I always wondered how it’s physically possible to assemble two yokes and a cross to make a universal joint. Can someone smarter than me explain the process? The geometry of assembly seems impossible.

“In electronics, a choke is an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC). A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped “bead” of ferrite material strung on a wire. The choke’s impedance increases with frequency. Its low electrical resistance passes both AC and DC with little power loss, but its reactance limits the amount of AC passed.”.

The STL files [Marius] has provided for his low-friction hubs should work fine for anyone who’s interested in trying out his design, but you’ll need to come up with your own method of mounting the 8 mm rod in a convenient place. The arms he’s included are specifically designed for his customized Prusa Mendel, which is pretty far removed from contemporary desktop 3D printer design. Something to consider might be a piece of 8 mm rod suspended over the printer, with enough space that you could put a couple spools on for quick access to different colors or materials.

I worked at a company in the ’80s that had a product that used a 2 cylinder Briggs and Straton engine that drove a roots style blower. It worked great and had done so for years. One of our customers wanted a smaller version, so we built one with a smaller one cylinder motor and a smaller blower. It didn’t work so well. With half the power strokes on the engine and a smaller blower, a resonance occurred that would destroy every coupling that was used between the units. Some threw shrapnel violently across the lab, the ones with rubber lasted a bit longer, but eventually, the rubber got so hot that it failed. Sometimes it shot rubber balls out of the coupling shortly before total failure. The resonance was obvious, but the ME working on it and the GM of the company just kept trying new couplers. I suggested machining a flywheel to go on the blower side of the coupling to try and change the frequency that the resonance became serious at. I had two strikes against me. I was a student, and I was majoring in EE, so the ME blew me off. I still think it would have been worth a try, it would be easy and wouldn’t have left us worse off if it didn’t work. I left the company a year later, and the prototype was sitting in the corner of the lab collecting dust.

Vancouver, British Columbia–(Newsfile Corp. – March 18, 2019) – Bearing Lithium Corp. (TSXV: BRZ) (OTCQB: BLILF) (FSE: B6K2) ("Bearing" or the "Company") announces that, subject to approval by the TSX Venture Exchange, it intends to amend the terms of a total of 4,565,000 outstanding share purchase warrants (the "Warrants") issued pursuant to a private placement that closed in two tranches on August 8, 2019 and August 16, 2019. Each Warrant is currently exercisable for one common share of Bearing at an exercise price of $0.40 per share. If approved, the proposed amendment will reduce the exercise price of the Warrants to $0.31 per share.

The axial cracking failure mode of a bearing mainly occurs on the inner ring typically mounted to a shaft with an interference fit. The ring is heated during assembly onto the shaft. When the ring cools, it shrinks – holding the itself in place, but also creating tensile stress in the ring that increases the possibilities for axial cracking.

If there’s any chance of misalignment between shafts, though, a flexible coupling is called for. While not designed for transmitting torque through a wide angle, flexible couplings do allow shafts to get as much as a few degrees out of alignment without causing damage. This is important in devices where vibration or flexibility in the structure is likely to let the shafts move slightly relative to each other, like on my log splitter. In that case, the shafts were coupled by a jaw coupling, often known by the trade name Lovejoy. Lovejoy couplings have two metal halves with castellations that nest within each other. The metal is prevented from contacting directly by a tough elastomeric spider which both cushions rapid changes in torque and allows the shafts to flex a bit.
