Small Precison Worm Decrease Gearboxes
There are many of specifications you will have to consider when making a worm gearbox selection.
First, what’s the input and output torque requirements? Next, verify vendor horsepower/torque charts and select the correct worm equipment reducer.
If the size of the gearbox will be an important consideration after that check the reducer dimension specs, not all manufacturers make compact units. Actually, working with the proper supplier will help you not only find the right equipment reducer but also avoid some of the most common errors in reducer selection. We offer a free guide to assist you find the right supplier to utilize.
For low and fractional horsepower application you can expect two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output will be the major distinctions between both of these models. Both feature either a hollow or solid result shaft. Both models are compact and offer users an array of ratios, including:
SW-1, 3.5:1 to 60:1
SW-5, 5:1 to 100:1
Understanding the specs of your unique application or task is essential to selecting the correct worm gearbox.
