High strength epoxy adhesives are used in fabrication of carbon fiber composite drive shafts for cars. [1] The metal inserts provide support for bearings, shafts, gears and other metal components of the gearbox. The composite gear housing does not remove heat as efficiently as an aluminum or magnesium housing. Composite gear housings require ...
Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in double helical gears where the total face width includes any distance or gap separating right hand and left hand helices. For a cylindrical gear, effective face width is the portion that contacts the mating teeth.
VEX V5 Robotics Competition (previously VEX EDR, VRC) is for middle and high school students. This is the largest league of the four. This is the largest league of the four. VEX Robotics teams have an opportunity to compete annually in the VEX V5 Robotics Competition (V5RC) [ 3 ]
TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...
high torque capability, coaxial input and output shafts. [2] High gear reduction ratios are possible in a small volume (a ratio from 30:1 up to 320:1 is possible in the same space in which planetary gears typically only produce a 10:1 ratio). Disadvantages include a tendency for 'wind-up' (a torsional spring rate) in the low torque region.
The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.
The Enhanced Small Arms Protective Inserts (ESAPIs) and Enhanced Side Ballistic Inserts (ESBIs) have become available, along with the Deltoid and Axillary Protector System (DAPS). These new systems are becoming the standard for forward deployed troops. The E-SAPI plates offer increased protection from 7.62mm armor-piercing ammunition. The ESBIs ...
Isometric projection of a grub screw with a hex socket head.. Set screws are not always the best way to resist the torque of driven shafts. To reduce the chance of slipping and to increase load capacity, a detent (often called a "flat") may be milled or ground at the part of the shaft where the set screw's point contacts.
