Title:
軸方向弾性軸受を有するはすば歯車装置及びこれを装備する電動パワーステアリング
Document Type and Number:
Japanese Patent JP2011515627
Kind Code:
A
Abstract:
A helical bevel gear is proposed, in particular a worm gear, for an electrical auxiliary control, wherein said gear (G) has a pinion or a worm (1), which can be connected to a drive shaft of an electrical drive motor, and which is disposed in a gear housing, and is engaged with a helical wheel or worm wheel, wherein said pinion or said worm (1) is mounted radially and axially, wherein said gear (G) contains a bearing provided with balls (2) for the axial mounting of said pinion or said worm (1), which is secured in the axial direction (x) using at least one elastic element (5). The use of a special pivot bearing or pendulum bearing for a pivotable mounting of the pinion and/or the worm can even be disposed with by a helical bevel gear or worm gear (G) designed in this way. The axial mounting of the pinion or the worm can be implemented relatively simply and cost effectively, for example by a spring (5), the spring force thereof preferably being able to be adjusted using a set screw (6). Overall, a design of a low noise pinion or worm gear which is cost effective to produce and simple to handle in assembly thus results.
