Installation and Maintenance of V-Belt and Timing Belt Drives

WARNING ◆ Failure

to select the proper product, to use in accordance with instructions and/or product limitations, and to regularly inspect and maintain may result in serious personal injury or death, property damage or product failure.

◆ Due to build up of static electricity, only power transmission belts constructed to meet test requirements of the RMA Technical Bulletin on static conductivity (IP3-3/1995) should be used in hazardous or explosive atmospheres, and all drive elements must be properly grounded. Any application involving such use should be reviewed with the HBD/Thermoid Technical Department before purchase or use.

◆ Do not use HBD/Thermoid power transmission products on aircraft propeller or rotor drive systems or in-flight drives. HBD/Thermoid power transmission belts are not designed or intended for aircraft use.

Metriflex®

A Complete V-Belt Line

Made to strict European tolerances and specifications to assure a highlyaccurate fit for metric drives. Sizes XPZ, XPA, XPB, SPC.

Prime Mover

Variable Speed

Premium rated heavy industrial V-belt. Oil-resistant and static* conducting. This one versatile V-belt—sized in A, B, C, D, E sections—can power virtually every drive in your plant.

For drives where variable speed control drives and mechanisms are employed. Belts’ transverse rigidity gives it excellent gripping action without crosswise distortion.

MaxipowerTM

SYNCHROBELT ® Timing Belt

A premium construction wedgetype, multiple drive belt that provides equal power transmission capacity in less space than ordinary multiple type belts. And it’s oil-resistant and static conducting* at the same price. Operates at speeds up to 6500 FPM. Sizes 3V, 5V and 8V sections.

Prime Mover Banded and Cogged Banded Premium Prime Mover V-belts are banded together to form a unitized belt set. Individual V’s are spaced to permit it to operate in regular multiple belt sheaves. This construction prevents belt whip and turnover under pulsating and shock loads. Cogged banded also available.

MaxipowerTM Banded

Functions like a timing chain or gear. Precision-molded teeth engage the mating axial grooves on pulleys, entering and leaving the grooves in a smooth, rolling manner with negligible friction. Highly versatile in application, load and speed range. Also available in Mini-Pitch.

SYNCHROTWIN Timing Belt Timing belts with driving teeth on both sides make it possible to change the direction of one or more synchronized pulleys with only one belt. The inside and outside teeth are identical as to size and pitch.

SYNCHROBELT ® HTD & STD Timing Belts

Premium Maxipower V-belts are banded together to form a unitized belt set. Individual V’s are spaced to permit it to operate in regular multiple groove 3V, 5V, 8V sheaves. This construction prevents belt whip and turnover under pulsating and shock loads. PowerPlus Maxiband® V-Belts with Kevlar reinforced cord are also available.

Bring the advantages of synchronous rubber belts to applications previously served by roller chain and gear drives. These belts do not require lubrication and, therefore, maintenance costs are minimized, and contamination from oil drip is eliminated.

MaxipowerTM Cogged Banded

Double V

Raw edge Maxipower Cogged Banded belts deliver maximum efficiency on small sheaves. Ideal for high speed motors where banded construction prevents belt whip and turnover.

Used where a series of shafts rotating in opposite directions must be driven from a single source of power. Either side of the belt can be used as a driving surface.

Kevlar Cord Prime Mover Cogged A premium construction belt for tough applications. Cogged belts offer great flexibility and increased capacity of a drive system.

We recommend our PowerPlusTM line, or Kevlar reinforced A and B sections which are stock items, since steel cable Prime Mover belts are no longer available. Kevlar reinforced C and D sections are special order items. PowerPlus A’s and B’s, along with Kevlar C’s and D’s, offer higher heat resistance than steel cable and minimal stretch.

MaxipowerTM Cogged

Novex

This belt delivers maximum efficiency on small sheaves. Its raw edge cogged narrow wedge construction is excellent for use with high speed motors.

This lightweight, versatile polyurethane belt has a unique design and side angle construction that allows for small sheave diameters, greater speed ratios and shorter centers.

FHP and PowerPlusTM

SYNCHROFORCE TM Open End Belting

For light duty service FHP offers cool, quiet operation and long service life. Because of its polyester cord construction, it will not shrink or stretch. It’s oil resistant and static conducting,* all at a standard price. For heavy-duty service, PowerPlus belts with Kevlar cord are available.

For drives not easily accessible to install endless V-belts, or for emergency use. Required length is cut off and its ends joined by a metal fastener.

Multi Ribbed

V-Link

More power per inch of drive width because on drives where multiple V-belts are required, you eliminate the free space between belts. Provides about three times the traction area of a flat belt of equal width. This belt is thinner, giving it better flexibility, reducing internal heating.

An open-end belt that doesn’t require metal fasteners, for use where obstructions prevent use of endless belts. Can be quickly and easily installed without dismantling a drive. Available in Prime Mover cross-sections.

*Static Conducting - Only those belts marked with an asterisk meet the RMA standard for static conductivity and only if new and clean. Refer to the warning on page 2.
