Hydruviscous varliable speed clutch1 Subject content and applicable scope
This standard specifies the classification, technical requirements, test methods and inspection rules of hydroviscous variable speed clutch. GB/T 15096—94
This standard applies to hydroviscous variable speed clutch (hereinafter referred to as clutch) matched with speed-adjusting working machine. 2 Reference standards

GB1570 Tapered shaft
3 Terms
3.1 Hydraulic drive
A transmission mode that uses viscous liquid as the working medium and relies on the liquid precision between the master and driven friction plates to transmit power to adjust the speed and torque.
3.2 Hydroviscous variable speed clutch A transmission device that follows the hydroviscous transmission method, adjusts the output speed by changing the oil film thickness between the master and driven friction plates, and also has clutch function.
3.3 Pressing force
The force that makes the master and slave friction plates engage. Usually, this force is applied by the pressure piston through the pressure plate. 3.4 Synchronous working coupling Under a sufficiently large pressure, the master and slave friction plates engage and transmit power by solid friction. Working conditions when the output and input speeds are the same
3.5 Separating working condition When the pressure is small enough (the repulsive force is close to zero), the master and slave friction plates are separated. 3.6 Variable speed working condition When the clamping force is changed, the master and slave friction plates change, making the output speed lower than the input speed. 3.7 Speed ​​ratio
The ratio of the output speed to the input speed.
3.8 Range of speed regulation The speed ratio range within which the output speed can be continuously adjusted and operated at a constant speed. 3.9 Speed ​​fluctuation ratio. Under the operating condition of constant load, the absolute value of the difference between the recorded output speed nm (or minimum output speed m) measured within a certain period of time and the average speed n within the period of time, divided by the average speed m, that is: 6 _ Im (or nm) = m = 1 100%
