FAQ About worm planetary drives

Worm gearbox has the added advantage of irreversible mechanism

Worm drive has less efficiency as compared to other drives

We offer planetary gearbox with foot, flange or shaft type of mounting

Prime mover can be electric motor, hydraulic motor or engine.

We provide planetary gearbox from 0.18 kW to 1000 kW

Normally we provide oil lubrication but in some cases depending upon applications we provide greece lubrication

Efficiency of planetary gearbox is 96 to 97% for 1st stage and it varies depending upon surface finish

Thermal rating relates to thermal capacity of gearbox.Thermal rating is continous power transmitted by a gearbox with splash lubrication and maximum oil temperature of 90 degree celcius at ambient temp of 25 degree celciusand input speed 1500 rpm.

Planetary Gearbox can be upto 6 or 8 stages having reduction ratio from 3 to 1 Million

Oil grade depends upon the speed and temperature. For low speed high viscosity oil is required whereas for high speeds low viscosity oil is required. Normally, ISO VG 220/320 is commonly used

For appropriate selection of planetary/bevel/worm gearbox following input data is required 1.Type,power and input speed of prime mover 2. Application of product where it is going to be used along with its operating hours and duty cycle. 3. Output speed or Gear ratio

Actual Service factor for selected model is ratio of rated torque(max torque transmitting capacity)
to generated torque(TORQUE GENRATECD DUE TOPRIMEMOVR.It has been introduced to take into account the characteristics and working hours per day of the driven machine. It depends upon application of product along with its operating hours and duty cycle

95 degree celcius (it may vary depending upon type of lubricant)

Bearings are selected as per size and application of gearbox. In normal gearboxes ball bearings are used. Where the thrust and radial loads are high Taper roller or spherical roller bearings are used.

Double Lip oil seals are used in this product
