Planetary gearbox

Planetary gearbox is a gear system consisting of one or more outer gears, or planet gears, revolving about a central, or sun gear. Typically, the planet gears are mounted on a movable arm or carrier which itself may rotate relative to the sun gear.


We are the proud manufacturers of Planetary gearbox and expert in the field of Gear box Selection

                                                            

Features of Planetary gearbox:

• A Planetary design of VGM that provides upto 3 times the torque capacity than that of conventional spur gearhead
• The torque transmitted by the sun gear is equally distributed through the planet gear, each planet gear carries one third of the torque and the resultant forces cancel each other to yield a resultant load equal to zero hence longer life
• can be mounted directly with any servomotors
• is easy for installation and compatible with 50W-4000W well-known servomotors
• integral gear ratio from 3 to 1000
• standard gear reducers with tiny backlash within 10 minutes and special gear reducers with 3 arc minute
• Many types of planetary gearbox from professional wholesale planetary gearbox supplier.We are engaged in planetary gearbox on sale for many years.
• less noise (low decibel)
• compact and lighter weight from 1.5 kg to 24 kg
• total enclosed design, lubrication refilling is not needed. The gearhead comes with factory installed grease that is circulated continuously during the operation and lubrication refilling is not required.
• Planetary Gearboxes - Wide Selection of Planetary Gearbox. Low online prices for high quality Planetary Gearboxes in stock with customer support.
• high rating torque( 3to 45 kgf-m) and low inertia (0.306 to 35 kgcm2)
• high power to weight ratio,
• higher power to size ratio,
• higher torsional stiffness, higher wear resistance
• special design gear heads can be supplied on request

Torque limiter

Torque limiter is an automatic device that protects mechanical equipment. Torque limiter may limit the torque by slipping (as in a friction plate slip-clutch), or uncouple the load entirely (as in a shear pin). The action of a torque limiter is especially useful to limit any damage due to crash stops and jams.
Torque limiters may be packaged as a shaft coupling or as a hub for sprocket or sheave. A torque limiting device is also known as an overload clutch..



We Manufacture the best Torque limiter

We are Experts in Manufacturing and supllying torque converter and the limit torque

torque converter

Features of torque limiter are:

A torque limiter is an automatic device that protects mechanical equipment, or its work, from damage by mechanical overload.

• Safety couplings with metal bellows to connect 2 shafts for compensation of misalignment (conical Hub).
