Description
Technical Field
[0001] The utility model belongs to the field of bearing roller measurement, and particularly relates to a measuring seat for measuring the height of rollers. Background Technique
[0002] Wind power bearings are precision mechanical parts, and their main function is to support the wind turbine rotor and enable it to rotate smoothly, thereby converting wind energy into mechanical energy. Wind power bearings are composed of four parts: inner ring, outer ring, cage and rollers. The processing accuracy of the rollers plays an important role in the normal operation of the bearings, and the accuracy requirements for the rollers are also very high. During the process of machining wind power bearing rollers, in order to ensure that each process is carried out strictly according to the process and control the dimensions and grinding amounts, the rollers need to be measured multiple times.
[0003] The height of the roller is an important factor affecting the mechanical bearing capacity. The higher the roller height, the greater the bearing capacity of the bearing; however, as the roller height increases, the contact area will gradually become larger, which will affect the friction coefficient and wear degree of the bearing; the size of the roller height also has a great impact on the rotational stability of the bearing; when the bearing rotates, phenomena such as shaking and jitter will occur; selecting rollers with appropriate height can reduce these phenomena and improve the motion state of the bearing.
[0004] When measuring the roller height, generally a measuring seat is set on the workbench, and the measuring seat can play a stable supporting role; in the prior art, the measuring seat is generally a circular base with a groove; but in the actual use process, the contact surface between the lower end of the roller and the measuring seat is generally arc-shaped, and when the roller is placed, the perpendicularity of the roller is likely to have a certain deviation, thus affecting the measurement accuracy and resulting in inaccurate measurement results. Content of the Utility Model

[0019] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0020] The following is combined with the attached Figures 1-5The specific embodiments of the present utility model will be further elaborated in detail: A measuring base for measuring the height of a roller includes a measuring base 1, a roller 2, and a micrometer 5. The lower end of the measuring base 1 is a circular base 11, and an arc-shaped groove 12 is provided on the upper end surface of the base 11; on one side of the upper end surface of the base 11, there is an arc-shaped boss 13, and an arc-shaped surface 14 is provided on the inner side wall of the arc-shaped boss 13; the size of the arc angle of the arc-shaped boss 13 should be such that it is convenient to pick up and place the roller 2 and can also provide support for the roller 2. In this embodiment, the arc angle is 90°; the roller 2 is cylindrical, and an arc chamfer 23 is provided between the rolling surface 21 and the lower end surface 22 of the roller 2; when the roller 2 is placed on the measuring base 1, the arc chamfer 23 of the roller 2 fits with the arc-shaped groove 12 of the base 11, and the arc chamfer 23 is adapted to the arc-shaped groove 12; in the actual application process, there are many types of rollers 2. In this example, the upper and lower end surfaces of the roller 2 are flat, the height of the base 11 of the measuring base 1 is equal to the vertical height of the arc chamfer 23 at the lower end of the roller 2. After the roller 2 is placed, the lower end surface of the roller 2 fits with the upper end surface of the workbench 3; when the upper and lower end surfaces of the roller 2 are convex surfaces, the lower end surface of the roller 2 and the upper end surface of the workbench 3 are in contact at a point; it is also possible to increase the height of the base 11 of the measuring base 1. After the roller 2 is placed, the lower end surface of the roller 2 does not fit with the upper end surface of the workbench 3; the rolling surface 21 of the roller 2 fits with the arc-shaped surface 14 of the base 11, and the rolling surface 21 is adapted to the arc-shaped surface 14; in actual application, when the roller 2 is placed on the measuring base 1, the rolling surface 21 of the roller 2 fits with the arc-shaped surface 14, which can prevent the roller 2 from tilting and causing perpendicularity errors; it can also improve the stability of the roller 2 during measurement and prevent the roller 2 from tilting due to accidental force during the operation process; the roller 2, the arc-shaped groove 12, and the arc-shaped surface 14 are coaxial; the axis of the arc-shaped groove 12 of the measuring base 1 is coaxial with the axis of the arc-shaped surface 14. When the roller 2 is placed on the measuring base 1, the axis of the roller 2 coincides with the axis of the roller 2 and the arc-shaped groove 12 to prevent measurement errors; the measuring base 1 is placed on the upper end surface of the workbench 3. At this time, the axes of the roller 2, the arc-shaped groove 12, and the arc-shaped surface 14 are perpendicular to the upper end surface of the workbench 3; a bracket 4 is provided on the upper end surface of the workbench 3, and a micrometer 5 is provided on the bracket 4. The front end of the measuring head of the micrometer 5 contacts the upper end surface 24 of the roller 2; the axis of the roller 2 is parallel to the axis of the measuring head of the micrometer 5; thus, the accuracy of the measuring head of the micrometer 5 when moving and measuring on the upper end surface 24 of the roller 2 can be ensured.
[0021] The usage process of the present utility model is as follows: First, place the measuring base 1 on the upper end surface of the workbench 3, and place a standard roller 2. When placing, it should be ensured that the arc chamfer 23 of the roller 2 fits with the arc-shaped groove 12 of the base 11, and the rolling surface 21 of the roller 2 fits with the arc-shaped surface 14 of the base 11; then make the front end of the measuring head of the dial indicator 5 on the bracket 4 contact with the upper end surface 24 of the roller 2, and make the axis of the roller 2 parallel to the axis of the measuring head of the dial indicator 5; after the placement is completed, perform dial calibration; after the calibration is completed, remove the standard roller 2, place the roller 2 to be measured, and perform measurement; after the measurement is completed, if measurement is required again, remove the roller 2 that has been measured, and repeat the above steps.
