Seen in: Kuru Toga Dive
Production status: In Production
Complexity level: Kuru Toga spin mechanism, ball clutch + 3 mechanisms
The Dive is Comprised of Multiple seprate mechanisms, namely:
the Sleeve
the closed Ball Clutch
The Rotation Unit
The decellerator
the Adjustor
Count Rings.
The Rotational Unit Is covered HERE
The closed Ball Clutch is Covered HERE
The sleeve is vertically limited by the tooth ring which sets its minimum point. it is constsntly pushed down by a spring.
Relationships and Assembly
Decelerator Unit
Purpose: To transform the vertical and rotational forces of the Rotational Unit into a slower rotational force onto the top Count Ring
Parts:
a. Input Cam
b. Output cam
The Unit slows the 40 stroke/360 degree rotation to a ~301 stroke/360 degree rotation accoarding to the patent. In reality, tests have concluded this slowdown to be even more pronounced, slowing the 40 stroke/360 degree rotation to a ~440 stroke/360 degree rotation.
The Imput Cam is connected vertically and rotationally to the Middle Rotational Unit while the output cam is fixed vertically and rotationally conected to the top count ring.
Starting the state with the middle rotator in the topmost position, the imput cam ( also in the topmost position) touches the output cam. As writing pressure is released, the middle rotator and thus imput cam travels straight down until the middle rotator meshes with the bottom rotator, rotating the imput cam 4.5 degrees. In this state, since the imput cam is not touching the output cam, this 4.5 degree rotation is not applied to the output cam. As writing pressure is applied once again, the middle rotator moves up until it touches the top cam face. In this state there is a 3.304 degree distance between the imput cam and output cam. The imput cam travels said 3.304 degree without touching the output cam. Once it touches the output cam, it moves the remining 1.196 degrees. It end up in the starting position. As writing pressure is released, is once again moves down, thus the cycle continues.
Through the decelerator as specified in the patent, the 40 stroke/360 degree is transferred to the next part as 360/1.196=approx 301 strokes.
Count Rings
Parts:
Tooth Ring
slope cam
Transfer Part
The Transfer Part is fixed to the output cam of the decellerator unit. As the transfer part rotates with the rotation of the output cam, it transfers this force to the tooth ring. The tooth ring travels around and up the slope cam until it reaches the ledge and drops down. The tooth ring is vertically connected to the sleeve, thus as it travels up, the sleeve is also pulled up, revealing lead. As it drops, the sleeve also drope down, pulling lead out from the ball clutch.
Asjustor.
Parts:
Regulator wall
slope cam
By rotating the regulator wall, the wall spins inside of the slope cam, delaying the drop of the tooth cam and thus also decreasing the drop distance. This reduces both the sleeve retraction distance and the length of the tooth ring fall distance, limiting lead output.
To sum it all up, the rotator spins the lead 360 degrees every 40 strokes, proving the energy for the decelerator unit which transers the rotator's spin to the tooth ring, all while slowing it to some 301 strokes per 360 degrees. The tooth ring travels on the slope cam, pulling the lead sleeve up a set amount, which releases lead every time the tooth ring makes a full rotation. The adjustor dictates the amount of lead released per tooth ring rotation by decreasing the vertical travel distance of the tooth ring. The ball clutch allows the lead to only travel in one direction, transferring the upper vertical motionthe lead recieves while writing to the middle rotator while letting the sleeve pull lead out.
