23、f this European Standard deals with the requirements for the design and manufacture of Guide Bearings and Restraint Bearings. Guide Bearings and Restraint Bearings are not intended to transmit vertical loads but they may be combined in one unit with bearings in accordance. EN 1337-1:2000, Table 1. N
24、OTE 1 Guide Bearings and Restraint Bearings are shown in EN 1337-1:2000, Table 1, No. 8.1 and 8.2. For combined bearings see EN 1337-1:2000, Table 1, bearing Nos. 1.2, 1.3, 1.6, 1.7, 1.8., 3.1, 4.1, 4.2, 4.3, 7.1, 7.3, and 7.4 with restraints and Nos. 1.5, 1.7, 2.2, 3.3, 3.4, 5.2, 6.2 and 7.3 with g
25、uides. NOTE 2 Examples of combined bearings are given in Annex B. The minimum operating temperature depends on the materials properties used at the required temperature and the limitations given in the referenced parts of this European Standard. NOTE 3 In certain circumstances the bearings described
26、 in this part of this European Standard may be required to operate in a plane inclined to the horizontal. In such circumstances the terms “vertical“ and “horizontal“ should be interpreted appropriately. 2 Normative references The following referenced documents are indispensable for the application o

37、 CM Composite Material PTFE Polytetrafluoroethylene 4 Functional Requirements 4.1 General Guide bearings and restraint bearings shall be designed to: transmit horizontal forces; allow vertical movements; allow movements in one or no horizontal directions; allow rotations; generate low resistance to
38、movement; have durability appropriate to their intended use. NOTE As a consequence of the above these devices do not transmit applied vertical loads and bending moments.

The movement capacity shall be verified by geometrical analysis under the fundamental combination of actions. The ho
46、rizontal movement capacity shall be increased by the values given in EN 1337-1:2000, sub-clause 5.4. The vertical design movement capacity shall be at least the following: 15 mm upwards; 10 mm downwards. For the design of the combined units (see 1 Scope) the Part of this European Standard relevant t

In this case the friction coefficient shall be taken as 0,6
48、. The combination of the materials in contact shall be such as to avoid cold welding. NOTE Cold welding may be avoided by using the design rules given in EN 13375:2005 clause 6.2.3. Notice lubrication and dust protection of the contact zone. 6.3 Minimum plate thickness If used, the minimum thickness
49、 t of bearing plates and of anchor plates shall be that: determined from stress verification; or calculated according to equation (1): (1) or 17 mm; whichever is the greatest. 6.4 Connection to Packing and Anchor Plates The connections between the bearing plates, packing plates, anchor plates and the main structure shall be capable of transmitting the applied forces and allow the bearings to be replaced if necessary.
