V Belt Aspira Vs Ahm

V Belt Aspira Vs Ahm. Welcome to our range of Dunlop & Medway V belts V belts – which also known as Vee belts and wedge belts – are designed to prevent slippage and alignment problems They take their name from the Vshape of the belt tracks which is what prevents the belt from slipping With greater load the belt will also tend to wedge into the groove hence.

Bearingtech supply a large range of V Belts this page will guide you through the process of identifying what v belt or drive belt you need in an easy to understand format and will allow you to purchase the Vee belt you need Each Wedge shaped belt is separated into it different sections or types for an easy and simple shopping experience.

The Common Types of V Belts & Their Standard Sizes

The types of Vbelts and their standard sizes There are three common V belt types Classical Vbelt (classified by their dimensions from A to E) Narrow V series (classified by their dimensions 3V 5V and 8V) and light duty Fractional Horsepower belt (classified by their dimensions 2L 3L 4L 5L) Their counterpart cogged belt is classified.

It depends on the application Following are some environmental and application design criteria that will influence belt selection 1 Ambient temperature 2 Oil resistance 3 Ozone resistance 4 Static conductivity 5 Power capacity 6 Pulsation or shock loading 7 Small sheave diameters 8 Backside idlers 9 Misalignment tolerance 10 Serpentine or quarter turn layout 11 Minimal takeup 12 Clutching 13 High speeds 14 Energy efficiency 15 Dust and abrasives As you can see there are many factors to consider before ch Unlike flat belts which rely solely on friction and can track and slip off pulleys Vbelts have sidewalls that fit into corresponding sheave grooves providing additional surface area and greater stability As belts operate belt tension applies a wedging force perpendicular to their tops pushing their sidewalls against the sides of the sheave grooves which multiplies frictional forces that allow the drive to transmit higher loads (Figure 2) How a Vbelt fits into the groove of the sheave while operating under tension impacts its performance Vbelts are made from rubber or synthetic rubber stocks so they have the flexibility to bend around the sheaves in drive systems Fabric materials of various kinds may cover the stock material to provide a layer of protection and reinforcement Vbelts are manufactured in various industry standard crosssections or profiles including the following 1 Classical 2 Narrow 3 Metric 4 Fractional Horsepower The classical Vbelt profile dates back to industry standards developed in the 1930s Belts manufactured with this profile come in several sizes (A B C D E) and lengths (Figure 3) and are widely used to replace Vbelts in older existing applications Vbelts with a narrow profile (3V 5V 8V) have more steeply angled sidewalls than classical Vbelts (Figure 4) providing increased wedging action and higher load capacity (up to 3x that of comparable classical Vbelts) Metric Vbelts have profiles that adhere to international standards set by organizations such as ISO (International Organization for Standardization) and DIN (the German Institute for Standardization) (Figure 5) They are used to replace belts on industrial machinery manufactured in other parts of the world The fractional horsepower Vbelt profile All of the Vbelt types noted above are typically available from manufacturers in “notched” or “cogged” versions Notches reduce bending stress allowing the belt to wrap more easily around small diameter pulleys and allowing better heat dissipation Excessive heat is a major contributor to premature belt failure Engineering a notched belt is a balancing act between flexibility tensile cord support and stress distribution Precisely shaped and spaced notches help to evenly distribute stress forces as the belt bends thereby helping to prevent undercord cracking and extending belt life (Figure 7) For applications with vibrating or pulsating loads especially with long center distances joined Vbelts may be the answer A joined Vbelt is in essence a number of single Vbelts joined together with a continuous tieband across the back (see Figure 8) A joined Vbelt increases lateral rigidity to reduce belt whip and maintain stability under shock loads It also simplifies installation and tensioning compared with multiple single belts Figure 9 describes the constructional components of standard and notched Vbelts Each component has a vital role to play in how well Vbelts perform and how long they last Different materials and configurations can influence belt performance characteristics in specific applications The tensile cord is the loadcarrying component of a Vbelt Most Vbelts are made with polyester cords although some belts are constructed with aramid or Kevlar? cords which offer higher tensile strength limit stretch and can handle heavier shock loads In a wellengineered Vbelt the tensile cords and rubber body of the belt are chemically bonded to form one unit allowing for equal load distribution and longer belt life Tensile cords are supported by rubber stocks both above (over cord) and beneath (under cord) Various synthetic rubber stocks are used by different manufacturers to provide heat resistance and reduce wear Some highperformance synthetic rubber compounds such as ethylene sig Sheaves are essential Vbelt drive components As noted earlier how well a Vbelt fits into the sheave determines how much power the belt drive can transmit and how efficiently it operates Proper fit is a function of both the belt and the metal sheave A wellengineered belt and a wellmachined matching sheave provide the optimal combination Many users replace Vbelts repeatedly without bothering to check the sheaves for wear A worn broken or damaged sheave decreases belt life Sheave damage could result from incorrect installation such as overtightening the bushing bolts or prying the belt onto the sheave Another cause of sheave damage is debris falling into the drive which can be prevented by installing a drive guard Signs of sheave wear include groove sidewall cupping and/or a polished groove sidewall with ridges Use a sheave gauge (Figure 10) to detect excessive sheave groove wear and replace sheaves immediately when worn Advances in Vbelt technology present users the opportunity to upgrade older drives and gain improvements in performance while saving time and money For example industry standard Vbelts subject to extreme operating conditions such as stifling heat inside a belt guard can fail prematurely from heat cracks stretching or excessive wear Frequently retensioning and replacing the belts leads to downtime inefficiency and loss of productivity With today&#39s new technologies however you can upgrade to notched Vbelts made from an ethylene rubber material that can withstand temperature extremes from 70°F (57°C) to +250°F (+121°C) an 88% improvement over the temperature range for industry standard Vbelts These newer belts resist hardening to avoid cracking offer improved flexibility and run smoother in the sheaves to reduce vibration and extend the life of other drive components such as shafts and bearings As another example replacing an older classical Vbelt drive with a From giant rock crushers to tiny sewing machines Vbelts have found their way into countless industrial applications Today&#39s Vbelts are marvels of modern technology reflecting the latest advances in mechanical and chemical engineering The key thing to remember about Vbelts whether on a new drive or a replacement is “know thy application” The right belt for the job along with proper installation and maintenance will provide you troublefree service for the designed life of the drive For more information Gates Corporation Phone (303) 7445800 PTPAsupport@gatescom wwwGatescom/vbelts.
