Reduction gearbox design pdf


Bearing.6.6, bearing.9.7, bearing calculation.
The set of genes that define the single-stage spur gear unit unequivocally reflects this, with standardization imposing discrete values sets on most of them.
Bearing.1.3, bearing.1.3, conclusion and recommendation The critical features involved in reduction paris xl the design of the gear reduction system have been determined through the use of statics, strength, and fatigue analyses.It is known that designing of a reducer is an iterative process in which it is necessary to make some tentative choices and to determine which parts of the design are critical For example, the impact of certain choice of the coefficient of face width.Bearings The bearings are critical components that allow the system to move smoothly.Mass of gear (Kg).478.753, pressure angle (deg.) 20 20, the single stage reduction gearbox The single-stage spur gear unit we are considering in this work is highly standardized, both in terms of its layout and in terms of design of its gearings, shafts.Automotive, aerospace, machine tools, etc.) require low mass.Shaft 1 (Pinion Shaft) 391.74.274.023.275.236 191.Involute.5 65 264, diameter gear (mm) 142.035 275.418.Rating life (Hrs.) Static safety factor Frictional loss (W).The overall efficiency of the two gears.The first components analyzed were the gears.The parameters of for each gear.For wear, the safety factor was smaller, on the average safety factor range, indicating that our selection is good.Design of single stage reduction gearbox.A statics analysis had to be performed in order to find the reactions and determine the loads on the bearings.Two different planes had to be evaluated in order to.The bearings, the gears, the shaft, and the keys need to be designed and analyzed.Tangential force (N) reduction promod code Radial force (N) Axial force (N) Normal force (N) Velocity (m/s) Factor concours science po bordeaux annales of safety form pitting Factor of safety from tooth breakage Torque (Nm).They should also withstand loading in the radial direction and thrust in the axial direction.The determination of our safety factor under fatigue proves that the shaft will not fail and our selection is good.The gears have very large safety factors under bending, which indicates that our selection of materials is extremely safe and conservative.Shear Force and Bending Moment diagrams were developed in order to determine the maximum points.
Borrowing the statics analysis already performed on the bearings, the shafts were analyzed.
