A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
Radial run-out is caused by the tool being translated off the machine axis, still parallel. Radial run-out will measure the same all along the machine axis. Axial run-out is caused by the tool or component being at an angle to the axis. Axial run-out causes the tip of the tool or shaft to rotate off-centre relative to the base.
The reduced shift travel provided by the synchroniser package has also allowed increased space for the use of larger gears, which are stronger to deliver improved torque capacity and gearbox durability. A new single-piece counter shaft also contributes to the greater torque capacity and durability enhancements.
The HM290 and 5LM60 units have a complicated arrangement of 4 shift rails. The NV3500 has one shift rail. [2] There are two designs for the 5LM60 input shaft and bearings (input shaft and main shaft). The first design 1988–1990 has a ball bearing with a roller bearing behind it. The second design has a much larger single ball bearing.
Based on an 81mm center distance, the TR-3160 utilizes high strength steel on all gears and shafts - maximizing torque capacity and durability while minimizing weight and package size. High capacity tapered bearings and high capacity synchronizers contribute to low shift efforts and shifter travel. All gears are hard-finished.
The 420G is a 6-speed manual transmission manufactured by Getrag. It is designed for longitudinal engine applications and for use on engines producing up to 499 N⋅m (368 lb⋅ft) of torque. BMW used this transmission with M60 V8 models such as the European manual 840i, European manual 740i, 540i; [ 1 ] as well as the M62 powered 5 series ...
The following stresses are induced in the shafts. Shear stresses due to the transmission of torque (due to torsional load). Bending stresses (tensile or compressive) due to the forces acting upon the machine elements like gears and pulleys as well as the self weight of the shaft. Stresses due to combined torsional and bending loads.
Radial shaft seals, also known as lip seals, are used to seal rotary elements, such as a shaft or rotating bore. Common examples include strut seals, hydraulic pump seals, axle seals, power steering seals, and valve stem seals. Early radial shaft seals utilized rawhide as the sealing element, and many present-day elastomeric seal companies were ...
