Torque Arm

Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection source between the gearbox and a fixed, stable anchor level. The torque arm is used to resist torque produced by the gearbox. Basically, it prevents counter rotation of a shaft attached quickness reducer (SMSR) during operation of the application.
Unlike additional torque arms which is often troublesome for a few angles, the Arc universal torque arm permits you to always position the axle lever at 90 degrees, giving you the most amount of mechanical advantage. The spline style permits you to rotate the torque arm lever to almost any point. That is also helpful if your fork circumstances is just a little trickier than normal! Works great for front and back hub motors. Protect your dropouts – obtain the Arc arm! Created from precision laser slice 6mm stainless steel 316 for superb mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.
A torque arm is an extra piece of support metal added to a bicycle framework to more securely contain the axle of a powerful hubmotor. But let’s rear up and get some even more perspective on torque hands generally to learn when they are necessary and just why they are so important.

Many people decide to convert a standard pedal bicycle into a power bicycle to save lots of money over purchasing a retail . This is normally an excellent option for a number of reasons and is surprisingly simple to do. Many makers have designed simple alteration kits that can certainly bolt onto a standard bicycle to convert it into a power bicycle. The only problem is that the indegent guy that designed your bike planned for this to be used with lightweight bike tires, not giant electrical hub motors. But don’t fret, that’s where torque arms come in!
Torque arms are there to help your bicycle’s dropouts (the part of the bike that holds onto the axles of the wheels) resist the torque of an electric hubmotor. You see, typical bicycle wheels don’t apply very much torque to the bike dropouts. Front wheels essentially don’t apply any torque, so the front side fork of a bike is designed to simply contain the wheel in place, not resist its torque although it powers the bike with the pressure of multiple professional cyclists.

Rear wheels on typical bicycles traditionally do apply a tiny amount of torque upon the dropouts, but not more than the typical axle bolts clamped against the dropouts can handle.
When you swap in an electric hub engine though, that’s when torque becomes a concern. Small motors of 250 watts or much less are usually fine. Even front forks can handle the low torque of the hubmotors. Once you strat to get up to about 500 watts is when concerns may appear, especially if we’re discussing front forks and much more so when the material is weaker, as in aluminium forks.
