Product Description

Slewing Drive

1. Description
The slewing drive achieves the purpose of deceleration through worm driving gear. The worm is driven by a motor to drive the outer ring of the slewing bearing to rotate. The outer ring outputs torque through the flange while the inner ring is fixed on the housing.

2. Function
Our slewing drive is able to withstand large axial force, radial force, and overturning moment. It can the turntable or stand for horizontal and tilt angle rotation.

3. Application Field
a. Solar energy field
In solar power generation industry, slewing drives are often used in the tracking bracket to drive the power generation system to track the sun and thus improve power generation efficiency

b. Construction machinery field
Slew drives for construction equipment are mainly used to drive two relatively rotating objects to make rotations within 360 degrees.

4. Advantages
a. Our slewing drive adopts hourglass worm design. Multi-tooth contact gives high output torque.
b. The raceway and tooth surface are quenched, which greatly prolong the service life.
c. The exposed surfaces are processed by painting and the paint color is selected at will between the RAL series colors.
d. Our worm gearing has passed strict type test.
e. Customized products are available.
f. Our slewing drive is divided into six series, i.e., enclosed series, precise series, zero backlash series, open housing series, heavy duty vehicle series, and two-stage transmission series.
g. With the production process conforming to the ISO 9001 quality management system, the gear reducer has obtained the CE mark.

6. Installation

a. Horizontal Installation


When the slewing drive is used in the solar energy field and there is special requirement on protection class, please refer to the above picture for horizontal installation. For vertical installation, additional protective measures are required.

When the gearbox is used in other industries and there is no special requirement on the protection class, the installation mode is unrestricted.

b. Vertical Installation


When the worm drive is applied in the solar power field and there are special requirements on the protection class, the vertical installation should be conducted according to the above picture. When the slew drive is used in other fields and there is no special requirement on the protection class, the installation method is not restricted.


Types & Drawings:

1. Single axis type, such as SE7 for example (the following is an enclosed-housing type, besides we also have open-housing type)

2.  Vertical type, such as VE9 for example:

3.Dual worm type, such as SE14-2 for example (the following is also an enclosed-housing type, besides we also have open-housing type)
