Geared Motors

VARVEL, an Italian company established in 1955 and based in Northern Italy, manufactures speed reducers and mechanical variators in house to IS09001 standard.

Products include:

  • RS/RT : Right Angle Worm Gearboxes
  • RD/RC/XA : Helical In-Line Gearboxes
  • VR/VS : Mechanical Variators
  • RN : Shaft Mounted Parallel Gearbox
  • RO : Horizontal Bevel Helical Gearbox
  • RG : Planetary Speed Reducer

Each of these units can be assembled with various inputs to suit your existing Motor or with Free Shaft input and there are several output mounting arrangements.

  • The gearboxes of series RN, RO, RV are manufactured of pressure die cast for the first 3 sizes and of cast iron for the others.
  • Various dimensions and types of output shafts (hollow with through keyway, hollow with shrink disk and solid with single or double end) are available for the majority of applications.
  • The series RN, RO, RV are made in 6 sizes for each type of gearboxes, 30 reduction ratios and output torques between 100 and 3400 Nm.

RT Worm Geared Units


RS - Modular Design with Optional Mounting Arrangements

  • The RS Worm Gearboxes, specifically designed for universal mounting,are manufactured with die cast housings and covers in aluminium up to the size 85 and cast iron from the size 110.
  • Input Viton oil seals, fitted on demand, allow free-trouble operation with either 2-pole, or 4 pole, standard AC Motors or 3000 rpm DC Motors.

RT - Traditional Square Design

  • The RT Worm Gearboxes are designed to easily interchange with customers existing Units and like the RS are manufactured with die cast housings and covers in aluminium up to the size 85 and cast iron from the size 110.
  • Input Viton oil seals, fitted on demand, allow free-trouble operation with either 2-pole, or 4 pole,┬ástandard AC Motors or 3000 rpm DC Motors.

RC Series Helical In-Line Units


The Series RC helical gearboxes are manufactured to latest ISO engineering design specifications.

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.

Leading applications:

  • General purpose
  • Medium and fractional power drives

Design:

  • Cast iron housings and covers
  • One-, two-, and three-gear trains

RP Series Helical In-Line Units


The gearbox FRP71 is expressly designed to be fitted on pick-up boots for feeding system screw conveyors; the gearbox/boot fitting does not comply with any standard and a wide range of fittings is offered to match the customer's need.

The one-piece aluminium die-cast body is abundantly sized to avoid any harmful vibration to the feeding system and to withstand heavy operations.

  • Helical gears - made of alloy steel, casehardened, tempered and shaved - are designed and verified according to ISO 6336 and DIN 3990.
  • Bearings are calculated for at least 15,000 running hour average lifetime
  • Keyways according to DIN 6884
  • The gearboxes are delivered filled with synthetic long-life oil (without plugs), in the appropriate quantity to install them in any mounting position without any prior specification.

Leading applications:

  • Animal livestock systems for feeder driving (screw conveyors) in floor feeding applications

Design:

  • Aluminium die cast housings and covers
  • One-gear train

XA Series Helical In-Line Units


The helical gearboxes series XA are manufactured as follows: aluminium die cast housing and covers, helical gears in alloy steel, case hardened,tempered and shaved.

Gears - designed and verified according to ISO 6336 and DIN 3990 - and bearings are calculated for at least 15,000 running hour average lifetime.

Keyways according to DIN 6884.

The gearboxes are delivered filled with synthetic long-life oil (without plugs) and in the appropriate quantity to install them in any mounting position without prior specification.

Leading applications:

  • General purpose
  • Flange mounting B14
  • Independent helical stage for fitting to FRS and FRT input

Design:

  • Aluminium die cast housings and covers
  • One-gear train

RD Series Helical In-Line Units


The Series RD helical gearboxes are manufactured in B3 base mounted configuration and in B5 flange mounting.

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.

Leading applications:

  • General purpose
  • Medium and fractional power drives

Design:

  • Housings and covers of aluminium die cast up to size 4
  • Housings cast iron from size 5
  • Two- and three-gear trains
