Transmission Input Shaft

Shrink Fitting: The gear is heated to thermally expand its inner bore and then fitted onto the shaft. After cooling, it contracts to form a strong interference connection.

High-precision Interference Assembly of Gear and Shaft

Induction Heating Gear Shrink Fitting Process

Reliable Force Control: A high holding force is required during press-fitting to guarantee the stability of the interference fit. The high-precision force sensors and closed-loop control system supplied by SYSTENCE monitor the press-fitting force and force variation in real time, precisely regulating the holding force within the specified range. It prevents component damage or insecure assembly caused by abnormal force values and extends the service life of products.

Higher Efficiency: Conventional presses adopt step-by-step single-process operations with cumbersome workflows and low productivity. The RX synchronous press enables multi-action coordination. Clamping, gear meshing alignment, press-fitting and inspection proceed simultaneously, greatly shortening cycle time and boosting production efficiency, to meet the large-scale and high-efficiency production requirements of SAIC transmissions.

Superior Precision: Compared with conventional processes, PROMESS RX synchronous control technology enables triple precision control of angle, displacement and force. Especially for the timing angle consistency of four gears, its control accuracy far exceeds common industry standards, effectively solving the pain points of large angular deviation and high assembly reject rate in traditional processes.
