General Information single flank gear roll inspection contact ratio > 1 roll contact ratio < 1 power gear flank analysing conventional with master gear The method of gear flank analysing is based on the single flank gear test. A specially designed roll master ensures a contact ratio of less than one. Thus the gears briefly loose contact in-between two adjacent teeth. As a result, the specimens’ deviations can be assigned precisely to the tooth number. The actual measurement takes place during the rolling process. The driving path is only a means of transportation and is irrelevant for the...

Measuring Tasks Position of axes Running quality Tooth Thickness Gear flank analysing with disc roll master Gear flank analysing with master Depending on the number of teeth and the device, the entire gear profile can be scanned within 3 to 13 minutes. It is possible to evaluate a large number of other parameters, besides the usual parameters, such as profile, pitch and runout, with the measuring time remaining the same. Gear flank analysing measuring allows an extensive and still efficient quality evaluation. The machines are designed for use in production and may replace the inspection in...

Gear flank analysing machines WSG use hedgehog roll masters. These are master gears with tooth segments that are adapted to the gear geometry to be measured. Due to the segments' vertical offset it is possible to evaluate the workpiece geometry in several planes. This ensures that the profiles of all tooth flanks are detected in several planes, which enables a calculation of the tooth traces. Hedgehog roll master Gear flank analyser with double spindle: cuts measuring time by half

Gear flank analysing is based on the principle of the single flank gear roll inspection and the roll master is adjusted to the gear profile to be inspected. Two rotations of the master complete the inspection of the set plane of the workpiece. Rotary axis A of the workpiece and rotary axis B of the roll master are electrically connected. Simultaneous movement of axis Z1 and axis Z2 enables measurements in as many planes as necessary. The tip centre distance and the position of the gear profile to be inspected are logged in the inspection plan and automatically controlled during the...

The latest version of the evaluation software supports various graphic charts and evaluations - including unique and basically new assessments for the completely detected tooth flanks. Standard evaluation of profile, helix (of four teeth), pitch and runout plus profile and helix of all teeth, detecting the worst tooth. All important values are clearly displayed in various charts. Quality control charts can be selected separately for all attributes depending on the processing machine. An overview of all evaluations is given.
