Abstract
The utility model discloses a metallic matrix inserted self-lubricating thrust force and angular contact spherical plain bearing belonging to the bearing technology field, in particular to a heavy-duty thrust force and angular contact spherical plain bearing. The utility model is characterized in that a plurality of blind holes are provided on the inner ring and outer ring of the metal substrate, and on the outer spherical surface of the inner ring of the steel substrate or / and the inner spherical surface of the outer ring of the steel substrate, the inner ring of the steel substrate and the outer ring of the steel substrate are engaged with each other, the solid lubricant is inlaid in the blind hole, and the inlaid positions on the outer spherical surface of the inner ring of the steel substrate and the inlaid positions on the inner spherical surface of the outer ring of the steel substrate are alternatively arranged. The utility model has reasonable design and reasonable and compact structure, the solid lubricant embedded in the contact face of the inner-and-outer of the bearing is adequately distributed, with the moving of coupled parts gradually expanding, no matter that the friction surface is big or small, and the friction velocity is fast or low, the bearing is capable of operating stably and has low abrasion and high life.
Description
Technical field
The utility model belongs to technical field of bearings, relates in particular to thrust, the angular contact articulated bearing of heavy load.
Background technique
Along with China's industrial automation fast development, main equipment is increasing, and particularly metallurgy industry is more and more higher for the requirement of the thrust articulated bearing of heavy load and angular contact articulated bearing.Because this class bearing load is heavy, oiling is difficult to put in place, and employing is pasted solid yarn fabric lubriation material and broken away from easily, and therefore, this type of bearing operation is not steady in the prior art, and wearing and tearing are big, and the life-span is low.
The model utility content
Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model provides a kind of metal base inlaid type selflubricating thrust, angular contact articulated bearing, solid lubricant is embedded on the surface of contact of Internal and external cycle of (imbedding) bearing, can guarantee the running of thrust articulated bearing and angular contact articulated bearing steadily, it is low to wear and tear, and the life-span is long.
The technical solution of the utility model is: this metal base inlaid type selflubricating thrust, angular contact articulated bearing, inner ring and the outer ring of containing metal base, the outer spherical surface of the metal base inner ring that cooperatively interacts is inlaid with solid lubricant or/and the inner ball surface of metal base outer ring is provided with a plurality of blind holes in the blind hole.The mosaic point of described solid lubricant on the inner ball surface of mosaic point on the outer spherical surface of metal base inner ring and metal base outer ring is evenly to arrange.When described solid lubricant was embedded on the inner ball surface of the outer spherical surface of metal base inner ring and metal base outer ring simultaneously, the mosaic point on the inside and outside spherical surface was that dislocation is arranged.
The utility model is reasonable in design, rational in infrastructure simple and direct, solid lubricant is imbedded on the surface of contact of bearing enclose and can not come off, solid lubricant is evenly distributed, and can launch along with mating plate move gradually, no matter the rubbing surface of mating plate is big or little, and fricting movement speed is fast or slow, the running that can both guarantee bearing is steady, low wearing and tearing and long-life.
Description of drawings
Accompanying drawing 1 is embodiment's thrust articulated bearing structural representation;
Accompanying drawing 2 is another embodiment's angular contact articulated bearing structural representation;
Accompanying drawing 3 is embodiment's joint shaft bearing structural representation of cases of otherwise standard design.
Accompanying drawing acceptance of the bid keep the score state as follows: the 1-inner ring; The 2-outer ring; The 3-oiling agent; The 4-oil hole; The 5-fitting recess.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.Angular contact articulated bearing and thrust articulated bearing are same class bearings, difference to some extent on application area only, generally speaking, the nominal contact angle of angle contacting thrust articulated bearing is spent less than 90 greater than 30 degree, be suitable for bearing thrust load, also can bear connected load, but this moment, its radial load must not be greater than 0.5 times of thrust load.The nominal contact angle of thrust articulated bearing is 90 degree, is suitable for bearing thrust load, can not bear radial load.Be embodiment's thrust articulated bearing of the present utility model shown in the accompanying drawing 1, in diagram, all be provided with a plurality of blind holes on the inner ball surface of the outer spherical surface of inner ring 1 and outer ring 2, be inlaid with solid lubricant 3 in the blind hole.In the present embodiment, also can be only on the inner ball surface of the outer spherical surface of inner ring 1 or outer ring 2, blind hole be set, inlaid solid lubrication agent 3 in blind hole.Be embodiment's angular contact articulated bearing of the present utility model shown in the accompanying drawing 2, in diagram, all be provided with a plurality of blind holes on the inner ball surface of the outer spherical surface of inner ring 1 and outer ring 2, be inlaid with solid lubricant 3 in the blind hole.In the present embodiment, also can be only on the inner ball surface of the outer spherical surface of inner ring 1 or outer ring 2, blind hole be set, inlaid solid lubrication agent 3 in blind hole.Accompanying drawing 3 is joint shaft bearings of the utility model embodiment's cases of otherwise standard design, except the nonstandard design of structure, has also increased oil hole 4 and fitting recess 5, in addition, and can also be according to actual needs and area of contact that may increase or reduce Internal and external cycle etc.Above accompanying drawing is not to be whole protection domains only for the content of technological scheme is described.Joint shaft bearing of the present utility model, according to the difference of load, can select alloyed steel, alloyed copper for use is basic material, the combination of materials of Internal and external cycle can be that steel to steel or steel are to copper.The utility model bearing of nonstandard design can increase the oilhole oil groove according to user's actual demand, and the mount device etc.
