Why Consider Steel Belts for Your Application?
Engineers who specify metallic belts have possibilities to them that they don’t have when working with other products or materials. Some essential features and benefits are talked about below.
HIGH STRENGTH-TO-WEIGHT RATIO:
This is an advantage in practically every application where high strength, light-weight, or both are important.
Metal belts can withstand sustained contact with extremes of temperature, hostile conditions, and vacuum. A number of alloys may be used, each using its own resistance to chemicals, humidity, and corrosion. Engineers generally select a belt material predicated on physical properties, availability, and cost.
Unlike the links of a chain, a steel belt is a single element and, therefore, does not generate any component friction that requires lubrication. This reduces program maintenance, boosts reliability, and continues the system clean.
Springtime steels with a higher modulus of elasticity make metallic belts virtually nonstretchable when compared with various other belt types and chain. This makes them ideal in high performance applications for precision positioning.
Metal belts are clear of the pulsation of chordal actions often seen in various other belt types and chain. This results in specific translation of the control program motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts could be fabricated with a pitch accuracy of ±0.0005 inches station to station. This high amount of precision is extremely valuable in designing indexing, positioning, or processing equipment.
Great THERMAL AND ELECTRICAL CONDUCTIVITY:
Metal belts may transmit energy in the kind of heat, cold, and electrical power.
NO STATIC BUILD-UP:
Steel belts discharge static electricity, an essential capability in the produce of electronic components such as integrated circuits and surface mount devices.
Unlike HTD or flat neoprene belts, metal belts do not generate particulate and so are perfect for food and pharmaceutical digesting.
CLEAN ROOM COMPATIBLE:
Metal belts do not require lubricants and can not generate dirt that could introduce foreign substances into clean area environments. Additionally, they might be sterilized within an autoclave.
Edges are even and dimensions are tightly toleranced.
Metal conveyor belt pulleys are critical to the design of any automated conveyor belt system. They act as the driving drive behind the movement of the belt, producing torque and acceleration. 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 overall game with regards to pulleys. A steel belt is only as good and precise as the pulleys. Most pulleys suggested by Ever-power are made of anodized aluminum (hard coat) with the proper friction coefficient to drive the metallic belt. Stainless steel may also be used nonetheless it is pricey and heavy, though it might be indicated using applications where extra hardness is essential. If your application takes a lighter pulley, the professionals at Ever-power will help you select the best material.
Selecting the right pulley size and configuration can have a significant influence on the lifespan and performance of a conveyor belt. Ever-power engineers possess the knowledge and experience to help you choose the correct pulley type, diameter, and composition to minimize maintenance downtime and maximize product volume.
Metal Conveyor Belt Pulley Types
Ever-power designs custom steel conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While steel conveyor belts are usually made of stainless steel, pulleys can be produced from a variety of materials, including aluminum or a number of plastic composites. With respect to the unique requirements 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 smooth 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 various other complex belt paths
Steering smooth belts with an ISP is founded on the idea of changing tension associations over the width of the belt by adjusting the angle of the pulley relative to the belt.
Instead of moving the pulley shaft left/right or up/down by pillow block adjustment, the ISP fits a adjustable steering collar and sealed bearing assembly to your body of the pulley.
The steering collar was created with either a skewed or an offset bore. When rotated, the collar changes the position of the pulley body, leading to controlled, bi-directional motion of the belt over the pulley face.
The ISP is exclusively available from Ever-power. It provides a simple method of steering flat steel belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing elements to create a synergistic belt monitoring system which effectively and exactly steers the belt to specific tracking parameters.
Unique Characteristics and Benefits of the ISP
· Flat belts are tracked quickly by rotating the steering collar.
· ISP styles minimize downtime when replacing belts on creation machinery.
· ISP system is simple to use and needs simply no special tools or training.
· ISP simplifies the design and assembly of conveyor systems using smooth belts.
· Existing idler pulleys can normally be retrofitted to an ISP without major system modifications.
· No maintenance is necessary once the belt monitoring parameters have already been established.
· It prolongs belt existence 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 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 certainly a capped tube style.
· 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.
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 device. When the desired tracking features are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will right now rotate about the bearing included in the ISP assembly. This method enables the belt to become tracked while working under tension.

The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually adjust each belt/pulley combination when there are multiple pulleys on a common shaft.
· Utilized when systems possess a cantilevered shafting typical of serpentine and other complex belt path systems. It is recommended that these changes 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 features are acquired, secure the locking screw.

#1 1 – The drive pulley is a friction drive pulley.
· The ISP can be a friction-driven pulley. This configuration is certainly specified for a tracking precision 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 is utilized to set one edge of the belt against the flange with minimal side-loading to the belt.
Number 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 set up a lateral constraint. The steering feature of the ISP is utilized to reduce side-loading of the belt perforations. Tracking precision is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for steel belt systems.
· The ISP can be a timing pulley. One’s 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 used to minimize side loading of belt perforations. Again, tracking accuracy is usually 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Note: Although it is generally not recommended to possess timing elements in both drive and driven pulleys, this design can be used selectively on metallic belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the surface of the pulley constantly changes the tracking characteristic of the belt.
