TEC Electric Motors worm gear boxes are constructed with an air tight and dust proof aluminium gear casing (sizes 025-090) and benefit from being able to be installed in open air. No extra servicing is required for our worm gear boxes which are supplied with synthetic oil and are sealed for life. Sizes 110-150 are lubricated with mineral oil and supplied with breather, drain and filler plugs.
Suitable Applications for Worm Gear Boxes
Our gear boxes are suited for uses such as conveyor systems, thermal power plants, crushers, cranes, bail mills, cooling towers and extractors. Worm gear boxes are commonly used in all kinds of industry including the paper, sugar, textile, solvent extraction, plastic and leather processing industries as well as power plants, steel industry and waste water treatment.
Custom Specification Gear Boxes
If you require custom specification worm gear boxes, we have the expertise and experience necessary to custom spec worm gear boxes which match your bespoke requirements. We work from supplied drawings and no individual specifications. For more info, click here to contact us directly via out contact form.
The series RD helical gearboxes feature a one-piece cast housing complete with inner support to acommodate 2 or 3 gear stages into the same casting. Manufactured to the latest ISO engineering design specifications, the housing is checked by computer aided structural analysis for deflection and stress distribution.
Significant strains caused by the effects of torque and external loads do not deflect the monolithic ribwork of the housing, which significantly improves the integrity of the sealed surfaces.
The series RD Helical gearboxes are manufactured in B3 base mounted configuration. They can be easily converted to B5 flange mounted by fitting of the appropriate additional adaptor flange.
Single setup machining on state of the art CNC production lines, the most recent calculation tequniques and process control gives superior operational reliability, maximum output torques, high overhung and thrust load capacity and long working life times.
The series RD are made up in 7 sizes and output torques of 20Nm to 2500Nm are available.
Single worm gear boxes
The worm gearboxes, RS and RT series, specifically designed for universal mounting, are manufactured with die cast housing and covers in aluminium up to the size 85 and cast iron from the size 110.
Torques listed in the selection tables are output torque values for the specific size and motor powers are always referred to at 1400rpm.
Gearboxes are supplied filled with synthetic long life oil.
Helical worm gear boxes
The gearboxes, RA and TA series, made up of an independent single stage helical gearbox FXA fitted to a standard FRS or FTR gearbox, allow greater output torque and higher efficiency than the FRS and FRT gearbox with equivalent ratios.
Two stage worm gear boxes
The gearboxes, RS/RS and RT/RT series, are made up of two gearboxes RS or RT and offer a full selection of high reduction ratios to obtain the very low output speeds.
The gearboxes, series RN, RO, RV are manufactured with a common housing that allows the same footprint for the three versions and are designed according to latest ISI engineering specifications with the help of computer aided structural analysis for displacement and stress field.
The monolithic framework does not deflect under the effect of torque and external loads with effective results on sealing sufaces.
The gearbozes RN, RO, RV are manufactured of pressure die cast for the first 3 sizes and of cast iron for the others. The shaft mount version, common to the three styles, allows the flange mount B5 conversin by simply fitiing one of the many output flange options available.
The series RN, RO RV are made in 6 sizes with output torques between 100 to 3400 Nm.
