Due to the size of these workpieces, how-ever, it was only possible to check quality-relevantfea
10、tures on these gears to a very limited extent.In addition to simple manual inspection devices, e.g.for the determination of the individual componenterror, or mechanically controlled inspection machinesfor the definition of profile and lead deviations, largegears were almost exclusively evaluated by
11、means ofa test run with definition of the contact pattern. Officialacceptance of large gears after a test run also re-mains obligatory today in many large companies.However, modern CNC-controlled systems are avail-able today, which allow individual parameters to bechecked on large gears, thus enabli

13、rolled gear inspection machines for smallergears have already been successfully used in theindustry for many years. Starting from the knownmeasuring tasks of profile, lead, pitch and runout oncylindrical gears, these machines offer a much greaterdiversity of application on the basis of their techno-
14、logy. Ultimately, an extended software package is allthat is required to inspect worms and wormgears,bevel gears or even gear cutting tools such as hobs,shaving and shaper cutters.Appropriate individual error inspection machines arealso available for workpieces up to 2600 mm (102“)outer diameter.Bas
15、ically, CNC-inspection machines consist of thefollowing components: Basic machine bed with rotational axis and linearmeasuring axes CNC-control for executing measuring movementsand forming measured value Evaluation computer system for programmingmeasuring runs and evaluating measurementresults, incl
16、uding documentation via printer Evaluation software for inspecting a diverse rangeof gear-related workpieces.Figure 1 shows an overall view of a CNC-controlledinspection machine for workpieces up to 2000 mmdiameter.Figure 01: CNC-controlled gear inspection machineThe components mentioned above can b
17、e easilyidentified. The functioning of a CNC machine is com-parable to the functioning of a mechanically con-trolled inspection machine for cylindrical gear meas-urement. The generating principle of an involute isused during profile measurement. Further parameterscan also be checked on cylindrical g
18、ears by the useof coordinate movements in one or more axis.In the case of a CNC-controlled inspection machine,instead of mechanical drive elements such as rollingdisks and friction bars electronically controlled indi-vidual drives are used on the axes. The functionalinterrelationship is shown in Fig
19、ure 2. The measuringmovement for generating the involute form occursthrough a coupled movement of rotational axis C,including workpiece with the linear axis X, and themounted probe system. The coupling ratio (transmis-sion ratio) depends on the technical data of the cylin-drical gear to be inspected

In addition, each axis isequipped with an M1/M2 drive motor as well as therelevant angle/length measuring system.2Figure 02: CNC-controlled profile measuring(principle)The synchronization of the movement cycle is en-sured by the CNC control. The probe system thusdirectly records the profile deviat
21、ions of the testpiece. Further representation and evaluation of themeasuring curves subsequently occurs via a PCcomputer. The inspection cycle for lead measurementon cylindrical gears is generally the same, except thatin this case a coupled measuring movement of axesC and Z (Figure 3) is executed in
22、 relation to the nomi-nal lead (base helix angle b). Depending on themeasuring task, diverse axial combinations can beimplemented, both for continuous and for individualpoint probing.Figure 03: Axes of a CNC-controlled gear inspectionmachine (example)2.1 Mechanical construction and probe systemThe b
23、asic component of an inspection machine is themachine bed, which should be designed as com-pactly and rigidly as possible, so that it can also ac-cept high workpiece weights without the overall ge-ometry being affected. Gray cast iron has provenitself as the construction material of choice, with rel
24、i-able achievement of these properties. Other materialsare also well proven.In the case of a workpiece loading above 10,000 kgin weight, as may occur with appropriate inspectionmachines, a stable bed structure alone is not suffi-cient, but a bond with a stable foundation must beproduced.
