DIN 5480 COUPLING

Product catalog summary

This technical document from ALGRA S.p.A. details specifications and product data for couplings and rotary tool holders compliant with DIN 5480 standard, used in machine tool applications. The document is structured into sections describing different types of couplings and tool holders, their configurations, cooling options, and technical parameters.

1. Overview and Standard

The products conform to DIN 5480, a standard for involute splined connections, ensuring compatibility and performance in power transmission applications. The document covers various coupling types and rotary tool holders designed for axial, radial, rear offset, offset axis, and angle adjustable configurations.

2. Product Types and Configurations

Axial Couplings (i = +1, 1:1 ratio): These include models with external coolant supply and both internal-external coolant supply. They are designed for collet chucks and shell end milling cutters. Key parameters include diameter (d1), spline size (ER), lengths (l1-l4), widths (b1, b2), heights (h1), torque (Nm), maximum speed (min-1), and power (kW).
Radial Couplings (i = -1, 1:1 ratio): These feature external and internal-external coolant supply options, designed for collet chucks and shell end milling cutters. They include detailed dimensional data and performance ratings.
Rear Offset Couplings (i = +1, 1:1 ratio and i = +0.25, 1:4 ratio): These couplings provide rear offset configurations with external or combined coolant supply, suitable for collet chucks.
Double Couplings (i = -1, 1:1 ratio): Designed for external coolant supply with collet chucks, these provide double coupling configurations.
Offset Axis Couplings (i = -2, 2:1 ratio): These are radial couplings with offset axis design, available with external coolant supply, for collet chucks and shell end milling cutters.
Angle Adjustable Couplings (i = +1, 1:1 ratio): These allow angular adjustment, with options for external or internal-external coolant supply, designed for collet chucks.

3. Cooling Options

Cooling is a critical feature for these couplings and tool holders, with options including:

External coolant supply - coolant is supplied externally to the tool holder.
Internal and external coolant supply - coolant is supplied both internally and externally for enhanced cooling performance.

4. Technical Parameters and Dimensions

The document provides detailed tables listing the following key parameters for each product code:

d1: Diameter of the coupling or tool holder.
ER: Spline size designation.
l1, l2, l3, l4: Various length dimensions defining the coupling geometry.
b1, b2: Width dimensions.
h1, h2, h3, h4, h5: Height dimensions relevant to mounting and clearance.
Nm: Rated torque capacity in Newton-meters.
min-1: Maximum rotational speed in revolutions per minute.
kW: Power rating in kilowatts.

These parameters are critical for selecting the appropriate coupling or tool holder based on machine requirements and operational conditions.

5. Gear Ratios and Transmission

The couplings are specified with gear ratios (i = n1:n2) such as +1 (1:1), +0.25 (1:4), -1 (1:1), -2 (2:1), indicating the transmission ratio between input and output shafts. This affects speed and torque transmission characteristics.

6. Product Coding and Ordering

Each product is identified by a unique code (e.g., RAPPS 20 221US3), which encodes size, configuration, and cooling type. The document includes ordering numbers and detailed dimensional data to facilitate precise selection and procurement.

7. Application and Usage Recommendations

The couplings and tool holders are designed for high-speed machining applications, with maximum speeds up to 24,000 min-1 and power ratings up to 25 kW depending on size and type. Proper selection according to torque, speed, and cooling requirements is essential for optimal performance and tool life.

Summary

This document serves as a comprehensive technical catalog for DIN 5480 compliant couplings and rotary tool holders by ALGRA S.p.A., providing detailed specifications, configurations, cooling options, and performance data. It is intended for engineers and procurement specialists in machine tool manufacturing and maintenance to ensure correct component selection for various machining setups.
