Lightweight cam bearing cover structure

According to a light-weight cam bearing cover structure provided by the invention, material removal processing is carried out on a part, which can generate stress concentration, of a bearing cover, and chamfering processing is carried out on the edge part of each structure of the part, so that the loading working condition of a specific diesel engine can be met by adopting a low-strength processing material, and the light weight of the target diesel engine can be well realized on the premise of ensuring the working stability. According to the light-weight cam bearing cover structure, an original structure is improved, the local stress concentration phenomenon of the bearing cover is effectively reduced, on the premise that the low-strength materials are adopted, the practicability and reliability of an existing bearing cover are improved, and on the premise that the cost is low and machining is easy, the difficulty in the prior art is well solved. 本发明提供了一种轻量化的凸轮轴承盖结构，通过对轴承盖会产生应力集中部分进行去除材料加工，并对该零件各结构边缘部分进行倒圆角处
