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°.

Ensure that maintenance personnel are trained in safe maintenance practices and are familiar with the specific procedures for working with belt pulleys.
8. Record Keeping: Maintain a record of maintenance activities and inspections performed on belt pulleys. This includes dates of inspections, lubrication, tension adjustments, belt replacements, and any corrective actions taken. Keeping a maintenance log helps track the history of maintenance activities, identify recurring issues, and plan future maintenance tasks effectively.
In summary, the maintenance requirements for belt pulleys in industrial settings include regular inspections, proper lubrication, tension adjustment, belt replacement, cleaning, alignment correction, adherence to safety measures, and maintaining a maintenance record. By following these maintenance requirements, industrial facilities can ensure the optimal performance, longevity, and safe operation of belt pulleys, contributing to the overall efficiency and reliability of their industrial processes.
What types of belts are commonly used with belt pulleys?
Several types of belts are commonly used in conjunction with belt pulleys for power transmission in various applications. The choice of belt depends on factors such as the specific requirements of the machinery, the desired power transmission characteristics, environmental conditions, and the type of pulley system being used. Here are some of the most commonly used types of belts:
1. V-Belts: V-belts, also known as Vee belts, are one of the most widely used types of belts with belt pulleys. They have a trapezoidal cross-section and typically feature a fabric cover and a rubber-like compound. V-belts are known for their high grip and power transmission capabilities, making them suitable for applications with moderate to high loads and speeds. They are commonly used in industries such as automotive, industrial machinery, and HVAC systems.
2. Timing Belts: Timing belts, also called synchronous belts, have toothed profiles on the inner side that engage with corresponding teeth on the pulley. This toothed design provides precise power transmission and prevents slippage. Timing belts are commonly used in applications that require precise synchronization of shafts and accurate positioning, such as in robotics, printing machinery, and automotive engines.
3. Flat Belts: Flat belts have a rectangular cross-section and are typically made of materials such as rubber, fabric, or synthetic compounds. They are flexible and can be easily customized to various lengths. Flat belts are commonly used in applications where high speeds and low power transmission requirements are present, such as in conveyor systems, textile machinery, and packaging equipment.
4. Round Belts: Round belts, also known as round O-ring belts, are circular belts made of materials such as rubber or urethane. They are flexible and can be easily joined to form endless loops. Round belts are commonly used in applications that require a lightweight and flexible power transmission solution, such as in small appliances, office equipment, and material handling systems.
5. Ribbed Belts: Ribbed belts, also called multi-rib belts or serpentine belts, have a ribbed or grooved design on the inner side. These ribs engage with corresponding grooves on the pulley, providing increased contact area and improved power transmission efficiency. Ribbed belts are commonly used in automotive engines, where they drive multiple accessories such as alternators, power steering pumps, and air conditioning compressors.
6. Variable Speed Belts: Variable speed belts, also known as adjustable speed belts or link belts, are made of individual links or segments that can be easily connected or disconnected to adjust the belt length. This allows for stepless speed variation and flexibility in power transmission. Variable speed belts are commonly used in applications where speed adjustment is required, such as in milling machines, woodworking equipment, and industrial conveyors.
These are just a few examples of the types of belts commonly used with belt pulleys. Each type of belt has its own unique characteristics and is suitable for specific applications based on factors such as load capacity, speed requirements, precision, and environmental conditions. The selection of the appropriate belt is crucial to ensure efficient and reliable power transmission in the machinery and equipment utilizing belt pulleys.
Can you explain the different types of belt pulleys and their applications?
There are several different types of belt pulleys, each designed for specific applications and requirements. The choice of pulley type depends on factors such as the power transmission needs, speed control requirements, space limitations, and the type of belt or rope used. Here’s an overview of some common types of belt pulleys and their applications:
1. V-Belt Pulleys: V-belt pulleys are one of the most widely used types of pulleys. They have a trapezoidal groove profile and are designed to accommodate V-belts, which have a corresponding cross-sectional shape. V-belt pulleys are commonly used in applications that require high torque transmission, such as in industrial machinery, automotive engines, and HVAC systems.
2. Flat Belt Pulleys: Flat belt pulleys have a flat or slightly crowned surface without any grooves. They are used with flat belts, which have a rectangular cross-section. Flat belt pulleys are suitable for applications that require high-speed power transmission, such as in textile machines, printing presses, and conveyor systems.
3. Timing Belt Pulleys: Timing belt pulleys, also known as synchronous pulleys, have teeth or grooves that mesh with the teeth of a timing belt. This design provides precise and synchronous power transmission, making them suitable for applications that require accurate positioning and timing, such as in robotics, CNC machines, and automotive engines.
4. Variable Speed Pulleys: Variable speed pulleys, also called adjustable or variable pitch pulleys, allow for continuous speed control by adjusting the effective diameter of the pulley. They feature movable pulley halves or arms that change the distance between the grooves, altering the speed ratio. Variable speed pulleys are used in applications where adjustable speed control is required, such as in machinery with variable loads or in variable speed drives.
5. Step Pulleys: Step pulleys have multiple grooves of different diameters arranged on the same pulley. By changing the belt position between these different grooves, the speed ratio can be adjusted. Step pulleys are commonly used in machines such as drill presses, lathes, and milling machines, where a range of predetermined speeds is required for different operations.
6. Idler Pulleys: Idler pulleys are not directly involved in power transmission but are used to redirect and tension the belt. They help maintain proper belt tension, improve belt wrap around the pulleys, and assist in achieving the desired belt path. Idler pulleys are commonly used in automotive engines, HVAC systems, and other belt-driven systems.
7. Clutch Pulleys: Clutch pulleys are specialized pulleys that incorporate a clutch mechanism. They allow for on-demand engagement and disengagement of the pulley from the driven shaft. Clutch pulleys are commonly used in automotive applications, such as in alternators, where they enable efficient power generation while reducing drag during idle or deceleration.
It’s important to note that these are just a few examples of belt pulley types, and there may be other specialized designs based on specific application requirements. The selection of the appropriate belt pulley type depends on factors such as the power transmission needs, speed control requirements, load capacity, and the type of belt or rope used.
