电动葫芦在现代工业中应用非常广泛。目前国内大量生产的电动葫芦,一般是由电动机通过三对渐开线齿轮,将扭矩传递给低速轴的。这种齿轮传动具有加工维护方便、效率高等优点。但一般低速软齿面齿轮也相应存在一些问题,例如一级传动速比范围受到一定的限制,使用寿命短,不能承受超载或冲击载荷等等。而摆线针轮传动可以弥补这些缺陷,应用在电动葫芦起升装置上具有如下优点: (1)用摆线针轮代替原渐开线齿轮,可减少轴承的数目,并使电动萌芦的长度从1100mm左右缩短到
Electric hoist in the modern industry is widely used. At present, mass production of electric hoist, usually by the motor through the three pairs of involute gear, the torque is passed to the low-speed shaft. This gear transmission has the advantages of convenient processing and maintenance, high efficiency. However, the general low-speed soft-tooth gear there are some problems, such as a transmission ratio range subject to certain restrictions, short life, can not withstand overload or impact load and so on. The cycloid drive can make up for these shortcomings, used in electric hoist lifting device has the following advantages: (1) with cycloid pin instead of the original involute gear, can reduce the number of bearings, Shorten the length from about 1100mm to
