Abstract
A device for locking in a removable way a mechanical member with a taper bore onto a shaft having a cylindrical section. A first bush is provided that has internal and external surfaces. A second bush is provided that is suitable to be inserted into the first one. The second bush has an external conical surface and a cylindrical internal surface. The relative axial position of the bushes are varied to engage and disengage the mutual coupling between the bushes and the coupling of the device with a shaft or with the mechanical member.
Claims18
A device for locking in a removable way a mechanical member having aa taper bore onto a shaft having a cylindrical section, of the type comprising:
- at least one first bush having a conical external surface and one or more grub-screws or bolts, each engageable for fixing said first bush to the mechanical member, said first bush having a conical internal surface;
- at least one second bush having a cylindrical internal surface and a conical external surface to bear against the conical internal surface of said first bush, said second bush being of such shape and size as to be inserted at least partially into said first bush;
- means for varying the relative axial position of the bushes;
- and said first bush consists of solid bush and said second bush consists of a bush having at least a split portion.
A device according to any of the preceding claim, characterised by said means for varying the relative axial position of said bushes comprising a plurality of bolts inserted in through-holes located on the annular flange of the said second bush and engaged in corresponding tapped holes arranged in the body of said first bush.
