What is the current price of digital currency MVP
as time goes by, half of a year has passed. Now let's review the market trend of bitcoin in 2019. After last year's bear market, the trend of bitcoin has been at a low ebb, with the lowest falling to 3155. After that, on the first day of the new year, it will enter a state of shock and energy accumulation, It wasn't until about 8 a.m. on April 1 that the market ushered in the dawn. During the rise at 4000, the market experienced a period from 9000 high in May to 13970 high in June. During this period, many friends who were trapped in high positions last year were out of the game or entered low positions to gain profits. After the market in June, the overall trend of bitcoin entered a callback state, After digesting the sequelae (large volume) brought by the rising trend ring this period, the fluctuation range is between 9000-10000. The wave was used for nearly two months, and it started a new round of pull-up at the end of July 21. After reaching 12500, it is now in a state of callback. How do you view the overall direction of the later disk
although the market in the past two days is in a state of correction and repair, the overall market trend of bulls is not finished, but hidden. From the weekly market, we can see that the bull's rising space has not yet come out completely, but is waiting for a new round of rising at the bottom of the market, and the weekly bullion belt index is all up, In this week's market, we can see that the rally and the callback account for half of each other, and the long rally is pushed by the energy and there is a sharp decline. This is a signal. The key to the sustainability of the long market is the update of the market index next week. If the momentum of the long market does not enter the market, the market will change, Please take a rational view of the trend
at present, the daily short position is graally strong in the evening, and the daily indexes of Ma5 and ma10 above the market show signs of dead cross downward. As long as the daily line of ma10 is shifted downward, there will be a short-term decline. Although 11400-11200 below is the short-term support of the daily line, as long as the short position of Ma5 and ma10 above the market touches the hundreds of points below, it is impossible to hold, At that time, 11000 is the watershed, so we need to pay attention to the short-term pressure range of 11800-11700. The 4-hour market is in the stage of rebound from the recent decline reaching the bottom of 11400. At present, the pressure above the short-term market is 11700. If the rebound kinetic energy does not reach the top and the lower Ma5 moving average continues to decline, then the short market will continue. This is the point that should be paid attention to by friends who are staring at the market at night
the operation idea is that if the market rebounds to the upper 11700-11800 pressure range, then the target range of 11500-11400 can be seen under the entry empty order, and 11000-11200 can be regarded as the bottom in the short term if it can continue to be short, and the bull short-term change needs to pay attention to the upper 11700 pressure position, and if the market rise breaks and stands firm, then the entry empty order can test the upper 11800-11900, The overall idea is to take short positions as the main method and take long positions as the auxiliary method.
if you have a friend who has an operation, take stop loss and stop profit, and do a good job in risk control. If you don't understand the market analysis or understand it in the early stage, please enter the market cautiously. I hope you can plan the worst result for every operation. After all, it's all real gold and silver, and your own hard money, It's best to be able to afford the return of your own efforts. Of course, some friends need to keep in touch with shanghua operation, and they will pass it one by one later
the ranking of digital currency can be measured according to multiple dimensions, such as market value, technical ability, landing in Cheng, 24-hour rise and fall, 24-hour turnover list, 24-hour turnover rate, etc. For the sake of data accuracy, we list the ranking of virtual currencies in the market value list<

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 angleB. 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
