Description

Technical Field

[0001] The present application relates to magnetorheological transmission technology and the field of precision mechanical design technology, and in particular to a magnetorheological turbine reducer. Background Art

[0002] As the manufacturing industry transitions toward intelligent and sophisticated technology, the performance requirements for transmission systems are becoming increasingly stringent. This is particularly true in areas such as industrial robot joints and high-end machine tools. Traditional gear reducers, due to their high noise and low efficiency, are increasingly struggling to meet market demand. In recent years, a new generation of reducers based on magnetic fluid technology has become a research hotspot, finding widespread application due to their high efficiency, long life, and low noise levels. However, most magnetic fluid reducers currently on the market still suffer from complex structures and high costs.

[0003] Some new magnetohydrodynamic reducers attempt to indirectly drive a liquid medium to transmit power through magnetic field regulation. This theoretically reduces contact wear and improves energy efficiency. However, these systems generally face challenges with insufficient integration. In actual production, assembly and debugging are cumbersome, resulting in high failure rates.

[0004] Both traditional gears and emerging magnetic fluid reduction mechanisms have failed to strike a balance between high performance and economy, especially in terms of miniaturization and lightweighting, which limits their wider application scope and development potential. Utility Model Content

In this way, the energy conversion process from high speed to low speed to high torque is completed, which greatly simplifies the physical form of the product, not only facilitates on-site construction deployment but also significantly shortens the subsequent maintenance cycle, greatly saving manpower and material resources.

[0016] By adopting the above technical solution, a sealing installation function can be achieved by arranging a sealing plate.

[0017] Optionally, a slow-start circuit board and a liquid level sensor are respectively provided in the housing.

[0018] By adopting the above technical solution, the current waveform can be smoothed by slowly starting the circuit board to avoid adverse effects caused by instantaneous impact.

[0019] Optionally, the control mechanism includes a control panel and a microprocessor, a power module and related sensors arranged on the control panel.

[0020] By adopting the above technical solution, a control mechanism is set up to creatively introduce intelligent sensing elements to assist in monitoring the working status, realize remote monitoring and early warning functions, and improve the system's self-diagnosis and repair capabilities and user experience satisfaction.
