Furthermore, at least 1 limiting groove and at least 1 limiting buckle are adopted; when both of them adopt a plurality of, it is a plurality of spacing groove with spacing buckle is equal even interval arrangement in circumference.

Has the advantages that:

the utility model provides a novel crank bowl group, wherein a buffering reinforcing pad is sleeved on a bowl and is clamped with the bowl, and meanwhile, a bearing is sleeved in the buffering reinforcing pad; wherein, because this buffering reinforcing pad and this bowl circumference joint, so reduced this buffering reinforcing pad and inside and outside the relative rotation between the both sides subassembly with rock, reduced simultaneously and the both sides subassembly between relative friction, also reduced wearing and tearing each other to the life of crank bowl group has been improved.

Therefore, compared with the prior art, the crank bowl group reduces the abrasion among components and prolongs the service life of the bowl group.
