Abstract
A pulling tool (1) of the type used on the end of a shaft (2) to remove a mechanical part (3) that is force-fitted or stuck to the shaft (2). The tool includes a threaded rod (20) and a body (5) to which legs (6) are hinged. A sleeve is designed to be mounted on the threaded rod (20) and to form a bearing member for a member (27) which inhibits rotation of the legs (6) during screwing of the threaded rod. Thus, the sleeve acts as a member for protecting the threaded rod (20) from the rotation-inhibiting member (27).
Claims12
A pulling tool for removing a mechanical part that is force-fitted or stuck on a shaft, said pulling tool comprising:
- a body portion;
- a threaded rod received in said body portion, said threaded rod having a first end defining a driving portion, and a second end for bearing on a face of the shaft;
- a plurality of legs pivotally connected to said body portion, each of said legs having a free end for bearing on a face of the mechanical part to be removed, wherein said threaded rod is capable of moving axially relative to said body and said legs;
- and
- a sleeve mounted on said threaded rod separately from said body portion, said sleeve having an outer bearing surface,
- wherein said sleeve defines a bearing member for a reaction member bearing on at least one leg and on the bearing surface of said sleeve to inhibit rotation of said legs during rotation of said threaded rod, and
- wherein said sleeve includes an outer peripheral surface which defines at least one groove.
A pulling tool for removing a mechanical part that is force-fitted or stuck on a shaft, said pulling tool comprising:
- a body portion;
- a threaded rod received in said body portion, said threaded rod having a first end defining a driving portion, and a second end for bearing on a face of the shaft;
- a plurality of leas pivotally connected to said body portion, each of said legs having a free end for bearing on a face of the mechanical part to be removed, wherein said threaded rod is capable of moving axially relative to said body and said legs;
- and
- a sleeve mounted on said threaded rod separately from said body portion, said sleeve having an outer bearing surface,
- wherein said sleeve defines a bearing member for a reaction member bearing on at least one leg and on the bearing surface of said sleeve to inhibit rotation of said legs during rotation of said threaded rod, and
- wherein said sleeve includes an outer peripheral surface which defines an annular groove.
A pulling tool for removing a mechanical part that is force-fitted or stuck on a shaft, said pulling tool comprising:
- a body portion;
- a threaded rod received in said body portion, said threaded rod having a first end defining a driving portion, and a second end for bearing on a face of the shaft;
- a plurality of legs pivotally connected to said body portion, each of said legs having a free end for bearing on a face of the mechanical part to be removed, wherein said threaded rod is capable of moving axially relative to said body and said legs;
- and
- a sleeve mounted on said threaded rod separately from said body portion, said sleeve having an outer bearing surface,
- wherein said sleeve defines a bearing member for a reaction member bearing on at least one leg and on the bearing surface of said sleeve to inhibit rotation of said legs during rotation of said threaded rod, and
- wherein a position of said sleeve on said threaded member is adjustable independently of a position of said body portion.
