ECCENTRIC MOTOR

摘要

The eccentric motor has a motor housing with an internal cylinder space. A main shaft is concentrically aligned with a central axis of the cylindrical space. A rotary blade is rigidly fixed, and arranged radially with respect, to the main shaft. A rotor is eccentrically arranged inside the motor housing, wherein the rotational axis of the rotor is spaced at a predetermined distance of eccentricity from the central axis of the main sheath surface of the motor housing. The rotary blade and the rotor are coupled to each other through a coupling member to establish a forced mechanical connection therebetween. The coupling member is adapted to move relative to the rotary blade in a direction parallel to the longitudinal axis thereof, and also relative to the rotor in a direction perpendicular to the longitudinal axis of the rotary blade.

1. An eccentric motor (10) comprising
a motor housing (11) having an internal cylinder space (12) of substantially cylindrical shape, a main shaft (F) concentrically aligned with a geometrical central axis (T1) of the cylindrical space (12) of the motor housing (11), said main shaft (F) being led through at least one of the terminal cylinder lids of the motor housing (11) by means of bearing, at least one rotary blade (13, 13′) rigidly fixed to the main shaft (F) and arranged radially with respect to the main shaft (F), wherein the envelop surface (13a) of the outer end portion of the rotating blade (13, 13′) has the same circumferential arc as that of an inner main sheath surface (23) of the motor housing (11), said envelop surface (13a) leaning against said inner main sheath surface (23) in a flexible manner, at least one inlet port (31) and at least one outlet port (32), both formed in the motor housing (11), a rotor (18) eccentrically arranged inside the motor housing (11), wherein the rotational axis (T2) of the rotor (18) is spaced at a predetermined distance of eccentricity (X) from the geometrical central axis (T1) of the main sheath surface (23) of the motor housing (11), wherein said rotor (18) is coupled to said terminal cylinder lids of the motor housing (11) by means of bearing and adapted to rotate around its rotational axis (T2), and wherein within the rotor (18) a clearance of specific width (W) is formed for each of the rotary blades (13, 13′), said clearance being separated from the working space of the motor by a sealing and closing mechanism, and wherein the rotor (18) or said sealing and closing mechanism is seated into the main sheath surface (23) of the motor housing (11) and aligned with the motor housing (11) along a concealed sheath surface (24) in a sealed manner, characterized by that the at least one rotary blade (13, 13′) and the rotor (18) are coupled to each other through a coupling member (20) to establish a forced mechanical connection therebetween, said coupling member being adapted to move relatively to the rotary blade (13, 13′) in a direction parallel to the longitudinal axis (L) thereof, and also relatively to the rotor (18) in a direction perpendicular to the longitudinal axis (L) of the rotating blade (13, 13′).
