Q&A
How to Choose a Suitable Slew Drive
There are many types of slew drives, which can be selected taking
into account the following factors.
1. Carrying capacity, direction and performance: slewing drive is
suitable for low speed and light load
2. Allowed speed: For different driver types of slew drives, in
general, bearings with small friction and low heating capacity are
suitable for high speeds. The design should strive for rotary
rolling bearings to work under conditions below their ultimate
rotational speed.
3. Rigidity: When the bearings of the slew drive unit bear the
load, the bearing ring and the contact place of the rolling body
will produce elastic deformation, the deformation amount is
proportional to the load, and its ratio determines the bearing
rigidity size. The rigidity of the bearing can generally be
improved by the pre-tightening of the bearing. In addition, in the
bearing support design, considering the combination and arrangement
of bearings can also improve the bearing support stiffness.
4. Tuning performance and installation error: After the bearing is
loaded into the working position, poor installation and positioning
will be caused by manufacturing errors. At this time, due to the
shaft fishing and thermal expansion and other reasons, the bearing
bear too much load, causing early damage. Automatic centering
bearings can overcome defects caused by installation errors on
their own and are therefore suitable for such uses.
5. Slew drive installation and disassembly: tapered roller
bearings, roller bearings and tapered roller bearings, etc., belong
to the inner and outer ring can be separated bearing types (that
is, so-called separated bearings), easy to install and disassemble.
