Description

Technical Field

[0001] This invention relates to the field of gear shaft mounting technology, and more specifically, to a gear shaft mounting structure for gear transmission. Background Technology

[0002] Currently, during the maintenance and replacement of gear transmission devices, when a new gear or gear shaft needs to be replaced, it is necessary to install the new gear or gear shaft. However, when installing a gear and gear shaft in an interference fit configuration, it is difficult to directly insert the gear shaft into the gear shaft hole, especially when the gear shaft is long. The auxiliary clamping and positioning accuracy of the gear and gear shaft is poor, and it is difficult to ensure that the center of the gear shaft and the center of the gear hole are in a constant state during each hammering process. This can lead to damage to the inner wall of the gear shaft and the gear shaft hole, resulting in slight extrusion deformation and inaccurate fit.

[0003] Therefore, those skilled in the art have provided a gear shaft mounting structure for gear transmission to solve the problems mentioned in the background art. Summary of the Invention

[0011] Horizontal guide rails fixed to the walls of the square box frame;

[0012] The drive seat mounted on the horizontal guide rail has a set of telescopic rods hinged to its upper, middle and lower end faces. The output end of the telescopic rod in the middle is hinged to the middle of the expansion sleeve rod. The output end of the telescopic rod in the upper part is hinged to the upper end of the expansion sleeve rod at the bottom right and left ends of the trapezoidal clamping block, respectively. The output end of the telescopic rod in the lower part is hinged to the lower end of the expansion sleeve rod at the lower and upper ends of the outer side of the positioning component, respectively.

[0014] The concave plate frame used for load support has three sets of columnar bars arranged axially and horizontally on its inner side wall. Each set of columnar bars is fitted with multiple sets of axially arranged and radially pointing elastic telescopic rods. The inner end of each elastic telescopic rod on each set of columnar bars is fixed to the outer side wall of a set of axial square bars. Each set of square bars has axially arranged sensing clamping rollers installed on its inner side wall via slidable and detachable I-shaped plates.

[0015] Multiple sets of pressure-diffusing springs are configured for connection between adjacent square bars;

[0016] Telescopic rod two is used to connect the end of the square bar on the outside with the end of the concave plate frame on the corresponding side.

[0017] As a preferred embodiment of the present invention, the elastic telescopic member includes:

[0018] A concave plate sleeve that is fixed to the cylindrical bar;

[0019] The free telescopic rod installed on the concave plate sleeve has its inner end fixed to the outer wall of the square bar, and its outer end is fitted with a clamping spring for connecting the outer wall of the square bar and the concave plate sleeve respectively.

[0020] As a preferred embodiment of the present invention, an angle monitoring disk is fixed on the concave plate frame, which is rotatably connected to the end of a cylindrical bar at the center of the axis, and a rotation pointer is coaxially fixed on the surface of the angle monitoring disk at the upper end of the cylindrical bar.

[0029] In this invention, the gear shaft and gear are electromagnetically heated, causing a slight increase in the diameter of the gear's inner hole. This slightly reduces the hardness and wear resistance of the original crystalline structure on the outer surface of the gear shaft, facilitating the fitting and installation of the gear shaft and gear. The shaft positioning device provides a guiding and retaining function for the gear shaft and gear, ensuring smooth movement of the gear shaft as it is hammered into the gear hole. Combined with the damping effect of the positioning rod, the gear shaft moves forward and backward in tandem, reducing the tendency of the gear shaft to deviate from the axis after each hammering. This improves the accuracy and quality of the fitting and installation of the gear shaft and gear. Attached Figure Description

[0035] Reference Figure 1-4 The present invention provides a technical solution: a gear shaft mounting structure for gear transmission, comprising:

[0036] A square box frame 1 with a shock-absorbing seat installed at the bottom, and two sets of coils 2 arranged in upper and lower layers are installed inside. The coils 2 are independently controlled by a control box 4. A hammer pressing device 6 is also provided above the square box frame 1.

[0037] A axial positioning device 5 is symmetrically arranged above and below the lower coil and distributed in a circle, and is installed on the wall of the square box frame 1. It is used for positioning the gear and positioning and guiding the movement of the gear shaft.

[0038] Guide clamps 3, which are circumferentially distributed and mounted on the upper end of the square frame 1 for axial transport and guidance of the gear shaft; and

[0039] The positioning rod 7 is set at the shaft part of the lower shaft positioning device 5 and is used for fixing the gear, as well as cooperating with the shaft positioning and movement guidance of the gear shaft embedded in the gear;

[0040] In this configuration, the upper and lower axial positioning devices face the end for positioning and fixing the gear. The shaft of the upper axial positioning device is used for positioning and guiding the gear shaft, while the shaft of the lower axial positioning device is used for clamping the positioning rod. The positioning rod has an adjustable inner diameter and is used to embed into the inside of the gear hole to assist in the positioning and clamping of the gear shaft. During the process of the gear shaft entering the gear hole, it provides a small amount of resistance to the axial displacement movement of the gear shaft in a forward and backward motion. This improves the accuracy of the gear shaft's axial embedding along the gear hole wall, thereby avoiding the situation where the lower end face of the gear shaft is an empty area after each hammering of the gear shaft by the hammering device. Without a support surface to cooperate with the axial displacement movement of the gear shaft, the direction of each small displacement movement of the gear shaft is prone to deviate from the axis, resulting in line and surface scraping between the lower end ring edge of the gear shaft and the gear hole wall, which in turn causes scratches and damage to the smooth wall of the gear hole.

[0041] In this embodiment, the guide clamp 3 includes a radially extending push rod 31 and a guide double pressure roller 32 installed at the output end of the push rod 31. The guide roller in the guide double pressure roller 32 is installed by rotating a damping roller. Through the action of the small damping force of the damping roller, the gear shaft is hammered by the hammering device each time, avoiding the tendency of the gear shaft to retract due to the rigidity of the rigid structural surface. This improves the effective engagement displacement of the gear shaft after each hammering, thereby improving the engagement installation efficiency.

[0042] In this embodiment, the shaft positioning device 5 includes:

[0043] Horizontal guide rail 51 is fixed to the wall of the square box frame 1;

[0044] The drive seat 52, mounted on the horizontal guide rail 51, has a set of telescopic rods 53 hinged to its upper, middle, and lower ends. The output end of the middle telescopic rod 53 is hinged to the middle of the expansion sleeve 56. The output end of the upper telescopic rod 53 is hinged to the upper end of the expansion sleeve 56 at the bottom right and left ends of the trapezoidal clamping block 54, respectively. The output end of the lower telescopic rod 53 is hinged to the lower end of the expansion sleeve 56 at the lower and upper ends of the outer side of the positioning assembly, respectively. The trapezoidal clamping block 54 is provided with an X-shaped air-shrinkable mesh pad 541 to improve the friction and adsorption strength with the gear shaft, and to absorb the high-frequency micro-vibrations generated on the surface of the gear and gear shaft due to the rigid material after each impact. This avoids gear displacement after each hammering, facilitates increasing the hammering frequency, and thus improves the hammering efficiency.

[0045] In this embodiment, the positioning component 55 includes:

[0046] The concave plate frame 551 used for load support has three sets of columnar bars 552 arranged axially and horizontally on its inner side wall. Each set of columnar bars 552 is fitted with multiple sets of axially arranged and radially pointing elastic telescopic rods 554. The inner end of each elastic telescopic rod 554 located on a set of columnar bars 552 is fixed to the outer side wall of a set of axial square bars 553. Each set of square bars 553 has axially arranged sensing clamping rollers 555 installed on the inner side wall of the set of square bars 553 through a slidable and detachable I-shaped plate 556.

[0047] The pressure-diffusing springs 5510 are configured in multiple groups for connection between adjacent square bars 553;

[0048] Telescopic rod 557 is used for connecting the end of the square bar on the outer side with the end of the concave plate frame 551 on the corresponding side;

[0049] In this structure, the flexible telescopic rods are arranged to connect the gear shafts. If the radius of the gear shaft is r, the radius of the aperture formed by the sensing clamping wheel can be greater than or less than r, thereby improving the compatibility with different gear shafts. Furthermore, by adjusting the telescopic rod, firstly, it is convenient to change the direction of the force applied to the gear shaft surface, and secondly, it is convenient to adjust the area of ​​the force applied to the gear shaft surface, thereby making the clamping and fixing of the gear shaft more stable.

[0050] Furthermore, the elastic telescopic member 554 includes:

[0051] A concave plate sleeve 5541 is fixedly connected to the columnar bar 552;

[0052] The free telescopic rod 5541 installed on the concave plate sleeve 5541 has its inner end fixed to the outer wall of the square bar 553, and its outer end is fitted with a clamping spring 5543 with its two ends respectively used to connect the outer wall of the square bar 553 and the concave plate sleeve 5541.

[0053] Furthermore, an angle monitoring disk 558 is fixed on the concave plate frame 551, which is rotatably connected to the end of the columnar bar 552 through the axis. A rotation pointer 559 located on the surface of the angle monitoring disk 558 is coaxially fixed at the upper end of the columnar bar 552.

[0054] In this embodiment, a pressure sensing module is also included for feedback monitoring and control of the pressure between the pressure roller 555 and the outer wall of the gear shaft, so as to control the intensity of the applied force on the gear shaft.

[0055] In this embodiment, the positioning rod 7 includes:

[0056] The guide base 71 has guide grooves 72 distributed circumferentially on its upper surface. A rotary motor 75 is fixed to the shaft of the upper surface. A double threaded screw 76 is fixed to the output end of the rotary motor 75. The double threaded screw 76 is rotatably connected to the bottom end of the shaft of the guide top plate 73. A second guide groove 74 is distributed circumferentially in the guide top plate 73.

[0057] The upper and lower ends of the L-shaped auxiliary support rod 78 are slidably connected to the guide slide groove 2 74 and the guide slide groove 1 72 respectively, and the axial rod in the L-shaped auxiliary support rod 78 is a fan-shaped rod structure.

[0058] Two sets of cross-shaped threaded sleeves 77 are respectively fitted onto the upper and lower threaded surfaces of the double-threaded screw 76, and the cross-shaped threaded sleeve 77 on each side is connected to the inner wall of the L-shaped auxiliary support rod 78 on the corresponding side through the inner support rod 79.

[0059] In this process, the planar damping effect of the guide plate ensures that the guide plate is in close contact with the lower end face of the gear shaft in real time, thereby preventing the gear shaft from deviating from the axis.

[0060] Furthermore, a pressure pad is installed on the upper surface of the guide plate 73.

[0061] Furthermore, a temperature monitoring element is installed inside the pressure plate to adjust the accuracy of the electromagnetic heating temperature.

[0062] In its specific implementation, it includes the following steps:

[0063] S1: Adjust the diameter of the positioning rod according to the size of the gear hole, and insert the upper end of the positioning rod into the upper end of the gear hole and make it flush with the upper end surface;

[0064] S2: Install the gear and positioning rod in the shaft positioning device, embed the gear shaft into the guide clamp shaft, start the control box to electromagnetically heat the gear shaft and gear, and at the same time further embed the gear shaft into the shaft positioning device, and adjust the lower end face of the gear shaft to fit against the upper end face of the positioning rod;

[0065] S3: Start the hammer pressing device to perform hammer pressing until the gear shaft and gear are properly engaged and installed.

[0066] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
