Abstract
The utility model relates to the technical field of pulleys, in particular to a fixed pulley. The fixed pulley is mainly used for a winch type headstock gear and is provided with a pulley shaft and a pulley arranged on the pulley shaft, wherein a friction rotating section is arranged at the contacted part of the pulley shaft and the pulley; the periphery of the friction rotating section is coated with a ceramic layer with the thickness of larger than or equal to 30mum; the ceramic layer comprises a bottom layer and a surface layer; the thickness of the bottom layer is larger than or equal to 100mum; and the thickness of the surface layer is larger than or equal to 200mum. According to the utility model, by arranging the ceramic layer, the friction contacted part of the pulley shaft has high combined strength; lubricating oil is not required during the use; the fixed pulley has the advantages of corrosion resistance, high wear resistance and high surface precision; and the hardness is improved and the friction coefficient is reduced, therefore the service life of the fixed pulley is prolonged.
Description
Technical field
The utility model relates to the pulley technical field, in particular for the static pulley on the winch hoist.
Background technique
When using pulley, the motionless pulley of fixed-site of axle is called static pulley.Its pulley of present static pulley is arranged on the pulley spindle, because pulley rotates with respect to pulley spindle, grinding away easily in the place that makes pulley spindle contact with pulley, influences its working life.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of static pulley is provided, and improve wear resistance.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of static pulley, have pulley spindle and the pulley that is arranged on the pulley spindle, pulley spindle and pulley contacting point scribble ceramic layer for friction rotation section, the periphery of friction rotation section, and the thickness range of ceramic layer is 〉=300um.
Further, described ceramic layer comprises bottom and top layer, and the thickness range of bottom is 〉=100um that the thickness range on top layer is 〉=200um.
The beneficial effects of the utility model are that a kind of static pulley of the present utility model is owing to scribble ceramic layer, make the rubbing contact place of pulley spindle have high bond strength, high wear resistance, high surface accuracy, improve hardness, reduced friction factor, thereby prolonged its working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, pulley spindle, 2, pulley, 3, ceramic layer.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of static pulley as shown in Figure 1 has pulley spindle 1 and is arranged on pulley 2 on the pulley spindle 1, and pulley spindle 1 is friction rotation section with pulley 2 contacting points, and the periphery of friction rotation section scribbles ceramic layer 3, and the thickness range of ceramic layer 3 is 〉=300um.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
