The Type SA drive is the latest generation of Rotomission technology.
This compact differential consists of three elements which are mechanically
connected by the sun and planet gears. Combining the motion of the three
elements solves many electro-mechnical drive problems. It employs a compound
epicyclic system of gearing to provide high-torque capacity and a wide range
of reduction ratios in a compact space. The torque capacity is a direct
function of the number of planetary gear assemblies used. Consequently,
a maximum range of ratios and capacities are provided from a minimum number
of basic sizes and components. Many sizes are available to meet output torque
and casing speeds. Andantex, Wanamassa, NJ. Free info--Circle

V-belts. Dynam series
V-belts ensure belt tension by providing two clearly-printed marks that
can be measured against a pre-specified distance. Risks of slippage are
reduced to 1% with 95% power transmission efficiency guaranteed. Correctly
tensioned belts minimize the load on bearings necessary for efficient contact
between balls or rollers and their track. Vibration and noise are reduced
while belt life is increased. Colmant Cuvelier, Lille Cedex,

Planetarygearboxes. These swiss-made gearboxes are available in 22 to 120mm
dia., with motor speeds up to 5000 rpm and typical 10,000 hr life. Low and
extra-low backlash and heavy-duty torque versions are available. Designed
to fit most common motors, mounting configurations include hollow shaft,
double-shaft, square, round, motor-larger-than-gearbox and vertical installation
position. MAXMAR Controls Inc, Pleasantville, NY. Free

In-line gear reducers.
Available for motorized inputs from 1/4 to 7-1/2 hp, the aluminum-housed
LeeCENTRIC series in-line gear reducers are designed with modular mountings
to match the footprint of other popular reducer brands. Leeson Electric,
Grafton, WI. Free info--Circle 650. http://www.OneRS.net/107df-650
Helical servo gearhead.
Ultra-TRUE continuous duty helical servo gearhead generates less heat
than other gearheads. It can run up to 1.5 times faster than standard input
speeds with 98.5% mesh efficiency. Thomson Industries Inc,
Port Washington, NY. Free info--Circle 651. http://www.OneRS.net/107df-651
Custom gear drives. Right-angle
Crown gear drives can be customized to provide directional motion change
in all types of power transmission systems. Custom features include many
shaft options, case modifications for unique mounting requirements and special
finishes. Drive gears are permanently mounted to drive shafts with locking
pins to provide a resilient and durable connection under heavy loads. Zero-Max
Inc, Plymouth, MN. Free info--Circle 642. http://www.OneRS.net/107df-642
Gearheads. Available
in metric and NEMA sizes, low-backlash high-speed gearheads are in-line
and right-angle configured, in ratios from 3:1 to 1500:1. All standard gear
head products can ship within 72 hours. Parker Hannifin--Zenith Division,
Sanford, NC. Free info--Circle 652. http://www.OneRS.net/107df-652
Pancake motor. The
Platinum series pancake motor with integral ball screw has extremely high
acceleration, zero cogging, flat profile and long life. Thrust loads are
up to 300 lbs and speed is up to 16 in./sec, with 8-in. travel. PMI/Danaher,
Amherst, NY. Free info--Circle 653. http://www.OneRS.net/107df-653
Interplanetary gearbox.
Designed for applications where diffusive power transmission is required,
the Kopernican-IXß gearbox features a revolutionary sungear that drives
9.5 planet gears, along with interorbiting satellite gears, dissipating
power evenly throughout the system. Electronic filtering reduces radio interference
from the self-lubricating ferrous-coated sun gear. Options include oort
and kuiper belt drives. Cosmic Gearheads Inc, Flying H, NM.
