Wheel Balancer Model Selection

Due to the diversification of rotating machinery, vibration, noise problems, mechanical life requirements are increasingly stringent, must be selected for different rotating parts suitable for the respective characteristics of dynamic balancing machine, and the corresponding correction of the imbalance, the following simple introduces how to select models.

Step 1: Select the dynamic wheel balancer, the first based on the shape characteristics of the rotating work piece, select horizontal or vertical wheel balancing machines, of course, if you have special requirements can also be manufactured in accordance with the actual needs of the design.

Horizontal wheel balancing machines ---- the balance of the rotor rotation axis was horizontal wheel balancer, in general, with the axis of the rotor of the shaft or assembly process, such as the motor rotor, machine tool spindles, rollers, fans, turbine, turbocharger rotor, horizontal wheel balancing machine.

Vertical Wheel balancing machine ---- is the rotation axis of the balance of the rotor on the wheel balancing machine was balanced in the vertical state machine, generally refers to the rotor itself does not have discoid workpiece shaft gear, a variety of automotive flywheel, clutch, pressure plate disk parts of the assembly, brake disc, brake drum, motorcycle clutch and magneto rotor, fan, fan, water pump impeller, pulley, wheel, etc., I produced the PHD series of vertical wheel balancing machines to meet specifications of the balance of the disc-type parts, vertical-sided wheel balancing machines series applies to the balancing of the workpiece itself does not have the shaft of the drum-shaped parts, such as car wheels, rims, centrifuge drum

Step 2: According to the rotor drive form the ring belt drive wheel balancing machine or gimbals balance machine or self-drive wheel balancing machines, wheel balancing machines drag rotor transmission mode ring with drag drag coupling and self- driver.

Circle with drag ---- rubber ring with or silk ring with the drag of the rotor by the motor pulley, so the lap belt to drag the rotor surface must be smooth cylindrical surface, and advantage of the lap belt drag does not affect the rotor unbalance, high precision balance.

Coupling drag ---- gimbal balance machine spindle and rotor link. The characteristics of the coupling drag is suitable for the appearance of irregular rotor can transmit large torque, suitable for drag fans and other air resistance of the rotor, the coupling drag the shortcomings of coupling itself unbalance impact on the rotor (and therefore coupling before use to balance), will introduce interference would affect the balance of accuracy, in addition to the connection plate to accommodate different types of rotor.

Self-driven - is the use of the power of the rotor's own rotation. Since the drive is the minimum drag impact on balancing accuracy, balance accuracy is up to the highest, but only structure allows special rotor in order to use this drag way.

The third step: According to the size of the selection of the work piece, such as the characteristic parameters of the type of work piece, diameter, length and weight, speed, select the sizes of dynamic wheel balancing machines, such as 5, 16, 50,160 type numbers indicate the maximum work piece quality, generally selected digital 1 / 3-2 / 3 of the balancing effect, the maximum or minimum can be done, but may not be able to meet the precision of the work piece.
