Abstract
The utility model is related to a kind of reinforced parallel shields, and including neck bush and arm set, arm set is one end occluded ellipse cylinder, eccentric shaft neck bore are formed in blind end end face, integrally extension is formed with axial neck bush to the outer rim of journal hole, it is characterised in that：Inner surface integrated vulcanizing layer scuff-resistant coating is covered in neck set and arm.The utility model is used and integrally made by rubber mass, and pastes the anti-wear material of one layer of aramid fabric in its inner surface, simple for process; it is rational in infrastructure, it is convenient for disassembly and assembly, and crank arm and maneton are protected simultaneously; it is repaired in time after ensureing crankshaft wear, and improves the service life of bent axle.
Description
Technical field
The utility model belongs to a kind of protective cover field, especially a kind of reinforced parallel shield on bent axle.
Background technology
Bent axle widely uses in engineering machinery field, is an important parts on engine, material is by carbon
Made of plain structural steel or spheroidal graphite cast-iron, there are two significant points:Trunnion, connecting rod neck, (also having other).Trunnion is mounted
On cylinder body, connecting rod neck is connected with crank pin end pore, and connecting rod small end hole is connected with steam-cylinder piston, is a typical crank block
Mechanism.Bent axle is promoted within the engine by reciprocating piston, and linear reciprocating motion is converted into circular motion.It will bear
High-frequency percussion drives each portion's parts centered on it again, so burden of the bent axle in engine is very heavy, can incite somebody to action
It is known as the line shaft in engine.Generated power is transferred to beyond engine when bent axle is pistons work, and flywheel relies on
Inertia force promotes connecting rod and piston further through bent axle, them is made to carry out air inlet, compression, work done and exhaust work.Bent axle is also direct
Other parts, such as camshaft, water pump, fan, ignition distributor, petrol pump and lubricating oil pump are driven indirectly.
Bent axle can normal use depend on lubricating condition, bearing clearance bearing concentricity, trunnion concentricity and just
True guarantee etc..The reason for Crank shaft Damage be it is many, some damage be it is recoverable, but bent axle fracture after can not just repair
It is multiple.Bent axle fractureed in addition to the reason for quality of materials aspect, and general fracture location is often between trunnion and rod journal.
Every bent axle has several trunnion and pin neck, and crank arm is the connecting lever for connecting axle journal.Since each position is subject on same bent axle
Torsion and rotary force it is different, simultaneously because the variation of bearing supporting force and the variation of main shaft concentricity, can make on crank arm
Stress concentration.In addition crank arm is thiner than axle journal in itself, and adjacent main bearing journal clearance is excessive, especially after twice base bearing with
Preceding twice main bearing journal clearance is excessive, and fracture is frequently experienced in cylinder rod axle journal root (by taking six cylinder machines as an example).Have after bent axle flywheel,
Before have belt pulley, crankshaft two end stress is overweight, then circular runout is frequent.Impulse force during along with front and rear cylinder operation, so that
Crank arm fractures.There is no to crank arm and maneton integrated protective in the prior art.
Utility model content
It, can be with integrated protective crank the purpose of this utility model is to provide one kind to overcome the above-mentioned deficiency of the prior art
Arm and maneton, and convenient for disassembly and assembly, the reinforced parallel shield on bent axle.
The technical scheme adopted by the utility model is that：
A kind of reinforced parallel shield, including neck bush and arm set, arm set is one end occluded ellipse cylinder, in blind end
End face is formed with eccentric shaft neck bore, and integrally extension is formed with axial neck bush to the outer rim of journal hole, covers inner surface one in neck set and arm
Body sulfuric horizon scuff-resistant coating.
Moreover, neck bush height is less than the height of arm set.
The advantages of the utility model and good effect:
1st, reinforced parallel shield provided by the utility model uses integrally formed parallel shield, simple for process, structure
Rationally, it is convenient for disassembly and assembly, and crank arm and maneton are protected simultaneously, it repairs in time, and improves after ensureing crankshaft wear
The service life of bent axle.
2nd, reinforced parallel shield provided by the utility model is integrally integrally made by rubber mass, and is pasted in its inner surface
There is one layer of scuff-resistant coating, which can be used the anti-wear materials such as aramid fabric or glass fibre, improve the wearability of parallel shield,
Improve the service life of parallel shield.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the rearview of the utility model；
Fig. 4 is the side view of the utility model；
Fig. 5 is the sectional view of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
A kind of reinforced parallel shield, including neck bush 2 and arm set 1, arm set is one end occluded ellipse cylinder, is being closed
End end face is formed with eccentric shaft neck bore, and integrally extension is formed with axial neck bush to the outer rim of journal hole, and neck bush height is less than arm set
Height.
The utility model be by the integrally formed parallel shield of rubber mass, in order to improve the wearability of the shield,
One layer of scuff-resistant coating 3 of its inner surface integrated vulcanizing, the scuff-resistant coating is using materials such as aramid fabric or glass fibres.
During concrete application, the parallel shield directly set is covered on bent axle, is then rotated together with bent axle.
The utility model provides a kind of parallel shield, simple for process using integrally formed parallel shield, conjunction simple in structure
Reason, and protects crank arm and maneton simultaneously, ensures to repair after crankshaft wear timely, and improve bent axle uses the longevity
Life.
A kind of parallel shield provided by the utility model is integrally integrally made by rubber mass, and is pasted with one in its inner surface
Layer scuff-resistant coating, the scuff-resistant coating can be used the anti-wear materials such as aramid fabric or glass fibre, improve the wearability of parallel shield, improve
The service life of parallel shield.
Claims (2)
