Metal pulley

Metal conveyor belt pulleys are critical to the design of any automated conveyor belt system. They become the driving drive behind the movement of the belt, generating torque and speed. In very general conditions it can be stated that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision may be the name of the overall game when it comes to pulleys. A metal belt is only as good and exact as the pulleys. The majority of pulleys suggested by Ever-power are made from anodized aluminum (hard coating) with the right friction coefficient to drive the metal belt. Stainless steel may also be used but it is costly and heavy, although it might become indicated using applications where extra hardness is necessary. If your application takes a lighter pulley, the specialists 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 possess the data and experience to assist you choose the right pulley type, diameter, and composition to minimize maintenance downtime and maximize product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom metal conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While metal conveyor belts are usually made of stainless steel, pulleys can be produced from a number of materials, including aluminium or a number of plastic composites. Based on the unique requirements of one’s body, the pulleys can also be installed with custom timing attachments, relief channels, and more.
Independently Steerable Pulley
Ever-power has developed an innovative concept in smooth belt tracking called the ISP (independently steerable pulley), which can be used 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 smooth belts with an ISP is based on the idea of changing tension associations over the width of the belt by adjusting the angle of the pulley relative to the belt.
Rather than 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 your body of the pulley.
The steering collar was created with the skewed or an offset bore. When rotated, the collar changes the position of the pulley body, resulting in 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 steel belts. Users may combine ISP steering with the original belt tracking designs 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 Benefits of the ISP
· Toned belts are tracked quickly by rotating the steering collar.
· ISP designs minimize downtime when replacing belts on creation machinery.
· ISP system is simple to use and needs no special tools or schooling.
· ISP simplifies the design and assembly of conveyor systems using smooth 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 been established.
· It prolongs belt lifestyle by minimizing aspect loading when working with flanges and timing pulleys.

Installation and Use
The ISP is mounted to the system frame using commercially available pillow blocks. A clamp is used to prevent the shaft from turning.
The Rotated Shaft Approach to ISP Flat Belt Tracking
· Is used with systems having a single pulley on the shaft.
· Is ALWAYS used when the pulley body is usually a capped tube style.
· Is NEVER used when multiple pulleys are on a common shaft.
· Used selectively when the ISP is a steering roll in a multiple pulley system.
Protected 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 required tracking characteristics are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will today rotate about the bearing built into the ISP assembly. This technique allows the belt to be tracked while running under tension.
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 required tracking features are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will now rotate about the bearing built into the ISP assembly. This method allows the belt to become tracked while working under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually change 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 adjustments be made only once 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 features are obtained, secure the locking screw.

System Configuration
#1 1 – The drive pulley is a friction drive pulley.
· The ISP is definitely a friction-driven pulley. This configuration can be specified for a tracking 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 can be used 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 can be 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 can be used to reduce side-loading of the belt perforations. Tracking precision is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metal belt systems.
OR
· The ISP is usually a timing pulley. The teeth of the ISP and the perforations of the belt are used for precise tracking control of the belt with the steering feature of the ISP used to minimize side loading of belt perforations. Again, tracking accuracy is definitely 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Note: Although it is generally not recommended to have timing elements in both the drive and driven pulleys, this design can be used selectively on metallic belt systems with long middle distances between pulleys and in applications where particulate accumulation on the top of pulley constantly changes the tracking characteristic of the belt.
