Abstract
The invention discloses a wear resisting cam shaft and a manufacturing method. The cam shaft adopts a material of a light wear resisting magnesiumalloy; the light wear resisting magnesiumalloy comprises the following components in percentage by mass: 5-10% of aluminum, 1-5% of zinc, 0.1-0.6% of silicon, 0.5-0.9% of copper, 0.7-1.2% of nickel, 0.2-0.5% of iron, and the balance of magnesium; and the manufacturing method of the cam shaft comprises the following steps: (a) a light wear resisting magnesium alloy cam shaft blank is turned, milled and finished; (b) the surface of the finished cam shaft is treated; and (c) the flow detection, the demagnetization and the warehousing are performed. Through the mode, the manufacturing process is simple; and the prepared cam shaft has such advantages as low rotating inertia, good wear resistance and long service life.
Description
technical field [0001] The invention relates to the technical field of knitting camshaftprocessing, in particular to a wear-resistant camshaft and a manufacturing method thereof. Background technique [0002] During the knitting process of the warp knittingmachine, in order to complete the lapping, the bar must move laterally along the needle bed before and after the needles in addition to swinging between the needles. The function of the bar traversing mechanism is to make the bar complete the traversing motion according to certain requirements. The transverse movement of the bar determines the distribution of the loops formed by the warp yarns of the bar in the fabric, and several combinations of the transverse movement of the bar form a certain organizational structure and produce the required fabric pattern. [0003] Cam-type bar traverse mechanism is a kind of traverse mechanism of warp knittingmachine, which is widely used on high-speed warp knittingmachine. The ...
