Horizontal or vertical, right angle
or parallel foot mounted or shaft mounted gear units
Crescent helical gear units are fully metric and are suitable for most
application in both horizontal and vertical drives.
Based on a modular design and construction, the high degree of
interchangeability of parts and sub-assemblies among all variants effects
considerable economies of production, whilst maintaining the highest
standard of component and unit elements. A wide choice of ratio is available
based or recommendations laid down in AGMA standards with additional half
Profile ground helical gears together with spiral bevel gears lapped in
pairs, ensure high standards of accuracy, surface finish and quiet running
characteristic. Helical gears are fitted in parallel shaft units whilst
units with shaft at right angle incorporate spiral bevel and helical gears.
High quality alloy case hardening material provide long life wear resistance
and fatigue strength
The high power to weight ratio of all units combines with low volume to
enable installation in the most difficult situations. Each of the two
variants contains unique features suited to their own operating conditions.
Horizontal units feature optional right or left hand shaft arrangements
from the same sub-assemblies and are available as foot mounted shaft mounted
or foot/shaft mounted types.
Vertical unit are available in three versions: Standard units, heavy duly
stirrer types and cooling tower drives.
