A method of reducing rotational torque when drilling with casing by introduction of friction reducing bearing rings 5,6,7 into the wall of casing couplings 1. The reducing bearing rings may be located in recessed grooves 4 formed into the wall of the casing couplings or upset sections of the...
4000 Nm torque 27:1 reduction ratio 2 stage planetary gear reducer DQ4B27E Product description: Daixin planetary reducer gearbox is designed with large torque, high start and transmission efficiency, low-speed stability, compact radial size, low noise, etc. Th...
To do work a power device needs to supply a given supply of torque, and until this measure of torque is supplied the desired performance will not be met. In a gasoline engine the desired torque/horsepower is compensated with higher factors due to the inefficiencies of that system to reach ...
Table 1. Average torque reduction given by the mechanism’s reconfigurability. It can be seen that there is no discontinuity on the evolution of the collected spinning angle displayed in Figure 13. This shows that a robotic manipulator based on a 3-RRR SPM can be smoothly controlled to gen...
the magnet skewing approach and the selecting an appropriate magnet pole arc to pole pitch ratio, according to the cogging torque reduction and the negative impacts on the generator loadability. It is shown that using the proposed approach, the generator cogging torque can be greatly reduced (...
