We Create Solution Spaces

What is possible? What is sensible? And is the possible solution always sensible - or are there any other, better, more efficient solutions for you? These ideas guide us at ZHAWOEI when it comes to developing custom-fit planetary gears together with our customers.

As an experienced development partner, we at ZHAWOEI are always excited to find new solutions for the world of tomorrow. Our wide range of configuration options not only offers you more opportunities but also greater safety and efficiency. What we generate from this is your highly individual solution space - from prototype to serial production.

Applications for innovative markets

Gearbox (also called gearhead)

A gearhead mechanism capable of increasing torque by reducing the motor speed. An approximate value can be calculated using the following equation. The reduction ratio has been established for each model. Please see the pages of products.

speed of gear motor

Gearbox Structure

Gearboxes are roughly divided into two types of structures. Planetary Gearhead

Gear Efficiency

Gearheads have mechanical loss (gear meshing, bearing friction, etc.). Generally, for each meshing of one stage, an efficiency of 81% for planetary gears and 90% for spur gears is used in calculation. The gear efficiency, however, varies largely depending on such factors as motor torque and speed therefore is presented as a reference value. When used at a lower torque, the efficiency will drop significantly.

An example of calcuation of efficiency

  • Spur gear 3-stage meshing
Efficiency (η) =0.9 x 0.9 x 0.9=0.73 (73%)
  • Planetary gear 2-stage meshing
Efficiency (η) =0.81 x 0.81=0.73 (66%)

Backlash

The amount of gearheads backlash depends on a play required for smooth meshing and a play between the shaft and the bearing. Note, however, it increases under load due to elastic deformation.
