Welcome to today's video presentation! In this session, we'll highlight the ROCHO Induction Heating Shrink Fit System, meticulously crafted for the automated heating of metal components such as motor stators, rotors, housing, bearings, bolts, and more. Explore the advantages of employing this cutting-edge machine and discover how it can elevate your production efficiency. Stay tuned for valuable insights!



Motor rotor shrink fitting involves heat exchange with bearings. As the rotor heats up during motor operation, due to current flow and mechanical friction, bearings support it for thermal balance through coupling.

This process, aided by the bearing and lubrication system, ensures efficient heat dissipation, preventing overheating issues and improving motor performance and lifespan.

In shrink fitting, precise temperature control is crucial to prevent performance decline and axial displacement. Accurate temperature management in processes like heating motor bearings and thermal sleeves ensures efficient and accurate shrink fitting.

In the shrink fitting process, precise temperature control is crucial. Elevated temperatures can lead to a decline in component performance. Simultaneously, it is essential to accurately control the optimal time for fitting to prevent issues like axial displacement.

By precisely managing temperatures, such as heating for large motor bearings or thermal sleeves for motor housings and stator cores, shrink fitting becomes more efficient and accurate. This video will provide a detailed guide on effectively mastering these key elements during the operation, ensuring the smooth progress of motor rotor shrink fitting.

Our company offers a complete set of automated multi-station shrink fitting equipment with integrated design, covering processes such as loading, heating, assembly, cooling, and retrieval.  Featuring a modular design for precise positioning and high-precision servo cylinders for accurate pressing, our system enables unmanned production. Remote intelligent monitoring ensures efficient and precise assembly.

We proudly introduce our company's independently developed high-precision digital high-frequency induction heating equipment. Utilizing electromagnetic induction heating technology, it provides precise control and rapid heating, making it ideal for heat shrink fitting.

Heat can be concentrated locally, affecting only the area around the adjacent surface, which is advantageous when heating large components, saving energy as the entire part doesn't need heating. It also helps prevent deformation and cracking caused by repeated heating and cooling, making induction suitable for components requiring frequent disassembly and reassembly.

The fast heating time maximizes production efficiency, and the induction process ensures consistent and reproducible results, achieving uniform heating of the stator casing for an optimal expansion effect, enhancing the stability of the assembly process.

In the future, motor rotor shrink fitting technology will see more innovations and improvements.
If you're seeking a fully automatic, precise, and efficient induction heating machine for shrink fitting, ROCHO is your perfect solution. Thank you for your attention, and we look forward to staying connected with you!
