Abstract
The invention relates to a main shaft bushing of a textile machine, which comprises a main shaft bushing body, wherein a Cr3C2-NiCr metal ceramic compound coating layer prepared by spraying supersonic flame is arranged outside the main shaft bushing body; the Cr3C2-NiCr metal ceramic compound coating layer is 50-700 microns in thickness; and the porosity of the Cr3C2-NiCr metal ceramic compound coating layer is 1-2 percent. The main shaft bushing of the textile machine has the advantages that a low-carbon steel with low cost is adopted as a basis material and a wear resistant plasma spraying layer is produced outside a transmission shaft, so that the wear resistant performance of the transmission shaft is guaranteed, the production cost is effectively reduced, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of lining, relate in particular to a kind of loom mainshaft bushing.
Background technique
Existing textile machines main shaft sleeve is in order to guarantee wear-resisting property, mostly use Martensitic Stain Less Steel or high chromium manganese carbon steel as making material, although adopt these materials to guarantee to a certain extent the wear-resisting property of mainshaft bushing, but, the manufacture cost of mainshaft bushing significantly rises, and causes its practicability to reduce a lot.
Summary of the invention
Technical problem to be solved by this invention is, a kind of loom mainshaft bushing that effectively reduces manufacture cost when guaranteeing the wear-resistant corrosion resistance of mainshaft bushing is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: this loom mainshaft bushing, comprise the mainshaft bushing body, and described mainshaft bushing body exterior is provided with the Cr that is made by HVAF system
3C
2-NiCr cermet composite coating.
Further, described Cr
3C
2-NiCr cermet composite coating thickness is 50 ~ 700 μ m.
Further, described Cr
3C
2The porosity ratio of-NiCr cermet composite coating is 1% ~ 2%.
Compared with prior art, usefulness of the present invention is: this loom mainshaft bushing is take the low carbon steel of cheapness as body material, at the outer wear-resistant plasma sprayed coating of one deck of making of transmission shaft, not only guaranteed the abrasion resistance properties of transmission shaft but also effectively reduced manufacture cost and manufacturing efficiency has also improved greatly.
