Casting structure design: ensure its working performance and mechanical performance requirements, consider the requirements of casting process and alloy casting performance on casting structure, whether the casting structure design is reasonable or not has a great impact on the quality, productivity and cost of castings.
Meet the strength and stiffness requirements. For box parts with large forces, meeting the strength is an important issue; but for most boxes, the main indicator for evaluating performance is stiffness, because the stiffness of the box not only affects the normal operation of the transmission parts, but also affects the working accuracy of the components. The casting parts are included in the quick and easy automatic selection.
Heat dissipation and thermal deformation issues. The friction and heat generated by the parts in the box changes the viscosity of the lubricating oil, affecting its lubrication performance; the temperature rise causes thermal deformation of the box, especially the thermal deformation and thermal stress with uneven temperature distribution, which have a great impact on the accuracy and strength of the box.
