Splined Shafts and Splined Sleeves DIN ISO 14 – Description


图片1








General Description:Splined shafts with splined hubs are used when torques have to be transmitted and the component to be driven needs to be movable in axial direction.

Common Profiles:DIN5463/ ISO 14: Most common type,with straight, parallel flanks. This is the profile of catalogue goods. Other standards are less commonly used.

Profile Description DIN5463/ ISO 14: Number of splines x small diameter x big diameter. Example for a component with 6 splines and outside diameter 14 mm: splined shaft (KW) or splined sleeve (KN) 6 x 11 x 14.

Production Method: 

Cold drawn: Economical production method. Due to the chipless shaping, the shafts have a unsevered grain structure and thus a high strength. This production method is perfectly suited for easy to shape materials as C45, 42CrMo4 or SS304(1.4301).

  Milled: for single-unit production, if special dimensional accuracy is required or for high strength materials. With this methods, shafts with diameters (steps) that are larger than the    core diameter or outside diameter can be produced.


Splined Shafts

Profiles:Main dimensions in accordance with DIN5463/ ISO 14. Shaft with splines with parallel, straight flanks. Up to size 28 x 34 with six splines, from size 32 x 38 with 8 splines.

Materials:The catalogue splined shafts are cold drawn. The are optionally available in steel C45(1.0503), steel 42CrMo4 or stainless steel SS304(1.4301).

Tolerances:Straightness 0.8 mm/m, Torsion max. 0.5 mm/m. A straightness of 0.1mm/m can be produced on request.

Lengths:Splined shafts up to a length of 6 metres can be supplied fromstock. Standard lengths sold are 1 metre, 1.5 metre, 2 metres,3 metres and 6 metres. Price for customized lengths up to 6 metres on request.

Splined Sleeves 

Profile:Main dimensions in accordance with DIN 14. Hub with splines with parallel, straight flanks. Up to size 28 x 34 with six splines, from size 32 x 38 with 8 splines.

Materials:The catalogue splined hubs are optionally available in steel C45(1.0503), red brass or stainless steel SS304(1.4301).Other materials as e.g. 42CrMo4 on request.

  Tolerances:Profile inner diameter: H7. Profile outside diameter: H11. Outer dimensions: according to DIN 2768m.

Lengths:The standard lengths are equivalent to the maximum possible sweeping length. Longer splined hubs are available on request. Provide for at least one centred (or one-sided) relieve groove.
