The invention discloses a spiral guide rail planet carrier rolling wheel type elevator ascending and descending driving device and relates to the elevator equipment manufacturing technical field. The spiral guide rail planet carrier rolling wheel type elevator ascending and descending driving device comprises a spiral guide rail which is provided with T-shaped threads; a planet carrier rolling wheel driving unit is arranged on the spiral guide rail in a penetrating mode; the planet carrier rolling wheel driving unit comprises a planet carrier which is arranged on the spiral guide rail through a center hole of the planet carrier in a penetrating mode and driven by a motor; a plurality of spiral rolling wheels which are in compression joint with the spiral guide rail are circumferentially arranged on the planet carrier. Compared with the prior art, the problems that the existing elevator ascending and descending driving device is low in ascending and descending speed and short in service life can be solved.
