Abstract
This invention discloses a one-way clutch which meshing gear will not push out. It consists of drive gearshaft, friction sheet steel, friction sheet copper, moving sleeve, springs, fitting pins, moving filling pieces, flat filling pieces, snap rings and drive shell. Through matching the spur gear keys with hollow axle, the drive gearshaft is inserted into the expanding inside of the hollow axle in order to make the drive gearshaft move lengthwisely inside the drive gearshaft of the hollow axle. With the inner spiral keys on the inner surface of the drive shell, the drive gearshaft will rotate when progressing. The rotation can mesh the drive gear and big flywheels. The advantages are prolonging the life of one-way clutch and reducing the production cost and use-cost.
Description
Technical field
The starter motor that the present invention relates on the I. C. engine is made the field, refers more particularly to a kind of overrunning clutch with protection engaging tooth function.
Background technique
Overrunning clutch is the vitals of starter motor on the internal-combustion engine such as automobile, realizes the function of starter motor by it.Yet actuation gear and big flywheel apical tooth take place in existing overrunning clutch regular meeting, thereby cause the heavy wear of actuation gear.In order to prevent the apical tooth phenomenon, in the making of actuation gear, the general end Bevel that actuation gear is contacted with big flywheel; to reduce actuation gear and the big surface of contact of practising wheel; but in actual use, still through regular meeting the apical tooth phenomenon takes place, cause the polishing of actuation gear impaired.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of overrunning clutch that can effectively prevent the engaging gear apical tooth, to improve the starter motor working efficiency, increases the service life, and alleviates complete machine weight, reduces and produces and user cost.
The present invention realizes by following manner: a kind of overrunning clutch of avoiding the engaging gear apical tooth, by the driving gear axle, the friction steel disc, the friction copper sheet, movable sheath, spring, locating stud, removable insole pieces, flat gasket, snap ring and driving shell constitute, the copper sheet that wherein rubs is superimposed with the friction steel disc, be buckled into one by removable insole pieces and movable sheath, its outer end one of suit again drives shell, the inwall that drives shell is provided with internal thread spline, cooperate by the excircle tooth of internal thread spline with the friction copper sheet, the inner circumference of friction steel disc is gear shape, cooperate with the keyway on the movable sheath outer wall, the outer wall that drives shell is provided with reduction gear, it is characterized in that: it also comprises a hollow shaft and a push rod, establish corresponding straight-tooth spline at the hollow shaft inner peripheral wall, hollow shaft sleeve is on the driving gear axle, movable sheath is installed on the hollow shaft, cooperate by helical spline, push rod passes the axis of driving gear axle, and realize that by the draw-in groove that is located at the push rod termination and snap ring the driving gear axle locatees on push rod, coil tension spring is enclosed within on the push rod, and an end withstands on the termination of driving gear axle.
The inner chamber of hollow shaft is divided into three joints, is respectively the movable chamber of driving gear axle, telescopic spring chamber and push rod chamber, and the inwall in the movable chamber of driving gear axle is provided with the straight-tooth key, is inserted in to pass through straight key in the movable chamber of driving gear axle of hollow shaft and cooperate with hollow shaft.
The driving gear axle is a hollow shaft, and axle head also is provided with the straight-tooth key.
Its working principle is: during engine start, driving lever on the starter motor is dialled before with push rod, and hollow shaft drive driving gear axle is together moved ahead, make the friction copper sheet that is installed on the hollow shaft be subjected to squeeze frictional engagement with the friction steel disc, because driving shell and the motor of this moment are in static engagement, and the gear of friction copper sheet circumference rotates under the effect that drives the internal thread spline on the outer casing inner wall, this rotation is passed to the driving gear axle by hollow shaft, if the gear of the big flywheel circumference on the gear on this moment driving gear axle and the motor is just corresponding, then the driving gear axle makes smooth advances, realize that both mesh, actuating motor beginning is afterwards connected, the rotation torque of actuating motor is passed to the friction copper sheet by driving shell, the friction steel disc, hollow sleeve, to the driving gear axle, pilot engine smoothly at last.After actuating motor quit work, under the effect of the deboost that spring and internal thread spline produce, engaging gear broke away from big flywheel.
If meet the position, gear top of gear and big flywheel circumference on the driving gear axle, the driving gear axle can contract in the quill shaft of hollow shaft, rotation along with the driving gear axle, engaging gear rotates, to at once, under the effect of spring, advance the gear meshing on actuation gear and the big flywheel until engaging gear and big flywheel gear, so just avoid the apical tooth phenomenon, reduced the gear wear on the driving gear axle.
Because the present invention has solved the apical tooth phenomenon of actuation gear with big flywheel effectively, prolonged the working life of overrunning clutch greatly, reduced the cost of production of enterprise and user's user cost effectively, and simple in structure, reliable performance has good DEVELOPMENT PROSPECT.
