Abstract
For an assembly of two bodies wherein one of the bodies has a part-ball portion and the other has a part-ball formed hollow seat of complementary surface, a slot is provided in the body with the hollow portion and the ball formed portion of the other body is mounted into the hollow portion, while a spring washer presses the bodies together when a snap ring having an extension engaging into the slot and being kept in a ring groove is inserted into the hollow portion. The body with the ball formed portion has retaining faces which are engaged by the washer and the washer also has an extension to enter into the slot, whereby the assembly assures, that one of the bodies can pivot relatively to the other body, but that the bodies are prevented from rotational movements relatively to each other.
Claims9
An assembly of two bodies, including:
- a first body, a second body, a span ring and a snap ring;
- wherein said first body has a hollow end portion forming in said endportion a seat with a seat face of a radius around a common centre whereby the said seat obtains the form of substantially a hollow half ball,
- wherein said second body has an end portion in the form of substantially a half ball with a radius corresponding to said radius and around said common centre,
- whereby said end portion of said second body is swingably borne on said seat of the said first body,
- wherein said second body has two parallel face portions on a narrowed portion inwards of said half-ball formed end portion,
- wherein said second body has between said half-ball formed end portion and said parallel face portions medial partial ends with shoulders substantially normal to said parallel face portions, wherein said first body has an annular ring groove extending radially from inside into said end portion of said first body,
- wherein said first body has at least one slot extending radially through said end portion of said first body,
- wherein an axial span-ring is inserted into said hollow end portion of said first body,
- wherein said span-ring is bowed under force towards said shoulders,
- wherein said span-ring has at least one radially extending finger,
- wherein said finger is inserted into said slot,
- wherein said span-ring has a radial opening defined by two parallel inner faces,
- wherein said parallel inner faces are facing said parallel face portions of said second body,
- wherein a snap ring is inserted under thrust against said span-ring into said annullar ring groove in said first body and wherein said span-ring is prevented from rotation relatively to said first body to said finger in said slot and rotation of said second body relatively to said span-ring is prevented by said parallel faces and the said bodies are kept together in said seat by thrust of said span ring onto said shoulders of said second body, while the ability of relative pivot motion between said bodies remains maintained.

An assembly of two bodies, including a first body, a second body, a spring ring and a snap ring,
- wherein said first body is a piston reciprocating in a radial piston machine and has a hollow upper end portion forming in said endportion a seat with a seat face of a radius around a common centre whereby the said seat obtains the form of substantially a hollow half ball,
- wherein said second body is a piston shoe pivotably connected to said piston and having an outer face to be guided along an actuator face for transferation of a stroke from said actuator face to said piston;
- wherein said second body has an end portion in the form of substantially a half ball with a radius corresponding to said radius and around said common centre,
- whereby said end portion of said second body is swingably borne on said seat of the said first body,
- wherein said second body has two parallel face portions on a norrowed portion inwards of said half-ball formed end portion,
- wherein said second body has between said half-ball formed end portion and said parallel face portions medial partial ends with shoulders substantially normal to said parallel face portions,
- wherein said first body has an annular ring groove extending radially from inside into said end portion of said first body,
- wherein said first body has at least one slot extending radially through said end portion of said first body,
- wherein an axial span-ring is inserted into said hollow end portion of said first body,
- wherein said span-ring is bowed under force towards said shoulders,
- wherein said span-ring has at least one radially extending finger,
- wherein said finger is inserted into said slot,
- wherein said span-ring has a radial opening defined by two parallel ring faces,
- wherein said parallel ring faces are facing said parallel faces of said second body,
- wherein a snap ring is inserted under thrust against said span-ring into said annular ring groove in said first body and wherein said span-ring is prevented from rotation relatively to said first body to said finger in said slot and rotation of said second body relatively to said span-ring is prevented by said parallel faces and the said bodies are kept together in said seat by thrust of said span-ring onto said shoulders of said second body, while the ability of relative pivot motion between said bodies remains maintained.
