Why Consider Steel Belts for THE APPLICATION?
Engineers who specify metallic belts have possibilities to them that they don’t have when using 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 essential.
Metal belts may withstand sustained contact with 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 predicated on physical properties, availability, and cost.
Unlike the links of a chain, a steel belt is an individual element and, therefore, will not generate any component friction that requires lubrication. This reduces program maintenance, boosts reliability, and retains the system clean.
Spring steels with a higher modulus of elasticity make metal belts virtually nonstretchable when compared with additional 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 additional belt types and chain. This results in specific translation of the control program motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts could 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.
Great THERMAL AND ELECTRICAL CONDUCTIVITY:
Metal belts can 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 integrated circuits and surface area mount devices.
Unlike HTD or smooth neoprene belts, metal belts do not generate particulate and so are ideal for food and pharmaceutical processing.
CLEAN ROOM COMPATIBLE:
Metal belts do not require lubricants and will not generate dirt that could introduce foreign substances into clean area environments. Additionally, they might be sterilized in an autoclave.
Edges are simple and sizes are tightly toleranced.
Steel conveyor belt pulleys are critical to the design of any automated conveyor belt program. They act as the driving push behind the movement of the belt, making 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 with regards to pulleys. A metallic belt is only as good and precise as the pulleys. Most pulleys recommended by Ever-power are made of anodized aluminum (hard layer) with the proper friction coefficient to drive the metallic belt. Stainless steel may also be used nonetheless it is costly and heavy, although it might be indicated in certain applications where extra hardness is essential. If your application takes a lighter pulley, the professionals at Ever-power can help you select the best material.
Selecting the correct pulley size and construction can have a significant effect on the lifespan and effectiveness of a conveyor belt. Ever-power engineers have the knowledge and experience to help you choose the appropriate pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom steel conveyor belt pulleys and configurations to bring maximum efficiency to one’s body. While metal conveyor belts are usually made of stainless steel, pulleys can be created from a variety of materials, including aluminum or a variety of plastic composites. According to the unique needs of one’s body, the pulleys can also be installed 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 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 founded on the idea of changing tension associations across the width of the belt simply by adjusting the position of the pulley in accordance with the belt.
Rather than moving the pulley shaft 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 position 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 provides a simple method of steering flat metal belts. Users may combine ISP steering with the original belt tracking designs of crowning, flanging, and timing components to make a synergistic belt tracking system which efficiently 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 styles minimize downtime when replacing belts on production machinery.
· ISP system is easy to use and requires simply no special tools or schooling.
· 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 required once the belt monitoring parameters have been established.
· It prolongs belt existence 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 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 definitely a capped tube design.
· Is NEVER utilized when multiple pulleys are on a common shaft.
· Utilized selectively when the ISP is a steering roll in a multiple pulley program.
Secure 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 required tracking characteristics are obtained, prevent 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 become tracked while working under tension.

When the required tracking characteristics are obtained, avoid the shaft from rotating by securing the shaft clamp. The pulley body will today rotate about the bearing included in the ISP assembly. This technique enables the belt to become tracked while running under tension.
The Rotated Collar Approach to ISP Flat Belt Tracking
· Used to individually modify 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 recommended that these changes 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 features 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 definitely specified for a monitoring 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 is utilized 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. The 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 precision is between 0.008″ (0.203 mm) and 0.015″ (0.381 mm) for steel belt systems.
· The ISP is certainly a timing pulley. One’s 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 utilized to minimize aspect loading of belt perforations. Again, tracking accuracy is definitely 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 metallic belt systems with long center distances between pulleys and in applications where particulate accumulation on the top of pulley consistently changes the tracking characteristic of the belt.
