Abstract
The invention relates to a device for providing a friction joint by pressing a number of first elements against a second element by means of a pressure medium acting on said first elements. In order to obtain an improved ability of transmitting a torque and an improved stability regarding radial load, said first elements are so arranged that they encircle or are encircled by said second element and are acted upon by a number of mutually independent portions of the pressure medium, each portion acting on its own element.
Claims9
Means providing a friction joint between a pair of members having confronting surfaces comprising a plurality of spaced pockets in the confronting surface of one of said members arranged in an annular pattern, an element mounted in each of said pockets, means for independently pressurizing by a fluid pressure medium each of said pockets to thereby actuate the said elements into pressure applying relation with the surface of the other member which they confront and means for selectively relieving independently the pressure in each pocket, said pockets defined by wall portions including radial walls separating the pockets circumferentially disposed closely adjacent the confronting surface of said other member whereby forces are transmitted via said elements and said walls defining said pockets, said elements bring rigid members and seal means made of a resilient elastic material surrounding the periphery of each element and contacting said elements and the walls of said pocket.
Means providing a friction joint between a pair of members having first and second annular confronting surfaces spaced apart to define an annular space comprising a flexible resilient sleeve member in the annular space between the confronting surfaces of said members, said sleeve member sealingly connected to one of said members in a predetermined pattern defining a plurality of independent non-secured sleeve portions, each said non-secured sleeve portion and surface of said one member defining a pocket, said plurality of pockets being arranged in an annular pattern, means for independently pressurizing by a fluid pressure medium each of said pockets so that the non-secured sleeve portions deflect into pressure applying relation with the confronting surface of the other member which the sleeve confronts and means for selectively relieving independently the pressure in each pocket.
