SMR Gearbox Set up
Satisfactory overall performance is determined by appropriate set up. lubrication and servicing. hence it is necessary that the directions inside the installation and servicing leaflet. provided with each gearbox. are followed meticulously. several of the important aspects of belt and torque-arm set up are listed under.
one. Install pulley on gearbox input shaft as near to your reducer achievable, and mount reducer on driven shaft as near to bearing as useful. failure to perform this will likely lead to extra loads within the input shaft bearings and output bearings and could bring about their premature failure.
two. Install motor and wedge belt drive together with the belt pull at approximately 90° to the center line amongst driven and input shafts. this will likely permit tensioning from the wedge belt drive with the torque arm which must ideally be in tension. if output hub runs anti-clockwise. torque arm needs to be positioned the proper.
3. lnstall torque-arm fulcrum on the rigid help to ensure that the torque-arm will likely be at somewhere around proper angles for the center line with the driven shaft as well as the torque arm case bolt. make certain there is sufficient take up from the turnbuckle for belt stress adjustment.
Continue to keep near.
Bell drive can be found in any convenient postion. when the torque arm would be to be used to tighten the belts, the drive must be at about tight angle to your line involving the input and output shafts.
Bell drive could be located to the proper if desired.
If output hub rotates clock-wise. position belt drive and torque arm in opposite path to that shown during the illustration.
