Furthermore, the torque transmission blocks are independent modules; their pin holes are machined simultaneously when processing four blocks, ensuring coaxiality between any two connected blocks. Locating pins on the torque transmission blocks ensure accurate positioning when connected to the flange. Additionally, solid lubrication sleeves are installed within the pin holes of the torque transmission blocks to reduce wear during use.
