Description

Technical Field

[0001] This utility model relates to the field of bearing runout detection technology, specifically a runout detection device for double-row angular contact ball bearings. Background Technology

[0002] Double-row angular contact ball bearings are designed essentially the same as single-row angular contact ball bearings, but occupy less axial space. They can withstand radial loads and axial loads acting in both directions, limiting bidirectional axial displacement of the shaft or housing, with a contact angle of 30 degrees. They can provide highly rigid bearing configurations and withstand overturning moments.

[0003] These types of bearings are widely used in high-precision applications such as machine tool spindles and automotive transmissions. Excessive runout can reduce the rotational accuracy of the equipment, leading to machining errors or inaccurate data. It can also cause vibration and noise, accelerate wear, shorten equipment lifespan, and even create potential for future malfunctions. Furthermore, this testing is a core quality screening method, eliminating substandard products and ensuring that bearings put into use meet standards, thus guaranteeing the stable operation of downstream equipment.

[0004] Existing double-row angular contact ball bearing runout testing equipment has difficulty in stably fixing the inner and outer rings of the bearing during testing. The outer ring often rotates synchronously with the inner ring, which makes it impossible to accurately capture the runout phenomenon during bearing operation and affects the reliability of the test results. Utility Model Content

[0005] The purpose of this invention is to provide a runout detection device for double-row angular contact ball bearings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-row angular contact ball bearing runout detection device, including a base, a support mechanism on the top of the base, a bearing body on the outer ring of the support mechanism, and a positioning component on the top of the bearing body.

[0007] The support mechanism includes a drive component, a transmission component, and a support component. The drive component is disposed inside the base, the transmission component is disposed on top of the drive component, and the support component is disposed on top of the base.

[0008] The positioning component includes a lifting component, a locking component, and a limiting component. The lifting component is located at the top of the base, the locking component is located at the bottom of the lifting component, and the limiting component is located on the left and right sides of the locking component.

[0009] Preferably, the drive assembly includes a servo motor, which is fixedly connected to the base, and a drive shaft is fixedly connected to the top of the servo motor, which is rotatably connected to the top of the base.

[0010] Preferably, the transmission assembly includes a retaining sleeve, which is fixedly connected to the top of the drive shaft. A retaining strip is fixedly connected to the outer ring of the retaining sleeve. The retaining sleeve is sleeved on the inner ring of the bearing body, and the retaining strip is engaged in the inner ring of the bearing body.

[0011] Preferably, the support assembly includes a support base, which is fixedly connected to the top of the base. A ball bearing is rotatably connected to the top of the support base, and the ball bearing is slidably connected to the bottom of the retaining cylinder. A connecting bearing is fixedly connected to the inner ring of the support base, and the connecting bearing is fixedly connected to the outer ring of the drive shaft.

[0012] Preferably, the lifting assembly includes a support rod, which is fixedly connected to the four corners of the top of the base. A frame plate is fixedly connected to the top of the support rod, an electric cylinder is fixedly connected to the top of the frame plate, and a telescopic rod is fixedly connected to the bottom of the electric cylinder.

[0013] Preferably, the locking assembly includes a connecting plate, which is fixedly connected to the bottom of the telescopic rod. A sleeve is fixedly connected to the bottom of the connecting plate, and a second locking strip is fixedly connected to the inner ring of the sleeve.

A sliding cylinder is fixedly connected to the outer side of the convex plate, and the sliding cylinder is slidably connected to the outer ring of the support rod. Reinforcing rods are fixedly connected to the front and rear sides of the inner side of the convex plate.

[0015] Compared with the prior art, this utility model provides a runout detection device for double-row angular contact ball bearings, which has the following advantages: 1. This double-row angular contact ball bearing runout detection device, through its support mechanism, allows operators to simply clamp the bearing body onto the outer ring of the clamp. The support base then supports the bearing body while simultaneously driving the outer ring of the clamp via a servo motor to rotate the clamp. This allows the runout of the bearing body to be detected by rotating the inner ring while the outer ring of the bearing body remains stationary. The device is simple to operate and easy for operators to use.

[0016] 2. This double-row angular contact ball bearing runout detection device, through its positioning mechanism, allows the operator to activate the electric cylinder after the bearing body is engaged with the outer ring of the retaining sleeve. This, via the telescopic rod, moves the sleeve downwards, allowing it to engage with the outer ring of the bearing body. The retaining strip then secures the outer ring of the bearing body within the inner ring, ensuring that the outer ring remains stationary while the inner ring of the bearing body rotates. This facilitates the detection of runout during bearing operation and is simple and easy for operators to use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] This utility model provides a technical solution: Example 1: Combining Figures 1 to 4 A double-row angular contact ball bearing runout detection device includes a base 3, a support mechanism 1 on the top of the base 3, a bearing body 4 on the outer ring of the support mechanism 1, and a positioning component 2 on the top of the bearing body 4.

[0022] The support mechanism 1 includes a drive component 11, a transmission component 12, and a support component 13. The drive component 11 is disposed inside the base 3, the transmission component 12 is disposed on top of the drive component 11, and the support component 13 is disposed on top of the base 3.

[0023] The drive assembly 11 includes a servo motor 1101, which is fixedly connected to the base 3. A drive shaft 1102 is fixedly connected to the top of the servo motor 1101 and rotatably connected to the top of the base 3. The transmission assembly 12 includes a retainer 1201, which is fixedly connected to the top of the drive shaft 1102. A retaining strip 1202 is fixedly connected to the outer ring of the retainer 1201. The retainer 1201 is sleeved on the inner ring of the bearing body 4, and the retaining strip 1202 is engaged in the inner ring of the bearing body 4. The support assembly 13 includes a support base 1301, which is fixedly connected to the top of the base 3. A ball bearing 1302 is rotatably connected to the top of the support base 1301 and slidably connected to the bottom of the retainer 1201. A connecting bearing 1303 is fixedly connected to the inner ring of the support base 1301 and fixedly connected to the outer ring of the drive shaft 1102.

[0024] Furthermore, after the operator simply attaches the bearing body 4 to the outer ring of the clamp 1201, the support base 1301 can support the bearing body 4 while driving the outer ring of the clamp 1201 through the servo motor 1101 to complete the rotation of the clamp 1201. This allows the runout of the bearing body 4 to be detected by rotating the inner ring while the outer ring of the bearing body 4 remains stationary. The operation is simple and convenient for operators to use.

[0025] Example 2: See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the positioning component 2 includes a lifting component 21, a locking component 22, and a limiting component 23. The lifting component 21 is located at the top of the base 3, the locking component 22 is located at the bottom of the lifting component 21, and the limiting component 23 is located on the left and right sides of the locking component 22.

[0026] The lifting assembly 21 includes a support rod 2101, which is fixedly connected to the four corners of the top of the base 3. A frame plate 2102 is fixedly connected to the top of the support rod 2101. An electric cylinder 2103 is fixedly connected inside the top of the frame plate 2102. A telescopic rod 2104 is fixedly connected to the bottom of the electric cylinder 2103. The locking assembly 22 includes a connecting plate 2201, which is fixedly connected to the bottom of the telescopic rod 2104. A sleeve 2202 is fixedly connected to the bottom of the connecting plate 2201. The inner ring of 2202 is fixedly connected with a second retaining strip 2203. The sleeve 2202 is sleeved on the outer ring of the bearing body 4. The second retaining strip 2203 is engaged inside the outer ring of the bearing body 4. The limiting component 23 includes a protruding plate 2301. The protruding plate 2301 is fixedly connected to the left and right sides of the outer ring of the sleeve 2202. A sliding cylinder 2302 is fixedly connected to the outer side of the protruding plate 2301. The sliding cylinder 2302 is slidably connected to the outer ring of the support rod 2101. Reinforcing rods 2303 are fixedly connected to the front and rear sides of the inner side of the protruding plate 2301.

[0027] Furthermore: After the bearing body 4 is engaged with the outer ring of the retaining sleeve 1201, the operator only needs to activate the electric cylinder 2103 to drive the sleeve 2202 downward through the telescopic rod 2104, so that the sleeve 2202 is engaged with the outer ring of the bearing body 4. The retaining strip 2203 is engaged with the inner ring of the bearing body 4 to complete the fixation of the outer ring of the bearing body 4. When the inner ring of the bearing body 4 rotates, the outer ring can remain stationary, which makes it convenient for the operator to detect the runout phenomenon of the bearing body 4 during operation. The operation is simple and convenient for the operator to use.

[0028] In actual operation, when this device is used and it is necessary to perform runout detection on the bearing body 4, the operator first puts the bearing body 4 onto the outer ring of the clamping sleeve 1201, so that the clamping strip 1202 is engaged in the inner ring of the bearing body 4. Then the operator starts the electric cylinder 2103. The start of the electric cylinder 2103 drives the connecting plate 2201 to move downward through the telescopic rod 2104. The downward movement of the connecting plate 2201 drives the sleeve 2202 to move downward. The sleeve 2202 moves downward and puts itself onto the outer ring of the bearing body 4. At this time, the clamping strip 2203 is engaged in the inner ring of the bearing body 4, thus completing the fixation of the outer ring of the bearing body 4. Then, the staff can start the servo motor 1101. The start of the servo motor 1101 drives the chuck 1201 to rotate through the drive shaft 1102. The rotation of the chuck 1201 drives the inner ring of the bearing body 4 to rotate through the chuck bar 1202. At this time, the staff can observe the jumping phenomenon of the bearing body 4 during the movement.
