3 Types Of Multi-Turn Spur Gearboxes You Should Know About

Multi-turn spur gearboxes are one of the famous precision cylindrical gears. These gearboxes feature simple designs hosting a central bore on the shaft. One of the primary reasons industries use multi-turn spur gears in several mechanical activities is to regulate the device’s speed by either increasing or decreasing it. Another reason is to multiply the torque capacity by using gears to transmit power between shafts.

Easy-to-understand design, reliability, cost-effectiveness, and efficiency are some benefits of these gearboxes manufactured by any leading multi-turn spur gearbox manufacturer. Let us now look into types of multi-turn spur gearboxes that can benefit your industry.

• Multi-Turn Spur Gearbox For Non-Rising Stem (Manual Or Hand-Wheel Operation)

Multi-turn spur gearbox manufacturers in USA design this gearbox in several models, allowing customers to choose one as per their industrial needs and the specifications they require. Generally, the output torque capacity of the base model stands at 300 newton-meters (nm) and 221 pound-feet (lb-ft). On the contrary, the output torque capacity of the last model stands at 40,000 nm and 29,502 lb-ft.

The hand-wheel diameter of this gearbox can be anywhere between 400 mm or 16 inches to 1,000 mm or 40 inches. Moreover, the hand-wheel effort can range anywhere from 128 lbs or 57 kg to 682/852 lbs or 309/387 kg.

• Multi-Turn Spur Gearbox For Non-Rising Stem (Actuator Operation)

Unlike the previous spur gearbox for manual or hand-wheel operation, this gearbox by known manufacturers like Viral Industries is made to meet the needs of actuator operation. This gearbox is also available in several models, with the minimum output torque capacity being 300 nm or 221 lb-ft and the maximum being 40,000 nm or 29,502 lb-ft.

This gearbox also features input toque capacity in newton meters and inches, wherein the value of the base model stands at 114 nm or 84 inches, and the value of the last model stands at 1515/1894 nm or 1118/1397 inches.

• Multi-Turn Spur Gearbox For Rising Type Stem

This gearbox from manufacturers like Viral Industries can be used for the rising stem of the gate, globe, or check valve. It features a removable adopter sleeve made from aluminum bronze. In addition, the hand wheel is top mounted, and you can convert the gearbox for carrying the actuator operations. One thing to note about this gearbox is that it hosts a clockwise input and output feature.

The rising type stem’s thrust capacity varies with models but generally ranges between 90 to 4800 kilonewton (kn).

Wrapping Up

Multi-turn spur gearboxes are used across industries to meet their mechanical demands. Each model and type of this varies in terms of features, advantages, applications, and disadvantages. However, to make the best use of these gearboxes, you need to pay attention to the quality at the time of purchase, which means you cannot afford to compromise on the manufacturer you choose.

So, we are ending this article by recommending a manufacturer that is none other than Viral Industries, known for its gears across the USA. Don’t forget to contact them if you want to purchase a multi-turn spur gearbox.
