How to calculate the oblique downward conveying force of chain

1. First determine the required tension and service life, and then according to the two main parameters and structure determine the chain, sprocket model, different pitch and row number, the tension is different

2.

If the chain wheel with 10 teeth is used as the initial wheel to receive the power of the transmission chain

every minute 1400 / [25000mm / 10 * 38.1 = 65.6 {66}] = 21.336

it is necessary to add a recer of 1: {21.336} about 20 between the motor and the first sprocket. The 10 tooth sprocket is installed on the output shaft of the recer. The input shaft of the recer is connected with the motor at a ratio of 1:1

the transmission chain travels 25000mm / min

3. You tell people that sprocket diameter is useless, tell sprocket pitch, and number of teeth, they can help you calculate the data below. You can check the chain specification manual first, and then you may
calculate by yourself
If a 10 tooth sprocket is used as the initial wheel to receive the power of the transmission chain
1400 / [25000mm / 10 * 38.1 = 65.6 {66}] = 21.336 per minute
it is necessary to add a recer of 1: {21.336} about 20 between the motor and the first sprocket. The 10 tooth sprocket is installed on the output shaft of the recer. The input shaft of the recer is connected with the motor at a ratio of 1:1
the transmission chain travels 25000mm / min
don't your conditions tell you the speed of 25m / min?

4. The difference between gear transmission and chain transmission:
1) gear transmission is the most widely used transmission form in mechanical transmission. Its transmission is more accurate, high efficiency, compact structure, reliable work, long life
the advantages of gear transmission are: constant instantaneous transmission ratio and high stability, stable and reliable structure, low noise, high transmission power and high efficiency. The transmission speed range is large, the transmission ratio is large, the structure is compact and the service life is long
the disadvantages of gear transmission are: high application environment requirements, good lubrication conditions, not suitable for the transmission between two shafts with more st and long distance, high manufacturing and installation accuracy
2) chain transmission is a kind of transmission mode which transfers the motion and power of the driving sprocket with special tooth shape to the driven sprocket with special tooth shape through the chain. The average transmission ratio of chain drive is accurate, the work is reliable and the efficiency is high; The transmission power is large and the overload capacity is strong
the advantages of chain drive are: the requirements for application environment are generally not very high. It can be used in high temperature, heavy load, low speed and sty environment, and it is suitable for transmission between two distant shafts. It can ensure accurate transmission ratio, high transmission power, small force acting on the shaft and high transmission efficiency
the disadvantage of chain drive is that the hinge of the chain is worn, which makes the pitch larger and causes the chain to be disjointed. Installation and maintenance requirements are high.

6. Friction, simplify the chain into a rope, mainly depends on whether it is broken in the case of tension

7. The tension of chain drive is related to the allowable sag, please refer to the manual. In general, it can be ignored.

8. Speed calculation formula: v = n / I * pi * D * Z electric / Z axis
from what you know: I = 1400 / 7.5 * 3.14 * 0.08137 (chain conveyor drive should be determined by the diameter of driving wheel, I don't know what your roller diameter is.) It is calculated that I = 47.69, i.e. the recer with rection ratio of 47.69 should be selected. If you want to round the rection ratio, you can adjust the sprocket of general motor and shaft. Shanghai Dayton sincerely serves you.

9. The tensioning wheel is generally arranged at the loose side of the chain, and its position is determined according to the needs
so you can choose both 3 and 4

V-belt drive
1. Install the tension pulley on the inner side of the loose side of the belt near the big pulley. It is often used when the center distance is not adjustable
2. Use the suspended load to make the tension wheel automatically press on the outside of the belt loose edge and close to the small wheel. It is used in the occasion of large transmission ratio and small center distance
chain drive;

10. Because the working condition is unstable, it is generally not calculated
analogy is recommended. Visit more similar mature equipment.
