StanDARD MITER GEAR ASSEMBLIES FOR SCREW JACKS
gear ratio 1:1 |
| |
| Jacks may be used in multiple
arrangements by connecting shafting, couplings and gear boxes to
simultaneously transmit power to the input shafts of the jacks.
Nook Industries provides gearboxes for use with jacks. Make certain
that the total torque and horsepower required by the arrangement
does not exceed the ratings of the box. Miter gear boxes can be
operated up to 900 rpm. Higher speeds are permissible at lower torque
ratings. Noise levels may increase at higher speeds. The operating
efficiency of a miter gear box is 90%.

Gears are forged alloy steel.
Shafts are stressproof steel ground and polished. Clockwise (CW)
and counterclockwise (CCW) notations indicate direction of shaft
rotation when facing outer end of shaft. All shaft arrangements
will operate opposite direction for that shown. To order specify
model number and desired shaft arrangement. |
