VIBRATION PREVENTION STRUCTURE OF HAND GRINDER

摘要

A vibration prevention structure of a hand grinder is provided to perform a precision process and reduce fatigue of a worker by performing a grinding work stably. A vibration prevention structure of a hand grinder includes a cylinder(10), a rotor(20), a rear plate(40), a rotation transfer unit(50), and a rotation shaft(60). High pressure air from an air supply unit(41) is supplied to the inside of the cylinder through the air supply unit of the rear plate. The air is supplied to the rotor on which a blade is installed on an outer circumference plane at a regular interval. A rotation force of the rotated rotor rotates the rotation shaft of which a grind wheel(61) is installed on a front part. The grind wheel grinds an object. The rotor is installed on the cylinder of which lateral inner diameter is larger than a longitudinal inner diameter. An air supply hole and an air exhaust hole are formed on the cylinder of an ecliptic shape. The rotor having the same diameter with the longitudinal inner diameter is installed on the inside of the cylinder.
