Have you ever tried cycling uphill? It’s really a tough task unless you use the right gear to increase your climbing force upwards.
Gears are used in machines of all kinds, not just cars and bicycles, but in toys, clocks, mixers, bikes, and oil rigs. Gears are essential for these, and many other, applications because they can generate more speed or power, or change the direction of power.
At its most basic, a gear consists of a series of teeth on a wheel, and this basic fact makes gear manufacturing one of the most complicated metal cutting processes out there. Gears should always have robust construction, reliable performance, high efficiency, and a long life. Also, gears should be fatigue- and stress-free to avoid failure which could lead to disastrous conditions.
In a report by Technavio, analysts forecast that the global gear manufacturing market will grow at a CAGR of 5.33 percent between 2014 and 2019.
Key Market Drivers
According to this report, one of the key factors contributing to this market growth is the rising demand for manual gearing in the oil and gas industry. The other driver fueling this growth are an increased demand for gears from the power and automotive industry.
Another market highlight is the increasing demand for spur gears. However, the high risk of potential accidents presents a challenge to the growth of the spur gear market.
To increase productivity, industries in developed countries including chemical, power, pulp and paper, oil and gas, and textile have started upgrading old gears and replacing them with new and innovative gear designs. Additionally, this will help these industries reduce their overall operational costs by lowering equipment maintenance costs.
The key regions where the top companies manufacturing gears are located include the Americas, EMEA (Europe, the Middle East, and Africa), and APAC (Asia-Pacific).
In another report by Statista, global demand for gears is expected to grow to 217 billion U.S. dollars by 2018. The key players in this field include General Motors, ZF Friedrichshafen, and Volkswagen .
The global gear manufacturing market can be further divided into three important product segments:
A worm gear is a gear arrangement in which a worm meshes with a worm gear. The two elements of the arrangement are a worm screw and worm wheel. Worm gears are used when large gear reductions are needed.
These are a gear arrangement where the axes of the two shafts intersect. The tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are mostly used mounted on shafts that are 90 degrees apart, but they can be designed to work at other angles as well. When the direction of a shaft’s rotation needs to be changed, bevel gears are used.
This is the most common type of gear arrangement. They have straight teeth, and are mounted on parallel shafts. To create very large gear reductions, many spur gears are used at a time. Spur gears are used in many everyday devices like electric screwdrivers, garden sprinklers, and winding alarm clocks.
The demand for industry specific gears and an increase in technical expertise are the two market trends which are propelling growth in the global gear manufacturing market. This is an indication that the global gear manufacturing market will only be growing in the years to come.
