Description

Rotational Accuracy Detector for Extra Large Cylindrical Roller Bearings

technical field

The utility model belongs to the technical field of bearings, and mainly relates to a rotation accuracy detector of an extra-large cylindrical roller bearing. It is suitable for the detection of rotation accuracy of extra large cylindrical roller bearings and the accuracy detection of extra large bearing parts.

Background technique

In the bearing industry, the detection of the rotation accuracy of cylindrical roller bearings has long been completed by the mandrel, but for the detection of the rotation accuracy of extra-large (generally refers to bearings with an outer diameter greater than 440mm) cylindrical roller bearings, due to the difficulty of processing the mandrel Larger, higher cost and unable to meet the needs of production, so the general manufacturers often use the accuracy of parts to ensure the rotation accuracy of the finished product. There is still no domestic testing equipment for this type of bearing rotation accuracy. At the same time, at the present stage, the accuracy of extra-large bearing ring parts has many shape and position tolerances that cannot be detected by instruments, and are guaranteed by equipment, such as: vertical difference, concentricity of double raceways, etc.

Contents of the invention

The purpose of this utility model is to provide an extra-large cylindrical roller bearing rotation accuracy detector, which is used to solve the problem that the bearing industry cannot detect the rotation accuracy of extra-large cylindrical roller bearings for a long time, so that the bearing rotation accuracy can be intuitively displayed. Reflect and make an accurate judgment on the bearing accuracy level.

The purpose of this utility model can be achieved by adopting the following technical solutions: it is mainly composed of a measuring platform, a platform support, a V-shaped support, a support block and a deep groove ball bearing support, the measuring platform is fixed on the platform support, and the V-shaped support is fixed on the measuring platform. On the platform, the support blocks and deep groove ball bearing supports are evenly distributed in pairs on the measurement platform.

The measuring platform is obliquely fixed on the platform support. Three support blocks and three pairs of deep groove ball bearing supports are respectively arranged on the measurement platform, and are evenly distributed on the measurement platform, wherein the deep groove ball bearing supports are located inside the support blocks.

The utility model mainly aims to solve the detection of the rotational precision of a large batch, large size, large weight and high precision cylindrical roller bearing. It effectively detects the rotation accuracy of extra-large cylindrical roller bearings, and can intuitively reflect whether the bearing rotation accuracy meets the requirements of the standard. It can meet the detection of the rotation accuracy of super-large cylindrical roller bearings, and theoretically can also meet the detection of the rotation accuracy of super-large spherical roller bearings, providing reliable actual parameters for the judgment of the accuracy level of super-large cylindrical roller bearings. It can detect the shape and position tolerance items of extra-large bearing rings, especially the items such as curvature, vertical difference, and concentricity of double-row raceways that cannot be detected by instruments can be directly detected by this instrument.

Through actual measurement, the utility model can meet the detection of the shape and position tolerance items of the extra-large bearing ring.

Detailed ways

In conjunction with the accompanying drawings, the specific embodiments of the utility model are described.

The overall composition of the utility model is mainly composed of a measurement platform 4, a platform bracket 5, a V-shaped support 1, a support block 2 and a deep groove ball bearing support 3. The measurement platform 4 is obliquely fixed on the platform bracket 5, so that the measurement platform as a whole into a slope. The V-shaped support is fixed on the bottom of the measurement platform 4 . Three support blocks 2 and three pairs of deep groove ball bearing supports 3 are arranged above the V-shaped support on the measurement platform. inside of the block. On the measuring platform 4, the bearing under test is fixed with a V-shaped support 1, and the supporting block 2 at the bottom and the supporting deep groove ball bearing 3 are tightly connected with the measuring platform 4 through bolts, so that the inner ring or outer ring of the bearing under test can rotate freely. The hands swing to read the measured value.

The measurement platform 4 is a reference plane for measurement, which serves as an overall support and guarantees accuracy. The platform support 5 is the basis for supporting the measurement platform, and its stability and firmness ensure the accuracy of the measurement. The V-shaped support 1 fixes and limits the movement of the inner and outer rings of the tested bearing, and plays a role in positioning, ensuring that the inner and outer rings do not rotate simultaneously during measurement. The support block 2 fixes the reference plane of the fixed ring of the tested bearing in a plane and limits the rotation of the fixed ring.

The deep groove ball bearing supports the end face of the movable ring in the same plane, which reduces the friction of the ring and enables the movable ring to rotate freely.

The process of measuring the swing of the inner diameter of the bearing is described in conjunction with accompanying drawings 3 and 4. To measure the inner diameter pendulum (Kia) of the bearing, first adjust the V-shaped support block 1, which is the opening to support the outer diameter, then adjust the three support blocks 2 to support the end face of the outer ring of the tested bearing, and finally adjust the three pairs of deep groove ball bearings Support 3 so that it supports the end face of the inner ring of the bearing under test, place the measuring gauge 8 on the platform of the inner ring, the needle directly touches the inner diameter of the bearing under test, rotate the inner ring of the bearing under test, the swing value displayed on the gauge is the inner diameter swing measured value.

The process of measuring the swing of the outer diameter of the bearing is illustrated in conjunction with the accompanying drawing 5. To measure the swing of the outer diameter of the bearing (Kea), first adjust the V-shaped support block 1, which is the inner diameter of the opening support, and then adjust the three support blocks 2 to support the bearing of the tested bearing. Inner ring end face, finally adjust three pairs of deep groove ball bearing supports 3 to make it support the outer ring end face of the bearing under test, place the measuring gauge 8 on the outer ring platform, the gauge needle directly touches the outer diameter of the bearing under test, and rotate the bearing under test On the outer ring, the swing value displayed on the hands is the measured value of the outer diameter pendulum.
