Description

Technical Field

[0001] The utility model relates to the technical field of motor type test equipment, in particular to a vibration protection device for a motor type test sensor. Background Art

[0002] When the motor is undergoing type test, the torque detection sensor used is connected to the test machine and the standby test machine at both ends respectively. Since the torque detection sensor cannot be 100% coaxial with the test machine and the standby test machine, vibration will be generated at the connection between the test machine, the standby test machine and the sensor when the motor is being tested. The commonly used method is to set a diaphragm at the connection to reduce some of the vibration. However, after long-term operation, the vibration generated at the connection will still cause damage to the precision components inside the sensor, resulting in sensor failure. If the sensor fails, it usually needs to be returned to the factory for repair, which increases the repair cost and time cost and reduces the experimental efficiency. Utility Model Content

The vibration between the sensor component and the test machine and the standby machine is reduced by the shock-absorbing diaphragm component. The two vibration reduction protection components are provided, so that the generated vibration can be transferred to the base, and the vibration problem between the sensor component and the test machine and the standby machine is further reduced, thereby achieving a double shock-absorbing effect, reducing the damage problem of the vibration generated by the experiment to the sensor, reducing the failure rate and maintenance frequency, and enhancing the reliability of the experimental results.
