Reasons and maintenance of noise generated by NEXEN Nixon gearbox

When there is a problem with the gearbox, it is often due to gear meshing. When such a problem occurs, the solution is as follows:

To avoid tooth tip interference during gear meshing, consciously trim the tooth profile near the tooth tip.

The purpose of tooth profile modification is to achieve smooth meshing of gear teeth, similar to the grinding process in the direction of tooth profile.

In addition, there may also be problems with the gearbox body or other braking equipment. The solutions are as follows:

1. Gearboxes are often located in narrow environments and require the addition of low-temperature and anti brittle coagulants;

2. Add components to prevent vibration and impact during maintenance;

3. Increase lubricants to ensure sufficient lubrication conditions;

4. For areas with significant temperature differences between winter and summer, appropriate heating and cooling equipment should be installed, including anticoagulants, heaters, and so on.

In some cases, couplings can also serve as a safety device to prevent the connected components from bearing excessive loads and provide overload protection.

Coupling refers to a device that connects two shafts or shafts with rotating parts, rotates together during the transmission of motion and power, and does not detach under normal circumstances. The main function of a coupling is to firmly connect the active and driven shafts in different mechanisms, rotate together, and transmit motion and torque. In addition, couplings can also serve as a safety device to prevent the connected components from bearing excessive loads and provide overload protection.

The maintenance methods for couplings mainly include installation, maintenance, and troubleshooting, as follows:

1. Installation points:

a. Before installation, it is necessary to carefully check whether all components of the coupling are complete and undamaged.

b. Determine the position of the shaft end, indicate the installation position of the coupling, and check the forward and reverse direction of the coupling.

c. Lubricate the shaft hole and use lubricating oil to shorten installation time and avoid wear.

d. Tighten and secure the various components of the coupling to prevent movement. If there is significant looseness, it should be removed and re tightened.

e. After installation, confirm that the rotor is functioning properly, the coupling is lightweight, and there is no obvious vibration or oscillation.

2. Maintenance points:

a. Regularly inspect the coupling to ensure that all components are functioning properly, free from looseness, cracks, etc. If wear or damage is found, it should be replaced in a timely manner.

b. Maintenance and lubrication are key, and it is necessary to lubricate according to the recommended lubrication cycle and method, and check whether the lubricating oil is smooth or reaches the lubricated parts.

c. Regularly clean the coupling to remove impurities and deposits to ensure its functionality and performance.

d. Regularly monitor the operation of the coupling, and if any abnormalities are found, stop the machine for inspection and maintenance.

e. During use, the coupling should be avoided in environments that are too humid, dusty, and subject to high vibrations.

3. Fault handling:

a. For the wear of the coupling shaft head, Sorel carbon nano polymer material technology can be used for repair. This technology is simple and easy to operate, does not require secondary processing of the repair surface, and will not affect the material and structure of the equipment itself.

b. Repair materials have good bonding properties. Through surface oil baking, surface polishing, anhydrous ethanol cleaning and other treatments, the surface bonding area and bonding force of the material are increased to ensure that the material will not fall off.

c. To solve coupling faults, it is necessary to comprehensively consider various factors such as installation, load, quality, and maintenance. Establish an equipment management system, clarify the operational procedures for equipment inspection, maintenance, upkeep, and replacement, improve equipment management efficiency, and reduce the risk of coupling failures.

d. By adopting modern state monitoring and fault diagnosis technology, the operating status of the coupling can be monitored in real time. Once any abnormal situation is detected, corresponding measures should be taken immediately to prevent the fault from escalating.

Gearbox problem:

1. In terms of gear design. Improper parameter selection, too small overlap, improper or no tooth profile modification, unreasonable gearbox structure, etc. Excessive pitch and tooth profile errors, excessive tooth flank clearance, and rough surface in gear machining.

2. In terms of gear system and gearbox. Assembly eccentricity, low contact accuracy, poor parallelism of the shaft, insufficient stiffness of the shaft, bearings, and supports, low rotational accuracy of the bearings, and improper clearance.

3. Input torque in other aspects. Fluctuations in load torque, torsional vibration of the shaft system, balance of the electric motor and other transmission pairs, etc.

The braking torque gradually decreases, the brake wheel temperature is too high, the brake cannot be opened, it is easy to disengage from the adjusted position, the brake is overheated, the brake noise is too loud, the brake leaks oil, the brake does not work, the braking effect is poor, the brake is overheated, the brake leaks oil, and the brake noise is too loud.

The specific manifestations and possible causes of these faults are as follows:

The braking torque gradually decreases: it may be due to brake pad wear, brake spring breakage, or improper adjustment.

Brake wheel temperature is too high: it may be due to overuse, excessive wear of brake pads, or insufficient lubrication.

The brake cannot be opened: it may be due to a malfunction of the electromagnet or a problem with the control circuit.

Easy to detach from the adjusted position: It may be due to loose mechanical structure or improper adjustment.

Brake overheating: It may be due to blockage of the brake system, resulting in poor heat dissipation, or prolonged high load operation of the brake.

Excessive brake noise: It may be due to insufficient hardness of the brake pads or foreign objects entering the brake system during the braking process.

Brake oil leakage: It may be due to damaged seals, causing oil leakage.

Brake not working: It may be due to a control circuit malfunction or damage to the brake itself.

Poor braking effect: It may be due to severe wear of the brake pads or insufficient brake fluid.

The common faults of torque limiters mainly include urea level temperature sensor faults, SCR system component faults, sensor failures, and electronic data processing and logic faults. These issues typically result in the engine control unit (ECU) limiting the engine's torque output to protect the engine from further damage.

The solutions to these faults include the following aspects:

1. Replace the urea level temperature sensor:

If the urea level temperature sensor is damaged, a new sensor needs to be replaced to ensure that the ECU can correctly monitor the urea temperature and level, thereby restoring torque output.

2. Cleaning and maintenance of SCR system:

Clean the SCR system with a suitable concentration of urea solution and purified water to ensure normal operation and relieve torque limitations.

3. Unlock using computer technology:

Industrial clutch is a mechanical device mainly used to achieve separation and connection between engine and gearbox. It can complete tasks such as starting, stopping, reversing, and shifting of the working machine by manipulating or controlling the clutch. Industrial clutches have functions such as soft start, energy saving, absorbing impact energy, reducing vibration, achieving speed overtaking, preventing reverse, and providing overload protection for the transmission system.

There are various types of industrial clutches, including pneumatic clutches, electromagnetic clutches, mechanical clutches, hydraulic clutches, magnetic powder clutches, polar friction clutches, power take-off (PTO) clutches, and multi plate clutches. Each type of clutch has its own working principle and application scenarios. For example, pneumatic clutches are controlled by compressed air for engagement and disengagement, making them suitable for situations that require quick start stop; The electromagnetic clutch relies on the power on/off of the electromagnetic coil to achieve engagement and disengagement, and is suitable for equipment that frequently starts and stops; Mechanical clutches achieve power transmission through mechanical means and are suitable for situations with light loads.
