Description

ï&frac*4;ˆä¸€)、Usage: Cone/Cylindrical gear speed reducer (hereinafter briefly as reducer) is used in the driving device on the vertical direction of input and output shaft. It is mainly used in belt conveyer and various transportation machineries, as well as used in drive gear of universal machinery in fields of coal, metallurgy, mine, chemical, building material, light industry and petroleum, etc. ï&frac*4;ˆäºŒï&frac*4;‰ã€Performance & characteristics: High bearing capacity, low noise, small volume, light weight, high efficiency, and long service life. (三)、Parameter range: DBY, DBYK, and DBZ reducer has *2 specs, with nominal center distance **0mm, **0mm, **0mm, **4mm, **0mm, **0mm, **5mm, **5mm, **0mm, **0mm, **0mm, and **0mm respectively; each spec has five transmission ratios (8, *0, *1.2, *2.5, and *4), two directions of turning, four assembly types, forming **0 kinds of reducers. DCY, DCYK, and DCZ reducer has *5 specs, with nominal center distance **0mm, **0mm, **0mm, **4mm, **0mm, **0mm, **5mm, **5mm, **0mm, **0mm, **0mm, **0mm, **0mm, **0mm, and **0mm respectively; each spec has *1 transmission ratios (*6, *8, *0, *2.4, *5, *8, *1.5, *5.5, *0, *5, and *0), two directions of turning, four assembly types, forming **0 kinds of reducers. The reducer series meet all power demands of TD type and DX type belt conveyer and other transport machineries, and working scope of 0.**6.5m/s belt speed. (å››)、Structure: The first drive of speed reducer is Gleason spiral bevel gear, the second and third is involute cylindrical spiral gear. Lubrication of reducer: Generally, gear of reducer adopts splash lubrication and natural cooling. Only if the work balance temperature of reducer exceeds the set value and the load power exceeds thermal power P, circulating lubrication or sump lubrication with cooling tube is adopted. (五)、Model It consists of model, nominal center distance a (last grade center distance), nominal transmission ration, assembly model, and input shaft rotation direction code. (å…­)、Assembly type According to the output shaft, it can be classified into I, II, III, and IV four kinds. Type I and II are left and right output shafts; III and IV are left and right output shaft of removal brake.
