where [P.sub.sa/pl], [P.sub.ax/sa], [P.sub.sa/sh], and [P.sub.pl/sh] correspond to the part of the power dissipated between the two satellite and planetary bevel pinions, the satellite pinion and the satellite-carrier axis, between the two bevel heads of the satellite pinions and the surrounding plastic shell, and the two bevel heads of the planetary pinions and the surrounding plastic shell (see Figure 3).
Power Dissipated between Two Satellite Bevel Pinions and Two Planetary Bevel Pinions.
Note that a yield [[eta].sub.sa/pl], with a nonzero value (i.e., [[eta].sub.sa/pl] > 0), occurs between the two satellite pinions and two planetary pinions only when the angular velocity differs between the driven wheels; that is, [DELTA][omega] > 0.
Power Dissipated between the Satellite Bevel Pinions and the Plastic Shell.
The pinion for these machines is of the type shown in figure 2.
Starting from the construction of the pinion shown in figure 2, a variant may be made, which to allow for the back turn clearance to be compensated when it is necessary only, therefore in milling operations and in accurate positioning.
The main pinion 1 and the second pinion 2 are coupled by bolts 3.
Force [F.sub.A] is so dimensioned as to provide for the permanent clearance compensation, whatever the instantaneous value of the moment reduced to the pinion level.
For the calculation, design and construction of the new pinion information and formulas from sources [3] and [4] were used.
However, this pinion design is not intended for standard cars, which means that the options are rather limited here.
The conclusion from the analysis is that the steering pinion represents the only acceptable route for dealing with the issue.
