CD型10吨电动葫芦是我国生产的CD型一般用途钢丝绳式电动葫芦中规格最大的一种。它的卷扬用电动机采用锥形转子制动电动机,不仅能起卷扬的作用,而且还起着制动器的作用。在我厂试制和生产过程中,制动问题一直是影响产品质量的关键问题之一。原设计的锥形转子制动电动机制动力矩不够,下滑量太大;制动环常开裂,容易损坏,部分零件的强度也不够。针对这些问题,我们进行了一些试验和改进,基本上满足了使用要求。
CD-type 10 tons of electric hoist is China’s production of CD-type general purpose wire rope electric hoist in a specification of the largest. Its hoisting motor with tapered rotor brake motor, not only can play the role of winch, but also plays the role of brake. In our factory trial production and production process, the braking problem has been one of the key issues affecting product quality. The original design of the tapered rotor brake motor braking torque is not enough, the sliding amount is too large; brake ring often cracked, easily damaged, some parts of the strength is not enough. In response to these issues, we conducted some tests and improvements, basically meet the requirements.
