The difference between a ball screw lift and a trapezoidal screw lift

The working principle of the ball screw: According to the national standard GB/T17587.3-1998 and application examples, the ball screw (currently has replaced the trapezoidal screw, commonly known as the Lead Screw) is used to convert the rotary motion into a Linear Motion; The linear motion is transformed into the actuator of the rotary motion, and has the characteristics of high transmission efficiency and accurate positioning. When the lead screw is used as the active body, the nut will be converted into a linear motion with the lead angle of the screw according to the rotation angle of the corresponding specification. It can be connected by a nut seat and a nut, so that there are some differences between the application of the corresponding linear motion ball screw and the lead screw. Original equipment manufacturers' applications often require "appropriate" products, and lead screws are often the right choice.

Trapezoidal screw products are easily adapted to specific applications to achieve the desired performance while keeping costs to a minimum. In some cases, life testing is required during the design phase, but for original equipment manufacturers, doing this extra work in the early stages can help reduce product costs. Ball screws can run continuously, withstand much higher loads and achieve faster speeds, and it is worthwhile to increase costs.

For the end user, the ball screw has good predictability and is therefore the best choice for fast integration and reliability. For example, factory automation systems rely heavily on ball screw technology. Of course, there are many original equipment manufacturer application systems that also require ball screws, such as the machine tool industry. For original equipment manufacturers, the technology is determined by performance and cost, not predictability.
