Description
Claims (3)
- 回転運動を直線運動に変換するための伝動装置であって、
ねじ山付スピンドル(1)が設けられており、
少なくとも1つの支持軸受(11)が設けられており、
軸受ケーシング(6)が設けられており、
ねじ山付きスピンドル(1)の外径よりも大きな内径を有する、ねじ山付スピンドル(1)に対して軸平行に支承されたナット(2)が設けられており、
ナット(2)の軸線(10)とねじ山付スピンドル(1)の軸線(9)とが、互いに偏心率(e)を有しており、
ナット(2)が、少なくとも1つのねじ条を備えており、
ナット(2)のねじ条が、リードを有しておらず、かつねじ山付スピンドル(1)のねじの谷(8)に少なくとも部分的に係合するようになっている形式のものにおいて、
ねじ山付きスピンドル(1)の回転運動をナット(2)の直線運動に変換するために、ナット(2)のねじ山のフランク角(α)が、実質的にねじ山付スピンドル(1)のねじ山のフランク角(β)に相当しており、ねじ山フランク(12,13)が、少なくとも軸方向力を伝達する側で、実質的に真っ直ぐに延びており、
ナット(2)が、溝と呼ばれる複数のねじ条(14)を備え、
ナット(2)の連続する2つの溝(14)の間の間隔が、ねじ山付スピンドル(1)のねじ山リード(p 1 )に相当しており、
ナット(2)の軸方向の支承を行う滑り軸受が、ナット(2)と、該ナット(2)を介して前記ねじ山付きスピンドル(1)の軸方向力が直接伝達されるケーシング(17)との間の三日月形の接触領域(20)によって形成されていることを特徴とする、回転運動を直線運動に変換するための伝動装置。 - 軸線(9,10)が、空間内で互いに平行に延びている、請求項1記載の伝動装置。
- ナット(2)の支承が、前記支持軸受(11)に含まれる少なくとも1つのラジアルニードル軸受(15)によって行われるようになっている、請求項1又は2記載の伝動装置。
