6.3.8 Removing the rotor core with sleeve
The following chapter describes the removal of the rotor core with sleeve from the spindle
shaft.
Note
You cannot remove the rotor without sleeve wit
hout damage.
The rotor core is removed from the spindle shaft using the oil pressing procedure.
The supporting fixture must allow the rotor core to move.
Principle of the oil pressing procedure
Forcing oil between the spindle shaft and the rotor core releases the step press fit.
The oil pressing procedure causes a high level of mechanical stress in the components.
If the pressure is sufficient, the spindle shaft will slide off the rotor core.
The necessary section for the relative movement is specified by the construction of the
stepped press fit. The section is specified by dimension A in the "Rotor core removal" figure.
Precondition for removal using the oil pressing procedure
Observe the following safety measures during removal.
● Check the pump and accessories for functional safety.
● Operate the pump only with manometer.
● Do not make any changes to the device and its safety equipment.
● Observe the notes contained in the oil press pump operating instructions.
● Wear a face protective mask and closed work clothes.
● Vent the hydraulic system.
The oil pressure is built up manually.
● Do not exceed the maximum permissible oil pressure (see "Maximum permissible oil
pressure" table)
