Abstract
The utility model discloses a protection device for flexible flywheel circle of engine, include with flexible flywheel circle assorted disc and install centering shaft on the disc, the central point of disc puts to open there is the round hole, the round hole with the disc is all concentric with the center hole of the bent axle flange end of installation flexible flywheel circle, the cover has the one end of sealing washer to pass on centering shaft's the piston rod the round hole is fixed through the nut on the disc, leave the clearance of satisfying the sealing washer and rising and critically asking between sealing washer outer peripheral edges wall and the bent axle flange end center hole inner wall. Solved the phenomenon that causes the quality of engine flexibility flywheel circle signaling gear broken teeth, curved tooth at transit, flexible flywheel circle signaling gear plays fine protective action to the engine, consequently, has stopped the phenomenon that flexible flywheel enclosed signaling gear broken teeth, curved tooth, the effectual engine assembly assembly quality that has improved.
Description
Technical field
This utility model is related to engine flexible flywheel signal teeth preventer part field and in particular to one kind is used for
The protection device of engine flexible flywheel ring gear.
Background technology
The effect of engine flexible flywheel ring gear is in engine start, engages with starter motor, passes starting mechanomotive force
It is delivered on the connector of bent axle, realize the power transmission between starter motor and bent axle, reach the purpose starting electromotor.Electromotor
On the ring flange of engine crankshaft rear end, the gear ring on flywheel provides signals to revolution speed sensing to the installation site of flexible flywheel gear ring
Device, speed probe again signal transmission give ECU, ECU receive signal just control oil spout light a fire, without receiving signal, just
Igniting will not be controlled, electromotor cannot start.Engine assembly through offline lifting, logistics transportation reach general assembly factory when, this phase
Between might have some links cause the tooth of engine flexible flywheel ring gear knock curved, touch disconnected, cause engine flexible flywheel ring gear
The phenomenon of signal teeth broken teeth, leads to electromotor cannot start.
Content of the invention
The purpose of this utility model is aiming at the deficiency of above-mentioned technology, provides one kind to be used for engine flexible flywheel ring gear
Protection device, solve the phenomenon causing in transit engine flexible flywheel ring gear signal teeth broken teeth, soft to electromotor
Property flywheel ring gear signal teeth plays good protective action.
For achieving the above object, the protection device for engine flexible flywheel ring gear designed by this utility model, bag
Include the disk matching with flexible flywheel gear ring and be arranged on centration axis on described disk, the center of described disk has
Circular hole, described circular hole and described disk are all concentric with the center hole at the crankshaft flange end installing flexible flywheel gear ring, described fixed
One end that the upper cover of piston rod of heart axle has sealing ring is passed through described circular hole and is fixed on described disk by nut, described sealing
The gap meeting the requirement of sealing ring tensioner is left between circle outer peripheral wall and crankshaft flange end center hole inwall.
Further, described disk has some lightening holes.
Further, it is lined with pad between described nut and described disk.
Compared with prior art, this utility model has advantages below：Solve and cause in transit engine flexible
Flywheel ring gear signal teeth broken teeth, the phenomenon of the quality of curved tooth, play good protection to engine flexible flywheel ring gear signal teeth
Effect, therefore, has prevented flexible flywheel gear ring signal teeth broken teeth, the phenomenon of curved tooth, effectively raises engine assembly assembling
Quality.
Brief description
Fig. 1 is the structural representation of the protection device that this practicality is used for engine flexible flywheel ring gear；
Fig. 2 is disc structure schematic diagram in Fig. 1；
Fig. 3 is centration axis structural representation in Fig. 1.
The each part numbers of in figure are as follows：
Disk 1, circular hole 2, lightening hole 3, centration axis 4, handle 5, piston rod 6, sealing ring 7.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
It is illustrated in figure 1 the protection device for engine flexible flywheel ring gear, in conjunction with shown in Fig. 2, fly including with flexibility
The wheel disk 1 that matches of gear ring and be arranged on centration axis 4 on disk 1, whole flexible flywheel gear ring is covered by disk 1, in addition,
In view of light-weighted requirement, the material selected by disk 1 is polyurethane, and on the premise of ensureing disk 1 intensity, in disk
Some lightening hole 3 is offered with duplicate removal on 1.
In conjunction with shown in Fig. 3, the center of disk 1 has a circular hole 2, circular hole 2 and disk 1 all with flexible flywheel gear ring is installed
Crankshaft flange end center hole with one heart, one end that the piston rod 6 of centration axis 4 is cased with sealing ring 7 passes through circular hole 2 and passes through
Nut is fixed on disk 1, thus centration axis 4 are installed on disk 1, in addition, being lined with pad between nut and disk；In order to
The tensioner meeting sealing ring requires, and the external diameter of sealing ring 7 will match with the internal diameter of crankshaft flange end center hole, i.e. sealing ring
Outer peripheral wall and center hole inwall between gap can not be too big nor too little, during sealing ring tensioner, sealing ring is close to
On the inwall of center hole, when sealing ring resets, between the outer peripheral wall of sealing ring and center hole inwall, leave gap, side
Just centration axis depart from the center hole at crankshaft flange end.
Flexible flywheel gear ring is arranged on crankshaft flange end, and the position assembled according to it, with the center at crankshaft flange end
Circular hole, as internal point, one end that the piston rod 6 of centration axis 4 is cased with sealing ring 7 is inserted in center hole so that feeling relieved
What axle 4 was contacted with center hole is the sealing ring 7 of polyurethane material, and the protection device for engine flexible flywheel ring gear puts
After flexible flywheel gear ring, centration axis are positioned at the center hole at crankshaft flange end.
The handle 5 of centration axis 4 pushes about 90 degree, and the eccentric block being connected with handle 5 drives piston rod tension blind rivet, blind rivet
Compression sealing ring 7, the diameter of sealing ring 7 is subject to buckling big, and tightly tensioner is in centering in the hole, sealing ring 7 and center hole hole wall
Frictional force, so that whole protection device is secured firmly on flexible flywheel gear ring, play good protective action, and, poly-
Urethane sealing ring does not result in the damage of center hole yet, and whole operation is simple, convenient and swift.When taking off whole protection device,
Only the handle 5 gently return of centration axis 4 need to be returned to the state before pushing, now piston rod 6 is descending, relieves to blind rivet
Tightening force, the thrust being applied on sealing ring 7 contacts therewith, and sealing ring restores to the original state, and there is gap and center hole between,
Whole protection device, departing from center hole, easily takes off whole protection device.Therefore, flexible flywheel gear ring is played good
Protective action, has prevented flexible flywheel gear ring signal teeth broken teeth, the quality phenomenon of curved tooth, effectively raises engine assembly dress
Aglycon amount.
