Gear Reducers in Industrial Sectors

Gear reducers can substantially boost the amount of torque that a motor produces and may effectively convert the engine's energy into useful force. The devices are also able to decrease the incoming power and to rapidly transfer energy to other moving components. Many gearboxes feature right angles or inline gears, and when searching for gear reducers, a business owner should consider the rotational speed that a gearbox can handle, each device's gear ratio, the backlash, the torque that each gear may generate, the efficiency and the shock loads that each gearbox can withstand.

Planetary Gears

An epicyclic gear consists of a central component, gears that swiftly rotate around the middle device and a ring gear that is connected to the revolving parts. Planetary gears can produce a more substantial reduction in speed than bevel gears and spur gears, and in spite of their low weight, epicyclic gears generate especially high levels of torque and can allow a gearbox's efficiency to exceed 90 percent.

Most planetary gears have a relatively small size, yet they feature a low moment of inertia, which indicates a device's ability to withstand the effects of rapid acceleration. Additionally, the gearboxes can handle more weight because the load's weight is evenly handled by the central component, the sun gears and the ring gear.

Gear Reducers That Feature Worm Gears

These gearboxes are designed for sizable motors that require substantial reductions in speed, and the gear reducers are able to handle high shock loads, which may occur when a moving item accelerates or rapidly slows down. If the worm is not rotating, the gearbox can have the same effects as various types of brakes. These gear reducers also produce particularly low levels of noise, and the gearboxes are able to generate more torque than spur gears and bevel gears. In spite of the device's benefits, the efficiency of worm gears generally does not exceed 68 percent.

Worm gears feature right angles and spiral components that have the shape of a screw. Due to their design, the devices can significantly reduce the effects of rapidly shifting weight, and consequently, manufacturers commonly add worm gears to winches and various types of cranes. Furthermore, worm gears are frequently installed in machines that create sheets of steel.

Bevel Gears

These devices are typically added to gear reducers that have right angles, and bevel gears may have straight teeth or curved teeth. When utilizing bevel gears, a business can easily modify the angles of the components, and gearboxes with bevel gears are typically more efficient than the majority of gear reducers. Most bevel gears can handle rotational speeds of less than 1,100 repetitions per minute, and the devices generally have lower ratios than worm gears.

Bevel gears are regularly installed in printers, many types of drills, factories that produce steel and power plants. The devices are also found in differentials, which can allow the wheels of industrial vehicles to spin at varying speeds when the automobiles are moving around corners.

Devices With Spur Gears

Gear reducers that contain spur gears are generally less expensive than other types of gearboxes, and spur gears feature straight teeth and relatively simple designs. According to multiple reports, the gearboxes have comparatively long lifespans when they regularly operate at relatively low speeds. In spite of their benefits, spur gears are loud if they spin at a high rate, and generally, this type of gearbox can only decrease a sizable motor's force if the gear reducer has a large number of spur gears.

The Materials

Many gears feature numerous types of metals, such as cast steel, aluminum and carbon steel, and some devices consist of cast iron, which is especially machinable and may mitigate the effects of wear. Moreover, certain gear reducers are made of durable plastic, and these devices can lessen noise, provide extra lubrication and reduce the costs of routine maintenance.

Choosing a Gear Reducer That Features a Parallel Shaft

Some gearboxes with parallel shafts can have especially high gear ratios and are able to handle rotational speeds of more than 2,400 repetitions per minute. Many of these devices feature tapered bearings, which can decrease the impact of long-term use and may slightly augment the available torque. Generally, these gear reducers have helical gears or spur gears.

Vents and Coatings

By adding a vent to a gearbox, a business can decrease pressure that is caused by changes in temperature and lessen the force that affects the gear reducer's seals. The vents also feature filters that typically prevent dust and moisture from impacting the gearbox's performance. In addition, some companies place coatings on gears, and these compounds may notably augment the gearbox's capacity and eliminate corrosion.

Applications in the Manufacturing Industry

In general, gear reducers are required by lathes, machines that mill durable products, devices that feature drills and machines that can cut materials of all types. In the manufacturing industry, most machines feature bevel gears or helical gears, and many of these gearboxes are compatible with devices that use 1,000 kilowatts to 10,500 kilowatts of electricity.

Gearboxes for Cranes in Various Industries

Overhead cranes commonly utilize planetary gears or helical gears, and cranes feature numerous durable chains, multiple wire ropes and sheaves. Many businesses also manufacture epicyclic gears for railroad cranes, aerial machines, telescopic handlers, devices that feature towers and specialized cranes that are situated in harbors.

Creating Products That Consist of Paper or Plastic

Manufacturers can add gear reducers to devices that modify plastic and paper, and these gears must be compatible with equipment that swiftly positions labels, parts that create small cuts and components that grind the materials. Typically, these machines contain worm gears that provide double envelopment, and consequently, the modified gears can produce more torque than standard worm gears and will generally increase the maximum load that the machine can handle.

Mining

Gearboxes are commonly added to draglines, which utilize pulleys, heavy-duty buckets, cables that drag the containers and multiple ropes. The gearboxes can also be installed in equipment that features sizable conveyor belts, which typically move materials upward and can have a capacity of more than 15,000 tons per hour. Additionally, gear reducers are found in many machines that grind and wash various raw materials.

Gear Pumps

These machines feature gears that can transport various types of liquids, such as oil, hydraulic fluid, soaps, paint, sludge and fluids that contain sodium silicate. Each device has a drive gear and an idler gear, which may modify the shaft's rotation. Currently, some of the most efficient gear pumps can handle a maximum speed of 3,000 repetitions per minute and approximately 250 pounds per square inch of pressure.
