I think in order to do this, you'll need to know ahead of time the min/ 
max of all your sizes, and the min/max for each chart.  Then you can  
construct a setting for BubbleSizes that uses a common scale across  
the charts:

small = Table[{i, i, i}, {i, 10}];
smallSizes = small[[All, -1]];
big = Table[{i, i, i + 9}, {i, 10}];
bigSizes = big[[All, -1]];
min = Min[smallSizes, bigSizes];
max = Max[smallSizes, bigSizes];
size = Rescale[#, {min, max}, {0.05, 0.2}] &;
BubbleChart[small,
  BubbleSizes -> {size[Min[smallSizes]], size[Max[smallSizes]]}]
BubbleChart[big, BubbleSizes -> {size[Min[bigSizes]],  
size[Max[bigSizes]]}]

This works for me:

BubbleChart[RandomReal[1, {10, 3}], Axes -> True, Frame -> False,
  Ticks -> {Range[0, 1, 0.1], Range[0, 1, 0.05]}]

Can you give an example that isn't working?
