roller bearing is commonly used in heavy duty and the workplace of aligning performance requirement is arranged, selfaligning roller bearing comprises outer ring, inner ring, roller, under the restriction in certain boundary dimension space, can only pack into the roller of suitable quantity of selfaligning roller bearing, the roller size is restricted, the selfaligning roller bearing use of roller at present, the bearing rated load is main relevant with the roller size with the quantity of roller, in order to satisfy heavy duty and to impact the harsh usage requirement of occasion, the boundary dimension of the selfaligning roller bearing of selecting for use needs bigger, and it is also bigger that corresponding bearing support takies volume.
The model utility content
Technical problem to be solved in the utility model is: a kind of selfaligning roller bearing roller is provided, this kind selfaligning roller bearing can guarantee that with the use of roller selfaligning roller bearing improves rated load under identical boundary dimension, thereby can reduce the volume that takies of bearing support under the harsh usage requirement of satisfying heavy duty and impact occasion.
Solve this technical problem, the technical solution of the utility model is: a kind of selfaligning roller bearing roller, be shaped as cylindrical body, and described cylindrical two ends have identical shaped technology counterbore respectively, and described cylindrical surface has carburized case.
Described selfaligning roller bearing is a superior alloy steel with the material of roller, and carburized layer depth is 2～2.5 millimeters.
The degree of depth of described technology counterbore is 3 millimeters.
A kind of selfaligning roller bearing of the utility model adopts such structure with roller, the surface hardness of roller is improved, can guarantee that selfaligning roller bearing improves rated load under identical boundary dimension, thereby under the harsh usage requirement of satisfying heavy duty and impact occasion, can reduce the volume that takies of bearing support.
Description of drawings
Below in conjunction with accompanying drawing a kind of selfaligning roller bearing of the utility model is done explanation in further detail with roller;
Fig. 1 is the structural representation of a kind of selfaligning roller bearing of the utility model with roller;
In Fig. 1,1, carburized case; 2, technology counterbore.
Embodiment
As shown in Figure 1, the selfaligning roller bearing roller, be shaped as cylindrical body, cylindrical two ends have identical shaped technology counterbore 2 respectively, described cylindrical surface has carburized case 1, the selfaligning roller bearing material selection 20Cr2Ni4A of roller, carburized case 1 is 2～2.5 millimeters deeply, the degree of depth of described technology counterbore 2 is 3 millimeters.Such structure, the surface hardness of roller is improved, and can guarantee that selfaligning roller bearing improves rated load under identical boundary dimension, thereby can reduce the volume that takies of bearing support under the harsh usage requirement of satisfying heavy duty and impact occasion.
Claims (3)
1. a selfaligning roller bearing roller is shaped as cylindrical body, it is characterized in that: described cylindrical two ends have identical shaped technology counterbore respectively, and described cylindrical surface has carburized case.
2. a kind of selfaligning roller bearing roller according to claim 1 is characterized in that: described selfaligning roller bearing is a superior alloy steel with the material of roller, and carburized layer depth is 2～2.5 millimeters.
3. a kind of selfaligning roller bearing roller according to claim 1 and 2 is characterized in that: the degree of depth of described technology counterbore is 3 millimeters.
