The installation assembly can quickly and conveniently install the camshaft into the sleeve, improves the installation accuracy and work efficiency, and avoids damage to the camshaft.

[0004] In the existing cam installation process, it is usually necessary to match the cam and the camshaft to each other, and the presence of bearings to prevent the wear of the camshaft and the cam. However, in the actual operation process, due to production needs, it is necessary to continuously optimize the relevant parameters and design models of the cam, so as to solve the problems of unstable cam feed and high failure rate. Therefore, it is also necessary to match the relevant installation components according to the shape and size of the cam, so as to improve the efficiency and accuracy of the installation. However, in the existing production process, the lack of this installation component can easily lead to problems in the coordination between the cam and the surrounding structure. Based on this, the utility model designs a rolled cam installation component to solve the above problems. Utility Model Content
