How much do you know about digital currency

1. Daily share short-term currency strategy, how to invest * digital currency with high return, less than a year and a half from the countdown to bitcoin halving, the last wave of 10 ~ 100 times

2. If you don't use the company's quotation, it may be different. I suggest you ask the customer service staff of chainup to get the accurate quotation information.

3. You have said that digital currency and RMB are 1:1 equal use, then 10 million digital currency, of course, can be converted into 10 million RMB

4. That's not the difference between Alipay's money and your simple understanding. In this way, you can inspect DCPRO specifically.

5. It should be one yuan fund
in July 2015, one yuan fund obtained the registration certificate of private equity fund manager issued by China Securities Investment Fund Instry Association, registration number: p1017159. It is a legal and compliant management company engaged in private equity investment
if one yuan fund refers to digital currency, it should be cautious. It may only be under the guise of digital currency. The real digital currency is cryptocurrency with a good application scenario planning, such as bitcoin, Ruitai coin, Laite coin, Qianjin card, etc.

To calculate the helical gear parameters, you need to know the basic parameters:

normal molus M_ n. Number of teeth Z, normal pressure angle α_ n. Helix angle β

generally, the crown height coefficient h * is 1, and the root height coefficient C * is 0.25. If there is displacement, it is necessary to calculate the displacement: x

the following is the basic parameter

end face molus: M_ t=m_ n/cos β

Calculation formula of pressure angle at the end face: Tan α_ t)=tan ( α_ t)/cos( β)

diameter of dividing circle: D = m_ n × z/cos( β)

addenm circle diameter: no displacement: Da = D + 2 × m_ n × H * with displacement: Da = D + 2 × m_ n × H * + x)

root circle diameter: no displacement: DF = D-2 × m_ n ×( H * + C *) with displacement: DF = D-2 × m_ n ×( H * + C * - x)

diameter of base circle: DB = D × cos α_ t)

in addition, there are more important dimensions, such as normal pitch, end pitch, etc., which can be obtained by referring to relevant manuals

Extended data:

judgment of helix rotation direction: first, we make the gear axis vertical, if the right height of helix is right rotation; On the contrary, the height on the left side of the helix is left-handed

end face and normal surface parameters:

end face: the plane perpendicular to the gear axis, and the parameters on the end face are generally added with subscript t

normal plane: the plane perpendicular to the helix, and the parameters on the normal plane are generally subscript n

(1) pitch and molus: = t= π

(2) pressure angle: generally, the parameters in normal plane are standard parameters

The correct meshing condition: the helix angle must be equal in size and opposite in direction. The normal molus m is equal to the normal pressure angle

B. geometric dimension calculation: in calculation, the calculation formula of spur gear can be directly applied to the end face of helical gear because a pair of helical gear transmission is equivalent to a pair of spur gear transmission on the end plane

there are many kinds of gear transmission, among which the efficiency of helical gear is very high, for example, the efficiency of spur gear transmission is lower than that of helical gear transmission

Like spur gear mechanism, helical gear can be used to improve the load capacity of transmission by recing the center distance a, which can be used for high-speed operation. Helical gear recer is a new type of recer. The helical gear recer is small in volume, light in weight and good in economy

Advantages:

(1) good meshing performance: the meshing process between helical cylindrical gears is an excessive process, and the force on the teeth is graally from small to large, and then from large to small; Helical gear is suitable for high speed and heavy load

(2) large coincidence degree: the increase of coincidence degree can improve the bearing capacity of gear. So the life of the gear is prolonged. The coincidence degree mainly depends on the meshing time, while the long meshing time and large contact area of helical gear rece the stress. The transmission is stable and the economy is increased

(3) compact structure: the less the minimum number of teeth, the more compact the structure

7. The mainstream of legal digital currency trading platform is dcpro. Many people know about it and have formal supervision.

8. Digital currency and RMB have the same value. One yuan of digital currency is equal to one yuan of RMB. Their area is equal.

9. Hello, now CCT digital currency can be sold for nine yuan. You're talking about chains! Believe it

10. The central digital currency is now more than 50 yuan per share
