High rigidity diaphragm type double diaphragm coupling

Structural features

1. Double diaphragm design: The use of two diaphragms can provide higher torque transmission capacity and better displacement compensation effect than single diaphragm Couplings. The double diaphragms can bear and compensate radial, angular and axial deviations in different directions, so that the coupling can still maintain stable transmission performance under complex working conditions48.

2. Diaphragm material and performance: Diaphragms are usually made of high-strength stainless steel, such as 304 stainless steel, which has good corrosion resistance, elasticity and fatigue strength. This material can ensure that the diaphragm can withstand repeated deformation and is not easily damaged during long-term use, thereby ensuring the reliability and service life of the coupling.

3. Half-coupling with keyway: The half-coupling is machined with a keyway, which is connected to the shaft through the key to achieve effective torque transmission. The keyway is machined with high precision, which can ensure a close fit with the key, prevent looseness or relative sliding during transmission, and ensure the accuracy and stability of power transmission.

4. Screw fixing method: Use high-strength screws to fix the diaphragm and the half coupling together to form an integral transmission structure. The tightening torque of the screws is accurately calculated and strictly controlled to ensure that the connection between the diaphragm and the half coupling is reliable and at the same time, the diaphragm or the half coupling will not be deformed due to excessive tightening force, which will affect the performance of the coupling.

Performance advantages : high rigidity , high-precision transmission , good compensation ability , zero rotation clearance , high reliability

Product Specifications

1. Torque range: Different models and specifications of high-rigidity diaphragm double diaphragm with keyway screw fixed couplings have a torque range ranging from a few hundred Nm to tens of thousands of Nm. The torque value depends on factors such as the size, material, number and thickness of the diaphragms, and structural design of the coupling. Users can choose the appropriate model according to specific equipment requirements.

2. Aperture size: The aperture size is designed according to different application scenarios and equipment shaft diameters. Common apertures range from a few millimeters to hundreds of millimeters to meet the connection requirements of various shaft diameters and ensure a tight fit between the coupling and the equipment shaft.

3. Allowable speed: The allowable speed is relatively high, usually between thousands of revolutions per minute and tens of thousands of revolutions per minute. The specific speed depends on the specifications, size, material, balance level of the coupling, and the structure and number of diaphragms. Generally speaking, the allowable speed of small and precision couplings can reach 10,000-20,000r/min or more, while the allowable speed of large and heavy-duty couplings is relatively low, but it can also meet the operating requirements of most industrial equipment.
