Fast operating condition leads to a large amount of wastes of electric energy.The viscous drive technology of liquid with stepless speed regulation characteristic meets these high-power mechanical-electricals and sets
Standby Flexible Transmission requirement, has significant energy-saving potentiality, has been widely used market.
A kind of new technology as Fluid Transmission and Control field represents, and it is fixed that hydro-viscous drive is based on friction in newton
Rule, using the viscosity of liquid, i.e. the shearing force of oil film transmits power.It is glued in drive technology in liquid, active and passive friction plate is constituted
Friction pair between be full of working fluid.During the work time, it is realized by changing spacing, that is, oil film thickness between friction pair
Adjustable, the significant advantages that have that stability is good, sensitivity is high etc. of power output.
Liquid glues drive technology and passes through nearly development in 30 years, biggish achievement is achieved in terms of theoretical research, but testing
Research aspect Shortcomings.In the existing experimental provision about the viscous transmission of liquid, complicated mechanical transmission structure leads to power tune
The decline of precision is saved, also, oil film is to reflect that liquid glues the critical mediator of transmission performance.Thus before meeting basic speed-regulating function
It puts, mechanical transmission structure should be simplified as far as possible, to achieve the purpose that improve measuring accuracy.
