A motorcycle handlebar is a tubular component of a motorcycle's steering mechanism. Handlebars provide a mounting place for controls such as brake, throttle, clutch, horn, light switches and rear view mirrors; and they help to support part of the rider's weight. Even when a handlebar is a single piece it is usually referred to in the plural as ...
The torque applied to the fastener must be determined such that it does not contribute to a service condition where the fastener enters a low-cycle fatigue regime. In general, the use of torque-to-yield fasteners is deprecated except in cases where the materials and structures comprising the entire assembly are certified to be within tolerances ...
BS 811: 1950 provides specifications for British standard cycle threads. [2] Cycle thread in 7 ⁄ 16 and 1 ⁄ 2 inch sizes also come in 20 tpi and 24 tpi options. 1/4" diameter cycle thread nuts and bolts have the same 26tpi as 1/4" BSF, which means that they will fit each other in this diameter only. Traditionally the parts it would be found ...
A bolt that is threaded all the way to the head. An ASME B18.2.1 compliant set/tap bolt has the same tolerances as an ASME B18.2.1 compliant hex cap screw. set screw: grub screw: A set screw is generally a headless screw but can be any screw used to fix a rotating part to a shaft, such as a line shaft or countershaft. The set screw is driven ...
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
Most torque screwdrivers allow the torque to be set to any value within a range. All have a torque-limiting clutch that disengages once the preset torque has been reached. Torque screwdrivers can exert torques from 0.04 N⋅m to at least 27 N⋅m. [1] Although no single tool covers the entire range, low-, mid-, and high-torque ranges are available.
The Harley-Davidson Sportster is a line of motorcycles produced continuously since 1957 by Harley-Davidson. Sportster models are designated in Harley-Davidson's product code by beginning with "XL". In 1952, the predecessors to the Sportster, the Model K Sport and Sport Solo motorcycles, were introduced.
Ball bearings are an example of an attempt to minimize the friction torque. [2] Friction torque can also be an asset in engineering. Bolts and nuts, or screws are often designed to be fastened with a given amount of torque, where the friction is adequate during use or operation for the bolt, nut, or screw to remain safely fastened.
