Varvel takes pride in the fact that they offer a modular format gearbox. These are available in what they refer to as 'kit form' allowing you to spec a gearbox exactly to your requirements.
Available in a huge variety of shapes, sizes and ratios, and even in ATEX rating in some series, these gearboxes are both priced well and suited to industrial demands. Due to the huge numbers of options, we ask that you call to spec these after browsing the range here on the site.
Varvel RO | RO2 Series
Varvel's helical bevel gearboxes are manufactured with two and three reduction stages and are designed for fractional and medium powers as mainly used in conveyor driving. The gearboxes are especially suitable for outdoor applications thanks to long-lasting and service-free operation. RO-RV Series is designed according to ISO design standard and the robust framework is not subjected to significant buckling under running torque and external loads with positive outcome on oil seal tightness. Solid output shafts, foot, flange or torque arm fixing are fully available.
Varvel RD Series
The helical gearboxes Series RD feature a one-piece cast housing complete with inner support to accommodate 2 or 3 gear stages into the same casing. Manufactured to 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 helical gearboxes Series RD are manufactured in B3 base mounted configuration. They can be easily converted to B5 flange mounting by fitting of the appropriate additional adaptor flange.
Single-setup machining on state-of-the-art CNC production lines, the most recent calculation techniques and process controls give superior operational reliability, maximum output torques, high overhung and thrust load capacity, and long working life-time.
Varvel RG Series
RG Series planetary gearboxes are designed as one and two stage versions, with hardened and tempered steel housing and broached internal gear. Manufactured to latest ISO engineering design specifications is checked by computer-aided structural analysis for deflection and stress distribution. Significant strains caused by the effects of both torque and external loads do not stress the monolithic housing, substantially improving the sealed surfaces. Epicycloidal speed reducers RG are made of alloyed steel gearing, hardened and tempered; the planetary gear shafts of tempered steel. Motor coupling options are available with clamping clutch, input flange and bush adapters. Single-setup machining on state-of-the-art CNC production lines, the most recent calculation techniques and process controls give superior operational reliability, maximum output torques, high overhung and thrust load capacity, and long working life-time.
Varvel RVR | VS Series
The mechanical speed variators are designed according to a proven system that provides strict quality control at every stage of production. The goal is to provide the customer with a variable speed drive that is both reliable and easy to assemble, in respect of what the safety regulations are in many different areas (potentially explosive atmosphere, food & beverage and so on). The attention to detail, the deep experience of over 60 years, and not least the use of the latest machinery and software technology enable the full achievement of this milestone.
Varvel RN Series
Shaft Mounted gearboxes are made for light industry applications like the drive of belt conveyors. Due to their long-term reliability and reduced maintenance requirements are particularly suitable in outdoor installations. RN Series, parallel shaft gearboxes, are designed according to latest ISO engineering specifications with the help of computer aided structural analysis for displacement and stress field. The shaft mounted version allows the flange mount B5 conversion by simply fitting one of the many output flanges available. Various dimensions and types of output shafts are available for the majority of applications.
Varvel RS – RT – RA – TA – RS/RS – RT/RT Series
Varvel's high quality worm gear motors, made in cast aluminium and cast iron in 6 different series, combine innovative design and high performance. From the models that power applications with medium and fractional power to similar solutions (RS / RS and RT / RT) with double worm. See our complete range of speed reducer and industrial motor worm gearboxes and find the most suitable for your needs.
