Reducer shaft assembly

Bearing diameter held with grinding allowance.

Stepped reducer input shafts on a measurement table

Project

Journal diameter held with grinding allowance.

Stepped reducer input shafts for a machinery OEM in Kocaeli. Concentricity, face, and keyway slot had to come from the same turning reference. Long shaft was not left to a second setup.

Requirement

Deflection was accumulating in the second setup.

When the shaft was re-clamped, the journal ran hot. If grinding allowance was left without a station, the next line step drifted. Keyway had to open without breaking the turning datum.

Kapsam

Diameter chain, allowance, and keyway note.

Scope was not a single shaft but a shaft group carrying the same allowance on spare batches.

Second support on long shaft to cut deflection.
Keyway note
Milling opens the slot without breaking the turning reference.
Grinding allowance
Allowance written on the job packet. Next line step stays in station.

Yaklaşım

Diameters written in a single chucking.

Shaft length called for a second setup. Live center engaged; keyway routed to mill with turning datum preserved on documentation.

Uygulama

Reducer recognized the shaft on spare batch too.

After first shaft measured, job card locked. Spare batch delivered same allowance and concentricity. Journal heat closed without second setup.
