Description

A five-watt tilting pad sliding bearing

technical field

The utility model relates to a five-watt tiltable pad sliding bearing.

Background technique

The tilting pad sliding bearing is used to solve the problem of oil film oscillation when the rotor supported by the sliding bearing is running at high speed. The radial sliding bearing with five-watt tilting pad structure is a more commonly used one; In the installation process of the tilting pad sliding bearing, if the structure design of the tilting pad is unreasonable, the distance L between the lower ends of the two tilting pads in the upper half of the sliding bearing is still smaller than the shaft diameter D at the maximum during assembly, and the upper half of the sliding bearing will be in contact with the shaft. interference and cannot be assembled; currently commonly used sliding bearings with an anti-interference structure are shown in Figure 3. A relief structure is processed on the two radially tilting pads on both sides of the upper half of the sliding bearing. The two radially tilting pads The pad can swing to both ends with the pin shaft as the center. At this time, the distance L between the two sides to the lower end of the tilting pad will be larger than the shaft diameter D at the maximum, and the shaft and the sliding bearing can be installed smoothly; but this structure needs to reduce the diameter of the tilting pad. The thickness of the tilting pad reduces the strength of the tilting pad. When the load of the sliding bearing is too large, it may cause the failure of the tilting pad and the processing is inconvenient.

In order to optimize the structure and effect, a further measure is: the number of the tilting pads is five and they are symmetrically distributed inside the bearing body.

The outer arc surface of the tilting pad is connected with the inner arc surface of the bearing body.

One semi-circular ring of the bearing body is provided with three tilting pads, and the other semi-circular ring is provided with two tilting pads.

The utility model is a five-watt tilting pad sliding bearing, which includes a bearing cover, a tilting pad, a cylindrical pin and a bearing body; The bearing caps are arranged on the outer sides of both ends of the bearing body; the bearing body is two semi-circular rings, and the inner circular arc surfaces of the two semi-circular rings are spliced to provide a gap, and the tilting pad can The technical solution is to use the cylindrical pin as the shaft to swing in the gap of the bearing body; it can solve the difficulty of assembling the sliding bearing and the shaft due to the interference of the tilting pad, and at the same time improve the load strength of the bearing; and the overall structure is scientific and reasonable, and the installation and The utility model has the advantages of convenient use, simple production process, low manufacturing cost and easy popularization and use.

Compared with the beneficial effects produced by the prior art, the utility model:

(I) The utility model adopts a gap in the splicing of the inner arc surface of the two semi-circular rings of the bearing body, and the tilting pad can swing and open in the gap of the bearing body with the cylindrical pin as the axis to solve the problem of bearing and shaft. The problem of difficult assembly, and the load strength of the tilting pad is improved, and the processing is simple and convenient;

(II) The utility model adopts the installation method that the five-watt tilting pad is divided into two semicircles in the sliding bearing, which is simple in processing and convenient in installation, and improves the production efficiency;

(Ⅲ) The utility model not only solves the problem of difficult assembly of the sliding bearing and the shaft due to the interference of the tilting pad, but also improves the load strength of the bearing; and the overall structure is scientific and reasonable, the processing is simple, the installation and use are convenient, and the equipment is easy to use. The utility model has the advantages of long service life, significantly reduced manufacturing cost, broad market prospect and easy popularization and popularization.

The utility model is widely applicable to the supporting use of various tiltable pad sliding bearings.
