Abstract
The invention belongs to the technical field of the hoist and particularly relates to a roll shaft. The roll shaft comprises a shaft body and a roll. The roll is arranged on the shaft body; the contact part of the shaft body and the roll is coated with a ceramic layer, wherein the thickness of the ceramic layer is not less than 300 mu m; the ceramic layer comprises a bottom layer and a surface layer, wherein the thickness of the bottom layer is not less than 100 mu m, and the thickness of the surface layer is not less than 200 mu m; the bottom layer is made from a NiC or NiCrAl alloy material; and the surface layer is made from a Al2O3 and TiO2 composite material or Cr2O3 and TiO2 composite material. The wear resistance of the structure of the roll shaft is improved and the service life is prolonged due to the performance of the ceramic.
Description
Technical field
The present invention relates to the headstock gear technical field, especially a kind of drum shaft.
Background technology
Drum shaft is made up of frame, lifting mechanism, electric control system.Lifting mechanism mainly is made up of parts such as assembly pulley, reel group, actuating device (comprising exposed gear pair, retarder, drg, electrical motor etc.) and safety devices, and headstock gear links to each other with gate by the suspender that is positioned on the assembly pulley movable pulley, to open and close gate.Its principle of work is: drive open gear pair and reel rotation by electrical motor by driving brake wheel coupler and retarder, steel rope is realized the lifting of suspender again on the reel by pulley and equalizer pulley.Wherein reel is arranged on the drum shaft because the rotation of reel, make and drum shaft between frictional strength bigger, make shorten the service life of drum shaft.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of drum shaft is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of drum shaft, have axis body and the reel that is arranged on the axis body, and scribble ceramic layer with the reel contact position on the axis body, ceramic layer thickness is for being not less than 300um.
Further, in order to improve resistance to abrasion, described ceramic layer comprises bottom and top layer, the thickness range of bottom is 〉=100um, the thickness range on top layer is 〉=200um, bottom is made by NiC or NiCrAl alloy, and the top layer is that Al2O3 and TiO2 composite material or Cr2O3 and TiO2 composite material are made.
The invention has the beneficial effects as follows: drum shaft of the present invention, owing to the performance of pottery, improved the wear resisting property of its structure, prolonged its service life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is local structure reel of the present invention and drum shaft structural representation.
Among the figure 1, drum shaft, 2, reel, 3, ceramic layer.
The specific embodiment
The present invention is further illustrated with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the scheme drawing of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of drum shaft of preferred forms as shown in Figure 1 has axis body and the reel 2 that is arranged on the axis body 1, scribbles ceramic layer 3 with reel 2 contact positions on the axis body 1, and ceramic layer 3 thickness are for being not less than 300um.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
