Motor shaft with insulating ceramic and preparation method thereof
The invention discloses a motor shaft with an insulating ceramic, which comprises a shaft body, an annular groove is formed in the outer ring of the shaft body, and an annular insulating ceramic layerwith the thickness of 0.012-0.015 mm is covered in the groove. The invention discloses a preparation method of the motor shaft with the insulating ceramic, which comprises the following steps: ball-milling and mixing alumina powder, composite basalt fiber, zirconium dioxide, cerium dioxide, polyvinyl butyral, a flexibilizer, a densifier, a refiner and a tackifier until the particle size is less than or equal to 0.1 mu m, and drying at 105-112 DEG C to obtain a premix; derusting and descaling the surface of a shaft body through a grinding wheel to be smooth and clean, then polishing the shaftbody through abrasive paper, removing greasy dirt with acetone, pickling with hydrochloric acid, washing with ethanol, and drying to obtain a pretreated shaft body; and electroplating the premix to the surface of the pretreated shaft body, accurately grinding until the coating thickness is 0.012-0.015 mm, and polishing to obtain the motor shaft with the insulating ceramic.
本发明公开了一种带绝缘陶瓷的电机轴，包括轴本体，轴本体外圈开设有环形凹槽，凹槽内覆有厚度为0.012‑0.015mm的环形绝缘陶瓷层。本发明公开了上述带绝缘陶瓷的电机轴的制备方法，包括如下步骤：将氧化铝粉末、复合玄武岩纤维、二氧化锆、二氧化铈、聚乙烯醇缩丁醛、增韧剂、致密化剂、细化剂、增粘剂球磨混料至粒径小于等于0.1μm，105‑112℃干燥得到预混料；采用砂轮对轴本体的表面进行除锈，去氧化皮使其表面光洁，然后用砂纸进行打磨，然后依次用丙酮去除油污，盐酸酸洗，乙醇冲洗，干燥得到预处理轴本体；将预混料电镀至预处理轴本体表面，精磨后涂层厚度为0.012‑0.015mm，抛光得到带绝缘陶瓷的电机轴。
