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 discussed 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 can be utilized, each with 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 an individual element and, therefore, will not generate any component friction that will require lubrication. This reduces program maintenance, improves reliability, and retains the system clean.
Springtime steels with a higher modulus of elasticity make metal belts virtually nonstretchable in comparison with 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 action often seen in various other belt types and chain. This results in exact translation of the control program 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 beneficial in creating indexing, positioning, or processing equipment.
Great THERMAL AND ELECTRICAL CONDUCTIVITY:
Metal belts can transmit energy in the kind of heat, cold, and electricity.
NO STATIC BUILD UP:
Metal 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, metallic belts usually do not generate particulate and are ideal for food and pharmaceutical digesting.
CLEAN ROOM COMPATIBLE:
Metal belts do not require lubricants and will not generate dust that would introduce foreign substances into clean area environments. Additionally, they may be sterilized in an autoclave.
Edges are even 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 pressure behind the motion of the belt, creating torque and quickness. 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 exact as the pulleys. Most pulleys recommended by Ever-power are made of anodized aluminum (hard coat) with the right friction coefficient to operate a vehicle the steel belt. Stainless steel can also be used but it is pricey and heavy, though it might be indicated in certain applications where extra hardness is necessary. If your application takes a lighter pulley, the specialists at Ever-power will help you choose the best material.
Selecting the right pulley size and configuration can have a substantial effect on the lifespan and efficiency 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 increase product volume.
Steel Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring optimum efficiency to one’s body. While metallic conveyor belts are usually made of stainless steel, pulleys can be created from a variety of materials, including aluminium or a variety of plastic composites. Depending on the unique requirements of your system, the pulleys can also be installed with custom timing attachments, relief stations, and more.
Independently Steerable Pulley
Ever-power has developed a forward thinking 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 may be 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 over the width of the belt by adjusting the position of the pulley in accordance with the belt.
Rather than moving the pulley shaft still left/right or up/down by pillow block adjustment, the ISP fits a variable steering collar and sealed bearing assembly to the body of the pulley.
The steering collar is designed 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 method of steering flat metallic belts. Users may combine ISP steering with the traditional belt tracking designs of crowning, flanging, and timing components to create a synergistic belt monitoring system which effectively and exactly steers the belt to specified tracking parameters.
Unique Characteristics and Benefits 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 easy to use and requires no special tools or schooling.
· ISP simplifies the design and assembly of conveyor systems using toned belts.
· Existing idler pulleys can normally become retrofitted to an ISP without major system modifications.
· No maintenance is required once the belt tracking parameters have been established.
· It prolongs belt lifestyle by minimizing part 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 is utilized 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 used when the pulley body is certainly a capped tube design.
· Is NEVER used when multiple pulleys are on a common shaft.
· Utilized selectively when the ISP is certainly 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 desired tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will now rotate about the bearing built into the ISP assembly. This technique enables 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 unit. When the desired tracking characteristics 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 technique enables the belt to become tracked while running under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually adjust each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Utilized when systems possess a cantilevered shafting typical of serpentine and various other complex belt route systems. It is suggested that these changes be made only when 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 required belt tracking features are obtained, secure the locking screw.

Number 1 1 – The drive pulley is a friction drive pulley.
· The ISP is a friction-driven pulley. This configuration is 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 used to set one edge of the belt against the flange with reduced side-loading to the belt.
#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 is used to minimize side-loading of the belt perforations. Tracking accuracy is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for metal belt systems.
· The ISP is certainly a timing pulley. The 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 part loading of belt perforations. Again, tracking precision is certainly 0.008″ (0.203 mm) to 0.015″ (0.381 mm) for metal bells.
Notice: Although it is normally not recommended to possess timing elements in both drive and driven pulleys, this style can be used selectively on steel belt systems with long middle distances between pulleys and in applications where particulate accumulation on the top of pulley continuously changes the tracking feature of the belt.
