Polyurethane elastic sleeve

聚氨酯弹性套是受压缩变形，由于弹性套的厚度较薄，体积小，弹性变形有限，所以，弹性套柱销联轴器虽可补偿轴线位移和弹性，但轴线位移许用补偿量较少，弹性较弱。

聚氨酯弹性套是依靠柱销组的锁紧力而产生于接触面的摩擦力矩，并压缩橡胶弹性套来传递转矩。适用于安装底座刚性好、对中精度较高、冲击载荷不大、对减振要求不高的中小功率轴系传动。 聚氨酯弹性体是一种介于橡胶和塑料之间的新型高分子合成材料，它既具有塑料的高强度又具有橡胶的高弹性。

聚氨酯弹性套特点：

1、硬度范围宽。在高硬度下仍具有橡胶的伸长率和回弹性。聚氨酯弹性体的硬度范围为邵氏A10-D80。

2. High strength.Their tear strength and load-carrying capacity are much higher than general rubber under the hardness of rubber.Under high hardness, its impact strength and bending strength are much higher than plastic.

3、 。其能非常杰出，一般在0.01-0.10（cm3）/1.61km范围内，约为橡胶的3-5倍。

4、 耐油。聚氨酯弹性体是一种强极性高分子化合物，和非极性矿物油的亲和性小，在燃料油和机械油中几乎不受侵蚀。

5. Good resistance to oxygen and ozone.

6. Excellent vibration absorption performance, which can be used for vibration reduction and buffering.In the mold manufacturing industry, it replaces rubber and springs.

7. It has good low temperature performance.

8、 耐辐射性能。聚氨酯耐   射线的性能很好，在10-10戈辐射剂量下仍具有满意的使用性能。

9、 具有良好的机械加工性能。
