JQ type clamp coupling

product category: Product display>> Rigid coupling
When the JQ type clamp shell coupling works, it mainly uses two clamp shells split along the axial direction, which are clamped by bolts to realize the two-axis connection, and the torque is transmitted by the friction between the two halves of the coupling surface. Use flat keys for auxiliary connection.

  Summary:When the JQ type clamp shell coupling works, it mainly uses two clamp shells split along the axial direction, which are clamped by bolts to realize the two-axis connection, and the torque is transmitted by the friction between the two halves of the coupling surface.

　　Working principle of JQ type clamp coupling

　　When the JQ type clamp shell coupling works, it mainly uses two clamp shells split along the axial direction, which are clamped by bolts to realize the two-axis connection. The torque is transmitted by the friction between the two halves of the coupling surface. Use flat keys for auxiliary connection.This product is used for the connection of the stirring shaft of the reactor that is too long, and the two stirring shafts are manufactured in two stages. If the output shaft of the vertical reducer is connected with the stirring shaft of the reactor, the jacket coupling should be mentioned when ordering. Non-standard requirements for output shaft size.

　　Advantages and disadvantages of JQ type clamp coupling

　　Advantages: 1. It consists of two clamp shells sectioned along the axial direction, mainly single-slot and double-slot, with keyway and without keyway, single-slot clamping rigid coupling with single bore and double bore The device is tightly sleeved on the shaft to provide high-torque grip without damaging the shaft surface. 2. The double-slot rigid coupling is convenient for disassembly and maintenance, and there is no need to move other parts. 3. The screws of the double-slot rigid coupling are installed positively and negatively, which can maintain dynamic balance. 4. The raw materials are aluminum, carbon steel and stainless steel. There are many models and specifications. It can also be customized according to the special requirements of customers.

　　Disadvantages: 1. The accuracy of the two-axis axis is low, the structure and shape are more complicated, and the manufacturing and balance accuracy is low. It is only suitable for occasions with low speed and stable load. 2. Generally, the linear velocity of the outer edge is not more than 5m/s. When the linear velocity exceeds 5m/s, a balance check is required. 3. The shaft does not need to move axially during assembly and disassembly, so the assembly and disassembly are very convenient. In order to improve the balance, the bolts should be installed in opposite directions. 4. The jacket coupling does not have axial, radial and angular compensation performance.
