Working Principle
Single reduction gear is a driving bevel gear (commonly known as angular gear) and a basin angle gear pair. The driving bevel gear is connected with the transmission shaft, rotates clockwise, sticks to its right side from the bevel gear, and rotates downward at the meshing point, which is consistent with the CHINAMFG direction of the wheel. Due to the small diameter of the driving bevel gear and the large diameter of the bevel gear, the function of deceleration is achieved.
The double reduction has an additional intermediate transition gear.The left side of the driving bevel gear is meshed with the bevel gear of the intermediate gear. The bevel gear is coaxial with a spur gear with small diameter, and the spur gear is meshed with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There is a two-stage deceleration process in the middle.
Due to the increase of axle volume, double reduction was mainly used in vehicles with low engine power in the past, mainly in construction machinery with low speed and high torque.
In the double reduction final drive, if the second-stage deceleration is carried out near the wheel, it actually constitutes an independent part at the 2 wheels, it is called wheel reducer. The advantage of this is that the torque transmitted by the half shaft can be reduced, which is conducive to reducing the size and quality of the half shaft. The wheel reducer can be planetary gear type or composed of a pair of cylindrical gear pairs. When the cylindrical gear pair is used for wheel side deceleration, the up-down position relationship between the wheel axis and the half shaft can be changed by adjusting the mutual position of the 2 gears. This kind of axle is called portal axle, which is often used for vehicles with special requirements for the high and low position of the axle.
According to the number of the main reducer transmission ratio, it can be divided into single-speed and double-speed.
Domestic cars basically adopt single speed main reducer with fixed transmission ratio. On the double reduction final drive, there are 2 transmission ratios for selection, and this main reducer actually acts as an auxiliary transmission.

How do spiral gears handle changes in direction and torque transmission?
Spiral gears are well-suited to handle changes in direction and torque transmission due to their unique design and characteristics. Here’s how spiral gears handle these aspects:
- Smooth Direction Changes: Spiral gears excel at transmitting power smoothly even during changes in direction. The helical tooth arrangement allows for gradual tooth engagement and disengagement as the gears rotate. This gradual engagement minimizes the impact and shock typically associated with sudden direction changes in gear systems. As a result, spiral gears provide smoother and more reliable power transmission during both forward and reverse rotations.
- Torque Transmission: Spiral gears are capable of transmitting high torque loads. The helical tooth profile and increased tooth contact area allow for efficient torque transfer between the driving and driven gears. The load distribution across multiple teeth helps to minimize stress concentration and maximize the gear’s torque-carrying capacity. This makes spiral gears suitable for applications requiring high torque transmission, such as heavy machinery and industrial equipment.
- Axial Thrust Compensation: Spiral gears can be designed with opposite helix angles on mating gears, resulting in axial thrust cancellation. This feature is particularly beneficial when dealing with bidirectional torque transmission. By canceling out the axial thrust, spiral gears can operate with reduced axial forces, ensuring smoother gear operation and minimizing the need for additional thrust bearings or complicated gear arrangements.
- Load Sharing: Spiral gears naturally distribute the load across multiple teeth due to their helical tooth arrangement. This load sharing capability helps to minimize tooth wear and fatigue, ensuring long-term durability and reliability, especially when subjected to varying torque conditions. By distributing the load, spiral gears can handle torque variations more effectively and maintain uniform tooth contact, resulting in improved performance and extended gear life.
These characteristics of spiral gears—smooth direction changes, efficient torque transmission, axial thrust compensation, and load sharing—make them highly suitable for applications that require reliable and precise power transmission in both directions. Spiral gears are commonly used in various industries, including automotive, aerospace, and heavy machinery, where the ability to handle changes in direction and torque is crucial.
What are the limitations of using spiral gears in certain applications?
While spiral gears offer numerous advantages, they also have certain limitations that need to be considered when selecting them for specific applications. Here are some limitations of using spiral gears:
- Axial Thrust: Spiral gears generate axial thrust due to their helical tooth arrangement. This axial thrust can impose additional forces on the gear shafts and bearings, requiring proper design considerations and potential incorporation of thrust bearings in certain applications. Managing and compensating for axial thrust is crucial to ensure smooth gear operation.
- Manufacturing Complexity: The manufacturing process for spiral gears involves more complexity compared to straight-toothed gears. The helical tooth profile requires specialized cutting tools and machining techniques, adding to the manufacturing cost and complexity. This complexity may limit their use in applications with strict cost constraints or where simplicity of manufacturing is a priority.
- Axial Space Requirement: Spiral gears require more axial space compared to parallel-axis gears. The helical tooth profile results in a longer gear face width, which can limit their use in applications with space constraints. It is important to ensure that sufficient axial space is available to accommodate the larger size of spiral gears.
- Gear Alignment: Proper gear alignment is critical for spiral gears to function optimally. Any misalignment between the driving and driven gears can result in increased noise, vibration, and premature wear. Achieving and maintaining precise gear alignment may require additional attention and care during installation and regular maintenance.
- Speed Limitations: Spiral gears may have certain speed limitations due to the potential for tooth deflection and increased heat generation. At high speeds, the centrifugal forces acting on the helical teeth can cause deflection, leading to reduced gear accuracy and increased noise. Additionally, the sliding contact between the teeth can result in higher heat generation, requiring appropriate lubrication and cooling measures in high-speed applications.
While these limitations exist, they can often be managed or mitigated through proper design, engineering, and maintenance practices. It is important to carefully evaluate the specific requirements and constraints of the application to determine whether spiral gears are suitable or if alternative gear types may be more appropriate.
What are spiral gears and how are they used in machinery?
Spiral gears are a type of cylindrical gears with teeth that are curved in a spiral pattern. Unlike straight-cut gears, which have teeth that are parallel to the gear axis, spiral gears have teeth that are angled or helical. This helical tooth arrangement provides several advantages in terms of performance and noise reduction.
Spiral gears are commonly used in machinery for various applications due to the following reasons:
- Smooth and Quiet Operation: The helical tooth arrangement of spiral gears enables gradual tooth engagement, resulting in smoother and quieter operation compared to straight-cut gears. The angled teeth allow for gradual contact, reducing noise and vibration during gear meshing.
- Increased Load Capacity: The helical tooth design of spiral gears distributes the load over multiple teeth, increasing the load-carrying capacity. This makes spiral gears suitable for applications that require high torque transmission and heavy-duty operations.
- Improved Efficiency: The helical tooth arrangement of spiral gears helps in minimizing sliding friction between the teeth. This results in a higher level of efficiency compared to straight-cut gears, as there is reduced power loss due to friction during gear operation.
- Axial Thrust Compensation: Spiral gears can be designed with opposite helix angles on mating gears, which helps in canceling out the axial thrust generated during gear meshing. This feature eliminates the need for additional thrust bearings, simplifying the gear design and reducing complexity.
- Versatility: Spiral gears can be manufactured in various configurations, including spur, helical, and double helical designs. This versatility allows for their application in a wide range of machinery, including automotive systems, industrial equipment, and power transmission systems.
In machinery, spiral gears are commonly used in applications that require smooth operation, high load capacity, and efficient power transmission. Some examples include gearboxes, automotive differentials, machine tools, and heavy-duty industrial machinery.
Overall, the unique tooth geometry of spiral gears makes them a preferred choice in many machinery applications, offering improved performance, reduced noise, and enhanced load-carrying capabilities.
