This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make as ...
Dog clutch used to drive the rotating platter in a microwave oven. Dog clutch (disengaged) on the countershaft gears of the Honda CBR600RR transmission.. A dog clutch (also known as a dog box, dog gears, dog ring, clutch dog, or positive clutch) is a type of clutch that couples two rotating shafts or other rotating components by engagement of interlocking teeth or dogs rather than by friction.
A lathe dog is a mechanical device typically made of cast iron, steel or aluminum that transmits rotary motion from a faceplate to a workpiece mounted between centers in a lathe. [1] The tail of the dog is rotated by a slot in a driving faceplate, a stud mounted on a faceplate, or sometimes a side of a chuck jaw.
and it is seen that the output drive is just 90 degrees out of phase with the input shaft, yielding a constant-velocity drive. NOTE: The reference for measuring angles of input and output shafts of universal joint are mutually perpendicular axes. So, in absolute sense the forks of the intermediate shaft are parallel to each other.
Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1] In modern equipment this can be achieved by a hydraulics , but pulleys are generally used for simpler designs such as extendable ladders and amateur ...
Telescopic cylinders require careful design as they are subjected to large side forces especially at full extension. The weight of the steel bodies and the hydraulic oil contained within the actuator create moment loads on the bearing surfaces between stages. These forces, combined with the load being pushed, threaten to bind or even buckle the ...
The collar of a cane may be only a decorative addition made for stylistic reasons, or may form the structural interface between shaft and handle. Shaft. The shaft of the cane transmits the load from the handle to the ferrule and may be constructed from carbon fiber polymer, metal, composites, or traditional wood. Ferrule. The tip of a cane ...
Dogcart with horses in tandem. A dogcart (also dog-cart or dog cart) is a two-wheeled horse-drawn vehicle pulled by a single horse in shafts, or driven tandem.With seating for four, it was designed for sporting shooters and their gun dogs, with a louvred box under the driver's seat to contain dogs.
