High torque diaphragm type screw-on coupling

Structural features

1. Diaphragm design: It is usually composed of multiple diaphragms made of high-strength stainless steel sheets. These diaphragms can be in different shapes such as connecting rod type or whole piece type. Multiple diaphragms are stacked together and connected to the two half Couplings by bolts. They can withstand large bending deformation, thereby achieving high torque transmission.

2. Screw fixing method: Use high-strength screws to fix the diaphragm and the half coupling to form a stable connection structure, ensuring that there will be no loosening or relative displacement between the diaphragm and the half coupling during high torque transmission, ensuring the reliability of power transmission

3. Half-coupling structure: The half-coupling is generally made of high-quality metal materials with high strength and rigidity. The part connected to the shaft can be machined with keyways as needed to achieve close fit with the shaft and efficient torque transmission. At the same time, the design of the half-coupling also fully considers the connection method and force distribution with the diaphragm to ensure the stability of the entire coupling under high torque conditions.

Performance advantages : high torque transmission capacity , high-precision transmission , zero rotation clearance , good shock absorption performance , high rigidity and stability , automatic centering performance

Product Specifications

1. Torque range: The torque range of high-torque diaphragm screw-fixed diaphragm couplings of different models and specifications ranges from several thousand Nm to hundreds of thousands 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, dimensions, materials, balance level of the coupling, and the structure and number of diaphragms. In general, 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-load couplings is relatively low, but it can also meet the operating requirements of most industrial equipment.
