9、tions referred to Inside back coverBS3876-1:1990 ii BSI 11-1999 Foreword This Part of BS3876 has been prepared under the direction of the Mining and Quarrying Requisites Standards Policy Committee (MQE/-) and is a full technical revision of both BS3876-1:1965 and BS3876-4:1966 both of which are with
10、drawn. The other Parts in the revised edition of BS3876 are as follows: Part2: Specification for vertical spindle pulleys, mountings and assemblies; Part5: Specification for suspended pulley assemblies and clamps. In the revised Parts, the following points should be noted: a) tapered rollers, covere
11、d in BS3876-2:1965, are now omitted from the revised Part2; b) vertical rollers, which were included in the1965 edition of Part2, are now omitted as it is considered the parallel barrel rollers specified in Part1 can be used in the vertical mode; c) horizontal spindle pulleys, covered in the1965 edi
12、tion of Part2, are relocated in Part5 of the revised edition; d) Part3:1965 has been withdrawn because there is no longer any requirement for rollers with non-metallic rope bearing surfaces; e) the requirements for mountings for parallel barrel rollers, previously specified in BS3876-4:1966, have be
13、en revised and incorporated into this expanded edition of Part1; there is therefore no need for retention or revision of a separate Part4. During the revision, all dimensions have been metricated and these are not necessarily straight conversions from the imperial dimensions previously adopted. In p
14、articular, barrel diameters have been adjusted to align with the outside diameters of metric tubes now available. Product certification. Users of this British Standard are advised to consider the desirability of third party certification of product conformity with this British Standard based on test
15、ing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS5750. Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Association of Certification Bodies. If a third party cer
16、tification scheme does not exist, users should consider approaching an appropriate body from the list of Association members. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Complianc
17、e with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front 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 a
18、mendments incorporated. This will be indicated in the amendment table on the inside front cover.BS3876-1:1990 BSI 11-1999 1 1 Scope This Part of BS3876 specifies requirements for fabricated and cast steel rope rollers, mountings and roller assemblies intended for use in colliery track haulage. This
19、Part applies to a) rollers, with or without incorporated wind-back facilities and supplied without mountings, for which the diameters of the roller barrels do not exceed the lengths of the rollers to the outsides of their flanges; b) mounting, either high or low type and dependant upon roller diamet
20、ers; and c) roller assemblies that comprise both the rollers and the mountings. NOTE 1Appendix A gives the information which should be supplied by the purchaser, in his enquiry and/or order for rollers, mountings or assemblies in accordance with this Part of BS3876. NOTE 2Appendix B gives the inform
21、ation that will be required by the purchaser, to be provided by the supplier, prior to the supply of rollers, mountings or assemblies in accordance with this Part of BS3876. NOTE 3Appendix C gives general recommendations for the design and operating speeds for colliery track haulage rollers. NOTE 4N
22、o inspection requirements are specified in this Part of BS3876. However, a typical requirement that the purchaser may choose to write into his order or contract for rollers, mountings or assemblies to this Part is given in Appendix D. NOTE 5The titles of the publications referred to in this Part of
23、BS3876 are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS3876, the following definitions apply. 2.1 barrel that part of the roller cylinder on which the rope runs 2.2 roller a cylinder that is free to rotate to support or guide a moving rope, having a parallel bar
24、rel, parallel or taper sided flanges, windback facilities when required, complete with spindle and bearings 2.3 roller end/end cap a casting or fabrication at each end of the cylinder that contains the flange, bearing housing and windback facility when required NOTEIn the case of cast roller cylinde
25、rs, the ends are parts of the casting. In the case of fabricated roller cylinders, the end caps are fixed by welding or by tie-rods. 2.4 windback facility a scrolled configuration forming part of the roller end/end cap the effect of which is to impart a lateral movement, towards the roller barrel, t
26、o any moving haulage rope in contact with the scroll in either direction of roller rotation 2.5 throw (eccentricity) the total variation from true running of the periphery of the barrel when rotated on the spindle 1) 2.6 mounting the frame to which the roller is, or is to be, attached 2.7 roller ass
27、embly the roller and its mounting 3 General The roller components and mountings shall comply with the requirements specified in clauses4 to7, as appropriate. 4 Dimensions and shape of roller components and mountings 4.1 Dimensions The dimensions of the roller components and mountings shall be as giv
28、en in Table 1 to Table 4. NOTEFor convenience, typical rollers and mountings are illustrated in Figure 1 to Figure 4 which identify the dimensions referred to in Table 1 to Table 4. 4.2 Eccentricity of the barrels The eccentricity of the barrel when determined at the fixed points BB shown in Figure
29、5 (i.e.the radial run out as defined in BS308-3), shall not exceed the following: a) 1.5mm, for barrels up to and including168mm diameter; and b) 2.3mm, for barrels exceeding168mm diameter. 1) SeeFigure 5.BS3876-1:1990 2 BSI 11-1999 NOTEThis figure does not purport to show design details.
