Some questions puzzled me, I hope to study advanced experts, experts can dispel doubts for me. What is the relationship between motor power and driving force? I know that if the power is not enough, the machine can not be driven, such as 110KW, 2P motor through a belt pulley reducer (1:3) drive a hollow cylinder 8000K g, motor power is how to choose? Small, unable to operate the hollow cylinder, the beginning of the operation, the column to overcome what force? 1 minutes to 900 revolutions per minute. When is the maximum torque? Calculate the motor power to check the thickness of the cylinder, how to check? I know the formula for the Q235 steel cylinder, [=T/Wt] (tau section coefficient, but is not torsion). Do I need a converter? T is the maximum torque. What is the maximum torque? How to calculate?
Two. Calculation method of reduction ratio1 calculation methods, definition: speed = input / output speed speed.2 calculation methods, general reduction rate = 9550 / / use the torque motor power input speed, motor power factor.3 calculation methods, gear reduction rate = number of teeth, gear driven gear tooth number (if it is a multistage gear, then all the meshing of a gear group driven gear / gear tooth number, then the result will be multiply.4, belt, chain and friction wheel gear ratio calculation method: reduction ratio = driven wheel driving wheel diameter diameter.
The concept of motor torque:Motor torque, that is, motor output torque, is one of the basic parameters of the motor. The unit is N.M (cattle m).Four 、 the relationship between motor output torque and motor speed and power.1, formula: T=9550P/n this formula is commonly used in Engineering: torque, power, speed of the relationship between the three formulas.Type: T-- torque; 9550-- constant (without having to investigate its origin); P-- motor power (KW); n-- output speed (Rev / min)Note: if you want to calculate torque through the reducer, we should consider the factors of gear transmission efficiency loss.
Motor reduction ratio and torqueI. The concept of speed reduction ratio: that is to say, the transmission ratio of the reduction gear is a kind of transmission ratio, which refers to the instantaneous input speed and transmission in the reduction mechanismThe ratio of speed is expressed by the symbol "I". If the input speed is 1500r/min and the output speed is 25r/min, then the reduction ratio is i=60:1.
