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 an idler pulley, and what is its role in mechanical systems?
An idler pulley is a specific type of pulley that is used in mechanical systems. Here’s a detailed explanation of what an idler pulley is and its role in mechanical systems:
Definition:
An idler pulley is a pulley that is not directly connected to a power source or used for power transmission. Instead, it is used to guide and redirect a belt or rope in a system. The idler pulley is typically positioned in such a way that it changes the direction of the belt or rope, adjusts tension, or provides support to ensure smooth operation.
Role in Mechanical Systems:
The primary role of an idler pulley in mechanical systems is to maintain proper tension and alignment of belts or ropes. It helps to redirect the path of the belt or rope, ensuring that it remains in the correct position and stays engaged with other pulleys or components.
Here are some specific roles and functions of idler pulleys:
1. Belt Tension:
An idler pulley can be used to adjust and maintain the tension in a belt or rope. By adding or removing an idler pulley or adjusting its position, the tension in the belt can be properly controlled. This is crucial for preventing slippage, ensuring efficient power transmission, and extending the lifespan of the belt.
2. Directional Change:
In some systems, an idler pulley is strategically placed to change the direction of the belt or rope. By guiding the belt along a different path, the idler pulley allows the belt to reach components that would otherwise be inaccessible or difficult to connect directly. This enables flexibility in designing mechanical systems and facilitates the proper functioning of various components.
3. Belt Alignment:
An idler pulley helps maintain proper alignment of belts or ropes. It ensures that the belt remains centered on the pulleys and does not deviate from its intended path. Proper alignment is vital for efficient power transmission, as misaligned belts can cause increased friction, wear, and loss of energy.
4. Load Distribution:
In systems with multiple belts or ropes, an idler pulley can be used to distribute the load evenly. By introducing an idler pulley between two driving pulleys, the load can be divided, reducing stress on individual components and improving overall system performance.
5. Noise and Vibration Reduction:
