IP66 Small Size Slewing Gear, Self Locking IP66 For Solar Ground
Mounting System
Slewing Gear Description
Compared with the traditional gear transmission, the worm gear
transmission can obtain a relatively larger reduction ratio. In
some cases, the reducer parts can be omitted for the main engine,
thereby reducing the purchase cost for customers, and also greatly
reducing the occurrence of main engine failure.
The worm gear slew drive has the characteristics of reverse
self-locking, which can realize reverse self-locking, that is, the
gear can only be driven by the worm. This feature makes the slew
drive be widely used in solar energy, antenna, lifting,
high-altitude operations and other equipment. While improving the
scientific and technological content of the main engine, it also
greatly improves the operation stability and safety factor of the
main engine.

Q&A
Why does the received slewing drive make abnormal noise when it is
powered on?
First of all, when the slewing drive is idling just after leaving
the factory, because the motor or the slewing drive has not been
completely run-in, there will be a small abnormal noise. This is a
normal noise, and it will disappear automatically after running in
for a period of time. If there is a loud noise, you need to
troubleshoot as described below.
Uneven mounting surface and loose mounting bolts
When abnormal noise occurs, firstly, you need to confirm whether it
is a problem with the installation operation. When the mounting
surface is uneven or the mounting bolts are loose, the slewing
bearing will be elastically deformed, and it is necessary to check
immediately and tighten the bolts as required.
There is a foreign body in the slewing bearing
When there are foreign objects such as sand particles and iron
filings inside the slewing bearing, non-periodic vibration will
occur, and at the same time, there will be a failure of inflexible
rotation. When this happens, it is necessary to clean the bearing,
shaft, seat hole and matching parts before installation, and remove
the foreign matter in the lubricant in time.
Abnormal noise caused by grease problem
The lack of grease in the raceway, uneven grease filling, poor
quality and aging of grease, and wrong selection of lubricants will
also cause abnormal noises in the excavator slewing bearing. To
solve this problem, you only need to use lubricant, add it in time,
and replace it in time.
