Drum coupling is a new type of flexible coupling, mainly for the reducer output shaft connected with the wire rope drum lifting equipment lifting mechanism also applies to other similar not only transfer torque to withstand the diameter mechanical equipment to load, but can not be used as required to withstand the axial load transmission. Drum coupling operating temperature -25 ~ +80 ° C; transfer nominal torque of 16 ~ 560 kN? M; the allowable radial load is 18 ~ 355 (KN). Coupling with other reel drum coupling has the following characteristics: 1.3.1 stable and reliable, able to withstand large radial load and transmission of high torque, overload. Compact and solid, series designed to simplify the whole structure, to reduce the weight of equipment. Tune-bit performance, installation, easy adjustment and simple maintenance. With positioning wear indicator, safe and reliable. Can be equipped with the common shaft reducer, reducing equipment costs.
