For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Other purposes, features and advantages of the utility model will become apparent from the following detailed description. However, it should be understood that the detailed description and specific embodiments (although representing specific implementations of the utility model) are given for illustrative purposes only, because after reading the detailed description, various changes and modifications made within the spirit and scope of the utility model will become apparent to those skilled in the art.

[0025] like Figure 1 and Figure 2 As shown, Figure 1 This is a cross-sectional view of an anti-sway sleeve device for a transmission shaft according to the utility model along the axial direction. Figure 2 For the utility model Figure 1 Section view along line AA.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment of the anti-sway sleeve device for a transmission shaft of the utility model, the device comprises an anti-sway sleeve 1, the anti-sway sleeve is sleeved on the transmission shaft 3, and the anti-sway sleeve 1 is radially provided with a plurality of ( Figure 2 The radial cross sections of the threaded holes are on the same plane, and the glass ball screws 2 are screwed into the threaded holes respectively. Figure 3 As shown, Figure 3It is an enlarged view of the glass ball screw of the utility model. The glass ball screw 2 includes a spring 4 and a steel ball 5 in contact with the spring 4. The steel ball 5 protrudes from the inner opening of the threaded hole and is used to support the transmission shaft 3. By using an anti-sway sleeve to cover the transmission shaft and providing a threaded hole on the anti-sway sleeve, the glass ball screw is screwed in and the glass ball is used to support the transmission shaft, thereby reducing the phenomenon of the transmission shaft swinging in the working state. Moreover, the steel ball 5 is in contact with the transmission shaft 3, and when the transmission shaft 3 rotates or moves, the steel ball 5 can rotate accordingly, thereby limiting the swing of the transmission shaft 3 and reducing the impact on the transmission shaft 3.

[0027] Wherein, the anti-sway sleeve 1 can be fixed on a platform, the platform is provided with a through hole, and the transmission shaft 3 passes through the anti-sway sleeve 1 and the through hole. The platform is preferably a fixed mechanism, such as a frame in a lime kiln, a platform for loading materials, etc. The material of the anti-sway sleeve 1 can be a rigid material welded on the platform, or it can be other materials that can be fixed on the platform. The axial thickness of the anti-sway sleeve 1 along the transmission shaft 3 is preferably 100 mm, and can also be set to other values ​​as needed.

[0028] The steel ball 5 can elastically press the transmission shaft 3 during the initial setting. When the transmission shaft 3 swings, the steel ball 5 will be squeezed and subjected to the reverse force of the steel ball 5, so that the swing is restricted. Moreover, under the force of the steel ball 5, the transmission shaft 3 can be corrected and returned to its initial position.

[0029] The gap between the anti-sway sleeve 1 and the transmission shaft 3 can be 1-5mm, and the depth of the glass ball screw 2 screwed into the threaded hole is used to adjust the elastic pressure of the steel ball 5 on the transmission shaft 3. Since the gap between the anti-sway sleeve 1 and the transmission shaft 3 is small, the maximum swing range of the transmission shaft 3 is limited. Furthermore, by controlling the depth of the glass ball screw 2 screwed into the threaded hole, the elastic pressure of the steel ball 5 on the transmission shaft 3 can be adjusted, so that in different scenarios such as different material loads and different spring usage times, the appropriate screw-in depth can be selected according to actual needs to limit the swing of the transmission shaft 3.

[0030] The sum of the length of the spring 4 and the diameter of the steel ball 5 may not be greater than the length of the threaded hole, that is, the length of the glass ball screw 2 is less than or equal to the length of the threaded hole.

[0031] In one embodiment, the anti-sway shield 1 is provided with three or more threaded holes on its circumference, and the three or more threaded holes are evenly distributed. Figure 2 As shown, the anti-sway sleeve 1 is provided with four threaded holes at its circumference, the radial cross-sections of the four threaded holes are on the same plane, and among the four threaded holes at the circumference of the anti-sway sleeve, the angle between two adjacent threaded holes is 90°, that is, the anti-sway sleeve is evenly provided with four threaded holes at its circumference.

[0032] In another embodiment, the threaded holes arranged at the circumference of the anti-sway shield 1 may be unevenly distributed. For example, the anti-sway shield 1 is provided with three threaded holes at its circumference, the three threaded holes are unevenly distributed, and the angle range between two adjacent threaded holes is 100° to 130°. In other words, the sum of the three adjacent angles formed by the three threaded holes is 360°, but the three adjacent angles do not need to be equal, for example, one of the adjacent angles may be greater than 120°, and the other adjacent angle may be less than 120°. For another example, the anti-sway shield 1 is provided with four threaded holes at its circumference, the four threaded holes are unevenly distributed, and the angle range between two adjacent threaded holes is 60° to 100°. Similarly, the sum of the four adjacent angles formed by the four threaded holes is 360°, but each of the adjacent angles may be a value between 60° and 100°.

[0033] The anti-sway sleeve 1 may include at least two parts surrounding the transmission shaft. For example, the anti-sway sleeve may be divided into two parts of the same shape and size, and the two parts are combined around the transmission shaft, so as to form a structure in which the protective sleeve is sleeved on the transmission shaft. In one example, when the anti-sway sleeve device is used, since the transmission shaft is relatively long, the anti-sway sleeve 1 is divided into two halves for easy installation, and the two halves of the anti-sway sleeve are combined and fixed around the transmission shaft. Preferably, the anti-sway sleeve 1 is installed and fixed in the middle part of the transmission shaft 3, and four threaded holes are evenly distributed on the circumference of the anti-sway sleeve 1. The glass ball screws 2 are screwed into the threaded holes respectively, so that the steel balls on the glass ball screws are tightly in contact with the transmission shaft 3, and the tightness of the steel balls in contact with the transmission shaft 3 can be adjusted by adjusting the glass ball screws 1. Since the steel balls are close to the transmission shaft 3 in the circumference, four support points are formed in the radial direction of the transmission shaft 3, and the transmission shaft 3 can rotate and move up and down without swinging under the support of the steel balls.

[0034] In another embodiment of the anti-sway sleeve device for a transmission shaft of the utility model, the device comprises an anti-sway sleeve 1, the anti-sway sleeve is sleeved on the transmission shaft 3, and the anti-sway sleeve is provided with multiple layers of threaded holes along the axial direction of the transmission shaft at the circumference, each layer is provided with multiple threaded holes, and the radial cross-sections of the threaded holes of each layer are on the same plane. Among them, the axial cross-sections of adjacent threaded holes of two adjacent layers may not be on the same plane, that is, the threaded holes of different layers may be staggered, so that the steel balls 5 can exert force around the transmission shaft from all angles to limit the swing of the transmission shaft.

[0035] Figure 4 Schematic diagram of a specific application scenario of the anti-sway sleeve device for the transmission shaft provided by the utility model. Figure 4As shown, one end of the drive shaft 3 in the lime kiln is connected to the motor 9 by a coupling, and the other end passes through the lower platform 11 (40-meter platform) and is connected to the hopper 12 for conveying materials into the kiln. The drive shaft is a rotating body with low speed and few supports, and is about 4 meters long.

[0036] The lower platform 11 is provided with a through hole, the diameter of which is larger than the diameter of the transmission shaft, and the transmission shaft passes through the through hole to connect to the hopper below.

[0037] The motor 9 is installed between 40 and 43 meters in height. The motor 9 drives the transmission shaft 3 and the hopper 12 to rotate (slowly) while adding materials. Two guide rails 10 are provided on both sides of the motor 9, connecting the lower platform 11 and the upper platform 6 (43-meter platform), and two guide sleeves 7 are installed along the guide rails 10.

[0038] The drive shaft rotates 360° under the drive device, and the drive shaft 3 and the hopper 12 move up and down on the guide rail. Since the materials are stones of different sizes (less than 40 cm), the material is unevenly piled during the feeding process, and the uneven weight around the hopper causes the drive shaft 3 to swing with the hopper 12 during the rotation process. In addition, the drive shaft is long, and the swing amount of the hopper is obvious.

[0039] In the utility model, an anti-swaying sleeve device 8 is fixedly arranged on the lower platform 11, and the transmission shaft 3 passes through the anti-swaying sleeve and the through hole. By screwing in the glass bead screw, the glass bead is used to support the transmission shaft to limit the swing of the transmission shaft.

[0040] The anti-sway shield may specifically include the implementation method described in any of the above embodiments and any of the implementation methods thereof.

[0041] The above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the scope of protection of the claims of the utility model.
