Metal pulley

Steel conveyor belt pulleys are critical to the design of any automated conveyor belt program. They act as the driving power behind the movement of the belt, creating torque and quickness. In very general conditions 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 metal belt is only as good and specific as the pulleys. Many pulleys recommended by Ever-power are made of anodized aluminum (hard coating) with the proper friction coefficient to operate a vehicle the metal belt. Stainless steel can also be used but it is costly and heavy, though it might end up being indicated in certain applications where extra hardness is necessary. If your application requires a lighter pulley, the experts at Ever-power will help you select the best material.
Selecting the right 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 correct pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring maximum efficiency to your system. While steel conveyor belts are typically made of stainless steel, pulleys can be created from a variety of materials, including aluminium or a variety of plastic composites. Depending on the unique requirements of one's body, the pulleys can also be installed with customized timing attachments, relief channels, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in flat 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 other complex belt paths
Steering toned belts with an ISP is based on the concept of changing tension interactions across the width of the belt simply by adjusting the position of the pulley in accordance with the belt.
Instead of moving the pulley shaft still left/right or up/down by pillow prevent adjustment, the ISP fits a adjustable steering collar and sealed bearing assembly to your 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, leading to controlled, bi-directional movement of the belt across the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple approach to steering flat metallic belts. Users may combine ISP steering with the traditional belt tracking designs of crowning, flanging, and timing elements to create a synergistic belt tracking system which efficiently and specifically steers the belt to specified tracking parameters.
Unique Characteristics and Benefits of the ISP
· Toned belts are tracked quickly by rotating the steering collar.
· ISP styles minimize downtime when replacing belts on production machinery.
· ISP system is easy to use and requires simply no special tools or schooling.
· ISP simplifies the look and assembly of conveyor systems using smooth belts.
· Existing idler pulleys can normally be retrofitted to an ISP without main system modifications.
· No maintenance is required once the belt tracking parameters have already been established.
· It prolongs belt lifestyle by minimizing side 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 prevent the shaft from turning.
The Rotated Shaft Approach to ISP Flat Belt Tracking
· Is used in combination with systems having a single pulley on the shaft.
· Is ALWAYS utilized when the pulley body is usually a capped tube design.
· Is NEVER used when multiple pulleys are on a common shaft.
· Utilized selectively when the ISP is a steering roll in a multiple pulley system.
Secure the ISP to the shaft using the split training collar and locking screw included in the ISP. Rotate the shaft and collar as a device. When the desired tracking features are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will today rotate about the bearing included in the ISP assembly. This method allows the belt to end up being tracked while operating under tension.
Protected the ISP to the shaft using the split collar and locking screw built into the ISP. Rotate the shaft and collar as a device. When the required tracking characteristics 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 technique allows the belt to become tracked while operating under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually modify each belt/pulley combination when there are multiple pulleys on a common shaft.
· Used when systems have a cantilevered shafting typical of serpentine and other complex belt path systems. It is recommended that these modifications be made only once the belt reaches 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 required belt tracking characteristics are obtained, secure the locking screw.

System Configuration
#1 1 - The drive pulley is a friction drive pulley.
· The ISP is a friction-driven pulley. This configuration can be specified for a tracking accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are mounted on the pulley body to establish a lateral constraint. The steering feature of the ISP can be used to set one advantage of the belt against the flange with reduced side-loading to the belt.
System Configuration
#2 2 - The drive pulley is a timing pulley.
· The ISP is a friction driven pulley. One's teeth of the drive pulley and the perforations of the belt set up a lateral constraint. The steering feature of the ISP is used to reduce side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metallic belt systems.
OR
· The ISP can be a timing pulley. One's teeth of the ISP and the perforations of the belt are utilized for precise tracking control of the belt with the steering feature of the ISP utilized to minimize part loading of belt perforations. Again, tracking accuracy is 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 the drive and driven pulleys, this design can be utilized selectively on steel belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the top of pulley constantly changes the tracking feature of the belt.
