Renold Gears has extended its SMXtra range of shaft
mounted helical gearboxes, for heavy duty applications, to
include sizes 11 and 12 that match the largest equivalent
units from Fenner, Benzler Sala and Dodge. The ATEX
approved range is now available in 12 sizes up to 235kW
capacity with a choice of single or double reduction units
with ratios of up to 25:1 and output speeds from 10 to
400rpm.
The SMXtra gearbox range is manufactured with hardened,
profile ground single helical gears with high capacity
bearings to ensure maximum power transmission, maximum
load carrying capacity and longer life. The units mount
directly onto the shaft of the driven machine completely
eliminating alignment problems as there is no need for
couplings, base plates, slide rails or support structures.
They are ideally suited to heavy-duty applications in
hostile environments and provide the ideal drive for many
types of machinery.
Depending upon requirements the SMXtra range can be fitted
with advanced seals to optimise protection from dust and
moisture. Additionally, by reversing one element of the
standard design, the seal can provide additional security
to prevent the egress of oil into sensitive environments
such as in food manufacturing. Renold Gears has produced a
new catalogue for all the gearboxes in its SMXtra range,
including the new sizes 11 and 12, with details of the
power ratings for each unit.
