PROCESS FLOW OF PULLEY
Our company is equipped with necessary equipment for processing pulleys, such as large oil pressure machines, rolling machines, specialized pulley automatic explosive welding operators, large diameter lathes, boring machines, ultrasonic flaw detectors, static balancing devices, pressure casting machines, etc. Due to the special correction process adopted by the company, the pulley pipe skin is rounded before processing, and the pulley pipe wall is uniform after processing, thereby ensuring that the pulley has high static balance performance and high mechanical performance.
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°.

V pulleys can be customized in terms of material selection. Different materials, such as cast iron, steel, aluminum, and plastic, offer varying levels of strength, durability, and corrosion resistance. The choice of pulley material depends on factors like the application environment, load capacity, and operating conditions. Customizing the pulley material ensures compatibility and optimal performance in specific machinery and equipment.
2. Pulley Dimensions:
The dimensions of V pulleys can be customized to match the requirements of machinery and equipment. This includes the diameter, width, and groove profile of the pulley.

Can V pulleys be integrated into conveyor systems for material handling?
Yes, V pulleys can be integrated into conveyor systems for material handling. Conveyor systems are widely used in various industries to transport materials efficiently and reliably. Here’s a detailed explanation of how V pulleys can be utilized in conveyor systems:
1. Belt Drive Mechanism:
V pulleys are commonly used as part of the belt drive mechanism in conveyor systems. The driving pulley is typically connected to a motor or an engine, while the driven pulley is connected to the conveyor belt. The rotation of the driving pulley causes the belt to move, enabling the transportation of materials along the conveyor.
2. Groove Profile:
V pulleys used in conveyor systems have a specific groove profile designed to match the shape of the V-belt used in the system. The groove angle, depth, and width are tailored to accommodate the corresponding V-belt dimensions. This ensures proper belt engagement and efficient power transmission, minimizing slippage and maximizing traction.
3. Belt Selection:
Various types of V-belts can be used in conveyor systems, depending on the specific requirements of the material handling application. Common V-belt types include classical V-belts, narrow V-belts, and cogged V-belts. The selection of the appropriate V-belt is based on factors such as load capacity, speed, environmental conditions, and the nature of the materials being conveyed.
4. Tensioning Mechanism:
V pulleys in conveyor systems are typically accompanied by a tensioning mechanism to maintain the proper tension in the belt. Tensioning devices such as idler pulleys or tensioners are used to adjust the tension and ensure optimal belt engagement with the pulleys. Proper tensioning is essential for efficient power transmission and to prevent belt slippage.
5. Pulley Diameter and Speed Ratio:
The diameter of the pulleys and the speed ratio between the driving and driven pulleys are critical considerations in conveyor system design. By selecting pulleys of different diameters, different speed ratios can be achieved, allowing for customization of the conveyor system’s speed and throughput. This flexibility enables the system to be tailored to the specific material handling requirements.
6. Belt Alignment and Tracking:
Proper alignment and tracking of the conveyor belt are essential for efficient operation and to prevent belt damage or premature wear. V pulleys are designed to facilitate belt alignment by providing a consistent and stable contact surface for the belt. Additionally, tracking devices such as aligning idlers or belt tracking systems can be incorporated to ensure the belt stays centered on the pulleys.
7. Durability and Maintenance:
V pulleys used in conveyor systems are typically made of durable materials such as steel or cast iron, which can withstand the demands of continuous operation and heavy loads. Regular maintenance, including inspection, lubrication, and occasional belt replacement, is necessary to ensure the long-term efficiency and reliability of the conveyor system.
Overall, V pulleys are an integral component of conveyor systems for material handling. Their design characteristics, combined with the use of appropriate V-belts and proper tensioning, facilitate efficient power transmission, reliable operation, and effective transport of materials in various industrial applications.
