Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram that the each parts of the utility model preferred embodiment decompose.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the utility model preferred embodiment comprises central shaft 1, bearing housing 2, bearing 3, pad 4, nut 5.
As shown in the figure, central shaft 1 is cylindrical, is provided with the oblique through hole 10 being beneficial in cable insertion cylinder therein and alongst.When application, bearing housing 2 is fixed in roller tube.Preferably, bearing housing 2 adopts the material manufacture identical with cylinder, is convenient to itself and cylinder to weld, and guarantees that bearing housing 2 skew can not occur and causes cylinder distortion.In addition, bearing housing 2 can be directly and roller tube make integrative-structure.Bearing 3 is preferably spot contact bearing, and it should adopt corrosion-resistant and be made with the material that plating solution does not react, and stops because bearing pollutes plating solution, such as being PP(polypropylene), PE(polyethylene) and glass etc.When assembling, bearing 3 is installed in bearing housing 2, for example, in bearing 3 embedded axle bearing sleeve 2 rear end endoporus 22.And the middle part 12 of central shaft 1 is rotatably located in the endoporus 31 of bearing 3.
Preferably, the rear end 13 of central shaft 1 is provided with outside screw vertically, after through bearing 3, pad 4, is connected with the inner hole thread of nut 5.The pad 4 of annular is located between nut 5 and bearing 3, and endoporus 41 apertures of pad 4 equal the external diameter in central shaft 1 stage casing 12 of corresponding position.
In other embodiments, also can use the mode outside being threaded that the rear end of central shaft 1 13 is fixed, for example welding.
In addition, the overall dimensions of central shaft 1 is trapezoidal variation, the external diameter of its rear end 13, stage casing 12 and front end 11 increases successively, the external diameter of central shaft 1 front end 11 equals the aperture of the endoporus 21 of bearing housing 2 front ends, the external diameter in the stage casing 12 of central shaft 1 equals the aperture of the endoporus 31 of bearing 3 and the endoporus 41 of pad 4, the external diameter of central shaft 1 rear end 13 is slightly less than the aperture of the endoporus 31 of the endoporus 21 of bearing housing 2 and endoporus 22, bearing 3, and while being beneficial to assembling, its rear end 13 is through bearing housing 2, bearing 3 etc.
