Abstract: A pin tooth cycloid reducer and an industrial robot are provided. The pin tooth cycloid reducer includes: a first cycloid structure system and a second cycloid structure system, disposed in an axial direction, wherein the first cycloid structure system is sleeved on an eccentric shaft, and each cycloid structure system comprises at least one cycloid structure in the axial direction; where the cycloid structure includes: a cycloid disk, a plurality of pin teeth distributed circumferentially and a pin tooth housing, successively disposed from inside to outside in a radial direction; wherein the plurality of pin teeth are rotatably fixed to the pin tooth housing, and the cycloid disk engages with the plurality of pin teeth; wherein all pin tooth housings in the pin tooth cycloid reducer are coaxially disposed. Therefore, deceleration can be achieved.
