Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, in particular to a rotor pressure bearing device. Background Art

[0002] The bearing press is a widely used motor bearing installation mechanism. Traditional bearing presses mainly use a fixed-axis bearing installation mechanism to press the rotor and bearing. First, the shaft is fixed on the fixture, and then the outer ring of the bearing is clamped by the clamping mechanism. Finally, the bearing is forced onto the shaft through the action of hydraulic pressure to fix the shaft and bearing.

[0003] However, the existing rotor bearing press-fitting devices generally have the following technical problems during press-fitting:

[0004] When the bearing is formally inserted into one end of the rotor, the rotor needs to be fixed and positioned first, and the outer periphery of the rotor needs to be fixed with the help of a clamp. For example, a clamp is pressed down by an oil cylinder or a hydraulic cylinder on the top of the rotor, and the clamp abuts against the side of the rotor. The greater the downward pressure, the greater the friction formed on the outside of the rotor, and the more firmly the rotor is fixed. However, with existing devices, the greater the pressure applied to the top of the rotor, the greater the load-bearing pressure and shear resistance of the support device for the rotor below, resulting in poor stability of the support structure for the rotor below, which may lead to inaccurate rotor positioning and cause certain damage to the precision bearing.
