Use  of Series H Right Angle Gearboxes  

a. The rotation direction of the prime mover must correspong with the stipulation, otherwise the gears will be not turned and the machine can be caused owing to the stopping effect of the non-reverse coupling. If the prime mover is a electromotor after shutdown the rotation direction must be inspected whether to be changed before starting next time.   

b. The output power of the prime mover shall be less than or equal to the corresponding power value. Diverse type of the gearbox allow speed of vertical shaft to be diverse.   

c. In running the downward tenside force that the working machine acts on the vertical shaft of gearbox isn’t below the minimum axial thrust in the list 1, otherwise an axial force of the gearbox and appending an axial force by the upper bearing will make the inner race of bearing separating upward by the vertical shaft carrying, so that affects normal motion of the bearings and the gear pair even causes the gears, bearings and shafts, etc. parts to be destruction. The downward tenside force neither can be greater than the maximum axial thrust in the list 1, otherwise the working life of the upper bearings will be reduced.   

 d. For the first time have given gearbox to have added oil or having replaced oil, after working one number of runs should take apart the plug screw of the filler, and inspect the oil level of the gearbox before starting at second number of runs. When the oil level is below the thread bottom of the filler, should supplement oiling. In the context of the gearbox does not leak afterwards the oil level have been inspected once per week. To discover leaking you must find the cause and remove the fault promply.   

e. During gearbox running you must survey on time the case that the lubricating oil are sprayed. If insrfficient quantity of spraying oil, ought to be a shutdown inspection when make that spraying oil are restored to normal only can go on use. During running yet note vibration, sound and temperature of the gearbox whether to be normal.
