Steel conveyor belt pulleys are critical to the design of any automated conveyor belt system. They act as the driving drive behind the motion of the belt, making torque and quickness. In very general terms it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the game when it comes to pulleys. A steel belt is only as good and exact as the pulleys. Most pulleys suggested by Ever-power are made from anodized aluminum (hard coat) with the right friction coefficient to operate a vehicle the steel belt. Stainless steel may also be used nonetheless it is costly and heavy, though it might end up being indicated using applications where extra hardness is essential. If your application requires a lighter pulley, the experts at Ever-power will help you choose the best material.
Selecting the correct pulley size and construction can have a substantial effect on the lifespan and performance of a conveyor belt. Ever-power engineers possess the data and experience to assist you choose the appropriate pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring maximum efficiency to your system. While metal conveyor belts are usually made of stainless, pulleys can be created from a number of materials, including aluminum or a variety of plastic composites. Depending on the unique requirements of one’s body, the pulleys may also be installed with customized timing attachments, relief stations, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in toned belt tracking called the ISP (independently steerable pulley), which can be utilized in the next system designs:
· Two pulley conveyor systems in which the ISP is the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or various other complex belt paths
Steering toned belts with an ISP is based on the idea of changing tension relationships over the width of the belt by adjusting the position of the pulley relative to the belt.
Instead of moving the pulley shaft still left/right or up/straight down by pillow prevent adjustment, the ISP fits a adjustable steering collar and sealed bearing assembly to the body of the pulley.
The steering collar was created with the skewed or an offset bore. When rotated, the collar changes the angle of the pulley body, resulting in controlled, bi-directional movement of the belt over the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple approach to steering flat metal belts. Users may combine ISP steering with the traditional belt tracking styles of crowning, flanging, and timing components to create a synergistic belt tracking system which effectively and specifically steers the belt to specified tracking parameters.
Unique Characteristics and Advantages of the ISP
· Flat belts are tracked quickly by rotating the steering collar.
· ISP styles minimize downtime when changing belts on creation machinery.
· ISP system is simple to use and needs simply no special tools or schooling.
· ISP simplifies the look and assembly of conveyor systems using flat belts.
· Existing idler pulleys may normally become retrofitted to an ISP without main system modifications.
· No maintenance is necessary once the belt monitoring parameters have already been established.
· It prolongs belt life by minimizing aspect loading when using flanges and timing pulleys.

Installation and Use
The ISP is mounted to the system frame using commercially available pillow blocks. A clamp can be used to avoid the shaft from turning.
The Rotated Shaft Method of ISP Flat Belt Tracking
· Is used in combination with systems having an individual pulley on the shaft.
· Is ALWAYS utilized when the pulley body is a capped tube style.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Utilized selectively when the ISP is definitely a steering roll in a multiple pulley system.
Secure the ISP to the shaft using the split training collar and locking screw built into the ISP. Rotate the shaft and collar as a unit. When the desired tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will now rotate about the bearing included in the ISP assembly. This technique enables the belt to be tracked while working under tension.
Secure the ISP to the shaft using the split collar and locking screw built into the ISP. Rotate the shaft and collar as a unit. When the desired tracking features are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will at this point rotate about the bearing built into the ISP assembly. This method enables the belt to end up being tracked while operating under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually change each belt/pulley combination when there are multiple pulleys on a common shaft.
· Used when systems possess a cantilevered shafting typical of serpentine and various other complex belt route systems. It is recommended that these adjustments be made only when the belt is at rest.
Fix the shaft via the shaft clamp, loosen the locking screw of the steering collar, and rotate the steering collar about the shaft. When the desired belt tracking features are attained, secure the locking screw.

System Configuration
Number 1 1 – The drive pulley is a friction drive pulley.
· The ISP is usually a friction-driven pulley. This configuration is definitely specified for a tracking accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are mounted on the pulley body to determine a lateral constraint. The steering feature of the ISP is used to set one advantage of the belt against the flange with reduced side-loading to the belt.
System Configuration
Number 2 2 – The drive pulley is a timing pulley.
· The ISP can be a friction driven pulley. The teeth of the drive pulley and the perforations of the belt set up a lateral constraint. The steering feature of the ISP can be used to minimize side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metal belt systems.
OR
· The ISP is certainly a timing pulley. The teeth of the ISP and the perforations of the belt are used for precise monitoring control of the belt with the steering feature of the ISP used to minimize part loading of belt perforations. Again, tracking precision can be 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Take note: Although it is normally not recommended to have timing elements in both drive and driven pulleys, this style can be utilized selectively on metal belt systems with lengthy center distances between pulleys and in applications where particulate accumulation on the top of pulley continuously changes the tracking feature of the belt.
