Aluminum alloy screw fixing type screw clamping type plum coupling

Structural features

1. Screw-fixed type: usually composed of two half-coupling bodies and screws for connection, and some products also have keyways. The half-coupling body is generally made of aluminum alloy. By machining the keyway on the shaft, the half-coupling is key-connected to the shaft, and then the two half-Couplings are fixed together with screws, thereby realizing the connection and transmission of the two shafts 3612.

2. Screw clamping type: mainly includes coupling body, elastic element and clamping screw. The body is mostly made of aluminum alloy, and common elastic elements are polyurethane plastic, diaphragm, etc. The elastic element and coupling body are tightly fixed by clamping screws to ensure reliable connection and transmit torque.

Performance characteristics:

High transmission efficiency , good adaptability , high rigidity and stability , low noise and low maintenance cost

Technical Parameters

1. Model specifications: There are various models, such as LK7-C32, SFC-060DA2, DBJ06-36, etc. Different models correspond to different parameters such as size, torque transmission capacity, etc.

2. Shaft hole size: The range of shaft holes is wide and can be selected according to different equipment requirements. Common shaft hole diameters range from a few millimeters to tens of millimeters. The shaft holes of some couplings can also be customized.

3. Allowable speed: generally between several thousand rpm and tens of thousands rpm. The specific value varies depending on factors such as model, size and material. For example, the allowable speed of DLB-20 clamping thread rotary coupling is 8000rpm, while the allowable speed of some high-precision diaphragm couplings can be as high as 10000rpm or even higher.

4. Allowable torque: The torque range is wide, ranging from a few Nm to hundreds of Nm, to meet the transmission requirements of various power equipment
