Taking into account the complex working environment: uneven physiognomy of deep-sea,wheel’s skid,low surrounding visibility and so on,I bring forward the dead reckoning based on the driven wheel.

Taking into account complex working environment: uneven physiognomy of deep-sea, wheel s skid, low visibility of surrounding and so on, dead reckoning based on driven wheel for localization was brought forward in this paper.

Taking into account of the complicated situation of uneven topography in deep-sea cobalt crust area,mining vehicle′s wheels frequently skidding,a dead reckoning position method has been designed based on driven wheel.

The traditional theory of the involute gearing,which omits the effect of the friction between teeth,considers provided the input torque of the driving gear of an involute gearing keeps constant,the output torque of its driven gear also keeps unchanged.

The results show that shrinking inner hole of driven gears is conducted by heating with protective atmosphere and cooling in the iron tube-shaped container for slowly cooling gears,the exceeded tolerance problem of inner hole of driven gears can be better solved,and 90% driven gears can meet the needs of technology reguirement of the production.

Effect of superfine Ni powder addition on the sintering process and final properties of driven gears was studied.

Driven gear cracking was found in repair.
