Dynamic Characteristics Of Anti-rotation Mechanism Of The Scroll Compressor

Scroll compressor as a new type displacement compressor,possessing characteristics of high efficiencysmall bulk, light weight, low noise, simple structure and working smoothly etc, is widely used in refrigeration and air-conditioning units. The compressed gas tangential force of the scroll compressor,have made two scrolls trend and the anti-rotation relative to the trend. Moment of resistance to rotary torque or the original motive of the input torque to overcome, the built-in anti- rota- tion overcome torque and rotation from mechanism balance. The studay on the dynamic characteristics of the anti-rotation mechanism of Scroll Compressor,guarantee the normal opera tion of the scroll compressor and parameter optimization design is of great practical significance,which is this paper focused on.Scroll Compressor thermal characteristics is the basis for its work, and impact of the structure of the important factors. In this paper, initially on the thermodynamic characteristics of the scroll compressor, and based on the first law of the modyn-amics and the law of conservation of the quality of objects, mainly on the scroll compressor compression chamber thermal state of a preliminary discussion. The establishment of a scroll compressor heat transfer model,Considered the suction, compressed, leakage, exhaust, and other factors on the process of the compressor.The structure of several common anti-rotation mechanism of Scroll Compressor: Oldham coupling anti-rotation mechanism and ball-bearing anti-rotation mechanism and small wrist crank anti-rotation mechanism.This paper analyzed these three anti-rotation of the structure, Campaign model, Stress model, orbiting scroll dynamic model. The mechanical model of spindle orb-iter, as well as the calculation of overturning moment and discover the small wrist crank further on the movement and force balance equation based on previous studies, Analysis the anti-rotation mechanism of different number of the dynamic characteristics, Research on the role and power of the deformation, as well as a number of the deformation.
