Notice

a. It is recommended to utilize the viscosity VG320 synthetic worm gear oil (or synthetic gear oil) for lubrication. Once the environment temperature is higher than 30°C, it is recommended to utilize the viscosity VG460 synthetic worm gear oil (or synthetic gear oil) for lubrication. And allowed maximum working oil temperature is 100°C.

 

b. Notice of installation of cheap gearbox prices for lifting machinery, worm gearbox :

①The base-plate must be plane and stoutness and the base-plate must be screwed down and shockproof.

②The connecting shaft of prime mover, reducer and operation device must be coaxial installation.

③The diameter tolerance zone of input and output shaft is H6, the holes of fittings( such as couplings, belt-pully, sprocket wheel and so on) must properly mate the shaft, which prevents bearing from breakage because of an over-loose mate.

④Drivers such as sprocket wheels and gear must be fitted close to bearings in order to reduce the bending stress of hanging shaft.

⑤ While assembling the motor of WPD reducer, it is necessary that the proper amount of butter applies to the warm shaft input hole and keyway, avoiding assembling too tightly and rusting after using it for a long time.

⑥When ordering or using all kinds of WPD type, if the motor weight is bigger than the common, a supporting set is required.

 

c. Notice of usage of cheap gearbox prices for lifting machinery, worm gearbox :

1. Before using, please check carefully whether the reducer model, distance, ratio, input connecting method, output shaft structure, input and output shaft direction and revolving direction accord with required.
2. According to the requirement of selecting lubricant oil in the product manual. Please fill the proper category and brand lubricant. And then screw on the vent-plug, unlock the small cone-plug of vent-plug. Only after doing these, the reducer is already for starting up running. The proper brand and adequate lubricant oil are required, replacing oil in time conforming to the request of a product manual is also necessary, especially after using the first 100hours, it is required refilling new oil.
