3、 subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; - type 3, when a technical committee has collected data of a different kind from that which is normally published as an Internat
4、ional Standard (“state of the art”, for example). Technical Reports of types 1 and 2 are subject to review within three years of publi- cation, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data th
5、ey provide are considered to be no longer valid or useful. ISO/TR 10657, which is a Technical Report of type 3, was prepared by Technical Com- mittee ISO/TC 4, Rolling bearings, Sub-Committee SC 8, Load ratings and life. ISO/TR 10657 has been prepared for the guidance of users of IS0 76 : 1987, Roll
6、ing bearings - Static load ratings. It is a purely scientific document intended for use by specialists in this field, and it is not envisaged that it will become an International Stan- dard. Annexes A, B and C form an integral part of this Technical Report. TECHNICAL REPORT ISO/TR 10957 : 1991 (E) E
7、xplanatory notes on IS0 76 1 Scope This Technical Report gives supplementary background information regarding the derivation of formulae and factors given in IS0 76, Rolling bearings - Static load ratings. 2 Brief History 2.1 ISO/R 76 - 1958 The IS0 Recommendation R 76, Ball and Roller Bearings - Me
8、thods of Evaluating Static Load Ratings, was drawn up by Technical Committee ISO/TC 4, Ball and Roller Bearings, the Secretariat of which is held by the Sveriges Standardiseringskommission (SIS). This Recommendation is based On the studiesl*, 2 by A. Palmgren and so on. It is defined in the Recommen
9、dation that the basic static load ratings correspond to a total permanent deformation of rolling element and raceway at the most heavily stressed rolling element/ raceway contact ef 0,OOOl of the rolling element diameter. And then the Standard values confined to the basic static load ratings for spe
10、cial inner design rolling bearings are laid down. * Figures in brackets indicate literature references in annex C. ISO/TR 10667 : 1991 (E) Technical Committee ISO/TC 4 discussed the questions dealt with by the IS0 Recommendation at the following meetings: the third meeting, held in Ggteborg, in Sept
11、ember 1953, the fourth meeting, held in Madrid, in May 1955, the fifth meeting, held in Vienna, in September 1.956. At the third meeting of the Technical Committee, Working Group No. 3 was appointed to assist the ISO/TC 4 Secretariat in preparatory work and in drawing up proposals. The Working Group
12、 composed of Germany, Sweden and USA held the following meetings: the first meeting, held in Madrid, in May 1955, the second meeting, held in Vienna, in September 1956. On 4th June 1957, the Draft IS0 Recommendation was sent out to all the IS0 member Bodies and was approved by 28 (out of a total of
13、38) Member Bodies. The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which decided, in December 1958, to accept it as an IS0 Recommendation. 2.2 ISO 76 - 1978 The Working Group No. 3 was transformed into X8 at the 13th meeting held in Paris in May 1972. The SC 8 S
14、ecretariat proposed to include the revision of ISO/R 76 in the future work at the first meeting held in London in November 1973, and SC 8 requested its Secretariat to prepare a Draft Proposal for an International Stan- dard replacing ISO/R 76 and it was decided that this proposal should be submitted
15、 to the SC 8 member Bodies for consideration prior to 1 October 1974 (SC 8 RESOLUTION 21, 21 London 1973). 2 ISO/TR 10667 : 1991 (E) The SC 8 Secretariat distributed a DRAFT PROPOSAL (Revision of ISO/R 76) in July 1974. The TC 4 decided to include the revision of ISO/R 76 in its. pro- gramme of work
16、 (TC 4 RESOLUTION 514, item No. 132) and SC 8 Sec- retariat was requested to prepare a Draft Proposal (SC 8 RESOLUTION 38, 13 Miami Beach 1974). As a result, the Secretariat submitted a DP 3 3 in January 1976. The Draft Proposal DP 76 was accepted by correspondence by 6 of the 8 Members of SC S. Of
17、the remaining two, Japan would prefer further study and USA its counter proposal, document 4/8 N 64 4. The DIS 76 was then submitted to the IS0 Central Secretariat. After the DIS had been irppro.xd by the IS0 Member Dodies, the IS0 Council decided in June 1978 to accept it as an International Standa
18、rd. This Standard adopted the SI unit newton and was revised in total, but without essential changes of substance. However, values of Xo and Yo far the nnminal contact angles 15 and 45 for angular con- tact groove ball bearings were added to the table which shows the values of X0 and Y. in the formu
19、lae to calculate the static equiva- lent radial loads of radial ball bearings. 2.3 I50 76 - 1987 During the revision of ISO/R 713 - 1958, USA had in 1975 submitted a counter proposal 4 f or the basic static load ratings based on a calculated contact stress. 3 ISO/TR 10657 : 1991 (E) The Secretariat
