The utility model adopts the technical proposal that: the utility model provides a take super-huge double row tapered roller slewing bearing of adjusting washer, includes inner circle, outer lane and sets up the rolling element between inner circle and outer lane, and the inner circle includes first inner circle, second inner circle and packing ring, and the packing ring setting is in the position between first inner circle and second inner circle, and installs the taper pin that is used for fixing first inner circle, packing ring and second inner circle in the axial direction of inner circle, and the top of taper pin is equipped with the screw that is used for fixing the taper pin, and the screw is installed at the tip of first inner circle or second inner circle through threaded connection's mode.
And a plurality of connecting bolts for connecting the first inner ring, the gasket and the second inner ring are arranged in the thickness direction of the inner ring, and the connecting bolts are uniformly distributed around the center of the first inner ring.
The number of the taper pins is two.
The rolling body comprises a retainer and a roller, and the roller is in a conical structure.
In the process of processing the slewing bearing, in order to ensure that the clearance of the roller between the inner ring and the outer ring meets the design requirement, the upper surface and the lower surface of the gasket can be subjected to matched grinding after the first inner ring and the second inner ring are processed, the first inner ring, the second inner ring and the gasket are positioned through the taper pin after the matched grinding is finished, the taper pin is reinforced through the screw, and finally the first inner ring, the second inner ring and the gasket are locked through the connecting bolt, so that the assembly of the inner ring of the slewing bearing is finished, and the time waste of the slewing bearing in the processing stage can be reduced; after the slewing bearing is used for a period of time, the axial play of the slewing bearing is gradually increased due to the action of force on the contact surfaces of the roller and the inner ring and the outer ring, the connecting bolt and the screw can be disassembled to take the taper pin out of the position of the inner ring to achieve the purpose of disassembling the gasket, and at the moment, the upper surface and the lower surface of the gasket can be ground to meet the requirement that the axial play of the slewing bearing meets the design requirement, the slewing bearing does not need to be scrapped, and the service life of the slewing bearing is prolonged.
The inner ring comprises a first inner ring, a second inner ring and a gasket, and the gasket is arranged between the first inner ring and the second inner ring; the purpose of this is: the gasket is added, so that the processing difficulty of the inner ring of the slewing bearing can be reduced, the size requirement can be met only by adopting a matched grinding mode on the gasket during precision processing, and the processing time of the whole inner ring can be shortened; and after the clearance of the slewing bearing is increased, the defect of the increased clearance can be compensated through disassembling and match grinding the gasket, and the service life of the slewing bearing is prolonged.
The screw is arranged above the taper pin and is used for fixing the taper pin, and the screw is arranged at the end part of the first inner ring or the second inner ring in a threaded connection manner; the purpose of this is: the taper pin is used for realizing accurate positioning of the first inner ring, the second inner ring and the gasket, assembly precision is improved, the stability of the slewing bearing in the using process is facilitated by reinforcing the taper pin through the screw, and the taper pin is prevented from falling off.
The utility model has the advantages that: the utility model has the advantages of simple structure and reasonable design, convenient to use, the mode that can utilize the match grinding packing ring reduces the processing degree of difficulty of slewing bearing in process of production to after the wearing and tearing take place at slewing bearing's interior outer lane, compensate the problem that slewing bearing play increases through further abrasive machining to the packing ring, prolonged slewing bearing's life.
