Car Repair Equipment Knowledge-Car Tire Balancing Machine

Different rotating work due to the increasingly stringent requirements of the diversification of the rotating machinery vibration problems, noise problems, mechanical life, you must choose the suitable for the respective characteristics of dynamic balancing machine, and a corresponding correction of the imbalance, the following simple how to choose the models introduced.

Step 1: Select the Wheel balancing machine, first select horizontal or vertical balancing machines according to the rotation of the workpiece shape characteristics, of course, if there are special requirements can also be manufactured in accordance with the actual needs of design.

Horizontal balancing machine ---- is the axis of rotation of the rotor to be balanced on the balancing machine horizontal state of the balancing machine, in general, having a rotating shaft or a rotor assembly process shaft, such as the motor rotor, spindle, drum, fan, turbine, turbocharger rotor are applicable to horizontal balancing machine.

Vertical balancing machine ---- is the axis of rotation of the rotor to be balanced on the balancing machine showed a balancing machine in the vertical state, generally refers to the rotor itself does not have a rotary shaft of the disc-shaped workpiece such as gears, various automotive flywheel, clutch, the pressure plate its assembly, clutch and magnetic rotor, fan blades, pump impeller, pulley, wheel disk brake disc, brake hub, motorcycle parts, I produced the PHD series vertical balancing machines to meet the needs of kinds of specifications of the balance of the disk parts, and vertical-sided balancing machine series apply to the workpiece itself does not have the dynamic balance of the shaft of the drum parts, such as car wheels, rims, centrifuge drum

Step 2: According to the form of the rotor drive select is a lap belt drive balancing machine or gimbal balancing machine or self-drive balancing machine, rotor balancing machine drag Transmission circle with drag coupling drag and drive.

Lap belt drag ---- is the use of a rubber annular belt or silk endless belt, drag rotor by the motor pulley, so the lap belt drag requirements of the surface of the rotor must have a smooth cylindrical surface, the lap belt drag advantage is not affected the amount of unbalance of the rotor, the high precision balance.

Coupling drag ---- gimbal link spindle and rotor balancing machine. Coupling drag characteristics is suitable for the outer rotor irregular, large torque can be passed, and suitable for pulling the blower windage larger rotor, coupling drag disadvantage is that the amount of unbalance of the coupling itself interested the rotor impact (and therefore coupling before use to be balanced), will introduce interference affect the balance of accuracy in order to adapt to the different models of the rotor, in addition to a large number of connections disk.

The self-driven ---- is the use of the momentum of the rotor itself is rotated. Self-driven drag minimal impact on balancing accuracy, balance accuracy up to the highest, but only special structure allows the rotor to use this drag.

Step 3: According to the characteristic parameters of the size of the selection of the workpiece, such as the type of a workpiece, an outer diameter, length and weight, speed, etc., to select the size of the wheel balancing machines models, such as 5,16,50,160 type, etc., the number represents the maximum workpiece quality, generally selected digital 1/3 to 2/3 of the dynamic balance better, maximum or minimum can be done, but may not be able to meet the precision of the workpiece.
