Description
Technical field
The present invention relates to crankshaft vibration damper field, relates in particular to the efficient vibration damping knot of power section in 3 D measuring instrument
Structure.
Background technology
Bent axle is the important component in engine, and it bears the power that connecting rod transmits, and is transformed into torque and passes through bent axle
Export and drive other annexes on engine to work.In engine working process, through connecting rod is transmitted to the active force of crank-pin
It is in periodically to change that size and Orientation, which is, and this periodically variable power is acted on bent axle, causes crank throw to turn round instantaneous
Angular speed is also in cyclically-varying.Because the Rotary Inertia of Flywheel being packed on bent axle is big, its instantaneous angular velocity can substantially be seen
Work is uniform.So, crank throw sometimes will turn soon than flywheel, sometimes turn slowly than flywheel again, formed relative to flywheel
Torsionoscillation, that is, the twisting vibration of bent axle, when excitation force frequency and the bent axle natural frequency of vibration are into integral multiple, crankshaft torsion shakes
It is dynamic just to aggravate because of resonance.This will make engine power incur loss, gear or chain wear increase, even by bent axle when serious
Twist off.It is an entirety that it is Nian Jie that rubber is fully relied between the inner ring of existing crankshaft vibration damper and outer ring, by gluing of surfaces
The influence of the factors such as flatness, the performance of adhesives, it is bonding and unstable between rubber and inner ring, outer ring, in bent axle
Under twisting vibration, being bonded easily failure causes the major quality that rubber blanket skids between Internal and external cycle, even causes outer ring to fly off
Problem.
The content of the invention
It is an object of the invention to provide the efficient vibration-proof structure of power section in 3 D measuring instrument, to solve in the prior art
The problem of outer ring of crankshaft vibration damper may be flown off because of adhesive failure.
The present invention is achieved through the following technical solutions：
The efficient vibration-proof structure of power section in 3 D measuring instrument, including outer ring, inner ring, wheel hub, and be adhered to described outer
Rubber blanket between circle and inner ring, the inner surface of the outer ring and the outer surface of inner ring are provided with the multiple phases circumferentially surrounded
Mutually parallel annular groove, there is the projection to match with the annular groove on the rubber blanket.Subtract for existing bent axle
It is Nian Jie connected that rubber is fully relied between shake device inner ring and outer ring, once easily cause outer ring to fly off if adhesive failure the problem of,
The present invention proposes the efficient vibration-proof structure of power section in 3 D measuring instrument, by the inner surface of the outer ring and the appearance of inner ring
Face sets annular groove, then enable to be filled in annular groove by the projection in rubber blanket between inner ring, outer ring,
It is brought into close contact with the inner surface of annular groove so that rubber blanket limits mutually with annular groove, even if rubber blanket and inner ring, outer ring
Between adhesive failure, the rubber blanket is relatively fixed in the presence of the annular groove to match with inner ring with inner ring, so as to
By the effect of the annular groove to match with the outer ring, limit the motion of outer ring vertically, avoid rubber blanket with it is outer
The problem of outer ring may be flown off after adhesive failure between circle.The annular groove is multiple, i.e., the described projection that is parallel to each other
Also should have it is multiple, to match with annular groove.By multiple annular grooves and filling multiple projections therein, to carry
For bigger limitation, the possibility for avoiding outer ring to fly off to a greater extent.
Preferably, the annular groove number of the outer surface of the inner surface of the outer ring and inner ring is 2 or 3.Annular is recessed
Groove sets that quantity may excessively cause outer ring or inner ring integral thickness is thinning, weakened, influence the intensity of crankshaft vibration damper with
Service life.Therefore the annular groove number of control inner ring and outer ring is only at 2 to 3, to fly in the stronger anti-outer ring of guarantee
The intensity of crankshaft vibration damper in itself is not influenceed as far as possible in the case of de- ability.
Further, the rough surface of the annular groove is uneven.Hackly surface can be by making shock-proof crank
The raw metal of device body directly obtained without grinding process or artificial spot welding or set using other manner and
Come.By setting the surface of the annular groove rough, to increase the friction system between annular groove and rubber blanket
Number, to provide bigger frictional resistance after adhesive failure, further avoids outer ring is possible from flying off.
Further, some waist-shaped holes are provided with the wheel hub.Wheel hub is the common components of crankshaft vibration damper, is used for
Connect bent axle, conveying is reversed.Waist-shaped hole is set on wheel hub, to mitigate the weight of crankshaft vibration damper, reduces its rotator inertia, together
When reduce and outer coupling portion between frictional resistance, reduce equipment attrition.
Further, the waist-shaped hole is provided with three or four, and the center annular around the wheel hub is uniform.Waist-shaped hole number
Amount may excessively cause wheel hub insufficient strength, therefore set waist-shaped hole quantity only three or four, by it around the center of wheel hub
It is uniformly distributed, to ensure that wheel hub Mass Distribution is uniform, center of gravity is i.e. centrally located, it is ensured that each orientation is suffered in the course of work centrifuges
Power distributing equilibrium, avoid because the situation that unbalance stress causes bonding to be failed since local.
The present invention compared with prior art, has the following advantages and advantages：
1st, the efficient vibration-proof structure of power section in 3 D measuring instrument of the present invention, by outer ring inner surface and inner ring it is outer
Surface sets annular groove, and is set on rubber blanket with the projection to match with annular groove so that rubber blanket and annular
Groove is limited mutually, and the surface of annular groove is arranged into hackly surface with increasing friction force, even if rubber blanket
Adhesive failure between inner ring, outer ring, the rubber blanket is in the presence of the annular groove to match with inner ring, with inner ring phase
To fixation, so as to by the effect of the annular groove to match with outer ring, limit the motion of outer ring vertically, avoid rubber
The problem of outer ring may be flown off after adhesive failure between pad and outer ring.
2nd, the efficient vibration-proof structure of power section in 3 D measuring instrument of the present invention, by by the inner surface and inner ring of the outer ring
The annular groove number of outer surface be disposed as 2 or 3, realize in the case where ensureing that stronger anti-outer ring flies off ability to the greatest extent
Amount does not influence the intensity of crankshaft vibration damper in itself.
3rd, a kind of crankshaft vibration damper for preventing that outer ring from flying off of the present invention, the waist-shaped hole around hub centre is set on wheel hub,
To mitigate the weight of crankshaft vibration damper, its rotator inertia is reduced, while reduces the frictional resistance between outer coupling portion, drop
Low equipment attrition；By the way that waist-shaped hole is uniformly distributed, it is ensured that centrifugal force distributing equilibrium suffered by each orientation in the course of work, avoid because
Cause the situation of bonding failure since local for unbalance stress.
