Standard spline

A standard spline is a spline shaft produced with the component rolling.
It fundamentally has a unique feature for all the usages compared with a past spline, and it has wide coverage as a spline shaft for the torque transmission.
Our company is having standard goods of various sizes of this spline on hand, and use this standard spline for the design and the product as well as the case to use a standard Migaki steel bar, please.
Standardization, the quality improvement of the design, and the effect of reduction in costs can be expected.

The axis spline: A basic size of large diameter (dk) and small diameter (dr) is assumed to be the maximum size.
The hole spline: A basic size of large diameter (Dk) is assumed to be a lower limit. To center it accurately with the broach tool guide part, small diameter (Dr) is assumed to be an allowance of HB.
A center match becomes tooth side match.
Hameai becomes sliding Hameai.

A dynamic, permissible torque was calculated as allowable shearing stress τα=400kg/cm2 in consideration of receiving the bending moment as a lengthy cargo, and being used for the location in addition, with the vibration.
The calling diameter can produce 25 or more up to 2000mm and the one that is longer than the length of the standard goods 1600mm be produced up to 3000mm with the condition. I will receiving an order produce SCM3 excluding a standard material. Partial of stick material Inquiry like form rolling, the short one, and the one etc. of involute tooth.
