Oscillating motors are commonly used in vibrating screens and other screening equipment. They generate the necessary vibration through their eccentric motion, making them a crucial component of the system. These motors typically use heavy-duty bearings that can withstand axial loads regardless of the motor's orientation. Proper maintenance and replacement of these bearings are essential for ensuring long-term performance and reliability. Here’s a step-by-step guide to replacing an oscillating motor bearing: 1. **Disassemble the Motor** - Remove the protective covers from both ends of the motor (if present). For vertical oscillating motors, there may be no cover. - Record the excitation force setting before disassembly to ensure it can be restored later. - Remove the Shaft retaining rings at both ends. - Loosen the outer bolts and remove the outer bearing block. Take out the key from the shaft. - Loosen the inner bolt and remove the inner bearing block. - Remove the bearing housing by loosening the compression bolt and using a suitable bolt to push it out. - Extract the bearing from the housing using a suitable tool or by pushing it out. - If the bearing is a separable cylindrical roller type, remove the inner race from the shaft and place it back into the original housing. - Clean all parts thoroughly and remove any remaining oil. 2. **Install the New Bearing** - Ensure the new bearing matches the original in type and specification. - Clean the bearing with kerosene and press it into the bearing seat. - Fill two-thirds of the outer ring housing with Shell No. 3 lithium-based grease, ensuring even distribution. - Install the bearing gland and secure it with anti-loose rubber washers. - If the bearing is a separable cylindrical roller type, position it correctly on the rotating shaft. - Mount the bearing housing onto the casing and align the grease fitting if present. - Secure the bearing seat with the anti-loose bolt. - Reinstall the bearing block onto the shaft, insert the key if needed, and fit the retaining ring. - Tighten the fastening bolts and adjust the bearing block to the correct position before tightening. - Ensure the shaft has some axial movement after assembly. - Reattach the protective covers on both ends and secure them with screws. By following these steps, you can effectively replace the bearings in an oscillating motor, ensuring smooth operation and extending the motor’s lifespan. **Related Bearing Knowledge** - Bearing Application and Protection - SKF Bearings: Interference Fit Considerations - 10 Ways to Distinguish Genuine FAG Bearings - Understanding Magnetic Bearings This article is sourced from China Bearing Network.
