10、rBS2567:1997 ii BSI 10-1999 Foreword This British Standard has been prepared by Technical Committee MHE/9, Continuous mechanical handling equipment, and is a revision of BS2567:1972 which is withdrawn. This revision was undertaken as a general updating of the standard to bring into it advances in no
11、n-powered roller conveyor design since the last edition. A wider range of roller sizes and roller materials have been incorporated including (acrylonitrile-butadiene-styrene) (ABS). Skate wheels as an alternative to rollers have also been added. All dimensions are now specified in metric units. A Br
12、itish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards 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 fr
13、ont cover, an inside front cover, pagesi andii, pages1 to12, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS2567:1997 BSI 10-1999 1 1 Scope
14、This British Standard specifies the main dimensions and materials for the rollers, skate wheels and supporting frames for straight and curved sections of fixed and portable non-powered roller conveyors for industrial use. Normative Annex A lists the information that shall be obtained from the purcha
15、ser and normative Annex B lists the information that shall be obtained from the manufacturer. Guidance on the design of a conveyor is given in informative Annex C. The standard only covers the sections that are used to make a conveyor system. The maximum permissible loading of any section of a conve
16、yor is dependent on the installation arrangements, which are not standardized. The actual performance requirements of sections or conveyor systems do not form part of this standard. This standard does not cover the safety of roller conveyors. NOTEA series of European Standards is being prepared to g
17、ive recommendations on the safety of conveyors. Reference should be made to these standards when a conveyor system is being designed, manufactured or installed. 2 Normative references This British Standard incorporates, by dated or undated reference, provisions from other publications. These normati
18、ve references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to or revisions of the cited publication apply to this British Standard only when incorporated
19、in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 3 Definitions 3.1 For the purposes of this British Standard the following definitions apply. 3.1.1 frame section a fabricated framework of straight or
20、 curved form constructed to mount the spindles for the rollers or skate wheels NOTETypical frame members and flames are shown inFigure 1, Figure 2, Figure 3 and Figure 4. 3.1.2 stand a fabricated steel frame to support the conveyor frame section(s) and to raise the conveyor bed to the required worki
21、ng height above floor level 3.1.3 roller conveyor a frame section(s), fitted with rollers, which may be mounted on a stand. The unpowered rollers extend to the width of the frame section(s) and are freely rotatable by the passage of loads on the conveyor 3.1.4 skate wheel conveyor a frame section(s)
22、, fitted with skate wheels, which may be mounted on a stand. The unpowered skate wheels mounted on fixed shafts are freely rotatable by the passage of loads on the conveyor 3.1.5 pitch the pitch, p, is the distance between centres of rollers or skate wheel spindles 3.1.6 spindle a round or hexagonal

24、nd spindle dimensions for steel rollers shall be in accordance with Table 1 and Table 2. NOTEThe ranges of loadings given in Table 1, Table 2, Table 3 and Table 4 are for guidance in the selection of rollers for a particular duty. The allowable loading for a particular installation depends on the be

NOTE 1The most satisfac
45、tory gradients and transition gradients vary according to the type and weight of the load to be carried. NOTE 2The presence of curved sections, junctions and guide rails in the system reduces the effect of the slope, thus requiring a greater angle of gradient than a straight conveyor of equivalent d
