8.5 Unit Maintenance 8.6 Brake Maintenance and Inspection
•
Although it will depend on operation conditions, overhauling after approximately 20,000 hours or 3 to 5 years will
further increase lifetime. Contact the nearest authorized service station regarding overhaul.
•
Oil seals have a lifetime. During long use natural degradation and frictional wear will reduce eectiveness. Reducer
operating conditions and ambient environment will cause lifetime to widely vary. Given normal operation,
(uniform load, running 10 hours per day, normal temperature) as a guideline it is recommended to change them
every 1 to 3 years. If the sliding surfaces of oil seals or V-rings show signs of wear or corrosion, replace them with
new ones. Because sliding surfaces for oil seals are made of carbon steel, take on-going rust prevention measures
regularly not to spread rust on them by applying rustproof oil and so on, if there are exposed surfaces of steel.
•
If stop and start are frequent, mounting bolts (or nuts) and ring gear housing fastening bolts (or nuts) may come
loose. Periodically check for looseness as this is a source of miss-alignment, oil leakages, and load unbalance.
•
Avoid replenishing with a large quantity to extend the replenishment interval , as overlling could
result in overheating the bearing, grease leakage, and other problems.
•
Please maintain the unit properly. Neglecting replenishment when resuming operation, or periodic
replenishment when the unit is operating could lead to abnormal wear, bearing noise, bearing burnout,
and other problems.
•
Do not handle the unit when cables are live. Be sure to turn o the power when operating on the unit;
otherwise, electric shock may result.
•
When using for lifting, do not release the brake while a load is suspended; otherwise it could fall,
causing an accident.
•
Do not operate the machine while the brake is released by the manual brake release bolt; otherwise,
falling, going out of control, or damage to the equipment may result.
•
Before operation, turn power on and o to check brake action; otherwise falling or running out of
control could occur.
•
Do not bring water or lubricant in contact with the brake. Brake torque degradation could cause falling
or running out of control.
Given normal operation conditions, brake mechanical lifetime is quite long at 2 million times (1 million times for FB-
30, ESB-250 and ESB-250-2). These conditions include the moment of inertia for the load being no greater than the
moment of inertia for the brakemotor. However, please periodically inspect the brake gap (G).
The brake lining wears after long hours of running time, making it impossible for the brake to release. When 2 million
times is exceeded (1 million times for FB-30, ESB-250 and ESB-250-2), wear and damage to mechanical parts may
cause dropping or overdrive problems.
