In order to improve the rotation accuracy of wire rope twisting equipment, the cylinder should have high manufacturing and installation accuracy, otherwise vibration and additional load will be generated. As the main rotating support component of the machine body, the roller has a heavy task, not only to support the centrifugal force generated when the machine body rotates, but also to support a certain impact and vibration load. The diameter of the roller is much smaller than the diameter of the barrel, the relative speed is high (several times the machine speed), and the wear speed is fast. Therefore, there are strict requirements for the dimensional accuracy and shape tolerance of the roller in the processing process. The roller spacing should be adjusted regularly to maintain the coaxiality between the raceway of the body.
60%-70% of the total number of wire rope twisting equipment is the main equipment for the production of wire rope, of which the tube twisting machine accounts for a large proportion.
The body of the two-for-one twister is connected by several cylinders, and the rotation accuracy of the two-for-one twister body and the roller is an important condition to ensure the normal operation of the two-for-one twister. The I-wheel, creel and other wire passing elements shall be placed in the barrel of the tubular stranding machine. The barrel has a complex structure, large mass, and large moment of inertia during unbalanced movement, which requires high rotation accuracy of the machine body.
In order to improve the rotation accuracy of wire rope twisting equipment, the cylinder should have high manufacturing and installation accuracy, otherwise vibration and additional load will be generated. As the main rotating support component of the machine body, the roller has a heavy task, not only to support the centrifugal force generated when the machine body rotates, but also to support a certain impact and vibration load. The diameter of the roller is much smaller than the diameter of the barrel, the relative speed is high (several times the machine speed), and the wear speed is fast. Therefore, there are strict requirements for the dimensional accuracy and shape tolerance of the roller in the processing process. The roller spacing should be adjusted regularly to maintain the coaxiality between the raceway of the body.
The assembly of the barrel and idler of the wire rope twisting equipment is also an important link after the recovery of the rotation accuracy of the twisting machine, and the assembly process needs to be strictly implemented to ensure the assembly accuracy. After the wire rope twisting equipment has been running for a period of time, the relative position of the roller and the cylinder should be adjusted in time to maintain a high coaxiality between the raceway of the body and the output shaft of the main engine and eliminate the centrifugal inertia force.
In summary, the vibration of the wire rope twisting equipment body is due to the radial runout and circular runout caused by the coaxiality and roundness difference between the body raceways, which increases the centrifugal inertia force and causes the vibration of the body. To solve this problem, it is necessary to improve the geometric accuracy of the rotating body and the rotation accuracy of the roller, and take the corresponding technical measures such as cylinder and roller processing to improve the service life of the equipment.
