The literal industry meaning of splines is commonly referred to as ridges and teeth belonging to a drive shaft that connects with grooves on a surface and passes rotatory force or torque to that body. All the while it maintains an angular affinity with the mating piece. The connection between a mating piece and a spline is usually though meshing although there are other applications available where means of connections are unorthodox and contrary to the industry tradition.
The gear that you actually need to mount on a shaft could one of the two types; male or female. Another substitution of a spline is a thing called keyway and key that a custom Spline Shaft manufacturing services can extend to its’ customers. Although there are certain applications where keyway and key far surpass the usability of a spline, they are not very resistant to fatigue and nominal wear and tear while splines generally have a longer life and last longer.
The methods of manufacture of splines is one of the two methods and both of those methods depend on the type of spline. The two types are external and internal spline. In case of an external spline, their manufacturing usually involves broaching, rolling, milling, and extruding. Although these are only a few, a host of other methods exist for manufacturing external splines. For internal splines, the methods of manufacturing are a lot limited. Part of the reason for that is a lack of resource due to regulation and restrictions. For example, it is not possible to manufacture internal spline with hobbing due to no access.
In order to avoid stress concentrations on a shaft, we chamfer the ends of the splines we manufacture rather than leave abrupt ends that are prone to stress concentrations. This technique alone allows us to protect our manufactured shafts against design flaws and failure thus ensuring their durability that Ami Gears as a custom Spline Shaft manufacturing services can provide.
