Slewing Drive Gearboxes
This wide range includes gearboxes for slew drive of excavators, all kinds of mobile cranes, tower cranes of construction sites, harbour and deck cranes, aerial work-platforms and solar-trackers (large photo voltaic panels and wind power equipment). A large selection of reduction ratios are available for all sizes, along with built-in negative brakes and adaptors for all the most common hydraulic and electric motors.
The high capacity bearings on the output shaft are designed to take the heavy radial loads due to the slew ring/pinion gearing.
The slew pinions are available with many different modules and number of teeth to suit the various kinds of slew rings.
The range covers 15 different sizes for torque from 1.000 up to 130.000 Nm.
Slewing ring, also known as slewing bearings or turntable bearing, is a large bearing which is able to sustain the more axial load, radial load and tilting moment. It is known as: “machine joints”, the essential machinery transmission parts, between the two objects that need to be relative rotary motion. It has the inner and outer ring, rolling and other components.
One can consider the slewing drive as a gearbox because the core motion components are the slewing bearing and worm shaft. It also consists of auxiliary components such as seals, housing, and motor. As a power source, slew motor is usually DC planetary gear motor or AC gear motor. AC hydraulic motor is mainly used in the construction machinery as a power drive system. As the core component is slewing ring drive, slewing gearbox can readily withstand the axial and radial forces. The slew drive working principle: The worm is driven by the motor, which drives the outer ring of the slewing ring to rotate; The outer ring output the torque through the flange and the inner ring of the slewing ring is fixed in the housing.
Slewing drive gearboxes has reverse self-locking because of worm gear drive with reverse self-locking characteristics. This feature greatly enhances the stability of the host operating and safety factor. Compared to the traditional swing products, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
1.Hourglass worm technology provides more tooth contact, higher torque
2.Provide an economical and compact solution with low maintenance costs
3.Slewing gear and raceway harden processing technology increase the slew drive lifetime
4.All slewing mechanism components are rigorously tested and have good quality assurance
5.Custom design is available
6.Types: Single axis Slew Drive, Dual Axis Slew Drive, Open-Housing Slewing Drive, Enclosed Slewing Drive, Vertically-Mounted Slewing Drive
Slewing drive is a perfect motion control product for the application which requires rotational torque strength.
1.Slew Drive For Solar: it is designed in solar photovoltaic panel rotation and improves power generation efficiency. Single axis & dual axis solar tracking solutions are available. Power Jack Motion slewing drive for solar tracking system application include solar Concentrator Solar Dish, CPV (Concentrated Photovoltaics), CSP (Concentrated solar power), solar parabolic trough, PV tracker
2.For wind generators: Slewing drives are used to rotate the pedestal in wind turbines
3.Slewing Drive for Construction Machinery Application: widely applied on mounted truck crane, aerial working platform, Dock Crane, Timber Grab
4.For Industry Market: Automation/Assembly line, robotic arm
5.For Satellite: slew drive can be used for space communications and global positioning systems in satellite dish
