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 primary functions and components of an idler pulley?

An idler pulley serves important functions in mechanical systems and consists of several key components. Let’s explore the primary functions and components of an idler pulley:

1. Primary Functions:

– Belt Guidance: The main function of an idler pulley is to guide the belt along a desired path, changing its direction as necessary. This ensures efficient power transmission and proper operation of the system.

– Tension Maintenance: Idler pulleys help maintain tension in the belt by taking up slack and preventing belt sagging or slippage. Proper tension is essential for optimal power transfer and system performance.

2. Components:

– Pulley Wheel: The pulley wheel is the circular component with a groove or V-shape that accepts the belt. It rotates on a fixed axle or bearing and provides a contact point for the belt to ride on.

– Axle or Bearing: The axle or bearing is the component that allows the pulley wheel to rotate smoothly. It provides support and reduces friction, ensuring efficient movement of the belt.

– Mounting Bracket: The mounting bracket is used to secure the idler pulley in its designated position within the system. It may be attached to a stationary structure or integrated into a movable mechanism.

– Tensioning Mechanism (Optional): In some cases, idler pulleys may incorporate a tensioning mechanism. This can include a spring-loaded arm or an adjustable bracket that allows for easy adjustment of belt tension.

– Housing or Guard (Optional): Depending on the application, an idler pulley may be enclosed within a housing or guarded to protect it from external elements and to prevent accidental contact with moving parts.

It’s important to select an idler pulley that is compatible with the specific belt type, system requirements, and load conditions. Proper installation and periodic maintenance, such as lubrication of bearings and inspection for wear, are essential to ensure smooth operation and extend the lifespan of the idler pulley.
