A horizontal dynamic balancing machine refers to a balancing machine that is horizontally placed on the balancing machine by the axis of rotation of the balancing rotor. The horizontal dynamic balance machine detection principle is basically the same as that of the general vertical dynamic balance machine. There are also soft support and hard support. Generally speaking, the rotor has a rotating shaft or a process shaft, such as a motor rotor, a machine tool spindle, and a drum. Fans, steam turbines, supercharger rotors, etc. are all suitable for horizontal balancing machines. Calibration can be done using a feeding method. The following is a brief introduction to the knowledge of the lower horizontal balancing machine.
All the rotors on the machinery and equipment used in the manufacturing industry rotate around its axis, precisely because of the uneven distribution of the mass distribution with respect to the axis, which causes centrifugal force. This type of unbalanced centrifugal force causes vibrations in the rotor bearings, which in turn causes noise and accelerates the loss of the bearing, which seriously jeopardizes the characteristics and service life of the product. Rotating parts such as motor rotors, machine tool spindles, internal combustion engine crankshafts, turbine rotors, gyro rotors and watch balances are subject to dynamic balance correction during the manufacturing process to operate smoothly and normally. Therefore, the horizontal dynamic balancing machine can play a perfect role. The dynamic balancing machine can not only complete the problems caused by the work, but also the production quality is excellent, stable and reliable, and the price is low, which leads to the horizontal dynamic balancing machine gaining many domestic and foreign Customer trust and support.
The horizontal dynamic balancing machine uses a rubber ring belt or a wire-woven endless belt, and the rotor is driven by the motor pulley. For this ring belt, the rotor surface layer must have a smooth cylindrical surface layer. The advantage of the belt belt is that it does not harm the rotor imbalance. The balance accuracy is high.
Correcting the imbalance of the rotor according to the data detected by the dynamic balancing machine can improve the mass distribution of the rotor relative to the shaft, and cause the vibration caused by the rotor during the rotation, that is, the vibration force acting on the bearing, thereby lowering to the allowable standard. Therefore, the horizontal dynamic balancing machine is an indispensable measuring instrument for reducing vibration, improving product characteristics and improving quality.
In general, the dynamic balance of the rotor contains two steps of detecting and correcting the amount of imbalance. The horizontal balancing machine is suitable for detecting the amount of imbalance. The correction of the unbalance is usually done by drilling machine, milling machine and other auxiliary equipment (such as spot welding machine) or manually. The dynamic balancing machine calibration device has become part of the dynamic balancing machine.
