TRANSMISSION BELTING SECTOR

MTS INCORPORATION



















































































































MTS V-BELTS ARE MANUFACTURED UNDER STRICT VIGILANCE AND OBSERVATION OF THE STATE OF ART OF MODERN TECHNOLOGY WITH REINFORCEMENT OF HIGHLY SHOCK - LOAD RESISTANT SYNTHETIC CORDS COMBINED WITH SPECIAL RUBBER COMPOUND AND ULTIMATELY JACKETED TO OBTAIN MAXIMUM LlFE AND SMOOTH RUN OF THE DRIVE.

BELT CONSTRUCTION


TECHNICAL CHARACTERISTICS
A. Cover... The bias-cut cover fabric is impregnated with special rubber to protect the inner part of the belts and provide strong abrasion resistance on the pulley groove.

B. Tension Member... The load carrying cords are tough polyester / aramide cords that have been specially treated to temper the cords to their point of high strength, low elongation and greater resistance to bending fatigue.

C. Top Compression Section... The rubber used in this section is compounded to withstand sudden shock loads and to keep the belt flexing readily when passing over the pulleys.

D. Insulation Section... The insulation section holds the tension binding section for extra strong adhesion between cords and the top and bottom compression section.

E. Bottom Compression Selection... This section holds the normal cross section of the belts and is compounded to resist compression fatigue and heat for longer service life.

RECOMMENDATION FOR DRIVE DESIGN

Design Formula.

(1) Speed Ratio R = rev/m~n of the Faster Shaft
rev/mln of the Slower Shaft  
= Pitch Dia of large pulley
Pitch Dia of smaller pulley
= D/d

 (2) Pitch length of belt., L = 2C + (D-d)2 / 4C + 1.57 (D+d)  (C = Center Distance)

(3) Center Distance, C = A+ ~in case center distance is not specified choose C = 2 X.J (D+d) d
                        
Where A = L/4 0.3925 (D+d)              B = (D - d)2 / 8
                                   
(4) Belt Velocity/Peripheral speed (V)=  DN / 19100  m/Sec (Should not normally exceed 30 m/Sec.)

Selection.

 

(a) Service Factor: (SF)
Consult SF table and select suitable factors. In case of speed increasing drive, that additional factors as per the table

(b) Design Power (DP)
Multiply the normal running power (RP) with(SF). DP = RP X SF
 
(c) Selection of belt cross section, - consult cross section table and select the belt cross section on the basis DP and (rmp of faster shaft) (Table Graph)

(d) Pulley selection - Select a suitable pulley combination which should give proper speed ratio.
(Pulley Pcd. should not be below the recommended minimum) (Table 1)

(e) Basic Power belt-Find out rated power (P) from the power rating graph.

(f) Corrected power rating (CP) = (P+ Speed Ratio Increment)X Belt factor (LF) X Arc of contact factor ( CF ). (Consult Table2 &3)

(G) Number of belt required N= DP / CP

APPLICATIONS:
   

APPLICATIONS :- These Belts are being used in :

 

SPECIAL FEATURE:

1.) Automobile - Car, LCV, Commercial Vehicles, Tractors and Agricultural Machineries ( Harvestor Combines), Moped ect.

2.) High speed drives in Textile Industries, Cotton Jinning, Modern Consumer Durables (Washing Machine).



 

(A.) Side -Wall Wear Resistance ­Excellent.
(B.) Bending stress Resistence ­Excellent.
(C.) Noise Level- Good.
(D.) Heat & Oil Resistance - Excellent.
(E.) Static Electricity Generation - Nil.





NB:­ Present days, Cars with high speed engine I air-condirioning compressor-drives have (till date) no alternatives but to use Cogged Belts since:

  1. Limitations in pulley size with obvious high RPM.
  2. Generation of heat in covered area for compressor running in conditioning the air inside the Car.

A comprehensive list of application in automotive under Indian Subcontinent ( as per list)

(A.) SECTION AND SIZE- Since section and size of the belts in so many areas are reciprocal to automobile manufactures of the World; it is advisable for the Foreign - Buyer to either suggest the total size - Top Width x Thickness x Length (1/c,O/C,PL) orthe Code No., on the Belts.

(B.) POLYESTER DIPPED CORD - Properly heat-set and simultaneously rubberized polyester cords are built in, Under tension to prove maximum bending frequency without variation on load. Of course different no. of plies of PFY are used in compatiation towards section

(C.) INSULATION COMPOUND - The same compound with Synthetic Rubber is applied in Traction Layer and Compression Rubberto privide high Heat Resistance and Flexibility and Bonding in totality.

(D.) BASE (COMPRESSION) RUBBER COMPOUND - High Heat, Abrasion-Resistant Compound for compromising the compression the load, bonding and provide smooth running.


" BLACK TIGER" MTS BELTS ARE MANUFACTURED IN O/C.

  1. Slabs ofthe specific Thickness and length in O/C.
  2. Thickness and Coggs and are maintained to generate and assure

FLEXIBILITY - Cogged Format gives higher flexibility resulting in efficient dissipation. Strong Tensile Member and Transverse Modulus provide high Horse - Power Rating. Special Rubber Compound becomes high Heat Resistant, Special Homogenlousity on total shape and Ultimately smooth running.

INSTRUCTIONS FOR PROPER USE
OF MTS V-BELTS

ALIGNMENT

After installing the belts, it should be checked that the pulleys are properly aligned. Failure to do so will reduce the drive and shorten the V-Belt life.The diagrams here show some of the common mis-alignments.

 

***Do not use belt dressings.
*** Normal V-belts will withstand temperature upto 70°C working temperature above this level can shorten belt life.

*** Belt overloading is a sure sign offaulty drive design. Do not try to increase power transmission by applying more belt tension; this will only cause belt rupture and is likely to harm the shaft bearings.

*** In case of replacing the whole set must be replaced instead oftrying to fit in a new belt.

** Drive must be equipped with belts of the correct type and size: as well as the number necessary to transmit
design power. Belt cross-sections and sheave grooves must match.

***Sheaves must be in perfect alignment and grooves free from rust, dirt and burrs.

***After running in for about 15 minute at full load, the belts will have seated in the grooves. At the same time they will have stretched by about 0.5% to 1 % of nominal length. After retightening, belt tension must be checked periodically, since slip caused by slackness will soon destroy the belts.

*** Guard belts against oil, grease, solvents etc.

Storage: V - Belts should be stored in stock room and contact with hot pipes and direct sunlight carefully avoided. Where possible handle the belts loosely in single or triple coils. Always avoid tying them tightly with spring.

Installation: In assembling a drive, the motor should be moved towards the driven unit, so that the belt may be placed in their respective grooves by hand. The belt should not be forced on the pulley with screw drivers, wedges, crow-bars or any other type of implement. When the belts have been placed in the pulley grooves, the motor should then be moved away form the driven unit to apply uniform tension to the belts.
