Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0011] As shown in the figure, this embodiment can prevent the structure of the motorcycle clutch cover from nitriding deformation, including the left cover 1, the right cover 2 welded to the left cover 1, and the flower welded to the inner holes of the left cover and the right cover. As for the key cover 3, the air elimination hole 4 is arranged on the cover bottom plate of the right outer cover, and of course, the air elimination hole 4 can also be arranged on the cover bottom plate of the left outer cover in specific implementation.
[0012] After the welding of the clutch cover, the contact surfaces of the left cover 1 and the right cover 2 are sealed by welds to form a closed space. During the nitriding process, the air in this closed space expands due to heat. Air elimination holes 4 are arranged on the bottom plate, so that the inflation air can ...

The invention discloses a motorcycle clutch outer cover structure capable or preventing nitridation deformation. The motorcycle clutch outer cover structure comprises an outer left cover, an outer right cover and a splined hub, wherein the outer right cover is connected with the outer left cover in a welded manner; the splined hub is connected with inner holes of the outer left cover and the outer right cover in the welded manner; an air outlet is formed in a bottom cover plate of the outer left cover or the outer right cover. According to the motorcycle clutch outer cover structure capable or preventing nitridation deformation, after being welded, contact surfaces of the bottom cover plates of the outer left cover and the outer right cover are sealed by weld joints, so that a sealed space is formed; in the nitridation process, the air in the sealed space is heated to expand; as the air outlet is formed in the bottom cover plate of the outer right cover, the expanded air can be discharged out from the air outlet, so that the problem of the deformation of the outer covers caused by the air expansion is solved.
Description
technical field [0001] The invention relates to a clutch, in particular to an outer cover of a motorcycle clutch. Background technique [0002] Heat treatment is an important processing technology to improve product quality. After heat treatment, the material can improve the hardness and strength of the product and prolong the service life of the product. [0003] For example, the outer cover of a motorcycle clutch frequently contacts the friction block during work, so it needs to have high hardness and wear resistance, so the outer cover needs to be nitrided during the manufacturing process. However, since the nitriding treatment of the outer cover is carried out in a sealed environment, the air will expand due to heat during the nitriding process, which will cause deformation of the outer cover and affect the performance of the product. Contents of the invention [0004] In view of this, the object of the present invention is to provide a motorcycle clutch cover structu...
