Abstract:
A rotary seal test machine comprising:a motor; a test shaft driven by the motor; a canister defining an enclosure and having inner and outer side walls with opposing and aligned inner wall and outer wall bores; said test shaft extended from said motor and into the canister through said inner wall bore; a housing adapter fitted to said outer wall bore and defining a secondary bore configured to duplicate a bore in which a defined seal specimen is to provide a sealing engagement surrounding a defined rotary shaft; said test shaft extended through said secondary bore and at the point of being extended through said secondary bore provided with a circumferential configuration simulating said defined rotary shaft, and said defined seal specimen surrounding said circumferential configuration; a contaminant contained in the canister enclosure and directed onto said shaft and seal specimen within said enclosure, said shaft protruded through said outer wall exposed for detection of contaminants leaking past the seal; and an actuator assembly connected directly to the shaft and actively imparting controlled displacements to the shaft to simulate changes in axial and lateral displacements applied to said defined shaft during operation of said rotary seal test machine.
