Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, in particular to a wheel axle capable of adaptively adjusting an axis center line and a rope saw machine transmission wheel composed of the wheel axle and the axis center line. Background Art

[0002] At present, bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Traditional bearings are fixed on the bearing seats, and the axis cannot be changed. Once the vertical position of the axis needs to be changed, only the bearing platform fixed to the bearing seat can be adjusted.

[0003] The prior art CN201710494185.X discloses a bearing seat with adjustable axis, which belongs to the field of bearing installation technology. It includes an axis seat; a mounting hole is opened in the center of the axis seat, and a bearing is installed in the axis seat mounting hole; the bearing includes an inner ring of the bearing, an outer ring of the bearing, and a rolling body installed between the inner ring of the bearing and the outer ring of the bearing; a circle of grooves is opened on the circumferential surface of the outer ring of the bearing; a plurality of adjustment bolts are arranged around the axis seat; the inner end of the adjustment bolt is connected to a top plate through a spherical pair; the top plate is in an arc shape that fits in the groove of the outer ring of the bearing; although the invention can realize the multi-directional and multi-range adjustment of the bearing axis, it still has the following problems: 1. The above design relies on manual adjustment of each bolt to change the axis position, which is not ideal for dynamic application scenarios that require frequent adjustment or real-time response. Manual adjustment is not only time-consuming and labor-intensive, but also difficult to achieve accurate and fast adjustment. In addition, in the case of one axis and multiple wheels, the tension required on each driven wheel is different, and it is impossible to adjust it individually, and it is impossible to ensure that each driven wheel is in a suitable state.

[0004] 2. The position between the existing transmission wheel and the transmission shaft is relatively fixed, and the transmission shaft can only rotate around the central axis. Therefore, after the two ends of the transmission shaft are fixed, the cutting line / saw rope sleeved on the transmission wheel can only be tensioned by an additional tensioning wheel, which increases the space occupied by the equipment. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a wheel axle that can adaptively adjust the center line of the axis and the rope saw machine transmission wheel composed of it, which can drive the piston of the hydraulic push rod to move by controlling the pressure in the hydraulic delivery chamber, and then drive the sliding sleeve connected to it to move radially along the center axis, thereby realizing faster and more accurate adjustment of the center line, and solving the problem that traditional designs are difficult to achieve individual adjustment.

[0006] The technical solution adopted by the present invention to solve its technical problem is: A wheel axle capable of adaptively adjusting the axis centerline is provided, comprising: a central axis, at least one sliding sleeve and at least one hydraulic push rod; At least one hydraulic delivery chamber penetrating the central shaft is provided on the central shaft along its axial direction, at least one mounting hole is provided on the outer circumferential surface of the central shaft along its axial direction, the mounting hole is arranged perpendicular to the axis of the hydraulic delivery chamber and is communicated with the hydraulic delivery chamber, a hydraulic push rod is provided in the mounting hole correspondingly, the sliding sleeve is sleeved on the central shaft corresponding to the hydraulic push rod and can be connected to the driving end of the corresponding hydraulic push rod, and the hydraulic push rod can drive the sliding sleeve to move axially along the mounting hole.

[0007] It should be noted that the center shaft is the core component of the entire wheel axle system. It not only provides mechanical support, but also serves as a channel for the transmission of hydraulic fluid. The hydraulic transmission chamber inside the center shaft is used as a transmission channel for hydraulic oil, so that the hydraulic oil can be transmitted to each mounting hole and act on the hydraulic push rod. The mounting hole can be used as a placement space for the hydraulic push rod, and can ensure that the hydraulic oil can enter the mounting hole from the hydraulic transmission chamber to push the hydraulic push rod, ensuring that each hydraulic push rod can synchronously respond to the pressure changes of the hydraulic system; the sliding sleeve is arranged on the outside of the center shaft and connected to the driving end of the hydraulic push rod. When the hydraulic push rod is subjected to the hydraulic action, it will push or pull the sliding sleeve to move radially along the center shaft, thereby realizing adaptive adjustment of the centerline position of the transmission wheel shaft, and improving the adaptability of the equipment to different working conditions; and because the hydraulic system is used to drive the position change of the centerline of the shaft, a control system can be added for automatic adjustment, which not only reduces the need for manual operation, but also can respond to changes in working conditions more quickly and accurately.

[0008] Preferably, the central axis includes a fixed axis and an adjusting axis, and the outer circumferential surface of the adjusting axis is symmetrically provided with parallel sliding planes along its axial direction, and the outer circumferential surface between the sliding planes is provided with a hydraulic plane, and the mounting holes are arranged on the hydraulic planes at intervals along the axial direction of the central axis, and the fixed axis is correspondingly arranged at both ends of the adjusting axis and is integrally formed with the adjusting axis, and a fixed plane is provided on the outer circumferential surface of the fixed axis corresponding to the sliding plane.

[0009] It should be noted that the adjusting shaft is responsible for cooperating with the sliding sleeve to achieve the adjustment of the axis centerline position, while the fixed shaft provides fixed support and ensures the stability of the entire system; the outer circumference of the adjusting shaft is symmetrically provided with parallel sliding planes along its axial direction, and these planes provide a stable moving track for the sliding sleeve, ensuring that the sliding sleeve will not rotate or shift during radial movement, thereby ensuring the accuracy and stability of the axis centerline adjustment; the hydraulic planes arranged between the sliding planes are used for the arrangement of the mounting holes, thereby providing a placement space for the hydraulic push rod. The existence of the hydraulic planes can ensure the accuracy and sealing of the hydraulic push rod installation. At the same time, the hydraulic components are concentrated in a specific area, which helps to simplify the structural design, improve the compactness and efficiency of the hydraulic system, and facilitate maintenance and inspection; the fixed planes arranged on the outer circumference of the fixed shaft corresponding to the sliding planes can ensure that the two ends of the center shaft can be accurately fixed on the mounting seat to prevent it from rotating or shifting during use.

[0010] Preferably, a center hole is provided in the middle of the sliding sleeve corresponding to the cross-sectional shape of the adjusting shaft, the upper and lower inner surfaces of the center hole are fitted on the sliding plane, and the radial width L of the upper and lower inner surfaces is greater than the radial width N of the sliding plane, and a positioning hole is provided on the inner wall of the center hole corresponding to the side where the hydraulic push rod extends, the sliding sleeve is connected to the driving end of the hydraulic push rod through the positioning hole, and can be moved axially along the mounting hole through the hydraulic push rod.

[0011] It should be noted that the upper and lower inner surfaces of the center hole fit on the sliding plane of the adjusting shaft. This design ensures that the sliding sleeve can only move in a straight line along the predetermined path (i.e., the sliding plane on the adjusting shaft), avoiding unnecessary rotation or tilting, thereby improving the accuracy and stability of the axis centerline adjustment; the width of the upper and lower inner surfaces of the center hole is greater than the width of the sliding plane, which provides an effective path for the movement of the sliding sleeve, enhances the stability of the sliding sleeve during movement, and reduces the risk of wear and deviation; the design of the locating hole makes the connection between the sliding sleeve and the hydraulic push rod more intuitive and simple, reduces possible errors during assembly, and improves production efficiency; since the sliding sleeve is directly connected to the hydraulic push rod, the force transmission is more direct and effective, reduces energy loss, and improves the response speed and work efficiency of the system.

[0012] Preferably, an oil filling hole is provided along the axial direction of the corresponding sliding plane on the central axis, and a lubricating oil groove and an oil outlet hole are provided on the corresponding sliding sleeve on the sliding plane. The lubricating oil groove is horizontally arranged on the sliding plane along the radial direction of the central axis, and one end of the oil outlet hole is connected to the oil filling hole, and the other end is connected to the lubricating oil groove.

[0013] It should be noted that the oil filling hole provides a channel for the lubricating oil to be transported, the oil outlet hole enables the lubricating oil to be accurately transported to the part that needs lubrication, and the lubricating oil groove is arranged radially along the center axis on the sliding plane to ensure that the lubricating oil can cover the entire sliding contact surface; the oil filling hole, the lubricating oil groove and the oil outlet hole together constitute an efficient lubrication path, ensuring that the lubricating oil can be quickly and evenly distributed to each sliding contact surface, thereby improving the lubrication efficiency of the system and reducing the friction coefficient.

[0014] Preferably, the sliding sleeves are mutually abutted and sleeved on the central shaft, and oil outlet grooves are provided on the side surfaces thereof along the radial direction.

[0015] It should be noted that multiple sliding sleeves are arranged in sequence and contact each other, that is, each sliding sleeve fits tightly with the adjacent sliding sleeves. This design ensures that each sliding sleeve will not be unnecessarily offset or rotated when moving radially along the central axis, thereby maintaining the stability and consistency of the entire system. Through the design of the oil outlet groove, the lubricating oil can evenly cover the contact surface between the sliding sleeves, reduce friction, improve the smoothness of movement, and help dissipate heat.

[0016] Preferably, the hydraulic push rod includes a piston rod, a guide sleeve and a fixed seat, the guide sleeve is arranged on the fixed seat, and the guide sleeve and the fixed seat are provided with a through hole for the piston rod to pass through along the axial direction of the guide sleeve, the piston rod is arranged in the through hole and can move axially along the through hole, the fixed seat is fixed on the sliding plane, and the guide sleeve is arranged in the mounting hole.

[0017] It should be noted that the piston rod is used to transmit the pressure of the hydraulic system. One end of the piston rod is located in the hydraulic delivery chamber, and the other end extends out and is connected to the sliding sleeve. The guide sleeve is arranged on the fixed seat, and a through hole is provided inside for the piston rod to pass through. The guide not only provides a guiding function, but also plays a sealing role to prevent hydraulic oil leakage and maintain the efficiency of the hydraulic system. The fixed seat is installed on the sliding plane to fix the guide sleeve, so that the hydraulic push rod can be firmly installed on the central axis, reducing the risk of vibration and displacement and enhancing the overall rigidity of the system; the modular design of the hydraulic push rod makes it easy to install and disassemble, simplifies the assembly process, reduces the production difficulty and technical requirements, and improves production efficiency.

[0018] A wire saw transmission wheel is also provided, comprising: at least one bearing, at least one rotating wheel, an end cover and the wheel axle capable of adaptively adjusting the axis center line as described in any one of the above; The inner ring of the bearing is fixedly nested on the outer circumferential surface of the corresponding sliding sleeve, the runner is fixedly nested on the outer ring of the bearing and can rotate synchronously with the outer ring, and the end covers are correspondingly arranged at both ends of the central axis and can seal the bearings and the side surfaces of the runner at both ends of the central axis.

[0019] It should be noted that the bearing serves as a support to ensure that the wheel can rotate smoothly around the axle. The wheel is fixedly nested on the outer ring of the bearing. Through the connection of the bearing, the wheel can achieve smooth and efficient rotational movement, while ensuring its stable position relative to the axle. The end covers are arranged at both ends of the central axis to seal the bearings and the sides of the wheel at both ends of the central axis, which not only protects the internal components, but also provides structural closure to prevent external impurities from entering the internal mechanical structure, thereby ensuring the cleanliness and reliability of the system; at the same time, it also enhances the sealing performance of the entire device to avoid lubricating oil leakage.

[0020] Preferably, the cross-section of the outer ring of the bearing is stepped, and positioning screw holes are evenly distributed on the outer step around the axis. A step ring is provided on the middle part of the rotating wheel corresponding to the outer ring of the bearing, and a locking screw hole is provided on the step ring corresponding to the positioning screw hole. The rotating wheel is fixed to the bearing through the positioning screw hole and the locking screw hole, and a wheel groove for installing a saw rope is provided on the outer circumferential surface of the rotating wheel.

[0021] It should be noted that the design of the stepped outer ring and the stepped ring not only increases the contact area between the runner and the bearing, improves the strength and stability of the connection, and ensures a tight and gap-free fit between the two, but also provides a positioning function for the installation of the runner; the cooperation of the positioning screw hole and the locking screw hole can ensure that the runner can be accurately positioned during installation, avoiding eccentricity or imbalance caused by assembly errors, thereby improving the rotation accuracy of the entire transmission system.

[0022] Preferably, a sealing groove is provided on the surface of one side of the inner ring of the runner around the axis, and a water sealing ring is provided in the sealing groove.

[0023] It should be noted that the sealing groove is designed to accommodate the water seal ring to ensure its correct installation and sealing effect. The water seal ring is usually made of wear-resistant and corrosion-resistant materials such as rubber or Teflon. The main function of the water seal ring is to prevent external moisture, dust and other impurities from entering the transmission system, and also to prevent leakage of internal lubricating media.

[0024] Preferably, an adjusting screw hole is provided on the end cover at one end of the wheel axle, and a stopper is correspondingly provided on the central axis of the other end. An adjusting bolt is provided in the adjusting screw hole. After passing through the adjusting screw hole, the adjusting bolt abuts against the side of the sliding sleeve through a wear-resistant copper pad, and tightens the sliding sleeves at both ends of the wheel axle by cooperating with the stopper.

[0025] It should be noted that the sliding sleeves at both ends of the central shaft can be tightened by adjusting the bolts to ensure that the sliding sleeves do not undergo unnecessary displacement or vibration during operation, thereby enhancing the stability of the system. The presence of the wear-resistant copper pad reduces the wear that may be caused when the adjusting bolts directly contact the surface of the sliding sleeve, thereby extending the service life of the sliding sleeve and other related components.

[0026] Beneficial effects of the present invention: The wheel axle capable of adaptively adjusting the axis centerline provided by the present invention controls the pressure in the hydraulic delivery chamber to drive the hydraulic push rod to make the sliding sleeve move radially along the central axis, thereby realizing adaptive adjustment of the axis centerline position. The sliding plane on the adjustment shaft provides a stable moving track for the sliding sleeve, ensuring that it will not rotate or deviate during radial movement, thereby ensuring the accuracy and stability of the axis centerline adjustment. The oil filling hole, the lubricating oil groove and the oil outlet hole together constitute an efficient lubrication path, ensuring that the lubricating oil is quickly and evenly distributed to each sliding contact surface, reducing the friction coefficient and improving the lubrication efficiency of the system.

[0027] A wire saw machine transmission wheel is also provided. The axis center line of the transmission wheel can be adaptively adjusted by adopting an axle with an adaptively adjustable axis center line as the central rotating shaft, thereby realizing the self-tensioning effect of the wire saw machine transmission wheel. The application of bearings significantly reduces the friction resistance during rotation, improves the energy transfer efficiency, and improves the efficiency of the overall transmission system. The wheel is fixedly nested on the outer ring through the bearing, ensuring its stable position relative to the axle, realizing smooth and efficient rotational movement. The stepped outer ring design of the bearing and the stepped ring of the wheel enhances the connection strength between the wheel and the bearing, ensuring a tight and gapless fit between the two.

A positioning hole 22 is provided on the inner wall of the center hole 21 corresponding to the side where the hydraulic push rod 3 extends, and the sliding sleeve 2 is connected to the driving end 311 of the hydraulic push rod 3 through the positioning hole 22, and can be moved axially along the mounting hole 14 through the hydraulic push rod 3.

[0047] An oil filling hole 15 is provided on the central shaft 1 in the axial direction thereof corresponding to the sliding plane 111, and a lubricating oil groove 17 and an oil outlet hole 16 are provided on the sliding plane 111 corresponding to the sliding sleeve 2.

[0048] The sliding sleeves 2 are mutually abutted and sleeved on the central shaft 1, and an oil outlet groove 23 is provided on the side surface thereof along its radial direction.

[0049] The hydraulic push rod 3 includes a piston rod 31, a guide sleeve 32 and a fixed seat 33. The guide sleeve 32 is arranged on the fixed seat 33. The guide sleeve 32 and the fixed seat 33 are provided with a through hole for the piston rod 31 to pass through along the axial direction of the guide sleeve 32. The piston rod 31 is arranged in the through hole and can move axially along the through hole. The fixed seat 33 is fixed on the sliding plane 111, and the guide sleeve 32 is arranged in the mounting hole 14.

[0050] The working principle and use method of the axle capable of adaptively adjusting the axis centerline of this embodiment: The axle capable of adaptively adjusting the axis centerline provided in this embodiment, the central shaft 1 is the core component of the entire axle system, the central shaft 1 not only provides mechanical support, but also serves as a channel for the transmission of hydraulic fluid, it ensures that all components are properly aligned in space, and provides a mounting base for other components (such as the sliding sleeve 2 and the hydraulic push rod 3); The hydraulic delivery chamber 13 runs through the center shaft 1 and is used to transmit hydraulic oil to the hydraulic push rods 3 in the mounting holes 14. The mounting holes 14 are not only the placement space for the hydraulic push rods 3, but also ensure that the hydraulic oil can be transmitted from the hydraulic delivery chamber 13 to all the hydraulic push rods 3, thereby realizing the synchronous action of each hydraulic push rod 3; after the hydraulic oil enters the hydraulic delivery chamber 13 from the external hydraulic system, it is transmitted to the hydraulic push rod 3 through the mounting holes 14 connected thereto, thereby ensuring that the hydraulic oil can be evenly distributed to each hydraulic push rod 3, so that they can respond to pressure changes synchronously; The fixed shaft 12 is located at both ends of the adjusting shaft 11 and is integrally formed with the adjusting shaft 11. Its main function is to provide structural fixed support. The outer circumference of the fixed shaft 12 is provided with a fixed plane 121 corresponding to the sliding plane 111, so that the two ends of the central shaft 1 can be accurately fixed on the mounting seat to prevent the central shaft 1 from rotating or deviating during use. The outer circumference of the adjusting shaft 11 is symmetrically provided with mutually parallel sliding planes 111 along its axial direction. These planes provide a stable moving track for the sliding sleeve 2. The outer circumference between the sliding planes 111 is provided with a hydraulic plane 112 for arranging the mounting hole 14. The adjusting shaft 11 is responsible for cooperating with the sliding sleeve 2 to adjust the position of the axis centerline to ensure that the sliding sleeve 2 does not rotate or deviate unnecessarily when moving radially. A center hole 21 is provided in the middle of the sliding sleeve 2 corresponding to the cross-sectional shape of the adjusting shaft 11. The inner surfaces of the upper and lower sides of the center hole 21 fit on the sliding plane 111, ensuring that the sliding sleeve 2 can only perform linear motion along a predetermined path (i.e., the sliding plane 111 on the adjusting shaft 11), thereby avoiding unnecessary rotation or tilting. The positioning hole 22 provided on the inner wall of the center hole 21 simplifies the assembly process between the sliding sleeve 2 and the hydraulic push rod 3, thereby reducing possible errors. The oil filling hole 15 provides a channel for conveying the lubricating oil. After the lubricating oil enters through the oil filling hole 15, it is accurately conveyed to the part that needs lubrication through the oil outlet hole 16. The lubricating oil groove 17 is horizontally arranged on the sliding plane 111 along the radial direction of the central axis 1 to ensure that the lubricating oil can cover the entire sliding contact surface. One end of the oil outlet hole 16 is connected to the oil filling hole 15, and the other end is connected to the lubricating oil groove 17 to form a complete lubrication path, which effectively ensures that the lubricating oil can be quickly and evenly distributed to each sliding contact surface, reduces the friction coefficient, and improves the lubrication efficiency of the system; the oil outlet groove 23 arranged along the radial direction on the side surface of the sliding sleeve 2 can make the lubricating oil flowing out of the oil outlet hole 16 cover the contact surface between the sliding sleeves 2 through the oil outlet groove 23, so as to reduce the friction force of the relative movement between adjacent sliding sleeves 2; The hydraulic push rod 3 is composed of a piston rod 31, a guide sleeve 32 and a fixed seat 33. The guide sleeve 32 is arranged on the fixed seat 33, and a through hole is provided inside for the piston rod 31 to pass through. The piston rod 31 can move axially in the through hole. The fixed seat 33 is fixed on the sliding plane 111 to ensure that the hydraulic push rod 3 can be firmly installed on the central axis 1. The guide sleeve 32 not only provides a guiding function, but also plays a sealing role to prevent hydraulic oil leakage and maintain the efficiency of the hydraulic system. When the hydraulic system applies pressure, the piston rod 31 telescopes according to the pressure change of the hydraulic oil, driving the sliding sleeve 2 to move axially along the mounting hole 14.

[0051] When in use, install the hydraulic push rod 3 in the corresponding mounting hole 14, check the sealing between the hydraulic push rod 3 and the mounting hole 14 to ensure that there is no risk of leakage, then sequentially sleeve the sliding sleeve 2 on the adjusting shaft 11, and connect and fix it with the driving end 311 of the hydraulic push rod 3 through the positioning hole 22 on the sliding sleeve 2, then inject a proper amount of lubricating oil through the oil filling hole 15 to ensure that the lubricating oil can smoothly reach the lubricating oil groove 17 and the oil outlet hole 16 to cover each sliding contact surface, check whether the oil outlet groove 23 evenly distributes the lubricating oil to ensure that the contact surface between the sliding sleeves 2 is fully lubricated; and connect the pipeline of the external hydraulic system to the hydraulic delivery chamber 13 of the central shaft 1 , ensure that the connection is well sealed to prevent hydraulic oil leakage, start the hydraulic system, gradually increase the pressure in the hydraulic delivery chamber 13, observe the working status of the hydraulic push rod 3, ensure that they can respond to pressure changes synchronously, and complete the assembly of the wheel axle; after the assembly is completed, use the wheel axle as a whole as a rotating shaft to install the wheel 5, and according to the size of the center hole 21 of the wheel axle, embed a suitable bearing 4 on the corresponding sliding sleeve 2 to install the wheel axle, and then install the fixed shafts 12 at both ends of the central shaft 1 on the corresponding fixed seats 33, and make one side of the hydraulic plane 112 of the central shaft 1 face one end of the principle driving wheel, so as to facilitate the tensioning of transmission components such as the rope saw / transmission chain when the subsequent transmission wheel is used.

[0052] Example 2 like Figure 7-Figure 13As shown, a transmission wheel of a rope saw machine in this embodiment comprises: at least one bearing 4, at least one rotating wheel 5, an end cover 6 and the wheel axle capable of adaptively adjusting the axis center line as described in the first embodiment; The inner ring 41 of the bearing 4 is fixedly nested on the outer circumferential surface of the corresponding sliding sleeve 2, the runner 5 is fixedly nested on the outer ring 42 of the bearing 4, and can rotate synchronously with the outer ring 42, and the end covers 6 are correspondingly arranged at both ends of the central axis 1, and can seal the sides of the bearing 4 and the runner 5 at both ends of the central axis 1.

[0053] The cross-section of the outer ring 42 of the bearing 4 is stepped, and positioning screw holes 421 are evenly distributed on the outer step around the axis. A step ring 51 is provided on the middle part of the rotating wheel 5 corresponding to the outer ring 42 of the bearing 4. A locking screw hole 511 is provided on the step ring 51 corresponding to the positioning screw hole 421. The rotating wheel 5 is fixed to the bearing 4 through the positioning screw hole 421 and the locking screw hole 511. A wheel groove 53 for installing a saw rope is provided on the outer circumferential surface of the rotating wheel 5.

[0054] A sealing groove 52 is provided on the surface of one side of the inner ring of the runner 5 around the axis, and a water seal ring 7 is provided in the sealing groove 52 .

[0055] An adjusting screw hole 61 is provided on the end cover 6 at one end of the wheel axle, and a stopper 18 is correspondingly provided on the central axis 1 at the other end. An adjusting bolt 8 is provided in the adjusting screw hole 61. After the adjusting bolt 8 passes through the adjusting screw hole 61, it abuts against the side of the sliding sleeve 2 through a wear-resistant copper pad 81, and tightens the sliding sleeves 2 at both ends of the wheel axle by cooperating with the stopper 18.

[0056] The working principle and use method of a wire saw transmission wheel of this embodiment: The embodiment provides a driving wheel for a rope saw, wherein the inner ring 41 of the bearing 4 is fixedly nested on the outer circumferential surface of the corresponding sliding sleeve 2 to ensure a tight connection between the two. When the sliding sleeve 2 is driven by the hydraulic push rod 3 to move radially along the central axis 1, the bearing 4 also moves accordingly, thereby adjusting the position of the axis centerline. The rotating wheel 5 is fixedly nested on the outer ring 42 of the bearing 4 to ensure that the rotating wheel 5 can rotate smoothly around the wheel shaft, while ensuring that its position relative to the wheel shaft is stable, thereby avoiding eccentricity or imbalance, and improving the rotation accuracy and system stability. The outer ring 42 of the bearing 4 and the inner ring 41 of the runner 5 are in a step shape that fits with each other. This design increases the contact area between the runner 5 and the bearing 4, improves the strength and stability of the connection, and ensures a tight and gapless fit between the two. In addition, the outer ring 42 of the bearing 4 and the inner ring 41 of the runner 5 are respectively provided with a positioning screw hole 421 and a locking screw hole 511. Through the cooperation of the positioning screw hole 421 and the locking screw hole 511, the runner 5 can be accurately positioned and fixed on the bearing 4, avoiding eccentricity or imbalance caused by assembly errors. A sealing groove 52 is provided on the surface of one side of the inner ring of the runner 5 around the axis, and a water seal ring 7 is provided in the sealing groove 52. The gap between adjacent runners 5 can be sealed by the water seal ring 7. The water seal ring 7 is usually made of a wear-resistant and corrosion-resistant material (such as rubber or Teflon). The main function of the water seal ring 7 is to prevent external moisture, dust and other impurities from entering the transmission system, and also to prevent the internal lubricating medium from leaking, thereby ensuring the cleanliness and reliability of the system. The end covers 6 arranged at both ends of the central axis 1 not only protect the internal components, but also provide structural closure to prevent external impurities from entering the internal mechanical structure, thereby ensuring the cleanliness and reliability of the system. The sliding sleeve 2 can be subjected to appropriate pre-tightening force by adjusting the bolt 8 to prevent unnecessary displacement or vibration during operation, thereby enhancing the stability of the system. The wear-resistant copper pad 81 reduces the wear that may be caused when the adjusting bolt 8 directly contacts the surface of the sliding sleeve 2, thereby extending the service life of the sliding sleeves 2 on both sides.

[0057] When in use, select a bearing 4 of appropriate specifications according to the outer diameter of the sliding sleeve 2 to ensure that the inner ring 41 of the bearing 4 can be tightly nested on the outer circumferential surface of the sliding sleeve 2, and fix and lock the corresponding runner 5 in turn on the corresponding outer ring 42 of the bearing 4, and fix and lock it through the locking screw hole 511 on the runner 5 and the positioning screw hole 421 on the outer ring 42 of the bearing 4. At the same time, during the installation of the runner 5, install the water seal ring 7 in the sealing groove 52 of the corresponding runner 5 to facilitate the sealing of the gap between adjacent runners 5. After the installation of the runner 5 is completed, manually rotate the runner 5 to check whether it is stable and free of jamming to avoid eccentricity or imbalance. Then, install the end covers 6 at both ends of the central shaft 1 to align the bearings 4 and the runner 5 at both ends of the central shaft 1. The surface is sealed to protect the internal components. Finally, the adjusting bolt 8 on the end cover 6 is rotated to apply appropriate pre-tightening force to the sliding sleeve 2 to prevent it from unnecessary displacement or vibration during work. The assembly of the wire rope saw transmission wheel is completed. After the assembly is completed, the transmission wheel is installed at the corresponding position of the wire rope saw, and the pipeline of the external hydraulic system is connected to the hydraulic delivery cavity 13 of the central axis 1, and the pipeline of the lubricating oil system is connected to the oil filling hole 15 to ensure that the connection is well sealed to prevent leakage of hydraulic oil and lubricating oil. The operator can set the required hydraulic pressure through the control system according to the actual working conditions to realize the radial movement of the sliding sleeve 2 along the central axis 1, thereby ensuring that each saw rope can maintain the same tension.
