Description
本発明によるねじ伝動装置では、冒頭に述べた形式のねじ伝動装置において、請求項1の特徴部記載のように、すなわちねじ山は、変化するピッチを有しているように構成されている。
図1に示された本発明によるねじ伝動装置1は、ねじ山3を備えたスピンドル2と、ねじ山3に係合する対応部材4とを有している。この対応部材4はそれ自体ナットの機能を有しており、対応部材4はスピンドル2の回転駆動時に軸方向において移動させられる。
Claims (10)
- ねじ伝動装置であって、ねじ山(3)と、該ねじ山(3)に係合する対応部材(4)とが設けられていて、ねじ山(3)は対応部材(4)に対して回転可能であり、その結果対応部材(4)に対するねじ山(3)の回転運動によって、対応部材(4)はねじ山(3)に対して移動させられる形式のものにおいて、
ねじ山(3)は、変化するピッチを有し、
ねじ伝動装置(1)は、ねじ山(3)に対する対応部材(4)の移動時に変形するばねエレメント(17)を有しており、ねじ山(3)のピッチは、ばねエレメント(17)のばね力が該ばねエレメント(17)の変形によって小さくなる場合に、大きくなり、
ねじ山(3)の螺条(5)は始端部及び終端部に半径方向区分(29,30)を有し、半径方向区分(29,30)では、スピンドル(2)に対してモーメントが加えられることなしに対応部材(4)が軸方向に移動することが阻止されることを特徴とするねじ伝動装置。 - 対応部材(4)は、ねじ山(3)のねじ山側面(9)に沿って転動する転動体(8)を有している、請求項1記載のねじ伝動装置。
- ねじ山(3)は多条である、請求項1又は2記載のねじ伝動装置。
- 対応部材(4)は各螺条(5)のためにそれぞれ1つの転動体(8)を有している、請求項3記載のねじ伝動装置。
- ねじ山(3)は部分的にピッチを有していない、請求項4記載のねじ伝動装置。
- ねじ伝動装置(1)は1つの構成グループを形成している、請求項1から5までのいずれか1項記載のねじ伝動装置。
- ねじ伝動装置(1)は駆動モータ(13)を有している、請求項1から6までのいずれか1項記載のねじ伝動装置。
- ねじ伝動装置(1)は、ねじ山(3)を対応部材(4)と共に固定するブレーキ(32)を有している、請求項1から7までのいずれか1項記載のねじ伝動装置。
- 前記ばねエレメント(17)は、一方向(作業行程)におけるねじ山(3)に対する対応部材(4)の移動時に弛緩され、かつ駆動モータ(13)に加えて付加的にエネルギを放出し、かつばねエレメント(17)は、逆方向(戻り行程)におけるねじ山(3)に対する対応部材(4)の移動時に、駆動モータ(13)によってねじ伝動装置(1)を介して、外的負荷が戻り行程の方向でねじ山(3)又は対応部材(4)に対して作用する場合には、外的負荷によって助成されて緊張させられる、請求項1記載のねじ伝動装置。
- ねじ伝動装置(1)は駆動モータ(13)を有していて、ねじ伝動装置(1)は可変のダンパとして使用される、請求項1記載のねじ伝動装置。
