Groschopp offers torque arms on right angle gearboxes to provide a pivoted connection Torque Arm china source between the gearbox and a set, 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 installed quickness reducer (SMSR) during operation of the application.
Unlike additional 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 design enables you to rotate the torque arm lever to nearly every point. This is also convenient if your fork situation is just a little trickier than normal! Performs great for front and backside hub motors. Protect your dropouts – get the Arc arm! Made from precision laser minimize 6mm stainless steel 316 for good 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 body to more securely contain the axle of a powerful hubmotor. But let’s again up and get some even more perspective on torque arms on the whole to learn if they are necessary and just why they are so important.

Many people want to convert a typical pedal bicycle into a power bicycle to save money over investing in a retail . This is normally a great option for several reasons and is remarkably easy to do. Many manufacturers have designed simple conversion kits that can easily bolt onto a standard bicycle to convert it into a power bicycle. The only difficulty is that the indegent 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 can be found in!
Torque arms is there to greatly 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, normal bicycle wheels don’t apply much torque to the bicycle dropouts. Front wheels in fact don’t apply any torque, therefore the the front fork of a bicycle is designed to simply contain the wheel in place, not resist its torque although it powers the bike with the drive of multiple professional cyclists.

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