PRODUCT FEATURES

For pulleys with complex forces, large loads and used in heavy working conditions, they all adopt a cast welded structure and expansion sleeve connection. Compared with traditional drums in China, this type of drum mainly has the following characteristics :
(1) The structural parameters of the pulley are advanced and reasonable, and there is a dedicated computer calculation program to determine the shaft diameter, cylinder skin thickness, wheel amplitude plate shape and spacing, as well as the position of the circumferential weld seam set at the position where the stress is minimum and the number of cycles is minimum.
(2) The key technology of using single sided welding and double sided forming ensures the quality of the weld seam.
(3) The expansion sleeve connection is used between the drum hub and shaft, which not only solves the problem of key connection stress concentration that has been existing for many years and the technical difficulties of manufacturing and installing axial double keyways, but also achieves overall quenching and eliminates welding internal stress.

(4) The circumferential and longitudinal welds of the pulley have undergone non-destructive testing, and the casting quality of the wheel hub has undergone magnetic particle or ultrasonic testing.
(5) The total radial runout of the outer circle after roller casting is less than 1mm.
(6) All drums undergo static balance tests before leaving the factory to achieve G40 accuracy.
(7) All driving pulley and directional pulley with high stress have undergone finite element analysis to ensure that the stress and strain of the rollers meet the requirements.

Due to a series of measures taken, the pulley group produced by SK has a reasonable structure, large bearing capacity, and reliable performance. And it overcomes the problem of fatigue fracture at the welding seam of the existing pulley plate in China. The pullley (including the welding part) is guaranteed to have a rotational fatigue strength of over 108°.

What is the role of belt pulleys in the automotive industry?

Belt pulleys play a vital role in the automotive industry, contributing to various systems and components within vehicles. They are essential for transmitting power, driving auxiliary systems, and ensuring the smooth operation of critical functions. Here’s a detailed explanation of the role of belt pulleys in the automotive industry:

1. Engine Power Transmission: Belt pulleys are integral to the power transmission system of an automotive engine. They are commonly used in serpentine belt systems, where a single belt is routed around multiple pulleys to drive various engine accessories. The crankshaft pulley connects to the engine’s crankshaft and is responsible for transmitting power to components such as the alternator, water pump, power steering pump, and air conditioning compressor. The rotation of the crankshaft pulley drives the serpentine belt, which, in turn, drives these auxiliary systems.

2. Timing Belt System: Belt pulleys are essential components in the timing belt system of an engine. The timing belt connects the engine’s crankshaft to the camshaft(s), synchronizing their rotation and ensuring precise valve timing. The crankshaft pulley, also known as the harmonic balancer, is connected to the crankshaft and drives the timing belt. The camshaft pulleys, often referred to as timing pulleys, are responsible for driving the camshafts and controlling the opening and closing of the engine’s valves. Proper timing belt operation is crucial for the engine’s performance, efficiency, and overall reliability.

3. Supercharger and Turbocharger Systems: In high-performance and forced induction engines, belt pulleys are utilized in supercharger and turbocharger systems. These systems compress the intake air to increase engine power output. Belt-driven superchargers and turbochargers use pulleys to drive the compressor, which forces more air into the engine’s combustion chambers. The pulleys in these systems are designed to withstand high speeds and loads, ensuring efficient and reliable operation of the forced induction system.

4. Cooling System: Belt pulleys contribute to the cooling system of automotive engines. The water pump pulley is connected to the water pump, which circulates coolant throughout the engine to dissipate heat. The rotation of the water pump pulley, driven by the crankshaft pulley, creates the necessary flow of coolant to regulate engine temperature. Proper cooling system operation is vital for preventing overheating and maintaining the engine’s optimal operating conditions.

5. Power Steering System: Belt pulleys are used in power steering systems to assist with steering effort. The power steering pump pulley is connected to the power steering pump, which pressurizes hydraulic fluid to aid in turning the wheels. As the crankshaft pulley drives the serpentine belt, power is transmitted to the power steering pump pulley, enabling power-assisted steering. Belt-driven power steering systems provide easier and more responsive steering control for drivers.

6. Air Conditioning System: Belt pulleys play a role in the automotive air conditioning system. The air conditioning compressor pulley is driven by the serpentine belt and is responsible for compressing and circulating refrigerant within the system. The rotation of the compressor pulley enables the air conditioning system to cool and dehumidify the vehicle’s interior, providing comfort to occupants. Belt-driven air conditioning systems are commonly found in most passenger vehicles.

7. Other Auxiliary Systems: Belt pulleys are also used in other auxiliary systems in vehicles, such as the alternator, which generates electrical power to charge the battery and power electrical components. Additionally, they are employed in systems like the vacuum pump for brake assist, power take-off (PTO) units in commercial vehicles, and various belt-driven pumps for systems like the fuel injection system and hydraulic systems.

In summary, belt pulleys play a crucial role in the automotive industry, contributing to power transmission, auxiliary systems, and critical functions within vehicles. Whether it’s transmitting power in the engine, driving timing belts or auxiliary systems, or assisting with cooling, steering, or air conditioning, belt pulleys ensure the efficient and reliable operation of automotive systems and components.

How does the size and design of a belt pulley impact its performance?

The size and design of a belt pulley have a significant impact on its performance in power transmission systems. The size refers to the dimensions of the pulley, such as its diameter and width, while the design encompasses factors like the groove profile, material selection, and overall construction. Here’s a detailed explanation of how the size and design of a belt pulley impact its performance:

1. Speed and Power Transmission: The size of a belt pulley directly affects the speed and power transmission capability of the system. A larger pulley diameter results in higher belt speeds and increased power transmission capacity. On the other hand, a smaller pulley diameter allows for slower speeds and reduced power transmission. The selection of an appropriate pulley size depends on the desired speed and torque requirements of the application.

2. Belt Tension and Grip: The size and design of a belt pulley influence the tension and grip between the belt and pulley. A larger pulley diameter increases the angle of wrap, which improves the belt’s grip on the pulley and enhances power transmission efficiency. Additionally, the width of the pulley affects the contact area with the belt, allowing for higher load-carrying capacity. Proper belt tension and grip are crucial for preventing belt slippage, maximizing power transfer, and ensuring reliable operation.

3. Speed Ratio: The size and design of the driving and driven pulleys determine the speed ratio between them. By selecting pulleys of different sizes or varying the number of grooves, the speed ratio can be adjusted. This is important in applications where specific speed requirements need to be met, such as in machinery that requires different operating speeds for various operations. The design of the pulleys, including the groove profile and pitch diameter, must be considered to achieve the desired speed ratio.

4. Belt Life and Wear: The size and design of a belt pulley can impact the life and wear characteristics of the belt. Improper pulley sizing or design can lead to excessive belt tension, uneven belt loading, or misalignment, resulting in premature wear and failure of the belt. A well-designed pulley with appropriate dimensions, smooth groove profiles, and proper alignment reduces belt stress and wear, prolonging the belt’s lifespan and reducing maintenance requirements.

5. Noise and Vibration: The size and design of a belt pulley can influence the noise and vibration levels in the power transmission system. Proper pulley size selection and design considerations, such as balancing the pulley, ensuring concentricity, and minimizing runout, help reduce vibration and noise generation. This improves overall system performance, operator comfort, and reduces the potential for component fatigue or damage.

6. Material Selection and Construction: The design of a belt pulley includes material selection and construction considerations. Different materials, such as steel, cast iron, aluminum, or composites, offer varying levels of strength, durability, and resistance to factors like corrosion or extreme temperatures. The design may also include features like hubs, keyways, or flanges, which enhance the pulley’s performance and facilitate proper installation and alignment in the system.

Overall, the size and design of a belt pulley play a crucial role in determining its performance in power transmission systems. Factors such as speed and power transmission capability, belt tension and grip, speed ratio, belt life and wear, noise and vibration levels, and material selection all depend on the proper sizing and design of the pulley. Attention to these factors ensures optimal performance, efficiency, and reliability in belt-driven applications.
