Metal conveyor belt pulleys are critical to the look of any automated conveyor belt program. They become the driving power behind the movement of the belt, creating torque and rate. In very general conditions it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision may be the name of the game with regards to pulleys. A steel belt is as good and exact as the pulleys. Most pulleys suggested by Ever-power are made of anodized aluminum (hard layer) with the proper friction coefficient to operate a vehicle the metal belt. Stainless steel may also be used nonetheless it is pricey and heavy, although it might end up being indicated using applications where extra hardness is essential. If your application requires a lighter pulley, the professionals at Ever-power can help you choose the best material.
Selecting the right pulley size and configuration can have a substantial influence on the lifespan and effectiveness of a conveyor belt. Ever-power engineers have the data and experience to assist you choose the appropriate pulley type, diameter, and composition to minimize maintenance downtime and increase product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom steel conveyor belt pulleys and configurations to bring maximum efficiency to your system. While metallic conveyor belts are usually made of stainless, pulleys can be created from a variety of materials, including aluminium or a number of plastic composites. According to the unique requirements of your system, the pulleys may also be installed with custom timing attachments, relief stations, 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 following 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 founded on the idea of changing tension human relationships over the width of the belt simply by adjusting the angle of the pulley relative to the belt.
Rather than 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 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, leading to controlled, bi-directional movement of the belt across the pulley face.
The ISP is exclusively available from Ever-power. It provides a simple approach to steering flat metal belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing elements to make a synergistic belt monitoring 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 designs minimize downtime when changing belts on production machinery.
· ISP system is easy to use and requires no special tools or schooling.
· ISP simplifies the design and assembly of conveyor systems using smooth belts.
· Existing idler pulleys can normally become retrofitted to an ISP without main system modifications.
· No maintenance is necessary once the belt tracking parameters have already been established.
· It prolongs belt existence by minimizing part loading when using flanges and timing pulleys.

Installation and Use
The ISP is mounted to the machine frame using commercially available pillow blocks. A clamp is utilized 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 can be a capped tube design.
· Is NEVER used when multiple pulleys are on a common shaft.
· Used selectively when the ISP is usually a steering roll in a multiple pulley system.
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 desired tracking characteristics are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will right now rotate about the bearing built into the ISP assembly. This method enables the belt to be tracked while working under tension.

This method enables the belt to end up being tracked while operating under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually adapt each belt/pulley combination when there are multiple pulleys on a common shaft.
· Utilized when systems have a cantilevered shafting typical of serpentine and various other complex belt path systems. It is suggested 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 required belt tracking characteristics are attained, 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 is certainly specified for a monitoring accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to establish a lateral constraint. The steering feature of the ISP is utilized to set one edge of the belt against the flange with minimal side-loading to the belt.
System Configuration
#2 2 – The drive pulley is a timing pulley.
· The ISP is certainly a friction driven pulley. The teeth of the drive pulley and the perforations of the belt establish a lateral constraint. The steering feature of the ISP is utilized to minimize side-loading of the belt perforations. Tracking precision is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metallic belt systems.
OR
· The ISP is certainly a timing pulley. The teeth of the ISP and the perforations of the belt are utilized for precise monitoring control of the belt with the steering feature of the ISP utilized to minimize part loading of belt perforations. Again, tracking precision is definitely 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Notice: Although it is normally not recommended to possess timing elements in both drive and driven pulleys, this style can be used selectively on metal belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the surface of the pulley consistently changes the tracking characteristic of the belt.
