APM Plain

Plain bearing is an important type of the rotation supports that is frequently used in complex environments under high vibration and shocks, very low and very high rotational speed, high demands on the shaft stability and accuracy, for the units working in the water and in the aggressive environments, in the absence or lack of the lubrication, etc. The reliability of the bearings determines the reliability of the equipment they are installed in. APM Plain performs a complex analysis of the plain bearings. When using the system you can determine the basic parameters of the bearing and select the optimum construction of the bearing unit.

Entering the initial data for calculation

Plain bearing types

With the APM Plain the following types of the bearings can be calculated:

  • radial bearings that work in fluid lubrication mode
  • radial bearings that work in semifluid lubrication mode
  • thrust bearings that work in fluid lubrication mode

АPМ Plain possibilities

    Using APM Plain one can calculate:

  • radial and axial clearance distribution
  • optimum clearance value
  • lubrication system parameters (oil film thickness, maximum and average oil temperature, oil consumption)
  • true friction coefficient and loss of power
  • optimum dimensions of the bearing elements

 APM Plain calculation results

Calculation criteria and methods

Calculation criterion for radial bearings that work in the fluid lubrication mode is the condition of minimum allowed clearance between bearing contact surfaces.

Calculation criterion for radial bearings that work in the semifluid lubrication mode is requirement for bearing working temperature to be less than the maximum allowed one for given oil. 

Oil parameters

Calculation of radial bearings that work in the fluid lubrication mode is performed by Reynold's equation solution. So the fluid flow is considered to be laminar.

Calculation method of radial bearings that work in the semifluid lubrication mode is based on analysis of heat release by friction and solution heat transfer equations.
