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.
