The utility model relates to a pressure synchronous belt transmission device with small tooth difference, which belongs to the field of transmission machinery. It is composed of input shaft, input shaft bearing, synchronous pulley, synchronous belt, positioning ring, positioning shaw, wheel cover, output shaft, body, etc. The feature is that the synchronous pulley is supported on the eccentric bearing of the input shaft, the synchronous belt is bonded with the positioning ring and fixed on the body. The number of teeth of the pulley is less than one to several teeth of the synchronous belt. It is located in the synchronous belt and intermeshes with each other, thus driving the synchronous pulley to roll along the inner circumference of the synchronous belt. The output shaft rotates through the output mechanism. It is simple and reliable, compact, light, balanced and silent. Its transmission efficiency is over 95%. Its cost is less than that of the existing ones. Cycloid needle wheel and worm drive are reduced by 1/3 to 1/2. The synchronous belt does not need lubrication. It is easy to replace and has longer service life. It is widely used in mechanical transmission collar with large deceleration ratio (including precision without backlash). Domain.
