In terms of bearing capacity, the performance of the worm gear type is better than that of the tooth type, and when the enveloping worm drive is used, its bearing capacity, deformation resistance and transmission rigidity are further improved. However, the worm gear slewing drive is inferior to the gear slewing drive in terms of efficiency. According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into an open housing slewing drive and a closed slewing drive. http://www.ldb-slewdrive.com/open-housing-slewing-drive/
