Spline Manufacturing UK

Splines transmit torque while locating mating components through multiple teeth around a shaft or bore. Ondrives supports spline manufacture as part of its wider precision gear and component capability.

Define the spline clearly

A production drawing should identify the governing standard or provide the full tooth geometry, including pitch or module system, pressure angle, tooth count, fit class, major/minor diameters and inspection method.

External and internal splines

Manufacturing method depends on whether the spline is external or internal, part size, material, hardness, quantity and accuracy. Ondrives' published shaping capability includes internal and external gear and spline work.

Inspection and fit

Spline inspection may use analytical measurement, span or pin methods, functional gauges or a combination depending on the specification. The intended fit and inspection method should be agreed before manufacture.

Use SplineCALC as an engineering aid

Ondrives SplineCALC can help review spline geometry and terminology. Final production data should always be checked against the drawing and governing standard.

Need help with a specific gear? Send Ondrives the drawing, model or available gear data. For new designs, include the operating duty and mating-component information so the manufacturing route can be reviewed in context.

Spline fit, geometry and inspection

Splines transmit torque while locating or allowing movement between shaft and hub. A usable specification must define the spline standard and fit system, not just the number of teeth.

Standard and designation

State the applicable standard and complete designation where available, for example DIN 5480 for involute splines. Preserve module, pressure angle, tooth count, reference diameter and tolerance/fit classes exactly.

Internal versus external

Internal splines can require shaping, skiving or another access-dependent process; external splines may be hobbed, shaped or ground depending on geometry and quality. Shoulders and tool run-out are important.

Fit and inspection

Effective fit depends on tooth thickness/space width, flank form, pitch, runout and datum relationship. Inspection method should match the standard, tolerance class and functional requirement.

SplineCALC is an engineering aid for geometry and designation work. Final production data should remain tied to the governing standard, drawing revision, material, heat treatment, engagement length and the mating member.
