Abstract
The utility model relates to a shaft of a cooling water tank, which is used in a forced convection fan of an industrial furnace. The shaft is characterized in that the shaft sealing positions of the water tank on the shaft are respectively provided with chromium oxide ceramic coating which is more than 0.2mm thick. Compared with the prior art, the structure obviously enhances the abrasion resistance, prolongs the service life of the shaft, and reduces the maintenance loss of the industrial furnace.
Description
Technical field
The utility model belongs to a group on International Patent Classification (IPC), i.e. F16C, particularly the industrial furnace forced convection fan axle of cooling water tank.
Background technique
The uniformity of temperature distribution and the temperature of different periods height directly has influence on workpiece quality and manufacturing efficiency in the industrial furnace.Usually adopt the forced convection fan for this reason.The axle temperature degree of this flabellum is higher, needs the circulating water cooling of cooling water tank.Said waterbox design has the axle envelope, to stop the seepage of lubricant oil, still because axle in the wearing and tearing at axle envelope place, will cause lubricant grease to leak, causes damage of bearings to need shut-down (breakdown) mainteance when serious.
The model utility content
The purpose of this utility model is to provide a kind of special axis of above-mentioned cooling water tank, and it is wear-resisting to be not easy corrosion.
The new solution that realizes above-mentioned purpose is as follows:
A kind of axle of cooling water tank, the one end links to each other with drive wheel, and the other end is equipped with the flabellum of forced convection fan and is positioned at industrial furnace, it is characterized in that having on the axle two place's chromium oxide ceramics coating, lays respectively at the upper and lower axle of cooling water tank envelope place.
By the sample that such scheme is made, more wear-resisting through probationary certificate than prior art, obviously prolong working life, thereby reduced the shut-down (breakdown) mainteance loss.
Description of drawings
Figure is an embodiment's of the utility model a schematic representation, and wherein 1,2 is coating.
Embodiment
A kind of axle of cooling water tank, the one end links to each other with drive wheel, and the other end is equipped with the flabellum of forced convection fan and is positioned at industrial furnace, it is characterized in that having on the axle two place's chromium oxide ceramics coating 1,2, lays respectively at the upper and lower axle of cooling water tank envelope place.
The thickness of chromium oxide ceramics coating 1,2 is not less than 0.2mm.
Coating 1 width that leans on the flabellum side is greater than coating 2 width by the drive wheel side.
Because cooling water tank has different size, the width of axle envelope can change to some extent, and the width of coating 1,2 has different on accompanying drawing with particular location.
Claims (3)
1, a kind of axle of cooling water tank, the one end links to each other with drive wheel, and the other end is equipped with the flabellum of forced convection fan and is positioned at industrial furnace, it is characterized in that having on the axle two place's chromium oxide ceramics coating [1,2], lays respectively at the upper and lower axle of cooling water tank envelope place.
2, the axle of cooling water tank as claimed in claim 1 is characterized in that the thickness of chromium oxide ceramics coating [1,2] is not less than 0.2mm.
3, the axle of cooling water tank as claimed in claim 1 or 2 is characterized in that leaning on coating [1] width of flabellum side greater than coating [2] width by the drive wheel side.
