Definitions

• the invention relates to a rotor for a bit-in motor.
• it relates to improvements made to built-in motor rotors to facilitate the removal of the core from the shaft.
• the stator In a belt-in motor, the stator is mounted on the frame of the driven industrial machine, and the flange is mounted on the driven industrial machine. Since the iron core is generally fitted to a driven industrial machine, there are many opportunities to remove the iron core from the shaft. For this reason, it is desirable that the iron core be easily removed from the shaft. Disclosure of the purpose and invention of the invention
• the purpose of the present invention is to provide a built-in motor in which it is easy to remove the core from the shaft in order to meet this demand.
• the rotor for the built-in motor according to the invention is
• the step (11) has a hollow city (21) in which the step (11) is arranged with a force barre, and has an oil pressure supply hole (22) to arrest with the hollow part ('21).
• the sleeve (2) is configured to include an iron core (3) fitted on the sleeve (2).
• the iron core (3) is fitted to ⁇ (1) via the sleeve (2).
• an asymmetrical hollow space (21) between the ⁇ (1) and the sleeve (2) (in the direction along ⁇ (1)).
• One end face (23) is made larger than the other end face (24)), and the core (3) is removed from the shaft (1).
• hydraulic pressure or the like is applied to this hollow space C21), and it is urged in the direction using the above asymmetry (the difference in area between the end face (23) and the end face (24)). It is supposed to generate force.
• FIG. 1 is a sectional view of a built-in motor rotor according to an embodiment of the present invention in a fitted state.
• FIG. 2 is a cross-sectional view during the disassembly (1) extraction process of the rotor for the bit-in motor according to one embodiment of the Taito invention. Detailed description of the preferred implementation ⁇
• reference numeral 1 denotes ⁇ (usually the ⁇ of a driven industrial machine), which has a step 11.
• the sleeve has a hollow portion 21, and one end surface 23 is fitted on the right side (a region with a small diameter) in the figure of the step portion 11, while the other end surface 23 is fitted on the other side.
• the end face 24 is fitted on the left side (a region having a large diameter) in the figure of the stepped portion 11 and is left-right asymmetric.
• Reference numeral 22 denotes a hydraulic supply hole.
• Numeral 3 denotes an iron core, which is permanently fitted on the sleep 2. In other words, there is no need to leave this part.
• the iron core 3 is fitted into the sleep 2 and this is attached to the shaft 1 (usually the shaft of a driven industrial machine. Then, as shown in the figure, bake from the right side to the left side in the figure (after heat expansion) and press-fit. See Fig. 2
• a high-pressure hydraulic pressure of about 700 kg / ciB 2 is supplied into the hollow space 21 through the hydraulic pressure supply hole 22.
• the sleeve 2 rises while elastically deforming, and the contact pressure of the contact portion with the end faces 23 and 24 of the sleeve 2 is reduced. Since the frictional force decreases and the frictional force decreases, even if the area of the end face 23 and the end face 24 is small (for example, several ca 2 ), the sleep 2 easily disengages from the shaft 1. Can be made to It is easy to remove the iron core from the axis.
