How to calculate the axial force on the helical gear

1.

is a cross border payment third party payment platform developed by block chain technology. It is similar to Alipay and WeChat. It is developed by the technology of cross link block chain. It is also a digital currency trading platform. It is also a financial investment platform, or a platform with its own consumption. p>

now, people in many countries are using this platform for financial management and consumption, which is a very good platform. This is still in the promotion stage. For example, the earliest promotion stage of Alipay is a good time to make money for investment. It will create countless millionaires just like the Alipay promotion stage. p>

payment platform principle:

in addition to online banking, e-credit card and other means, there is another way to relatively rece the risk of online payment, that is, the rapidly developing payment mode and payment process using the third-party organization, which must have a certain degree of integrity. In the actual operation process, the third party organization can be the bank itself that issues the credit card

in online payment, the disclosure of credit card number and password is only transferred between the cardholder and the bank, which reces the risk caused by the transfer through the merchant. Similarly, when the third party is an organization with good reputation and technical support ability other than the bank, the payment is also made between the cardholder or the customer and the bank through the third party

the cardholder first transmits the account information with a third party in the form of some electronic data (e.g. e-mail) instead of the bank account, so as to avoid the cardholder directly disclosing the bank information to the merchant. In addition, the cardholder does not have to log in to different online banking interfaces. Instead, each time he logs in, he can see the relatively familiar and simple interface of the third party organization

relevant agreements are signed between the third-party institutions and major banks, so that the third-party institutions and banks can carry out some form of data exchange and relevant information confirmation. In this way, the third-party organization can establish a payment process between the cardholder or consumer and each bank, as well as the ultimate payee or merchant

2. When you transfer money to me, I will give you a string of codes. This code is the address where I collect money. The address format corresponding to different currencies will be different, so we must repeatedly confirm whether the address is the currency in the transfer operation. For example, if you use the address of bitcoin to transfer money to the address of Ethereum, it will judge that it is not the address of bitcoin and refuse. However, if you insist on doing so, it may cause the loss of assets. So the address must be verified repeatedly before transfer. You should also pay special attention to whether the first few and the last few are exactly the same as the address given to you by the other party< When it comes to this address, it actually has another function. Blockchain is a completely transparent network. When you give someone an address, it is possible for others to query the transfer, flow and balance of your address. So when we use the address, we should also pay attention to personal privacy. For example, if you give address a to someone, you'd better give address B to another person. This is the most convenient way to protect your privacy.

" grip line" rule : "the left helix uses the left helix, and the right helix uses the right hand. Grasp the axis of the drive wheel, with four fingers representing the direction of rotation except the thumb. The thumb points to the direction of the driving axle toward the force, and the direction of the driven axle toward the force is opposite and equal to that of the driving axle toward the force. ". This rule only applies to driving wheels

Development:

first look at the gear of the left hand or right hand, left-hand rotation with the left hand, right-hand rotation with the right hand, four fingers in the same direction of gear rotation, the thumb upright. If it is a driving wheel, the axial force is the same as that of the thumb. If it is a driven wheel, the axial force is opposite to that of the thumb

4. Helical gear how to use, there is axial force, design and selection of spiral angle small point, deep groove ball bearing can bear. It's better to calculate how much axial force there is and check whether the manual bearing can bear such a large axial force
it's better to use limited position. It's not reliable only by interference fit. It's not good to say when there is a large load and impact

the reverse tension or pressure on a normal section of a structure or component caused by the action of axial force is called axial force when the reverse tension is located at the centroid of the section
it can compete with the gravity of the earth, that is, it can make the object more stable. Gyroscopes and bicycles move on this principle. When he tilts in one direction, this balance will be broken, so a force like this will be generated. The greater the angle of inclination, the greater the force. The flying saucer developed by German Nazis in World War II took off and changed direction based on this basic principle.

"Mechanical design" textbooks are used in the "grip line" rule: "left spiral with left, right spiral with right hand. Holding the axis of the driving wheel, except for the thumb, the other four fingers represent the direction of rotation. The thumb points to the direction of the driving wheel axis to the force, and the direction of the force from the driving wheel axis is opposite to that of the driving wheel axis, and the size is equal to that of the driving wheel axis. This rule only applies to driving wheels

let's see whether it's a left-handed or a right-handed gear, left-handed, right-handed, four fingers circling in the same direction as the gear rotation, with the thumb straight. If it is a driving wheel, the axial force is the same as that of the thumb; if it is a driven wheel, the axial force is opposite to that of the thumb

axial force example

the axial force is inertial force. When an object rotates, it will proce a centripetal acceleration e to the existence of angular velocity. Generally, when an object rotates, it has an instantaneous axis, so it can be regarded as rotating around the instantaneous axis, So the centripetal acceleration points to the instantaneous axis. The direction of inertial force is just opposite to that of centripetal acceleration, which is called axial force

generally, the magnitude of inertial force is related to the angular velocity, mass, shape, and centroid of an object, which can not be solved by a simple formula. When a particle rotates around a fixed axis, the centripetal force F = m * W ^ 2 * r. m is the mass of the particle, W is the angular velocity of rotation, and R is the radius of rotation. If a rigid body rotates on its fixed axis, it will proce inertial force, which belongs to static balance and dynamic balance

8. Memory is hidden by the yellow paper, quietly sealed in the depth of time, waiting for you and me to read
first, put the happiness of value in small things
ten years ago, I clenched my little fist
one weekend, the mother was cleaning dishes in the kitchen, and the lovely child was enjoying himself in the living room. All of a sudden, the mother heard the cry of the child, her hands were not wiped clean, so she rushed out to see the child. The child is still on the sofa, but his little hand is imprisoned by a beautiful flower statue on the tea table. Huazun is narrow at the top and wide at the bottom, like a thin necked wine man with a belly thrust out, so his hand goes in, but he can't take it out.

9. Exhibition instry is a new service instry with wide influence and high relevance. Exhibition economy has graally developed into a new growth point, and exhibition instry is one of the instries with great development potential. In the new era, we must vigorously develop the exhibition instry and comprehensively enhance the exhibition economy
the status and role of the exhibition instry are increasingly prominent, involving instry, agriculture, commerce and many other instries. It plays an important role in structural adjustment, market development, consumption promotion, strengthening cooperation and exchange, expanding proct exports, and promoting the rapid, sustainable and healthy development of the economy The construction of a harmonious society shows its special status and role, and is increasingly emerging. Specifically reflected in:
first, it can proce a strong interaction and win-win effect. The exhibition instry can not only bring direct income such as rental fee and construction fee, but also promote or indirectly drive the development of dozens of instries, directly creating income related to commercial shopping, catering, accommodation, entertainment, transportation, communication, advertising, tourism, printing and real estate; It can not only gather popularity, but also promote the development of major instries, and have a significant impact and catalytic effect on the economic development and social progress of a city or region. According to relevant statistics, a good exhibition can pull the economy to 1:9 or even higher.
