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 the difference between a fixed and a swivel pulley?
Fixed and swivel pulleys are two common types of pulleys that differ in their design and functionality. Here are the key differences between these two types:
1. Fixed Pulley: A fixed pulley is a type of pulley that is mounted or attached to a fixed point, such as a beam or a ceiling. It does not move or rotate independently of its mounting point. The primary function of a fixed pulley is to change the direction of the force applied to a rope or cable. When a force is applied to the rope or cable passing through a fixed pulley, the load moves in the opposite direction. However, a fixed pulley does not provide any mechanical advantage, meaning it does not reduce the effort required to lift the load.
2. Swivel Pulley: A swivel pulley, also known as a movable pulley, is designed to rotate or swivel on a separate mounting point. It has a built-in mechanism that allows it to move independently. Unlike a fixed pulley, a swivel pulley is capable of changing both the direction and the magnitude of the force applied to the rope or cable. When a force is applied to the rope or cable passing through a swivel pulley, the load moves in the same direction as the applied force. Additionally, a swivel pulley provides a mechanical advantage by distributing the load's weight over multiple strands of rope or cable, reducing the effort required to lift the load.
In summary, the main differences between fixed and swivel pulleys are:
– Fixed pulleys are stationary and do not move independently, while swivel pulleys can rotate or swivel on a separate mounting point.
– Fixed pulleys change the direction of the force applied to the rope or cable, while swivel pulleys change both the direction and the magnitude of the force.
– Fixed pulleys do not provide a mechanical advantage, while swivel pulleys provide a mechanical advantage by distributing the load's weight over multiple strands of rope or cable.
Both fixed and swivel pulleys have their specific applications and can be used individually or in combination with each other to achieve desired mechanical functions in various systems and setups.
How do pulleys contribute to the functioning of bicycles and motorcycles?
Pulleys play important roles in the functioning of both bicycles and motorcycles, aiding in power transmission, speed control, and overall mechanical efficiency. Here's how pulleys contribute to the operation of these vehicles:
1. Bicycles:
– Derailleur System: In most modern bicycles, pulleys are used in the derailleur system. The derailleur is responsible for shifting the bicycle chain between different gears on the front and rear sprockets. Pulleys, often referred to as jockey wheels, are positioned in the derailleur to guide and tension the chain as it moves between gears. They ensure smooth and precise shifting, allowing the rider to adapt to various terrains and maintain an optimal pedaling cadence.
– Belt Drive Systems: Some bicycles use a belt drive instead of a traditional chain drive. Belt drives employ a pulley system that consists of a front pulley attached to the pedal crank and a rear pulley attached to the rear wheel hub. The belt is wrapped around these pulleys, transferring power from the rider's pedaling motion to propel the bicycle forward. Pulleys in belt drive systems enable efficient power transfer, reduce maintenance needs, and provide a quieter and cleaner alternative to chain drives.
2. Motorcycles:
– Clutch System: Pulleys, known as clutch pulleys, are utilized in motorcycle clutch systems. The clutch connects the engine to the transmission and allows the rider to engage or disengage power transmission to the rear wheel. When the clutch lever is pulled, the clutch pulley separates the engine's rotational motion from the transmission, disengaging power transfer. Releasing the clutch lever brings the pulley back into contact, engaging power transmission and enabling the motorcycle to move.
– Variable Transmission Systems: Some motorcycles employ pulleys in variable transmission systems, such as continuously variable transmissions (CVT). CVTs use a pair of pulleys connected by a belt or chain. By changing the diameter of the pulleys, the CVT adjusts the gear ratio continuously, providing seamless and efficient power delivery across a wide range of speeds. Pulleys in variable transmission systems contribute to smooth acceleration, improved fuel efficiency, and enhanced riding comfort.
– Drive Belt Systems: Pulleys are also utilized in motorcycles equipped with belt drive systems. Similar to bicycles, these systems consist of a front pulley connected to the engine's crankshaft and a rear pulley connected to the rear wheel. The belt runs around these pulleys, transferring power from the engine to the rear wheel. Belt drive systems offer advantages such as reduced maintenance, quieter operation, and smoother power delivery compared to traditional chain drives.
Overall, pulleys are integral components in bicycles and motorcycles, contributing to smooth gear shifting, efficient power transmission, and improved overall performance. Whether in derailleur systems, belt drive systems, clutch systems, or variable transmission systems, pulleys play a vital role in enhancing the functionality and ride experience of these vehicles.
Wat binne de foardielen fan it brûken fan pulleys foar meganyske foardiel?
It brûken fan pulleys foar meganyske foardiel biedt ferskate foardielen yn ferskate tapassingen. Hjir binne de wichtichste foardielen:
1. Ferhege Lifting Kapasiteit: Ien fan 'e primêre foardielen fan it brûken fan pulleys foar meganyske foardiel is dat se tastean foar it opheffen fan swierdere loads mei minder ynspanning. Troch it fersprieden fan de lading oer meardere segminten fan tou of riem, pulleys ferminderje it bedrach fan de krêft nedich te heffen de lading. Dit is foaral foardielich yn senario's wêrby't hânmjittich opheffen of beheinde krêft belutsen is.
2. Makliker Load Manipulation: Pulleys meitsje it makliker om te manipulearjen en kontrôle swiere loads. De meganyske foardiel fan pulleys ferminderet de krêft dy't nedich is om de lading te ferpleatsen of op te heffen, wêrtroch operators minder ynspannings kinne oefenje. Dit makket taken lykas it opheffen, ferleegjen en pleatsen fan swiere objekten handterberder en minder fysyk easken.
3. Feiligens en blessuereprevinsje: Troch it ferminderjen fan de hoemannichte krêft dy't nedich is om swiere loads op te heffen, drage pulleys by oan ferbettere feiligens en blessuereprevinsje. As operators minder fysike ynspanning moatte oefenje, wurdt it risiko fan spanningen, ferstuikingen en oare blessueres dy't relatearre binne oan opheffen signifikant fermindere. Pulleys kinne kontrolearre en soepeler ladingbeweging mooglik meitsje, it risiko fan hommelse ferskowingen of drippen minimalisearje dy't ûngemakken kinne feroarsaakje.
4. Precise Load Positioning: Pulley systemen jouwe sekuere kontrôle oer lading posysjonearring. Troch meardere pulleys te brûken en de spanning yn 'e tou of riem oan te passen, kinne operators krekte fertikale en horizontale bewegingen fan' e lading berikke. Dit nivo fan kontrôle is benammen weardefol yn tapassingen dy't krekte pleatsing fan swiere objekten fereaskje, lykas konstruksje, fabrikaazje en materiaalôfhanneling.
5. Veelzijdigheid en oanpassingsfermogen: Pulleys biede veelzijdigheid en oanpassingsfermogen yn ferskate applikaasjes. Se kinne wurde konfigurearre yn ferskate arranzjeminten en kombinaasjes te berikken spesifike meganyske foardielen basearre op de easken fan de taak of lading. Pulleys kinne maklik wurde yntegrearre yn besteande systemen of opnaam yn oanpaste-ûntwurpen opset, wêrtroch't se tige oanpasber oan ferskate situaasjes.
6. Effisjinte Power Transmission: Pulleys jouwe effisjinte macht oerdracht yn meganyske systemen. Se meitsje de oerdracht fan rotaasjebeweging en krêft fan de iene komponint nei de oare mooglik mei minimaal enerzjyferlies. It brûken fan pulleys makket it mooglik om te optimalisearjen fan macht oerdracht, en soarget foar effektyf benutten fan beskikbere macht boarnen.
7. Kosten-effektiviteit: It brûken fan pulleys foar meganyske foardiel kin kosten-effektyf wêze yn ferliking mei alternative metoaden. Pulleys binne relatyf ienfâldige en ekonomyske apparaten dy't maklik kinne wurde krigen. Se fereaskje minimaal ûnderhâld en hawwe in lange operasjonele libbensdoer. Derneist kinne pulleysystemen faak wurde ûntwurpen en ymplementearre sûnder de needsaak foar komplekse en djoere apparatuer.
Ta beslút, it brûken fan pulleys foar meganyske foardiel biedt foardielen lykas ferhege opheffen kapasiteit, makliker load manipulaasje, feiligens en blessuere previnsje, sekuere lading posysjonearring, veelzijdigheid, effisjinte macht oerdracht, en kosten-effektiviteit. Dizze foardielen meitsje pulleys in weardefol ark yn in breed skala oan yndustry en tapassingen.
