Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection supply between the gearbox and a fixed, stable anchor stage. The torque arm is utilized to resist torque produced by the gearbox. In other words, it prevents counter rotation of a shaft mounted rate reducer (SMSR) during procedure of the application.
Unlike various other torque arms which can be troublesome for some angles, the Arc universal torque arm allows you to always position the axle lever at 90 degrees, providing you the most amount of mechanical advantage. The spline style permits you to rotate the torque arm lever to nearly every point. That is also useful if your fork scenario is a little trickier than normal! Works great for front and rear hub motors. Protect your dropouts – get the Arc arm! Made from precision laser lower 6mm stainless steel 316 for excellent mechanical hardness. Includes washers to hold 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 hold the axle of a robust hubmotor. But let’s rear up and get some more perspective on torque hands generally to learn when they are necessary and why they will be so important.

Many people want to convert a typical pedal bicycle into an electric bicycle to save lots of money over investing in a retail . This is a great option for several reasons and is remarkably easy to do. Many suppliers have designed simple conversion kits that can easily bolt onto a typical bicycle to convert it into a power bicycle. The only issue is that the poor dude that designed your bicycle planned for this to be utilized with lightweight bike tires, not giant electrical hub motors. But don’t be concerned, that’s where torque arms can be found in!
Torque arms are there to help your bicycle’s dropouts (the area of the bike that holds onto the axles of the wheels) resist the torque of an electric hubmotor. You see, typical bicycle tires don’t apply much torque to the bike dropouts. Front wheels actually don’t apply any torque, therefore the front side fork of a bicycle is designed to simply contain the wheel in place, not resist its torque while it powers the bike with the push of multiple professional cyclists.

Rear wheels on standard bicycles traditionally do apply a tiny amount of torque in the dropouts, but not more than the standard axle bolts clamped against the dropouts can handle.
When you swap within an electric hub electric motor Torque Arm china though, that’s when torque turns into a concern. Small motors of 250 watts or a lesser amount of are often fine. Even front side forks can handle the low torque of these hubmotors. Once you strat to get up to about 500 watts is when complications may appear, especially if we’re discussing front forks and much more so when the materials is weaker, as in light weight aluminum forks.
