During the long-term operation of the packaging machine, the bearing stuck of the packaging machine motor is one of the common faults. Bearing stuck can cause abnormal operation of the motor, equipment shutdown, and even damage to core components, which directly affects production efficiency. In response to this problem, I will introduce the disassembly and cleaning process of the packaging machine motor bearing stuck in detail, and provide industry-wide maintenance skills to help companies quickly restore equipment stability.
1. Fault diagnosis and preparation work
When the packaging machine motor makes abnormal noises, speed drops, or stops completely, the bearing problem must be checked first. First, cut off the power supply and disassemble the motor housing to check whether the bearing is stuck due to insufficient lubrication, dust accumulation, or rust. Before operation, you need to prepare a cleaning agent (such as industrial-grade kerosene or special solvent), a soft brush, a dust-free cloth, and conventional grease to ensure that the tools and environment are clean.
II. Bearing disassembly and cleaning steps
Bearing disassembly: Use a professional puller or heating method (medium and low temperature) to smoothly separate the bearing from the motor shaft of the packaging machine to avoid violent operation to damage the parts.
Preliminary cleaning: Use a soft brush to remove dust and oil attached to the surface of the bearing, and then soak it in a cleaning agent for 10-15 minutes to dissolve stubborn impurities.
Deep cleaning: Manually rotate the inner and outer rings of the bearing to ensure that the stains between the ball and the track are completely removed. For areas with heavy oil pollution, you can soak and brush lightly repeatedly.
Drying and inspection: After cleaning, wipe the bearing with a dust-free cloth, place it in a ventilated place to dry naturally, and then check for cracks, deformation or wear marks.
III. Lubrication and assembly specifications
The cleaned bearing needs to be evenly coated with industry-standard high-temperature grease, and the filling amount should be controlled at 1/3-1/2 of the bearing cavity to avoid excessive resistance. During assembly, the shaft and bearing hole must be aligned, and the bearing and motor shaft must be tightly fitted by tapping or slowly resetting the press. After completion, manually test the rotation flexibility, and then power on for low-load test run.
Fourth, tips for preventing the motor bearing of the packaging machine from getting stuck
Regular maintenance: It is recommended to lubricate and replenish the motor bearing of the packaging machine every 3-6 months, and shorten the cleaning cycle according to the working conditions.
Environmental control: Reduce the intrusion of dust and moisture into the motor. Protective covers can be installed around the equipment or the production environment can be cleaned regularly.
Load monitoring: Avoid long-term overload operation of the packaging machine motor, and adjust the equipment operating parameters in time to reduce bearing loss.
