Worm Gearbox Reducer for Construction Hoist Or Passenger Hoist

Features

1. The worm gearbox reducers for construction hoist or passenger hoist have the following features because of using plane enveloping worm gear as compared with other kinds of worm transmissions: larger loading capacity and compact dimension and higher efficiency and smoother and quieter functioning longer service life.

2. In addition, the housings of these series worm gearbox reducers are made of high-strength aluminum alloy. So the reducers make the features of higher strength and lighter weight.

3. 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.

Installation

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

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

3. The 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 over-loose mate.

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

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

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

Usage

1. Before using, please check carefully whether the worm gearbox reducer module, 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 proper category and brand lubricant. And then screw on the vent-plug, unlock the small cone-plug of vent-plug. Only after doing these, reducer is already for starting up running. The proper brand and adequate lubricant oil is required, replacing oil in time conforming to the request of product manual is also necessary, especially after using first 100hours, it is required refilling new oil.

3. When abnormal circumstances occur, please stop and check the worm and gearbox reducer per solutions and reasons for faults of reducer(allowable highest oil temperature is 95, under this temperature limit, if oil temperature no more goes up, please let reducer continue running).

Characteristics

1. Worm and gear are circle-arc tooth, large carrying capacity, high transmission efficiency
2. Using high quality seals, taking airtight tests before leaving the factory, good seals.
3. Each set has a tooth test to ensure that the product operates smoothly with low noise.
4. Worm gear has a high accurate machining, take the quality inspection through the Germany Klingelnberg detector, and has a long service life.
