<p>a. Improvements made to speed reducers. b. Characterised by the installation of one of the toothed wheels inside the other, the latter being hollow and open laterally for this purpose, there being formed between the inner periphery of the enveloping wheel and the outer periphery of the internal wheel, a sufficient space for housing the toothed ring gear associated with this second wheel, this all being so that the engagements between the four components are situated exactly in the same plane as the rolling surface which connects the wheels in question to the crank. c. The invention relates to improvements made to speed reducers. <IMAGE></p> |
