The large bevel gear is fastened to the eccentric turntable by screws and elastic cylindrical pins. The eccentric turntable shaft is supported by two single row tapered roller bearings, so that the radial force of the large bevel gear falls between the two bearings with larger span. Improves the force of the shaft and improves the installation accuracy. The small bevel gear shaft is a single component, which consists of a small bevel gear shaft, three disc bearings, bearing sleeves, bearing shells, floating seals, etc. A total of 22 parts are connected by 10 M12×25 bolts, and the box The body is connected by 8 M16×48 bolts. Only 8 M16×48 bolts can be unscrewed during maintenance and dismantling, and the small bevel gear shaft system (excluding the outer ring of the cylindrical roller bearing) can be removed. It is easy to disassemble and adjust, and the small bevel gear shaft design has three adjustment rings, and the three links are relatively independent to adjust the gap between the bevel gear pair, the bearing and the floating seal. That is, the small bevel gear shaft system has been adjusted as a separate component for the bearing clearance and the floating seal clearance. Finally, when assembling the casing, it is only necessary to adjust the circumferential side clearance of the gear pair. The other bevel gear reducer small bevel gear shaft is a decentralized structure, which is very troublesome to adjust, and it is impossible to take care of the three links at the same time. There are always one or two links in a non-optimal condition, so the structure reduces the installation. Adjusting the time, improving the work efficiency, and more importantly, the components can be in the best working condition, thereby improving the assembly precision of the reducer.
The large bevel gear shaft system is the same as the small bevel gear shaft system. The adjustment links are relatively independent. They are also separate components, including 15 parts including eccentric turntable, large bevel gear, two-disc bearing and bearing sleeve. When repairing and dismantling, just unscrew the 8 M16×40 bolts on the outer ring of the end cover, that is, separate from the box, then unscrew the 8 M16×40 bolts in the inner ring and remove the end cover. The large bevel gear shaft system can be removed from The upper part of the reducer is completely removed, which brings great convenience for maintenance and repair. A new tapered gear tooth system and a reliable sealing structure are selected.
