Torque Arm

Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection resource between your gearbox and a fixed, 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 mounted rate reducer (SMSR) during operation of the application.
Unlike various other torque arms which may be troublesome for a few angles, the Arc universal torque arm enables 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 useful if your fork problem is just a little trickier than normal! Works ideal for front and rear hub motors. Protect your dropouts – get the Arc arm! Created from precision laser trim 6mm stainless 316 for good 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 body to more securely hold the axle of a robust hubmotor. But let’s again up and get some good even more perspective on torque arms generally speaking to learn when they are necessary and just why they happen to be so important.

Many people choose to convert a standard pedal bicycle into an electric bicycle to save money over purchasing a retail . This is definitely an excellent option for several reasons and is amazingly easy to do. Many companies have designed simple alteration kits that can easily bolt onto a typical bicycle to convert it into a power bicycle. The only problem is that the poor person that designed your bike planned for this to be used with lightweight bike wheels, not giant electric hub motors. But don’t worry, that’s where torque arms come in!
Torque arms is there to greatly help your bicycle’s dropouts (the area of the bike that holds onto the axles of the wheels) resist the torque of a power hubmotor. You see, normal bicycle tires don’t apply much torque to the bicycle dropouts. Front wheels in fact don’t apply any torque, so the entrance fork of a bicycle is built to simply hold the wheel in place, not resist its torque while it powers the bike with the push of multiple professional cyclists.

Rear wheels on common bicycles traditionally do apply a small amount of torque in the dropouts, however, not more than the standard axle bolts clamped against the dropouts are designed for.
When you swap within an electric hub motor though, that’s when torque becomes a concern. Small motors of 250 watts or less are generally fine. Even entrance forks can handle the low torque of these hubmotors. Once you strat to get up to about 500 watts is when problems can occur, especially if we’re talking about front forks and even more so when the materials is definitely weaker, as in metal forks.
