Polygon Hard-Tooth-Faced Gearbox
Aug 20, 2018

    Feature and Applicable Scope

  The Polygon Hard-Tooth-Faced Gearbox from SR Co. Are divided into two series i.e. Parallel-shaft cylindrical helical-gear speed reducers and orthogonal-shaft spiral bevel gear cylinder helical-gear reducers,can be widely used in metallurgy,mine,transportation,energy source,cement,building,chemical,textile,light industry,etc.

  Main feature of polygon hard-tooth-faced gearbox:

  1.Optimizing design is made on the gears for hard-tooth-faced gearbox in the national standard,and the actual bearing capability of some speed reducers is improved.

  2.The box-type design has broken through the thinking model in which the hard-tooth-faced gearboxes are led by curves in the national standard,and has introduced a shape of polygon led by straight lines.

  3.The polygon boxes can be mounted in any way and are adaptive widely.

  4.Small volume,light weight,low noise,high efficiency and long service life.

  Introduction on polygon hard-tooth-faced gearbox:

  1.Parallel-shaft series:include the following types:1-step geared ones,with 18 stand no.s,14 nominal gear ratios in range of 1.25-6.3:2-step geared ones,with 17 stand no.s,11nominal gear ratios in range of 6.3-20:3-step geared ones,with 14 stand no.s,14 nominal gear ratios in range of 22.4-100:4-step geared ones,with 11 stand no.s,14 nominal gear ratios in range of 112-500.The 2-4 step geared reducers have three outputting ways,i.e.solid-shaft,straight-key hollow-shaft and shrinkage-disk hollow shaft;three mounting ways as developed base Mounted,bottom surface installation,top surface installation,install on the right,install on the left,the installation in the front surface,the installation on the behind surface;each surface have four kinds of installed position from 1-4,can combine into more than thirty thousand types of polygon parallel-shaft hard-tooth-faced Speed Reducers.

  2.Orthogonal-shaft series:include the following types:2-step geared ones,with 18 stand no.s,5 nominal gear ratio in range of 8-14;3-step geared ones,with 14 stand no.s,11 nominal gear ratio in range of 16-50;4-step geared ones,with 14 stand no.s,17 nominal gear ratio in range of 56-355.All the 2-4-step geared reducers have three outputting ways,i.e.solid-shaft,straight-key hollow shaft and shrinkage-disk hollow-shaft;bottom surface installation,top surface installation,install on the right,install on the left,the installation in the front surface,the installation on the behind surface;each surface have eight kinds of installation position from 1-8,can combine into more than thirty thousand types of polygon parallel-shaft hard-tooth-faced Speed Reducers.

  Application conditions for polygon hard-tooth-faced gearboxes:

  1.The peripheral speed of gear transmission of the gearbox is no more than 20m/s;and the speed of high-speed shaft is no more than 1500r/min.

  2.The operation ambient temperature of reducer is -40℃-+45℃(when it is lower than 0℃,one should heat the lube up to be more then 0℃ before starting).

  3.The reducers can run both CW and CCW direction in principle.
