Abstract
The utility model relates to a rolling body provided with extension posts at the two ends. The rolling body (2) is cylindrical and is characterized in that the extension posts (1) are respectively arranged on end surfaces of the two ends of the rolling body (2), the diameter of each of the extension posts (1) is smaller than that of the rolling body, and the extension posts (1) are cylindrical and are respectively arranged at central positions of the end surfaces of the two ends of the cylindrical rolling body (2). In the rolling body provided with the extension posts at the two ends provided by the utility model, the extension posts at the two ends of the rolling body are respectively inserted into penetrating holes of two annular retainers, thereby avoiding the contact of the rotation stress area of the cylindrical excircle of the rolling body and the retainers, preventing the contact abrasion of the surface of the excircle of the rolling body and the retainers, and effectively improving the use time of the rolling body.
Description
Technical field
The utility model relates to a kind of rolling element, especially relates to the rolling element that a kind of two ends have extending column.
Background technique
Known, the radial dimension of rolling bearing is bigger, and damping capacity is relatively poor, during high speed the life-span low, the sound is bigger.Radial bearing in the rolling bearing (main bearing radial force) is made up of inner ring, outer ring, rolling element and roller holder four parts usually.Inner ring tightly is enclosed within on the axle journal and rotates together with the axis, and the outer ring is contained in the bearing saddle bore.Be shaped on raceway in the periphery of inner ring and the interior Zhou Shangjun of outer ring.When Internal and external cycle relatively rotated, rolling element promptly rolled on the raceway of Internal and external cycle, and rolling element is separated by retainer, avoided the phase mutual friction; But the friction of retainer and rolling element just can't overcome; Because the sliding friction of rolling element must cause the heating and the wearing and tearing of bearing roller; Especially under the high temperature operation condition; The effect of inertial centrifugal force has aggravated friction, wearing and tearing and heating, can cause retainer burn or fracture when serious, causes the bearing cisco unity malfunction.Therefore, for the architecture advances of retainer, and the architecture advances of rolling element becomes inevitablely, so that force the rotation stress surface of the cylinder cylindrical of rolling element can not wear and tear by secondary with retainer, alleviates the friction factor of rolling element.
Summary of the invention
In order to overcome the deficiency in the background technique, the utility model discloses the rolling element that a kind of two ends have extending column, prevent the contact wear of rolling element periphery and retainer, improve the service time of rolling element effectively.
For realizing the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of two ends have the rolling element of extending column; Rolling element is cylindrical; The extending column of diameter less than the rolling element diameter is set respectively on the end face of the two ends of rolling element, and described extending column is cylindrical and is separately positioned on the central position of cylindrical rolling element two ends end face.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
The utility model discloses a kind of two ends and have the rolling element of extending column; Through on the end face at rolling element two ends, extending column being set; Insert the perforation of inside and outside two annular retainers respectively by the extending column that is positioned at the rolling element two ends; Prevented the contact wear of rolling element periphery and retainer, the service time of having improved rolling element effectively; The utlity model has advantages such as simple in structure, that load-bearing strength is big, service time is long.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, extending column, 2, rolling element.
Embodiment
Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope;
As shown in Figure 1; A kind of two ends have the rolling element of extending column; Rolling element 2 is cylindrical, and the extending column 1 of diameter less than the rolling element diameter is set respectively on the end face of the two ends of rolling element 2, and described extending column 1 is cylindrical and is separately positioned on the central position of cylindrical rolling element 2 two ends end faces.
Implement the utility model in conjunction with accompanying drawing 1; Difference extending column 1 on the end face at rolling element 2 two ends; Insert the perforation of inside and outside two annular retainers respectively by the extending column that is positioned at the rolling element two ends 1; Avoided the rotation stress surface of rolling element 2 cylindricals to contact, prevented the contact wear of rolling element 2 peripheries and annular retainer, the service time of having improved rolling element effectively with annular retainer.
Claims (1)
1. two ends have the rolling element of extending column; Rolling element (2) is cylindrical; It is characterized in that: the extending column (1) of diameter less than the rolling element diameter is set respectively on the two ends end face of rolling element (2), and described extending column (1) is cylindrical and is separately positioned on the central position of cylindrical rolling element (2) two ends end face.
