Abstract
With the rapid development of productivity and the increasing promotion of modernization, the consumption of energy is being greatly increased, which may lead to energy crisis or the rising of the price of energy. As a result, the target of energy saving has been a more and more emergent task.
As a new type of power transmission device utilizing the shear of oil of film between two sets of discs. It is widely used for speed regulation and energy saving in large fans and pumps.
This thesis introduce the research and experimental system in speed regulating clutch liquid viscosity ,which face to the demand of the film hydro-viscous drive clutch, it will set up a platform to do the theory research of film cut drive.
Chapter 1 mainly introduces the background and significance of the research theme, including the performance of the hydro-viscous and the advantage of the use of hydro-viscous. It also introduce of the development of the hydro-viscous at home and abroad.
Chapter 2 mainly introduces the work elements, configuration and the work characteristic of the speeding wet clutch;
Chapter 3 is the mainly part of this project, it introduce the design of the experimental system and give a outline first , then explain the design process in three aspects: the hydraulic par
Key words: Energy saving; Speed Regulating Clutch Using Viscosity; experimental system; hydraulic pressure system;design
