Title:
TAKE-UP REEL
Document Type and Number:
Japanese Patent JPH06329340
Kind Code:
A
Abstract:

PURPOSE: To prevent malfunction by making the raceway surfaces of an inner ring for supporting a reel main body in a fixed position in the direction of center axis in such a manner as to freely rotate and an outer ring opposite to the inner ring as a univalent hyperboloid of revolution, disposing plural rollers in the raceways formed by both rings, and providing the outer ring with energizing means for reducing and enlarging the raceway space and a torque transmitting means.

CONSTITUTION: A reel main body part 100 having a winding surface 100a and a ratchet 100b is supported in a fixed position in the direction of center axis in such a manner as to freely rotate. An inner ring 1 has an inner ring raceway surface 1a forming a univalent hyperboloid of revolution, and forms a raceway 4 with an outer ring 2 having the similar outer ring raceway surface 2a. Plural rollers 3 are disposed with a gradient to the peripheral direction on the raceway 4 in such a manner as to come into line contact with both racewayt surface 1a, 2a. The reel is further provided with a torque spring 5 for transmitting torque between the outer ring 2 and the main body part 2 and reducing the raceway 4 space, an intermediate member 6 for energizing to widen the raceway space and a pressing member 7.
