What is the role of the spindle assembly? Spindle bearings adjust?

Replay:

The main role of the spindle is transmitted torque, plus the bearing spindle, the other parts of the rotor portion of the spindle member, mainly mechanical rotor portion different spindle member function is different, such as the turbine is to absorb the energy of steam to drive turbine power generation . Organic spindle drive the the piston external output power, the water pump spindle is driven impeller generates pressure to deliver water and other media. Spindle function and role, supported in such a manner different axis, the bearing structure is diverse, hydrodynamic bearings, roller bearings, ball bearings and other regulation varied.
