Abstract
The utility model discloses a novel four-oil-wedge bearing bush which has the advantages that the processing is convenient, and the service life is long, and comprises an upper bearing bush and a lower bearing bush, wherein the upper bearing bush is combined and connected with the lower bearing bush through a mounting bolt and a locating pin; four through grooves are formed in the upper bearing bush and the lower bearing bush in the axial directions respectively; tension bolts are arranged at the peripheries of the upper bearing bush and the lower bearing bush. The novel four-oil-wedge bearing bush provided by the utility model is processed conveniently.
Description
Technical field
The utility model belongs to the technical field of bearings of machinery, relates in particular to a kind of novel four oil Wedge Bushs.
Background technique
As everyone knows, four oil Wedge Bushs are compared the cylinder bearing shell stability characteristic (quality) preferably, compares tilting type bearing bush and has again load-carrying properties preferably, therefore by rotating machineries such as high-speed gear boxes, is extensively adopted.Existing four oil Wedge Bush cylindricals coordinate location with casing, endoporus is provided with four protruding oil film wedges axisymmetricly, and cross section is half moon, described crescent shape curve and cylindrical centre distance be etc. add or etc. subtract.Due to this Curve Machining process complexity, therefore cause into cost of production also higher.And, because existing bearing shell endoporus difficulty of processing is large, surface roughness is also undesirable, thereby to also exerting a certain influence the working life of product.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of novel four oil Wedge Bushs of easy to process, long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises top bearing shell, lower bearing, and described top bearing shell and lower bearing are connected and are formed by construction bolt and locating stud, and described top bearing shell and lower bearing axially are respectively equipped with four grooves, and described top bearing shell and lower bearing periphery are provided with turnbuckle.
Because the utility model top bearing shell and lower bearing axially are respectively equipped with four grooves, and make watt body produce distortion by turnbuckle, form four crescent shape oil film wedges, thereby make bearing shell processing simple, manufacturing efficiency improves, and saved cost of production, and inner bore surface roughness and radiating effect are preferably arranged, improved working life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is mounting structure schematic diagram of the present utility model.
In figure: 1, turnbuckle; 2, groove; 3, top bearing shell; 4, construction bolt; 5, lower bearing; 6, locating stud.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
As shown in Figure 1 and Figure 2: the utility model comprises top bearing shell 3, lower bearing 5, top bearing shell 3 is connected and is formed by construction bolt 4 and locating stud 6 with lower bearing 5, top bearing shell 3 axially is respectively equipped with four grooves 2 with lower bearing 5, and top bearing shell 3 is provided with turnbuckle 1 with lower bearing 5 peripheries.
The utility model is adding man-hour, groove 2 cuts top bearing shell 3, lower bearing 5 is divided into to inside and outside two parts that are connected by line, connected inside is arranged with two boss and fits by turnbuckle 1 with the outer part be connected, thereby make bearing shell obtain four crescent shape oil film wedges, and the gap that the part that fits is removed is crescent shape oil groove gap.Owing to adopting said structure, the bearing shell endoporus can process at one time, so endoporus has surface roughness preferably; The setting of groove 2 increases the bearing shell external surface area, is conducive to the bearing shell heat radiation; Oil film wedge is formed by a watt body deformability, has curvature preferably, has not only met designing requirement, and manufacturing efficiency is improved.
