Motor Load Reduction Device for Endurance Test Mechanism of Gas Spring

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor load reduction device in a durability test mechanism of a gas spring. The gas spring has a durability for testing the durability of the gas spring by installing a gas spring to perform a telescopic movement by a predetermined value. In the test mechanism, the motor (10) for providing the driving force in the test mechanism, the sleeve (13, 14, 15), which is formed integrally with the motor shaft (11) of the motor (10) and oscillates Limiter switches 50 (50a, 50b, 50c) and the sleeves (13, 14, 15) installed on the support 60 to drive the motor 10 when the sleeves (1, 14, 15) contact Weights 37, 38 and 39, which are connected to the arms 21, 22 and 23 formed integrally and oscillate, are installed on the support 27 so that the motor 10 is in contact with the weights 37, 38 and 39. Limit switch 40 (40a, 40b, 40c) for driving stop and the lower portion is fixed to the arms (21, 22, 23) It includes a length adjusting member (24, 25, 26) for installing the gas spring 34 in the formed protrusions, the swinging motion of the sleeve (13, 14, 15) for the stretching movement of the gas spring (34) When the load generated in the motor 10 can be reduced.
