Why Consider Metallic Belts for Your Application?
Engineers who specify metallic belts have options available to them that they don’t have when using 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 essential.
Metal belts can withstand sustained contact with extremes of temperature, hostile conditions, and vacuum. A number of alloys can be utilized, each using its own level of resistance to chemical substances, 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 will require lubrication. This reduces system maintenance, enhances reliability, and continues the system clean.
Spring 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 powerful 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 system motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts could be fabricated with a pitch accuracy of ±0.0005 inches station to station. This high degree of precision is extremely useful in developing indexing, positioning, or processing equipment.
Great THERMAL AND ELECTRICAL CONDUCTIVITY:
Metal belts may transmit energy in the form of heat, cold, and electricity.
NO STATIC BUILD UP:
Metallic belts discharge static electrical power, a crucial capability in the manufacture of electronic components such as for example integrated circuits and surface mount devices.
Unlike HTD or smooth neoprene belts, metallic belts do not generate particulate and so are well suited for food and pharmaceutical digesting.
CLEAN ROOM COMPATIBLE:
Metal belts usually do not require lubricants and will not generate dirt that could introduce foreign substances into clean area environments. Additionally, they may be sterilized within an autoclave.
Edges are soft and measurements are tightly toleranced.
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, creating torque and swiftness. In very general conditions it can be said that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the game when it comes to pulleys. A metallic belt is as good and specific as the pulleys. Most pulleys suggested by Ever-power are constructed with anodized aluminum (hard layer) with the right friction coefficient to drive the metal belt. Stainless steel can also be used nonetheless it is pricey and heavy, though it might become indicated in certain applications where extra hardness is necessary. If your application takes a lighter pulley, the experts at Ever-power can help you select the best material.
Selecting the correct pulley size and configuration can have a significant influence on the lifespan and performance of a conveyor belt. Ever-power engineers have the data and experience to assist you choose the correct pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metal conveyor belt pulleys and configurations to bring optimum efficiency to your system. While metal conveyor belts are typically made of stainless, pulleys can be produced from a number of materials, including aluminium or a number of plastic composites. According to the unique requirements of one’s body, the pulleys can also be fitted with customized 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 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 human relationships across the width of the belt by adjusting the angle of the pulley relative to the belt.
Rather than moving the pulley shaft left/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 was created with either a skewed or an offset bore. When rotated, the collar changes the angle of the pulley body, resulting in controlled, bi-directional motion of the belt across the pulley face.
The ISP is exclusively available from Ever-power. It offers a simple approach to steering flat metallic belts. Users may combine ISP steering with the traditional belt tracking styles of crowning, flanging, and timing elements to create a synergistic belt monitoring system which effectively and exactly steers the belt to specified tracking parameters.
Unique Characteristics and Advantages of the ISP
· Flat belts are tracked quickly by rotating the steering collar.
· ISP styles minimize downtime when changing belts on production machinery.
· ISP system is simple to use and requires simply no special tools or training.
· ISP simplifies the design and assembly of conveyor systems using smooth belts.
· Existing idler pulleys can normally become retrofitted to an ISP without major system modifications.
· No maintenance is necessary once the belt monitoring parameters have already 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 machine frame using commercially available pillow blocks. A clamp is used to prevent 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 used when the pulley body is definitely a capped tube design.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP can be a steering roll in a multiple pulley program.
Secure 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 required tracking features are obtained, avoid 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 allows the belt to be tracked while operating 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 characteristics 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 enables the belt to end up being tracked while working 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 possess a cantilevered shafting typical of serpentine and additional complex belt path systems. It is suggested that these adjustments be made only when 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 features are acquired, secure the locking screw.

Number 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 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 minimal side-loading to the belt.
Number 2 2 – The drive pulley is a timing pulley.
· The ISP can be a friction driven pulley. One’s teeth of the drive pulley and the perforations of the belt set up 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.
· 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 utilized to minimize aspect loading of belt perforations. Again, tracking accuracy is certainly 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Note: Although it is normally not recommended to have timing elements in both the drive and driven pulleys, this style can be utilized selectively on metal belt systems with lengthy middle distances between pulleys and in applications where particulate accumulation on the surface of the pulley constantly changes the tracking feature of the belt.
