Title:
ROTARY BODY DRIVING APPARATUS
Document Type and Number:
Japanese Patent JPS58196354
Kind Code:
A
Abstract:
PURPOSE:To permit a rotary body to be provided with a rotational force proportional to a driving torque by installing a piston cylinder unit which press a frictional driving body onto the rotary body by the pressure substantially proportional to the driving torque generated in a hydraulic motor. CONSTITUTION:A hydraulic motor 21 is driven by driving a hydraulic pump 23, and a roller 16 is revolved. As the roller 16 and a frictional flange 7 are frictionally engaged, a rotary body R revolves. When the pressure of the pressurized oil supplied to the hydraulic motor 21 increases, a piston cylinder unit 17 pulls a casing C leftward as shown in the drawing, and the roller 16 and the frictional flange 15 are pushed by the force proportional to the hydraulic pressure. Therefore, as the hydraulic pressure increases, the frictional force on the engagement surface increases, and a frictional force proportional to the driving torque can be obtained.
