Radial load on output shaft not accounted for in the calculation above. Lubrication. As Hyponic Drives are sealed with long-life grease, replenishment is practically unnecessary, but overhaul in approximately 0,000 hours or 3-5 years of operation will provide longer service life.. The durability of oil seals is subject to operating conditions. It may be required to change them in less than 0,000 hours or three years of operation under severe conditions.. Overhaul of gear motors must be performed at our specified sites with professional knowledge and technique. data C

Refer to the table below for sizes of the bolts.. Leave some allowance in the section of torque arm whirl stop so that excessive force will not be applied between Hyponic Drive and the driven shaft. Don't secure the torque arm with the whirl stop bolt. Or it may damage the whirl stop bolt, the torque arm, Hyponic Drive, or the machine. In case of frequent start/stop operations, or repeated normal/reverse operations, use a rubber bush between the torque arm and mounting bolt or spacer to absorb the shock.
