Abstract
The utility model relates to a bearing and processing technology thereof. The bearing comprises a bearing outer ring 1 and an inner ring 2. In order to convenient maintenance and service of the bearing and the enhancement of the anti-wear performance of the bearing, a self-lubricating material liner 3 is pasted on the working surface of the bearing outer ring 1. The liner is in a press forming after unloading modification high molecular plastics, or dual metal, or copper alloy, or three-layer composite materials inlaid on solid lubricant and a metal base. A structure, the inner spherical surface of the outer ring of which is an annular spherical surface, is designed, the structure is favorable to the installation and the paste of the self-lubricating material liner, and the liner keeps firm at work. The structure does not need to be lubricated by adding oil at work, and the maintenance and the service are convenient. The outer spherical surface of the inner ring is plated with an anti-wear layer. Self-lubricating materials can reduce the wear of the bearing at work, the anti-wear layer improves the anti-wear performance of the bearing, thereby, the service life of the bearing is improved.
Description
Technical field the present invention relates to a kind of bearing and processing technique thereof, specifically, relates to a kind of angular contact articulated bearing and processing technique thereof.
In the existing angular contact articulated bearing of background technique, bearing is made up of inner ring, outer ring.The surface that Internal and external cycle cooperatively interacts is a working surface, constitutes a pair of friction pair.The working surface of outer ring is an inner ball surface, and the working surface of inner ring is an outer spherical surface.The friction pair of working surface is the steel to steel pattern.Usually steel to steel friction pattern is processed with oil groove on the inner ball surface of outer ring, and the reply bearing carries out oilyly in the working procedure, and steel to steel friction type ratio is easier to wearing and tearing.
Model utility content the purpose of this utility model provides a kind of self-lubricating knuckle bearing, and this bearing can overcome the inconvenient at work oily situation of lubrication type angular contact articulated bearing, has high wear resistance again.
For achieving the above object, the technological scheme that the utility model provides is: bearing is made up of inner ring and outer ring, and the surface that Internal and external cycle cooperatively interacts is a working surface, constitutes a pair of friction pair.The working surface of outer ring is an inner ball surface, and the working surface of inner ring is an outer spherical surface, it is characterized in that: increase one deck self lubricating material liner in the outer ring inner ball surface, constitute the friction pattern of steel to self lubricating material.The outer ring inner ball surface is processed as the inner ball surface groove, and rib is left in close both ends of the surface position, and the embedding of self lubricating material liner is sticked in the groove.The self lubricating material liner is made for the 3-layer composite material that is contained solid lubricant, metal by modified high-molecular plastics, metal or Cuprum alloy, and liner has antifriction function to inner ring at work.Simultaneously, the inner ring outer spherical surface plates high-abrasive material, strengthens the wear resistance of bearing.
The beneficial effects of the utility model are that the embedding of self lubricating material liner sticks in the groove, and structure is more firm.Needn't be oily in the bearing working process, maintaining is more convenient.Utilize self lubricating material to be lubricated, can reduce the wearing and tearing of bearing at work, and the inner ring outer spherical surface plates high-abrasive material, the wear resistance of enhancing bearing, thereby the working life of improving bearing.This airframe bearing is applicable to and bears radially and axial connected load.
Description of drawings Fig. 1 is the structure sectional view of the utility model self-lubricating knuckle bearing.Mark 1-outer ring, 2-inner ring, 3-self lubricating material liner among the figure.Fig. 2 is the parts drawing of the utility model self-lubricating knuckle bearing outer ring.Mark 11-outer ring inner ball surface groove among the figure.
Embodiment as shown in Figure 1, the utility model comprises outer ring 1, inner ring 2.Inner ball surface is processed with spherical groove in the outer ring, as 11 among Fig. 2,3 embeddings of self lubricating material liner is sticked in the groove.Simultaneously, the outer spherical surface of inner ring 2 plates wearing layer.Paste firmly with liner 3 outer ring 1, does not have relative movement, and liner 3 and inner ring 2 slide relative constitute steel and self lubricating material friction pair.
Claims (2)
