Summary of the invention
Therefore task of the present invention is, realizes the vibration bridge according to classification, and this vibration bridge is not only optimized and carries out very large improvement with respect to known so far vibration bridge about accessible service life but also about noise minimization.
The feature that this task indicates by claim 1 is solved.
Solution according to the present invention realizes such formation connector in simple mode, the slipping property that this connector can be made and have especially with minimum manufacturing tolerance, all the other regions that meanwhile vibrate bridge are optimized about elasticity and service life.The formation of two-piece type be also conducive to from shaping jig can release property because the reduced complexity of unitary part.
In order to coordinate mutually with the load occurring on each self-excited oscillation bridge region as far as possible best, be of the present inventionly preferred embodiment designed to, connector is made by the raw material different from vibrating body.Two unitary part, namely the remainder of connector and vibrating body preferably unremovably interconnects after the combination by material deformation, and particularly they are welded to each other.
If connector and/or vibrating body have for connecting the securing member of these two members, for supporting reliably and simply assembling, be favourable so.
Favourable embodiment of the present invention is designed in addition, and connector is made by polyformaldehyde (POM), and in other words, the remainder of vibrating body and vibration bridge is made by polyamide (PA) except connector.POM is for example famous with particularly preferred slipping property, and this slipping property is favourable especially in the region of connector, in this region, appear at crank-type eccentric wheel type in other words part and vibrate accordingly the continuous relative motion between the leader of bridge side.In addition raw material POM is famous with very little water imbibition, realizes thus especially little manufacturing tolerance, and it further causes (as illustrated) noise to weaken above.Not generating material deformation in the region of connector, so that do not have basic importance about load variations elastic characteristic and endurance life characteristic.Coupling part or hinge portion that in contrast, described characteristic is contiguous on it in other words for shaker arm have the highest importance, raw material polyamide (PA) is particularly suitable for these members like this, because raw material polyamide has particularly preferred elasticity and extra high load variations tolerance.
Vibrating body, at least one shaker arm and at least one hinged member are advantageously integrally implemented and can be there is no thus further installation step ground and manufacture especially simply.
The vibration bridge according to the present invention of this form is particularly suitable for being applied in electric razors, and wherein, work package is at least one shearing elements of cutting system.Be just in the region of electric mini-plant in low manufacturing cost situation for service life and little noise producing proposing high requirement.
