Abstract

A high-speed fastening system includes a conventional yoke coupled to a likewise conventional shaft provided with specific fastening elements, via a vertically movable outer casing and a central body into which the shaft is inserted so as to secure the yoke to the aforementioned shaft. The auxiliary components, in addition to those already mentioned, include a catch fitted in the arch of the yoke, an intermediate sleeve inserted into the inner part of the central body, an inner spring situated inside the sleeve, and an outer spring whose ends rest in the arched part of the yoke and in the lower part of the outer casing. The shaft is fitted or dismantled from the interior of the yoke body by conventional ball bearings in combination with an annular zone situated in the insertion zone of the aforementioned shaft. The system, by slight pressure of the shaft downwards towards the yoke body, enables the bearings to be interlocked by insertion with the insertion zone, whereas the shaft can be freed from the insertion zone by an opposite movement, by the downward pressure of the outer casing.

Claims

1. A high speed fastening system comprising

a shaft,

a yoke having arms each provided with a bearing housing for corresponding bearings and having an arch reinforced by ribs,

said shaft being coupled to said yoke by a cylindrical outer casing containing a central body having a lower part extending into said arch of said yoke, said central body and said cylindrical outer casing containing corresponding parts for fastening, pressure and alignment of said central body and said cylindrical outer casing, said parts including an exterior surface of said central body cooperating with a groove in said cylindrical outer casing so that said central body can fit into said cylindrical outer casing only in a single orientation between said central body and said cylindrical outer casing.

2. The high speed fastening system claimed in claim 1, wherein the coupling between said shaft and said yoke is performed by bores in a cylindrical surface of said central body which contain ball bearings, an upper one of said ball bearings being inserted in a grooved zone, whereas a second one of said ball bearings is in an upper part of an intermediate sleeve in combination with a catch fitted in an inner part of the lower part of said central body and said intermediate sleeve being subjected to pressure by a intermediate spring, an inner spring being disposed inside said intermediate spring and in said catch.

3. The high speed fastening system as claimed in claim 2, wherein a pressure device located between said cylindrical outer casing and an arched zone of said yoke includes an outer spring, one end of which bears on an upper part of said yoke whereas an opposite end bears on a supporting zone at s bottom part of said cylindrical outer casing.
