| Parameter | Formula (external spline) | |-----------|----------------------------| | Tip diameter (external) d_ae | d_ref + 2*m | | Root diameter (external) d_fe | d_ref - 2*m | | Tip diameter (internal) d_ai | d_ref - 2*m (approx – check table) | | Root diameter (internal) d_fi | d_ref + 2*m |

). If the PDF lists a different pitch diameter, the document is flawed. Step 3: Identify the Revision Date

Unlike other spline standards that vary the pitch diameter based on the number of teeth, DIN 5480 uses a philosophy. This design choice ensures that standard tools (like hobs and broaches) can be used across a wider variety of tooth combinations. Key Characteristics Pressure Angle: Always 30∘30 raised to the composed with power Module (

This part defines the acceptance testing procedures for splines. It provides the necessary formulas, guidance, and data to properly inspect splines manufactured according to DIN 5480. This ensures that parts meet the required quality standards. din 5480 spline dimensions pdf verified

Compare this to the older (often found in hydraulics).

Unlike other spline standards, DIN 5480 is based on . This design philosophy allows for easier pairing with standard roller bearings and significantly reduces the number of specialized tools required for manufacturing. Key Components of DIN 5480 Spline Specifications This design choice ensures that standard tools (like

The standard specifies the requirements for involute splines based on reference diameters. These splines are commonly used in mechanical engineering for connecting hubs and shafts, facilitating torque transmission in three ways:

(Root Diameter): The innermost diameter at the base of the tooth spaces.

To verify a DIN 5480 spline PDF, you must identify these core variables: 1. The Designation String This ensures that parts meet the required quality standards

The standard typically covers a module range of , a tooth count from 6 to 82 , and a fixed 30° pressure angle . For verified dimensions, engineers often refer to the multi-part series:

DIN 5480 distinguishes between actual tooth thickness (measured via pins) and effective tooth thickness (which accounts for geometric errors like pitch deviation and profile errors). A "Go" gauge verifies the effective size, while pins verify the actual size.

A critical aspect of working with DIN 5480 is understanding its current structure. The standard underwent a major revision to consolidate a sprawling series into a logical, manageable set of documents. The older standard, published in 1991, consisted of 16 separate parts (from DIN 5480-2 to DIN 5480-13), each covering basic dimensions and test dimensions for a single module size. This was found to have "structural and editorial weaknesses" and was streamlined.
