Hydraulic motor is the energy transfer medium, the pure hydraulic oil compression rate is quite low, when the pressure increases by 1Mpa, the hydraulic oil is only reduced by 0.0625%, so it can be considered that the hydraulic oil is incompressible medium. When a certain amount of air is mixed, the compression ratio of the hydraulic oil is greatly increased, with a considerable elasticity coefficient, which can have a significant effect, and even there will be control failure, the work institutions produce simple harmonic movement.
The reducer has the function of matching speed and transmission torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. Reducer can be divided into general purpose reducer and special reducer, the design, manufacture and use of the two are different.
