Abstract
The utility model relates to a knocking type electric spanner clutch. The utility model comprises a motor, a motor shaft, a flywheel, and a flywheel shaft. The utility model is characterized in that a pinion is arranged on the motor shaft; the pinion is engaged with a large gear; a groove is arranged on a shaft hole of the large gear; a friction belt is arranged inside the groove; the flywheel shaft is arranged inside the shaft hole of the large gear. The utility model has the advantages that the blockage and the rotation of the motor can be prevented, and the normal operation of the motor and other circuit elements can be protected.
Description
Technical field
The utility model relates to a kind of knocking type electric wrench, particularly a kind of knocking type electric wrench clutch.
Background technique
Widely used electric wrench is many in vehicle maintenance at present passes to flywheel with gear with motor power, since flywheel with the energy that gathers when axis discharges, when being twisted bolt locking, flywheel meeting moment stall, this moment, stall can take place in motor, produce especially big electric current, cause the damage of motor and other component, I am at the Chinese patent 00216188.5 of application on January 18th, 2000, a kind of technology contents of portable type electric wrench is disclosed, solved problem, but the stall problem of the motor of this patent can't solve also at the dismounting wheel bolt.
Summary of the invention
The purpose of this utility model is to solve motor meeting stall in the prior art, and produces especially big electric current, causes the problem of the damage of motor and other component.Technical solutions of the utility model design a kind of knocking type electric wrench clutch, comprise motor, motor shaft, flywheel, flywheel shaft, it is characterized in that: a small gear is arranged on the motor shaft, small gear and gearwheel engagement, fluted on the gearwheel axis hole, the friction band is arranged in the groove, and flywheel shaft is in the gearwheel axis hole.The utility model has the advantages that to prevent motor rotation blockage the normal operation of protection motor and other component.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise motor 1, motor shaft 2, flywheel 3, flywheel shaft 4 among the figure, it is characterized in that: a small gear 5 is arranged on the motor shaft 2, small gear 5 and gearwheel 6 engagements, fluted 7 on gearwheel 6 axis holes, there is friction to be with 8 in the groove 7, flywheel shaft 4 is in gearwheel 6 axis holes.After flywheel 3 turns to a setting rotating speed when using, impact block rotates, meet the eccentric mass on the main shaft, bump against the back and drive the main shaft rotation, when twisting bolt locking as quilt, flywheel 3 meeting moment stalls, but because motor shaft 2 is to be with 8 friction slip to be connected by the friction in the gearwheel 6 axis hole grooves 7 with flywheel 3, therefore when flywheel 3 moment stall, motor shaft 2 drives small gears 5 and rotates with gearwheel 6, the stall during by flywheel 3 moment stall owing to flywheel shaft 4, friction is with 8 can't drive flywheel shaft 4 rotations, gearwheel 6 dallies on flywheel shaft 4, makes motor 1 and flywheel shaft 4 be empty cover and breaks away from shape, can prevent motor 1 stall.
