Description

Technical Field

[0001] This invention relates to two-part bearings in the field of marine engineering, and more particularly to a combined bearing automatic insertion and removal device. Background Technology

[0002] The assembly of large two-part bearings and hubs for through-hull components on ships has been limited by the inherent characteristics of the two-part bearings themselves, the special structure of the hubs, and the space constraints of the construction area. For this project, the assembly has always been carried out manually. The two-part bearings are secured with slings, manually transported to the hub of the through-hull component, then manually lifted and aligned, and finally pulled in using a hand hoist.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] This tooling method is labor-intensive, time-consuming, and inefficient. Furthermore, it poses a significant quality risk due to manual alignment errors that could cause the two halves of the bearing and hub to erode during the insertion process. Summary of the Invention

[0005] To address the shortcomings of existing technologies and the problem of mechanized installation and removal of two-part bearings, this application provides a combined automatic bearing insertion and removal device. This device uses a combined clamping assembly to hold the two-part bearing and allows them to slide axially along a slide bar under the action of a lead screw and nut, thus solving the technical problem of assembling two-part bearings.

The guide block on the screw nut is inserted into the combined clamping assembly. The screw nut and the combined clamping assembly are linked. When the screw rotates, the reaction force of the screw nut pulls the combined clamping assembly, pushing the two halves of the bearing to slide along the slide rod axis.

[0013] The lead screw cap is mounted on one end of the lead screw and connected to the threaded part of the slide rod. It is used to provide axial stopping force and axial adjustment of the lead screw when it is screwed axially.

[0014] The slide bar adjusting cover is assembled on the other end of the lead screw and connected to the threaded part of the slide bar. It is used to provide axial stopping force and axial adjustment of the slide bar when the lead screw is screwed in axial direction.

[0015] The traction sleeve is mounted on the outside of the slide bar adjusting cover and is used to pull the slide bar for hoisting.

[0016] In order to further solve the technical problems to be solved by the embodiments of this application, the combined clamping assembly provided by the embodiments of this application includes a front clamping plate, a rear clamping plate, a connecting rod and a set screw plate;

A guide hole is provided at the front end of the front axle sleeve. A guide block is inserted into the guide hole through the guide groove, so that the screw nut pulls the front pressure plate to drive the front chuck to move. A front retaining ring is provided at the rear end of the front axle sleeve to limit the front linear bearing.

[0020] Furthermore, the front pressure plate includes a web, bushing hole, stop, bolt through hole and internal thread hole;

[0021] The web has a cross structure, with a bushing hole in the center of the web 1 for assembling the front bushing; a stop is provided at the top of the web, with the outer diameter of the stop being larger than the inner diameter of the two bearing halves and smaller than the outer diameter of the end face of the two bearing halves, which serves to stop and propel the two bearing halves when they slide along the sliding rod axis; the web has bolt through holes and internal thread holes, with fixing bolts passing through the bolt through holes to connect the connecting rod, and connecting bolts passing through the bolt holes to connect to the internal thread holes, thus fixing the set screw plate to the front chuck.

[0022] Positive effects: The technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] 1. Because the embodiments of this application adopt the technical means of screwing the nut and the lead screw together and storing them in the slide rod, the combined clamping assembly is assembled on the slide rod, and the guide block is inserted into the combined clamping assembly, which effectively solves the technical problem of assembling two halves of the bearing in the prior art. The nut and the combined clamping assembly can be linked, thereby realizing the technical effect of pushing the two halves of the bearing on the combined clamping assembly to slide along the slide rod axis when the lead screw rotates, and performing the insertion and removal assembly of the two halves of the bearing.

[0024] 2. Because the embodiments of this application use the technical means of sealing the two halves of the bearing with the front and rear clamping plates through the connecting rod, the combined clamping assembly assembled on the slide rod has the function of being detachable and combinable, which effectively solves the technical problem of assembling the two halves of the bearing in the prior art. In this way, the two halves of the bearing can be adjusted in all directions in the sealed state and fully mechanized automatic installation during the installation process, thus achieving the technical effect of effectively replacing the manual installation mode.

[0025] 3. Because the embodiment of this application adopts the technical means of fixing the set screw plate to the front clamping plate on one hand by connecting bolts and abutting against the end faces of the two half bearings on the other hand, it effectively solves the technical problem of assembling the two half bearings in the prior art. Thus, it realizes that the set screw plate can fix the two half bearings by set screws, so that the front clamping plate, the rear clamping plate, the connecting rod and the two half bearings form a stable combination.

[0080] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0081] As shown in the figure, a combined automatic bearing insertion and removal device includes a lead screw 1, a lead screw cover 2, a slide rod 3, a slide rod adjustment cover 4, a lead screw nut 5, a hanger 6, a combined clamping assembly 7, and a traction sleeve 8.

[0082] Lead screw 1 is a threaded shaft that converts torque into axial reciprocating force, providing screwing and pulling forces for screwing in and pulling out the two halves of the bearing;

[0083] The lead screw nut 5 is threadedly connected to the lead screw 1, converting the rotary motion into linear motion. A guide block 51 is mounted on the lead screw nut 5 to limit the trajectory of the lead screw nut 5 to reciprocate along the axis of the lead screw 1.

[0084] The slide bar 3 is a cylindrical structure used to house the lead screw 1 and the lead nut 5. A guide groove 31 is provided on the slide bar 3, and the guide block 51 is assembled in the guide groove 31 for guiding the two half bearings when they are screwed in and pulled out. Threaded parts for connection are provided at both ends of the slide bar 3.

[0085] In this embodiment, the outer diameter coaxiality of the slide rod 3 is φ0.20mm, the cylindricity is 0.20mm, and the parallelism is 0.20mm;

[0086] The lifting bracket 6 is a component assembled on the slide bar 3 and is used to lift and lock the slide bar 3;

[0087] The combined clamping assembly 7 clamps the two halves of the bearing into a stable combined state. It is movably connected to the slide rod 3 and located between the two hangers 6. The guide block 51 on the screw nut 5 is inserted into the combined clamping assembly 7. The screw nut 5 is linked with the combined clamping assembly 7. When the screw 1 rotates, the reaction force of the screw nut 5 pulls the combined clamping assembly 7, thereby pushing the two halves of the bearing to slide along the slide rod 3 axis, realizing the insertion and removal of the two halves of the bearing.

[0088] The lead screw cover 2 is assembled at one end of the lead screw 1 and connected to the threaded part of the slide rod 3. It is used to provide axial stopping force and axial adjustment of the lead screw 1 when it is rotated axially.

[0089] The slide adjustment cover 4 is assembled on the other end of the lead screw 1 and connected to the threaded part of the slide 3. It is used to provide axial stopping force and axial adjustment of the slide 3 when the lead screw 1 is rotated axially.

[0090] The traction sleeve 8 is assembled on the outside of the slide bar adjusting cover 4 and is used to pull the slide bar 3 for hoisting.

[0091] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0092] Since the lead screw 5 is screwed to the lead screw 1 and housed in the slide bar 3, the combined clamping assembly 7 is assembled on the slide bar, and the guide block 51 is inserted into the combined clamping assembly 7, the lead screw 5 and the combined clamping assembly 7 can move together. When the lead screw 11 rotates, the lead screw 5 pushes the two halves of the bearing on the combined clamping assembly 7 to slide along the axial direction of the slide bar 3, so as to perform the insertion and removal assembly of the two halves of the bearing.

[0093] To ensure the stability of the structure in this embodiment, the combined clamping assembly 7 includes a front clamping plate 71, a rear clamping plate 72, a connecting rod 73, and a set screw plate 74.

[0094] A front chuck 71 is provided at the front end of the two bearing halves, and a rear chuck 72 is provided at the rear end of the two bearing halves. The front chuck 71 and the rear chuck 72 are connected by a connecting rod 73 to form an integral structure. The two ends of the connecting rod 73 are locked and fixed by fixing bolts 731. A set screw plate 74 is provided on the front chuck 71 for horizontal adjustment of the end faces of the two bearing halves. The two bearing halves are tightened by diagonal adjustment of the set screws, so that they can be adjusted synchronously with the front chuck 71 and the rear chuck 72 in the up, down and left and right directions. A stop 7113 is provided on the front chuck 71. The outer diameter of the stop 7113 extends into the inner diameter of the two bearing halves, thereby enabling adjustment of the end faces of the two bearing halves.

[0095] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0096] Since the front clamp 71 and the rear clamp 72 seal the two halves of the bearing through the connecting rod 73, and the combined clamping assembly 7 mounted on the slide rod 3 has the function of being detachable and combinable, the two halves of the bearing enable the bearing to be adjusted in all directions under the sealed state and fully mechanized automatic installation during the installation process, thus effectively replacing the manual installation mode.

[0097] To further ensure the stability of the structure in this embodiment, the front clamping plate 71 includes a front pressure plate 711, a front bushing 712, a front linear bearing 713, and a front retaining ring 714.

[0098] A front axle sleeve 712 is provided at the center of the front pressure plate 711. A front linear bearing 713 is embedded in the inner cavity of the front axle sleeve 712 and is mounted on the slide rod 3 for the front clamping plate 71 to slide axially along the slide rod 3. A guide hole 7121 is provided at the front end of the front axle sleeve 712. A guide block 51 is inserted into the guide hole 7121 through the guide groove 31, so that the nut 5 pulls the front pressure plate 711 to drive the front clamping plate 71 to move, thereby realizing the axial sliding of the combined clamping assembly 7 along the slide rod 3. A front retaining ring 714 is provided at the rear end of the front axle sleeve 712 to limit the front linear bearing 713.

[0099] Furthermore, the rear clamping plate 72 includes a rear pressure plate 721, a rear bushing 722, a rear linear bearing 723, and a rear retaining ring 724;

[0100] The rear clamping plate 72 has the same structure as the front pressure plate 711, except that the rear pressure plate 721 does not have a stop 7113 and the rear bushing 722 does not have a guide hole 7121.

[0101] A rear bushing 722 is provided at the center of the rear pressure plate 721. A rear linear bearing 723 is embedded in the inner cavity of the rear bushing 722 and is mounted on the slide rod 3 for the rear chuck 72 to slide axially along the slide rod 3 along the front chuck 71. A rear retaining ring 724 is provided on the rear bushing 722 to limit the rear linear bearing 723.

[0102] Furthermore, the set screw plate 74 is a rectangular plate, and bolt holes 741 and internal threads 742 are provided on the set screw plate 74. The bolt holes 741 are elongated through holes used to adjust the radial position. The connecting bolts 743 pass through the bolt holes 741 to fix the set screw plate 74 on the front chuck 71. The set screws pass through the internal threads 742 and abut against the end faces of the two half bearings for horizontal adjustment.

[0103] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0104] Since the set screw plate 74 is fixed to the front chuck 71 by the connecting bolt 743 on one hand, and abuts against the end faces of the two bearing halves by the set screw on the other hand, the set screw plate 74 can fix the two bearing halves by the set screw, so that the front chuck 71, the rear chuck 72 and the connecting rod 73 and the two bearing halves form a stable assembly. At the same time, the parallelism and perpendicularity of the end faces of the two bearing halves have the function of adjustment and stop fixation.

[0105] To optimize the structure of this embodiment, the front pressure plate 711 includes a web plate 7111, a bushing hole 7112, a stop 7113, a bolt through hole 7114, and an internal thread hole 7115.

[0106] The web plate 7111 has a cross structure. A bushing hole 7112 is provided in the center of the web plate 7111 for assembling the front bushing 712. A stop 7113 is provided at the top of the web plate 7111. The outer diameter of the stop 7113 is larger than the inner diameter of the two half bearings and smaller than the outer diameter of the end face of the two half bearings. When the two half bearings slide along the sliding rod 3, it plays a role in stopping the push. The web plate 7111 has a bolt through hole 7114 and an internal thread hole 7115. The fixing bolt 731 passes through the bolt through hole 7114 to connect the connecting rod 73. The connecting bolt 743 passes through the bolt hole 741 to connect to the internal thread hole 7115, fixing the set screw plate 74 to the front chuck 71.

[0107] In this embodiment, the gap between the outer diameter of the stop 7113 in the front pressure plate 711 and the inner diameter of the two half bearings is 0.05 to 0.15 mm, and the coaxiality of the outer diameter of the stop 7113 is φ0.20 mm and the cylindricity is 0.20 mm.

[0108] To further optimize the structure of this embodiment, the lead screw cover 2 is a nut structure, including a first prism portion 21, a first threaded portion 22, and a rolling bearing I 23;

[0109] A rolling bearing I23 is embedded in the middle of the lead screw cover 2. One end of the lead screw cover 2 is provided with a first threaded part 22 which is connected to the threaded part of the slide rod 3, and the other end is provided with a first prism part 21 for applying torque during connection.

[0110] Furthermore, the slide bar adjusting cover 4 is also a nut structure, including a second threaded part 41, a second prism part 42, a rolling bearing II 43 and a third threaded part 44;

[0111] A rolling bearing II 43 is embedded in the middle of the slide rod adjusting cover 4. One end of the slide rod adjusting cover 4 is provided with a second threaded part 41 that is connected to the threaded part of the slide rod 3, and the other end is provided with a second prism part 42 for applying torque during connection. A third threaded part 44 is provided on the outside of the second prism part 42 for connecting the traction sleeve 8.

[0112] To further optimize the structure of this embodiment, the hanging bracket 6 includes a sliding sleeve 61, a sliding bearing 62, a hanging plate 63, a screw 64, and a retaining ring 65, which have the functions of sliding, rotating, adjusting the center of gravity of the device, and hoisting.

[0113] The sliding sleeve 61 is a bearing sleeve structure. A sliding bearing 62 is embedded in the inner cavity of the sliding sleeve 61 and is limited by a retaining ring 65. A lifting plate 63 is provided on the outer wall of the sliding sleeve 61. The lifting plate 63 has a lifting hole for lifting and transportation. Screws 64 are provided radially on the sliding sleeve 61 to lock the lifting seat 6 and the sliding rod 3 to stop movement.

[0114] As a conventional technical choice, the guide block 51 is a flat key structure connected to the screw nut 5. The screw nut 5 is provided with a keyway for assembling the guide block 51. The guide block 51 extends upward through the guide groove 31 on the slide rod 3 and is inserted into the guide hole 7121 of the front bushing 712, and can slide along the guide groove 31. When the screw 1 rotates, it forms a reaction stop force on the screw nut 5, which drives the front chuck 71, the rear chuck 72, and the connecting rod 73 and the two half bearings to slide along the axis of the slide rod 3 to perform insertion and extraction actions.

[0115] Preferably, the power source for the lead screw 1 end can be provided by a portable handheld electric or pneumatic device.

[0116] The working principle of this embodiment:

[0117] The combined front clamp 71 and rear clamp 72 secure the two bearing halves, allowing for overall adjustment during alignment. The insertion of the traction sleeve 8 and slide rod 3 enables unrestricted alignment in all directions (up, down, left, right, forward, backward), providing both a stable and secure mounting mechanism and sliding operation. Driven by the slide rod 3 and guide block 51, the lead screw 1 provides axial pushing and pulling forces, propelling the two bearing halves in and out along the slide rod 3's direction of travel, thus achieving the installation of the bearing halves. Finally, by combining and separating the components, all parts of the device can be disassembled, completing the sealing, alignment, adjustment, pushing, and pulling of the bearing halves in one seamless, automated process. This achieves a mechanical replacement of manual labor, saving labor costs, reducing labor intensity, improving construction efficiency, and enhancing product quality.

[0118] The working process of this embodiment:

[0119] First, the front clamp 71 and the rear clamp 72 are connected by the connecting rod 73 to form a fixing assembly for clamping the two halves of the bearing. The fixing assembly is inserted into the inner diameter of the two halves of the bearing with the rear clamp 72 (without the stop 7113) as the insertion end until both end faces are in close contact with the two halves of the bearing. Then, the set screw plate 74 is installed, the connecting bolts 743 are tightened, and the set screws are adjusted so that the end faces of the two halves of the bearing are level with the plane of the two halves of the bearing assembly. The set screws are tightened diagonally and the locking nuts are tightened so that the two halves of the bearing and the fixing assembly form a new two-half bearing fixing assembly.

[0120] Next, screw the lead screw 1 into the lead screw nut 5 and insert it into the slide bar 3. First, install and tighten the lead screw cover 2 to make the drive end of the lead screw 1 fit and fix it to the rolling bearing I23. Then, install the slide bar adjustment cover 4 to make the lead screw 1 rotate flexibly in the slide bar 3 without jamming and without axial movement. Then, install and tighten the traction sleeve 8 to complete the slide bar assembly.

[0121] Next, the slide rod assembly is inserted into the front linear bearing 713 and rear linear bearing 723 of the two-half bearing fixing assembly, and adjusted to the maximum stroke required for the installation of the two-half bearings; then the guide block 51 is installed through the guide hole 7121 of the front bushing 712, and is connected and fixed to the keyway on the nut 5 inside the slide rod 3 through the guide groove 31 of the slide rod 3, so that the two-half bearing fixing assembly forms a radial stop when the screw 1 rotates and rotates along the axial direction of the slide rod 3; at the same time, it can achieve the function of changing the running direction of rotation or pull-out when the two-half bearing fixing assembly moves along the axial direction of the slide rod 3.

[0122] Next, install the hanger 6 on the slide bar 3 and adjust it to a suitable position. Then, use the hanger 63 to lift and transport the slide bar assembly with the two half bearing fixing assembly to the shaft hub and fix it through the compartment.

[0123] Next, adjust the slide bar 3 up, down, left and right to meet the installation gap and position requirements, and then use the traction sleeve 8 to pull and fix it in the cabin. Use the drive device to drive the rotating screw 1 so that the two halves of the bearing slide along the axis of the slide bar 3 at a uniform speed until it is installed in place.

[0124] Next, the two halves of the bearing are in close contact with the end face of the shaft hub. Remove the hanger 6, remove the screw cover 2, remove the slide rod 3 and screw 1, and remove the front chuck 71, rear chuck 72, top screw plate 74 and connecting rod 73 to complete the installation of the two halves of the bearing.

[0125] Finally, the process of removing the two bearing halves is reversed. The drive device drives the lead screw 1 to rotate in the opposite direction to remove the two bearing halves from the hub.

[0126] Features of this embodiment:

[0127] This modular automatic bearing insertion and removal device allows for centering and adjustment of the two bearing halves in all directions (up, down, left, right, forward, backward) without spatial limitations, eliminating the influence of space constraints on construction, especially in confined spaces. Furthermore, the device boasts advantages such as simple structure, easy assembly, and ease of operation, making it suitable for the mechanized installation and removal of all bearings consisting of two bearing halves.

[0128] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of lead screw 1, lead nut 5, rolling bearing I 23, rolling bearing II 43, sliding bearing 62, front linear bearing 713, rear linear bearing 723 and set screw are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.
