Motovario have extended their range of bevel helicals to include two new larger sizes and more small sizes made with lightweight aluminium universal mounting casings
Leading power transmission specialists Motovario have extended their range of bevel helicals to include two new larger sizes and more small sizes made with lightweight aluminium universal mounting casings.
The larger sizes are designed for new markets, such as bulk material handling, conveyors and agitator/mixer applications where a robust cast iron casing is required with high torques and slow speeds through to lighter duties where the low weight of the aluminium casing lends itself for mounting directly on the drive shaft.
The bevel helical range compliments Motovario's worm gearbox range with the added benefit of high efficiency at 96 per cent.
Motovario have been particularly successful with their bevel helical range due to the efficiency for electronic variable speed drives.
Although a bevel helical unit is more expensive than a wormbox, when the efficiency and required motor power are taken into account, they are cost effective, especially with electrical variable speed drives, since smaller controllers can be utilised.
"The reason why the small end of the market has been developed is that, with the development of high efficiency motors and the environmental needs to save energy, bevel helicals are going to be a main gearbox requirement in the 21st century," said Steve Horsfall, Managing Director of Motovario Ltd, based in Rushock, near Droitwich.
"Motovario is extending and developing its range of bevel helicals with an eye on the future.
The aluminium casings make them more cost effective.
"The iron age has passed and people now accept aluminium as not only being lightweight but also as a strong material such as used in lunar modules and new top of the range cars." Features: - 8 sizes - Ratios from M.6/1 - Power ratings from 0.12KW to 30KW Inputs to suit any standard IEC, ac or dc motor Close coupled motor versions Foot mounting or flange mounting versions with hollow output bore or solid output shaft options.
