What is slew motor?

What is slew motor?

Slew motors, also referred to as swing motors or swing drive motors, provide rotation. For example, a slew motor is what enables the house of a mini excavator to rotate 360°. On excavators (wheeled, tracked, and compact), they are usually axial piston hydraulic motors.

What is excavator Slew?

Slewing refers to rotating the excavator’s house assembly. Unlike a conventional backhoe, the operator can slew the entire house and workgroup upon the undercarriage for spoil placement.

What is a swing motor on an excavator?

Swing motors are core elements necessary for the operation of excavators. Swing motors are hydraulic motors that form the proper turning force of excavator booms using oil pressure, shift rotation either to the right or left and convey or cut off turning power.

How does a slew motor 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.

What is a slew drive used for?

Slewing drives are widely used in aerial work platforms, hydraulic equipment attachments, materials processing, construction, and various types of utility equipment because they’re the best tools for performing tough work. They are durable, powerful, and easy to operate day after day.

What is a slewing bearing used for?

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 …

How many times can an excavator swing?

An excavator only has a digging bucket – or other attachment – on the front end. A backhoe has a rotation radius of 200 degrees while the excavator can rotate a full 360.

What is slewing system?

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and assembling them into a finished gearbox.
