This gearbox is equipped with four identical tapered roll-er bearings (bore diameter 60 mm, series 323).

It is very impor-tant at this stage to select gear proportions which will facilitate accurate mouldings with minimum tendency for post moulding warpage or stress relief. The two stage reduction gearbox consists of three shafts and four gears (two driver gears, two driven gears). Design Specifications The company we work for has decided to develop a series of single reduction spur gearbox reducer. 17.1 COMMERCIAL GEARBOXES . DESIGN CALCULATIONS 4.1. Calculate the number of steps or speed reduction stages for this range. In a single-stage gear train, which consists of z1 and z2 numbers of teeth on the driver and driven gears, and their respective rotations, n1 & n2. The design was made to accommodate a power transfer of 30kw at a drive speed of 1500 rpm. The power source applies the torque T1 to the input shaft, driving it at speed 1 in the sense of the torque (clockwise here). II. Impact on Gearbox via Single-Stage Gearbox Example A single-stage helical gearbox was selected for the analysis. The gearbox is a single -stage, epicyclic design with four planets and an overall ratio of 5.8:1, often termed as a medium- or low-speed gearbox. Defining Shafts For systems of parallel shafts groups have to be used. A typical case would involve the design of the gearing for a hoist to raise a certain weight (W) ata uniform speed, when making use of a motor with a given horsepower (hp) run-ning at a given speed (rpm) and driving through a pinion with number of teeth Np, Fig. After considering the space requirements a two-stage constant speed reduction gearbox was decided. There were two aspects to the Gear Design which needed to be considered: 1: The geometry of the gears to allow for the needed power transmission. 2: The strength design of the gear to allow for the use a Grade 1 steel. Google Scholar 3. Fig. Stage selection.
