Abstract
The application provides a device capable of exerting axial tension on a lubricating oil pump, comprising: a support connected with a pump shaft of the lubricating oil pump; a nut arranged on the pump shaft, the nut being used for locking the support; an outer sleeve comprising a step, the outer sleeve being sleeved on the support; a spring, one end of the spring being in contact with the step, the other end of the spring being in contact with a large circular ring end surface of the support; and a motor comprising a driving connection shaft, wherein the driving connection shaft is capable of being connected with the outer sleeve and the support. The device provided by the application can exert axial tension on the lubricating oil pump during a test, so that the lubricating oil pump can be more fully and comprehensively tested, and the safety and reliability of the lubricating oil pump in subsequent use are improved.
