6、:1985 ii BSI 12-1999 National foreword This BritishStandard has been prepared under the direction of the Machinery and Components Standards Committee. It is identical with ISO4863:1984 “Resilient shaft couplings Information to be supplied by users and manufacturers”, which was prepared by ISO/TC108,

7、 Mechanical vibration and shock, of the International Organization for Standardization (ISO). ISO4863 was produced as a result of international discussion in which the UK took an active part. Terminology and conventions. The text of the International Standard has been approved as suitable for public

8、ation as a BritishStandard without deviation. Some terminology and certain conventions are not identical with those used in BritishStandards; attention is drawn especially to the following. The comma has been used as a decimal marker. In BritishStandards it is current practice to use a full point on

9、 the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “BritishStandard”. Cross-reference. The Technical Committee has reviewed the provisions of ISO2041:1975, to which reference is made in the text, and has decided

10、 that they are acceptable for use in conjunction with this standard. A related BritishStandard to ISO2041 is BS3015:1976 “Glossary of terms relating to mechanical vibration and shock”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standar

11、ds are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 and2, an inside back cover and a back cover. This standa

This will be indicated in the amendment table on the inside front cover.BS6613:1985 BSI 12-1999 1 0 Introduction Resilient shaft couplings are generally introduced into transmission systems to provide a degree of prot

13、ection from shock or to tune out vibrations. Some couplings can also accommodate misalignment. However, misalignment is considered in this International Standard only in so far as it affects operation of the couplings. Introduction of a resilient shaft coupling into a transmission system will affect

14、 its torsional, axial, rotational and alignment characteristics. It is recommended, therefore, that the choice of a coupling for complex transmission systems be based upon a comprehensive analysis of the complete system. 1 Scope and field of application This International Standard specifies the info

15、rmation to be supplied by users and manufacturers of resilient shaft couplings in order to facilitate communication and understanding between users and manufacturers. It is strongly recommended that its provisions be adhered to in all cases, unless there are good reasons for departing from them. Thi

16、s International Standard does not apply to a) rigid flange or sleeve couplings; b) torsionally stiff couplings for alignment purposes, such as toothed or diaphragm couplings, etc.; c) all types of slip couplings; nor does it give dimensional requirements for either shafts or couplings. 2 Reference I
