Embodiment

Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

The motor drive mechanism that the utility model provides as Figure 1-3, this motor drive mechanism mainly comprises motor sub-assembly 1, driving wheel 2, driven wheel 3, driven axle 4, axle bed 5, sprocket wheel 7; Wherein motor sub-assembly 1 is firmly secured to the upper surface of base plate 6 by bolt or screw, and axle bed 5 is firmly secured on the base plate 6 by bolt or screw in the mode that runs through base plate 6, and motor sub-assembly 1 and axle bed 5 also can adopt other modes to be fixedly mounted on the base plate 6.Be respectively arranged with the be used for fixing fixed hole corresponding with motor sub-assembly 1 and axle bed 5 on the base plate 6.

Motor sub-assembly 1 comprises motor and the retarder that is packaged in the shell, and motor provides driving force for hangar system, and retarder is reduced to the high speed rotation of motor output required output speed and enough output torques are provided.Shell is provided with mounting hole or assembling set, is used for motor sub-assembly 1 is firmly secured to base plate 6 by bolt or screw.Reducer output shaft is arranged in the direction perpendicular to base plate 6 on the shell of motor sub-assembly 1, and this mode of wearing of reducer output shaft can provide enough big moment of torsion output capability, and held stationary rotates.Reducer output shaft adopts the shaft mode that goes up, its part of stretching out motor sub-assembly 1 shell top forms output shaft 1-1, and under forming below motor sub-assembly 1 shell shaft mouth 8, at following shaft mouth 8 places sealing cover 1-2 is set, following shaft mouth 8 is sealed, thereby prevent that the lubricant oil in the motor sub-assembly 1 from oozing out from shaft mouth 8 down, avoid the pollution of processing cloth that hangar system is promoted.On the last output shaft 1-1 driving wheel 2 is installed, the preferred keyway mode that adopts is assembled between driving wheel 2 and the last output shaft 1-1, also can adopt other modes to fixedly mount.

Driving wheel 2 matches with driven wheel 3, and the rotation that motor is exported is delivered on the driven wheel 3 from driving wheel 2, and the transmission of preferred employing engagement system also can be adopted other mode transmissions such as belt between driving wheel 2 and the driven wheel 3.Driven wheel 3 is installed on the upper end of driven axle 4, and the preferred keyway mode that adopts is assembled between driven wheel 3 and the driven axle 4, also can adopt other modes to fixedly mount.Driven axle 4 lower ends are equipped with sprocket wheel 7, and the preferred keyway mode that adopts is assembled between driven axle 4 and the sprocket wheel 7, also can adopt other modes to fixedly mount.
