The structure and principle of automobile transmission shaft
The drive shaft is an important part of the transmission system of the automobile for transmitting power. Its function is to transmit the power of the engine to the wheels together with the gearbox and the drive axle, so that the car can generate driving force. Special automobile drive shafts are mainly used in vehicles such as tank trucks, fuel trucks, sprinkler trucks, sewage trucks, feces trucks, fire trucks, high-pressure cleaning trucks, road obstacle cleaning trucks, aerial work trucks, garbage trucks, etc. The drive shaft is the shaft that can transmit
Troubleshooting Drive Shaft Damage Symptoms and Troubleshooting
Eliminate the symptoms and faults of drive shaft damage 1. If the speed of the car changes suddenly while driving, the drive shaft makes a metal knocking sound, indicating that individual flanges or universal joint cross bearings are worn too much and loose, causing abnormal noise in the drive shaft. 2. When the car starts, the drive shaft makes a "bang" sound or the noise is very chaotic. When the car is reversing on a gentle slope, it makes a sound. The intermittent "click" sound indicates that the needle roller is broken or broken, and the needle roller bear
What are the hazards of transmission shaft torsional vibration?
There are many hazards of drive shaft vibration, which will produce noise, reduce transmission efficiency, loosen fit, and even cause parts to break and cause accidents. Due to the high speed of the drive shaft, its rotation time changes. When it is unbalanced, it will generate large centrifugal forces of different sizes and directions. The light ones will produce vibrations, and the heavy ones will produce bending and twisting deformations, aggravating the wear of the drive shaft splines, intermediate bearings, universal joint cross journals, etc. In severe cases, the car body
The main purpose of making the transmission shaft hollow
The reason is that the drive shaft needs to withstand torque stress and hollow settings during operation, which will increase the transmission performance and have no effect on the use of the drive shaft. The drive shaft is an important device for vehicle power transmission and exists in the vehicle chassis. If it is damaged, the vehicle cannot drive. Since the drive shaft is a rotating body with high speed and less support, its dynamic balance is very important. The drive shaft can transmit power from the engine to the front and rear axles. For front-engine r
Backward standards in the gear industry restrict development
The development process of China from a major gear manufacturing country to a powerful gear manufacturing country is the process of rapid improvement of gear product standards. It is an inevitable trend for enterprises to become the main body of standard setting. "To promote the standardization work of my country's gear industry, we must break the thinking model under the planned economy and follow the path of standardization development in the market economy." Wang Shengtang, secretary-general of the Gear Professional Association, recently called in
Quenching treatment takes the spiral bevel gear to a higher level
The manufacturing process of a good spiral bevel gear is very complex, and generally speaking, after its formation, we still need to undergo quenching treatment. The surface quenching of spiral bevel gears can obtain martensite with high hardness by changing the surface structure of the parts, while also retaining the core toughness and plasticity. It's passing through the table
Non Martensitic Structure of Spiral Bevel Gears
When we use spiral bevel gears, we may hear the term 'non martensitic structure'. What is it? In fact, the non martensitic structure of spiral bevel gears is another name for the black structure on the surface of carburized or carbon nitrogen co carburized gears. Generally speaking, after quenching the spiral bevel gears, fine needle like high carbon martensite may sometimes appear on the surface of the parts. However, due to various reasons, mixed structures such as bainite and troostite may form on the surface of the gears, so we are accustomed to calling
The spiral bevel gear steering needs to be judged in this way
Almost all mechanical equipment uses spiral bevel gears, but we also need to have a certain understanding of their steering when using them.
It's really not good not to pay attention to matters such as spiral bevel gears
Although spiral bevel gears are used well in many mechanical equipment, we still need to pay attention to some issues when installing them, otherwise it may cause serious consequences for our use.1. When installing the spiral bevel gear, adjust the centerline of the two shafts to the same plane, and then we can proceed with the next installation.2. Secondly, it is necessary to conduct a coloring inspection on the contact surface. We should pay attention not to
Types and characteristics of spiral bevel gears
In our various mechanical equipment, it can be said that spiral bevel gears have good use, but when we use them, we also need to distinguish the characteristics of different types, so that we can achieve better results when using them.
Attention should be paid to the installation of spiral bevel gears
Spiral bevel gears have always been used well in our daily lives, and it can be said that most mechanical equipment is used. If we want to maintain its performance and reduce the failure rate, then we need to pay more attention during installation.
Juli teaches you how to choose spiral bevel gears
For us, spiral bevel gears are actually a very important mechanical component, as they are used in most mechanical equipment. If the quality of spiral bevel gears is not good, it will have a significant impact on our use. Below, Juli will tell you some shopping tips.
What is the purpose of quenching the bevel gear of the gearbox
The purpose of quenching the bevel gear of the reducer is to undergo martensite or bainite transformation, obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to significantly improve the steel The strength, hardness, wear resistance, fatigue strength, and toughness can meet the different usage requirements o
Although spiral bevel gears are widely used in our daily lives, many people know and do not know the reason behind them. In fact, the tooth shape of spiral bevel gears is circular arc shape, and most of them are conical, just like the shape of umbrellas, which is why they have this name. The performance of spiral bevel gears is very good, with smooth transmission ratio and low noise transmission performance. Its use can effectively improve the performance of our machinery and reduce the wear of various components. Therefore, we are widely using it, and in differen
Which comes first in terms of bevel gear design shape or mechanism?
The issue of who comes first and who comes last in the design of bevel gears has always been a contradictory topic. Generally speaking, the purpose of styling design is to meet the needs of mechanism design, or to start styling design after the completion of mechanism design. Moreover, due to different product characteristics, we cannot generalize. Moreover, in the process of modeling, its characteristics can be equivalent to a reproduction of the mechanism design process, which means that the purpose of modeling is not only the shape elements, but also the
