Problems solved by technology

The wedge-shaped pressure oil film between the bearings cannot be established normally, and the spindle cannot run smoothly
As a result, large vibration and noise of the whole unit are caused, and the power loss of the machine is greatly increased, so that the working life of the unit is reduced.
Therefore, the currently used tilting pad dynamic pressure sliding bearings have very high requirements for installation accuracy. During installation, the size of the gap and the fit and position of each bearing pad must be strictly controlled, which brings great challenges to the installation of the bearing. the inconvenience

Embodiment Construction

[0014] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The device structure of the integral multi-oil wedge tilting pad dynamic pressure sliding bearing of the present invention is as follows: figure 1 As shown, the bearing seat 2 and the bearing bush 3 are integrated, the bearing seat 2 and the bearing bush 3 in the center are an integral structure processed by wire cutting technology, the bearing bush 3 is connected with the bearing seat 2 through the protrusion in the middle of the outer side, and the bearing bush 3. There is a gap 6 between the outer surface of both sides of the protrusion and the bearing seat 2. Wire cutting technology is used during processing. According to the design requirements, the gap 6 between the bearing seat and the bearing bush is precisely processed. The inner surface of the bearing bush 3 is covered with Babbitt alloy 5. The bearing seat 2 is hot-fitted int...

Abstract

This invention relates to an integral multi-oil wedge inclined bush dynamic pressure sliding bearing, which contains bearing seat and several bearing bushes, said bearing seat and central bush are integrated structure worked by wire cutting, the inner surface of bush made from Babbitt alloy to increase wearing resistance, bearing seat using interference fit to mounting in bearing flange with oil filling hole. Said invention insures the normal formation of wedge shape pressure oil film, reduces vibration and noise of whole machine set, increases rigidity of rotation pair, raises anti vibration ability and prolongs service of bearing and bearing bush.

Description

technical field [0001] The invention relates to a sliding bearing, in particular to an integral multi-oil wedge tilting pad dynamic pressure sliding bearing for fluid machinery, which belongs to the technical field of bearings of mechanical products. Background technique [0002] The multi-oil wedge tilting pad dynamic pressure sliding bearing is a high-precision sliding bearing. It has multiple independent and evenly distributed convergent oil wedge surfaces. When the main shaft rotates at high speed, the oil wedge surface still maintains a wedge-shaped gap, so Regardless of whether the main shaft is loaded or not, each independent oil wedge can form a uniform bearing oil film and keep the rotating main shaft in a state of non-eccentric rotation. Fluid dynamic pressure sliding bearings have outstanding advantages such as good rigidity, large carrying capacity, low power consumption, good impact resistance, good vibration resistance, and high running precision. In impeller ...
