HangzhouHigh-speed diaphragm coupling

high speedDiaphragm couplingThe structure makes the left and right centers of gravity close to the support bearings of the units on both sides to the greatest extent, and the additional bending moment to the rotor shaft head is small, which is conducive to high-speed and stable operation.

The design of the high-speed diaphragm coupling should be able to operate continuously in the unit for more than 3 years, and the coupling and shaft connection should be able to withstand 175% of the large continuous torque during the operation of the unit; when transmitting 175% of the moment specified by the buyer The coupling does not break when torque is applied, but the connection is allowed to fail; when the displacement of the axis of the two shafts connected by the coupling reaches 125% of the rated value, it can operate normally and continuously.For couplings with spacer sleeves, the spacer sleeve should have sufficient length so that the coupling can be assembled and disassembled without moving the shaft.The coupling hub and shaft should adopt an interference fit.The size of the interference can be proposed by the buyer, but it must be agreed by the seller.

特点

The shaft hole types of high-speed diaphragm couplings include cylindrical holes with keys and conical holes; cylindrical holes without keys and conical holes for hydraulic assembly.The type of shaft hole is selected by the buyer.The tolerance level of cylindricity of shaft hole joint surface is 6.When measuring the cylindricity tolerance, it should be done before the keyway machining.Choice of interference between shaft hole and shaft (recommended value): cylindrical shaft hole with key, the interference is 0.5%-0.75% of the shaft diameter; conical shaft hole with key, the interference is 1% of the shaft diameter; for cylindrical holes without keys, the interference is 1.5%-1.8% of the shaft diameter; for hydraulically assembled conical shaft holes, the interference is 1.8%-2.0% of the shaft diameter.
