Foreword T HIS standard on Woodruff Keys and Keyseats is a revision of USA Standard Woodruff Keys, Keyslots and C
6、utters, USAS B17f-1930, which standard was developed by subcbmmittee No. 5 of USA Standards Committee B17 on Shafting. The subcommittees initial work was started in 1925 and after nu- merous drafts and revisions was accepted by industry and designated by ASA (later changed to USASI) as an American S
7、tandard on December 31, 1930. The B17f-1930 standard was reaffirmed in 1955 but it was recognized that the standard was not in conformity with current practice. In 1962 the USA Standards Committee B17 was reactivated and a sub committee developed and established this updated standard on Woodruff Key
8、s and Keyseats which is in part a revision of B17f- 1930. Following approval by the USA Standards Committee B17 and the sponsor, the proposed revision was approved on September 18, 1967 by the USA Standards Institute, and redesignated B17.2-1967. USA STANDARD This USA Standard is one of nearly 3000
9、standards approved as American Standards by the American Standards Association. On August 24, 1966, the ASA was re- constituted as the United States of America Standards Institute. Standards approved as American Standards are now designated USA Standards. There is no change in their index identifica

It represents manufacturing practices for sizes and types from yu in. X in. thru in. X 3% in. covering 66 listings. Material, heat treatment, hardness or fini
15、sh is not within the scope of this standard. Dimensional features only are included. 2. Definitions Woodruff Key. A demountable machinery part which, when assembled into keyseats, provides a positive means for transmitting torque between the shaft and hub. Woodruff Key Number. An identification numb
16、er by which the size of key may be readily determined (see footnote to Table 1). Woodruff Keyseat - Sbajt. The circular pocket in which the key is retained. Woodruff Keyseat - Hub. Ah axially located rectangular groove in a hub. (Has been referred to as a keyway.) Woodruff Keyseat Milling Cutter. An
17、 arbor type or shank type milling cutter normally used for milling Woodruff keyseats in shafts.
