Naturally, equipment specifications and performance are designed assuming that the expected motion is attained, but if there are factors such as backlash, insufficient rigidity or control instability in the motion control section, then output motion will deviate...

Naturally, these stationary characteristics are important, but in reality, accuracy and stability during movement have a large impact In motion equipment with backlash or inferior response, motion does not proceed in accordance with control commands due to deteriora- tion of...

ttti RollerDrive specifications It^Dl^ Specification sheet ^7 IJ Xj^O/Htt^il Grease lubrication type The RA series has two different lubrication options. Select the lubrication type according to your actual operating conditions. Grease lubrication is the standard lubrication method, while oil lubrication should be selected for high-speed operation. To check that the service life of the RollerDrive will be satisfactory, please compare the specifications for each lubrication type. On the dynamic rated output torque curve (see page 4), when the point (Torque and Speed) is below the curve, an...

KIAHSM!/^ Dynamic rated output torque The dynamic rated output torque is value of load torque for which an expected service life of 12,000 hours or greater is ensured. The dynamic rated output torque is dependent on the average output rotation speed.

This indicates the percent of input power which is transmitted to the output. The RollerDrive motion mechanism has high efficiency because it employs rolling contact. Efficiency varies depending on conditions such as load torque, rotation speed and temperature.

Torsional rigidity is the ease with which the shaft twists in response to output shaft torque, and is expressed as the slope of the line connecting the two points for 50% and 100% rated torque on the hysteresis curve (=> p.25). The higher the torsional rigidity, the smaller the deformation in response to torque, and the higher the natural frequency.
