Global Gear Couplings Market 2017-2021
About Gear Couplings
Gear couplings are a type of flexible couplings that have forged sleeves. In addition, they are equipped with two hubs with teeth for transmitting torque from the motor to the driven shaft. The global couplings market is the parent market of the global gear couplings market, which includes elastomeric coupling, mechanical couplings, and metallic couplings. Couplings are an integral part of power transmission systems and are used for connecting the shaft of the driving and driven impellers. Couplings ensure the transmission of power and torque from one shaft to another, without any loss of energy and wear and tear of systems.
Technavio’s analysts forecast the global gear couplings market to grow at a CAGR of 4.67% during the period 2017-2021.

Commenting on the report, an analyst from Technavio’s team said: “The latest trend gaining momentum in the market is Emerging trends in curved-tooth and continuous sleeved gear couplings. Gear couplings with curved-tooth provide protection to the connected shaft against angular and parallel misalignment. In high torque applications, power transmission systems require proper alignment of shafts. Curved-tooth gear couplings provide a permissible angular misalignment of up to 1.5 degrees. Curved gear couplings provide high rigid design and temperature resistance of more than 100ºC and ensure ease of installation in harsh environmental conditions.”
According to the report, one of the major drivers for this market is Increased use in high speed and high torque applications. Gear couplings offer advantages, such as high torque density and torsional stiffness. In addition, they can handle slight misalignment in the shaft. As gear couplings offer torsional rigidity, they are mainly used in high-speed applications in oil and gas, mining and metals, and heavy machinery industries. The crowning of the teeth in the gear coupling allows for misalignment, although the misalignment capacity is mainly dependent on the curve of the gear teeth.
Further, the report states that one of the major factors hindering the growth of this market is Lubrication and misalignment related issues. The most important operating factor for a gear coupling to be reliable is lubrication. The gear teeth need to be lubricated, and the lack of lubrication may lead to gear coupling failure. Insufficient lubrication may loosen small metal parts of the gear coupling, and lead to fretting corrosion. Depending on the design, gear couplings may either be grease or oil lubricated. The use of grease or oil provides viscosity for the smooth operation of the gear coupling. The lubricant may become too thick or too thin to reach through the teeth mesh. Hence, lubrication is a major challenge for the global gear couplings market. Many industrial manufacturers prefer non-lubricated couplings over lubricated couplings, such as gear and chain couplings as they require less maintenance than lubricated couplings, such as gear couplings.
