The slewing drive is a gearbox that can safely hold radial and axial loads and transmit torque for rotating. The rotation can be on a single axis or multiple axes together. Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor, and other auxiliary components and assembling them into a finished gearbox.Slew drive is a new series of slewing products named slewing reducer. It is commonly composed of the worm, slewing bearing, housing, motor adapter, end cap, and other components. By adopting slewing bearing as its core component, slewing drive can simultaneously handle axial force, radial force, and tilting moment. Compared with the EWA series slewing drive, the EGA series has the advantages of better defensive performance, excellent transmission torque, better impact resistance, and long working life.To judge what kind of slewing drive you need, you have to clear out the configuration of the slew drive and the purpose of the equipment. Each unit will have differing specifications. When defining the type and capability of the slew drive, the following variables are calculated:(1) Gear ratios(2) Precision(3) Weight(4) Output(5) Tilting moment(6) Torque(7) Dynamic and static axial(8) Radial dynamic

The Installation Method and Precautions of Slewing Drive

1. Preparation before installation of slewing drive
(1) Clean the slewing drive and installation structure:Remove foreign matter from the mounting support surface, such as paint residue, solder beads, burrs, etc. The corrosion protection coating on the slewing drive bearing surfaces should also be removed. Be careful not to infiltrate the cleaning fluid into the slewing drive; do not use cleaning materials that will corrode the seals.(2) Inject lubricating oil into the slewing drive device:The slewing drive has been filled with grease before leaving the factory, but before the initial operation, it should be lubricated again, especially for the slewing drive that has been stored for a long time. It should be ensured that the slewing drive is completely lubricated. The grease must be the one specified on the delivery drawing.(3) Select the appropriate mounting bolts:• Use the bolt size, quantity, and quality grade specified in the installation instructions.• A clamping ratio (clamping length to bolt diameter) should be observed from a minimum value of ≥5 to a maximum weight of ≤10.• Bolts with fully threaded shafts are not permitted.• Failure to comply can affect the bolted joint's functionality and longevity, and durability.• If the allowable interface pressure is exceeded, use a suitable size and strength gasket.• Do not use old bolts, nuts, and washers.(4) Selection of tightening torque:• Under normal conditions, the mounting bolts are fully secured with the correct preload.• Mounting bolts can be secured with a Loctite thread locker.• Split rings, split washers, etc., are not permitted.• If using washers, make sure they have the correct strength class.
2. The process of installing the slewing drive
(1) Position the slewing drive and fix it with bolts:• Lightly lubricate bolt threads to ensure even frictional resistance (does not apply to bolt locking devices with adhesive).• Cross preload bolts, including washers in three steps with 30%, 80%, and 100% tightening torque or hydraulically applied preload.• Repeat the above steps for bearing rings that are not yet bolted.The preload should not exceed 90% of the yield stress when using hydraulic fastening devices.(2) Determine the existing tilt clearance and backlash:• Tilt clearance increases with raceway wear. The permissible increase in tilt clearance is 1.5 to 2 mm. To determine the rise in tilt play, basic measurements must be carried out after installation and before the slewing drive is put into operation for the first time.• The increased backlash signals gear wear. The amount of backlash allowed depends on the slewing drive applied.• Record all measurements.All measurements are made at the same point, the same load, the exact position of the bearing rings relative to each other, and in the same order. All measurements should be recorded. Check for tilt clearance for axial or radial loads by applying additional tilt load.(3) Operation test:If the slewing drive is installed correctly, the slewing drive should rotate evenly, and factors such as the deviation of the installation structure and external loads will affect the friction torque.• Rotate the mounted slew drive several times.• Check that the slew drive is smooth and free of jumping.• Carry out further test runs under full load.After running the test, recheck the tightening torque of the mounting bolts.

Slewing drives are used worldwide for:

• Vehicle and crane systems.• Rotation of attachments such as excavators, hydraulic tongs, and forklifts.• Facility management (automated systems).• Loading and unloading equipment.• Positioning Systems.EGA5 Series Slewing Drive
