Description

Technical Field

[0001] This utility model relates to a floating correction device, and more particularly to a floating bearing device suitable for high-speed motor drive shafts. Background Technology

[0002] For existing high-speed motors, the drive shaft interfaces with the device being driven. Due to high-speed operation, if the drive interface of the device has excessive tolerances, or if the device itself is not in a relatively stationary state, the drive shaft may experience non-concentric misalignment. If this deviation occurs repeatedly and is not corrected in time, it may lead to shaft breakage, affecting the lifespan of the drive shaft. Furthermore, this anomaly can easily cause abnormal noises, requiring the user to stop the machine for troubleshooting, thus affecting the normal operation of the high-speed motor.

[0003] Currently, there are also methods to reduce such misalignment by installing a correction mechanism on the drive shaft. However, commonly used correction mechanisms mainly use high-precision bearings, which are prone to self-wear when non-coaxial misalignment occurs, resulting in poor correction effectiveness. Furthermore, for high-speed motor operation, the bearing mating angle is reduced, which may lead to jamming and secondary damage to the drive shaft.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a floating bearing device suitable for high-speed motor drive shafts, making it more industrially valuable. Utility Model Content

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] like Figures 1 to 2A floating bearing device suitable for high-speed motor drive shafts includes a nested box 1, which is unique in that: a bearing assembly 2 is installed inside the nested box 1, and a through channel is provided at the position of the shaft hole of the bearing assembly 2 in the nested box 1. The drive shaft 16 of the high-speed motor can be guided through the bearing assembly 2 and can rotate synchronously with it, without causing motion interference while providing guidance. In order to reduce the amplitude of abnormal wobble that may occur in the drive shaft 16 under high-speed operation and to achieve coaxial rotation of the drive shaft 16 and the motor as much as possible to improve the running accuracy, several floating adjustment devices are connected to the through channel. Specifically, the floating adjustment device includes a receiving groove 3 distributed along the through channel, and an adjustment groove 4 is opened at the front end of the receiving groove 3. The adjustment groove 4 is connected to the through channel to provide a certain motion guidance space for the subsequent contact block to avoid jamming. During implementation, an elastic component 5 is installed in the receiving groove 3, a guide component is installed on the elastic component 5, and a contact block is installed on the contact guide component. Meanwhile, in order to prevent the guide components from accidentally coming loose during installation and to achieve stable forward and backward movement without tilting, a partition 6 is distributed between the receiving groove 3 and the adjusting groove 4. A guide hole is provided on the partition 6, through which the guide components pass.

[0036] In a preferred embodiment of this invention, the bearing assembly 2 is a ball bearing. This minimizes frictional resistance during rotation. Furthermore, even during the floating adjustment of the drive shaft 16, certain surfaces can maintain contact, preventing "free-spinning." This provides appropriate guiding assistance to the drive shaft 16, preventing "shaft slippage."

[0037] Furthermore, this invention features gaskets 7 fitted and distributed along the inner wall of the shaft hole of the bearing assembly 2. Specifically, if a greater fit with the drive shaft 16 is required, silicone gaskets 7 can be used. If a certain speed difference is required for the drive shaft 16 during use, POM gaskets 7 can be used. During implementation, silicone gaskets 7 are preferred.

[0038] Meanwhile, a base 8 is installed at the bottom of the receiving groove 3, and one end of the elastic component 5 is connected to the base 8 to achieve tail-end positioning and avoid unnecessary vibration. During implementation, the elastic component 5 can preferably be a spring. A spring with a suitable elastic coefficient can be selected according to the diameter of the drive shaft 16 and the inner diameter of the through channel, so that the pressure plate 10 always fits against the surface of the drive shaft 16 to achieve floating correction.

[0039] Looking further, the guide assembly is a guide rod 9, with a pressure plate 10 installed at its end. The pressure plate 10 contacts the elastic component 5, and a contact block is threadedly connected to the front end of the guide rod 9. This enables effective elastic transmission and ensures stable contact of the contact block. Specifically, the contact block includes a support plate 11 connected to the guide assembly, with a contact block body 12 embedded in the support plate 11. This allows for the selection of a suitable contact block body 12 based on the actual rotational speed range of the drive shaft 16, preventing high-temperature deformation and providing appropriate pressure support. Typically, a high-temperature resistant POM block is preferred.

[0040] Furthermore, to ensure the locking and positioning of the bearing assembly 2, several positioning screws 13 are connected to the nested box 1, and these screws 13 contact the bearing assembly 2. To mate with the pre-installed plate at the front end of the high-speed motor, mating plates 14 are distributed on the nested box 1, and locking screws 15 are distributed on the mating plates 14. This ensures a final screw-locking connection without any shaking.

[0041] The working principle of this utility model is as follows:

[0042] During operation, the drive shaft 16 of the high-speed motor may experience a non-concentric offset due to the wobbling of the device connected to it. At this time, the guide component, relying on the force applied by the elastic component 5, will drive the contact block to apply force to the drive shaft 16. During this process, the drive shaft 16 will first float and then return to its original concentric state.

[0043] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0044] 1. Equipped with a bearing assembly, it can limit the maximum range of movement when the drive shaft is not concentric, thus preventing "shaft breakage" and maintaining drive stability.

[0045] 2. Equipped with a floating adjustment device, the drive shaft in a non-concentric offset state can be floated and corrected through elastic contact adjustment, so that it can be reset as soon as possible without stopping the machine for fine adjustment.

[0046] 3. Floating is achieved mechanically, without the need for electronic sensing devices, resulting in better stability and lower implementation costs.

[0047] 4. After installation, the bearing assembly can be properly limited, and there will be no abnormal shaking or resonance.

[0048] 5. It can be equipped with a docking plate to facilitate installation on high-speed motors.

[0049] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
