Abstract
A system for the transmission of power formed by a block that has a channel, groove or canal of some length, one or more keys that come in contact with the groove, guide, or with the walls of the channel and with the key or keys holding a shaft or quill in eccentric holes in the keys. The system serves to eliminate or compensate for vibration caused by bent shafts or quills as well as the noise and wear that these can produce.
Claims18
A coupling apparatus for rotary power transmission and axial movement between a first elongated rotary member and a second rotary member substantially concentric with the first elongated rotary member, including
- a channel portion formed in an interior portion of the second rotary member and having at least one flat guide surface,
- at least one drive key positioned within the channel portion of the second rotary member and including another flat guide surface complementary to the one flat guide surface to allow linear sliding movement between the drive key and the channel portion along the flat guide surfaces and to prevent relative rotational movement between the drive key and the channel portion,
- the at least one drive key additionally including an opening for receiving the first elongated rotary member, and
- means for coupling the first elongated rotary member within the opening of the drive key to allow axial movement between the first elongated rotary member and the drive key and to prevent relative rotational movement between the first elongated rotary member and the drive key.
A coupling apparatus for rotary power transmission between a first rotary member and a second rotary member substantially concentric with the first rotary member, including
- a channel portion formed in an interior portion of the second rotary member and having at least one flat guide surface,
- at least one drive key positioned within the channel portion of the second rotary member and including another flat guide surface complementary to the one flat guide surface to allow linear sliding movement between the drive key and the channel portion along the flat guide surfaces and to prevent relative rotational movement between the drive key and the channel portion,
- the at least one drive key additionally including a noncentered opening for receiving the first rotary member, and
- means for coupling the first rotary member within the noncentered opening of the drive key to prevent relative rotational movement between the first elongated rotary member and the drive key and with the noncentered opening in the at least one drive key providing displacement of the drive key by centrifugal force during rotation to suppress vibration and noise.
