During tedious process of wheel manufacturing there are very high possibilities of run out. By the help of our Wheel Runout Gaging Solutions its just a matter few seconds to analyse the wheel for both lateral and axial runout. According to specified tolerances the part is either accepted or rejected. The machine meets or exceeds SAE Standard J2133-2001.
The Machine employs state of the art sensors and control technology to measure runouts of the light automotive wheels and carries out the marking of the low-point of the average radial runout. The low point marking is used for match-mounting tires on the wheels to minimize the mass-unbalance of the assembly.
The machine is divided in to four stations. Namely Waiting Station, Gaging Station, Rejection Station and Low-Point Marking Station. The wheels are placed on the waiting station for initiating the process. As soon as the gaging station becomes free, the wheel is moved forward to the gaging station for carrying out the measurements. The wheel is rotated at a constant speed and four high resolution linear gages are brought forward to conatct with wheel at the appropriate locations. These gages measure the values of inboard radial, outboard radial, inboard lateral and outboard lateral rououts as the wheel rotates. These measurement are then transferred to the control system where they are processed through a proprietry algorithm which carries out various compensations and extracts the final rounout values. It also computes magnitude and phase angle of the first harmonic of the average radial runout. All these reading are compared with their corresponding preset criteria and the decison regading the acceptance of the wheel is made.
The wheel is then moved ahead and, based on its runouts, is either rejected and removed from the main line, or moved to the next station, i.e., low-point marking station. The low-point is marked on the wheel at the location of the minimum of the first harmonic amplitude computed earlier. This mark is used by the automobile assemblers at the time of assembling tire and the wheel in order to minimize the amount of resulting mass-imbalance.
