[0002] A lightweight crankshaft is a crankshaft with a simple design, light weight and low manufacturing cost. It is usually used in small engines and vehicle drive systems. The design and manufacture of lightweight crankshafts need to consider multiple factors, including material selection, strength and stiffness, heat treatment, processing technology and dynamic balancing, in order to achieve the goals of lightweight, high performance and high reliability.

[0003] During the use of existing light crankshafts, the driving effect is usually achieved by using multiple sets of journals together. However, the journals of light crankshafts are prone to damage after long-term use. At this time, the light crankshaft needs to be replaced. However, currently the light crankshaft needs to be replaced as a whole, and the damaged journal cannot be replaced. The cost of use is high. At present, light crankshafts are usually installed with a large number of bolts, and the installation and disassembly are relatively cumbersome, which affects the efficiency of subsequent disassembly and maintenance of the light crankshaft.
