Passenger Vehicles
Spiral bevel gears are primarily used in the drive axle systems of passenger vehicles, mainly serving the functions of power steering and torque amplification. With continuously increasing performance requirements, some drive units must transmit over 300kW of torque. Consequently, bevel gears must possess excellent transmission efficiency, smooth and quiet operation characteristics, and long-term maintenance-free performance. In industrial production, ensuring consistent machining quality and shortening production cycles have become core competitiveness indicators for manufacturers. ZDCY's integrated solutions ensure improvements in both quality and productivity.

Commercial Vehicles
In commercial vehicle drive systems, spiral bevel gears are core transmission components. Commercial vehicles generally use rear-wheel drive, and the bevel gear transmission devices need to transmit maximum torques as high as 550kW. This places high demands on the strength and service life of the gears. Bevel gears must simultaneously meet the requirements of high efficiency, high structural strength, and low maintenance characteristics. Using ZDCY's integrated solutions enables the large-scale precision production of such bevel gears.

Electric Vehicles (EVs)
High-precision involute cylindrical gears are key components in the transmission systems of electric vehicles. Compared with traditional fuel vehicles, the electric drive systems of EVs have higher requirements for gear precision and are more sensitive to noise. Therefore, high-performance machine tools are needed to manufacture gears for NEV transmission systems. ZDCY provides advanced cylindrical gear technology and solutions to meet the demands for high-precision, high-efficiency, and stable batch grinding of gears for high-end NEVs.

Construction Machinery
On construction machinery, spiral bevel gears are commonly used in drive systems. For example, they may be used in the travel drive systems of loaders, the track drive systems of excavators, and the lifting, slewing, and luffing mechanisms of cranes. Under heavy-duty conditions, spiral bevel gears should possess high load-carrying capacity, good operational smoothness, and durability. During power transmission, they should have high transmission efficiency to reduce the energy consumption and operating costs of construction machinery. Using ZDCY's integrated solutions allows for the batch production of such bevel gears that meet requirements.

Rail Transit
Spiral bevel gears are one of the important components in the transmission systems of subways and high-speed rail. Railway rolling stock requires high speed, high efficiency, low noise, and long service life. Consequently, spiral bevel gears need characteristics such as high transmission efficiency, low noise, and long life. ZDCY's spiral bevel gear integrated solutions can improve the operational efficiency and running smoothness of railway rolling stock while reducing energy consumption and maintenance costs.

Agricultural Machinery
In agricultural machinery transmission systems, both spiral bevel gears and straight bevel gears play important roles depending on different operating condition requirements. Spiral bevel gears are mainly applied in the rear axle drive systems of tractors, capable of carrying power transmission up to 400kW, and are also used for front axle transmission in 4WD models. In contrast, equipment like harvesters and hay balers often use straight bevel gears, which have a simpler structure, lower manufacturing cost, and are suitable for medium-to-low load transmission scenarios. ZDCY provides solutions that meet the modern production needs for both spiral and straight bevel gears.

Aerospace
Bevel gears used in the aerospace field must meet extremely stringent technical requirements. Their pitch accuracy and concentricity must achieve the highest grade standards (DIN 1-3), while ensuring absolute reliability of rotational motion. Additionally, tooth surface roughness must be strictly controlled, root geometry parameters optimized, rotational errors minimized, and high load-carrying capacity balanced with lightweight design. To meet these special requirements, high-performance special materials are usually required, placing very high standards on the selection of cutting tools and manufacturing processes. ZDCY provides optimal solutions for high-precision bevel gears used in aircraft.

Robotics
To achieve multi-degree-of-freedom motion, bevel gears are commonly used in the elbow and shoulder joints of robot arms. Bevel gears can change the direction of power transmission, converting the rotational motion of the motor into motion along axes different from the joint axis, thereby effectively adjusting the power transmission angle to help robots achieve flexible movement. Robot joints require bevel gears with high precision, low noise, and lightweight characteristics to ensure smooth motion and positioning accuracy. ZDCY's bevel gear solutions can produce ultra-precision small-module bevel gears for the robotics field.

Gear Reducers
In modern industrial machinery, gear reducers play a vital role as key transmission devices. Spiral bevel gears are widely used in gear reducers for right-angle power steering, high-load, and low-noise industrial scenarios, such as mining machinery and hoisting machinery. Bevel gears are also needed in reducers for medium and small torque mechanical equipment, such as industrial robots and automated equipment. For parallel shaft transmission requirements, a combined cylindrical gear structure is recommended. ZDCY's bevel gear and cylindrical gear solutions can meet customers' diverse needs.
