What is the cause of wear and tear of your dragon tooth coupling?

Reasons for the wear of gear couplings: First, the oil quantity of the lifting accessories coupling is insufficient or lacking of oil. Or improper use of grease, resulting in calcification of grease, resulting in the inability to lubricate between the tooth surface, or poor lubrication resulting in serious tooth surface wear, this situation can be avoided as long as the new grease is replaced, and qualified grease oil is regularly injected to prevent oil leakage and sufficient oil.

Second, the error of the two-axis levelness and coaxiality is too large, which exceeds the range that can be compensated by the coupling, so that the shaft teeth and the internal teeth are not meshed correctly, resulting in local contact, and additional torque appears. And this additional moment can be decomposed into axial forces. Acting on the internal gear ring, the size of this force depends on the size of the deviation, and the deviation is proportional, the greater the deviation, the greater the force, resulting in the axial displacement of the inner gear ring of the lifting accessories coupling.

If the displacement is too large, it will be uncontrollable, resulting in serious wear of the gear, and even broken teeth, and the internal and external teeth cannot be meshed until they cannot be transmitted.

The gear coupling is characterized by relying on the internal and external tooth meshing to transmit torque, which can transmit a large torque and is easy to install, but it is heavy in weight and high in cost, and is often used in medium and low-speed heavy machinery. The gear coupling material of Botou Wansheng coupling manufacturer is generally made of No. 45 steel or ZG45 cast steel.

The common faults of gear couplings are as follows:

Insufficient oil quantity or lack of oil in the coupling of lifting accessories. Or improper use of grease, resulting in calcification of grease, resulting in the inability to lubricate between the tooth surfaces, or poor lubrication resulting in serious tooth surface wear. Solution:

As long as the grease is replaced with new one, qualified grease oil is injected on a regular basis to prevent oil leakage, and the oil amount is sufficient, it can be avoided.

The tooth surface of the gear coupling is seriously damaged;

The gear ring of the gear coupling produces a large amount of axial displacement, and even cannot be meshed;

Gear coupling has a broken tooth;

The counter-bolt of the gear coupling is broken;

There are generally three lubrication methods for gear couplings:

Oil storage lubrication. The lubricating oil is injected into the nozzle, and the lubricating oil is subjected to centrifugal force when it rotates, and a certain lubricating oil layer is maintained in the outer circle of the gear. This type of lubrication will keep the magazine trapped in the ring gear, and the oil flow will be less effective at dissipating heat, so it is only suitable for applications with low power and low speed.

There is also a non-flowing oil storage lubrication method that belongs to this type, that is, the grease is poured into the interior and sealed, and it is washed and replaced regularly.

Self-flowing lubrication. The lubricating oil is injected from the nozzle, flows through the gear side clearance, and flows out of the small hole of the sleeve, which mainly plays a cooling role, and it is difficult to form an oil film, and the tooth surface wears faster than the strong lubrication described below.

Strong lubrication. The lubricating oil is sprayed from each small hole at the bottom of the tooth, and the oil enters the meshing surface by centrifugal force to lubricate and cool. The oil flows out from both sides of the tooth after passing through the meshing surface.

This type of lubrication, the oil flow is circulating, the magazine flows out, and the injected lubricating oil causes a certain pressure to enter the gear tooth meshing surface under the action of centrifugal force, so it has a good lubrication and cooling effect, and is suitable for high-speed and heavy-duty occasions.

Botou Wansheng coupling **** produces all kinds of drum tooth couplings, plum blossom couplings, elastic couplings. The company can also customize a variety of (including non-standard) couplings according to customer needs.

Gear Coupling**:

The gear coupling has a small radial size, large bearing capacity, and is long for shafting transmission under low-speed and heavy-load conditions, and high-precision and dynamically balanced gear couplings can be used for high-speed transmission, such as the shafting transmission of gas turbines. Because the angular compensation of the drum gear coupling is greater than that of the straight gear coupling, the drum gear coupling is widely used at home and abroad, and the straight gear coupling is an eliminated product, and the selector should try not to choose.

How to analyze the maintenance method of WGT type intermediate sleeve drum gear coupling? Good lubrication is a necessary guarantee for the safe and reliable operation of drum gear couplings, as well as for slowing down wear. Under the condition that the bending strength of the tooth root and the contact strength of the tooth surface are sufficient, the tooth width should be determined with a large degree of coincidence, and the tooth width should not be blindly increased, so as not to increase the structure size unnecessarily.

Generally, the tooth width factor is 8-14. The minimum tooth width should be determined by the allowable root stress, taking into account the width required for the displacement of the force point along the tooth width due to the camlination between the shafts.

An important way to improve the service life of WGT intermediate sleeve drum gear coupling. The tooth width coefficient affects the tooth root bending strength and the tooth surface contact strength of the gear teeth, the larger the tooth width coefficient, the greater the strength of these two items, the tooth width coefficient affects the degree of coincidence, when the tooth width coefficient is less than the range of a certain value, the increase of its value has a greater impact on the increase of the degree of coincidence, and when it is greater than this certain value, the increase of the device value has a smaller impact on the increase of the degree of coincidence, for the drum tooth coupling of the arc drum curve, the tooth width is still the parameter that determines the radius of the drum circle and the backlash, the larger the tooth width, the larger the radius of the drum circle, and the larger the required backlash.

Therefore, the WGT type intermediate sleeve drum tooth coupling needs the following highlight requirements: the smaller the concentrated load of a wheel tooth, the better.

Whether the wear of the coupling of the brake motor damages the motor depends on the wear of the coupling.

1. If the coupling is worn and stuck, the motor bearing will be damaged, and then if the driver protection is not enough, the motor will be damaged in time, but this situation generally does not happen.

2. If the wear of the coupling does not cause unsmooth rotation, it has no effect on the motor itself, but may affect the part after the transmission.

The flywheel does not meet the processing quality required by the drawings, the balance performance is poor, and the axial or circumferential radial runout of the end face of the flywheel is too large, so that the two planes can not be joined evenly, and the friction is uneven, so that the flywheel works in a wavy shape.

When the flywheel rotates, due to the speed difference between the clutch and the flywheel plane at the moment of separation and combination, the two slide relatively, causing the flywheel working surface to be worn. The flywheel plane can also be locally ablated and hardened by the high temperatures generated by high-speed friction.

When the flywheel rotates, due to the large torque and the impact load is often accompanied by the transmission of torque, the screw hole on the flywheel will be damaged and deformed over time.

The friction plate is worn and thinned, and the rivet head exceeds the friction plate plane, which scratches or grooves the working surface of the flywheel, or the friction plate is damaged, and the rivet is loose, causing damage to the flywheel plane.

Improper driving operation, or no free travel, or insufficient pressure of the clutch disc, so that the clutch and the flywheel are often in a semi-clutch state, which aggravates the wear of the contact surface of the flywheel.

The most likely thing is that there is a problem with your starter, but it cannot be ruled out that your vehicle often has the wrong operation of ignition during operation.

The biggest possibility is that there is a problem with your starter, that is, it did not return to the position after ignition.

However, it cannot be ruled out that your vehicle often has the wrong operation of ignition during operation or the ignition switch contact time is too long when the engine is started.

It could be the following:

First, the flywheel is deformed, the installation is unbalanced, and the loosening.

Second, the starter is not installed properly....
