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°.

Can you explain the basic principles of pulley mechanics?

Pulley mechanics are based on a few fundamental principles that govern the operation of pulley systems. Here's an explanation of the basic principles:

1. Mechanical Advantage: The primary principle of pulley mechanics is mechanical advantage. A pulley system allows for the multiplication of force applied to the rope or belt. By distributing the force over multiple segments of the rope or belt, the load becomes easier to lift or move. The mechanical advantage gained depends on the number of pulleys used in the system. The more pulleys in the system, the greater the mechanical advantage.

2. Force Transmission: When a force is applied to one end of the rope or belt, it creates tension that causes the pulley to rotate. As the pulley turns, the force is transmitted to the load attached to the other end of the rope or belt. This force transmission allows for the movement and manipulation of objects in pulley systems.

3. Directional Change: One of the key principles of pulley mechanics is directional change. A pulley system enables the operator to change the direction of the applied force. By redirecting the force along a different path, a pulley system allows for force to be exerted from a more convenient or advantageous position. This directional change is particularly useful in situations where the force needs to be applied vertically, horizontally, or at an angle.

4. Conservation of Energy: Pulley mechanics also adhere to the principle of conservation of energy. The work done on the load by the applied force is equal to the work done against the load's weight. Through the pulley system, the input force is transformed into an output force that moves or lifts the load. The energy input and output remain the same, but the pulley system allows for the distribution and transformation of forces to achieve the desired mechanical advantage.

5. Speed and Torque Conversion: Pulleys can also be used to convert speed and torque in mechanical systems. By varying the size of the pulleys or using pulleys of different diameters, the rotational speed and torque can be adjusted according to the requirements of the system. This speed and torque conversion allows for the optimization of power transmission and the matching of different rotational speeds between input and output components.

6. Multiple Pulley Systems: Pulleys can be combined in systems to achieve increased mechanical advantage or to create complex motion patterns. In systems with multiple pulleys, such as block and tackle arrangements, the load is distributed over several segments of rope or belt, further reducing the effort required to lift heavy objects. These systems are often used in cranes, elevators, and other applications where heavy lifting is necessary.

These basic principles of pulley mechanics form the foundation for the understanding and application of pulleys in mechanical systems. By harnessing mechanical advantage, force transmission, directional change, conservation of energy, and speed/torque conversion, pulley systems provide a versatile means of lifting, moving, and manipulating loads in various applications.
