4、SO/TR 8517 was prepared by Technical Committee ISOITC 45, Rubber and rubber products. It was decided to publish this document in the form of a technical report type 3 because the information it contains is related to the “state of the art” in the industry rather than pro- viding a definitive vocabul
5、ary as in the case of IS0 1382.

8、itions in this Technical Report, “roller” is treated as a synonym for “rubber- or plastics-covered roller”. Therefore care should be taken to ensure that the word is not used out of context, because it does have other meanings. 3 For the purposes of the definitions in this Technical Report, “rubber”
9、 as defined in IS0 1332 is treated as a synonym for “soft rubber” or “hard rubber” or “ebonite”. The term “rubber” can be replaced by “plastics” as defined in IS0 472 or “elastomer” without change in meaning, It will be understood that the properties of a roller cover vary depending on its compositi
10、on and surface finish, and therefore it should not be assumed that rubbers, ebonite and plastics are interchangeable. 2 References IS0 472, Plastics - Vocabulary IS0 1382, Rubber - Vocabulary IS0 1925, Balancing - Vocabulary.

NOTE - The purpose of the cover may be to facilitate the
12、removal of liquid from material being processed, to facilitate the coating and im- pregnation of surfaces, to provide protection for the core and the material being conveyed, to impart high-friction characteristics to the roller, etc. 4 Construction terms 4.1 roller: A body of circular cross-section
13、 designed to revolve about a fixed axis. 1 Objet et domaine dapplication Le present Rapport technique contient des definitions de ter- mes couramment utilises dans Iindustrie de revetement des cylindres (rouleaux). II ne comprend pas les termes generaux de Iindustrie du caoutchouc, par exemple vulca
14、nisation, durete Shore, etc., pour lesquels il faut se reporter a IISO 1392; il ne comprend pas non plus les termes de Iingenierie mecanique, tels que axe, etc. NOTES 1 Lorsquun terme a un ou plusieurs synonymes, les synonymes sui- vent le terme preferentiel. 2 Dans le cadre des dbfinitions du prese
15、nt Rapport technique, le terme ( cylindre (rouleau) 1) est pris comme synonyme de ( cylindre (rouleauj rev body; stock : A rigid cylinder (with journals - see 4.5) to which a rubber cover is applied. 4.2 corps; manche: Cylindre (rouleau) rigide (avec tourillons) sur lequel est applique un revi+temen

17、oviding the working face of the roller and protecting the core if necessary. 4.4 enveloppe; revbtement : Couche de caoutchouc collee sur la surface de IGme, constituant la surface dapplication du cylindre (rouleau) et protegeant Idme si necessaire. 4.5 journal : The end shaft on which a roller rotat

19、se t for instance. 5.6 charge de contact: Force totale supportee par la sur- face du cylindre (rouleau) divisbe par la longueur de contact. NOTE - La charge de contact est exprimbe, par exemple, en newtons par millim camber: Convex or concave curvature or taper along the length of a roller face line
20、, It is expressed as the dif- ference between the dlameter at the centre of a roller cover and the diameter at reference points near the ends. 6.6 bombage; cambrure : Courbure convexe ou concave ou c8ne le long dune ligne de surface. Elle est exprimee comme inverse camber: Concave curvature or taper
21、 along the length of a roller face line. 6.6.1 bombage inverse; cambrure inversee: Courbure con- cave ou conique le long dune ligne de surface du cylindre (rou- leau). 6.6,2 taper crown; taper camber: A type of crown in which the diameter changes linearly from the centre to each end. 6.6.2 bombage c
22、onique; cambrure conique : Type de bom- bage oh le diametre change lineairement entre le centre et cha- que extrt5mit4. 4 ISO/TR 8517 : 1988 (E/F) 6.6.3 barrel crown; barrel camber: A type of crown in which the diameter decreases non-linearly from the centre to each end. NOTE - Barrel crown or barre
23、l camber is expressed as the difference between the diameter at the centre of a roller cover and the diameter at reference points along the face. 6.6.4 measured crown face: The length of cover over which the crown extends, excluding the length of any edge relief at each end of the roller. 6.6.6 comp
24、ound crown: A crown profile formed by the superposition of one or more crowns on a primary crown. NOTE - A compound crown is used if the cylindrical surfaces do not deflect as a uniformly loaded beam. This condition can be caused by flattening of the cylindrical surface, expansion of the surface due
25、 to internal pressure and/or distortion of the surface by heat. 6.6.6 primary crown : The first crown applied on a roller that is going to receive a compound crown. NOTE - The primary crown shape is an approximation of the deflec- tion of a uniformly loaded beam (see also 6.6.3). 6.6.7 secondary cro
26、wn: A crown superimposed on a primary crown to alter the shape of the crown on each side of the centre line of the primary crown. 6.6.6 tertiary crown: A crown superimposed on a second- ary crown to alter further the crown shape at each end of the roller face. 6.6.9 blend point: The point of interse
27、ction or tangential contact between a primary and secondary crown or a second- ary and tertiary crown. 6.7 edge finish; end relief: The relief of the cover at the end of the face length of the roller. NOTES 1 Reduction of diameter at the edge of the cover is intended to relieve internal tensions due
28、 to excessive end pressure. 2 In the case of uncovered ends, the edge of the cover may be square, rounded (radiused), bevelled (chamfered), dubbed, etc. (see the figure). 6.7.1 square: !30 angling of the edge of a roller cover. 6.7.2 round; radiused: Rounding of the edge of a roller cover. 6.7.3 bev

NOTES 1 La reduction du diametre au niveau de larete du revbtement
30、 est prevue pour relacher les tensions internes dues a une pression exces- sive sur les extremites. 2 Dans le cas dextremites non revetues, larete du revstement peut i%e carree, ronde (arrondie), biseautee (chanfreinee), enfoncee, etc. (voir la figure). 6.7.1 cart% : Angulation B W de Iar arrondi :
