It includes dimensional information for different shaft diameters, key sizes, keyway widths and depths. 303.377.3434 (fax) 877.868.2883 (toll free) Technical data for metric keys and keyways per iso/r773
Includes js9, p9, d10 tolerances, dimensions in mm & inches for couplings.
This guide will walk you through what a keyway is, why it matters, the different types, how sizing works, and provide you with a detailed keyway size chart in both metric and imperial standards. Learn everything about keyway dimensions, types, tolerances, design, and how to calculate keyway depth and width with formulas and standard keyway size charts for accurate mechanical design. A comprehensive overview of keyways, how they function, and the key and keyway dimensions/sizes involved in their design. This page provides a detailed keyway chart to help engineers select precise seal fits for transmission applications in industrial environments.
Surface finish — sides and bottom of keyways shall not exceed 250 micro inches See page 2 for optional p9 & d10 keyway dimensions. It is recommended that for detailed design the relevant bristish standard or a reputable reference text is used A fixed coupling is one which is an interference fit /close fitted or is guided
A flexible spline is one which permits small misalignments < 1 degree
Two pdfs with useful engineering data on keyway sizes and engineering limits and fits, just download Shaft keyways and keys are used to transmit torque from shafts to mechanical transmission elements such as gears, and pulleys, using a keyed joint They can be made using a standard stock material such as key stock or custom machined to suit the application. Bore, keyway & setscrew information.standard setscrew locations if one setscrew is furnished the location will be 0°
If two setscrews are furnished the locations will be 0° and 90°, unless otherwise specified. A list of the standard key sizes and corresponding keyways for metric shafts are listed below in table 2 The common specification dimension, key size, is highlighted. Metric keyway calculator key dimensions
Parallel keys are most commonly used
The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion. This document gives out key dimensions for metric and imperial sizes as per bs 4235 and bs 46 part 1 The document provides standard dimensions for keys and keyways in both metric and imperial units Tables show the nominal shaft diameter range, key size, and dimensional specifications for the key and keyway (dimensions a through f)
Keys can be either rectangular or square, and specifications cover shaft diameters from 10mm to 150mm in metric, and 1/4 to 6 in imperial units Metric and imperial keys and splines brief description of keys / keyways and splines keys and splines are mechanical components used in engineering to transmit torque and motion between rotating components, such as shafts and hubs.
