The cylindrical gearbox (RC, TsU, RCD) is a unique design, the operating principle of which is based on spur gears. Basically, this mechanism is used in drives of various machines and mechanisms for changing torques, as well as in mechanisms where there is a need to transfer rotational movements between shafts and the need to reduce the speed of rotation of the shaft. Modern helical gearboxes are both horizontal and vertical and they are classified according to the following technical characteristics:
- number of gears (one-stage, two-stage, three-stage, four-stage);
- clearance between the axes of the input and output shafts;
- installation method (feet, flange, push-on design).
Positive aspects of using the gearbox control gear in drives
Such popularity of the cylindrical gearbox is due to the following factors:
- one of the main advantages of the CU gearbox is a high level of efficiency, which makes it energetically economical. The efficiency reaches 98%, and the transmitted power is not lost, due to which the components of the mechanism practically do not heat up;
- high load capacity (very little power loss during operation);
- due to the small clearance of the output shaft, the level of kinematic accuracy is much higher than that of worm cylinders;
- complete lack of self-braking;
- stable and trouble-free operation under uneven loads and with frequent starts and stops (in drives of crushers, grinders and other machines with pulsating load);
- reliability.
Negative moments of helical gearboxes:
- a small number of gears in one stage;
- the operation of cylindrical gearboxes is accompanied by a lot of noise compared to worm gearboxes;
- lack of self-braking (a disadvantage in those cases when no rotation of the external load shaft is required).
Based on the above, we can make the following conclusion: the consumer purchases gearboxes of this type more often than any other. This is due to the fact that when buying a gearbox (machines with a cylindrical gearbox), you can be sure that it will serve you for a long time and reliably. Also, when choosing a gearbox, it is important not to make a mistake in the calculations, since it is important to take into account the maximum allowable loads on it. If the calculation is incorrect, you can lead your mechanism to rapid wear or even breakdown, which will entail repairs and financial waste and it does not matter if you buy the most popular gearbox c2u 200 or less popular RCD 400. Therefore, entrust the calculations to experienced specialists who will be able to correctly take into account all the nuances
