11、d Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a
12、 technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matte
13、rs of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circula
14、ted to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsibl
15、e for identifying any or all such patent rights. ISO 1977 was prepared by Technical Committee ISO/TC 100, Chains and chain sprockets for power transmission and conveyors. This second edition cancels and replaces the first edition (ISO 1977:2000), Figures 2 and 5, as well as 5.4 and 5.5, of which hav
16、e been technically revised.

17、O 2006 All rights reserved v Introduction ISO 1977 combines into a single document ISO 1977-1, ISO 1977-2 and ISO 1977-3, which covered metric-series chains and attachments, and chain wheels, while at the same time revising their technical content. The principle technical changes are: a reduction in
18、 the flanged roller dimensions and the width between outer plates in the MC series of chains, an increase in the width between inner plates in M-series, MC56, MC112 and MC224 chains, and the addition of the small roller diameter to the MC series. New information on the calculation of sprocket tip di
19、ameters and tooth heights above root diameters is also given.

21、2006(E) ISO 2006 All rights reserved 1 Conveyor chains, attachments and sprockets 1 Scope This International Standard specifies the characteristics of bush, plain and flanged roller chains of both solid and hollow bearing pin types designed for general conveying and mechanical handling duties, toget
22、her with associated chain sprockets and attachments. The chain dimensions specified in this International Standard will ensure interchangeability of complete chains and individual links for repair purposes. This International Standard is applicable to sprockets with from 6 to 40 teeth. Control crite
23、ria for sprockets are defined to ensure correct meshing, operation and transmission of load in use under normal operating conditions. NOTE Controls do not necessarily determine sprocket design parameters. Specifications are also given for K attachments and deep plates for use with the conveyor chain
24、s conforming to this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any am
25、endments) applies. ISO 286-2, ISO system of limits and fits Part 2: Tables of standard tolerance grades and limit deviations for holes and shafts. 3 Chains 3.1 Nomenclature The nomenclature of the chains and their component parts is presented in Figure 1. 3.2 Dimensions Conveyor chain dimensions sha
26、ll conform to those given in Table 1 or Table 2 (see Figure 2). Both maximum and minimum dimensions are specified to ensure the interchangeability of links made by different chain manufacturers. Although these represent limits for interchangeability, they are not necessarily to be regarded as limits
27、 of tolerance for manufacture.

The ends shall be attached to the testing-machine shac
44、kles by a pin through the plate holes or the bushes. The shackles shall be designed so as to allow universal movement. The actual test method shall be left to the manufacturers discretion. Tests in which failures occur adjacent to the shackles shall be disregarded. 3.4 Length accuracy 3.4.1 General
45、When measured in accordance with the requirements given in 3.4.2, 3.4.3 and 3.4.4, the finished chain shall be accurate to within 0,25 0 % of the nominal chain length. NOTE Chains that work in parallel can be matched by agreement between the purchaser and manufacturer. 3.4.2 Standard test-measuremen
46、t length The length of chain for measurement shall be that nearest to 3 000 mm with an odd number of pitches, terminating with inner links at each end. 3.4.3 Support The chain, in unlubricated condition, shall be supported throughout its entire length. 3.4.4 Measuring force A force equal to 1/50 of
47、the appropriate tensile strength given in Table 1 or Table 2 shall be applied. 3.5 Cranked links In order to obtain an odd number of pitches in an endless chain, a cranked link is used see Figure 1 h) and 1 i). The cranked link dimension of a chain shall correspond to its respective l1 as given in Table 1 or Table 2 and as appropriate. 3.6 Designation The designation numbers for conveyor chains are based on the ISO numbers given in Table 1 and Table 2. These numbers are derived from the minimum tensile strength (in kilonewtons) and have been given the prefixes M, to indicate a
