Uliflex Is Here To Guide You On: How To Determine The Specifications And Types of Industrial Belts.

For a long time, it is not easy for users to correctly judge the type of industrial belt used by mechanical equipment in industrial production. As an important part of mechanical transmission system, the correct judgment of the model and specification of industrial belt is very important for equipment operation and maintenance.

Today, Uliflex will share the "method of judging the model and specification of industrial belt" with its more than 20 years of experience in the industrial belt industry.

Generally speaking, there are four main categories of industrial belts in the current industrial market ：

1.V-belt ：

· Ordinary V-belt : Z-type, A-type, B-type, C-type, D-type, E-type

· Narrow V-belt : SPZ, spa, SPB, SPC (ordinary narrow V-belt) and XPZ, XPA, XPB, XPC (strong narrow V-belt)

· Features : the section is trapezoidal, and the power is transmitted by the friction between the two sides and the pulley groove

2. Timing belt ：

       · Features : meshing transmission between belt teeth and belt teeth, accurate transmission ratio, no sliding

          · Common models : 3M, 5m, 8m, etc. the number represents the pitch (mm)

3. Flat belt ：

         · Features : rectangular section, simple structure, suitable for high-speed transmission

· Specification : 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. according to thickness

4. Conveyor belt ：

· Material : rubber, polyester fiber, nylon, metal mesh belt, etc

· Width : common 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, etc

Secondly, the main types and specifications of the above four industrial belts are expressed as follows :

1. Model and specification of V-belt (usually composed of letters and numbers)：

· Letter part : represents belt type and section size

 · For example : type A (13mm wide and 8mm thick), type B (17mm wide and 11mm thick), type C (22mm wide and 14mm thick)

· Digital part : represents the belt length

 · LI : inner perimeter (for example, 2800li means 2800mm inner perimeter)

·LA : outer perimeter

·Ld : reference length/pitch length

·Lw : effective length

2. The model and specification of synchronous belt can be expressed in English and metric systems：

                A. (metric system: composed of width - model - length)

              B. (English system: composed of length - model - width)

            The following is an example of the English system of expression ：

     · Length code : for example, 200 represents the actual length of 508mm

     · Model letter : for example, XL stands for pitch of 5.08mm

      · Width code : for example, 037 represents a width of 9.5mm

          Example : 200 XL 037 represents a timing belt with a length of 508mm, a pitch of 5.08mm and a width of 9.5mm

3. Flat belt specification expression (main specification parameters) :

             · Thickness : 1-4mm, tolerance range ± 0.1~± 0.4mm

  · Width : 10mm-1000mm

   · Length : cut as required, and connect both ends of flat belt with ends

In addition to the above judgment on the specifications of industrial belts, users should also understand the following precautions for selecting industrial belts ：

1. Load requirements ：

· Consider the maximum load and load characteristics (impact load or continuous high load)

2. Speed and tension ：

· High speed operation requires special design to reduce heat accumulation

· Maintain proper tension to extend service life

· Maintain proper tension to extend service life

3. Working environment ：

· Industrial belts with high temperature resistant materials shall be selected for use in high temperature environment

· Industrial belts with corrosion resistant belts to be selected for use in chemical environments

4. Size matching ：

· Ensure that the belt size is compatible with the drive system (e.g. length, width and thickness)

5. Application scenarios ：

· Heavy duty low speed transmission: choose rubber belt

· High speed and high precision transmission: choose polyester or nylon belt

Through the above mentioned methods, I believe that readers will have a basic understanding of the judgment of industrial belt specifications and models.
