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 discussed 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 may withstand sustained exposure to extremes of temperature, hostile conditions, and vacuum. A variety of alloys may be used, each using its own resistance to chemicals, humidity, and corrosion. Engineers generally select a belt material predicated on physical properties, availability, and cost.
Unlike the links of a chain, a metallic belt is a single element and, therefore, will not generate any component friction that will require lubrication. This reduces system maintenance, increases reliability, and maintains the system clean.
Springtime steels with a higher modulus of elasticity make steel belts virtually nonstretchable in comparison with other belt types and chain. This makes them ideal in powerful 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 specific translation of the control program motion profile.
ACCURATE AND REPEATABLE:
Metal timing belts can be fabricated with a pitch accuracy of ±0.0005 inches station to station. This high degree of precision is extremely precious in creating indexing, positioning, or processing equipment.
Great 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 electricity, an essential capability in the manufacture of electronic components such as for example integrated circuits and surface area mount devices.
Unlike HTD or toned neoprene belts, metallic belts do not generate particulate and so 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 space environments. Additionally, they might be sterilized in an autoclave.
Edges are simple and measurements are tightly toleranced.
Steel conveyor belt pulleys are critical to the design of any automated conveyor belt program. They become the driving drive behind the motion of the belt, producing torque and quickness. In very general terms it can be stated that pulleys are categorized as friction drive or timing pulleys (type I and II). Precision may be the name of the game with regards to pulleys. A steel belt is only as good and specific as the pulleys. Many pulleys recommended by Ever-power are made from anodized aluminum (hard layer) with the right friction coefficient to operate a vehicle the metallic belt. Stainless steel can also be used nonetheless it is expensive and heavy, although it might end up being indicated in certain applications where extra hardness is essential. If your application takes a lighter pulley, the specialists at Ever-power will help you select the best material.
Selecting the right pulley size and configuration can have a significant influence on the lifespan and efficiency of a conveyor belt. Ever-power engineers possess the knowledge and experience to help you choose the right pulley type, diameter, and composition to reduce maintenance downtime and maximize product volume.
Metallic Conveyor Belt Pulley Types
Ever-power designs custom metallic conveyor belt pulleys and configurations to bring optimum efficiency to one’s body. While steel conveyor belts are typically made of stainless steel, pulleys can be produced from a number of materials, including aluminium or a number of plastic composites. According to the unique needs of your system, the pulleys can also be fitted with custom timing attachments, relief stations, and more.
Independently Steerable Pulley
Ever-power has developed an innovative concept in flat belt tracking called the ISP (independently steerable pulley), which can be utilized 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 smooth belts with an ISP is based on the idea of changing tension relationships over the width of the belt simply by adjusting the angle of the pulley relative to the belt.
Instead of 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 is designed with the skewed or an offset bore. When rotated, the collar changes the position of the pulley body, resulting in 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 original belt tracking designs of crowning, flanging, and timing components to create a synergistic belt tracking system which efficiently 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 styles minimize downtime when changing belts on creation machinery.
· ISP system is simple to use and requires no special tools or teaching.
· ISP simplifies the look and assembly of conveyor systems using toned belts.
· Existing idler pulleys can normally be retrofitted to an ISP without main system modifications.
· No maintenance is necessary once the belt tracking parameters have already been established.
· It prolongs belt lifestyle by minimizing side loading when working with 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 prevent the shaft from turning.
The Rotated Shaft Method of ISP Flat Belt Tracking
· Is used with systems having a single pulley on the shaft.
· Is ALWAYS used when the pulley body is definitely a capped tube style.
· Is NEVER used when multiple pulleys are on a common shaft.
· Used selectively when the ISP is definitely a steering roll in a multiple pulley system.
Secure 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, avoid 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 allows the belt to become tracked while working under tension.
Secure the ISP to the shaft using the split collar and locking screw built into 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 today rotate about the bearing built into the ISP assembly. This technique allows the belt to become tracked while working under tension.
The Rotated Collar Method of ISP Flat Belt Tracking
· Used to individually change each belt/pulley combination when there are multiple pulleys on a common shaft.
· Utilized when systems possess a cantilevered shafting typical of serpentine and other complex belt route systems. It is suggested that these adjustments 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 required belt tracking features are attained, secure the locking screw.

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