HTD belts
Mitsuboshi H timing belts enable the delivery of form-locking power transmission for high torque, something which, up to now, has only been possible by using chain drives or gear drives. Thanks to the tooth profile, the stress distribution is considerably improved and a greater overall belt load is possible.

In order to achieve optimal performance and as long a service life as possible, timing belts have to be correctly installed, correctly tightened and correctly aligned. Prior to installation, it is always recommendable to inspect the belts for any possible damage resulting from transport or storage.
The Correct Mounting
Pulleys and, of course, belts themselves always have to be mounted with the correct alignment. This means that belts cannot be bent or buckled in any way, which could lead to a drop below the minimum permissible pulley diameter. That corresponds to approximately 50 mm for belts with a pitch of 8 mm and about 125 mm for those belts with a 14 mm pitch. Imbalanced drives cause a variety of belt tension problems and edge stresses and are also responsible for extreme lateral movement, the undesired wobble. All this leads to increased operating noise and more wear and tear on the belt. Therefore the parallelism error of the pulleys should only amount to a maximum of 0.5% of the centre distance. Angle accuracy is to be maintained by keeping misalignment down to 0.25° at the very most.
Pre-Tensioning The Belt Correctly
Firstly the belt always has to be tightened in line with the calculated pre-tensioning force and checked after a running-in period of about 5 minutes. The belt is then to be retightened according to the relevant value, should it have shifted or altered its position in any way. Finally after a further 8 hours of operating, the belt is to be once again inspected and, if necessary, tightened to comply with the required value that has already been calculated.
