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°.

What is the significance of proper alignment and tensioning in drive pulley systems?
Proper alignment and tensioning are critical factors in the performance and longevity of drive pulley systems. They play a significant role in ensuring efficient power transmission, reducing wear and tear, and preventing premature failures. Here’s a detailed explanation of the significance of proper alignment and tensioning:
Alignment:
Proper alignment refers to the correct positioning of the drive pulleys in relation to each other and other system components, such as belts, shafts, and bearings. It is crucial for the following reasons:
- Efficient Power Transmission: Misaligned pulleys can cause the belts to run at an angle, resulting in increased friction and energy loss. This inefficiency can lead to reduced power transmission and decreased overall system performance.
- Reduced Wear and Tear: Misalignment puts excessive stress on the belts, pulleys, and other components. This can lead to accelerated wear and tear, resulting in increased maintenance and replacement costs. Proper alignment helps distribute the load evenly, minimizing stress and extending the lifespan of the components.
- Prevention of Belt Slippage: Misalignment can cause belts to slip or derail from the pulleys, leading to a loss of power transmission and potential damage to the belts. Proper alignment ensures that the belts remain securely engaged with the pulleys, preventing slippage and maintaining reliable operation.
- Optimal Belt Tracking: Correct pulley alignment helps maintain proper belt tracking, ensuring that the belts stay centered on the pulleys and run smoothly. This prevents the belts from rubbing against the pulley edges or adjacent components, reducing friction and minimizing the risk of belt damage.
Tensioning:
Proper tensioning refers to the appropriate adjustment of belt tension in drive pulley systems. It is crucial for the following reasons:
- Optimal Power Transmission: Adequate belt tension is necessary for efficient power transmission. Insufficient tension can result in belt slippage, reducing the transfer of power from the drive pulley to the driven pulley. On the other hand, excessive tension can overload the system, leading to increased wear and power losses.
- Maintaining Belt Grip: Proper tensioning ensures that the belts maintain sufficient grip on the pulleys, especially when transmitting high torque or operating under heavy loads. This prevents belt slippage and ensures reliable power transfer.
- Prevention of Belt Damage: Improper tensioning can cause excessive stress on the belts, leading to stretching, cracking, or premature failure. By maintaining the correct tension, the risk of belt damage is minimized, resulting in longer belt life and reduced downtime.
- Reduced Noise and Vibration: Inadequate tensioning can cause belts to vibrate or produce noise during operation. Proper tensioning helps dampen vibrations, resulting in smoother and quieter system performance.
Overall, proper alignment and tensioning are essential for optimizing the performance, reliability, and longevity of drive pulley systems. They contribute to efficient power transmission, reduced wear and tear, prevention of belt slippage, and minimized maintenance costs. Regular inspection and adjustments should be performed to ensure that the drive pulley system remains properly aligned and tensioned throughout its operation.
