TORQUE-ARM™ and TORQUE-ARM™ II
The Dodge TORQUE-ARM II
surpasses all other reducers on the market because of its industry
proven design and patented features. This powerful line of shaft mounted
speed reducers – in 12 case sizes through 400 horsepower (HP) – offers
unparalleled torque ratings and is quickly becoming the new industry
standard. Improved features include: an all-new backstop concept, a
patented sealing system, a steel motor mount system, a state-of-the-art,
totally modular design with an expanded ratio range to 40:1 and a
patented twin tapered bushing system.
The increased ratings on
the TORQUE-ARM II line are comparable to the next larger sized TXT
reducer and are the result of the extended gear centers, wider gear
faces and optimized tooth geometry. The new backstop design features
centrifugal lift-off sprags for extended life and can be used with
lubricants containing EP additives. In addition, the TORQUE-ARM II line
has a patented, premium sealing system that uses an HNBR oil seal
protected by a metal excluder seal with rubbing lip. This harsh duty
sealing system makes this reducer series a perfect fit for today's harsh
duty industries such as aggregates, mining, cement, asphalt, mixing
& milling and ethanol.
The new steel motor mount adjusts to
multiple center distances and mounts in shaft mount and screw conveyor
positions. Its patented twin tapered bushing system - in standard
length, short shaft, and metric versions – offers all the features of
Dodge's standard twin tapered TORQUE-ARM® bushing design which are
unique to Dodge. The patented insertable tapered wedge enables the
optional extended tapered bushing kit to be applied for shorter shaft
lengths; allowing the replacement of straight bore or single bushed
reducers.
Both Torque-Arm II and Motorized Torque-Arm II are ATEX certified.
Motorized
Torque-Arm has been found to comply with the Essential Health and
Safety Requirements that relate to the design of Category 2 and M2
equipment, which is intended for use in potentially explosive
atmospheres. These Essential Health and Safety Requirements are given in
Annex II to European Union Directive 94/9/EC of 23 March 1994.
