A propulsion shaft is a part of a system that generates thrust for a boat, 船舶或驳船, 让它们在水中移动, 也称为船用推进. 船用推进采用推力块, 位于主轴的前端, with the shaft line that incorporates all the components to move the vessel. These components include the propulsion shaft, which is used in conjunction with the tail shaft, 中间轴, 推力轴, 法兰连接, 齿轮箱, 船用引擎组件, 螺旋桨轴, propeller and bearings that hold the shaft's alignment.

海洋 shafts are subjected to many loading types during use, 包括转矩, 弯曲, 轴推力和横向载荷. 除了负荷压力, weather and sea conditions create corrosion and wear and tear, 减少推进轴的使用寿命. All of these reasons are why the requirements are so severe for these types of forgings; many "simple" parts play a critical role in not only performance but also crew safety, which is why finding a reliable partner for manufacturing these critical parts is essential.
锻造经验 & 能力:船舶,潜艇 & 船轴锻件
在苏格兰人打造, we know working to regulations for marine applications costs time and money. We can offer you a seasoned partner who comprehends the different processes to meet safety requirements and can help minimize this cost, while mitigating the risk of not meeting requirements. We have extensive experience forging 螺旋桨轴s in many diameters exceeding lengths of 75 feet (22-meter shafts), dependent on the application and overall dimensions required. We supply marine propulsion components for superyachts, 游轮, 潜艇, 海军舰艇和巡逻舰艇. We commonly produce shafts using C45, 34CrNiMo6, 不锈钢, 铬镍铁合金 甚至可以创造 定制材料 to meet specifications - in forged surface, rough machined and fully machined finishes, if needed.
