Measuring Wrapped Bushings: Inspection Methods

Wrapped bushings, also known as sleeve bearings or plain bearings, are an essential component in many types of machinery. It’s important to periodically inspect these bushings for wear and damage to ensure optimal performance. Here are some common inspection methods for measuring wrapped bushings:

1. Pressure Test: The pressure test inspection method involves using two semicircular inspection molds and a calibration mandrel to calibrate the zero position. The bearing slit is then placed on top of the inspection mold, and the two mold halves are brought together with an inspection load (Fch). The reading device measures the distance that the inspection mold moves down, which can be used to assess the condition of the bushing.

2. Ring Gauge Testing Method: The ring gauge testing method uses through and stop ring gauges. The bushing is pushed in and passed through the through ring gauge by hand (maximum force of 250N). Under the same force, the stop ring gauge cannot be entered. Note that in some cases, such as if the wrapped bushing is not round or if the seam is too large, the inspection accuracy may be affected.

3. Tape Measure: For larger wrapped bushings, a tape measure can be used to measure the outer diameter. To do this, a measuring tape is used to follow the bearing 360° on the centerline of the bushing’s width, and sufficient tension is applied to close the opening. The measuring tape is calibrated around a positioning mandrel whose outer diameter is equal to the nominal outer diameter of the bushing (Do). The indicating device is placed on the free end of the measuring tape and adjusted to the calibrated size. After the bushing inspection is completed, the reading of the circumference indicating device should be the difference between the measured value of the bushing and the calibration value of the positioning mandrel. From this, the outer diameter of the bushing can be calculated.

It’s important to note that these inspection methods require precision and accuracy. If you’re unsure of how to properly inspect a wrapped bushing, seek guidance from a qualified professional. With proper maintenance and regular inspections, wrapped bushings can help ensure optimal performance and extend the lifespan of machinery.

Choosing an Inspection Method for Bearing Inner Diameter

Proper maintenance and regular inspections are crucial to ensuring the optimal performance of bearings. When it comes to inspecting the inner diameter of bearings, there are various methods to choose from. Here are two common inspection methods for bearing inner diameter:

1. Plug Gauge Testing Method: The plug gauge testing method involves pressing the rolled bearing into the H7 median ring gauge and using a plug gauge to detect the inner diameter of the bearing. This method is relatively simple and straightforward and can provide accurate measurements if executed correctly.

2. Wall Thickness Micrometer Detection Method: The wall thickness micrometer detection method involves using a wall thickness micrometer to detect the wall thickness of the bearing and indirectly calculate the bearing inner diameter. It’s important to note that according to DIN1494-2, the bearing wall thickness and inner diameter cannot be marked on the drawing at the same time.

Choosing the appropriate inspection method depends on factors such as the type of bearing and the specific requirements of the machinery. It’s important to follow the manufacturer’s guidelines or seek guidance from a qualified professional when selecting an inspection method to ensure accurate and reliable results.

Self-Lubricating Wrapped Bearings and Bushings: Inspection Methods for Inner and Outer Diameter

Self-lubricating wrapped bearings and bushings are an essential component in many types of machinery, providing support to rotating shafts and reducing friction between moving parts. Proper maintenance and regular inspections of these bearings and bushings can help ensure optimal performance and extend the lifespan of machinery. Here are some inspection methods for measuring the inner and outer diameter of self-lubricating wrapped bearings and bushings:

1. Outer Diameter: To measure the outer diameter of a self-lubricating wrapped bearing or bushing, a tape measure can be used to measure the circumference. Use a measuring tape to follow the bearing or bushing 360° on the centerline of the bearing or bushing’s width, and apply sufficient tension to close the opening. The measuring tape is calibrated around a positioning mandrel whose outer diameter is equal to the nominal outer diameter of the bearing or bushing. The indicating device is placed on the free end of the measuring tape and adjusted to the calibrated size. After the inspection is completed, the reading of the circumference indicating device should be the difference between the measured value of the bearing or bushing and the calibration value of the positioning mandrel. From this, the outer diameter of the bearing or bushing can be calculated.

2. Inner Diameter: To measure the inner diameter of a self-lubricating wrapped bearing or bushing, the plug gauge testing method can be used. Press the rolled bearing or bushing into the H7 median ring gauge and use a plug gauge to detect the inner diameter of the bearing or bushing. Another method is the wall thickness micrometer detection method, which involves using a wall thickness micrometer to detect the wall thickness of the bearing or bushing to indirectly calculate the bearing or bushing’s inner diameter. Check the wall thickness in at least 3 radial positions.

Checking and Measurement Methods for Thrust Pieces, Plain Bearings, and Wrapped Bearings

Proper maintenance and regular inspections are crucial to ensuring the optimal performance and lifespan of thrust pieces, plain bearings, and wrapped bearings. Here are some checking and measurement methods for these components:

1. Thrust Piece Measurement Method: In addition to the thickness tolerance, the parallelism of the gasket is equally important for the service life of the gasket and the wear part. We use a more effective inspection method to detect the parallelism of the gasket, and let the gasket pass through two parallel blocks by its own weight. Of course, the parallel block must be larger than the specification of the gasket itself.

2. Plain Bearing Measurement Method: To measure the size and fit of plain bearings, the plug gauge testing method can be used. Press the rolled bearing into the H7 median ring gauge and use a plug gauge to detect the inner diameter of the bearing. Another method is the wall thickness micrometer detection method, which involves using a wall thickness micrometer to detect the wall thickness of the bearing to indirectly calculate the bearing’s inner diameter. Check the wall thickness in at least 3 radial positions.

3. Wrapped Bearing Measurement Method: To measure the size and fit of wrapped bearings, a tape measure can be used to measure the circumference. Use a measuring tape to follow the bearing 360° on the centerline of the bearing’s width, and apply sufficient tension to close the opening. The measuring tape is calibrated around a positioning mandrel whose outer diameter is equal to the nominal outer diameter of the bearing. The indicating device is placed on the free end of the measuring tape and adjusted to the calibrated size. After the inspection is completed, the reading of the circumference indicating device should be the difference between the measured value of the bearing and the calibration value of the positioning mandrel. From this, the outer diameter of the bearing can be calculated.

Choosing the appropriate checking and measurement methods depends on factors such as the type of component and the specific requirements of the machinery. It’s important to follow the manufacturer’s guidelines or seek guidance from a qualified professional when selecting a checking or measurement method to ensure accurate and reliable results.

Measuring Methods for Dimensional and Running Accuracy of Wrapped Bearings

Proper measuring of the dimensional and running accuracy of wrapped bearings is essential for ensuring optimal performance and longevity of machinery. Here are some key considerations when selecting measuring methods for these components:

1. The Free State of the Wrapped Sleeve: The wrapped sleeve is not a so-called cylinder in the free state due to the gap. Therefore, when measuring the outer diameter and inner diameter of the wrapped sleeve, it is important to consider the gap.

2. Press Fitting the Shaft Sleeve: When the wrapped shaft sleeve is press-fitted to the bearing seat, the gap will be tightly closed due to the interference fit. This tight fit ensures that the entire shaft sleeve fits tightly with the bearing seat, and the inner diameter/outer diameter cannot be accurately measured.

3. Special Gauge for Measuring: To accurately measure the outer diameter and inner diameter of the wrapped shaft sleeve, the shaft sleeve must be pressed into a special gauge in advance to allow the gap to be closed before measurement. This gauge ensures that the sleeve is in the correct position and allows for accurate measurements of the dimensions and running accuracy of the sleeve.
