HBW SHORT PROFILE SAILING GEAR
DESCRIPTION
1. BRIEF DESCRIPTION
The Type HBW Short Profile Sailing Gears are equipped with a positively driven, mechanically
operated helical gearing system. The servo-operated multiple-disc clutch requires only minimum effort
for gear changing, making the transmission suitable for single-lever remote control via a rod linkage,
Morse or Bowden cable.
The torque transmission capacity of the clutch is exactly rated, preventing shock loads from exceeding
a predetermined value and thus ensuring maximum protection of the engine.
The transmission units are characterized by low weight and small overall dimensions. The gearbox
castings are made of a high-strength, corrosion-resistant aluminum alloy, chromized for improved sea
water resistance and optimum adhesion of paint.
The transmissions are immersion-lubricated. Maintenance is restricted to oil level checks (see
"Maintenance").
2. GEAR CASING
The rotating parts of the HBW transmission are accommodated in an oil-tight casing divided into two
halves in the plane of the vertically axis. Amply dimensioned cooling ribs ensure good heat dissipation
and mechanical rigidity.
