High-strength wear-resistant cam shaft

The invention discloses a high-strength wear-resistant cam shaft which comprises a core shaft, a cam shaft, a cam shaft and a cam shaft, the mandrel is coated with a high-strength coating; and the exhaust cam and the air inlet cam are further coated with wear-resistant coatings. The camshaft is coated with the high-strength coating, the strength of the mandrel is enhanced, meanwhile, the air inlet cam and the exhaust cam are coated with the wear-resistant coatings, the wear resistance is improved, and the trouble that an existing camshaft is poor in wear-resistant effect and low in durability is avoided. 本发明公开了一种高强度耐磨凸轮轴，其包括：芯轴，芯轴设置有排气凸轮和进气凸轮；芯轴涂覆高强度涂层；排气凸轮和进气凸轮进一步涂覆有耐磨涂层。本发明通过在凸轮轴上涂覆高强度涂层，增强芯轴强度，同时在进气凸轮和排气凸轮上涂覆耐磨涂层，提高耐磨性，避免以往凸轮轴耐磨效果不好，耐用性低的麻烦。
