How do you cut external splines?

How do you cut external splines?

Tooth profiles of external splines can be cut by shaping, hobbing, form-milling, or power-skiving. The hobbing process typically offers the best balance between productivity and flexibility. However, due to sweepout clearances and tight part features, shaping methods are also commonly used.

What is spline cutting?

Spline cutting is the process of machining internal or external splines (ridges or teeth) onto shafts, gears and other mechanical power transmission components, which mesh with grooves in a mating piece allowing power to be transmitted from one to the other.

Can Moser axles be shortened?

All popular bearing sizes and bolt pattern combinations are available. If your future plans call for a narrower rear, Moser Custom Alloy Axles can be shortened and resplined to fit your needs and bolt pattern changes can also be made.

How do you shorten an axle shaft?

The only other way shorten some axles is: -Cut the axle just inboard of the bearing and seal diameter. -Ream a hole into the end of the axle under where the bearings sit. -Turn the other end of the axle down to fit into the hole you reamed with as much shrink fit as you think you can get away with.

How are internal splines cut?

The splines are cut into the shaft by a process called straddle milling. The indexing fixture holds the shaft of the spline steady while a groove is cut by the rotating milling cutters along its length. Depending on the depth of the spline, multiple passes along the same groove may be needed.

How are shaft splines made?

How much torque can 31 spline axles handle?

“This will give you a figure that represents the maximum amount of torque transmitted to both axles if you launched at your engine’s torque peak and dead-hooked out of the hole. A 30-spline axle is rated at 6,200 lb-ft, a 31-spline at 7,000, a 33-spline at 8,200, a 35-spline at 9,600, and a 40-spline at 12,000.

How are splines cut?

Splines can be either external or internal, and they may comprise a variety of tooth shapes to serve various functions. Tooth profiles of external splines can be cut by shaping, hobbing, form-milling, or power-skiving. The hobbing process typically offers the best balance between productivity and flexibility.

What is a spline?

What is a spline? A spline is any shaft that features a series of teeth that match spaces of a corresponding shaft. By mating an internal spline with an external spline, rotational movement and force is transferred along the same axis with performance dictated by the designed form and fit.

How do you use internal Spline tools?

Internal Spline Tools. A milling cutter can take the exact conjugate form of the spline tooth space. By using this type of tool, a spline can be made one tooth space at a time, successively indexing from space to space. The shaping process offers balance between flexibility and productivity.

What are the two pitches of a spline?

The two pitches refer to the tooth’s width and height respectively (a spline tooth is wider than it is tall). Common tooth profiles are “twice as wide as they are tall.” The most common pressure angle is 30°. An involute spline can be designed as a major diameter fit or side fit, achieved by varying the depth of the hobbing cut.
