7、SI, United Kingdom). The responsible German body involved in its preparation and which made the decision to have it translated into German and included in the body of German Standards, with the withdrawal of all relevant national standards, was the DIN-Normenausschuss Maschinenbau (DIN Standards Com
8、mittee Mechanical Engineering), Working Committee NA 060-34-35 AA Stahlgelenkketten of Section Antriebstechnik. The work involved in the national adoption of the International Standard is a one-time affair, which saves considerable time and money as compared with the development of additional nation
9、al standards on the same type of chain. The Committee has thus documented the fact that this standard is consistent with the ISO Standard. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN and/or DKE shall not be held responsibl
10、e for identifying any or all such patent rights. This standard (DIN ISO 1977) supersedes DIN 8167 Part 1, DIN 8167 Part 2 and DIN 8167 Part 3 as well as DIN 8168 Part 1, DIN 8168 Part 2, DIN 8168 Part 3 and DIN 8169. Amendments This standard differs from DIN 8167-1:1986-03, DIN 8167-2:1986-03, DIN 8

12、ion in delivery condition have been deleted; e) variables for the definition of chain dimensions have been partly changed; f) Table 1 has been changed as follows: a) some chain types and pitches are for bush and small roller chains only, b) permissible chain pitches have been extended to various cha
13、in sizes, c) the maximum roller width has not been restricted, d) the flange roller diameter d5for chain M20 has been increased from 30 mm max to 32 mm max, e) the plate thickness is no longer defined as the nominal size, f) the plate depth h2is generally larger but defined as the maximum size, g) t
14、he flange roller width b11has been redefined and restricted as a maximum value. g) specifications concerning the distance between centres and clear widths of double-strand chains have been deleted; h) specifications concerning tensile force, permissible stress and joint surface have been deleted; i)
15、 in Clause 4 “Attachments”, L profiles for welded-on angles have not been included; j) the longitudinal distance between hole centres (Table 3) can now be freely selected; k) attachment dimensions now also apply to the MC series of hollow bearing pin chains; l) for deep link chains, the same additio
16、ns apply as for conveyor chains according to this standard; m) Clause 5 “Sprockets” has been added; n) type C plain rollers and type G flanged rollers as given in DIN 8169 have been deleted; o) the flange diameter of the flanged rollers has been adopted without any changes from ISO 1977; the toleran
17、ces of some flange diameters as given in DIN 8169 have been deleted.

18、76-07, 1986-03 DIN ISO 1977:2014-12 4 National Annex NA (informative) Correction to Subclause 5.2.4, p. 15, which states: “When slats are attached to the K attachment platforms and the starts bridge the chain link, the tip of the tooth shall not project above the chord of the pitch circle by any mor
19、e than 0,8h4,where h4is the platform height of the attachment according to Table 3.” The factor 0,8h4given here does not apply in all cases, because certain combinations in which the number of teeth is low and the pitch is large can cause the sprocket to collide with slats attached above the chain.
20、DIN ISO 1977:2014-12 5 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 the f
21、langed 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 diameter
22、s and tooth heights above root diameters is also given. DIN ISO 1977:2014-12 6 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 conveyi
23、ng and mechanical handling duties, together 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 sprocket
24、s with from 6 to 40 teeth. Control criteria 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 dee
25、p plates for use with the conveyor chains 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 t
26、he referenced document (including any amendments) applies.

27、Dimensions Conveyor chain dimensions shall 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
28、not necessarily to be regarded as limits of tolerance for manufacture.

DIN ISO 19 77:2014-12 10 3.3 Tensile testing The test length sh
41、all have a minimum of three free pitches. The ends shall be attached to the testing-machine shackles 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
42、failures occur adjacent to the shackles shall be disregarded. 3.4 Length accuracy 3.4.1 General 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 0,250% of the nominal chain length. NOTE Chains that work in parallel can
43、be matched by agreement between the purchaser and manufacturer. 3.4.2 Standard test-measurement 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, sh
44、all be supported throughout its entire length. 3.4.4 Measuring force A force equal to 1/50 of 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
45、 i). The cranked link dimension of a chain shall correspond to its respective l1as 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
46、 strength (in kilonewtons) and have been given the prefixes M, to indicate a solid bearing pin chain, and MC, to indicate a hollow bearing pin chain. EXAMPLE M80 signifies a solid bearing pin chain of 80 kN tensile strength. MC224 signifies a hollow bearing pin chain of 224 kN tensile strength. The
47、addition of the letter B, F, P or S indicates type: bush, flanged roller, plain or small roller, respectively. The addition of further digits indicates the pitch in millimetres. EXAMPLE MC224 chain with flanged roller and pitch of 200 mm: MC224-F-200 3.7 Marking The chains shall be marked with the m
48、anufacturers name or trademark, and should be marked with the respective ISO chain number given in Table 1 or Table 2. DIN ISO 1977:2014-12 11 4 Attachments 4.1 K attachments 4.1.1 Dimensions K attachments are shown in Figure 3, and their respective dimensions are given in Table 3. 4.1.2 Designation This International Standard specifies three types of K attachment: K1, which has one attachment hole centrally disposed in each plate; K2, w
