Why Consider Metallic Belts for THE APPLICATION?
Engineers who specify steel belts have possibilities to them that they do not have when working with other products or materials. Some important 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 can withstand sustained exposure to extremes of temperature, hostile environments, and vacuum. A variety of alloys may be used, each using its own resistance to chemical substances, humidity, and corrosion. Engineers generally decide on a belt material predicated on physical properties, availability, and cost.
Unlike the links of a chain, a metal belt is a single element and, therefore, does not generate any component friction that requires lubrication. This reduces program maintenance, increases reliability, and continues the system clean.
Spring steels with a high modulus of elasticity make metal belts virtually nonstretchable when compared with 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 actions often seen in other belt types and chain. This results in precise 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 amount of precision is extremely beneficial in designing 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, a crucial capability in the manufacture of electronic components such as integrated circuits and surface area mount devices.
Unlike HTD or flat neoprene belts, steel belts usually do not generate particulate and so are well suited for food and pharmaceutical processing.
CLEAN ROOM COMPATIBLE:
Metal belts do not require lubricants and can not generate dirt that could introduce foreign substances into clean room environments. Additionally, they may be sterilized within an autoclave.
Edges are simple and dimensions are tightly toleranced.
Metallic conveyor belt pulleys are critical to the look of any automated conveyor belt system. They become the driving push behind the movement of the belt, creating torque and swiftness. In very general conditions it can be stated that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision is the name of the game with regards to pulleys. A steel belt is as good and precise as the pulleys. The majority of pulleys recommended by Ever-power are constructed with anodized aluminum (hard coat) with the proper friction coefficient to operate a vehicle the metal belt. Stainless steel can also be used but it is pricey and heavy, though it might become indicated using applications where extra hardness is essential. If your application requires a lighter pulley, the specialists at Ever-power will help you choose the best material.
Selecting the correct pulley size and configuration can have a substantial influence on the lifespan and effectiveness of a conveyor belt. Ever-power engineers have the data and experience to assist you choose the correct pulley type, diameter, and composition to minimize maintenance downtime and increase product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom steel conveyor belt pulleys and configurations to bring optimum efficiency to one’s body. While steel conveyor belts are typically made of stainless, pulleys can be created from a variety of materials, including aluminium or a number of plastic composites. Depending on the unique needs of one’s body, 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 toned belt tracking called the ISP (independently steerable pulley), which can be utilized in the next system designs:
· Two pulley conveyor systems where 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 toned belts with an ISP is based on the concept of changing tension relationships across the width of the belt simply by adjusting the position of the pulley relative to the belt.
Rather than moving the pulley shaft remaining/right or up/straight 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 was created with either a skewed or an offset bore. When rotated, the collar changes the angle of the pulley body, leading to 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 steel 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 specific tracking parameters.
Unique Characteristics and Benefits of the ISP
· Toned 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 requires no special tools or schooling.
· ISP simplifies the design and assembly of conveyor systems using flat belts.
· Existing idler pulleys may 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 machine frame using commercially available pillow blocks. A clamp can be used to avoid 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 used when the pulley body is certainly a capped tube style.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Used selectively when the ISP is a steering roll in a multiple pulley program.
Protected the ISP to the shaft using the split collar and locking screw included in the ISP. Rotate the shaft and collar as a unit. When the required 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 technique enables the belt to end up being tracked while operating under tension.
Protected 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 characteristics are obtained, prevent the shaft from rotating by securing the shaft clamp. The pulley body will now rotate about the bearing built into the ISP assembly. This method allows the belt to be tracked while working under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually modify each belt/pulley combination whenever there are multiple pulleys on a common shaft.
· Utilized when systems have a cantilevered shafting typical of serpentine and other complex belt path systems. It is recommended 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 desired belt tracking characteristics are obtained, 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 is specified for a tracking accuracy of 0.030″ (0.762 mm) or greater.
· Teflon® flanges are attached to the pulley body to establish a lateral constraint. The steering feature of the ISP can be 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 definitely 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 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 is 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 aspect 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 drive and driven pulleys, this style can be utilized selectively on metal belt systems with long center distances between pulleys and in applications where particulate accumulation on the top of pulley continuously changes the tracking characteristic of the belt.
