High rigidity and high speed diaphragm type screw clamp coupling

Structural features

1. Diaphragm: Generally made of high-strength stainless steel sheet, with various shapes, such as 6-corner, 8-corner or whole piece. Multiple diaphragms are connected to the two halves of the coupling by screws, and each set of diaphragms is composed of several stacked pieces. This structure enables the diaphragm to produce elastic deformation while transmitting torque to compensate for the displacement deviation between the two shafts.

2. Half coupling: Made of high-strength metal materials, such as high-quality steel or aluminum alloy, it has high rigidity and strength and can withstand large torque and centrifugal force. The connection between the half coupling and the diaphragm is precisely machined to ensure the accuracy and reliability of the connection and ensure that the torque can be effectively transmitted from the driving shaft to the driven shaft.

3. Clamping screws: usually high-strength stainless steel screws, used to firmly clamp the diaphragm between the two coupling halves. The tightening torque of the screws is strictly calculated and controlled to ensure that the connection between the diaphragm and the half coupling is tight and reliable, preventing loosening during high-speed operation, thereby ensuring the performance and safety of the coupling.

Performance advantages : high rigidity , high speed adaptability , high-precision transmission , zero rotation clearance , good corrosion resistance , maintenance-free or low maintenance

Specifications :

1. Torque range: The torque range of Couplings of different models and specifications varies greatly, generally ranging from tens of Nm to tens of thousands of Nm. You can choose the appropriate model according to the specific equipment requirements. For example, the torque range of a small diaphragm coupling may be between 100-1000N.m, while the torque range of a large industrial diaphragm coupling can reach 5000-50000N.m or even higher136.

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. Generally speaking, the coupling aperture used in small equipment may be between 10-50mm, while large mechanical equipment may require a coupling with an aperture of 50-200mm or larger16.

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 and material of the coupling. Some precision high-rigidity and high-speed diaphragm couplings have an allowable speed of 10,000-20,000 r/min or more, which can meet the operating requirements of most high-speed equipment.
