The intake pressure of the grease gun is insufficient

It is necessary to ensure reliable lubrication without causing waste of grease. When connecting, clean the connecting parts and tighten the nut with a wrench to avoid oil leakage. 

Filling with grease is not suitable. To The occasional customer feedback that the oil can't be added, is it really a problem with the cross shaft assembly? Before answering this question, let us first troubleshoot and solve a few problems: Whether the oil filling hole is blocked. Liyan universal joint shaft cross shaft assembly generally uses 3# general lithium grease grease, which is used in various mechanical equipment within the working temperature range of -20℃-120℃.

The intake pressure of the grease gun is insufficient. First check the above situations one by one, and I believe that most of the problems you encounter can be solved.. For the SWC350 cross shaft assembly mentioned in the article, the bearing cavity is filled with oil, and the contract is 6. The working principle of lubricating grease is: the thickening agent keeps the oil in the position where it needs to be lubricated, and when there is a load, the thickening agent releases the oil to play a lubricating effect. 

Why is it said that in some cases, workers will make a misjudgment that they can't get in the CV Joint oil? For example, the oil delivery rate of a common pneumatic high-pressure oil injection machine is about 0. Liyan Wanxiang reminds you that you must keep the interface around the interface clean during the replacement process to prevent the mixing of mechanical impurities, dust and sand.85L/min.8 MPa. 

When you encounter the problem of refueling again, you do not need to panic to determine that the structure cannot be refueled and use the violent method to refuel the grease. If the customer’s actual use of on-site temperature control is more extreme, in the early stage selection or quotation, you should communicate with the technical personnel of Liyan universal joint shaft in time

The disadvantage of this method is that the calculation is more complicated

What are the main methods for aligning the coupling? Precision machines and high-speed machines for precise alignment. It is generally used in small and medium-sized machines with rolling bearings and small axial movement.

Generally used for machines with low speed and low precision requirements.Coupling is a commonly used linkage device in the high-speed production process. Rectify. Once the center of the coupling is not found, it will affect the normal operation of the machine. It is a relatively important task to find the center of the coupling rotating equipment. 

This method has high accuracy and is suitable for needs. The correct data of the coupling is an important matter related to the high-speed operation of the machine.CV Joint . 

The outer circle double table method Using two dial gauges to measure the outer circle, the principle is to determine the relative position of the two axes through two sets of outer circle measurement readings separated by a certain distance, so as to know the adjustment amount and adjustment direction, so as to achieve the purpose of alignment. 

The disadvantage of this method is that the calculation is more complicated. The wrong method of aligning will result in inaccurate data, which will seriously affect the normal operation of the equipment, so it is an extremely strict matter to find the data of the coupling equipment.

The mandrel of the puller should be smaller than the shaft diameter

Confirm the China Drive Shaft manufacturers position of the jaws. What we need to advise you is that we must maintain regular maintenance on the use of the coupling, so as to ensure the connection The service life of the shaft. Clamp the coupling and tighten the screws to keep the level and verticality of the puller and the workpiece. According to the diameter of the shaft to be dismantled, choose different chuck pullers.

The mandrel of the puller should be smaller than the shaft diameter. Slowly move forward during operation, do not use excessive force to prevent damage to the puller. Use a wrench to clamp the bottom of the coupling, and use a copper rod to knock the other end of the straight rod to impact the coupling. For those who are not so skilled, what should we do when disassembling the jaws of the coupling? 

Here is how to use puller or other tools to disassemble: To How to remove the coupling jaws on the motor shaft with tools? 1. Hold the positioning wrench with one hand and tighten the screw with the other to enter the disassembly procedure. 4.Generally speaking, professional personnel are required to disassemble the jaws of the coupling. At this time, loosen the screws and lower the position of the jaws above the coupling.

 Finally, you can gently pull out the coupling, find the straight rod and the heavy hammer, use a wrench and a copper rod to use the lever to push the coupling out  When the coupling is almost knocked out, prevent the parts from being ejected, stop knocking with the copper rod, and easily loosen the coupling by hand. It should be noted that certain protective safety measures must be taken during operation, so as to ensure our own safety

The tooth thickness is relatively thin

First, the hob is cut radially to the gear According to the specified full tooth depth, according to the actual measured tooth thickness allowance, the hob is made to feed the same amount of left and right tangential cutting, and the result reaches the tooth thickness required by the drawing. The general processing method for internal teeth is to use standard tooth shaper cutters to cut to the full tooth depth with a radial cutting method and ensure the tooth root circle tolerance requirements. 

Because the internal teeth of this drum-shaped gear coupling have a certain amount of tangential displacement, the tooth thickness is relatively thin. In order to improve the load-carrying capacity and service life of the drum-shaped gear coupling, a short tooth profile can be adopted, and the conclusion that the addendum height coefficient is Wholesale CV Joint part manufacturers equal to the root bending strength of the internal and external gears is obtained through optimization calculation.Generally speaking, the bending strength of the tooth root of the external gear of the drum-shaped gear coupling is lower than that of the tooth root of the internal gear, so the external teeth tend to wear and break before the internal teeth. In single-piece and small batch production, the standard hob can also be used for machining with the left and right cutting method.

At this time, the workpiece should be relatively rotated a certain angle when the slotting tool does not rotate, and then continue slotting . In order to ensure that the internal and external gears have good stability during operation, most of the external tooth tip circle and internal tooth root circle are used as the centering reference, and the internal tooth root circle accuracy is ITS. The tooth thickness is still greater than the size requirement, and further slotting is required, but the root circle size has reached the required value, so the tool cannot be fed again. Although this method can be used in general gear manufacturers, the operation is complicated and the efficiency is low, and it is easy to cause tooth profile errors and affect the tooth profile accuracy. 

The internal tooth processing can be carried out by the method of tangential cutting through the knife. To Introduction to the correlation coefficients of the internal and external gears of the drum gear coupling To The internal and external teeth can be processed with a special short-tooth hob or gear shaper. It is not an ideal processing method. When the drum-shaped gear coupling adopts a special short-thick tooth profile, due to the appropriate increase of the outer gear tooth thickness, the bending strength of the inner and outer gear teeth is close, the load-bearing capacity is increased, the service life is prolonged, and the processing technology is good

There may be errors in the tooth making

The size of the workpiece blank is incorrect. When hobbing helical gears, the additional movement direction is wrong Increase or decrease the intermediate wheel in the differential exchange gear. 

Re-adjust the span wheels, exchange the gears by dividing teeth, and check whether the intermediate wheel device is correct. If the number of teeth is correct, but the number of teeth is incorrect after the tooth is made, it is also possible that there are many Inner CV Joint manufacturers reasons. Change the blank. 

This is a more important issue. Sometimes if the calculation is incorrect, there may be errors in the tooth making. Incorrect adjustment of span wheel or split tooth exchange gear. Use hobs reasonably. Wrong hob selection. What problems will occur in the processing of the drum gear coupling teeth? How to solve it? What problems will occur in the processing of drum gear coupling teeth? 

There are many issues to consider when processing the teeth of drum gear couplings, such as the quality of the gears, what problems have occurred, what are the main reasons, and how to solve them. We have to tell the number of teeth and modulus before making the tooth.

Does it mean that universal joint shaft parts are not universal?

But from the picture, the cardan shaft is not manufactured by our company, so There may be some difficulties in the practicality of parts. Customer first is important. To put it aside, it is not right that there is no qualified paint solution for the shape of the universal joint shaft. There is no problem with the right. It is on the spot in your production workshop. 

The quality of cardan shafts should be a production system with complete steps, only paying attention to a few points, and it is not advisable without overall quality awareness. Specifically, it is more serious to the left.There is an abnormal noise when the universal joint is operating. Everyone will comprehensively consider and come up with an effective plan. It is recommended to shut down and disassemble the universal joint shaft and check whether the cross shaft assembly is Wholesale Inner CV Joint intact, whether the roller bearing is deformed by extrusion, whether the fork is cracked, remove dirt, and check for hidden safety hazards. 

Although manufacturing is critical, safety should come first. Does it mean that universal joint shaft parts are not universal? What is the quality of the universal joint shafts produced by everyone? If you want to buy a new cardan shaft, what are the main parameters? For this type of SWC type overall fork cross shaft universal coupling, the national standard number is JB/T5513. What's the matter? From the video shooting alone, it should be that the cross shaft assembly on one side is broken, and the roller bearing is worn out, which causes the installation gap of the cross shaft assembly to increase, and the abnormal noise caused by the assembly shaking inside the rolling bearing hole . 

Furthermore, when it comes to this universal joint shaft, there is a reason for it to cause abnormal noise.. If there is indeed a request to purchase a new cardan shaft, you can show the necessary connection specifications to facilitate everyone to check the specifications and models. After all, there are differences in the production and manufacturing technology, technical research and development capabilities, and the actual operating level of employees
