Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 2-4, the disengaging type motor driver comprises motor 1, motor output shaft 11 and driven wheel 2, be arranged with successively driven wheel 2 on the motor output shaft 11, back-up ring 3 and base 4, back-up ring 3 comprises the disk 31 that is fixedly connected with driven wheel 2 and is arranged on vertically the block 32 at disk 31 edges, base 4 is housed in the block 32, radially have cotter way 41 on the base 4, be provided with in the cotter way 41 and can be thrown away the removable pin 42 that cooperates with block 32 by centrifugal force, the removable pin 42 outer back-moving springs 43 that are arranged with, driven wheel 2 and back-up ring 3 are flexibly connected with motor output shaft 11, and base 4 is fixedly connected with motor output shaft 11.
Referring to Fig. 5, Fig. 5 is the cutaway view of base before the motor-driven, and this moment, removable pin 42 and back-moving spring 43 were housed in the cotter way 41 of base 4.After motor 1 drove, motor output shaft 11 rotated.Because motor output shaft 11 is fixedly connected with base 4, motor output shaft 11 and driven wheel 2 flexible connections, so motor output shaft 11 directly drives base 4 and rotates together, during initial condition, driven wheel 2 is with respect to motor output shaft 11 transfixions.Referring to Fig. 6, Fig. 6 is the cutaway view of motor-driven rear base again.After base 4 rotated, removable pin 42 was along with the centrifugal force of motor output shaft 11 is thrown out of cotter way 41, and this moment, back-moving spring 43 was compressed.The removable pin 42 that is thrown out of contacts with block 32, rotates together thereby drive block 32.Because disk 31 is fixedly connected with driven wheel 2, driven wheel 2 rotates with back-up ring 3 again.At this moment, motor 1 by motor output shaft 11, base 4, removable pin 42, block 32 and disk 31 with transmission of power to driven wheel 2.
When motor 1 stopped to drive, motor output shaft 11 and base 4 stopped operating, and centrifugal force disappears, and removable pin 42 is returned in the cotter way 41 under the effect of back-moving spring 43.At this moment, back-up ring 3 and driven wheel 2 are not subject to the active force of removable pin 42, disconnect between driven wheel 2 and the motor 1.Operating personnel can manually drive the rotation of driven wheel 2, realize electronic to manual switching.
