vladoniki Posted May 21, 2010 Posted May 21, 2010 Hello friends! I would like to ask you for information about Technic Differential with One Gear 28 Tooth Bevel. Does someone know why in the middle it has a crack/cleft? The middle part of it holds two of the cog-wheels, but i don't see any use of the cleft... A picture of the diff and the cleft is marked. Thanks to all! Quote

The pin in the middle support one of the gears (often called the spider gear). The other part is basically a stop. It keeps the spider gear from falling out and it keeps you from pushing in the axles on the other two gears too far. Quote
Frequency Posted May 21, 2010 Posted May 21, 2010 i wonder if by having that slot there that the amount of material comprising the cleft would be the same as 1 mini bevel gear therefore ensuring more even mass around the axis of rotation Quote

More likely the opening is simply to save weight (and ABS) compared to having it solid. The taper is a draft angle to allow removal of the part from the mold. Quote
