Two end-plates 3 are separately fixed at the two ends of bearing pin 2, and in the present embodiment, end-plate 3 and bearing pin 2 are for being threaded.The two ends that are bearing pin 2 are provided with screw thread, and all offer screwed hole on two end-plates 3, and bearing pin 2 two ends are inserted in the screwed hole of end-plate 3 respectively, and pass through screw threads for fastening.
Two slippage axle sleeves 5 are set on the bearing pin 2, and one of them slippage axle sleeve 5 apical grafting is between an end-plate 3 and plain radial bearing 1, and another slippage axle sleeve 5 apical graftings are between other end shrouding 3 and plain radial bearing 1.The effect of slippage axle sleeve 5 is when the skew that plain radial bearing 1 takes place on the left and right directions, and it is subjected to transferring on the end-plate 3 from the power of plain radial bearing 1.
Two bearing otic placodes 7 are set in respectively on two slippage axle sleeves 5, and it and can carry out relative the slip with slippage axle sleeve 5 between plain radial bearing 1 and end-plate 3.Two bearing otic placodes 7 all will and plain radial bearing 1 between leave the gap so that plain radial bearing 1 has slidably space.In the present embodiment, also be provided with self-lubricating external member 6 between bearing otic placode 7 and the slippage axle sleeve 5, so that more successfully slide relatively between bearing otic placode 7 and the slippage axle sleeve 5, the self-lubricating external member can be that thickness is the ring flat-plate of 12mm.The lower end of bearing otic placode 7 connects built-in fitting 11, and therefore as the support of bearing, it will have higher intensity, and preferred bearing otic placode 7 thickness are 120mm, and middle opening diameter is than the big 24mm of diameter of section of slippage axle sleeve 5.
