Metal pulley

Steel conveyor belt pulleys are critical to the look of any automated conveyor belt system. They act as the driving force behind the motion of the belt, generating torque and quickness. In very general terms it can be stated that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the overall game when it comes to pulleys. A steel belt is as good and specific as the pulleys. Most pulleys suggested by Ever-power are made of anodized aluminum (hard layer) with the right friction coefficient to drive the metal belt. Stainless steel can also be used nonetheless it is costly and heavy, although it might be indicated in certain applications where extra hardness is essential. If your application takes a lighter pulley, the specialists at Ever-power can help you select the best material.
Selecting the correct pulley size and construction can have a substantial effect on the lifespan and efficiency 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 increase product volume.
Metal Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring optimum efficiency to one’s body. While metal conveyor belts are usually made of stainless steel, pulleys can be created from a variety of materials, including light weight aluminum or a variety of plastic composites. Based on the unique needs of one’s body, the pulleys can also be fitted with customized timing attachments, relief channels, and more.
Independently Steerable Pulley
Ever-power has developed an innovative concept in flat belt tracking called the ISP (independently steerable pulley), which can be used in the next system designs:
· Two pulley conveyor systems where the ISP is the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or additional complex belt paths
Steering toned 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/down by pillow block 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 position 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 steel belts. Users may combine ISP steering with the traditional belt tracking styles of crowning, flanging, and timing elements to make a synergistic belt tracking system which efficiently and specifically steers the belt to specific tracking parameters.
Unique Characteristics and Benefits of the ISP
· Smooth belts are tracked quickly by rotating the steering collar.
· ISP designs minimize downtime when replacing belts on production machinery.
· ISP system is easy to use and requires simply no special tools or training.
· ISP simplifies the look and assembly of conveyor systems using flat belts.
· Existing idler pulleys may normally be retrofitted to an ISP without major system modifications.
· No maintenance is required once the belt tracking parameters have already been established.
· It prolongs belt life 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 avoid the shaft from turning.
The Rotated Shaft Method of ISP Flat Belt Tracking
· Is used with systems having an individual 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 usually a steering roll in a multiple pulley program.
Secure the ISP to the shaft using the split collar and locking screw included in 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 right now rotate about the bearing built into the ISP assembly. This method enables the belt to become tracked while working 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 desired tracking characteristics are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will at this point rotate about the bearing included in the ISP assembly. This method allows the belt to be tracked while working under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually change each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Used when systems have a cantilevered shafting typical of serpentine and various other complex belt path systems. It is suggested 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 desired belt tracking characteristics are acquired, 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 definitely specified for a monitoring accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to determine a lateral constraint. The steering feature of the ISP is used to set one edge 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 establish a lateral constraint. The steering feature of the ISP can be used 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. One’s 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 side loading of belt perforations. Again, tracking precision is 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Notice: Although it is normally not recommended to have timing elements in both drive and driven pulleys, this design can be utilized selectively on metallic belt systems with long center distances between pulleys and in applications where particulate accumulation on the top of pulley continuously changes the tracking characteristic of the belt.
