Cone crushers offer high productivity, low energy consumption, and a relatively uniform material particle size.
Advances in cone crusher stability are due to the application of hydraulic technology, which protects the crusher from damage caused by uncrushable materials entering the crushing chamber. Foreign matter, such as steel, can cause extensive damage to cone crushers and result in increased production costs. Advances in hydraulic relief systems have significantly reduced downtime and increased the lifespan of these machines.
What causes excessive vibration in gear reducers? What are the solutions?
1. Excessive bearing wear
When bearings operate for extended periods, excessive bearing clearance or imbalance can occur, leading to frictional heating of the bearings. The most dangerous situation is friction between the rotor and stator, which can directly damage the bearings. Sliding bearings are most susceptible to vibration because the viscosity of the lubricating oil can cause the shaft to float. This is also related to the weight of the bearings; heavier bearings tend to wear more quickly.
2. Excessive base vibration
In some cases, excessive base vibration can also have an impact. The base vibration frequency can be correlated to the gear reducer's speed, suggesting a design issue, leading to unstable operation.
3. Drive misalignment
When the alignment between the motor and driver in a gear reducer is poor, vibration can easily occur. Adjust the alignment and reinstall the driver-motor connection to stabilize the rotation of the motor bearings.
4. Mechanical rotor imbalance
Imbalance refers to both static and rotating rotor imbalance. This occurs when the rotor deviates from its axis, causing centrifugal force to cause deflection and abnormal vibration.
5. Loose rotor components
Several parts of the motor rotor, such as the commutator, magnet, and pulley, can become loose over time. This condition typically results in a noisy rotor. These issues should be addressed as soon as possible, as they can become increasingly serious over time.
In summary: Excessive vibration in gear reducers is a common problem. We're not asking you to understand any complex repairs, but rather some tips for routine maintenance and simple minor repairs. While excessive vibration may not significantly impact the reducer, long-term untreated problems can have serious consequences. The following is a summary of several causes of excessive vibration in gear reducers by the Wanguan Hardware & Machinery Network editors. This summary is for reference only.
Common Faults and Solutions: Reducers often experience wear and leakage over long periods of operation. The most common faults are:
1. Wear of the reducer bearing housing, including wear in the housing bearing box, the housing bore bearing housing, and the gearbox bearing housing.
2. Wear of the reducer gear shaft, primarily at the shaft head and keyway.
3. Wear of the reducer drive shaft bearing seat.
4. Leakage at the reducer mating surfaces.
What's wrong with the hydraulic press shaking during lifting? First, check if there's enough hydraulic oil in the tank. This can also happen if there's insufficient oil. Also, check if the oil inlet is loose. If it's loose, it can absorb air, causing unstable pressure and causing the machine to shake. Check carefully. I hope this helps.
