Hollow shaft gearheads are right angled, flange-mounted gearheads that
use worm gears and special helical gears. They are ideal for keeping
equipment compact. They are available in a variety of sizes. They are
locked with a torque arm when mounted so the gearhead does not rotate
from the reactive force of the load. For mounting a hollow shaft
gearhead, a coating of molybdenum disulfide or similar grease is applied
to the inner diameter of the load shaft. Coating is done to prevent
binding.Advantages of Hallow Shaft Gearheads
- They do not require couplings for mounting and thus allow additional space savings and simpler mechanism designs.
- They increase system reliability and decrease system cost by eliminating the need for separate couplings.
- They offer high gear ratio and a lower output torque.
- The hollow shaft gearheads have a peak torque rating of 7,450 in-lb and a peak radial load capacity of up to 1,798 lbs.
- They are available in various frame sizes.
Typical applications of hollow shaft gearheads include the following:
- Induction motors
- Reversible motors
- Electromagnetic brake motor
- Speed control system, and
- Synchronous motors.
