Abstract
The utility model relates to a bearing, in particular to a turbocharger floating bearing, which is provided with a bearing body with cavities. A main cavity in the middle portion of the bearing body is communicated with end cavities at two ends of the bearing body to form an internal cavity of the bearing body; annular grooves are respectively arranged at two end portions of the bearing body; at least one through hole is arranged at the groove bottom of each annular groove; the through hole is communicated with the cavities of the bearing body; a concave surface is arranged in the middle portion of the bearing body; a hole is arranged on the concave surface; and the hole is communicated with the cavities of the bearing body. The turbocharger floating bearing has the advantages of fine lubricating effect and long service life.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of turbosupercharger floating bearing.
Background technique
What adopt between supercharger rotor and the intermediate is two floating bearings, and its structure is that the endoporus at intermediate digs two circlip grooves, loads onto back-up ring in circlip groove earlier, loads onto floating bearing at two ends respectively again, loads onto rotor then.The structure of this floating bearing, because of two ends not in one, and the friction area of floating bearing increases, when the pressurized machine high speed rotating, cause bearing two ends decentraction easily, thereby destroy the balance of rotor, hinder rotor rotation, reduce the life-span and the efficient of pressurized machine, make the assembly technology very complicated of intermediate processing technology and pressurized machine simultaneously, component increase.Now also original two floating bearings of handlebar a kind of integral float shaft of being designed to an integral body holds, it has an inside is the bearing support of cavity, the bearing support internal cavities is formed by connecting by the end chamber at the two end part of the main cavity at the middle part of bearing support, bearing support, but such integral float shaft holds lubricated road, weares and teares easily, working life is not long.
The model utility content
At the problems referred to above, the purpose of this utility model provides a kind of turbosupercharger floating bearing with lubricated road, high lubricating effect.
The realization the technical solution of the utility model is as follows:
The turbosupercharger floating bearing, has bearing support for cavity, the main cavity at bearing support middle part is connected with the end chamber at bearing support two end part and forms the internal cavities of bearing support, described bearing support two end part are provided with annular groove respectively, the bottom land of annular groove has a through hole at least, and through hole is connected with the cavity of bearing support, and described bearing support middle part is provided with concave surface, have the hole on the concave surface, the hole is connected with the cavity of bearing support.
Further, described through hole is evenly distributed in the bottom land of annular groove, when axle rotates, can inject Lubricants in the end chamber from through hole like this in bearing, increases the lubricity between axle and the bearing, reduces friction.
Described main cavity is cylindrical body with the end chamber, and the shape in main cavity, end chamber matches with the shape of axle like this, reasonably arrangement space.
The internal diameter of described main cavity is greater than the internal diameter in chamber, two ends.
Adopt such scheme, offer circular groove at the bearing support two end part, and offer through hole, when machine maintains, can in through hole, in the chamber, two ends, inject Lubricants, increase the lubricity between bearing and the axle, reduce friction, prolong the working life of bearing at bottom land.Compared with prior art, the beneficial effects of the utility model are: high lubricating effect, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the half sectional view of Fig. 1;
In the accompanying drawing, 1 is bearing support, and 2 is main cavity, and 3 are the end chamber, and 4 is through hole, and 5 is the hole, and 6 is annular groove.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1,2, the turbosupercharger floating bearing, has bearing support 1 for cavity, the end chamber 3 that the main cavity that holds a main body 2 at bearing support 1 middle part and bearing support two end part hold shaft end is connected and forms the internal cavities of bearing support, described bearing support two end part are provided with annular groove 6 respectively, the bottom land of annular groove 6 has a through hole 4 at least, through hole 4 is connected with the cavity of bearing support, described bearing support middle part is provided with concave surface, has hole 5 on the concave surface, and hole 5 is connected with the cavity of bearing support, like this when axle rotates, can in the through hole of circular groove 6 groove bottom lands, inject Lubricants, increase the lubricity between axle and the bearing, reduce friction between the two.Be evenly distributed in the bottom land of annular groove 6 as preferred described through hole, can increase lubrication effect like this.The internal diameter of described main cavity is greater than the internal diameter in chamber, two ends.Described main cavity is cylindrical body with the end chamber.
When axle rotated, the frictional force that can produce between axle and the bearing when the two ends of axle are respectively equipped with a bearing, two bearing decentraction because of the support effect of bearing to axle, will cause the imbalance of axle rotation because the existence of frictional force makes; And overall structure of the present utility model, make the two ends of axle keep concentric always, the unbalanced phenomenon of axle rotation can not appear, and the annular groove bottom land is offered through hole at the bearing support two end part, can in the chamber, two ends, add Lubricants by through hole, guarantee the lubricity between bearing and the axle, prolong the working life of bearing.Integrally-built turbosupercharger floating bearing like this installs in the endoporus that also easily only needs its embedding pressurized machine intermediate and gets final product, and can guarantee that this floating bearing is fixed in the endoporus.
