Why Consider Metal 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 important 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 essential.
DURABILITY:
Metal belts may withstand sustained exposure to extremes of temperature, hostile conditions, and vacuum. A number of alloys can be utilized, each with its own level of resistance to chemical substances, humidity, and corrosion. Engineers generally decide on a belt material based on physical properties, availability, and cost.
NO LUBRICATION:
Unlike the links of a chain, a steel belt is a single element and, therefore, will not generate any component friction that will require lubrication. This reduces system maintenance, increases reliability, and will keep the system clean.
NONSTRETCHABLE:
Springtime steels with a high modulus of elasticity make steel belts virtually nonstretchable in comparison with various other belt types and chain. This makes them ideal in high performance applications for precision positioning.
SMOOTH OPERATION:
Metal belts are clear of the pulsation of chordal action often seen in various other belt types and chain. This results in precise 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 amount of precision is extremely precious 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:
Metallic belts discharge static electrical power, a crucial capability in the produce of electronic components such as for example integrated circuits and surface mount devices.
CLEAN:
Unlike HTD or toned neoprene belts, metal belts do not generate particulate and are ideal for food and pharmaceutical digesting.
CLEAN ROOM COMPATIBLE:
Metal belts usually do not require lubricants and can not generate dust that could introduce foreign substances into clean area environments. Additionally, they may be sterilized in an autoclave.
PRECISE CONSTRUCTION:
Edges are smooth and measurements are tightly toleranced.

Metallic conveyor belt pulleys are critical to the design of any automated conveyor belt program. They become the driving drive behind the movement of the belt, producing torque and rate. 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 when it comes to pulleys. A metal belt is as good and precise as the pulleys. Most pulleys recommended by Ever-power are made from anodized aluminum (hard coating) with the right friction coefficient to operate a vehicle the metal belt. Stainless steel may also be used nonetheless it is costly and heavy, although it might end up being indicated in certain applications where extra hardness is necessary. If your application takes a lighter pulley, the specialists at Ever-power can help you select the best material.
Selecting the right pulley size and construction can have a significant influence on the lifespan and performance of a conveyor belt. Ever-power engineers have the data and experience to help you choose the appropriate pulley type, diameter, and composition to minimize maintenance downtime and increase product volume.
Metal Conveyor Belt Pulley Types
Ever-power designs custom metallic 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 created from a number of materials, including light weight aluminum or a number of plastic composites. Based on the unique requirements of one’s body, the pulleys may also be installed with custom timing attachments, relief channels, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking concept in toned 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 various other complex belt paths
Steering smooth belts with an ISP is based on the concept of changing tension human relationships over the width of the belt 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, 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 approach to steering flat metallic belts. Users may combine ISP steering with the traditional belt tracking styles of crowning, flanging, and timing components to make a synergistic belt monitoring system which efficiently and precisely 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 easy to use and needs simply no special tools or teaching.
· ISP simplifies the design and assembly of conveyor systems using smooth belts.
· Existing idler pulleys may normally become retrofitted to an ISP without major system modifications.
· No maintenance is necessary once the belt monitoring parameters have been established.
· It prolongs belt life by minimizing side 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 a single pulley on the shaft.
· Is ALWAYS utilized when the pulley body is a capped tube style.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP is definitely a steering roll in a multiple pulley system.
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 features 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 end up being tracked while working under tension.
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, 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 technique enables the belt to end up being tracked while running under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually adapt each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Used when systems possess a cantilevered shafting typical of serpentine and other complex belt route 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 required belt tracking characteristics are attained, 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 mounted on the pulley body to determine a lateral constraint. The steering feature of the ISP is used to set one advantage of the belt against the flange with minimal side-loading to the belt.
System Configuration
Number 2 2 – The drive pulley is a timing pulley.
· The ISP is 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 can be used to reduce 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.
OR
· The ISP can be 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 utilized to minimize part loading of belt perforations. Again, tracking precision is definitely 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Note: Although it is normally not recommended to possess timing elements in both the drive and driven pulleys, this style can be used selectively on metal belt systems with long middle distances between pulleys and in applications where particulate accumulation on the surface of the pulley consistently changes the tracking feature of the belt.
