Zusammenfassung: | The utility model relates to a smooth pendulum -type pump (1) for carry liquid, for example lubricating oil, this smooth pendulum -type pump includes: casing (2), axle (3) and inner rotor (4) be connected through smooth pendulum (5) and external rotor (6), wherein, external rotor (6) are arranged in the portion of holding (7). Here, to the utility model discloses the important is, first contact surface (9) going on contacting with external rotor (6) of the portion of holding (7) go up and/or on external rotor (6) and second contact surface (10) that the portion of holding (7) goes on contacting on apply reduction friction and wear polymer coating (11). Can realize the supporting of low wearing and tearing and low energy consumption from this. |
