这种同步带轮是德国BRECO做出来的，目前国内很多的同步带厂家也在做，实际工作中没用过，看样本说是向心性比较好，不会跑偏。
1.BRECO BATK加红胶同步带特点：
1. 专利弧形齿的基础上加一体导条结构，传动高度精确，防止同步带跑偏
2. 背部红胶高耐磨，可输送金属物品，寿命长。
3. 同步带轮无需挡边
4. BRECO BATK10同步带拥有接驳带和环形无缝带
2.特点（英文）
The special characteristics
• Increased tooth load resulting from the tooth curve
• Clearly reduced running noise due to a time elongated tooth mesh
• Higher power transmission precision and lower vibration tendency due to a reduced
polygon effect
• The BAT is self-guiding in the preferred running direction, no flanges are required
• The BATK is self-guiding in both running directions due to the integrated guiding track making flangesobsolete
• Length constant belts due to the application of high
tensile steel cord tension members
3.月牙齿同步带介绍
New profile shapes result in improved performance features“, this comment often describes the development possibilities of polyurethane timing belts. The curved tooth based on the proven AT profile forms the basis for the new BRECO®and BRECOFLEX® timing belts with curved teeth.
The unique curved teeth guarantee notably improved transmission and running properties.
On the one hand the BAT tooth has an increased load bearing capacity, on the other hand it does not abruptly run into the pulley gap but perfectly timed.
Both features combined lead to an increased performance, clearly reduced running noise as well as a higher transmission precision and a lower vibration tendency.
The belt centers itself on the pulleys in the stated preferred running direction due to the curved shape of the tooth which produces the self-guiding effect.
The BATK timing belt has ensued from the BAT timing belt.
Compared to the BAT the BATK is provided with a guiding track resulting in a timing belt self-guiding in both runningdirections.
