What are the common mechanical failures and solutions for brushless motor motor automatic rotor shafting machine?
The following is a brushless motor motor automatic rotor into the shaft machine common mechanical failure and the corresponding solution:
First, the transmission components failure
Failure phenomenon:
Conveyor belt failure: the conveyor belt may slip, run off or break. Slipping will lead to unstable rotor transfer speed, affecting the rhythm and accuracy of the shaft; run off will make the rotor can not accurately reach the position of the shaft; and fracture will directly lead to equipment stop running.
Chain transmission failure: the chain may be loose, jump teeth or fall off. Chain loosening will reduce the transmission precision, tooth skipping may cause inaccurate position of the rotor into the shaft, and shedding will prevent the equipment from normal operation.
Solution:
For conveyor belt failure:
If there is slipping, check the tensioning device of the conveyor belt and adjust its tension to make it reach the proper tightness. If the surface of the belt is badly worn, replace the belt with a new one, and make sure that the type and specification of the belt matches the equipment.
When the conveyor belt runs out of alignment, check the guiding devices of the conveyor belt, such as rollers, guide rails, etc., and adjust their positions to bring the conveyor belt back to the correct running track. If the deviation is caused by the inconsistency of the elasticity of the two sides of the belt, the tensioning device can be fine-tuned to make it balanced.
If the conveyor belt breaks, you need to replace it with a new one and check whether the tensioning and driving parts of the conveyor device are normal, so as to avoid breakage again.
For chain drive failure:
When the chain is loose, adjust the chain tensioner to tension the chain to the proper level.
The phenomenon of jumping teeth may be caused by chain wear or sprocket wear, check the wear of chain and sprocket, for the chain or sprocket with serious wear, the corresponding parts need to be replaced.
When the chain falls off, reinstall the chain to the sprocket first, check whether the connection of the chain is firm or not, make sure the length of the chain is suitable, adjust the length of the chain or replace the damaged chain links if necessary.
Second, into the shaft mechanism failure
Failure phenomenon:
Wear or damage of the shaft entry tool (such as press-fit head, fixture, etc.): it will result in the shaft or rotor not being firmly grasped when entering the shaft or not being able to accurately press the shaft into the rotor, thus affecting the quality and efficiency of the shaft entry.
Stagnation of moving parts of the shaft insertion mechanism: If the guide rail, slider, cylinder or hydraulic cylinder of the shaft insertion mechanism is stagnant, the shaft insertion action will not be smooth, or even the shaft insertion operation cannot be completed.
Solution:
For the problem of the shaft-in tool:
Regularly check the wear and tear of the shaft entry tool, and if it is found to be worn or damaged, promptly replace it with a new one. For the press fitting head, make sure its surface hardness and shape meet the requirements. For the fixture, check whether its clamping force is sufficient, and adjust the clamping force according to the different requirements of shaft entry or replace the fixture with a suitable one.
In daily use, lubricate and maintain the shafting tools to prolong their service life.
For the problem of stagnation of the moving parts of the shaft-entry mechanism, first clean the debris around the moving parts:
First clean the debris and oil around the moving parts and check if there are any foreign objects obstructing their movement.
Check the lubrication of the moving parts, add appropriate amount of lubricant or grease to ensure good lubrication of the moving parts. If the moving parts of the guide rail, slider and other parts of the moving parts are seriously worn, resulting in too large a fit gap, you need to replace the worn parts to ensure the precision of the fit between the moving parts.
Third, silo failure
Failure phenomenon:
Silo clogging: rotor or shaft in the silo pile up, can not smoothly enter the shaft into the process, may be due to the silo structure is unreasonable, irregular shape of the material or the material extrusion of each other.
Silo discharging mechanism failure: such as the silo's gate can not be opened or closed poorly, resulting in the rotor or shaft can not be discharged normally.
Solution:
For silo blockage:
First stop the equipment, manually clean up the blocked material in the silo. The structure of the silo can be optimized, such as adjusting the inclination angle of the silo, adding vibration devices or stirring devices to prevent the accumulation of materials.
For irregularly shaped materials, you can consider organizing the materials or using special silo design so that the materials can flow more smoothly.
For bin discharge mechanism failure:
Check the driving parts of the gate, such as cylinder, electric actuator, etc. If there is a failure, check whether its power supply and control signal are normal, and repair or replace the damaged driving parts.
Check the mechanical structure of the gate, such as the guide rail of the gate, connecting rod, etc., to ensure that it can open and close normally, repair or replace the worn or damaged parts to ensure the normal work of the gate.
Fourth, the mechanical connection parts failure
Failure phenomenon:
Loosening or falling off of connecting bolts: During the long-term operation of the equipment, the bolts of the mechanical connecting parts may loosen due to vibration, affecting the stability and precision of the equipment, and seriously leading to component displacement or even damage.
Deformation or damage of connecting parts: such as bracket, frame and other connecting parts may be deformed or damaged due to excessive force or long-term stress, affecting the overall structure and function of the equipment.
Solution:
For loose or detached connection bolts:
Regularly inspect the equipment, use tools such as wrenches to check and tighten the bolts, and for the bolts in critical parts, prevent loosening by using anti-loosening nuts or adding spring washers.
If the bolts are found to have fallen off, first find suitable bolts to reinstall them, and at the same time check whether the loosening causes problems with other parts, such as whether the relative positions of the parts are shifted, and readjust and recalibrate the equipment.
For deformed or damaged connecting parts:
Repair or replace the deformed connecting parts. For important parts such as brackets and frames, they need to be repaired or replaced with new parts of the same specifications according to the strength requirements of the equipment.
In the design and installation of the equipment, it is necessary to ensure that the strength of the connecting parts is sufficient, and the force is reasonably distributed to avoid damage to the connecting parts due to uneven force.
By identifying and dealing with these common mechanical failures, you can effectively maintain the normal operation of the brushless motor motor automatic rotor into the shaft machine, improve the reliability and productivity of the equipment, and reduce the downtime caused by mechanical failures.
