Product Application

Speed reduction of motor used in the field of Petrochemical industry, mine, metallurgy, pottery, rubber and plastic, woodworker machinery, beverage, transportation,logistic equipment, environment protection, oil and foodstuff, medical instruments, tobacco machinery.

Application

series reducer is a kind of gear is used to reduce the motor speed and improve the output torque of the principle of speed reducer. It uses the gear and gear meshing, with advanced design and novel structure of retarding mechanism

Product features

series helical gearmotor own rational design, compact construction, smaller size than X or B series cycloidal  gearmotor at the same permitted torque.

worm gear box

The material of gears is 20CrMnTi alloy steel and the hardness can reach to HRC58°~ 62° after tempering,cementiting, quenching etc. heat treatment. All the gears are processed by accurate grinding and the precision can reach to grade 6~5.

transmission efficiency

The products have been mainly used in chemical machinery, cement agitator machinery, printing and packaging machinery,  mine and power transmission machinery,metallurgy etc.

worm gear boxes

Pay attention to the following suggestions when installing and installing the gear unit
As shown in Figure 1, the gear unit must be securely mounted on the machine to avoid vibration.
2. Check the correct rotation direction of the output shaft before assembling the reducer on the mechanical equipment.
3. When the reducer is stored for a particularly long period of time (4~6 months), if the oil seal is not immersed in the lubricating oil and exposed, remember to replace the oil seal. This is because the rubber will stick to the shaft and even lose its elasticity. . Need to fully restore its performance.

 

Main Features

worm gearbox reducer aluminium transmission gear box

1) High quality die casting aluminum alloy housing, suitable for universal mounting.

2) Heat sink design for cooling provides great surface area and higher thermal capacity than the casting iron housings.

3) 025 to 150, with power scope from 60w to 15kw

4) Larger speed ratio range. Each single frame size has 12 ratios from 5:1 to 100:1

5) Hardened worm with fine grinding has the features of higher efficiency and big output torque

6) Low noise and stably running, can adapt long term work condition in terrible environments

7) Light weight, high mechanical strength

8) Modularization combination PCRW & DRW extend the ratio of RW reducers from i=5:1 to 3200:1

The products are widely applied in electricity, coal, cement, metallurgy, harbor, agriculture, shipping, lifting, environment protection, stage, logistic, weaving, paper making, light industry, plastics and other regions.
