Loading Conditions - Metric dialog box

Specifies the influence of production and operating parameters to the connection acceptability.

Involute Splines.

In the Involute Spline Connection Generator, on the Calculation tab, click Loading Conditions.

Note: This dialog box is available only if you select the ISO or CSN spline type and Metric Method in the Strength Calculation area on the Calculation tab.

Joint type
Fixed	Joins splines firmly by pressing or fixed by rings avoiding axial movement.
Working Conditions
Specifies the type of working conditions.
Tooth Side
Specifies the type of tooth sides.

Recommended values of allowable pressures on tooth sides:

Type of loading		Working conditions	Hardened Tooth Side	Non-Hardened Tooth Side
Type of loading		Working conditions	Allowable pressure p_D[kg/mm3]
flexible	under load	adverse	-	0.3 - 1
		medium	-	0.5 - 1
		advantageous	-	1 - 2
	no load	adverse	1.5 - 2	2 - 3.5
		medium	2 - 3	3 - 6
		advantageous	2.5 - 4	4 - 7
fixed		adverse	3.5 - 5	4 - 7
		medium	6 - 10	10 - 14
		advantageous	8 - 12	12 - 20

Factor of Tooth Side Contact

The factor indicates the load is not spread evenly on all the spline teeth because of production and assembly inaccuracy. At a common and higher mounting accuracy, it is supposed that one half of teeth carry the load (K s = 0.5), for splining with higher production inaccuracy the load is only carried by one third of teeth (K s = 0.3).
