Description

Technical Field

[0001] This utility model relates to the field of alloy bushing technology, specifically to an alloy bushing assembly for a motor shaft. Background Technology

[0002] With increasing environmental awareness and stricter regulations on pollutant emissions, fields such as sewage pumps and water treatment machinery urgently need environmentally friendly solutions to replace traditional oil lubrication. Water, due to its wide availability, lack of pollution, and low cost, has become an ideal lubrication medium. However, traditional ball bearings are ill-suited for water lubrication conditions: water's viscosity is only 1 / 100-1 / 120 that of oil, making it unable to form a stable hydrodynamic lubrication film. This leads to boundary lubrication or even dry friction during startup, low speeds, or load fluctuations. Furthermore, water (especially seawater and industrial wastewater) can cause electrochemical corrosion of bearing metals, and impurities in the water can exacerbate abrasive wear. Additionally, water's low boiling point can lead to high-temperature vaporization failure, requiring complex sealing structures to prevent water ingress, yet frequent malfunctions still occur, severely shortening equipment lifespan and increasing maintenance costs. Although early water lubrication materials such as ironwood and rubber-based materials were used, they suffered from limitations such as resource scarcity, low load-bearing capacity, and poor temperature resistance. Therefore, the industry urgently needs high-performance transmission components adaptable to water lubrication environments, laying the technological foundation for the subsequent research and application of alloy bushings. Utility Model Content

A screw is rotatably sleeved inside the connecting block via a bearing, and the screw is threadedly connected to the connecting seat. A rotating block is fixedly connected to the outer side of the screw, and the rotating block has an internal hexagonal groove. By designing the anti-rotation mechanism, the fixed sleeve can be limited and prevented from rotating.

One end of the magnetic block is fixedly connected to a plug, which is slidably connected to both the end ring and the motor shaft. A guide rod is slidably fitted inside the magnetic block and fixedly connected to the end ring. A spring is provided on the outer side of the guide rod. A groove is formed inside the magnetic block. The other end of the magnetic block is fixedly connected to a pull rod, which is slidably connected to the end ring. A magnet is fixedly connected to the inner wall of the end ring.
