What is winch gear?
The Zollern winch gearboxes are planetary gears, which are fully integrated in the rope drum. The winch gearboxes are based on a modular system. They are available with an extended scope of delivery, such as with a motor, coupling and brake, and can easily be integrated into the rope winch.
What is slew gearbox?
The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together.
How do winch gears work?
Johnson explains it in basics: The winch motor turns a shaft connected to the first sun gear, which is engaged in a set of planetary gears that reduce the gear ratio. This first set of planetary gears transfers torque through a carrier into another sun gear, which turns the next set (or stage) of planetary gears.
How do slew drives work?
In operation, the slew drive’s axial movement, or motion around its axis, interacts to create radial torque. The action occurs by meshing the grooves of the horizontal screw with the teeth of a perpendicular gear. While turning, the worm gear’s axial movement transfers magnified torque force to the radial gear.
How do slew rings work?
Two concentric rings make up the main structure of a slewing bearing. The outer ring usually lies flat against a motionless surface and is screwed into place via evenly spaced mounting holes. The inner ring is usually affixed to a turning object via an adapter plate or bracket.
What is the best gear ratio for a winch?
about 150:1 to 300:1
Gear ratios range from about 150:1 to 300:1, giving the winch its pulling power. Just as with your axle gears, higher numeric ratios provide more power, but at the expense of speed. A good winch design matches the electric motor power and gear ratio to provide a desirable compromise between speed and pulling power.
Which motor is used in winch?
Winches use two types of DC motors, Permanent Magnet Motors and Series Wound Motors. All electric DC winch motors consist of one set of coils, called an armature, inside another set of coils or a set of permanent magnets, called the stator.
Do winches work both ways?
Helpful Expert Reply: Yes, the motor in the Superwinch LT3000ATV Winch, part # SW1130220, operates in both directions (both feed out and pull in).
What is needed to operate an electric winch?
Electric winches require power from a battery to be operational. With proper wiring, power can be provided to the winch through a vehicle battery or through a separate, auxiliary battery that powers the winch only.
What is a slew engineering?
The slew rate of an electronic circuit is defined as the rate of change of the voltage per unit time.
What is slew ring connection?
A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the …
Why choose a Zollern gear?
ZOLLERN gears use components common to our complete range (Winches, Slewing Units, Industrial Gears, Free Fall Winches) giving the advantage of volume production: cost savings from standard parts, reduced lead times, tested and proven designs across the whole range and readily available spares for units in service. The ZOLLERN Group
Who makes Zollern gearboxes?
ZOLLERN has been producing planetary gearboxes since 1972. In 2001, the brand “Dorstener” and its gearbox technology for spur gears, bevel gears and planetary gears was acquired by the ZOLLERN Group. ZOLLERN gearboxes and cable winches can be found in all maritime applications around the world.
What are the application areas of Zollern?
Typical application areas are ship cranes, heavy duty cranes, floating cranes, dredgers, lifeboat winches or jack-up gearboxes for offshore platforms. On land, for example, ZOLLERN moves mobile harbour cranes, shipyard cranes and handling equipment.
What does Zollern stand for?
The ZOLLERN brand stands for excellent quality, reliability and innovation on ships, in harbours and on offshore platforms. Typical application areas are ship cranes, heavy duty cranes, floating cranes, dredgers, lifeboat winches or jack-up gearboxes for offshore platforms.
