Basic principle |
||
1. | Power of the traction drive is transmitted by the rolling contact mechanism via oil film of traction grease characterized by high viscosity at high pressures. | ||
2. | Contact pressure P is created at each contact surface on planetary rollers, a sun roller and a stationary housing, which are assembled with elastic deformation. By this pressure, the oil films changes to high viscosity one (only when contact pressure P is imposed) so that the power can be transmitted at the roller contact area. |
||
3. | The ranction force T is formulated by Equation (1). T = µP……… (1) where, µ:Traction coefficient, P:Contact pressure |
||
4. | This unit is a speed increasing device which the revolution of the planetary roller is used for input side and the rotation of the sun roller is output side. The speed increasing ratio is formulated by Equation (2). N = 1 + D/d………(2) |

Positioning Block (Optional for use on M/C) The positioning block and pin mechanism supplies coolant to the tool. |
Orientation Ring The fitting positon of a positioning block differs among machining centers. The position can be adjusted by rotating the orientation ring whithin 360°. |
||||||||||||
Positioning Pin "One-touch" adjustment, with in a height range of 40mm. |
Coolant Nozzle The angle adjustment of the coolant nozzle can be made easily by hand. The sprya angle of the coolant is adusted to match the inserted cutter length. |
||||||||||||
Nut The balance adjustment is already made in the factory. |
Collet Only a under super precision collet, runout within 3 microns, should be used.Various sizes can be supplied by mm unit.Please order sizes to match the shanks of tools to be used. |
