The Bushing Is Widely Used In The Equipment
- Oct 13, 2017 -

Bearing is an important part of sliding bearing.

Bearing, also known as "sliding bearing". For example, the sliding bearing made of copper is lubricated by the oil trough on the friction surface of the copper tile, which acts as a "supporting" to the ball bearing and reduces the friction of the shaft.

The bushing is widely used in the equipment of large steam turbines and generators, Bush Bearing and is lubricated with the Babbitt alloy and high-pressure oil.

In the steam turbine, the bearing is one of the important components of bearings, is the sliding bearing and the shaft touch the local, very smooth, common with bronze, antifriction alloy, Bush Bearing such as wear-resistant data is made, also known as "shaft lining", the shape of a tile-like half cylindrical surface. The main effect is: bearing the effect of the shaft neck exerted, adhere to the stability of the oil film, so that the bearing smooth task and less bearing conflict lost. It is divided into axial thrust tile and radial tile, Bush Bearing the effect of the radial tile is to support the rotor and the transformation local, the thrust tile bearing the axial position and the axial thrust effect, is the important stop component.

The general selection of welding, grinding and heat treatment of steam turbine bearings and rotors is repaired. If the bearing is the use of the plating tire after scraping, Bush Bearing grinding method to repair. Steam turbine blades are not repaired and replaced if cavitation or wear is serious.

Bearing is one of the key parts of the steam turbine, and under the smooth and cooling effect of the circulating smooth oil, the rotor of the steam turbine with high speed and heavy duty is supported.

Bearing in the task, in addition to and the shaft neck formation wear, but also with the axle neck to its load, so bearing pad data should have a small conflict coefficient, good abrasion resistance and meet high compressive strength and patience. Therefore, in the arrangement of the bearing alloy, Bush Bearing it is necessary to distribute a certain high hardness phase composition on the soft substrate. Casting Sikiba's alloy Zsnsb11cu6 fits this arrangement. Pleading, is one of the most excellent bearing alloys. Compared with all Babbitt alloy, Zsnsb11cu6 has the smallest linear expansion coefficient, the thermal conductivity ratio of PB-based alloy large $number, Bush Bearing has the highest corrosion stability and high fatigue strength, suitable for receiving special high load, HB300 around medium hardness of the hinge task, As a result, it is widely used as bearing babbitt in a steam turbine for bearings of rotor bearings.
