Characteristics of flange coupling with the introduction

flange coupling is a coupling of the structure is very simple, mainly made up of two half-couplings and coupling bolts. Flange coupling coupling bushing holes before Assembly are the main processes of the boring, cutting and keyway trimming, coupling faces and other surface processing.

half coupling sleeve holes have tapered bore and cylindrical bore in two forms, than with a tapered bore cylindrical holes in process properties have more advantages. Coupling end face processing is often set on the shaft, this is in order to make the coupling on the end surface of the Tenon exactly wire concentric with the axis Centre, in this process, a special attention to ensure that the driving end surface and perpendicular to the axis of the rotor, and should pay attention to the dowel specification of interaction. Flange coupling without dowel, drill two half coupling should be set after the reaming process together.
cone-shaped bushing hole easy access between the mating parts of concentric, shaft coupling and a matching contact surfaces to achieve better co-ordination, testing is also more convenient, so using the tapered hole is common. Half coupling is usually made by forging, rough 2-3mm cushion on each side, and will conduct a stress-relieving heat treatment in order to make boring process. Coupling bores are usually performed on a lathe because the coupling sleeve Machining accuracy is very high, so the finishing holes usually grinding method.

coupling to the outer surface of the finishing in the same clamping in bore. Processed hole size hole and shaft surface contacts you need to check, for the mass production of couplings, tapered columns, which ensures the interchangeability of parts. Single piece production of coupling coupling sets on shaft end to testing. If the axis when noncompliance with holes, scraping holes coupling.
