Pot bearings overall performance of the mechanical test, generally include vertical bearing capacity, friction coefficient and rotational performance test, the test should be carried out in the manufacturing line or specialized testing facility. 1. Capacity Test pot bearing vertical vertical bearing capacity of pot bearings www.grgcxj.cn test, generally vertical test load shall be 1.5 times the design load, the test should be placed in the test pot bearings aircraft carrier plate central location in the test stand four symmetrically placed around the dial indicator measured vertical compression, during the test, you should first pre-press, pre-press load bearing generally vertical design load, the number of pre-press to 3 times better. Pot bearings in the design of vertical compression deformation under load shall not exceed 2% of the total height of the seat, basin ring radial deformation shall not exceed 0.05% pots ring diameter. Test test pot bearing friction coefficient 2. pot bearing friction coefficient should be on a dedicated double shear friction test apparatus, the test will be safe pot bearings placed in double shear combination tester load board specimen center and the center of the plate carrier alignment. During the test, the first should be preloading the bearings in a continuous vertical design load to fill a uniform rate, to be regulated uninstall preload repeated three times. Official after loading preload applied first vertical design load bearing, then the level of loading device continuously applied horizontal force evenly, while calculating the initial friction coefficient of bearing. During the test three times in a row, three times the average of the measured coefficient of sliding friction as measured coefficient of friction bearing. Bearing friction coefficient should satisfy: Normal-type movable carriage is not greater than 0.03, cold-type bearing activities require no more than 0.06. Www.hsgrgc.com essentials pot bearings installed a recommended set support cushion stone. 2. Install the front bearing activities carefully cleaned with acetone or alcohol relative to each slip plane, after wiping the inside of Nagisa PTFE slide grease sump filled ≤295 ≥ lubricant and grease cleaning attention. Supports various other parts should also be cleaned. 3, bearing in addition to elevation meet the design requirements, to ensure that the two parties Queensland to the horizontal plane is very important. Otherwise it will affect the performance of the role of bearing, bearing corners height not greater than 2 mm. 4, bearing down on various aspect to be, when the installation temperature and the temperature is not the same design, the upper and lower bearing activities subject to a variety of staggered distance calculation. 5, when the one-way bearing activities installation, vertical guide dog must remain parallel, intersecting angle not greater than 5 °. 6, bearing centerline should coincide with the main beam parallel to the centerline. 7. When you install the foot of the exposed screw nut body height not greater than the thickness of the top surface of the nut. 8, continuous beam bridges in the implementation of the system when the conversion to cut temporary anchorage devices, insulation measures must be taken between the bearing and sulfur, cement, mortar, block, with mortar between the block insulation measures taken to avoid damage to tetrafluoroethylene plates and plastic pieces.
