BEARINGS PLAIN
Plain bearings are an important type of rotation bearings, which are often used in structures operating in difficult conditions, namely: under high vibration and shock loads; low and especially high speeds; increased requirements for stability and accuracy of the position of the shafts; work in water and aggressive environments; lack of lubrication or without it at all, etc. t the optimal design of bearing units.
Plain bearing types
APM Plain allows you to calculate bearings of the following types:
- radial, operating in the mode of liquid friction;
- radial, operating in the semi-fluid friction mode;
- thrust bearings (thrust bearings) operating in the liquid friction mode.

Features of APM Plain
Using the APM Plain module, you can find:
- distribution of radial and axial clearances;
- optimal gap value;
- parameters of the lubrication system (lubricating film thickness, maximum and average oil temperature, oil consumption);
- actual coefficient of friction and friction losses;
- construction parameters.

Criteria and calculation methods
The criterion for calculating fluid friction bearings is the condition under which the thickness of the gap between the surfaces in relative motion is not less than a certain specified allowable value.
For semi-fluid friction bearings, a similar criterion is formulated as a requirement in relation to the operating temperature of the bearing: it must be less than allowed for a given type of oil.
Liquid friction bearings are calculated by solving the Reynolds equation and the equilibrium equation. In this case, the fluid flow in the gap is considered to be laminar.
The method for calculating a bearing operating under conditions of semi-fluid friction is based on the study of the process of heat release during friction and the solution of heat transfer equations.
