High rigidity diaphragm type screw clamp coupling

Structural composition

1. Diaphragm: Usually made of high-strength stainless steel sheet, it has a variety of shapes, such as hexagonal, octagonal or whole piece. These diaphragms have good elasticity and toughness, and can effectively compensate for the displacement deviation between the two shafts while transmitting torque.

2. Half coupling: Generally made of high-quality carbon steel or alloy steel, it has high strength and rigidity. One end is processed with a hole and keyway that matches the shaft, which is used to connect with the shaft and transmit torque; the other end is tightly fixed to the diaphragm by screws to ensure the reliability and stability of the connection.

3. Screws: As the key components for fixing the diaphragm and the half coupling, high-strength bolts or screws are mostly used. Their quantity, specifications and distribution are determined according to the size of the coupling, torque requirements and other factors. The tightening torque must be strictly operated according to the specified value to ensure the connection between the diaphragm and the half coupling is tight and prevent loosening.

Performance characteristics : high rigidity , high-precision transmission , good compensation ability , zero rotation clearance , corrosion resistance

Product Specifications

1. Torque range: The torque range of high-rigidity diaphragm screw clamping diaphragm Couplings of different models and specifications ranges from a few hundred Newton meters to tens of thousands of Newton meters. The specific torque value depends on factors such as the size, material, number and thickness of the diaphragms, and structural design of the coupling.

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.

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. 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.
