Abstract
The invention discloses a machining method of a slewing bearing. The method comprises a machining procedure of an outer ring, a machining procedure of an inner ring and the assembly of the slewing bearing. The machining procedure of an outer ring comprises the steps of rough turning machining, first-time boring lathe machining, semi-finish turning machining, first-time finish turning machining, hobbing machining, raceway quenching machining, tooth quenching machining, machine tool shaping machining, tempering machining, second-time finish turning, drilling machine machining, turning and grinding machining and second-time boring lathe machining. The machining procedure of the inner ring comprises the steps of rough turning, first-time boring lathe machining, first-time finish turning machining, hobbing machining, raceway quenching machining, tooth quenching machining, machine tool shaping machining, tempering machining, second-time finish turning machining, drilling machine machining machining, turning and grinding machining and second-time boring lathe machining. The assembly of the slewing bearing comprises assembling the machined outer ring and the machined inner ring. With the machining method of the slewing bearing of the invention adopted, abrasion resistance is improved, long-time stable operation is facilitated, and maintenance cost is reduced.
Description
technical field [0001] The invention relates to the field of slewing support processing technology, in particular to a slewing support processing method. Background technique [0002] The slewing bearing is a large bearing capable of bearing comprehensive loads, and can simultaneously bear large axial and radial loads and frivolous moments. Slewing supports are widely used in real industry. [0003] At present, the slewing bearing equipment usually adopts a single-raceway slewing bearing, and the drive is transmitted through the meshing of the inner and outer ring gears, that is, the slewing bearing can have a ring with a gear, an inner ring with an inner gear or an outer ring with an outer gear. When installing, Generally, the gearless gear is fixed on the main part of the host equipment, and the gear ring is used to transmit power and drive the rotation. The general slewing support device is to set the plugging hole on the outer ring surface of the love outside, and the ...
