4. braked wheel 30 peripheries are the brake band 32 that brake arm 31 is handled, and the braking and the washing running of turning round that be used for dewatering stops; The reverse non-return torsion spring 27 that is then overlapped by dehydrating shaft 24 of following stops.
5.NGW type epicyclic train reducing gear 23 is incorporated into week in the braked wheel 30 with its internal gear.
The main not enough point that this clutch exists is as follows:
1) the coaxial rotary system of dehydration is fastened successively and is formed by dehydrating shaft, braked wheel, tooth shell, and the axiality of assembly technology requires high.
2) reducing gear places in the tooth shell and the brake disc in the middle of the dehydrating shaft of the coaxial rotary system of dehydration, causes the processing request height of the coaxial rotary system of whole dehydration, and assembly technology is complicated, the manufacturing cost height.
3) non-return torsion spring poor reliability.
Summary of the invention
