The cause of noise huge

底盤采用箱形結構，不是所有焊縫都進行連續焊接，各個底盤焊縫的長短、高低位置不同，底盤剛性存在較大個體差異，有的則產生共鳴效應，機器如有一點震動噪聲就被放大；底盤由鋼板焊成，不具備吸震消聲功能，如果其固有頻率與齒輪嚙合頻率接近就可能造成個別機器因齒輪弱小震動引發較大共震，引起噪聲值上升。

Chassis adopts box type structure, not all welds are continuous welding, various chassis weld length, height, there are great individual differences in the chassis rigidity, others resonate effect, machines such as a little vibration noise is amplified; the chassis by the steel plate welded, does not have the shock-absorbing silencing function, if close to its inherent frequency and gear meshing frequency may cause individual machines for gear weak vibration lead to greater resonance, noise caused by increased.

Classification and characteristics

卷揚機的分類及其不同特性卷揚機包括建筑卷揚機，同軸卷揚機 主要產品有：JM電控慢速大噸位卷揚機、JM電控慢速卷揚機、JK電控高速卷揚機、 JKL手控快速溜放卷揚機、2JKL手控雙快溜放卷揚機、電控手控兩用卷揚機、JT調速卷揚機、KDJ微型卷揚機等，僅能在地上使用，可以通過修改用于船上。它以電動機為動力，經彈性聯軸節，三級封閉式齒輪減速箱，牙嵌式聯軸節驅動卷筒，采用電磁制動。該產品通用性高、結構緊湊、體積小、重量輕、起重大、使用轉移方便，被廣泛應用于建筑、水利工程、林業、礦山、碼頭等的物料升降或平拖，還可作現代化電控自動作業線的配套設備。

The classification and the different characteristics of hoist winch includes building hoist, hoist the main products are: JM coaxial electric slow large tonnage hoist, JM electronic controlled slow winch, JK electronic controlled high-speed hoister, JKL manual fast humping windlass, 2JKL manual double quick humping hoister, electric control manual control hoist, JT speed winches, KDJ Mini winch, can only be used on the ground, can be modified for use on board. It takes a motor as power, through an elastic coupling, gear box of three stage closed type gear, tooth type coupling driven drum, the electromagnetic brake. The versatility of the product is high, has the advantages of compact structure, small volume, light weight, big, use convenient transfer, is widely used in construction, water conservancy, forestry, mining, port materials such as lifting or flat mop, ancillary equipment can be automatic line for modern electronic control.

Jm系列為齒輪減速機傳動卷揚機。主要用于卷揚、拉卸、推、拖重物。如各種大中型砼、鋼結構及機械設備的安裝和拆卸。適用于建筑安裝公司、礦區、工廠的土木建筑及安裝工程。

Jm series gear reducer drive hoist. Mainly used for hoisting, pull, push, unloading heavy towing. Such as the installation and removal of large and medium-sized concrete, steel structure and mechanical equipment. Applicable to civil building construction and installation company, factory, mine and installation engineering.
