Abstract
A bushing locating device for an oil film bearing relates to an oil film bearing, and solves the technical problems that the conventional bushing locating device has an oil leakage hidden danger and a locating pin affects oil feeding smoothness. The bushing locating device for the oil film bearing is characterized in that the bushing cancels a flange; a flange type locating ring is added at one end of the bushing and between a bearing seat and the bushing; four symmetrical plum-blossom shaped bosses are arranged in inner holes of the flange type locating ring; four plum-blossom shaped grooves matched with the bosses are formed on an excircle at one end of the bushing; and the flange type locating ring is axially fastened with the bearing seat by a flange and radially fastened with the bushing by a bolt. When used for the oil film bearing, the bushing locating device not only can locate the bushing axially and radially, but also effectively overcomes the oil leakage phenomenon of the conventional bushing locating pin, optimizes an oil feeding system of the oil film bearing, and prolongs the service life of the oil film bearing.
Description
Technical field
The present invention relates to filmatic bearing, particularly the improvement of filmatic bearing liner positioning device.
Background technique
Filmatic bearing is high-accuracy sliding bearing, is usually used on operation roll of mill or support roll, utilizes the gap between tapered sleeve and lining to form rational oil film wedge and carries out work.When tapered sleeve rotates together with roll, the lubricant oil with certain viscosity is constantly entrainmented in the wedge gap between tapered sleeve and lining, forms oil film to bear the rolling loads of milling train.Define complete pressure film on the surface of axle and bearing, two friction surfaces are separated completely, any Metal Contact does not occur.Filmatic bearing lining loads inner hole of bearing seat, and is provided with positioning device constraint lining and the relatively rotating of bearing support.
Existing filmatic bearing liner positioning device, as shown in Figure 1, 2.Comprise: bearing support 1, lining 2, tapered sleeve 3, during installation, lining locating stud 4 is inserted the pin-and-hole of lining 2 from bearing support 1 outside, fastening with screw, packing ring, sealing, realize the radial location of bearing support and lining, prevent lining and bearing support from relatively rotating; And by lining flange 2-1 axially locating, prevent lining from moving axially.The shortcoming that existing filmatic bearing liner positioning device exists is: as there is screw loosening, seal failure, and there is the hidden danger of leakage of oil at this place, assembles trouble simultaneously; Lining 2 oil-feed district designs some through holes, as oil inlet hole, owing to by certain oil inlet hole of lining side, in order to mounting bush locating stud 4, will have a certain impact to the oil-feed of filmatic bearing is unobstructed when filmatic bearing is assembled.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, a kind of filmatic bearing liner positioning device is provided, solve that existing liner positioning device exists leakage of oil hidden danger, locating stud affects the unobstructed technical problem of oil-feed.
The present invention is achieved by the following technical solutions:
A kind of filmatic bearing liner positioning device, comprise: bearing support, and the lining to be connected with bearing support, it is characterized in that: described lining eliminates flange, a flange-type positioning ring is set up in one end of described lining, between described bearing support and described lining, the endoporus of described flange-type positioning ring is provided with four symmetrical petal-shaped boss of plum, one end cylindrical of described lining is processed with four the petal-shaped grooves of plum matched with described boss; Described flange-type positioning ring is axially fastened by flange and described bearing support, described flange-type positioning ring screw and described lining radial direction fastening.
Further, in wherein two symmetrical grooves of four described grooves, processing is used for the tapped hole fastening with flange-type positioning ring respectively.
Further, described gasket end is provided with lifting eye.
The present invention compared with prior art, due to the one end at lining, between bearing support and lining, set up flange-type positioning ring, and be provided with the boss with the fit depressions on lining at flange-type positioning ring endoporus, therefore, it is possible to realize lining axis and radial location.Meanwhile, owing to eliminating dynamic pressure oil inlet hole mounting bush locating pin structure, both saved bearing support pin-and-hole, do not taken dynamic pressure oil inlet hole again, and made lining oil-feed more unobstructed.Because lining cannot be blue, material and processing cost are saved.Flange-type positioning ring is as individual part, and can continue to use, the life-span not by lining limits.The present invention is used for filmatic bearing, not only can realize axis and the radial location of lining, and effectively overcome existing lining locating stud oil leakage phenomenon, and optimize filmatic bearing oil feeding system, improve the working life of filmatic bearing.

Embodiment
As shown in Fig. 3,4,5,6, a kind of filmatic bearing liner positioning device, comprise: bearing support 1, and the lining 2 to be connected with bearing support, described lining 2 eliminates flange, in one end of described lining 2, between described bearing support 1 and described lining 2, set up a flange-type positioning ring 5, described flange-type positioning ring 5 endoporus is provided with four symmetrical petal-shaped boss 5-1 of plum, one end cylindrical of described lining 2 is processed with the petal-shaped groove 2-2 of four plums matched with described boss 5-1; Described flange-type positioning ring 5 is axially fastened by flange and described bearing support 1, and described flange-type positioning ring 5 is fastening with described lining 2 radial direction with screw.Lining 2 axially firmly compresses by described flange-type positioning ring 5; The radial direction of described lining 2 limits it by described boss 5-1, groove 2-2 cooperation and rotates.
In wherein two symmetrical grooves of four described groove 2-2, processing is used for the tapped hole fastening with flange-type positioning ring 5 respectively.
The end of described lining 2 is provided with lifting eye.
Installation process of the present invention:
First by flange-type positioning ring 5 and lining 2 screw fastening, then integral hoisting, load in bearing support 1, adjustment boss 5-1 position, then fastening with bearing support 1.
The present invention cancels lining flange design, lining 2 Excircle machining is become four petal-shaped grooves of plum, and increase a flange-type positioning ring 5, flange-type positioning ring 5 endoporus is processed into four petal-shaped boss of plum, with excircle of bushing fit depressions simultaneously.Two screws by flange-type positioning ring 5 tight on bearing support 1, two screws and lining 2 are tight.Plum blossom lobe boss, groove carry out radial location to lining, axially compress by flange-type positioning ring 5.
