GREASE PHYSICAL PROPERTY MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2021076491
Kind Code:
A
Abstract:
To provide a device capable of measuring the physical property of a used grease in a rolling bearing at a place apart from the rolling bearing.SOLUTION: A physical property measuring device 10 comprises: a flow pipe 11 in which a grease discharged from a rolling bearing flows; a reservoir implement 12 that has an introducing port 23, a reservoir chamber 22, and a discharge port 24 of the grease; a penetration mechanism 13 that has a piston 41 and a driving portion 42 reciprocating the piston 41, and penetrates the piston into the grease in the reservoir chamber 22; and a measuring instrument 14 measuring flow resistance generated when the piston 41 penetrates the grease in the reservoir chamber 22. The piston 41 can reciprocate in a first direction penetrating into the grease in the reservoir chamber 22 and a second direction opposite thereto. The reservoir implement 12 has a regulating portion 25 that regulates the movement of the piston 41 in the second direction. The physical property measuring device 10 further comprises a load reducing member 73 that reduces a load of the driving portion 42 when the piston 41 reaches the regulating portion 25 or immediately before reaching.SELECTED DRAWING: Figure 1
