Worm Gearbox Options

The worm gear reducer consists of a worm and worm wheel enclosed in a square housing. Due to this design, the worm gear reducer can be mounted in various ways within the machine or application. Additionally, various accessories are available for easy installation.


Transmission Ratio

The worm gear transmission is available in ratios from i=7.5 to i=100. With a double worm gear transmission, ratios of up to i=10,000 can be achieved.


Options On The Worm Gearbox

The JRST / NMRV types are equipped with an IEC mounting flange type B5 (large flange) or type B14a (small flange). This allows standard IEC motors to be attached to the reducer.

Depending on the application, an ATEX certification may be required for the worm gear reducer. For this, you can also turn to Euronorm.

The worm gear reducers are available within the scope mentioned below:

  • Construction sizes from 25 to 150
  • Torques from 14Nm to 3,000Nm
  • Output shaft sizes from 11mm to 50mm
  • Gear ratios from i=7.5 to i=10,000
  • Power ratings from 0.06kW to 15kW


Quality Of The Worm Gearbox

The quality of the drive is guaranteed by producing exclusively under UNI EN ISO 9001:2008 standards. Supplied materials are also rigorously inspected and chosen for their proven quality.

The use of A-brand wear parts such as NSK bearings and Simrit oil seals, finely machined components, and the application of precisely hardened and ground gears (grade 6) ensure a long lifespan, minimal noise, and high efficiency.
