An arm 24 is rotatably supported by a hinge 25. The arm 24 has a vertical shaft 26 slidably inserted at one end thereof.
The ball 28 housed in a ball holder 27 provided at the lower end of the vertical shaft 26 is brought into contact with the solid lubricating film 21, and the ball 28 is pressed against the solid lubricating film 21 by the vertical load W attached to the upper end of the vertical shaft 26.

It was a lubricating film and did not evaluate the film life of a rolling element (roller) itself actually used for a bearing or the like. Also, in the method of manufacturing a bearing incorporating a roller with a solid lubricating film formed and evaluating the life of the roller by rotating the inner ring or outer ring, many samples of the roller with the solid lubricating film formed are required, In addition to the necessity of an inner ring, an outer ring, and a retainer for accommodating the rollers, the frictional factors of these components are added and measured, and the solid lubricating film itself is not evaluated. The present invention provides an apparatus in which the life of a solid lubricating film itself formed on a roller is evaluated by a single roller, and the evaluation can be easily performed with a small number of samples.

The holding member attached to the end of the load shaft is improved so that it does not come into contact with the surface of the solid lubricant film to be measured, and the sample is pressed against the rotating disk surface with a constant load. The sample is rolled, and the change in the frictional force between the sample and the disk is detected to evaluate the life of the solid lubricating film. When the solid lubricating film is formed of molybdenum disulfide, the atmospheric humidity at the time of evaluation is maintained at 25%, preferably 17% or less.

In this manner, the sample is held in contact only with the shoulders on both sides of the roller, and the sample is pressed against the disk with a constant load. The sample is rotated by the rotation of the disk, and the arm passing through the load axis is swung around the hinge with the displacement of the load axis due to the friction between the disk and the sample. The load cell detects the point at which the friction force increases and the friction force suddenly increases via the arm, and the life is evaluated based on the friction distance calculated from the rotation speed of the disk and the radius of the ball position.

If the sample is brought into contact with the sample via the interface, the influence of friction by the holding member can be reduced. It is preferable that at least a portion of the holding member that contacts the sample and the ball member are made of a resin material to reduce friction.

The solid lubricating film 2 on the outer peripheral surface to be measured is held so as not to be in contact with the holding member 5 and is pressed against the disk 10 by being brought into contact with the shoulder portion 1a at two places. Therefore, the sample 1 which was given a constant load by the weight 4 and pressed against an appropriate radial position of the disk 10
Rolls on the disk 10 as the disk 10 rotates, but since the sample 1 is held in contact with only the ball 5c, the friction between the sample and the ball and between the ball and the holding frame is small and should be almost ignored. Can be made, disk 1
The arm 6 swings around the hinge 8 in accordance with the frictional force between 0 and the lubricating film surface of the sample 1, and the load cell 9 measures the frictional force. The change in the frictional force is monitored, and the point at which the solid lubricating film 2 breaks and the frictional force with the disk 10 sharply increases is measured to evaluate the life.

The holding frame 5b is provided with an elliptical hole 5d whose major axis is slightly larger than the axial length of the sample 1 and whose minor axis is selected so that the shoulder of the sample 1 comes out. Therefore, when the holding frame 5b of the holding member 5 is placed over the sample 1 so as to be centered, the upper portion of the sample 1 is inserted into the elliptical hole 5d, and the edge of the elliptical hole 5d is positioned on the shoulder 1a of the sample 1.

る。The friction characteristics of the molybdenum disulfide film are easily affected by the humidity in the atmosphere. The higher the humidity, the greater the friction. For this reason, FIG. 12 shows the results of preparing two lots of a sample on which a molybdenum disulfide film was formed as a solid lubricating film, and evaluating the samples of each lot by changing the humidity using the present apparatus. The sample of lot A is
As the humidity decreased from 25%, a longer life evaluation was obtained. However, in the sample of lot B, the evaluation value rapidly increased when the humidity decreased from 25%, and the difference in the lubricating film from that of lot A became clear. ing. From these results, in the evaluation of the life of the molybdenum disulfide film, no remarkable difference is observed even when the lubrication characteristics are different when the environmental humidity is 25% or more, but the difference in the lubrication characteristics becomes clear when the humidity is 25% or less. ing. Therefore, the environmental humidity is 25% or less, preferably 2%.
If the rolling distance is measured at 0% or less and the evaluation is performed, a film having a long life and a film having a short life due to a difference in characteristics between the lubricating films become clear, and the evaluation can be performed more reliably.

きる。As described above, according to the present invention, a sample is formed by forming a solid lubricating film on the outer peripheral surface of a roller which is an actual bearing rolling element or a roller prepared in the same manner. The holding member provided at the end of the solid lubricating film is held so that the surface of the solid lubricating film does not contact the holding member, so there is no influence by friction other than the contact portion between the solid lubricating film and the disk, and the roller actually used Can be evaluated with a single sample,
In addition to performing reliable evaluation, the outer ring and inner ring of the bearing are not required, so that the number of samples can be reduced by reducing the number of assembling steps.

By doing so, the effect that the friction can be further reduced and the evaluation can be made accurate can be obtained.

In addition, there is an effect that the evaluation based on the change in the lubricating film characteristics can be clearly distinguished, and the life can be more reliably evaluated.
