Converting power transmission (Theory)
Gearbox no load
Torque (Motor >> Drive) | 1.95 | 1.792 | 1.633 | 1.528 | 1.475 | 1.38 | 1.317 |
Gearbox | 1:1 | 6:5 | 3:2 | 9:5 | 2:1 | 5:2 | 3:1 |
Torque (Motor << Drive) | 1.95 | 2.14 | 2.425 | 2.71 | 2.9 | 3.375 | 3.85 |
The torque sensor adds 1 to the measurements, without adding real resistance. Let’s check the results of the force conversion.
Let’s calculate the ratio 1:1, subtract 1 unit added by the torque sensor. 1.95-1=0.95 We got a gearbox efficiency of 95%
Let’s calculate the ratio 3:1, subtract 1 unit added by the torque sensor. And divide by the gearbox ratio. 3.85-1=2.85 2.85/3=0.95 We got a gearbox efficiency of 95%
Let’s calculate the ratio 1:3, subtract 1 unit added by the torque sensor. And multiply by the gearbox ratio. 1.317-1=0.317 0.317*3=0.951 We got a gearbox efficiency of 95%
The no-load gearbox converts power as expected.
Gearbox load 1 torque
Torque (Motor >> Drive) | 2.9 | 1.63 |
Gearbox | 1:1 | 3:1 |
Torque (Motor << Drive) | 2.9 | 6.7 |
Let’s calculate the ratio 1:1, subtract 1 unit added by the torque sensor. Subtract torque 1 of the small generator 2.9-1=1.9 1.9-1=0.9 We got a gearbox efficiency of 90%
Let’s calculate the ratio 3:1, subtract 1 unit added by the torque sensor. Divide by gearbox ratio. Subtract torque 1 of the small generator 6.7-1=5.7 5.7/3=1.9 1.9-1=0.9 We got a gearbox efficiency of 90%
Let’s calculate the ratio 1:3, subtract 1 unit added by the torque sensor. Multiply by the gearbox ratio. Subtract torque 1 of the small generator 1.633-1=0.633 0.633*3=1.899 1.9-1=0.9 We got a gearbox efficiency of 90%
All right
Converting power transmission (Small Electric Motor)
Small Electric Motor > Torque Meter > Gearbox > Torque Meter > Medium Generator
Rps | Torque | Ratio | Rps | Torque | Generate |
8.53 | 33 | Direct | 8.53 | 33 | 17.53 |
8.36 | 32.45 | 1:1 | 8.35 | 33.85 | 16.80 |
6.97 | 38.34 | 6:5 | 8.36 | 33.37 | 16.84 |
5.58 | 47.17 | 3:2 | 8.37 | 32.9 | 16.88 |
4.66 | 56 | 9:5 | 8.37 | 32.58 | 16.9 |
4.19 | 61.9 | 2:1 | 8.37 | 32.42 | 16.91 |
3.36 | 76.62 | 5:2 | 8.38 | 32.14 | 16.93 |
2.8 | 91.35 | 3:1 | 8.38 | 31.95 | 16.95 |
The final speed of the generator is approximately the same at different gearbox ratios. 3:1 efficiency even slightly higher than 1:1. Let’s count.
RPS of the motor at a ratio of 1:1 8.36 divided by a gearbox ratio of 3:1 8.36/3=2.78
A little less than it turned out during testing
Torque at a ratio of 1:1 32.45, subtract 1 unit added by the torque sensor. And multiplied by a gearbox ratio of 3:1 32.45-1=31.45 31.45*3=94.35
Resistance is greater than it turned out during testing
And although the efficiency of the gearbox turned out to be more than 100%, the difference is subtle, but it is a bug and needs to be corrected.
Converting power transmission (Small Engine)
Small Engine > Torque Meter > Gearbox > Torque Meter > Medium Generator
Rps | Torque | Ratio | Rps | Torque | Generate |
17.66 | 41 | Direct | 17.66 | 41 | 75.18 |
17.33 | 40.45 | 1:1 | 17.29 | 41.45 | 72.01 |
12.29 | 46.34 | 6:5 | 14.71 | 39.7 | 52.19 |
8.16 | 55.17 | 3:2 | 12.22 | 37.97 | 35.97 |
5.9 | 64 | 9:5 | 10.61 | 36.8 | 27.16 |
4.93 | 69.9 | 2:1 | 9.84 | 36.22 | 23.34 |
3.4 | 84.62 | 5:2 | 8.5 | 35.18 | 17.4 |
2.55 | 99.35 | 3:1 | 7.65 | 34.48 | 14.09 |
The final speed of the generator is very different for different gear ratios of the gearbox. Efficiency 3: 1 is several times lower than 1: 1. Let’s count.
RPS of the motor at a ratio of 1:1 17.33 divided by a gearbox ratio of 3:1 17.33/3=5.78
The final speed should be more than double.
Torque at a ratio of 1:1 40.45, subtract 1 unit added by the torque sensor. And multiplied by a gearbox ratio of 3:1 40.45-1=39.45 39.45*3=118.35
The load should be more than the testing showed.
The results turned out to be strange, something is definitely missing here. Perhaps the torque that I still can’t catch somehow affects.
In search of torque diesel engines
Small Engine > Torque Meter > Medium Generator x3
Small Engine > Torque Meter > Gearbox > Torque Meter > Medium Generator
Small Engine x3 > Torque Meter > Gearbox > Torque Meter > Medium Generator
Medium Engine > Torque Meter > Gearbox > Torque Meter > Medium Generator
Rps | Torque | Ratio | Rps | Torque | Generate |
6.49 | 101 | Direct | 6.49 | 101 | 30.43 |
2.55 | 99.35 | 3:1 | 7.65 | 34.48 | 14.09 |
6.37 | 119.35 | 3:1 | 19.07 | 40.82 | 87.66 |
6.37 | 119.35 | 3:1 | 19.07 | 40.82 | 87.66 |
no conclusions
