shaft slot - Shaft Keys Definition Type and Application isi surat ad dhuha In mechanical engineering a key is a machine element used to connect a rotating machine element to a shaft The key prevents relative rotation between the two parts and may enable torque transmission For a key to function the shaft and rotating machine element must have a keyway and a keyseat which is a slot and pocket in which the key fits For a key to function properly both the shaft and rotating elements gear pulley and coupling must have a keyway and a keyseat Usually the term keyseat is referred as a groove or pocket on a shaft and a keyway is a slot in a hub in which the key fits into The complete system is called a keyed joint Figure 2 Figure 2 Difference Between Slot Holes Groove Keyway Basic Of Mechanical Shaft key keyway Key types Keyed Joint application benefits A keyed joint is used to ensure orientation or restrict rotational movement between parts as in the case of joining a shaft with a coupling To create a keyed joint a key is used that fits between slots manufactured into the two parts being joined The slot is defined as a keyway or a keyseat depending on the whether the slot is located on A precut slot is present in shaft in which one part of shaft key can fit and the other part of shaft key fit into a keyway which is a slot provided in the hub The overall system is known as keyed joint and is able to provide relative axial movement between two parts Shaft key can be made up of a number of materials most commonly from steel For a shaft key to function properly both the shaft and rotating elements gear pulley and coupling must have a keyway and a keyseat One part of the Shaft key fits into a precut slot in the shaft known slot gp as a key seat and the other part fits into a slot in the hub called a keyway The whole system is called a keyed joint Shaft key selection is crucial in avoiding premature failure on keyed joints 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 Shaft Keys 101 Machine Design Key engineering Wikipedia The keyway is a slot machined either on the shaft or in the hub to accommodate the key It is cut by a vertical or horizontal milling cutter A little consideration will show that the keyway cut into the shaft reduces the loadcarrying capacity of the shaft In mechanical engineering a key is a machine element used to connect a rotating machine element to a shaftThe key prevents relative rotation between the two parts and may enable torque transmission For a key to function the shaft and rotating machine element must have a keyway and a keyseat which is a slot and pocket in which the key fitsThe whole system is called a keyed joint Types of Shaft Keys Definition Use Function Advantages Keyseats and Keyways GDT Basics gdandtbasicscom Metric Key Keyway Dimensions Engineers Edge Why Power Transmission Shafts Have Both Keys and Keyways Lovejoy Inc Types Of Mechanical Keys Design Of Keys Keyways Shaft Arbor and Keyseat Dimensional Data American National Standard Keys and Keyways Standard Metric Keys Keyways for Metric Bores with One Key Keyway Cutter Hole Keyway Dimensional Data for MIlling Centers and Arbors ANSIASME B94191997 Keyway Stresses for Nonmetallic Gears and Shafts Formulas and Calculator For shafts too small for traditional shaft keys slots in the hub hold a dowel or pin inserted through the shaft In many instances particularly with couplings designs tabel pinjaman nsc finance cannot accommodate a Gib
