Description
Technical field
A kind of auto parts and components are the utility model is related to, more particularly to a kind of camshaft of car engine FE Tiler.
Background technology
Camshaft is a part in piston engine.Its effect is to control unlatching and the closed action of valve.Though
So the rotating speed of camshaft is the half of bent axle in four-stroke engine（In the rotating speed and bent axle of two stroke engine convexity wheel shaft
It is identical）, but generally its rotating speed is still very high, and needs to bear very big moment of torsion, thus in designing to camshaft strong
Requirement in terms of degree and support is very high, and its material is usually superior alloy steel or steel alloy.Because valve motion rule is related to
The power and service performance of one engine, thus camshaft design in the design process of engine in occupation of highly important
Status.And camshaft, during high-speed rotation, its surface is easily worn.And during cam axle, it is
The abrasion of camshaft is reduced, FE Tiler be housed on camshaft, form oil film by FE Tiler rubs to reduce.Fluid is in lubrication
During, usually flowed, and many times, the flow handle of fluid is irregular, so that the oil film that fluid is formed
Compare chaotic, do not reach requirement.
Utility model content
The purpose of this utility model, which is to provide, a kind of can allow fluid automobile engine of flow rule in FE Tiler convex
Take turns axle bush covers.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of camshaft of car engine FE Tiler, including lid and the mounting blocks for being arranged on lid both sides, the installation
Mounting hole is provided with block, deep-slotted chip breaker is offered on the lid, oil groove is provided with the deep-slotted chip breaker, is set in the oil groove
There is oilhole, the lid is provided with boss away from the side of deep-slotted chip breaker, and the oilhole is extended on boss, is set on the boss
There is oil inlet passage, non-return structure is provided with the oil inlet passage.
By using above-mentioned technical proposal, oil inlet passage by non-return structure by fluid one-way flow, so as to which fluid will not
Backflow, the fluid of inside is allowed to flow comparison rule, so as to not allow fluid to influence each other.Deep-slotted chip breaker can install bearing shell, oilhole
Pump oil lubrication is carried out for bearing shell.
The utility model is further arranged to：The oil inlet passage includes interconnected first passage and second channel,
The first passage is extended on boss, and the non-return structure is arranged in second channel.
By using above-mentioned technical proposal, fluid is entered by second channel, while will not be flowed back from second channel, is entered
To after first passage, the hole on by boss, which is flowed into oil groove, to be lubricated.
The utility model is further arranged to：The non-return structure includes setting shrinkage cavity and installation on a second pass
Hoodle in second channel, the hoodle coordinate with shrinkage cavity, and the shrinkage cavity is placed in one end that second channel deviates from first passage.
By using above-mentioned technical proposal, hoodle can block to second channel, meanwhile, the setting of shrinkage cavity can allow
Hoodle carries out individual event closure, and then fluid can be allowed to enter.
The utility model is further arranged to：First passage position is provided with limiting section in the second channel.
By using above-mentioned technical proposal, limiting section can limit the sliding position of hoodle.
The utility model is further arranged to：Spring is provided with the second channel, the spring one end supports with hoodle
Touch, the other end contradicts with first passage inwall.
By using above-mentioned technical proposal, it can allow hoodle that second channel is in into sealed condition all the time using spring, and
In oil-feed, it is necessary to which the power of certain pump oil can will be due to being pumped into inside.
The utility model is further arranged to：The boss is provided with the projection for extending lid, is set on the projection
Fluted, the second channel is opened on groove.
By using above-mentioned technical proposal, the setting of groove makes the direction ratio of second channel oil-feed more various, facilitates fluid
Into.
In summary, the utility model has the advantages that：The setting of non-return structure, can allow fluid be merely able to from
Oil inlet passage enters, and without flowing back, so as to which fluid forms certain flow direction, and then oil film is relatively more steady during formation
It is fixed, and then allow the friction of bearing shell and camshaft to reduce.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of camshaft of car engine FE Tiler, as shown in Figure 1 and Figure 4, including the lid 1 that is set in arcuation and with lid
The mounting blocks 2 that body 1 is wholely set, are provided with mounting hole 21 on mounting blocks 2, by mounting hole 21 it can be fixed.
Bearing shell is placed on lid 1, is coordinated by two FE Tilers, bolt will be worn in mounting hole 21, allow it to fix, centre is formed for convex
The through hole 3 that wheel shaft passes through, now, under the high-speed rotation of camshaft, bearing shell surface attachment has one layer of oil film, and then forms one layer
Lubricating layer, the resistance that camshaft is subject to when rotating can be reduced, and then make the control ratio of camshaft more accurate.
As shown in Fig. 2 the inside of lid 1 sets deep-slotted chip breaker 11, deep-slotted chip breaker 11 is used to install bearing shell, and bearing shell is carried out with camshaft
Contact.Gap between bearing shell and camshaft influences whether the amount of the fluid on camshaft surface, therefore, in order to allow what fluid was stablized
It can be input on bearing shell, the pressure of pump oil can be influenceed by adjusting the gap between bearing shell and camshaft.
As shown in Figures 2 and 3, oil groove 12 is offered on the inwall of lid 1, oilhole 4 is provided with oil groove 12, passes through oil
