Problems solved by technology

However, this semi-circular pin hole is not conducive to the smooth rolling of the pin tooth pin, which will increase the friction of the pin tooth pin meshing transmission, which will increase the wear and temperature rise of the pin tooth pin, so that it will affect the life of the reducer.
