Abstract
A fishing reel employs a driving mechanism having a cooperative pinion gear and a face gear. The face gear has a tooth form with a cross-section wherein the cross-section of the inner pitch portion is less than the cross-section of an outer pitch portion. The pinion gear effectively engages the inner pitch portion less than an outer pitch portion to provide a more uniform distribution of torque and to improve the wearing rate of the gear mechanism.
Claims9
A fishing reel comprising:
- a spool;
- a rotor which rotates about the spool;
- and
- a driving mechanism rotating a driven gear and causing the rotor to rotate and the spool to axially reciprocate for winding a line onto the spool comprising a pinion gear which engages a face gear, said face gear having a plurality of teeth with a tooth form with a cross-section wherein the cross section of an inner pitch portion is less than an outer pitch portion, and the pinion gear engages the inner pitch portion in a contact area less than the outer pitch portion.
1 more element
A driving mechanism for a fishing reel comprising:
- a face gear which rotates about a first axis and has a plurality of teeth having a tooth form with a cross-section wherein the cross-section of a radial inner pitch portion is less than a radial outer pitch portion;
- and
- a pinion gear which rotates about a second axis offset from said first axis and perpendicular to said first axis and engages the face gear such that the radial inner pitch portion of the face gear is engaged in a contract area less than the outer radial pitch portion of the face gear.
