The CAVEX® gearing that was developed by Flender gives unequalled durability and reliability in the worm gearbox section.
We are continuing on this long history of quality and are still producing the complete range of Flender CAVEX® gearboxes.
CAVEX worm gearboxes are quite unlike any other. We have been proving this with our patented CAVEX® gearing system in almost all industrial sectors across the world for more than 60 years. Our unique gearing geometry is far superior to standard worm gearboxes.
Cavex tooth type worm does surface contact while involute tooth type worm does line contract with the wheel.
The contact area increases evenly to transmit 3~5 times more load than involute tooth type worm. The strength of teeth increases more than involute tooth type.
The lubricant is not pushed outside by surface contact; the lubricant is kept evenly between worm and worm wheel teeth to form oil film 2~3 times faster than involute tooth type; and the thickness of the oil film is 3~4 times more. In addition, the thicker oil film increases the life of the worm and worm wheel remarkably.
The efficiency is 20~30% higher than the line contact worm of involute tooth type.

CAVEX® worm gearboxes feature a low noise, shock absorbing torque transmission.
The tooth flanks of the worm shaft are hardened and sanded and a high quality bronze is used for the worm wheel which leads to an excellent finish that withstands wear and tear and gives a long service life.
Applications : • steel industry • Elevator drives • Escalators • Solar technology • Mixers
Grey cast iron casing
Centre distance 63mm to 630mm
Helical or worm pre-stage for transmissions from i = 5 (single stage ) to i = 5000 (multi-stage)
Special models and combinations for custom-made applications
Foot, flange or torque arm mounting
Various mounting positions are possible
We also supply our gearboxes in combination with a three phase asynchronous motor in a range from 0.09 to 800.
Multiple speed motors, braking motors and explosion-proof motors are also part of our range.
The motors can be supplied with single or double brakes, incremental encoders and handwheels according to our customers’ requests.
We can also supply complete units with frequency converters.
CAVEX® worm wheel sets consist of a hardened and sanded worm and a worm wheel made of high-quality, durable bronze.
Worm wheel sets feature shock-resistant, low vibration and low noise gearing and achieve high levels of transmission in each individual stage.
A self-locking feature when the set is stationary is possible. We produce worm wheel sets from standardised modules or to our customers' specifications. Modern high-precision gearing machines are used and along with constant improvements in technology, we can achieve highly sophisticated individual solutions.
