POWER GENERATING DEVICE USING MAGNETISME

摘要

To provide an axis gear compressing apparatus to insert and connect an axis gear into the axis of small motor, such as feeding motor applicable for the pick-up driving of mini-disk player. The axis gear compressing apparatus of small motor consists of axis gear fixing part(14), cylindric housing(22), motor fixing part(28), piston(32), air hose(34) and motor axis supporting part(40). The axis gear fixing part is to fix a axis gear(90) to be connected to a motor axis(62). The cylindric housing(22) is connected to the bottom of inner side of tool chuck(18) by handle(16) operation and is fixed by connecting pin(20). The motor fixing part(28) is to install motor(26) which is inserted to the bottom of housing inside and is fixed by fixing screw(24). The piston, inserted between the top of inner side of the housing and the top of motor fixing part, is always operated upwards by spring(30) and supports the rear part of the installed motor. The air hose puts air pressure to a space between the top surface of the piston(32) and the top surface of the housing(22) inside. The motor axis supporting part is to support a motor axis(62). Thereby, it is possible to provide a high trust with an uniform compressing condition of axis gear due to the compression using air pressure.
