The balancing machine is a special measuring equipment, which serves to equalize the imbalance of the static and dynamic indicators of the rotating parts of the machines. The unit consists of one or a pair of supports where the products to be processed are placed, a rotary drive and an indicator measuring device. The information obtained as a result of processing allows us to identify the place and magnitude of the unbalance of the part.
Balancing machine: instruction manual
The following is a brief overview of the RAV models. Units are classified as automatic professional balancing devices. They are distinguished by ease of use and the presence of microprocessor control. After mounting the wheel and entering data about it, the protective cover closes and automatic rotation of the element begins, which continues until the necessary weight of the weight and its location are determined.
Among the causes of the imbalance, several main aspects are distinguished:
- Asymmetric distribution of materials.
- Violation of the arrangement of tires.
- Poor wheel alignment on the hub.
RAV balancing machine is designed to eliminate or minimize the malfunctions. The unit is suitable for all types of wheels of cars and cars and commercial vehicles (minibuses, minivans and others).
Preparation for work
Mount the device in the place of its subsequent operation. When installing, do not lift equipment by the shaft. The machine must be placed in a dry, closed and lit room on a flat, solid surface. In the end, you need to fix the unit using bolt fastening to the floor.
Then you need to do the following operations:
- Install and secure the shaft on the flange using a wrench.
- Fit the protective cover with the spring.
- Put an automatic device for measuring the width of the rim.
- Some modifications will require the installation of an electronic device for calculating radial beats.
- Connect the power according to the rules specified in the instructions.
- Connect pneumatic feed, if applicable.
Exploitation
Before installing the wheel on the shaft of the balancing machine, remove debris and foreign objects, as well as make sure the shaft and the center of the rim are clean.
Further manipulations are performed as follows:
- The cone that is most suitable for the workpiece is selected.
- The wheel is neatly placed to its fixed position on the support flange.
- The wheel rotates with the inner part of the rim towards the machine opposite the cone.
- The protective cap is mounted and secured.
- Some aluminum variations need to be mounted with a cone outside the wheel. The remaining operations are identical to the above methods.
Turning the unit on and off
The balancing machine is equipped with a main switch, which is located at the rear of the equipment. To activate the device, you must enter the program and turn on the system by moving the main toggle switch to the ON position. When carrying out this operation, do not get close to the rotating elements.
Wait for the time required to load the operating system. Then the first program page is displayed. Several options will be presented on the screen. The remaining functions of this technique are controlled by five keys located at the bottom of the monitor.
Civic balancing machine: description
Consider the features of the unit from this manufacturer of the "Standard" class. The model is equipped with an automatic lever of internal location, a modern liquid crystal display, an improved case. This design allows for comfortable access to the inside of the wheel, which is important when servicing alloy wheels. There is a wide protective casing and an extended overhang of the shaft. The accuracy of the installation is guaranteed by an electronic ruler; at the end of work, automatic braking is performed.
Among other features, one can note the direct measurement of corrective indicators, the start of an electric motor with the touch of a button or lowering the casing. It is possible to operate three operators without additional configuration of parameters. There is a split-installation system, a counter of machined wheels and protection against voltage surges. Thanks to the use of modern technologies, energy savings and reduced noise of the electric motor are guaranteed.
Calibration
Over time, the unit used begins to give not entirely accurate readings. Check its operation as follows:
- Take a wheel, for example, the 16th radius.
- Install it on the machine and enter the required parameters in manual mode.
- Activate the start button.
- After processing, the result is 25-30. We stuff the weights and run the unit back into operation. The result may be 05-10.
- If after the third launch the program asks to add one more load parameter, it is necessary to check the cones for the presence of backlash and their landing on the shaft.
If you have these problems, you will need to calibrate the balancing machines. This can be done as follows:
- After adjusting the program parameters to 00-00, fill in a 100 gram weight and start the machine. During normal operation, the parameters should become 00-100.
- You should think about calibration if there are differences of 5 units (for example, 05-95). You can still work on such an aggregate, but you will need to check the backlash and mounting.
- If the final value after starting the shaft with the control weight exceeds 15 units, an urgent calibration of the device is necessary.
- If the actions taken to set the parameters do not lead to parameters 00-100, you will need to carry out maintenance of the equipment, clean it of contamination, measure the mains voltage. Then recalibration is carried out.
Inaccuracies
The errors of the balancing machine and the possibilities for their elimination are given below:
- When starting up, the device generates an error and does not start the shaft - it is necessary to check the latch of the casing. If this does not help, clean the corresponding internal sensor from dirt.
- When you turn on the machine does not start - check the socket and switch. If necessary, replace the elements.
- Violation of the line. To check, it is necessary to install the stamped wheel and extend the measuring device. If discrepancies with the readings of the ruler are noticeable, they are calibrated according to the instructions.
- During operation, the device itself turns off - most likely, a microcrack appeared in the board. The item must be replaced.
Do it yourself
The following is a method of manufacturing a simple do-it-yourself balancing machine:
- A motorcycle wheel is mounted between a pair of identical racks. For the construction, wooden blocks, a brace, a segment of the brand, a central panel, a ball bearing and a socket for it, a support, a base, a fixing nut of a wing type will be required.
- The main racks are made of steel, a 32 mm semicircle is cut out in the upper part, where a ball bearing is mounted. It is insured by two plates with semicircular cutouts, fixed on three screws with nuts. The central panel is supported by a pair of braces.
The base is a five-millimeter steel sheet 30x50 cm screwed to wooden blocks (3x4 cm). The whole structure is fastened with T-sections with a length of 135 mm. The principle of operation is identical to the alignment of the wheels of bicycles.
