提出了一种替代激光焊接或螺栓连接的传动系统装配新技术-滚花压装（MKPF）。这种连接方法涉及两个配合表面的压配合，一个表面带有滚花齿，另一个表面由相对较软的材料制成，使其能够在齿上流动，从而形成连接。该方法已应用于汽车后桥差速器，这是受到随机扭矩载荷。实验分析和模拟已被用来评估的可用性和潜在的好处，轧机滚花接头激光焊接和螺栓连接目前使用的宝马。假设，如总成本的规划，研究和开发，总投资，总的特定资源，原材料和制造成本被用来评估轧机滚花作为一种替代激光焊接和螺栓组件。MKPF方法已成功应用于将后桥差速器壳组装到锥齿轮上。与激光焊接和螺栓连接的竞争方法相比，其成本、重量和尺寸估计非常有利。值得注意的重量减轻将加强汽车行业减少车辆排放水平的努力。需要进一步研究对锥齿轮的寿命周期工作至关重要的节距齿面偏差值，以获得与激光焊接相当的结果。
A novel technique for drivetrain assembly - Mill-Knurling and Press-Fitting (MKPF) is projected as a substitute to laser welding or bolting. This joining practice involves the press fitting of two mating surfaces, one with millknurled teeth and the other which is of a comparatively softer material, enabling it to stream over the teeth making a joint. This process has been applied within an automobile rear axle differential which is subjected to random torque loads. Experimental analysis and simulation has been used to evaluate the serviceable viability and the latent benefits of mill knurled joints with both laser welded and bolted joints currently used by BMW. Assumptions such as total cost of planning, research and development, total investment, total specific resources, raw material and manufacturing costs were used to evaluate mill knurling as an alternative to laser welding and bolted assemblies. The MKPF method has been successfully applied to assemble rear axle differential cases to the bevel gears. The costs, weight and size estimations are very positive in comparison to the competitive methods of laser welding and bolting. The noteworthy weight saving will strengthen the efforts by the automotive industry to reduce the emission levels of vehicles. The pitch flank deviation values which are critical for the life cycle duty of the bevel gear need to be further investigated in order to achieve comparable results with laser welding.
