Preferably, the material of the elastic retainer ring 5 is 65Mn, and at the lowest ambient temperature of a polar region drilling machine of-50 ℃, when the heat treatment process is improper, cold-brittle transition can occur at the low temperature, and the original elastic property is lost; in mechanical transmission, the use requirement of the check ring is that the main performance is elastic performance; according to the elasticity theory, the spring steel 65Mn material has the best elasticity performance when the hardness is 42-45 HRC; in order to ensure the low-temperature elastic property of the retainer ring, the process for treating the material comprises the following steps: the heat treatment process of quenching and tempering is carried out by combining the following heat treatment process with the device for treatment, and then the optimal process is determined.

The first embodiment is as follows:

putting the installed elastic retainer rings 5 into a quenching furnace, heating to 820 ℃, preserving heat for 2 hours, and discharging from the furnace for oil cooling; putting the cooled elastic retainer rings 5 into four groups into different tempering furnaces, and respectively heating the four groups to 440 ℃, 460 ℃, 480 ℃ and 500 ℃ for tempering; the test results are given in the following table:

example two:

putting the installed 5 rings of elastic check rings into a quenching furnace, heating to 840 ℃, preserving heat for 2 hours, and discharging from the furnace for oil cooling; the cooled elastic retainer rings 5 are divided into four groups and put into different tempering furnaces, and the four groups are respectively heated to 440 ℃, 460 ℃, 480 ℃ and 500 ℃ for tempering. The test results are given in the following table:

according to the first and second analysis embodiments, the reason why the hardness of the retainer ring is insufficient is mainly that the parts are stacked by the tool frames, so that the section thickness of the actual furnace charging of the parts is increased. Heating at 820 ℃ and 840 ℃ does not ensure sufficient hardenability of the material, and it is necessary to increase the hardenability by increasing the quenching temperature.

Example three: putting the installed elastic check rings 5 into a quenching furnace, heating to 860 ℃, preserving heat for 2 hours, and discharging from the furnace for oil cooling; the cooled elastic retainer rings 5 are divided into four groups and put into different tempering furnaces, and the four groups are respectively heated to 440 ℃, 460 ℃, 480 ℃ and 500 ℃ for tempering. The test results are given in the following table:

the reason that the hardness is higher at 440 ℃ and 460 ℃ in the third analysis is because the tempered tissue is not completely transformed; the reason that the tempering hardness at 500 ℃ is lower is that the tempered tissue is aggregated and grown.

By combining the test analysis, the optimal heat treatment process of the elastic retainer ring is as follows: heating at 860 deg.C for 2 hr, quenching and tempering at 480 deg.C for 2 hr.
