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 drive pulleys withstand extreme environmental conditions?
Drive pulleys are mechanical components used in various systems to transmit power and motion. They are commonly found in industries such as manufacturing, mining, and agriculture. The ability of drive pulleys to withstand extreme environmental conditions depends on several factors, including the materials used, the design and construction of the pulley, and the specific conditions it is exposed to.
In general, drive pulleys are designed to be durable and capable of operating under a wide range of environmental conditions. They are typically made from materials such as steel, cast iron, or aluminum, which offer good strength and resistance to wear and corrosion. These materials can withstand moderate to high temperatures, as well as exposure to moisture, dust, and other contaminants.
However, there are limits to the environmental conditions that drive pulleys can withstand. Extreme temperatures, such as those found in extremely hot or cold environments, can affect the performance and lifespan of the pulleys. High temperatures can cause thermal expansion, which may lead to misalignment or excessive wear. Cold temperatures can make materials more brittle and prone to cracking or breaking under stress.
In addition to temperature, other environmental factors such as humidity, corrosive substances, and abrasive particles can also impact the performance of drive pulleys. High humidity levels can promote corrosion, especially if the pulleys are not properly protected or coated with suitable protective finishes. Corrosion can weaken the pulley’s structural integrity and lead to premature failure.
Abrasive particles, such as dust or grit, can cause wear and tear on the pulley’s surface and the belt that runs on it. This can result in reduced traction and slipping, affecting the efficiency and reliability of the system. Proper maintenance and regular cleaning can help mitigate the effects of abrasive particles.
It’s worth noting that some applications may require special types of drive pulleys specifically designed to withstand extreme environmental conditions. For example, in industries where pulleys are exposed to chemicals or highly corrosive substances, pulleys made from stainless steel or other corrosion-resistant materials may be used.
In conclusion, while drive pulleys are designed to be robust and capable of withstanding a wide range of environmental conditions, there are limits to what they can endure. Extreme temperatures, humidity, corrosive substances, and abrasive particles can all impact the performance and lifespan of drive pulleys. It’s important to consider the specific environmental conditions and select pulleys that are suitable for the intended application.

What types of belts or cables are typically employed with drive pulleys?
Drive pulleys are commonly used in conjunction with various types of belts or cables to facilitate power transmission and motion control in mechanical systems. The choice of belt or cable depends on the specific application, load requirements, environmental conditions, and desired performance characteristics. Here are some of the typical types of belts or cables employed with drive pulleys:
1. V-Belts:
V-belts are a common type of belt used with drive pulleys. They have a trapezoidal cross-section that fits into the V-shaped groove of the pulley. V-belts are made of rubber or synthetic materials and are reinforced with cords or fibers to provide strength and flexibility. They are known for their high friction grip and are suitable for moderate power transmission applications. V-belts are widely used in industrial machinery, automotive engines, and other systems that require reliable power transmission.
2. Timing Belts:
Timing belts, also known as synchronous belts, are toothed belts that work in conjunction with toothed pulleys or sprockets. The teeth on the belt mesh with the grooves on the pulley, allowing for precise and synchronous power transmission. Timing belts are commonly made of rubber or polyurethane, reinforced with cords or fibers for strength. They are used in applications that require accurate positioning, such as in engines, robotics, and precision machinery.
3. Flat Belts:
Flat belts are simple, flat strips of material that are used with flat pulleys. They are usually made of rubber, leather, or fabric-reinforced materials. Flat belts offer flexibility and are suitable for applications that require high-speed power transmission. They are commonly used in light-duty machinery, such as printers, textile machines, and some conveyor systems.
