Bologna, BO, Italy, 2015/02/25 - Varvel SpA meets specific needs of the international market with a dedicated application of the gearbox RB13 for boilers and pellet heaters at the Energiesparmesse in Vienna - Varvel.com.
Varvel SpA, since 1955 specialized in designing speed reducers and variators, meets the requests of the international market by first presenting the parallel shaft gearbox RB13 at the Energiesparmesse in Wels, Austria.
RB13 features an IEC56-B14 input motor flange, directly cast into one of the aluminum semi-casing. Three sets of gears are set in line with the input pinion directly fitted onto the motor shaft. The gearbox is specifically designed for pellet heaters.
From February 25 to March 1, at the Hall 20 stand 2010 of the Austrian tradeshow, customers will first look at the new reducer, designed and produced internally; a new gearbox, specially oriented to pellet heaters ensuring increased performance and a significant noise reduction.
In order to further improving the gearbox noiseless on operation, a new version will be available shortly with input pinion directly cut on the motor shaft that will keep under control potential alignment or concentricity errors.
This helical gear is made in two reduction ratios (3.95 and 8.50) allowing a wide range of final ratios (as example 41.12 69.81 83.38 88.94 109.0 117.46 140.72 177.99 221.07 254.20 271.16).
Electric motor sizes are available for the powers 60W, 90W and 120W, according to the reduction ratio selection.
The gears are calculated on a 10,000 hour lifetime and for a maximum output torque of 60Nm.
The output shaft is hollow with bores ø17mm and ø20mm with standard keyway, and ø25mm without keyway.
The housing is suitable for shaft mounting with four through holes ø8.5mm, interchangeable with the majority of competitors.
Four additional blind holes on PCD ø85mm are available for mounting the RT/RS50 output flange with self-tapping M8 screws.
“In the year of our 60th anniversary, we face the future by counting on technologically advanced solutions representing our answers to specific issues. Varvel earned the market trust by nurturing relationships with its stakeholders: RB13 is just the latest evidence” say Francesco Berselli and Mauro Cominoli, President and General Manager of Varvel SpA.
