Master Gears

Over three decades, TSA has been highlighted in the manufacturing of master gears, one of the most demanding control instruments in terms of dimensional tolerances and surface finishing requirements.

Applications Quality control on rolling gear testers of external spur/helical gears
Modules (DP) Normal module from 0.5 to 14.5 (Diametral Pitch from DP48 to DP1.75)
Profiles Standard involute, involute modifications
Tool size Max. width 100mm, min. external diameter 30mm, max. external diameter 300mm
Materials AISI O1 and SAE 8620 steels, Powder Metal (PM HSS); coated under request
Accuracy Up to DIN class 3
Bores Same as cutting tools; for specific tooling, please ask

TSA masters gears, manufactured under norm DIN 3970 or according to special designs, have gained recognition among customers worldwide. Each master gear is delivered along with a dimensional control report provided by the Metrology and Quality Department.

Spline gauges

For internal spline control, TSA manufactures go and no-go plug gauges up to class DIN 3. For external splines we offer ring gauges up to class DIN 5.
