Definitions
- the invention relates to a method and a device for recording and evaluating measurement data of a gearbox testing or measuring device, in particular for measuring the backlash of gearwheels.
- Modern gearboxes are subject to high requirements with regard to load capacity, service life and noise behavior, among other things. posed. For this reason, it is important to subject the gearbox manufacturing or assembly process to constant control and inspection in order to keep deviations and tolerances as low as possible and thus to ensure the required quality.
- the static measurement method does not meet these requirements. Therefore dynamic measuring methods are used for high quality requirements. A large number of measured values are recorded during the revolutions of the gearwheels, each tooth is measured against every possible tooth. If there is no 1: 1 gear ratio, a large number of revolutions are required.
- the object of the present invention is to provide a method for acquiring the measurement data of a dynamic test of the backlash of gears. It is also the object of the invention to provide a device for carrying out this method.
- the main advantage of the invention is to be seen in the fact that the detection of rotary encoder signals on the drive shaft and on the output shaft and their electronic further processing make it possible, when the drive shaft is forced to rotate, for the angular deviation of the output shaft to the drive shaft at any time and for every gear-tooth pairing for the dynamic testing of the backlash with the high accuracy desired in modern gearboxes.
- the angular deviations of the opposing tooth flanks can also be detected by reversing the direction of rotation, whereby a determination of the tooth flank play is possible.
- the encoder signals are digitized and stored in a data buffer, which makes them easily accessible for further processing and the measured values can be recorded independently of the cycle of a further evaluation unit.
- the deletion of the data buffer prevents errors in the measured value acquisition from occurring during subsequent measurement runs, so that this error remains undetected.
- the PROFIBUS is a manufacturer-independent, open fieldbus according to the international standard EN 50170. It is advantageous that when connecting sensors via fieldbus systems, the cabling effort and the number of lines between the measuring device and the subsequent electronics are minimized.
- the electrical properties of the PROFIBUS-DP correspond to the RS-485 standard, so it is Extensions or additions can be carried out particularly easily, for example using other computer systems as evaluation units.
- Continuous measurement series can be formed from the transferred contents of the data buffer, which simplifies a clear assignment of the individual values to the individual measurement positions for later evaluation in the case of a large number of transferred data buffers.
- Evaluation unit is subtracted or displayed visually, in particular as a continuous curve. This enables a simple control, or an overall view, of the range of fluctuation or the uniformity of the rotation imposed by the drive train on the drive train. This means that even non-specially trained personnel can easily be checked.
- this named embodiment variant can also be carried out in the opposite direction of rotation, which makes it possible to calculate a real tooth flank backlash from the difference from the data sets obtained for both directions of rotation, which provides information about the dynamic tooth flank backlash.
- the gearbox can be evaluated quickly and safely.
- the data obtained can be archived for later retrieval for complaint or control purposes, which in such cases allows a quick and simple statement about the quality of the delivered gear.
- the data obtained affect the assembly system itself. It is advantageous here that by comparing this data with the measurement results of the measurement of the gear housing or the gearwheels before assembly to the finished drives, an optimization of the assembly system and the assembly process with regard to the achievable tolerances and thus the quality is possible.
- the object of the invention is also independent of this by a device for recording and evaluating measurement data of a transmission test or measurement device, in particular for measuring the backlash of gear gears, an input shaft and an output shaft being arranged on the drive on the gear unit to be measured - And on the output shaft a rotary encoder for detecting the angular position is arranged, which scans the current position of a shaft at predetermined times and delivers a signal corresponding to this position and the outputs of the two rotary encoders are connected to a detection unit.
- the advantage here is that it makes it possible to determine the angular deviation of the output shaft to the drive shaft at any time and for each gear position, thereby making it possible to dynamically check the backlash with the high accuracy desired in modern gearboxes.
- the outputs of the data buffer are connected to a data transmission interface, in particular a Profibus-DP interface. place, connected.
- a data transmission interface in particular a Profibus-DP interface. place, connected.
- the Profibus-DP itself offers the advantages of simple cabling and standardized electrical properties. This helps to reduce costs and offers the possibility of easy integration into the other parts of the system.
- the type of data transmission interface should not be limited to a Profibus-DP, but other bus systems that meet the electrical and speed requirements can also be used.

- the rotary encoders 5, 6 deliver absolute values of the angular position of the drive shaft 3, or of the output shaft 4, but can also be designed as incremental encoders that deliver pulse signals, the frequency of which depends on the set speed of the gear 7 to be tested and the angular resolution of the one used encoders
- the rotary encoder 5 arranged on the drive shaft 3 scans the values for the current angular position of the shaft. These signals can be, for example, photoelectric, magnetic, optical or purely electrical in nature. Exactly such values are felt by the
- Output shaft 4 arranged second encoder 6. Both values are recorded by the recording units 1 and 2 at predetermined times and are available for further use.
- a preliminary measurement 21 begins after waiting for an adjustable running-in time 20.
- the unit is driven at a predetermined speed n.
- the zero crossing evaluation is carried out analogously to step 22.
- step 24 these two values are written into a data buffer, for example containing 2 times 50 values, and the counter i is increased by 1.
- steps 22 and 23 are continued. If it does, the content of the buffer is passed on to a further evaluation unit via a data bus, in particular via a Profibus-DP network, the counter i and the buffer are deleted. In the evaluation unit, two consecutive measurement series X j and Y j are formed from these different, for example 2 times 50 value data blocks X; and Y ;.
- Step 27 checks whether the flow measurement or the return measurement has just been carried out.
- step 29 forwards to steps 22 and 23.
- step 30 If the flow measurement has ended, the direction of rotation is reversed in step 30 and the return measurement 32 is started after waiting for the run-in time 31.
- Steps 22 to 26 are carried out analogously to the preliminary measurement, but step 27 passes on to step 33.
- step 34 leads back to steps 22 and 23.
