Description
Recently, the need for more silent,
powerful and at the same time economical gears of all types and
sizes is growing. A significant proportion of gears constitute
bevel gears with circular tooth line. Hypoid gearings are used in
power transmission products that are more efficient than
conventional worm gearing. They are considerably stronger and have
more capacity in that any load is conveyed through multiple teeth
simultaneously. By contrast, bevel gears are loaded through one
tooth at time. The multiple contacts of hypoid gearing, with proper
lubrication, can be nearly silent, as well. They are widely used in
vehicle transmissions, shipbuilding, metallurgical equipment,
construction and crushing equipment and other industrial sector
using large modular bevel gears especially with helical
teeth.
Spiral bevel gear generator
5A**4 is used to produce of hypoid gears, spiral bevel gears, zerol
conical gears with maximum outside diameter of ***0 mm and maximum
modul of *0 Machining is performed by face-type gear
cutter head, using the methods of generation and approach cutting.
Model 5A**4 have very high accuracy, the machine ensures class 7 or
more depending on the cut format adopted. As option machine can be
equipped SIEMENS Simatic S****0 control system, SIMODRIVE **1U
Drive.
Technical and operational
features
Machining cycle is carried out
automatically. The feed in generation or approach cutting is
provuded by one electric drive. The permanent fast approach speed
does not depend on the duration of the cycle. The adjustment
motions of mobile units are power-driven. The semi-automatic
machine-tool serves many purposes, it is easily readjustable from
one workpiece to another.
Hypoid gears are typically found within
the differential (rear axle) of automobiles, but also for heavy
engineery products in crusher, in mining equipment, gearboxes,
reducer, oil field rotaries, coal pulverizers, rock crushers, paper
pulpers, cement separators, cooling tower drivers, pump drives,
steel mill roll drives, bow thrusters etc. The gear arrangement
allows the translation of torque ninety degrees. Hypoid gears are
similar to spiral bevel gears except that the shaft center lines do
not intersect. Hypoid gears combine the rolling action and high
tooth pressure of spiral bevels with the sliding action of worm
gears. This combination and the all-steel construction of the drive
and driven gear result in a gear set with special lubrication
requirements, including oiliness and anti-weld additives to
withstand the high tooth pressures and high rubbing
speeds.
Spiral bevel gear have a helical angle
spiral teeth.
