ANALYSIS OF RESULTS
Graphs were plotted for the data from tests 15 thru 17 and 18 thru 21. Having determined the general shape of the curves, curve firts were performed mathematically:
Test 15 - Msaraka Dry
D + deltaD = 16.39 + 0.067 t (r2= 0.978)
For L, shaft diameter, F and N constant
Test 16 - Msaraka Dry
D = 20.30 (L) exp (-1.026) (r2=0.997)
For shaft diameter, F, N , t constant
Test 17 - Msaraka Dry
D = 0.00339 (N) exp (1.034) (r2 = 0.997)
For L, shaft diamater, F, t constant
Test 19 - Msaraka greased
D + deltaD = 16.19 + 0.0291 t (r2 = 0.979)
For L, shaft diamater, F, N constant
Test 20 - Msaraka greased
D = 10.30 (L)exp(-1.012) (r2=1.000)
For shaft diamater, F, N , t constant
Test 21 - Msaraka greased
D = 0.00137 (N) exp (1.049) (r2=0.997)
From the above results it can be concluded that, after an initial period of rapid wear,
DeltaD is proportional to N.T / L
