Abstract

The invention discloses a method and a device for quickly testing a low temperature torque and similar viscosity of oil, and aims to solve the problems of high cost and long test period for testing the low temperature torque and the similar viscosity of the oil. According to the method, the device for testing the low temperature torque and the similar viscosity of the oil is used as a tester. The method comprises the following steps of: (a) preparing a test; (b) treating at low temperature; (c) testing; and (d) judging a test result. The invention also provides the device for testing the low temperature torque and the similar viscosity of the oil. According to the method and the device, a complicated test technology is converted into a detection method suitable for production enterprises; the detection method is quick, and is easy to implement; and a detection device is low in cost and easy to manufacture. By using the method and the device, data of corresponding products can be acquired and analyzed; an applicable judgment standard is constructed; and applicable oil is selected.

Description

technical field [0001] The invention relates to a testing technique, in particular to a method for quickly testing low-temperature torque and similar viscosity of grease. Background technique [0002] Both the ball pin products and the transmission pair for vehicles need to be lubricated with grease. In the returned parts of the above-mentioned products, it is sometimes found that due to the poor low-temperature performance of the grease, it is used in the case of low winter temperatures, causing the ball pin or the transmission pair to appear. Action heavy phenomenon. To solve this problem, it is necessary to test the low temperature torque and similar viscosity of the grease to determine the low temperature performance of the grease. At present, the low-temperature torque and similar viscosity tests of grease must be carried out on special testing equipment, but general manufacturers do not have the above test conditions, and usually outsource the testing of the grease to...
