Introduction

To make the tilting pad according to GB/T 23892.1-2009 calculated thrust bearing to achieve sufficient operational reliability, calculated For high pressure ratio and/or extreme high speed operating condition, it is necessary to consider the heat, the elastic deformation, hydrodynamic and/or turbulence effects were More accurate calculation. These values \u200b\u200bcharacterize the allowable operating limits depend on the size and geometry processing technology bearing tribological system. These are some of the experiences value. Even will be some impact in other areas, it is still possible to meet the operational reliability (see GB/T 23892.1-2009 Chapter 4).

3 to avoid the wear and tear damage to the allowable value

Symbol definition and calculation example see GB/T 23892.1-2009. Lubrication. Lubricant should be clean and free of impurities because the impurities will increase wear and tear, strain and local overheating, which would weaken the sliding bearings Normal function. When necessary, the lubricant should be filtered. Formula (1). The formula takes into account the increase in the overall size of the bearing, increase manufacturing tolerances. However, in this series of standards, processing methods and the actual status of the machine on a large machining tolerances, therefore, according to the formula Shaft flange error processing or thrust collar and exceed the allowable tolerances, will lead the thrust pad to fail. In addition, the machine start-up and How long in mixed lubrication work is also very important when downtime. For higher rotational speed, it should increase the minimum allowable normal operation with the film thickness, so that shutdown will not arrive too quickly mixed Lubrication.
