Document Type and Number:
WIPO Patent Application WO/2015/064204
Kind Code:
A1
Abstract:
Provided is a main spindle mechanism for a machine tool such that even in the case of a small-diameter spindle, it is possible to increase the torque transmitted to a large cutter and it is possible to prevent contact to and collisions with the workpiece. The main spindle mechanism, which is provided to a machine tool that cuts a workpiece by means of a cutter, is characterized by having: a spindle that transmits torque from the drive power source of the machine tool and is formed with external teeth at the outer periphery of the tip thereof; a large cutter arbor provided with a shaft for attaching the large cutter and a base at which external teeth are formed having the same diameter as the outer teeth of the spindle; and a gear-coupling-shaped sleeve that is provided in a manner so as to cover the base of the large cutter arbor and the tip of the spindle, and at which are formed inner teeth that mesh with both the outer teeth of the spindle and the outer teeth of the large cutter arbor.
