Embodiment 1）
[0016] See figure 1 , The traction motor recovery control system of this embodiment includes a screw gear 1, a screw mandrel 2, a baffle plate 3, a return spring 4, a block 5, a friction wheel 6, a friction block 7 and a compression spring 8.
[0017] The screw gear 1 is set as one of the first-stage reduction gears of the traction motor, and is threadedly connected with the screw mandrel 2 . The upper gear of screw gear 1 and the gear meshed with it are all helical gears. Screw mandrel 2 is fixed in the gear box of traction motor. The block 5 is arranged on the outer wall of the balance wheel 9 of the traction motor. The baffle 3 is slidably connected with the screw mandrel 2 and the rotating shaft of another reduction gear of the traction motor, and one end of the baffle 3 extends to the bottom of the block 6 . The return spring 4 is sleeved on the screw mandrel 2 and is located above the baffle plate 3 . The friction wheel 6 is fixed on one of the first-stage reduction ...

The invention discloses a resetting control system for a traction motor. The resetting control system comprises a screw rod gear, a screw rod, a baffle, a return spring and a stop block. The screw rod gear is arranged to be a primary reduction gear in the traction motor and is in threaded connection with the screw rod, the screw rod is fixed in a gearbox of the traction motor, the stop block is arranged on the outer wall of a balance wheel of the traction motor, the baffle is connected with the screw rod and a rotating shaft of the other reduction gear of the traction motor in a sliding mode, one end of the baffle extends to the position below the stop block, and the return spring is arranged on the screw rod in a sleeving mode and located above the baffle. The screw rod gear is in threaded connection with the screw rod, and when the motor operates, the screw rod gear ascends along the screw rod and pushes the baffle to the upside to finish the traction movement; when the motor stalls, the screw rod gear descends under the action of the return spring so that a tractor can be reset. The resetting control system is simple in structure, reliable in movement, convenient to assemble and low in production cost, and the number of the parts is small.
Description
technical field [0001] The invention relates to a traction motor recovery control system. Background technique [0002] The traction motor is mainly used in the tractor to control the drainage of the washing machine, and is the main part of the tractor. The tractor has a power-off recovery function, that is, after power failure, the traction motor stops working. At this time, the traction motor restores the control system to complete the reset of the tractor, so that the traction rope of the tractor returns to the initial state and waits for the next traction action. . [0003] At present, the recovery control system of the traction motor is mainly realized by a sector gear plate driven by a return tension spring and gear cups, magnets and other components matched therewith. This kind of system has a complex structure, and in actual work, the frictional resistance is relatively large, and the problem of "non-return" is prone to occur, and the number of parts is large, and ...
