Bearings play a crucial role in mechanical systems, especially in transmission applications. However, during installation and maintenance, achieving the proper fit between the bearing and the shaft can be challenging. Traditional methods such as using external pressure, flame heating, or even manual tapping with a hammer are often employed. These techniques can lead to damage, increased noise, reduced lifespan, and high energy consumption, along with significant physical strain on workers. To address these issues, the factory has developed the YG51-DKQ-I~V full-function CNC bearing heater, which is a groundbreaking solution in the field of bearing technology. This device is designed for bearings with inner diameters ranging from 115mm to 200mm, making it suitable for a wide range of industrial applications. The machine utilizes the principle of eddy current heating combined with a large current in a transformer's short-circuit ring. It incorporates advanced European and American technology, high-precision temperature sensors, and an electronic numerical control display. By applying the principle of thermal expansion, it ensures accurate and smooth installation of the bearing and shaft, based on pre-set parameters. **Key Features:** - **Main Unit Components:** The device includes a power transformer, movable iron core (matching unit), temperature actuator, and an electronic digital display. - **Operation Steps:** 1. Refer to the parameter selection table to determine the required heating temperature based on the bearing and shaft fit. 2. Select the appropriate core column according to the bearing's inner diameter. Position the moving iron core on the heater panel, place the bearing on the core, and push the panel together to form a closed magnetic circuit. 3. Adjust the power switch to the correct position, connect the power supply, and heat the bearing within 30 seconds to 3 minutes depending on its size. 4. Insert the temperature sensor into the socket on the base and place the sensor head inside the bearing or bushing. Press the bearing onto the sensor and the workbench for accurate temperature readings. 5. Turn on the digital temperature controller and monitor the heating process. When the desired temperature is reached, cut off the power, remove the iron core, take out the heated bearing, and install the shaft. **Important Notes:** - The heater warms up quickly. After turning on the power, closely monitor the temperature display. Once the set temperature is reached, immediately turn off the power to prevent damage to the bearing's microstructure. - After use, store the temperature display properly to avoid damage and ensure all power sources are turned off. - Handle heated bearings with care to avoid burns. This advanced CNC bearing heater significantly improves efficiency, reduces labor intensity, and enhances the accuracy of bearing installation, making it an essential tool in modern mechanical maintenance and repair.
