Description
Technical field
A kind of transmission component of the utility model relates in particular to a kind of low friction carrier bar chain.
Background technique
Chain is widely used in the car engine timing drive system as a kind of transmission component.But existing chain is applied in and has certain deficiency in this system: correct-timing drive system is provided with guard rail guiding chain, chain panel edges and the sliding friction between the guard rail guide surface of chain are serious, increase the power loss of correct-timing drive system, thereby affect Fuel Economy.
Chinese patent notice of authorization number: CN 201306412, notice of authorization day: on September 9th, 2009, a kind of engine chain is disclosed, comprise inner plate, sleeve, bearing pin and outer plate, inner plate and sleeve interference fit, bearing pin is through in sleeve, and head is exposed at bearing pin two ends from sleeve, outer plate connects the axle head of appearing of two adjacent bearing pins, and the outer wide size of inner plate is poor less than sleeve height dimension and place, outer, 2 times of sleeve two ends knuckle.The utility model guarantees that the Interference contact area of inner plate and sleeve assembly and connection equals the surface area in inner plate hole, thereby in the situation that inner plate hole and sleeve outer diameter and sleeve outer diameter assembling magnitude of interference are constant, improved the link fastness of inner link sleeve with inner plate, avoided the internal segment of chain under high speed variable load transmission to shift to an earlier date failure damage, satisfy motor to the area that chain weares and teares mutually under high-speed drive, greatly extended the working life of chain.Its deficiency is: between chain and guard rail, sliding friction increases the correct-timing drive system power loss.
The model utility content
The utility model be in the correct-timing drive system that overcomes prior art between chain and guard rail sliding friction increase the deficiency of correct-timing drive system power loss, a kind of a kind of low friction carrier bar chain that can reduce friction energy loss between chain and guard rail is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of low friction carrier bar chain, comprise inner plate and outer plate, the vertical setting-in sleeve in inner plate two ends, the outer plate two ends are provided with coupling shaft, inside and outside carrier bar passes sleeve by coupling shaft and alternately connects, each outer plate is positioned at the coupling shaft two ends extension protrusion outer plate surface of same end, this side coupling shaft two ends socket roller, and the diameter of described roller is greater than the outer plate width.When chain slided on guard rail, roller replaced original chain panel edges to contact with guard rail, and the change sliding friction is rolling friction, thereby reduced the friction energy loss between chain and guard rail.
As preferably, after the diameter of described roller is connected with inner plate less than a pair of outer plate 1/2nd of overall length.Crossing large diameter roller can be when chain be crooked and the adjacent rollers touching, and two roller linear velocity opposite directions of touch points cause roller stuck, affects chain transmission.Therefore the diameter of roller is connected 1/2nd of rear overall length with inner plate less than a pair of outer plate, and in correct-timing drive system, chain may crooked degree to adapt to.
As preferably, the roller side is provided with some lightening holes along connecting in axle collar week.Alleviate roller weight, reduce the contact of roller and guard rail guide surface, help reduce the friction.And lightening hole is communicated with roller bi-side, reduces to roll and covers the outer plate surface area, makes lubricant oil more easily flow into the surface of contact of roller and outer plate, increases this surface of contact lubrication effect, reduces the sliding friction between roller side and outer plate surface.
As preferably, lightening hole is shaped as the fan ring, and described fan ring and roller side are concentric.The lightening hole of fan annular can fully alleviate roller weight, and each fan ring is all concentric with roller, and the external diameter of fan ring is the radial strength that circular arc guarantees roller, guarantees mechanism's intensity of roller.
As preferably, also be provided with axle sleeve between roller and coupling shaft, described axle sleeve comprises the cylinder-shaped sleeve at socket coupling shaft two ends and the circular limiting board in the adapter sleeve outside, roller housing is connected on sleeve pipe.Chain sliding speed on guard rail of facing in drive system is very fast owing to being applied in.The frictional heating of roller and coupling shaft is serious, and coupling shaft also will play the important function that connects inside and outside carrier bar simultaneously, and long-time frictional heating can badly influence chain working life.Axle sleeve plays the effect of protection coupling shaft, extends the utility model working life.
As preferably, be provided with roller bearing between sleeve pipe and roller.It is large that roller bearing bears load carrying capacity, is applicable to High Rotation Speed mechanism, can effectively reduce between roller and sleeve pipe and rub.
Therefore, the utlity model has following beneficial effect: (1) roller reduces the friction energy loss between chain and guard rail, increases engine fuel efficient; (2) improve the lubricant oil its usage economy; (3) structural strength is high, long service life.

Fig. 2 is partial sectional view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment: as shown in Figure 1 and Figure 2, a kind of low friction carrier bar chain of the present utility model comprises inner plate 1 and outer plate 2, the inner plate 1 vertical setting-in sleeve 11 in two ends, outer plate 2 two ends are provided with coupling shaft 3, and inside and outside carrier bar passes sleeve 11 by coupling shaft 3 and alternately connects.Each outer plate 2 is positioned at coupling shaft 3 two ends extension protrusion outer plate 2 outer surfaces of same end, and is socketed the installation axle sleeve at the two ends of coupling shaft 3 by interference fit.Described axle sleeve comprises the sleeve pipe 61 that is socketed in coupling shaft 3 two ends and the circular limiting board 62 of adapter sleeve 61 ends.Be socketed with roller bearing 7 on sleeve pipe 61, the outer roller 4 that is socketed with of roller bearing 7.Limiting board 62 is positioned at roller 4 outsides.The diameter of described roller 4 greater than outer plate 2 width and less than a pair of outer plate 2 is connected with inner plate connect after overall length 1/2nd.Roller 4 replaces outer plate 2 edges contact with guard rail, and cross large diameter roller 4 can be when chain be crooked and adjacent rollers 4 touch, and two roller 4 linear velocity opposite directions of touch points cause roller 4 stuck, affect chain transmission.Therefore the diameter of roller 4 less than a pair of outer plate 2 is connected with inner plate connect after overall length 1/2nd, in correct-timing drive system, chain may crooked degree to adapt to.Axle sleeve plays the effect of protection coupling shaft 3, prevents the 3 serious frictions heatings of roller 4 and coupling shaft, extends the utility model working life.
Roller 4 sides are along coupling shaft 3 a ring annular lightening hole 5 of fan Thursday.The annular lightening hole 5 of described fan and roller 4 with one heart and central angle be 60 °.Lightening hole 5 is positioned at limiting board 62 near the inner arc edge in roller 4 centers of circle, side.The lightening hole 5 of fan annular can fully alleviate roller 4 weight, and each fan ring is all concentric with roller 4, and the external diameter of fan ring is the radial strength that circular arc guarantees roller 4, guarantees mechanism's intensity of roller 4.Simultaneously, lightening hole 5 is communicated with roller 4 bi-side, reduces and rolls the zone of covering outer plate 2 surfaces and limiting board 62 inner side surfaces, makes lubricant oil more easily flow into the surface of contact of roller 4 and outer plate 2, increase this surface of contact lubrication effect, reduce the sliding friction between roller 4 sides and outer plate 2 surfaces.
