The invention relates to an apparatus for the compensation of tolerances between components to be screwed to one another, comprising a hollow-cylindrical base element and a hollow-cylindrical compensation element which is in threaded engagement with the base element and which can be moved from a starting position into a compensation position by rotation relative to the base element. The apparatus is characterized in that a fixing means is provided by which the compensation element can be fixed in the compensation position relative to the base element.

The present disclosure relates to a tolerance compensation device for bridging a distance between two components to be connected to one another, comprising a base element and a compensating element which can be screwed into the base element, the base element forming at least one stop and the compensating element having at least one elastically deformable transport securing means which is designed in such a way that it must overcome the stop with temporary deformation in order to screw the compensating element into the base element.

According to the present invention, a blind fastening system for connecting members to one another comprises two parts; a structure containing a conical nut, matched to a threaded rod engaged to a lineal guide and a driven gear meshed to a driving gear having a tooling interface as the first part and; a separate structure containing anchor plates with springs and spring supports to act on and retain the conical nut of the first part. The blind fastening system also has a friction collar, a drive shaft, a retractable mechanism, a funnel tool guide, dowels and aligning & restricting guides.

The invention relates to a tolerance compensation apparatus comprising a base element; a compensation element that is in threaded engagement with the base element and that forms a passage extending in an axial direction for a screw element; a nut into which the screw element can be screwed; and a holding element having a first limb holding the base element, a second limb holding the nut, and a connection section connecting the first and second limbs, wherein the first and second limbs are spaced apart from one another while forming a reception gap for receiving a component.

A fastening assembly is provided which comprises a compensating element and an isolating member. The compensating element comprises a body having a receiving hole and a retaining flange provided at a first end of the body and having a retaining hole. The isolating member is made of metal and comprises a sleeve portion defining a channel. A fastening element inserted from a second end of the body of the compensating element can enter the channel and move in the channel in one or more lateral directions. The sleeve portion is inserted into the retaining hole and cooperates with the retaining hole to retain the isolating member in the compensating element. The fastening element fastens the compensating element to the second component via the sleeve portion, and the sleeve portion is configured to withstand an axial fastening force exerted by the fastening element on the retaining flange of the compensating element.

A fixing device includes an inner sleeve with a passage and a stop groove on the inside, an annular convex portion on the top and a positioning structure on the bottom, a fixing member having a head portion, a guide slope extending obliquely downward from the head portion and a coupling portion downwardly extending from the head portion and inserted into the passage of the inner sleeve, and an outer sleeve having a receiving space formed on the inside, a top surface formed on the top, a bevel groove formed on the top surface and extending obliquely inward corresponding to the opening of the receiving space and a limiting ring portion formed on the bottom and bent inward to cover the annular convex portion. This allows the fixing member to have a long vertical stroke and reduces the structural height of the fixing device.

A double-eccentric connecting device for connecting a fixing lug to a clevis and connecting system comprising at least one such connecting device is disclosed. The connecting device includes a main sleeve having a central section inserted into an orifice of the fixing lug and two end sections on either side of the central section, the centers of the external surfaces of the two end sections being offset from the center of the external surface of the central section, as well as two bushings, each of them inserted into an orifice passing through the clevis and mounted on one of the end sections, each of the bushings having an external surface the center of which is offset from the center of its internal surface, the connecting device thus including two eccentric elements, making it possible, through appropriate angular positioning, to compensate for an alignment error between the orifice passing through the fixing lug and the through-orifices of the clevis.
