The use of tire balancing machine:
Fill the tire to the proper air pressure and remove the lead from the rim.
Install the balance shaft with the tire mounting surface facing inward, select the appropriate vertebral body, and lock the tire with the locking device.
Turn on the balancing machine power, pull out the ruler to measure the distance between the rim and the balancing machine, the rim width, and the rim diameter, and input the measured data in turn.
Press the Start button, the balancing machine starts to drive the tire rotation, and the measurement begins.
Balancing machine measurement data automatically stop.
Rotate the tire until the light on one side of the balancing machine is fully lit, and knock in the corresponding gram of lead at the higher point of the rim on the fully lit side, that is, at 12 o 'clock, as well as on the other side.
Repeat the steps after 4 until the balancing machine is displayed as 0 (below 5 grams can be, because there is no lead block below 5 grams, the balancing machine does not show the unbalance below 5 grams).
Remove the tire at the end of dynamic balancing.
Dynamic balance: the wheels of the car are composed of tires and wheels as a whole. However, due to manufacturing reasons, the mass distribution of all parts of the whole cannot be very uniform. When the car wheel rotates at high speed, it will form a dynamic imbalance, resulting in the phenomenon of wheel shaking and steering wheel vibration in the vehicle. In order to avoid this phenomenon or eliminate this phenomenon that has occurred, it is necessary to make the wheel adjust the balance of each edge part by increasing the counterweight in the dynamic situation. This correction process is often referred to as dynamic balancing.
What is the principle of tire balancing machine
Here we first talk about the working principle of the tire dynamic balancing machine
Many repair masters in the repair process, often use a device, which is the tire dynamic balancing machine, many masters is to know the use, but the working principle is not understand, today I simply give you the master science.
Ordinary vehicles are overbalanced when they leave the factory, and the tires mutate for various reasons after they leave the factory. Generally manifested in the direction of the disc vibration, cab jumping, which is caused by the tire circular, in this case, it is necessary to move the balance check.
Under normal circumstances, in the rotating state of the rotor, the phase and size of the unbalance of the rotor are detected, and the weight is increased or removed by artificial or auxiliary devices in the corresponding position, so as to improve the mass distribution of the rotor relative to the axis, and achieve the purpose of dynamic balance of the rotor, which is the basic principle of the dynamic balance machine.
The dynamic balancing machine mainly detects the phase and size of the unbalance of the rotor, and some dynamic balancing machines (such as automatic balancing machines) are equipped with auxiliary devices for the weight and weight removal of the rotor.
Dynamic balancing machine how to carry out rotor dynamic balance detection
Dynamic balancing machine is a typical mechanical and electrical integration equipment, which can be divided into the mechanical body, the drive part and the transmission part, the signal acquisition part, the central processing unit, and each part performs its duties and coordinates with each other.
The mechanical body is mainly divided into three parts: the bed, the pendulum frame and the headbox, which are used for the support of the rotor. Different weights and specifications of the rotor need to choose the corresponding configuration of the mechanical body to ensure the accuracy of the rotor dynamic balance and the safety of the operator. The driving part provides the power for the rotor to rotate, and the driving part refers to the process shaft and belt transmission fixed device required for the rotor to rotate.
The signal acquisition part is used for the collection and preliminary processing of the rotor vibration signal, divided into speed acquisition and centrifugal force mining, balancing machine must first measure the speed of the workpiece, in order to determine the size of the centrifugal force, when the rotor is rotating, it will cause the vibration of the mechanical part, the sensor will collect the vibration signal, after a certain processing to the central processing unit.
The central processing unit is mainly divided into motherboard, filter board, A/D acquisition card, passive baseboard, which is used for the conversion, screening and calculation of rotor vibration signals, so as to obtain the phase and size of the rotor unbalance, and then displayed on the computer screen.
Performance index of dynamic balancing machine
Smaller attainable residual unbalance and unbalance reduction rate are the main performance parameters of dynamic balancing machine. The smaller reachable residual unbalance is the smaller unbalance of the rotor residual after dynamic balancing treatment, which is the embodiment of the accuracy of the dynamic balancing machine; The unbalance reduction rate is the ratio of the unbalance and the initial unbalance after a balance, which is the embodiment of the balance efficiency of the dynamic balancing machine. When we buy a dynamic balancing machine, these two performance indicators need to be considered. The dynamic balancing machine is used for the dynamic balance detection of the rotor, which can effectively improve the quality of the rotor and mechanical equipment, and is an indispensable instrument for many manufacturers. With sufficient understanding, in order to better do the dynamic balance.
How to adjust the car tire balancing machine
The use of automobile tire balancing machine:
1, Fill the tire to the appropriate air pressure, remove the lead on the rim, remove the stone in the tire pattern trench, and clean the rim;
2, Install the tire mounting surface inward on the balance shaft, select the appropriate vertebral body, and lock the tire with the locking device, (the vertebral body must be align the center hole. Otherwise, the data may be inaccurate.
3, Open the balancing machine power, pull out the ruler to measure the distance between the rim and the balancing machine, the rim width, the rim diameter, and in turn input the measured data;
4,Press the start button, the balancing machine begins to drive the tire rotation, the measurement begins, pay attention not to stand near the tire, so as not to happen danger;
5, Balancing machine measurement data automatically stop;
6, Rotate the tire to the side of the balancing machine position light is fully lit (different models display different ways) in the fully lit side of the rim more the high point is the position of 12 o 'clock to knock in the corresponding number of grams of lead, the other side is also the same;
7, Repeat the steps after 4 until the balancing machine is displayed as 0 (below 5 grams, because there is no lead block below 5 grams, the balancing machine does not show the unbalance below 5 grams);
8, Finish dynamic balance, take off the tire.
