Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection resource between your gearbox and a set, stable anchor point. The torque arm is utilized to resist torque produced by the gearbox. In other words, it prevents counter rotation of a shaft installed acceleration reducer (SMSR) during operation of the application.
Unlike other torque arms that can be troublesome for a few angles, the Arc universal torque arm permits you to always position the axle lever at 90 degrees, providing you the many amount of mechanical advantage. The spline design and style permits you to rotate the torque arm lever to almost any point. That is also helpful if your fork situation is just a little trickier than normal! Performs ideal for front and rear hub motors. Protect your dropouts – receive the Arc arm! Made from precision laser slice 6mm stainless steel 316 for remarkable mechanical hardness. Includes washers to hold the spline section, hose clamps and fasteners.
A torque arm is an extra little bit of support metal added to a bicycle frame to more securely contain the axle of a robust hubmotor. But let’s rear up and get some good more perspective on torque arms generally speaking to learn when they are necessary and just why they are so important.

Many people tend to convert a standard pedal bicycle into an electric bicycle to save lots of money over purchasing a retail . This is certainly an excellent option for numerous reasons and is surprisingly simple to do. Many makers have designed simple alteration kits that can easily bolt onto a standard bicycle to convert it into a power bicycle. The only issue is that the poor guy that designed your bicycle planned for this to be utilized with lightweight bike wheels, not giant electric hub motors. But don’t be concerned, that’s where torque arms can be found in!
Torque arms is there to help your bicycle’s dropouts (the part of the bike that holds onto the axles of the wheels) resist the torque of a power hubmotor. You see, regular bicycle wheels don’t apply very much torque to the bicycle dropouts. Front wheels essentially don’t apply any torque, so the front fork of a bicycle is designed to simply contain the wheel in place, certainly not resist its torque although it powers the bike with the push of multiple specialist cyclists.

Rear wheels on common bicycles traditionally do apply a small amount of torque on 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 fewer usually are fine. Even front side forks are designed for the low torque of the hubmotors. Once you strat to get up to about 500 watts is when complications may appear, especially if we’re discussing front forks and even more so when the materials is normally weaker, as in light weight aluminum forks.
