The side of the output shaft I is provided with auxiliary-motor, the axis of the output shaft II of the auxiliary-motor is parallel to output
The axis of axis I is provided with sliding block in the bottom of auxiliary-motor, and the sliding block and sliding slot cooperate；
The screw rod that axis is parallel to the extending direction of sliding slot, one end of the screw rod and the envelope of sliding slot are provided in sliding slot
Closed end rotation connection, the other end of screw rod is located on the outside of sliding slot after passing through sliding block, and screw rod is threadedly coupled with sliding block；
Side on output shaft I close to water pump is socketed with driven gear, is socketed with driving gear on output shaft II, turns
Dynamic screw rod keeps sliding block mobile with auxiliary-motor, driven gear can be made to engage with driving gear.
According to actual use operating condition, whether selectivity is engaged driven gear with driving gear.
When operating condition is harsh, screw rod is rotated, so that sliding block is mobile to output shaft I, until driven gear is nibbled with driving gear
It closes, then starts decelerating motor and auxiliary-motor, so that output shaft I and output shaft II rotate, and its direction of rotation is engaged in gear
Position is opposite.When pumping the leaf fluid blockage to be driven inside pipeline, auxiliary-motor passes through driving gear and driven gear
One thrust is increased to output shaft I, offsets the torque that a part is generated by line clogging, then to improve I both ends of output shaft
Synchronism, the case where then preventing motor output shaft from being twisted off appearance.
Further, the sliding slot is dovetail groove, and its opening size is less than slot bottom size, and the sliding block is trapezoid block,
The geomery of cross section of geomery and sliding slot of its trapezoidal faces is consistent, and the slot in the face and sliding slot where the bottom of sliding block
Bottom contact.
Compared with prior art, the present invention having the following advantages and benefits:
The device that the present invention avoids pump motor output shaft from twisting off, auxiliary-motor is by driving gear and driven gear to defeated
Shaft I increases a thrust, offsets the torque that a part is generated by line clogging, then to improve the synchronization at I both ends of output shaft
Property, the case where then preventing motor output shaft from being twisted off appearance.
