Which of the following transmission gear ratios reduces transmission output shaft speed the most?

Which of the following transmission gear ratios reduces transmission output shaft speed the most?

The reduction ratio is the basic parameter of each reducer, because each reducer must have a speed ratio. The meaning of the reduction ratio is very simple, that is, how many times the motor is output after decelerating through the reducer. The calculation formula is the rated output speed of the motor ÷ the final input speed = speed ratio. For example: a motor rated at 3000 rpm, the final output speed after deceleration is 30 rev / min, the reduction ratio = 30 ÷ 3000 = 1 / 100, this time you need a reduction ratio of 1 /100 reducer.

Which of the following transmission gear ratios reduces transmission output shaft speed the most?

Which of the following transmission gear ratios reduces transmission output shaft speed the most? So what is the reduction ratio? First of all, we need to understand the structural principle inside the reducer. Whether it is a gear reducer or a worm gear reducer, the speed is changed by the meshing of the large and small teeth. Therefore, the reduction ratio is also related to the number of gears. The speed ratio is small, for example, 1/3, 1/5, which can be achieved with a small number of gears, but if the speed ratio is 1/1000, the number of gears needed is much, so the speed reducer is generally There are also grades, the most obvious being the miniature reducer and the planetary reducer. The 1st gearbox is a reduction ratio of 1/10 or less, and the 2nd gearbox is a reduction ratio of 1/10 to 1/50. The 3-stage gearbox is a 1/50-up reduction ratio. Which of the following transmission gear ratios reduces transmission output shaft speed the most?The higher the number of gearboxes, the more gears are used. The volume and length of the gearbox will increase accordingly, and the cost will naturally vary.

In addition to the calculation of the output speed, the reduction ratio can roughly calculate the final output torque. Which of the following transmission gear ratios reduces transmission output shaft speed the most?The reducer has a very important function. In addition to reducing the output speed, it also increases the output torque. This is a decisive factor for many heavy-duty instruments. Which of the following transmission gear ratios reduces transmission output shaft speed the most?Then how to calculate how much torque the reducer increases is actually very simple, using the torque input by the motor × speed ratio × transmission efficiency = final output torque. For example: the torque input to the motor is 2N.M, the speed ratio is 10, and the transmission efficiency is 80%, then the final output torque is 2 × 10 × 80% = 16N.M. Of course, this algorithm is only a rough estimate. The final accurate output torque needs to refer to the accurate data given by the major manufacturers. These data are obtained through accurate measurement in the laboratory. Another is that the final output torque is also limited by the allowable torque of the reducer itself. For example, the allowable torque of the reducer is 50N.M, and the final output torque is matched to 100N.M when the reducer is equipped.Which of the following transmission gear ratios reduces transmission output shaft speed the most? It is far beyond the allowable torque of the reducer, and it is easy to damage the reducer while not outputting so much torque. Therefore, when selecting or calculating the speed ratio, it is not a single consideration of the output speed, and there are a series of problems that need to be determined before the gear reduction ratio of the gear reducer can be selected.

Which of the following transmission gear ratios reduces transmission output shaft speed the most?

The input speed control range of the worm gear reducer refers to the speed at which the motor is delivered to the input end of the worm gear reducer. This speed will affect the service life of the worm gear reducer. The normal value is less than 2500 rpm. Only when the input speed is controlled, the output speed can be obtained. The normal input speed is controlled at 1400 rpm, which is the 4 or 6 we usually use. Stage motor. The problem with excessive speed is not only noise and heat, it puts pressure on the surface of the worm and the bearings. Greatly shorten the service life.Which of the following transmission gear ratios reduces transmission output shaft speed the most?
   Whether it is NMRV worm gear reducer or WP series worm gear reducer, the service life of small speed ratio high speed worm gear reducer is relatively shorter than that of slow speed. When the worm gear is assembled, there is a positive assembly, a negative position, and a zero assembly has a certain influence on the noise and load of the reducer, as well as wear.Which of the following transmission gear ratios reduces transmission output shaft speed the most? When you talk about the manual rotation, the low speed reducer has a small head on one side of the worm wheel. The motor speed is fast and has a certain vibration effect. There are tiny single-faced hairs at the root of the tooth that have intermittent abnormal sounds. Solution: Load the boot for a few hours, the sound will be much smaller. Secondly, the cause of this phenomenon is that the natural vibration frequency of the reducer and the frequency of the motor resonate.

Which of the following transmission gear ratios reduces transmission output shaft speed the most?

The angular velocity of the gear rotation is only related to the angular velocity of the drive shaft you are giving. On the same rotor, the angular velocity is equal everywhere; but the linear velocity is related to the radius of the gear. If the angular velocity is set to w, the linear velocity is set to v, and the gear radius is Set to r to have the following relationship v=rw

If the number of teeth of the gear 1 is: Z1, the rotational speed is: n1, the number of teeth of the gear 2 is: Z2, and the rotational speed is: n2, the relationship between the rotational speed of the two meshing gears and the number of teeth is: n1/n2=Z2/Z1

Gear ratio and speed
Rigid body fixed axis rotation: When the rigid body moves, a straight line in the body is always fixed, and each point is circularly moved around the line. Angular velocity: indicates how fast the rigid body rotates. Symbol: ω, unit: rad / s (radians / sec)Which of the following transmission gear ratios reduces transmission output shaft speed the most?
Speed: Use the number of revolutions per minute to indicate the speed of rotation. Symbol: n, unit: r/min
Conversion relationship between angular velocity and rotational speed: ω=2πn/60(rad/s)=30πn/30(rad/s)

Which of the following transmission gear ratios reduces transmission output shaft speed the most?

Line speed: The speed at which a particle of circular motion moves along its tangential direction, also known as the peripheral speed. Symbol: v, unit: m/s.Which of the following transmission gear ratios reduces transmission output shaft speed the most?
The relationship between line speed and angular velocity: v = rω
Then the relationship between line speed and speed: v = rω = πnd(m/s)
The distribution of the velocity of each point on the rotating rigid body: a linear distribution.

Comparison of speed:
1. I1=23/31=0.7419 2. I2=22/30=0.7333 The speed ratio is not much different and does not affect the use. Center distance comparison:
D1=m(23 31)/2=27m D2=m(22 30)/2=26m Gap =21m-26m=1m where: m is the modulus of the gear.
From the above calculation, if the distance between the two shafts of the mounting gear is constant,
The gap between the two newly installed gears will become larger, although it can be used, but it is not ideal. High noise, fast wear and short life.
