Coupling screws and adjusting coupling

　　1. The semi-detachable coupling of the coupling
　　One bushing is a clamping type, and the other bushing is a separate connection method.It is possible to connect the equipment only on the separate side with the clamping type-side connected to the shaft.
　　2. Keyway type of coupling
　　The same general connection method as the positioning screw fixed type, suitable for higher torque transmission.In order to avoid axial movement, it is used together with set screw fixed type, clamping type, etc.
　　3. The expansion sleeve type of the coupling
　　Utilizing the connection method of the expansion effect of the tapered bevel, a reliable and stable connection can be realized.Suitable for high-torque transmission, suitable for the spindle of the machine tool.
　　4. Coupling adapter + clamping type
　　Insert the adapter into the clamping type to make it suitable for the 1/10 tapered shaft type of the servo motor.
　　5. Set screw fixed type of coupling
　　Low cost, customary approach.However, since the front end of the screw directly touches the shaft, the shaft may be damaged or it may be difficult to disassemble.
　　6. Clamping type of coupling
　　The tightening force of the screw shrinks the shaft hole, thereby clamping the shaft.The equipment and assembly are easy and simple, and will not damage the shaft.
　　7. Separate type of coupling
　　The shaft hole can be cut.Therefore, the equipment and disassembly can be carried out easily without moving the equipment.Otherwise, it will not damage the shaft.
　　Hoisting parts coupling search is an important job in the equipment maintenance process. Although the principle is simple, it is very practical.The alignment methods often used on small pumps include single-meter method, double-meter method, and three-meter method, etc. No matter which method, they have a common feature; alignment in the horizontal plane is more prone to error and repeatability than in the vertical plane. Strong, time-consuming and cumbersome to calculate.
　　1. Fix the outer leg of the motor side of the lifting accessories coupling and move the inner leg until the eccentric line between the motor and the pump center is zero.To ensure that the motor does not move arbitrarily, after fixing the feet on one side of the motor, the other side should be supported with a jack wire.
　　2. Fix the inner feet of the coupling and move the outer feet to make the eccentricity of the two center lines zero.
　　3. After the above two methods are repeated several times, the coupling can be in a good alignment state.
