<p>A mechanism for converting rotating motion to rotating and reciprocating motion and/or for converting rotating and reciprocating motion to rotating motion. The mechanism includes a housing or support, a first member rotatable relative to the housing or support about a first axis and reciprocable along the first axis relative to the housing or support, and a second member rotatable relative to the housing or support about a second axis that is spaced from the first axis. The second member is operatively coupled to the first member such that rotation of one of the members causes rotation of the other of the members. The first member has a groove or channel and surfaces of the groove or channel provide two generally opposed cam surfaces. The second member has a projection and sides of the projection provide two generally opposed guide surfaces configured to be in rolling contact with the cam surfaces. The groove or channel has gear teeth forming a first gear and the projection on the second member has gear teeth forming a second gear configured to engage the first gear. The cam surfaces and the guide surfaces are configured to cause the first member to rotate upon movement of the first member along the first axis and/or to cause the first member to move along the first axis upon rotation of the first member.</p> |
