DIN 5462 Spline Standard PDF Guide

Introduction

DIN 5462 is a German national standard for splines, which are toothed wheels with a specific profile used for transmitting rotational motion and torque between two shafts. This standard defines the dimensions, tolerances, and requirements for splines used in various industries, including automotive, aerospace, and machinery.

Scope

This guide provides an overview of the DIN 5462 spline standard, including its scope, key dimensions, and technical requirements. It is intended for designers, engineers, and manufacturers who work with splines and need to ensure compliance with this standard.

Key Dimensions

The DIN 5462 standard specifies the following key dimensions for splines:

Module (m): The module is the ratio of the pitch diameter to the number of teeth. It is a fundamental parameter in determining the size and shape of the spline.
Number of Teeth (z): The number of teeth on the spline.
Pitch Diameter (d): The diameter of the circle that passes through the center of each tooth.
Tooth Thickness (s): The thickness of each tooth at the pitch diameter.
Tooth Height (h): The height of each tooth, measured from the root to the tip.

Spline Profiles

DIN 5462 defines two types of spline profiles:

Involute Spline: A spline with an involute tooth profile, which is a curve that is formed by the intersection of a circle and a line.
Straight Spline: A spline with a straight tooth profile.

Tolerances

The standard specifies tolerances for various dimensions, including:

Tooth thickness tolerance: The allowed variation in tooth thickness.
Pitch diameter tolerance: The allowed variation in pitch diameter.
Tooth height tolerance: The allowed variation in tooth height.

Material Requirements

The standard specifies requirements for materials used for splines, including:

Steel: The most common material used for splines, which can be heat-treated to achieve specific properties.
Other materials: Other materials, such as cast iron or non-ferrous alloys, may be used with the agreement of the manufacturer and customer.

Inspection and Testing

The standard requires that splines be inspected and tested to ensure compliance with the specified requirements. This includes:

Visual inspection: A visual examination of the spline for defects or irregularities.
Dimensional inspection: Measurement of key dimensions, such as tooth thickness and pitch diameter.
Material testing: Testing of material properties, such as hardness and tensile strength.

4. Centering Principle

Unlike involute splines (which center on the tooth flanks), DIN 5462 centers on the major diameter (d₁). This means:

The shaft's outside diameter and hub's inside diameter are machined precisely (h7/H7).
Tooth flanks transmit torque but have small radial clearance when unloaded.
Advantages: Simple manufacturing (broaching, milling).
Disadvantage: Lower torque capacity per size compared to involute splines.

2. Key Dimensions (Metric)

The standard specifies nominal sizes based on:

d₁ – Major diameter (centering diameter, h7 fit on shaft, H7 in hub)
d₂ – Minor diameter (root clearance)
b – Tooth width (nominal)
z – Number of teeth

Heavy Series

Application: High shock loads, heavy earthmoving equipment.
Characteristic: More splines (10 or more), shallow depth.
Example: N 10 x 52 x 60.

The "Exclusive" Data Point: One element often missing from free online calculators is the centering instruction. DIN 5462 requires manufacturers to explicitly state whether centering is on the major diameter (D), minor diameter (d), or flanks (b). The PDF standard contains the exact flowcharts for these designations.

Common size examples (excerpt from DIN 5462):

| Nominal size (d₁ x d₂) | z | b (mm) | d₁ (mm) | d₂ (mm) | |------------------------|----|--------|----------|----------| | 26 x 20 | 6 | 5.0 | 26 | 20 | | 32 x 26 | 6 | 6.0 | 32 | 26 | | 38 x 32 | 8 | 6.0 | 38 | 32 | | 46 x 38 | 8 | 7.0 | 46 | 38 | | 56 x 46 | 10 | 7.0 | 56 | 46 | | 65 x 52 | 10 | 9.0 | 65 | 52 | | 72 x 58 | 12 | 9.0 | 72 | 58 | | 82 x 68 | 12 | 11.0 | 82 | 68 | | 92 x 78 | 14 | 11.0 | 92 | 78 | | 102 x 85 | 14 | 13.0 | 102 | 85 | Application: General machinery, pumps, compressors

Note: The number of teeth varies with diameter – 6, 8, 10, 12, or 14.
