Description

Technical Field

[0001] This invention belongs to the field of one-way assembly technology, and particularly relates to an assembly support device for a radial floating self-aligning one-way device. Background Technology

[0002] like Figure 1 As shown, the one-way device in this patent application is a radial floating self-aligning one-way device, namely: radial springs 2 are evenly distributed along the circumference of the spline tube. Through the internal elastic support of the drive gear 3 by the radial springs 2, the drive gear 3 can maintain dynamic alignment with the spline tube 1 under normal conditions, and a radial micro-pitch in the range of 0.08~0.15mm is formed between the inner and outer spline meshing surfaces. This radial micro-pitch allows the drive gear to float slightly in the radial direction, thereby compensating for the alignment deviation when meshing with the flywheel. In addition, the one-way device itself has an axial drive gear spring 1.1, realizing dual control of radial floating and axial movement, thereby reducing friction and wear caused by forced spline alignment.

[0003] During the assembly of the spline tube 1 and drive gear 3 in this type of radial floating self-aligning one-way device, the radial spring ejector 2 needs to be pre-compressed before being installed into the spline tube 1, and then the drive gear 3 is assembled. However, manual operation makes it difficult to simultaneously control numerous radial spring ejectors 2 and to accurately control the compression amount of each radial spring ejector 2. Premature release of the radial spring ejector 2 can easily lead to assembly failure (the radial spring ejector 2 extends prematurely to block the drive gear 3), and can also cause the balls 2.4 of the radial spring ejector 2 to collide with the inner wall of the drive gear 3, causing damage. At the same time, the spline tube 1 lacks radial flexible positioning during assembly and is prone to displacement due to vibration, affecting the circumferential uniformity of the radial spring ejector 2 relative to the drive gear 3. Existing equipment cannot simultaneously solve the problems of radial spring ejector release timing control and dynamic positioning. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the prior art, the present invention provides an assembly and bearing device for a radial floating self-aligning one-way device, which solves the problems of uncontrolled preload of radial spring, release timing deviation and dynamic offset of spline tube by means of a linkage dual-path elastic positioning and timing precise release mechanism.

[0005] Technical Solution: To achieve the above objectives, the present invention provides an assembly and support device for a radially floating self-aligning one-way valve, used for assembling a spline tube and a drive gear, wherein radial spring-loaded devices are evenly distributed circumferentially on the spline tube wall, comprising:

[0006] The upper support platform and the lower support platform are fixedly set relative to each other;

[0007] A positioning component, mounted on an upper support platform, includes a positioning groove with a circumferential channel and a positioning rod slidably mounted in the channel. The positioning rod elastically abuts against the outer wall of the spline tube to achieve radial positioning.

[0008] A spring ejector installation mechanism is provided on the lower support platform, including a spring ejector wrench that extends into the spline tube through the bottom opening of the positioning groove, for screwing the radial spring ejector into the spline tube wall;

[0009] The push-release assembly is elastically lifted and mounted on the upper support platform, with its push rod horizontally facing the spline tube. Under normal conditions, the push rod is pressed into the radial spring pusher to retract it inward.

[0010] The linkage mechanism connects the release device and the positioning rod. When the drive gear presses down on the release device, the push rod moves down to release the radial spring and rebounds to support the inner wall of the drive gear. At the same time, the linkage mechanism drives the positioning rod to increase pressure and tighten against the spline tube.

[0011] Furthermore, the inner diameter of the positioning groove is adapted to the outer diameter of the large end of the spline tube, and the large end of the spline tube is positioned downwards in the positioning groove, so that the outer spline of the spline tube faces upwards.

[0012] Furthermore, the spring-loaded device mounting mechanism includes a wrench support arm with a through opening. The lower end of the wrench support arm is sequentially provided with a radial displacement electric guide rail and a directional electric turntable. The upper end of the wrench support arm is provided with a wrench motor for driving the spring-loaded device wrench. The square tenon at the end of the spring-loaded device wrench matches the inner hole of the threaded plug of the radial spring-loaded device. The directional electric turntable is used to drive the wrench support arm to rotate and adjust the direction of the spring-loaded device wrench. The radial displacement electric guide rail is used to drive the wrench support arm to feed the spring-loaded device wrench.

[0013] Furthermore, the release assembly includes a support plate that is elastically lifted and lowered on the upper support platform by means of an elastic part; a limiting ring is fixedly provided on the support plate below the upper support platform, and the limiting ring abuts against the bottom surface of the upper support platform under normal conditions; a push cylinder is provided at the top of the support plate to drive the push rod, and the push cylinder drives the push rod to be horizontally pressed into the radial ejector.

[0014] Furthermore, when the drive gear presses down on the push rod, as the push rod moves down to the axial projection area of ​​the radial spring, the radial spring rebounds and supports the inner wall of the drive gear.

[0015] Furthermore, the elastic linkage mechanism includes a first hinge, a connecting rod, a second hinge, and a rectangular spring connected in sequence; the upper end of the connecting rod is connected to the support plate through the first hinge; the second hinge is elastically connected to the corresponding positioning rod through the rectangular spring; the upper support platform is provided with a guide rail corresponding to the elastic linkage mechanism, and the second hinge and the positioning rod are slidably connected to the guide rail respectively;

[0016] When the push-release component descends, the linkage drives the rectangular spring to compress, increasing the pressure on the positioning rod to tighten.

[0017] Furthermore, the positioning rod abutting end is provided with an inclined surface. When the spline tube sits in the positioning groove, it presses against the inclined surface to make the positioning rod move outward. The rectangular spring stores energy to provide a continuous clamping force.

[0018] Furthermore, the push rod and the positioning rod form a double elastic positioning:

[0019] The push rod indirectly positions the spline tube by pressing the radial spring-loaded device;

[0020] The positioning rod directly and elastically abuts against the outer wall of the spline tube.

[0021] Furthermore, the radial spring is fitted into a radial mounting hole opened in the spline tube wall, and includes a threaded plug, a helical spring, a movable push rod and a ball connected in sequence.

[0022] Furthermore, the inner hole of the threaded plug is an internal hexagonal hole.

[0023] Beneficial effects: This invention uses a push rod to press the radial spring jack horizontally, precisely retracting the balls to a fixed depth within the tube wall, creating an interference-free assembly space and ensuring the helical spring is in a constant preload state. An electric wrench, through an internal hexagonal hole, precisely controls the torque of the threaded plug, ensuring consistent tightening torque of the radial spring jack and preventing over-tightening that could lead to plastic deformation of the spring or insufficient preload. During the downward pressing of the drive gear, the push rod moves strictly vertically downward until it completely disengages from the axial projection area of ​​the radial spring jack, triggering the balls to release and make tangential contact with the inner wall of the drive gear, eliminating the risk of radial collision. The linkage mechanism simultaneously converts the downward pressure of the drive gear into an incremental clamping force of the positioning rod, causing the radial constraint force on the spline tube to adaptively increase with the assembly process, effectively suppressing the micro-vibration and displacement of the tube body at the moment of release of the radial spring jack. The entire process achieves controllable radial spring jack compression, accurate release timing, standardized installation torque, and dynamically controllable positioning clamping force.

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 2 and Figure 3 As shown, an assembly bearing device for a radially floating self-aligning one-way device is used to assemble a spline tube 1 and a drive gear 3. Radial spring-loaded devices 2 are evenly distributed circumferentially on the wall of the spline tube 1. The device includes: an upper bearing platform 5 and a lower bearing platform 10, which are fixedly arranged relative to each other. The upper and lower bearing platforms form a stable reference to ensure no cumulative error during assembly; a positioning component, located on the upper bearing platform 5, including a positioning groove 50 with a circumferential channel 52 and a positioning rod 6 slidingly in the channel 52. The positioning rod 6 elastically abuts against the outer wall of the spline tube 1 to achieve radial positioning, and the positioning rod 6 elastically abuts against the outer wall of the spline tube 1 to automatically center it and absorb radial dimensional fluctuations; and a spring-loaded device installation mechanism 7, located on the lower bearing platform 10, including a spring-loaded device wrench 74 that extends into the spline tube 1 through the bottom opening 51 of the positioning groove 50, used to screw the radial spring-loaded devices 2 into the wall of the spline tube 1. The spring-loaded device wrench 74 installs the radial spring-loaded devices 2 from inside the spline tube 1, avoiding interference from external space. The push-release component 8 is elastically and liftably mounted on the upper support platform 5. Its push rod 84 is horizontally oriented towards the spline tube 1. Under normal conditions, the push rod 84 presses into the radial spring ejector 2 to retract it, thereby creating a non-interference path for the assembly of the drive gear. Moreover, each radial spring ejector 2 can achieve synchronous retraction and synchronous release. The compression amount and release timing are precisely controllable and identical, improving assembly accuracy and yield. The linkage mechanism 9 connects the push-release device 8 and the positioning rod 6. When the drive gear 3 presses down on the push-release device 8, the push rod 84 moves down to release the radial spring ejector 2 and rebounds to support the inner wall of the drive gear 3. At the same time, the linkage mechanism 9 drives the positioning rod 6 to increase pressure and press against the spline tube 1. The linkage mechanism 9 synchronously completes the release of the radial spring ejector 2 and the pressure increase of the positioning rod 6 when the drive gear 3 presses down, avoiding the timing contradiction between the release action and the tube positioning, thereby solving the problems of uncontrolled pre-compression of the radial spring ejector 2, deviation of release timing, and dynamic offset of the spline tube 1.

[0031] like Figure 5As shown, the radial spring ejector 2 is fitted into the radial mounting hole 1a opened in the wall of the spline tube 1. It includes a threaded plug 2.1, a helical spring 2.2, a movable ejector rod 2.3, and a ball bearing 2.4 connected in sequence. The radial spring ejector 2 is evenly distributed along the circumference of the spline tube 1. Through the internal elastic support of the radial spring ejector 2 on the drive gear 3, the drive gear 3 can maintain dynamic alignment with the spline tube 1 under normal conditions, and a radial micro-pitch in the range of 0.08~0.15mm is formed between the inner and outer spline meshing surfaces. This radial micro-pitch allows the drive gear 3 to float slightly in the radial direction, thereby compensating for the alignment deviation when meshing with the flywheel. In addition, the axial drive gear spring 1.1 of the one-way device itself realizes dual control of radial floating and axial movement, thereby reducing friction and wear caused by forced spline alignment.

[0032] The inner diameter of the positioning groove 50 is adapted to the outer diameter of the large end of the spline tube 1. The large end of the spline tube 1 is positioned downward in the positioning groove 50. The large end of the spline tube 1 is positioned downward to resist vibration and offset by its structural rigidity. This allows the outer spline of the spline tube 1 to face upward, so that the drive gear 3 is assembled along the direction of gravity. When the radial spring 2 is released, the inner wall of the drive gear 3 makes natural tangential contact with the ball 2.4, eliminating the risk of collision.

[0033] like Figure 3 As shown, the spring-loaded device mounting mechanism 7 includes a wrench support arm 71 that passes through the opening 51. The lower end of the wrench support arm 71 is sequentially provided with a radial displacement electric guide rail 72 and a directional electric turntable 73. The upper end of the wrench support arm 71 is provided with a wrench motor 75 that drives the spring-loaded device wrench 74. The square tenon at the end of the spring-loaded device wrench 74 matches the inner hole of the threaded plug 2.1 of the radial spring-loaded device 2. The directional electric turntable 73 is used to drive the wrench support arm 71 to rotate and adjust the direction of the spring-loaded device wrench 74. The radial displacement electric guide rail 72 is used to drive the wrench support arm 71 to feed the spring-loaded device wrench 74. The radial displacement electric guide rail 72 enables precise axial feeding of the spring-loaded device wrench 74, while the directional electric turntable 73 controls the circumferential angle to ensure accurate installation of the radial spring-loaded device 2. The inner hole of the threaded plug 2.1 is an internal hexagonal hole, and the square tenon cooperates with the internal hexagonal hole to transmit torque and avoid slippage; at the same time, the electric drive ensures constant speed and force during the installation process.

[0034] like Figure 3 and Figure 4As shown, the release assembly 8 includes a support plate 80 that is elastically and vertically mounted on the upper support platform 5 and supported by an elastic part 81; a limiting ring 82 is fixedly mounted on the support plate 80 below the upper support platform 5, and the limiting ring 82 abuts against the bottom surface of the upper support platform 5 under normal conditions; a push cylinder 83 is provided at the top of the support plate 80 to drive a push rod 84, and the push cylinder 83 drives the push rod 84 to be horizontally pressed into the radial ejector 2. The limiting ring 82 locks the initial height of the push rod 84, ensuring that its axis is strictly aligned with the radial ejector 2. The push cylinder 84 applies horizontal pressure to avoid oblique force, ensuring that the movable push rod 2.3 of the radial ejector 2 retracts in a straight line without jamming.

[0035] When the drive gear 3 presses down on the push rod 84, as the push rod 84 moves down to the point where it is out of the axial projection area of ​​the radial spring ejector 2, the radial spring ejector 2 rebounds and supports the inner wall of the drive gear 3. After the push rod 84 moves down to the point where it is completely out of the axial projection area of ​​the radial spring ejector 2, it is released, so that when the balls 2.4 of the radial spring ejector 2 are ejected, they make tangential contact with the inner wall of the drive gear 3, eliminating radial impact, and the release timing is precisely matched with the downward movement of the drive gear 3.

[0036] like Figure 3 and Figure 4 As shown, the elastic linkage mechanism 9 includes a first hinge 91, a connecting rod 92, a second hinge 93, and a rectangular spring 94 connected in sequence. The upper end of the connecting rod 92 is connected to the support plate 80 through the first hinge 91. The second hinge 93 is elastically connected to the corresponding positioning rod 6 through the rectangular spring 94. The upper support platform 5 is provided with a guide rail 95 corresponding to the elastic linkage mechanism 9, and the second hinge 93 and the positioning rod 6 are slidably connected to the guide rail 95. When the push-release assembly 8 descends, the connecting rod 92 drives the rectangular spring 94 to compress, increasing the pressure on the positioning rod 6. The connecting rod 92 converts the downward movement of the push rod 84 into the compression of the rectangular spring 94, pushing the positioning rod 6 to increase pressure and tighten, while the guide rail 95 constrains the movement trajectory, ensuring the stability of the force transmission direction.

[0037] The positioning rod 6 has an inclined surface 60 at its abutting end. When the spline tube 1 sits in the positioning groove 50, it presses the inclined surface 60 to move the positioning rod 6 outward. The rectangular spring 94 stores energy to provide a continuous clamping force. At this time, the clamping force is adaptive and compatible with the outer diameter tolerance of the tube.

[0038] More specifically, the push rod 84 and the positioning rod 6 form a dual elastic positioning system: the push rod 84 indirectly positions the spline tube 1 by pressing the radial spring jack 2; the positioning rod 6 directly and elastically abuts against the outer wall of the spline tube 1. In this system, the push rod 84 pressing the radial spring jack 2 forms an indirect rigid constraint, while the positioning rod 6 directly and elastically abuts against the tube wall, thus suppressing assembly vibration displacement through dual-path positioning.

[0039] This invention utilizes a push rod 84 to press horizontally into the radial spring ejector 2, precisely retracting the ball 2.4 to its fixed depth within the tube wall, creating an interference-free assembly space and ensuring the helical spring 2.2 is in a constant preload state. An electric wrench, through its internal hexagonal hole, precisely controls the torque of the threaded plug 2.1, ensuring consistent tightening torque of the radial spring ejector 2 and preventing over-tightening that could lead to plastic deformation of the spring or insufficient preload. During the downward pressing of the drive gear 3, the push rod 84 moves strictly vertically downward until it completely disengages from the axial projection area of ​​the radial spring ejector 2, triggering the ball 2.4 to release and tangentially contact the inner wall of the drive gear 3, eliminating the risk of radial collision. The linkage mechanism 9 simultaneously converts the downward pressure of the drive gear 3 into an incremental clamping force of the positioning rod 6, causing the radial constraint force on the spline tube 1 to adaptively increase with the assembly process, effectively suppressing the tube's micro-vibration and displacement at the moment of release of the radial spring ejector 2. The entire process achieves controllable radial spring ejector compression, accurate release timing, standardized installation torque, and dynamically controllable positioning clamping force.

[0040] It should be noted that the assembly sequence is as follows: pre-install radial spring ejector 2 into the radial mounting hole 1a of spline tube 1, position spline tube 1, tighten radial spring ejector 2, sleeve axial drive gear spring 1.1 on spline tube 1, assemble drive gear 3, assemble retaining ring 1.2, and assemble limit ring 1.3.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
