Why Consider Steel Belts for THE APPLICATION?
Engineers who specify metallic belts have possibilities to them that they don’t have when working with other products or components. Some essential features and benefits are talked about below.
HIGH STRENGTH-TO-WEIGHT RATIO:
This is an edge in practically every application where high strength, light weight, or both are important.
Metal belts may withstand sustained exposure to extremes of temperature, hostile environments, and vacuum. A number of alloys may be used, each using its own resistance to chemicals, humidity, and corrosion. Engineers generally decide on a belt material predicated on physical properties, availability, and cost.
Unlike the links of a chain, a metallic belt is a single element and, therefore, will not generate any component friction that will require lubrication. This reduces system maintenance, boosts reliability, and keeps the system clean.
Spring steels with a high 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 free from the pulsation of chordal action often seen in additional belt types and chain. This results in exact translation of the control system motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts can be fabricated with a pitch precision of ±0.0005 inches station to station. This high degree of precision is extremely important in designing indexing, positioning, or processing equipment.
GOOD 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 electrical power, an essential capability in the produce of electronic components such as integrated circuits and surface area mount devices.
Unlike HTD or smooth neoprene belts, steel belts usually do not generate particulate and so are well suited for food and pharmaceutical processing.
CLEAN ROOM COMPATIBLE:
Metal belts usually do not require lubricants and will not generate dust that could introduce foreign substances into clean area environments. Additionally, they may be sterilized within an autoclave.
Edges are simple and dimensions are tightly toleranced.
Metal conveyor belt pulleys are critical to the look of any automated conveyor belt program. They act as the driving push behind the movement of the belt, making torque and speed. In very general terms it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is 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 right friction coefficient to drive the metal belt. Stainless steel can also be used nonetheless it is pricey and heavy, although it might become indicated using applications where extra hardness is necessary. If your application takes a lighter pulley, the experts at Ever-power will help you select the best material.
Selecting the right pulley size and configuration can have a significant effect on the lifespan and effectiveness of a conveyor belt. Ever-power engineers have the data and experience to help you choose the right pulley type, diameter, and composition to reduce maintenance downtime and increase product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metal conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While metallic conveyor belts are usually made of stainless steel, pulleys can be produced from a number of materials, including light weight aluminum or a variety of plastic composites. Based on the unique requirements of one’s body, the pulleys may also be fitted 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 following system designs:
· Two pulley conveyor systems in which the ISP may be the idler or driven pulley
· Systems with multiple idler pulleys on a common shaft
· Systems with serpentine or other complex belt paths
Steering flat belts with an ISP is based on the concept of changing tension associations across the width of the belt simply by adjusting the angle of the pulley in accordance with the belt.
Instead of moving the pulley shaft remaining/right or up/down by pillow prevent adjustment, the ISP fits a variable steering collar and sealed bearing assembly to the body of the pulley.
The steering collar is designed with the skewed or an offset bore. When rotated, the collar changes the angle 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 metal belts. Users may combine ISP steering with the original belt tracking styles of crowning, flanging, and timing components to make a synergistic belt tracking system which effectively and exactly steers the belt to specified tracking parameters.
Unique Characteristics and Advantages of the ISP
· Smooth belts are tracked quickly by rotating the steering collar.
· ISP designs minimize downtime when changing 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 may normally end up being retrofitted to an ISP without major system modifications.
· No maintenance is required once the belt tracking parameters have already been established.
· It prolongs belt lifestyle by minimizing part 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 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 certainly a steering roll in a multiple pulley system.
Secure the ISP to the shaft using the split 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 now rotate about the bearing included in the ISP assembly. This technique allows the belt to end up being tracked while working under tension.
Protected 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 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 method enables the belt to be tracked while operating 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.
· Utilized when systems possess a cantilevered shafting typical of serpentine and additional complex belt route systems. It is suggested 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 desired belt tracking characteristics are acquired, secure the locking screw.

#2 2 – The drive pulley is a timing pulley.
· The ISP is certainly a friction driven pulley. One’s 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 accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for steel belt systems.
· The ISP can be 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 used to minimize side loading of belt perforations. Again, tracking precision is certainly 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Take note: Although it is generally not recommended to possess timing elements in both the drive and driven pulleys, this design can be utilized selectively on metallic belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the top of pulley continuously changes the tracking feature of the belt.
