All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a method for monitoring the working temperature of an oil-cooled motor includes the following steps: step one, motor test: setting each test group, testing motors in each test group, and collecting test parameters corresponding to each test group;
in a specific embodiment, the motors in each test group are tested as follows: a1, acquiring preset oil output and preset oil output speed of oil outlets corresponding to the motors in each operation information from a database, selecting each motor with the same specification as each test group, and respectively distributing each operation information to each test group to obtain operation information corresponding to the motors in each test group;
it should be noted that the motor specification includes model, power, etc.; the operation information includes motor rotation speed, motor torque, and the like.
A2, arranging monitoring points on the motors of the test groups, installing temperature sensors on the monitoring points in the motors of the test groups, further operating the motors of the test groups according to corresponding operation information of the motors under preset environment temperature, and arranging monitoring time points according to preset time intervals in the operation process, so that the temperature of the monitoring points in the motors of the test groups corresponding to the monitoring time points is collected through the temperature sensors of the monitoring points in the motors of the test groups and used as test parameters corresponding to the test groups, and the motors of the test groups are tested.
Step two, test parameter analysis: based on the test parameters corresponding to the test groups, calculating a temperature qualified value and a temperature stable value corresponding to the test groups, and further screening out each temperature unqualified test group and each temperature unstable test group;
in a specific embodiment, the calculating the temperature fit value and the temperature stability value corresponding to each test group specifically includes the following steps: the temperature corresponding to each monitoring point in the motor in each test group at each monitoring time point is recorded asWhere i denotes a number corresponding to each test group, i=1, 2, & gt, n, j denotes a number corresponding to each monitoring point, j=1, 2, & gt, m, t denotes a number corresponding to each monitoring time point, t=1, 2, & gt, p;

In another specific embodiment, the screening of each temperature failure test group and each temperature instability test group is performed as follows: comparing the temperature qualified value corresponding to each test group with a temperature qualified value threshold stored in a database, and if the temperature qualified value corresponding to a certain test group is smaller than the temperature qualified value threshold, taking the test group as a temperature disqualified test group, thereby obtaining each temperature disqualified test group;
comparing the temperature stability value corresponding to each test group with the temperature stability value threshold stored in the database, and if the temperature stability value corresponding to a certain test group is smaller than the temperature stability value threshold, taking the test group as a temperature instability test group, thereby obtaining each temperature instability test group.

when the oil outlet amount of the oil outlet hole increases, the flow rate and the cooling effect of the oil are increased.
