Abstract
A bush assembly comprising a component having a bore, a bush fitted in the bore and having a flange that extends radially outwardly over a surface of the component surrounding the bore, and a seal assembly for sealing the interface between the flange and the surface of the component, wherein the seal assembly includes a seal member and a layer of sealant between the seal member and the interface between the flange and the surface of the component. Also a method for sealing a bush, a kit of parts for forming a bush assembly, and a clamping tool for forming a bush assembly.
Claims15
A bush assembly comprising a component having a bore, a bush fitted in the bore and having a flange that extends radially outwardly over a surface of the component surrounding the bore, and a seal assembly for sealing the interface between the flange and the surface of the component, wherein the seal assembly includes a seal member and a layer of sealant between the seal member and the interface between the flange and the surface of the component.
A kit of parts for forming a bush assembly, the kit of parts comprising a bush for fitting in a bore in a component, a seal member and a sealant material;
- wherein the bush has a flange that is adapted to extend radially outwardly over a surface of the component surrounding the bore when the bush is fitted in the bore;
- and wherein the sealant material is for providing a layer of sealant between the seal member and an interface between the flange and the surface of the component such that the layer of sealant and the seal member form a seal assembly for sealing the interface between the flange and the surface of the component.
A method for sealing a bush, the method comprising the steps of:
- providing a component having a bore with a bush fitted in the bore, the bush having a flange that extends radially outwardly over a surface of the component surrounding the bore;
- arranging a seal member with respect to the bush;
- and introducing a sealant material so as to provide a layer of the sealant material between the seal member and an interface between the flange and the surface of the component to form a seal assembly for sealing the interface between the flange and the surface of the component.
A clamping tool for applying a clamping force for sealing a bush installed in a bore in a component, the tool comprising a first part, a second part and a clamping mechanism;
- wherein the first part comprises a recess which is adapted to engage a seal;
- the second part is adapted to engage a surface of the component which opposes and faces away from a surface of the component on which the seal is provided;
- the clamping mechanism is operable to move the first part relative to the second part, thereby applying a clamping force to the seal;
- and wherein the clamping tool includes centring means for centring the clamping tool relative to the bush.
