A comprehensive overview of keyways, how they function, and the key and keyway dimensions/sizes involved in their design. Tables show the nominal shaft diameter range, key size, and dimensional specifications for the key and keyway (dimensions a through f) Keyways standard keyways and dimensions should be used whenever possible
Accepted standards are shown in machinery handbooks
Keyways should be dimensioned as shown in figures 1 and 2 to facilitate checking The tolerance limits for centering the keyway are just as essential as those limiting its depth and length. This document gives out key dimensions for metric and imperial sizes as per bs 4235 and bs 46 part 1 Key and keyway geometry, material selection, surface treatments, and tolerance specifications are all interconnected factors that influence the performance and longevity of the joint
Understanding these dimensions and their relationships is essential for designing and selecting appropriate keys and keyways in various applications. + keyways will be furnished per iso/r773 and js9 width tolerance unless otherwise specified (dimensions comply with din 6885/1) † requires use of chamfered keys. Key dimensions the inch and metric dimensions here correspond to common values
Detailed width tolerance information is best drawn from the manufacturer
Metric nominal dimensions, tolerances and gauging requirements bs iso 4156:2005_1 Keyways index keys and keyway dimensions keyways index This pa note will explain the uses of keys and keyways in pulleys and bushings, and present current industry standards for key and keyway component sizing. The table of size standards can also be found online in the small business size regulations set forth in the electronic code of federal regulations
Certain government programs, such as sba loan programs and contracting opportunities, are reserved for small businesses In order to qualify, businesses must satisfy sba's definition of a small business concern, along with the size standards for. If you don't want to go hunting it down, just click on the picture below and you can get the full size version. Specifying english keyways in the english system, it is standard practice to dimension keyways
Referencing figure 1, the keyway dimension is w x t1.
While a designer is free to specify any keyway they wish, straying from the standard option is likely to increase the cost, time, and complexity of the part Many keyways are milled directly into a shaft or broached into the corresponding bored holes. The key dimensions typically match the keyway size and can range from 1/8″ x 3/32″ to 1/4″ x 1/8″ It is important to ensure that the key and keyway dimensions match the motor and shaft sizes to ensure proper installation and operation.
Two pdfs with useful engineering data on keyway sizes and engineering limits and fits, just download A key is used on a shaft keyway to retain mechanical power transmission components such as gear drives and pulleys to transmit power The document provides standard dimensions for keys and keyways in both metric and imperial units
