In northern Europe, the spur became less elaborate after the 16th century, particularly following the Stuart Restoration, but elaborate spur designs persisted, particularly in the Americas, descendants of which are still seen today, particularly in Mexico and the western United States, where the spur has become an integral part of the vaquero ...
A spur is an outgrowth of bone covered in a sheath of horn found in various anatomical locations in some animals. Unlike claws or nails, which grow from the tip of the toes, spurs form from other parts of the foot, usually in connection with joints where the toes meet the foot or the foot meets the long bones.

Spur gear. Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is ...
Two intermeshing spur gears rotating at different velocity due to differing gear ratio. A gear [1] [2] or gearwheel [3] [4] [5] is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part.
Lead angle is 90° to the helix angle between the helical tooth face and an equivalent spur tooth face. For the same lead, the lead angle is larger for smaller gear diameters. It is understood to be measured at the standard pitch diameter unless otherwise specified. A spur gear tooth has a lead angle of 90°, and a helix angle of 0°. See ...
Spur-gear differential. A spur-gear differential has an equal-sized spur gears at each end, each of which is connected to an output shaft. [8] The input torque (i.e. from the engine or transmission) is applied to the differential via the rotating carrier. [8] Pinion pairs are located within the carrier and rotate freely on pins supported by the ...
The venom-delivering spur is found only on the male's hind limbs. The platypus is one of the few living mammals to produce venom.The venom is made in venom glands that are connected to hollow spurs on their hind legs; it is primarily made during the mating season. [1]
If mounted on a Layshaft it is called a Spur Wheel and only drives one Stone Nut Hurst Frame An internal framework supporting the gears and millstones. This isolation prevents damage to the building from the vibrations of the workings. Layshaft A Layshaft in a watermill is a horizontal shaft, carrying a Wallower and one or more Spur Wheels. The ...
