Abstract
The utility model relates to a bearing with high lubricating performance for a vibration sieve, which consists of an outer ring, an inner ring, a roller and a retainer. The bearing is characterized in that the outer ring is provided with a semicircular lubricating oil groove which has effective lubrication with an outer raceway to form an oil film; an oil groove is arranged on the inner track of the inner ring; two arc faces are milled off from two sides of the retainer to form assembling sections; the outer tract of the retainer is a spherical surface; and a section vertical to the centerline of a retainer pocket is arranged on the head face of the retainer pocket, which reduces the inner diameter of the retainer and increases the holding capacity of the retainer. The bearing has the advantages that the retainer guides at the outside; both the inside and the outside can be lubricated; the holding capacity is increased; the problems of burning and unsmooth lubrication during the operation are overcome; and the bearing has the characteristics of friction resistance and vibration resistance and improves the service life of the vibration sieve and the overall quality of the host machine.
Description
Technical field
The utility model belongs to the vibrating screen bearing of design bearing technical field, particularly a kind of high lubricating property, is applied to vibrating sieve and other vibrating machines, belongs to mine and field of metallurgy.
Background technique
Vibrating sieve and vibrating machine have two kinds with bearing at present.A kind of is that retainer is guided by outer raceway, the middle-grade limit of interior astragal structure, and a kind of is that retainer is a CA type structure by the bearing that guides in the shelves limit.Adopt first kind of structure, shortcoming is the retainer and outer raceway frictional heating of outer guiding, and lubricated not smooth, friction is big, often causes outer raceway burn.The user who has is that CA type structure replaces with second kind.When adopting second kind of structure, because vibration is too big, CA type structure can not satisfy the vibrating sieve requirement, and often the life-span does not reach the requirement of main frame family.Developing a kind of vibrating screen bearing thing of novel band high lubricating property retainer must go.
Summary of the invention
The purpose of this utility model just provides a kind of vibrating screen bearing of high lubricating property, retainer is lubricated, the increase containing amount of outer guiding, inside and outside all bands, overcome the running burn, lubricated shortcomings such as smooth, that friction is big, have characteristics such as friction resistant, anti-vibration, improve the vibrating sieve life-span, improved the total quality of main frame.
Technical solution of the present utility model is: a kind of vibrating screen bearing of high lubricating property is made up of outer ring, inner ring, roller and retainer, it is characterized in that, the outer ring is provided with semicircle oil groove, form effective lubricating with outer raceway, form oil film, the inner ring internal diameter has oil groove, forms effective lubricating with inner retaining side, mill off two cambered surfaces in retainer both sides form the assembling cross section, for ease of the part retainer is assembled in the outer ring.The external diameter of retainer is a sphere, coincide with outer spherical surface better, and gap reasonable in design forms guiding with outer raceway, forms oil film.Be provided with the cross section vertical at retainer pocket hole end surface, guarantee that when bore hole boring cutter is vertical with working surface, process more steady with the pocket centerline hole.Cast aside outside the internal diameter that touches with the home record edge joint, dwindle the internal diameter of retainer, increase the containing amount of retainer, make the retainer running steadily.
The beneficial effects of the utility model are, adopt retainer to be guided by outer raceway, and external diameter is a spherical, rationally controls guide clearance.Guarantee to turn round and play guiding function flexibly again.Design several semicircle oil grooves in the inside and outside footpath of retainer, centralized lubrication guarantees that the big shelves of retainer internal diameter and inner ring limit, retainer external diameter form sufficient lubricant film with the guide surface place of outer raceway, prevent the raceway burn.Overcome the running burn, lubricate shortcomings such as smooth, that friction is big, improved the total quality of product.Owing to reach sufficient lubrication, thereby improved the vibrating sieve life-span.Cast aside outside the internal diameter that touches with the home record edge joint, dwindle the retainer internal diameter, increase the containing amount of retainer, make the retainer running steadily.Designed the cross section vertical with the pocket centerline hole at the pocket hole end surface, boring cutter is vertical with working surface when having guaranteed bore hole, has guaranteed the pocket hole location, improves bearing working life.
