Description

Worm gear low-loss lifting transmission device of clothes airing machine Technical Field The invention relates to the technical field of transmission structures of airing machines, in particular to a low-loss lifting transmission device of a worm gear type airing machine. Background In the airing machine field, lifting transmission device is the core component that realizes clothing lifting function, its transmission efficiency and stability directly influence the use experience of equipment, worm gear transmission structure is because of possessing meshing steadily, the transmission ratio is accurate and auto-lock characteristic, by wide application in airing machine lifting system, the adaptation is light-load, low-speed working scene, current airing machine's worm gear lifting transmission device is usually by the worm wheel, worm, transmission shaft and gear box are constituteed, worm and driving motor output shaft, through worm wheel worm's meshing transmission with power transmission to elevating system, realize the steady lift of clothes hanger, for reducing the friction loss in the transmission process, such device is mostly at the meshing region of worm wheel and worm scribble lubricating grease, partial structure can install bearing or axle sleeve additional in the cooperation department of transmission shaft and gear box, in order to reduce the friction that relative motion produced.
