The noise reduction device for the machine-room-less elevator traction machine comprises a noise reduction box, the noise reduction box comprises an inner box and an outer box, a cavity is reserved between the inner box and the outer box, a plurality of avoiding channels are arranged at the bottom of the inner box and extend to the outer bottom of the outer box from the bottom of the inner box, and the noise reduction box is arranged in the cavity. Wherein one avoiding channel is internally provided with a supporting frame, the supporting frame is used for fixing the traction machine to the top of a lift car, a plurality of elastic pieces are fixedly connected to the supporting frame, the end, away from the supporting frame, of each elastic piece penetrates through the channel wall of the corresponding avoiding channel and is located in the corresponding cavity, and the cavities are filled with clean water. According to the scheme, the supporting frame and the elastic piece serve as media, vibration generated by the traction machine is transmitted into the clear water in the cavity, fluctuation of water is caused through the elastic piece, in this way, the clear water absorbs vibration force of the elastic piece, the vibration force generated by the traction machine is reduced, and then noise generated by vibration of the traction machine can be reduced.

    本申请公开了电梯技术领域的一种无机房电梯曳引机用降噪装置,包括降噪箱,所述降噪箱包括内箱和外箱,内箱和外箱之间留有空腔,所述内箱的底部设有多个避让通道,避让通道从内箱底部一直延伸至外箱的外底部,其中一个所述避让通道中设有支撑架,支撑架用于将曳引机固定在轿厢顶部,所述支撑架上固定连接有多个弹片,每个所述弹片远离支撑架的一端穿过避让通道的通道壁并位于空腔中,所述空腔中填充有清水。本方案通过以支撑架和弹片为介质,将曳引机产生的震动传递至空腔的清水中,通过弹片引起水的波动,如此就使得清水吸收了弹片的震动力,使得曳引机产生的震动力减小,进而就可以减小因为曳引机的震动而产生的噪音。
