Embodiment Construction

[0016] The technical solutions of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: see figure 1 and 2 As shown in the figure, a hollow shaft sleeve for a drive shaft of an SUV passenger car has a hollow cylindrical structure and is provided with an inner hole 1, an open end 4 and a closed end 3. The depth of the inner hole 1 reaches 180mm, and the inner cavity is a spline 2 structure. , the depth reaches 180mm, which is mainly used in passenger car steering system. see image 3 As shown in the figure, the production process includes the following steps: (1) cutting material: use a circular sawing machine to cut out the metal bar according to the drawing; (2) shot blasting: the prepared billet is shot blasted to remove the oxide scale on the surface; (3) graphite coating: the billet is Heating to 220°C±20°C, and then coating the surface with dilute graphite to prevent decarbu
