COVID-19 IMPACT

Automotive Gears Market Had a Lower Effect Due to Disruption in Factory Operations  During COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing negative-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

Demand patterns jolted supply chains and restricted factory functioning with the lockdown, so vehicle assembly had to stop, tooling programs got delayed, and product launches were deferred. Travel restrictions also made vendor audits and qualification runs complicated to complete. Shortages of components, especially metals, forgings, and precision bearings, created scheduling volatility and issues with forced redesign or forced dual-sourcing. OEMs and tier suppliers focused on cash preservation, thereby slashing CAPEX levels that now delay modernization while MRO orders helped cripple some revenue gaps. Mobilities began to pick up again as producers had to deal with uneven regional recoveries, labour availability issues, and skyrocketing quality expectations allied with fast ramp-ups. Digital adoption got catalyzed through all that-remote PPAPs, virtual commissioning, predictive quality analytics-and gave regionalization strategies a push for strengthening resilience throughout casting, machining, heat treatment, and final inspection.

AUTOMOTIVE GEARS MARKET SEGMENTATION

By Type

Based on Type, the global market can be categorized into Spur Gear, Helical Gear, Bevel Gear, Worm Gear, Gear Rack, Others:

• Spur Gear: Spur gears are a highly common gear type in automotive applications, simple in design, robust, and efficient in transferring motion between parallel shafts. They are employed extensively in transmission systems, powertrains, and other subsidiary mechanisms and serve satisfactorily with relatively lower fabrication costs. Having this simple design with straight teeth ensures ease of manufacture and maintenance but can be noisier than other gears. Recent advances in material and surface treatment technologies have improved wear resistance and minimized vibrations and continue to allow spur gears to be considered a primary choice for cost-sensitive motor vehicle segments, especially passenger cars and light commercial vehicles.

• Helical Gear: Helical gears enjoy fame in the automotive world for their smooth functioning and quieter noise levels than spur gears, with the further advantage of bearing higher loads. Their obliquely cut teeth lengthen the time of bearing capacity of the load along the line of the teeth, thereby reducing stresses and minimizing sound generation during noise with the resulting high speed in the operation thereof, thus making them the choice in the current-day transmission. These gears bear wide uses in passenger cars and commercial vehicles where load is on the constraint for comfort, efficiency, and durability. This ultimately leads to an increased acceptance of helical gear designs. Gradual merging of the EV industry leads to compact designs with helical gears restoring power transfer levels efficiently. Material evolution and machining enhancements make it possible for these gears to handle ever-increasing densities of power.

• Bevel-Gear: Bevel gear has use in automotive powertrains to transfer torque between intersecting shafts: between the differential and axle shafts. They serve to regulate the power being distributed with respect to cornering smoothly and maintaining the vehicles' balance and efficiency. Being conical and having inclined teeth, bevel gear can handle torque precisely under varying loads. Engineering advances towards lightweight bevel designs with stronger alloys and better heat treatment processes. Bevel gears are currently being redesigned with the respect of quieter operation and service life as the vehicles are moving into electrification with enhanced performance requirements; thus ensuring their existence in the new generation of drivetrains.

• Worm Gear: Worm gears are used in automotive systems where high torque reduction and small size are desired, like steering mechanisms and auxiliary drive systems. Their peculiar screw design allows the production of a huge torque while the worm cannot be back-driven through the wheel, making it very much safety-conscious in certain critical vehicular operations. Traditional worm gear and wheel systems were the least efficient mechanisms because of the sliding contact. With advanced lubrication and materials, these effects can now be less pronounced so that modern worm gears are more efficient and suffer less wear. Those gears find their highest-level application in heavy-duty and engineering vehicles in so far as load-bearing capacity is concerned. Continuous innovation is maintaining the worm gear on the map despite competitors from other high-efficiency gear technologies.

• Gear Rack: Giving linear motion out of a rotating motion, gear racks are widely used in steering systems, making rack-and-pinion steering the dominant form of steering in modern-day passenger vehicles. Providing for accurate steering control, a compact design, and reliable performance, gear racks are considered an essential constituent in automotive safety and manoeuvrability. Newer manufacturing techniques are enabling the production of obsolete gear racks that are lighter yet stronger, thus supporting efficiency without compromising durability. With the growing adoption of electric power steering, the gear racks are being further refined for use with sensors and actuators for compatibility with advanced driver assistance systems. Improving steering response and dynamics of the vehicle thus continues to make it imperative amidst engineering.

• Others: In the automobile sector, other types of gears are also used, especially in areas such as planetary, hypoid, and custom applications of whatever large uses there are. Planetary gears are mainly considered in automatic and hybrid transmission as they provide compactness, maximum efficiency, and from torque transmission to smooth. Hypoid gears are widely used in rear-axle systems where the concern is to have it quietly running and at the same time operating under heavy-torque load. The scenario is, however, changing with custom-designed gears coming up fast for electric drivetrains, robotic assemblies, and autonomous vehicle platforms. These specialized solutions illustrate how focused the industry is on applying gear technologies to newer mobility paradigms, such as electrification, automation, and high-powered vehicle architectures.

By Application

Based on application, the global market can be categorized into Commercial Vehicles, Passenger Vehicles, Engineering Vehicles:

Strong gears are installed for trucks, buses, and heavy-duty fleets that go into their transmissions, differentials, and axles, resisting long working hours and high torque requirements. Maximum efficiency and reliability are imperative because any period of downtime spells heavy financial losses for owner-operators. Consequently, manufacturers are emphasizing stronger alloys, higher-precision machining, and improved heat treatments to keep these gears serviceable for longer periods with lesser intervals for maintenance. The advent of electrified commercial vehicles is also triggering the developments of gear systems that are quieter and lighter.

• Passenger Vehicle: The largest application segment for automotive gears is passenger vehicle gears, with consumer demand propelling this market into performance, comfort, and fuel economy areas. Gears in transmissions, steering gears, and auxiliary systems ensure that operations run smoothly and without much noise. With the birth of the automatic and dual-clutch transmissions, the complexity and accuracy of gear systems in passenger vehicles have increased manifolds. The ensuing electrification will also be modifying this segment with small gearsets for electric drivetrains, e-axles, and hybrid systems. Furthermore, digital manufacturing and simulation tools are shaping the future for quieter and more durable gear sets demanded by consumers who want a refined driving experience and reliable operation.

• Engineering Vehicles: The engineering vehicles such as construction equipment, mining trucks, and agricultural machinery rely on specialized gear systems to provide high torque and reliability under challenging working conditions. In particular, worm gears, bevel gears, and heavy-duty planetary gear systems have been applied in these vehicles to confront the challenges of uneven terrain, heavy loading, and continuous operation. Being a headache to design for, durability and ability to handle torque seem to stand ideally, while speed and noise level remain negligible concerns. Manufacturers are currently using advanced materials, surface coatings, and precision heat treatments to make their gears resilient to wear, dust, and shocks. With the rise of automation and smart machinery, the design of gears will continue to evolve to dovetail into advanced control schemes.
