Problems solved by technology
[0003] Whether it is belt drive or hydraulic drive, these are not as high precision as gears and ball screws. Among them, ball screws have good precision and high strength, but correspondingly, their production requirements are also high and expensive, so they cannot be applied to more There are many daily products, or some equipment that can improve the accuracy or user experience by installing ball screws, so as to achieve more controllable and better user experience

The high-accuracy and simple-structure type threaded pipe pair transmission is characterized by comprising an outer pipe and a threaded pipe pair. According to the high-accuracy and simple-structure type threaded pipe pair transmission part, a high-accuracy and high-strength transmission part is supplied and is applicable to various environments needing transmission mechanisms; a device or a mechanism utilizing the high-accuracy and simple-structure type threaded pipe pair transmission part can smoothly perform transmission; in addition, compared with a pneumatic spring and hydraulic transmission and other transmission mechanisms, the high-accuracy and simple-structure type threaded pipe pair transmission part is accurate in distance starting and stopping control and safety performances and is free from rod breaking and other circumstances; and the high-accuracy and simple-structure type threaded pipe pair transmission part meets the efficient, accurate and safe manufacturing and using idea in current market.
Description
technical field [0001] The invention relates to a pipe fitting, in particular to a threaded pipe pair transmission part with high precision and simple structure. Background technique [0002] Today, people's requirements for life and product quality are increasing day by day, which corresponds to the test of technology, equipment and details in the production industry. Among them, the products are inseparable from the transmission parts (transmission mechanism) from the production line to the molding sales, such as The assembly line that transmits the semi-finished products of the electric strut, where the assembly line can be driven by a belt or a chain, and the electric strut lying on the assembly line can be a hydraulic or other built-in transmission mechanism, so as to achieve its working purpose. [0003] Whether it is belt drive or hydraulic drive, these are not as high precision as gears and ball screws. Among them, ball screws have good precision and high strength, b...
