Shanghai polyurethane elastic sleeve

The polyurethane elastic sleeve is compressed and deformed. Because the thickness of the elastic sleeve is thin, the volume is small, and the elastic deformation is limited, although the elastic sleeve pin coupling can compensate the axis displacement and elasticity, the allowable compensation amount for the axis displacement is less. The elasticity is weak.

The polyurethane elastic sleeve relies on the locking force of the pin group to generate the frictional torque on the contact surface, and compresses the rubber elastic sleeve to transmit the torque.It is suitable for small and medium power shafting transmissions with good rigidity of the installation base, high centering accuracy, low impact load, and low vibration reduction requirements.Polyurethane elastomer is a new type of polymer synthetic material between rubber and plastic. It has both the high strength of plastic and the high elasticity of rubber.

Features of polyurethane elastic sleeve:

1. Wide range of hardness.It still has the elongation and resilience of rubber under high hardness.The hardness range of polyurethane elastomer is Shore 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. Oil resistant.Polyurethane elastomer is a kind of strong polar polymer compound, and it has little affinity with non-polar mineral oil, and it is hardly corroded in fuel oil and machine oil.

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. Radiation resistance.Polyurethane has good radiation resistance, and still has satisfactory performance under 10-10 Ge radiation dose.

9. It has good mechanical processing performance.
