BRECO® timing belts are used in applications such as industrial robots, racking systems, cutting and drawing plotters and in handling systems. The BRECOFLEXmove timing belt allows the design of belt drives that are 30% more compact. Depending on the pulley diameter, considerable costs can be. The name BRECO became the synonym for polyurethane timing belts resulting The BRECO® and BRECOFLEX® timing belts, the pulleys designed to match.

Other parameters such as braking torque, dynamic irregularities and inertias are necessary for determination purposes: Standard PU belts are reinforced by galvanised steel tension members. It has been possible to increase the number of tension members on the latter belts.
Mulco: Flighted timing belt
These high quality German products are currently operating worldwide and have a long service life, betl See more. A ttend in particular to the alignment of the pulleys and to the length of the runs preceding the guidance of the belts.
The pre-tension force to be applied to the run depends on the maximum tangential force F Nthe belt length L B number of teeth Z B and the drive configuration. Fitting with a fixed centre distance necessitates belts with a more exacting length tolerance and with more precise machining it is essential to consult our technical department.
It is constructed of an extremely wear resistant polyurethane and a high tensile steel cord tension member.
The alignment error must not be greater than the value: Little elongation of the moving belt, wich is going to engage in the glued or clamped belt. Additionally, in conjunction with a tooth side facing with polyamide the timing belt has a low coefficient of friction in the bed plate area.
An axial misalignment of the pulleys generates a force of lateral pressure by the belt on the flanges which causes wear of the belt face and an imbalance in the distribution of loads. Pulleys with a large number of teeth engaged. The flight shape for the products to be transported and for the individual transport purpose can be freely designed according to customer requests within the framework of our production possibilities.
Breco, Brecoflex, Synchroflex Timing Belts
The force transmittable by the teeth depends on the rotational tiimng and on the maximum load value that each tooth can transmit in continuous operation. Elongation of the belt is proportional to tlming force applied to the wire. The standard dimensions of flights are included in the present catalogue. This law describes deformations under load in the elasticity phase.
If the direction of rotation changes, the tension roller must preferably be positioned in the middle of the belt run.
Breco, Brecoflex, Synchroflex Timing Belts – Bervina
Overloading of the bearings, Reduced transmittable power, Excessive noise, Possible axial misalignment, Premature tooth wear. Various service parameters must be observed in order to transmit a torque under good conditions with regard to service life, noise level, bearing load, and backlash:. Strictly Necessary Cookies Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings. The use of these last three special tension members lends belts different mechanical and elastic characteristics.
Technical informations of synchronous transmissions Timing belts Thanks to its reliability and low cost a belt used to transmit motion is an essential timinh in the design of mechanisms. Other parameters such as braking torque, dynamic irregularities and inertias are necessary for determination purposes:. Centrifugal masses or rotating masses generally influence the regularity of the drive.
The following maximum numbers of teeth must be used for the calculations:. Braking can possibly exceed the load resulting from nominal utilisation or starting conditions. Consequences of incorrectly set pre-tension: The working load can be distributed better by more teeth in mesh in the toothed pulley.
We can advise you on choosing a specific variant. It has timig vulnerabilities and may not display all features on this site and other sites.
A tension member is comparable to a spring subjected to strain deformation. The purpose of the pre-tension force F pt is to guarantee a minimum tension during operation on the slack side in order to ensure that the teeth mesh correctly on the pulleys. This belt is partly made of eco-friendly polyurethane that comes from original renewable materials.
Flighted timing belt
Several factors play a role in the choice of belt, brlt as tooth profile, tension members, material, and field of application. Monofilar one tension member per belt: Clean surrounding area — Ambient temperature Good pulley quality — Observance of minimum diameters Good pre-tension Fitting with a fixed centre distance necessitates belts with a more exacting length tolerance and with more precise machining it is essential to brecp our technical department.
The flight consists of polyurethane, the same high-quality the timing belt is made of. These tension members enable breo belts to maintain their longitudinal stability. The economic aspect must be taken into account, since flanges are more cost-effective for small pulleys than for big pulleys. Alignment The alignment error must not be greater than the value: Thanks to this the belts maintain an elasticity without elongation.
The bearings must be dimensioned to support F w. For assistance please contact our technical specialist!
