Abstract
A multi-head, rack and pinion driven pulley puller including a rack and pinion drive assembly. The drive assembly includes a body member, a rack shaft, and a pinion gear, enclosed in the body member in one embodiment. The drive assembly further has a head that is adapted to receive a variety of puller assemblies, including a pivoting jaw puller assembly and a forked plate puller assembly.
Claims17
A rack and pinion driven pulley puller, said rack and pinion driven pulley puller comprising:
- a rack and pinion drive assembly having a body, a rack shaft adapted to cooperate with said body, a pinion gear in geared cooperation with said rack shaft, and a head;
- a drive port adapted for providing a rotational force to said pinion gear;
- and
- a pulley puller assembly adapted to be secured to said head of said rack and pinion drive assembly, wherein said pulley puller assembly includes a base adapted to be removably secured to said body and at least a pair of jaw members pivotally secured to said base and a shaft extension releasably received by an axial bore disposed in an upper end of said rack shaft.
A rack and pinion driven pulley puller, said rack and pinion driven pulley puller comprising:
- a rack and pinion drive assembly having a body, a rack shaft adapted to cooperate with said body, a pinion gear in geared cooperation with said rack shaft, and a head;
- a drive port adapted for providing a rotational force to said pinion gear;
- and
- a pulley puller assembly adapted to be releasably secured to said head of said rack and pinion drive assembly, wherein said rack and pinion driven pulley puller defines a multi-head rack and pinion driven pulley puller adapted to receive a pulley puller assembly selected from a group consisting of a pivoting jaw puller assembly and a forked plate puller assembly.
A rack and pinion driven pulley puller, said rack and pinion driven pulley puller comprising:
- a rack and pinion drive assembly having a body, a rack shaft adapted to cooperate with said body, a pinion gear in geared cooperation with said rack shaft, and a head;
- a drive port adapted for providing a rotational force to said pinion gear;
- and
- a pulley puller assembly adapted to be releasably secured to said head of said rack and pinion drive assembly wherein said pulley puller assembly includes a first forked plate member adapted to be releasably secured to said head of said rack and pinion drive assembly and a second forked plate member adapted to be secured to an upper end of said rack shaft such that actuation of said pinion gear biases said second forked plate member away from said first forked plate member.
