We produce various designs of worm gear sets according to customer drawings with all common standard profiles. The CAVEX® gear box use the advanced and reliable high-power transmission worm gear, won the good reputation by OEM equipment manufacturers. 

In case of tool machines with increased demands towards accuracy and rigidity the DUPLEX wheel set is usually the set of choice for many applications. In this wheel set the worm is designed with an adjustable incline, thus allowing an exact setting of the wheel set. This provides the ground for high precision production. The geometry profile of the CAVEX®-wheel set is decisive for the long standing time and the high load capacity of the wheel sets. Due to the hollow flank profile, the material characteristics of the high quality bronze of the wheel and the case hardened worm can be fully exploited because flank pressures are significantly reduced and the lubrication of the teething is clearly improved under all operating.
Meanwhile, because the worm tooth root width increases, the wheel set can be withstand the more impact stress.

CAVEX® wheel sets are designed for the highest loads by the most modern calculation tools.  The high reliability of CAVEX® gear wheel sets is most important under rough operating conditions. Each wheel set is monitored by stringent quality control, and special emphasis on meshing test. What we pursue is that ‘Quality first, Customer confidence’.
The manufacturing range of CAVEX® gear wheel is:
· Axle distance 40 – 1,400 mm
· Gear ratios 1 – 180
· Module 1 – 40
· Number of teeth on a worm 1 – 12
· High accuracy
· Special requirements possible
