  • Page 3 New principle for vibratory system – designed to reduce the effects of force relations The disadvantages of the former solutions are the considerable effects of force relations. As a result the plane separator circuit mostly had to form the difference between high measured values in the transducer planes in order to calculate the unbalances present in the correction planes.
  • Page 4 The dependence of the measured values L from distance ( a+b ) and R from distance ( a+b+c ) respectively becomes obvious from the straight lines in Fig. 1. They intersect the axis in the measuring planes. The forces in the measuring planes increase linearly with increasing distance.
  • Page 5 Another possibility to reduce the effects of force relations is an increased distance between measuring planes as illustrated in Fig. 3. This condition is not always feasible for lack of space and makes sense to a limited extent only because the left-hand measuring signal is reduced and consequently the influence from fluctuations of measured values will increase.
  • Page 6 Fig. 5 System with two virtual measuring planes outside of the physical range When the measuring planes are located in optimum positions, the virtual left-hand measuring plane is just inside the wheel disc when the wheel is as close as possible to the housing of the wheel balancer (see Fig.
  • Page 7 vibration. If forces are applied left of the node of vibration such as illustrated in Fig. 7b the vibratory system will respond in the direction of the forces applied. If, however, the forces are applied in the node of vibration as illustrated in Fig. 7c the vibratory system will maintain a state of rest.
  • Page 8 Fig. 8 Force measuring system with one virtual point of support In Fig. 9 two of the systems illustrated in Fig. 8 are arranged in series at different distances relative to the node of vibration. Consequently it is possible to establish a force measuring system for measurement of unbalances in two virtual measuring planes.

  • Page 11 In case of alternatives as shown in Fig. 11 and 12 , a centrifugal force introduced in S will be detected by transducer S' only as long as transducer M' does not supply any signal. Irrespective of the distance of the introduced centrifugal force transducer S' will always supply a signal proportional to the quantity of the centrifugal force.

  • Page 13 Hints for the field engineer Please provide machine model, serial number and program version number with problem reports. If there are unstable unbalance readings, insufficient plane separation or weight chasing prob- lems, in addition to the vibratory assembly consider the following causes: a) Does the wheel slip on the adaptor? Chalk mark adaptor and rim.

  • Page 14: The Vibratory Assemblies

    The Vibratory assemblies The vibratory assembly is the central module of a wheel balancer. It consists of the force guidance structure for directing the alternating unbalance forces via the transducers. The main shaft is supported on ball bearings in the vibratory tube with the wheel adaptor at the right-hand end.

    Nm). 15.2 Unbalance transducers and temperature sensor Two transducers ( Snap-on P/N EAA0260D59A, HOFMANN Mat-Nr. 6717253) and the accompanying temperature sensor are used with all variants of the Y2k vibratory assemblies. The alternating forces, produced during rotation of the unbalance, are converted into a proportional electrical charge utilising the piezo effect.

    The temperature sensor is fixed to the vibratory plate by a u-shaped spring ( Snap-on P/N EAS2025D12A, HOFMANN Mat-Nr. 1628090). Electrical connection to the Controller board is via the AWG 28 ribbon cable harness and connector X3.

    The pattern of a code strip, fixed to the circumference of the big pulley, is sensed optically by an encoder board positioned 1-mm above the pulley. The adhesive code strip (Snap-on P/N EAM0005D64A, HOFMANN Mat-Nr. 6419096) consists of a transparent foil with alternating black and white zones (32 increments) printed CAUTION! The wider zone of the zero reference has to be positioned to the edge of the pulley.

    The small pulley at the motor, the big pulley at the left end of main shaft and the Multirib belt ( Snap-on P/N 8-3531, HOFMANN Mat-Nr. 1252584) called mlti-vee belt as well. The screws fastening the motor to bracket are used for belt tensioning also.

  • Page 22: Belt Tension

    At reaching the pre-set speed, torque is cut back. The low torque is set to a rate, compensating the friction, for the most part, caused by the belt and by air drag of the wheel. Torque reduction is accomplished by lowering the voltage supplied to the motor with an AC controller, located on the Power Interface board.

    used as pivots for the shaft lock, if provided). Insert a big screwdriver between the upper and rear distance bolts. Lift the handle of the screwdriver in order to push the motor backwards and tighten the upper screw (10-mm width across flats). The initial tension of a new Multirib belt should be set to 200 N (Newton).

    15.5.1.2 Decelerating the main shaft by pressing the pedal With the BOXER S1100 and HOFMANN geodyna 930, a mechanical foot operated brake is used for decelerating the main shaft after measurement and as the shaft lock (see chapter 15.5.2.1).

    “C85” is diplayed. The user can use the plus and minus keys to select either C85 or C86. Pressing return causes the selected function to be executed and the machine to reset. C85 and C86 are used to synchronise the two flash chips. For a description see a Hofmann service manual.

  • Page 69: Weight Placement Modes

    2. Weight Placement Modes Figure 2. Weight placement positions 1 to 5. Nominal rim dimensions N1 to N3. The weight placement modes are described below. These modes are accessed by pressing the "weight" key. This cycles through the positions available. The order of the list is as follows; Normal, Alu1, Alu2, Alu3, Alu4, Hwm1, Hwm2, Static.

  • Page 70: Balancing Results Recalculation

    Weight Placement Quick Mode Holding down the weight placement key for 2 seconds results in a beep being generated and the weight placement selection mode being toggled between standard (the default) and quick mode. In quick mode the weight placement key cycles through NORMAL, HWM1 and HWM2 modes only. Upon machine power- on the selection mode active prior to power-down is restored.

  • Page 71: Manual Data Entry

    4. Manual Data Entry The nominal rim dimensions of the wheel can be entered by using the offset, width and diameter keys. These keys can be used when the balancer is idle. That is, there is no spin in progress and no other functions are in use.

  • Page 72: Weight Bar Operation

    5. Weight Bar Operation The weight bars indicate the direction required to rotate the wheel to bring the weight application position to the correct place for weight application. If there are no results displayed the bars rotate with the wheel (after encoder initialisation) but the green application led is never displayed.
  • Page 73 Non-HWM Sape Data Entry B9000/B9450 If the sape is held stationary for 1 second or more a beep is generated and the offset is shown in the left display panel. The value is removed from the display when the sape is returned to the home position. If a measuring run has been performed the results are recalculated and displayed when the sape is returned to the home position.
  • Page 74 Sape Weight Application When valid results become available in a hwm mode, the sape is configured for weight application. When the sape is now removed from the home position the sape position is checked against the stored offset positions. The sape arm is used to apply stick on weights only. If a stick on weight is required for a plane, the value of the weight is above the threshold and the wheel is rotated so that the green application led is lit for that plane, the machine will beep when the sape arm is moved to within +/- 1.5mm of the weight position.

  • Page 76: Wheel Spin Functionality

    8. Wheel Spin Functionality Common Features A wheel spin can be started when the machine is idle, when the star menu is active, when data is being entered manually and during user calibration, minimisation and some service codes. When the wheel spin starts the display is cleared of all data and a beep is generated.
