Claims

[Scope of utility model registration request]

In an apparatus in which a motor rotates the upper part of a main shaft which is installed hanging down with a bearing provided on the shaft head of the apparatus main body via a transmission means such as a belt, and a processing tool is attached to the lower end of the main shaft protruding from the shaft head, the above-mentioned The tool mounting provided at the lower end of the main shaft has a side bearing mechanism, a thrust bearing plate fixed to the main shaft extending to the inside of the shaft head, and a surface fixed to the shaft head and sliding on the lower surface of the thrust bearing plate. a bearing plate; a radial bearing fixed to the thrust bearing plate with the same sliding surface as the bearing plate and with its center aligned with the main shaft; and the radial bearing;
It is characterized by having a sliding surface with a bearing plate and a thrust bearing plate fixed to the radial bearing, and configured so that a machining tool can be surface-mounted on the thrust bearing plate at the lowermost end. Bearing structure of surface grinder.
