Online balancing device and method for stranding machine

Abstract

The invention discloses an online balancing device and method for a stranding machine. The device comprises the stranding machine and a portable dynamic balancing instrument, wherein a flywheel disc is concentrically assembled on a main shaft to form a main shaft flywheel rotation mechanism; two main shaft flywheel rotation mechanisms are symmetrically installed at the two sides of a rocking backet, a first end of the main shaft is connected with one side of the rocking backet through a first bearing, a second end of the main shaft is installed on a main shaft seat in a penetrating manner andthrough a second bearing, and the main shaft seat is fixed to a main machine support; during balancing, a probe is fixed to the main machine support, a measurement point of the probe and the main shaft are located at the same height and the measurement point of the probe is aligned with the main shaft at one side, and a magnetic vibration sensing head is placed at the middle position of the frontside of the main shaft seat at the same side; the probe and the magnetic vibration sensing head are connected to a dynamic balancing display separately; and online balancing for the stranding machineis realized by configuring an arc-shaped counter-weight sheet with a corresponding angle at a corresponding angle on the flywheel disc at the same side according to a measurement result which is displayed by the dynamic balancing display when the running speeds of the main shaft and the flywheel reach a set value.

Description

technical field [0001] The invention belongs to the technical field of strand twisting machines, and in particular relates to an online balancing device and method for strand twisting machines. Background technique [0002] At present, in the daily maintenance process of our stranding equipment, according to the requirements of equipment precision standards, the vibration of stranding machine tools is controlled. The focus is on the part of the main shaft flywheel. It is required that the vibration of the torsion shaft at the working speed of the load: <3mm / s, to ensure the stranding The machine runs smoothly. Therefore, it is necessary to dynamically balance the flywheel of the stranding machine tool every month, disassemble the flywheel that does not meet the standard, send it to the designated place, use a fixed balancing machine to balance it, and then assemble it to ensure that the vibration of the equipment is up to standard during operation . At the same time, ac...

Problems solved by technology

[0003] The disadvantage of the existing technology is: at present, our company has more than thousands of stranding machines, and the amount of dismantling the flywheel is as high as 1300 times per month (calculated on a 12-month cycle)

According to the maintenance workload statistics, it takes an average of 50 minutes to disassemble and assemble the flywheel. Except for the transportation time, it only takes 1083 hours for disassembly and assembly per month, plus the work time for calibration and balance, the maintenance workload is very huge
