Description
Technical field
Present invention relates in general to tension device, more specifically, relate to the installation shaft assembly that is used for tension device.
Background technique
Belt stretcher known in the state of the art is used for automobile and is used for to belt or chain imposed load, keeping the tensioning of aequum on belt drive unit, thereby drives the various parts that are attached to belt system.In addition, belt stretcher is used for asynchronous belt drive system, to prevent belt slippage and power transmission loss.Tension device is generally used in the assistant drive system and Timing Belt or timing chain system of automobile.
Typically, belt stretcher comprises tension arms, and this tension arms cooperates with idle pulley on being installed in ball bearing assembly.Tension arms is installed on the pivot pivotally.Helical spring twines around pivot coaxially, is used for this tension arms of pre-tensioning, thereby makes idle pulley power can be applied on the belt.In this way, helical spring power is applied to load on the belt, simultaneously idle pulley deflection and tighten belt or the length of chain lax.
In certain was used, the space size that can be used for installation tensioner on the motor was limited.The very valuable Timing Belt in space is all the more so in using on motor.In these are used, use double eccentric gear type tension device usually.First eccentric has and the tension arms identical functions.Second eccentric or installation shaft are regulated tension device during installation in advance required load is applied on the belt.
When tension device was installed on the motor, the position of tension device need be adjusted to consistent with the mounting point of stipulating.Tension device is fixedly secured to Engine Surface behind directed and location correctly.One adjusting or installation shaft assembly are used to locate tension device, and keep suitable belt tension.The method that the belt stretcher and being used for that is used for motor vehicle is installed to belt stretcher in motor comprises: U.S. Patent No. 5,919,107,6,149,542,6,364,795,6,375,558 and 6,464,604.
Now, by using for example known methods such as injection molding sintering metal, die casting aluminium and die case zinc, installation shaft can be constructed as single type and be produced, although majority is a two-piece construction.Although these parts be it seems enough simple,, for example the die casting of installation shaft and extrusion shapes have very large length diameter ratio, so be difficult to make, need expensive processing, and have extremely expensive processing cost and the maintenance cost that is associated with it.
Alternatively, installation shaft can be made by adopting the two-piece type stamped steel to design.Mounting plate and cylindrical guide pile tube meet (stake) and arrive together to form installation shaft.With upper mounting plate in conjunction with or stake to receive down the needed stake of leading pipe bonding tool also be quite expensive, and need the cost of complicated assembling, also need often maintenance to keep the integrity that connects.
And the installation shaft that connects of stake may be because the variation of part dimension and stake connect the variation that operation causes has and a plurality of the inconsistencies that joint is relevant.These variations may make required power difference when being installed to tension device on the motor, cause tension device to locate irrelevantly or damage.
Although process and principle that stake connects seem fairly simple, but it also needs material to be joined to be beaten (impact) and just enough distortion, and indeformable excessively so that parts are kept together, and keep required clamping force and parts around can not making are cracked or block.The clamping force that stake connects can change on a large scale along with the minor variations of following factors: material behavior (Kohlenstoffgehalt, hardness, granular structure, flow characteristic); The tolerance of each parts adds up in connecting, and this has determined final impact force; Compress into the degree of depth and material flow characteristic, and the other factors of stake bonding tool state, punching press state and deflection for example; Initial punching press configuration; And a large amount of other factors.
If the stake in pivot of eccentric installation shaft connects too fiercely, stake connects mould or the punch assembly too much material that will be shifted, and eccentric shaft will be fused together with pivot.Now, eccentric or adhere to when rotating or do not rotate when reversing with the power of suitable size finally can not freely rotate.In the time of on being installed to motor, operator or installation machinery (being automatic torque wrench) will apply power to eccentric installation shaft by setting tool, tension device is pushed away or turns in the belt attempting, and with the nominal belt label alignment that identifies on tensioner arm pointer and the stamped steel substrate.If the setting-up eccentricity device does not rotate (promptly being completely fixed) in pivot because the stake relay is too high, perhaps fitting operation will stop when torque limit surpasses, perhaps if there is not this kind limit, and the plastic deformation of mounting plate possibility, perhaps badly, break away from from vertical tubular portion.If tension device partly retrains (promptly partly blocking) in pivot, install operation process will above or do not reach nominal belt mark, its reason is, be applied to most of torque on the setting-up eccentricity device and will be used to overcome irregular friction between eccentric and the pivot separating surface, rather than make tension device enter into belt.
If eccentric installation shaft stake connects too softly, stake connects mould or the punch assembly very few material that will be shifted, and eccentric installation shaft will be free to slide with respect to pivot, and allow tension device during transporting, operation period or as installed drop during to the motor.Tension device between installation period " blast " may make engine line shut down; because each part must be located and identify; to guarantee that it can not be absorbed in the correct-timing drive system,, will cause belt jumping tooth or chain to be skipped if a part is taken in by the timing drive unit.
Thereby, still being desirable to provide a kind of tensioning installation shaft, its low cost of manufacture also provides reliable and effective device that tension device is installed and navigated on the internal-combustion engine.
