Groschopp offers torque hands on right angle gearboxes to provide a pivoted connection source between your gearbox and a fixed, stable anchor level. The torque arm is used to resist torque developed by the gearbox. In other words, it prevents counter rotation of a shaft installed speed reducer (SMSR) during operation of the application.
Unlike various other torque arms which may be troublesome for some angles, the Arc universal torque arm enables you to always position the axle lever at 90 degrees, providing you the the majority of amount of mechanical advantage. The spline design enables you to rotate the torque arm lever to nearly every point. This is also helpful if your fork scenario is a little trickier than normal! Functions ideal for front and backside hub motors. Protect your dropouts – get the Arc arm! Made from precision laser slice 6mm stainless 316 for excellent mechanical hardness. Includes washers to hold the spline section, hose clamps and fasteners.
A torque arm can be an extra piece of support metal added to a bicycle body to more securely contain the axle of a robust hubmotor. But let’s rear up and get some good even more perspective on torque hands generally to learn if they are necessary and why they will be so important.
Many people decide to convert a typical pedal bicycle into an electric bicycle to save money over investing in a retail . This is a great option for numerous reasons and is surprisingly easy to do. Many manufacturers have designed simple alteration kits that can easily bolt onto a typical bike to convert it into an electric bicycle. The only problem is that the poor man that designed your bicycle planned for it to be utilized 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 an electric hubmotor. You see, common bicycle wheels don’t apply very much torque to the bicycle dropouts. Front wheels truly don’t apply any torque, so the front fork of a bicycle is made to simply hold the wheel in place, certainly not resist its torque although it powers the bike with the drive of multiple Torque Arm china specialist cyclists.
Rear wheels on typical bicycles traditionally do apply a tiny amount of torque on 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 usually are fine. Even front forks are designed for the low 
torque of these hubmotors. Once you start getting 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 weaker, as in lightweight aluminum forks.
