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 type of pulley that is used in mechanical systems to change the direction of a belt or to maintain tension in the belt. It is called an “idler” because it does not transmit power to any other components but instead acts as a guide or support for the belt.
The primary role of an idler pulley is to redirect the path of a belt in a system. It is typically used when the desired path of the belt requires a change in direction or when there is a need to take up slack or maintain proper tension in the belt.
Here are some key functions and roles of an idler pulley in mechanical systems:
1. Belt Direction Change:
An idler pulley can redirect the path of a belt, allowing it to travel around obstacles or change its course. By introducing an idler pulley at a specific location, the belt can be guided along a desired path, enabling efficient power transmission and operation of the system.
2. Belt Tension Maintenance:
Idler pulleys are often used to maintain proper tension in a belt. By incorporating an idler pulley in a belt system, it can take up slack or provide additional tension to ensure optimal power transmission and prevent belt slippage.
3. Belt Length Compensation:
In some systems, the length of the belt may need to be adjusted to accommodate variations in the distance between pulleys or to accommodate different operating conditions. Idler pulleys can be used to compensate for these variations by allowing the belt to be lengthened or shortened as required.
4. Belt Alignment:
Idler pulleys can contribute to maintaining proper belt alignment. By strategically positioning idler pulleys along the belt path, they can help guide the belt and prevent it from drifting or misaligning, ensuring smooth and efficient operation.
5. Noise and Vibration Reduction:
In some cases, idler pulleys can help reduce noise and vibration in a mechanical system. By properly tensioning the belt and minimizing unnecessary movement or oscillation, idler pulleys can contribute to a quieter and more stable operation.
It’s important to note that the specific role and function of an idler pulley can vary depending on the particular mechanical system and its requirements. Proper selection, installation, and maintenance of idler pulleys are crucial to ensure optimal performance, belt longevity, and overall system efficiency.
