Cylindrical gear reducer installed should be fixed on the basis of a stable level or base to the oil drainage grooves to be able to smooth exclude cooling air circulation smooth. Enhanced when transmission couplings projections or gear and sprocket drive, you should consider the installation of protective devices, the output shaft to withstand greater radial load should be used. 2, cylindrical gear reducer installed device is required provisions ensure that staff can easily close the oil standard oil drain plug, breather plug. Install the preparations are completed, should order a comprehensive check the accuracy of the location of the installation, the reliability of fasteners clamping installed fasteners should be flexible rotation. Reducer Splash lubrication oil pools in the run before the user must remove the vent plug and replace the vent plug. Cylindrical gear reducer installed to ensure that the the transmission center axis, error should not be greater than the amount of coupling the use of compensation, the specific details can refer to specific reducer models and specific requirements. Sound can prolong life and to get a good transmission efficiency. 4, cylindrical gear reducer output shaft in installing transmission parts, prohibited the use of a hammer percussion, the correct approach is to use the assembly fixture and the internal threads of the shaft end bolts pressed into the drive, or they may cause reducer damage of the internal parts. Not the best steel fixed coupling, resulting in early bearing damage due to class coupling improper installation, will cause unnecessary additional load, severe or even cause the output shaft fracture
