Model utility content

Main purpose of the present utility model is to improve the some problem that existing Timing Belt exists, provide a kind of can effectively waterproof, Timing Belt that damping performance is good.

For reaching above object, the technical solution adopted in the utility model is: a kind of Timing Belt, comprise Timing Belt body and be equidistantly arranged at inside Timing Belt body Timing Belt tooth, Timing Belt body comprises the packed layer, buffer layer and the stretch-resisting layer that are superposed successively by outside to inner side, Timing Belt tooth is connected with stretch-resisting layer, the cross section upper surface of packed layer is the circular arc of outwardly convex, and packed layer outer surface is coated with drainage blanket, in stretch-resisting layer, Timing Belt length direction is provided with core rope.Because the cross section upper surface of packed layer is the circular arc of outwardly convex, rainwater etc. are not easily assembled on Timing Belt, and packed layer outer surface is coated with drainage blanket, therefore rainwater etc. generally down can drip along circular arc, thus solve Timing Belt waterproof problem; The setting of buffer layer is advantageously in the smooth running of line belt; In stretch-resisting layer, Timing Belt length direction is provided with core rope, core rope can effectively increase Timing Belt bending resistance, prevents tensile buckling, extends the working life of Timing Belt.

Preferably, the material of packed layer is nylon cloth, and the width of packed layer bottom is greater than the width of buffer layer and stretch-resisting layer.Because nylon cloth intensity is high, rebound elasticity is good, wear-resisting, further increases the performance of Timing Belt, and the bottom width of packed layer, wider than the width of buffer layer and stretch-resisting layer, decreases buffer layer and stretch-resisting layer by moistening possibility, indirectly maintains the smooth operation of belt wheel.

Further, the material of buffer layer is yielding rubber composition.Buffer layer is arranged in the middle of packed layer and stretch-resisting layer; be subject to external impacts or Timing Belt runnability poor time, buffer layer has the effect slowing down vibrations, protects effective, the smooth running of whole system; and yielding rubber composition is one preferably vibration-absorptive material, be suitable for buffer layer.

It is worth mentioning that, stretch-resisting layer and Timing Belt tooth one-body molded, stretch-resisting layer is glass fibre with synchronous toothed material.Make band tooth difficult drop-off like this, add the bending resistance of Timing Belt main body, anti-pressure ability, make Timing Belt wear resistance, toughness is greatly improved, it is high, lightweight and extend minimum all kinds of feature that glass fibre material has intensity concurrently, is suitable for stretch-resisting layer and Timing Belt tooth.

In addition, core rope is 12, and is uniformly distributed along the width direction of stretch-resisting layer.The setting of many core ropes, greatly strengthen the ability of Timing Belt stretch-proof distortion.

Compared with prior art, the utility model has the advantage of: by the optimal design to Timing Belt, the drainage blanket that surface increases on the one hand makes Timing Belt have good waterproof efficacy, arranging of buffer layer effectively can improve damping property on the other hand, the global optimization structure of Timing Belt, makes its working life, stability etc. significantly increase.
