Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection supply between your gearbox and a fixed, stable anchor level. The torque arm is employed to resist torque produced by the gearbox. In other words, it prevents counter rotation of a shaft mounted rate reducer (SMSR) during operation of the application.
Unlike additional torque arms which may be troublesome for some angles, the Arc universal torque arm allows you to always position the axle lever at 90 degrees, providing you the many amount of mechanical advantage. The spline style enables you to rotate the torque arm lever to nearly every point. This is also convenient if your fork scenario is just a little trickier than normal! Works great for front and back hub motors. Protect your dropouts – receive the Arc arm! Created from precision laser slice 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 little bit of support metal put into a bicycle body to more securely hold the axle of a Torque Arm china powerful hubmotor. But let’s rear up and get some more perspective on torque arms in general to learn when they are necessary and why they will be so important.

Many people choose to convert a standard pedal bicycle into an electric bicycle to save lots of money over investing in a retail . This is certainly a great option for a number of reasons and is surprisingly simple to do. Many manufacturers have designed simple conversion kits that can simply bolt onto a standard bicycle to convert it into an electric bicycle. The only difficulty is that the indegent man that designed your bicycle planned for this to be used with lightweight bike tires, not giant electric hub motors. But don’t fret, that’s where torque arms come 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 an electric hubmotor. You see, usual bicycle wheels don’t apply very much torque to the bicycle dropouts. Front wheels truly don’t apply any torque, therefore the entrance fork of a bike is designed to simply hold the wheel in place, not really resist its torque although it powers the bike with the drive of multiple professional cyclists.

Rear wheels on standard bicycles traditionally do apply a small amount of torque about the dropouts, however, 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 turns into an issue. Small motors of 250 watts or significantly less are usually fine. Even the front forks are designed for the low torque of these hubmotors. Once you start getting up to about 500 watts is when complications can occur, especially if we’re discussing front forks and even more so when the material is usually weaker, as in metal forks.
