DBY series Transmission
Gearbox
1. 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.
2. Performance & characteristics:
High
bearing capacity, low noise, small volume, light weight, high
efficiency, and long service life.
3. 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.
4.
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.
5. Model
It consists of model, nominal center distance a (last grade center
distance), nominal transmission ration, assembly model, and input
shaft rotation direction code.
6. 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.
