Analysis of Bearing Loads for Scroll Compressor Considering Phase-Angled Counterweights
In order to improve the dynamic characteristics of scroll compressor, according to the crankshaft bearing characteristics of scroll compressor, based on the forces and moment equilibrium equations of the crankshaft and compressor frame body, used the frame body forces and crankshaft bearing loads as a variable, analyzed the frame body forces in the best of conditions by changing the counterweights installation angle to control the crankshaft bearing design formulas, thus obtained counterweights quality and phase angle and other parameters, ensured the service life of the bearing, and obtained effective control of the crankshaft bearing load and frame body force, improve the operation reliability of scroll compressor, prolonging the service life. This paper puts forward a set of formulas, which are derived based on analysis of the loads at crankshaft of scroll compressor. The formulas can be used to determine the parameters of installation angle of the counterweight and the forces of loads at crankshaft for scroll compressor.
