Slewing drive hi an variable speed transmission a zirin gear leh worm gear chi hrang hrangah then theih a ni. Gear leh worm gear transmission pahnih ziarang rochun, heng slewing drive chi hnih hi medium- atanga high-speed leh low-speed application atan a tha hle. Worm gear chi hrang hrangte hian load capacity lamah gear chi hrang hrang an phak lo hle a, enveloping worm drive hman a nih chuan an load capacity, deformation resistance leh transmission rigidity te chu a ti tha zawk a ni. Mahse, worm gear slewing drive hi gear chi hrang hrang aiin a efficiency lamah a hniam zawk a ni.
Slewing drive te hi an transmission sub-mechanisms openness a zirin open leh closed type ah then theih a ni. Open structure hi hmun harsa takah hman a ni tlangpui a, maintenance leh servicing cycle tawi tak a awm bawk. Open structures hian components enfiah, enkawl leh thlak danglam a ti awlsam hle. Chumi danglamna chu, closed structure hian environment condition inthlak danglam lo zawk leh pollution level medium hnuai lam application-ah service life rei zawk a pe a ni.
