fig.1. A duplex worm or dual lead worm is a worm gear set where the two flanks are manufactured with slightly different modules and/or diameter quotients. As a result of this, different lead angles on both tooth profiles are obtained, so that the tooth thickness is continuously increasing all over the worm length, while the gap between two threads is decreasing.
An older design baitcasting reel – the ABU Garcia Ambassadeur A more modern baitcasting reel. The baitcasting reel or baitcaster is a multiplying reel like modified from the conventional reel, but with a lighter spool and a higher, more forwardly positioned line guide to facilitate farther and smoother casting, hence the name.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
Backlash is a mechanical form of deadband. Gear teeth with slop exhibit deadband. There is no drive from the input to the output shaft in either direction while the teeth are not meshed. Leadscrews generally also have backlash and hence a deadband, which must be taken into account when making position adjustments, especially with CNC systems ...
A pair of ABU reels from the end of the 1960s; the smaller is the Cardinal 33, the larger is the Cardinal 66, and the Swedish royal coat of arms, a right conferred by Royal Warrant, can be seen clearly.
Harmonic Drive SE strain wave gear set consisting of wave generator bearing (top left), flexspline cup (top right) and circular spline ring (bottom). Strain wave gearing (also known as harmonic gearing ) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage ...
This influences not only the casting and the fish-fighting properties, but also the sensitivity to strikes when fishing lures, the ability to set a hook (which is also related to the mass of the rod), the control over the lure or bait, the way the rod should be handled and how the power is distributed over the rod.
To obtain an accurate clear sighting, the cross hairs should be in focus; adjust the eyepiece to do this. Focusing of eyepiece lens For focusing of the eye piece, point the telescope to the sky or hold a piece of white paper in front of telescope. Move the eye-piece in and out until a distinct sharp black image of the cross-hairs is seen.
