Flexible Motor Connection
The modular design of motor connection plate is
suitable for any brand servomotor and stepmotor. The input-end and the motor are coupled through a collet locking meshanism. It has passed dynamical balance analysis to assure concentricity and balance on the connection and no backlash for power transmission while running at high speed.
High Accuracy
Repetitive Positioning Accuracy ±10 sec Torsional Backlash ≦ 1 arcmin Lost Motion 2 arcmin
Bearing
Utilizing high-precision crossroller bearings with a small size and compact structure, capable of simultaneously handling radial and axial loads. In applications with lower axial loads, ball bearings can also be chosen.
Direct Mounting of Workpiece
The rotating table allows for direct mounting of workpiece for added convenience in workpiece loading.
Hollow Structure Design
Make it convenient for electric wiring or piping work.
Helical Gear Design
The speed reduction mechanism employs helical gears, which provides two times meshing rate of teeth when comparing with regular spur gears. ln addition, it also Specification extremely smooth running, low noise, high torque output and low backlash.
High Precision Gear Machining
The housing of reducer is made by aluminum alloy, and precision machining by CNC machine. Precision teeth grinding assures gear accuracy reaches DIN6 class.
