Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and in particular to a drum gear coupling installation auxiliary device and a use method thereof. Background Art

[0002] In actual work scenarios using drum gear couplings, it is often necessary to disengage the inner and outer gear sleeves to perform related work, and then re-engage the inner and outer gear sleeves after the work is completed. However, when reassembling the disassembled gear coupling at the work site, most people use manual assistance to lift and straighten the outer gear sleeve to re-engage the inner and outer gear sleeves. However, this method has many problems, and even skilled personnel find it difficult to complete the work accurately and quickly. Especially when dealing with large couplings, their heavy weight significantly increases the difficulty of operation, which is not only laborious but also time-consuming.

[0003] To improve meshing speed and accuracy, existing methods typically use multiple clamping blocks to clamp onto the internal tooth grooves of the gear sleeve of a gear coupling. However, this method has significant limitations. It can only clamp and secure a specific model of gear sleeve. Moreover, when the gear sleeve is subjected to large external forces, the clamping blocks can easily damage the internal tooth grooves, seriously affecting the quality of the gear sleeve. Therefore, there is an urgent need for an effective drum gear coupling installation auxiliary device and method to address the difficulties of existing technologies in reassembling and positioning gear couplings. Summary of the Invention

The structure is simple, the use is convenient, and the work efficiency and work precision are effectively improved.

[0031] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment provides an installation assistor for a drum gear coupling, including: a base frame 1, a base 20, a first support member, a first sliding seat 30, a hanging member, a second sliding seat 40, a second support member, and a first driving member. The length direction of the base 20 is the first direction, and the vertical direction perpendicular to the base frame 1 is the second direction; the base 20 is disposed at the first end of the base frame 1. The top end of the first support member is slidably connected to the base 20 in the second direction and can maintain the position after sliding. The bottom end of the first support member is used to abut against the outer sidewall of one end of the inner gear ring 6 passing through the outer gear ring 7 so that the inner gear ring 6 can support the base 20; the first sliding seat 30 is slidably connected to the base frame 1 in the first direction and can maintain the position after sliding; the top end of the hanging member is slidably connected to the first sliding seat 30 in the second direction and can maintain the position after sliding. The bottom end of the hanging member is used to be detachably fixedly connected to the outer gear ring 7 to drive the outer gear ring 7 to move to a position where its axis coincides with the axis of the inner gear ring 6; the first sliding seat 30 is slidably connected to the base frame 1 in the first direction and can maintain the position after sliding; the top end of the second support member is slidably connected to the first sliding seat 30 in the second direction and can maintain the position after sliding. The bottom end of the second support member is used to abut against the outer sidewall of the inner gear ring 6 so that the inner gear ring 6 can support the first sliding seat 30; the first driving member is used to drive the second sliding seat 40 to move towards the first sliding seat 30 so that the bottom end of the second support member presses the outer gear of the inner gear ring 6 and drives the inner gear ring 6 to move. When the outer gear of the inner gear ring 6 and the inner gear of the outer gear ring 7 are at an angle where they can mesh, the inner gear ring 6 is pressed into the outer gear ring 7 and forms a meshing state. Through the sliding connections in different directions and the mutual support effects between the components, the relative positions and angles of the inner gear ring 6 and the outer gear ring 7 can be flexibly adjusted, providing a variety of adjustable methods for the accurate installation of the drum gear coupling. It can better meet the installation requirements of drum gear couplings of different specifications, improving the installation accuracy and versatility. For example, during the actual installation process, the axial alignment of the inner and outer gear rings and the meshing angle between teeth can be accurately adjusted, reducing the installation error and enhancing the stability and transmission efficiency of the coupling during operation.

[0034] In a preferred solution of this embodiment, the first driving member includes a transverse lead screw 50. The base frame 1 is a rectangular bracket. A long strip-shaped slideway 11 is provided at the top of the base frame 1. A first transverse threaded hole is provided at one end of the base frame 1 away from the base 20. The transverse lead screw 50 is threadedly connected to the first transverse threaded hole, and one end of the transverse lead screw extending into the long strip-shaped slideway 11 is rotatably connected to the second sliding seat 40. A first adjusting hole 51 perpendicular to the transverse lead screw 50 is provided at one end of the transverse lead screw 50 extending out of the long strip-shaped slideway 11. The design that the transverse lead screw 50 is threadedly connected to the base frame 1 and rotatably connected to the second sliding seat 40 enables the precise control of the movement of the second sliding seat 40 on the long strip-shaped slideway 11 of the base frame 1 by rotating the transverse lead screw 50. The setting of the first adjusting hole 51 facilitates the operator to use tools to rotate and adjust the transverse lead screw 50. This structure can achieve precise and stable driving, which helps to precisely control the moving distance and speed of the second sliding seat 40, and further precisely control the extrusion action of the internal gear ring 6 and the external gear ring 7, improving the accuracy and stability of the installation of the drum-shaped tooth coupling, and making the installation process more reliable and efficient.

[0035] In a preferred solution of this embodiment, the first driving member further includes a spring 52, a connecting column 53 and a limiting plate 54. A lead screw adjusting seat 41 is provided on the second sliding seat. The lead screw adjusting seat 41 is slidably connected in the long strip-shaped slideway 11. The lead screw adjusting seat 41 is provided with a transverse through hole. One end of the connecting column 53 passes through the transverse through hole. The limiting plate 54 is vertically and fixedly connected to one end of the connecting column 53 passing through the transverse through hole to prevent the connecting column 53 from disengaging from the transverse through hole. One end of the connecting column 53 is fixedly connected to the transverse lead screw 50. The spring 52 is sleeved outside the connecting column 53, and one end of the spring 52 abuts against the transverse lead screw 50, and the other end is used to abut against the lead screw adjusting seat. The addition of the spring 52, the connecting column 53 and the limiting plate 54 makes the driving structure have a certain elastic buffering effect. When the transverse lead screw 50 is rotated to drive the second sliding seat to move, the spring 52 can buffer the possible impact force, avoid damage to the equipment caused by rigid collision, and at the same time helps to push the second sliding seat to move more smoothly. The limiting plate 54 ensures the connection stability between the connecting column 53 and the lead screw adjusting seat 41, preventing the connecting column 53 from disengaging and affecting the normal operation of the equipment. Overall, it enhances the stability and reliability of the driving structure, extends the service life of the equipment, and can better cope with the possible tiny impacts and vibrations during the installation of the coupling, ensuring the installation quality.

[0036] In a preferred solution of this embodiment, the hanging member includes a first telescopic sleeve 31, a first adjusting lead screw 32, and a stepped column 33. A first sleeve 35 is fixedly connected to the bottom of the first sliding seat 30. The first sliding seat 30 is provided with a first through hole. The first telescopic sleeve 31 is sleeved inside the first sleeve 35, and a first threaded hole is provided at the top of the first telescopic sleeve 31. The bottom end of the first adjusting lead screw 32 passes through the first through hole and is threadedly connected to the first threaded hole. Rotating the first adjusting lead screw 32 can drive the first telescopic sleeve 31 to slide in the second direction. First elongated through slots are provided on both side walls of the first sleeve 35 in the first direction. A first mounting hole is provided at the bottom of the first telescopic sleeve 31. The end of the stepped column 33 with a smaller cross-sectional area is used to be inserted into the first mounting hole, and the end of the stepped column 33 with a larger cross-sectional area is used to be inserted into the flange hole of the external gear ring 7. By driving the first telescopic sleeve 31 to slide in the second direction with the first adjusting lead screw 32, the height position of the stepped column 33 can be flexibly adjusted to meet the installation requirements of external gear rings 7 of different models. The elongated through slots enable the stepped column 33 to pass through. The plug-in connection method of the stepped column 33 with the first telescopic sleeve 31 and the external gear ring 7 realizes the detachable connection between the hanging member and the external gear ring 7 conveniently and quickly, can quickly position and adjust the position of the external gear ring 7 during the installation process, improves the installation efficiency, and also helps to ensure the position accuracy and installation quality between the external gear ring 7 and the internal gear ring 6.

[0037] In a preferred solution of this embodiment, a side lead screw 34 is further included. A second horizontal threaded hole is provided on one side of the base 20. A rotating connection portion is provided on one side of the first sliding seat 30. The side lead screw 34 is used to be threadedly connected to the second horizontal threaded hole, and the end of the side lead screw 34 passing through the second horizontal threaded hole is used to be rotatably connected to the rotating connection portion. A second adjusting hole 36 perpendicular to the side lead screw 34 is provided at the end of the side lead screw 34 away from the first sliding seat. The setting of the side lead screw 34 can further finely adjust the relative positional relationship between the base 20 and the first sliding seat 30 through its connection with the base 20 and the first sliding seat 30. When fine adjustment of the overall structure of the auxiliary device for the drum tooth coupling is required, the first sliding seat 30 can be made to move slightly relative to the base 20 in the first direction by rotating the side lead screw 34, so as to optimize the installation position and angle of the internal gear ring 6 and the external gear ring 7 at a finer level, further improve the installation accuracy, and meet the high-precision requirements of different installation scenarios.

[0038] In a preferred solution of this embodiment, the second support member includes a second telescopic sleeve 42, a second adjusting lead screw 43, and two first rollers 44. The bottom of the second sliding seat 40 is fixedly connected to a second sleeve 45, and a second through hole is provided at the top of the second sliding seat 40. The second telescopic sleeve 42 is sleeved in the second sleeve 45, and a second threaded hole is provided at the top of the second telescopic sleeve 42. The bottom end of the second adjusting lead screw 43 passes through the second through hole and is threadedly connected to the second threaded hole. Rotating the second adjusting lead screw 43 can drive the second telescopic sleeve 42 to slide in the second direction. The two first rollers 44 are installed on both sides of the bottom end of the second telescopic sleeve 42 to rollingly abut against the outer side wall of the internal gear ring 6. By rotating the second adjusting lead screw 43 to drive the second telescopic sleeve 42 to slide in the second direction, the height of the second support member can be adjusted according to the actual size and installation requirements of the internal gear ring 6 to better support and squeeze the internal gear ring 6. The first rollers 44 rollingly abut against the outer side wall of the internal gear ring 6, changing the sliding friction into rolling friction, reducing the frictional force, avoiding damage to the outer side wall of the internal gear ring 6, and at the same time enabling the internal gear ring 6 to enter the external gear ring 7 more smoothly during the extrusion process, ensuring the meshing effect, and improving the service life and installation quality of the equipment.

[0039] In a preferred solution of this embodiment, the first support member includes a third telescopic sleeve 21, a third adjusting lead screw 22, and two second rollers 23. The bottom of the base 20 is fixedly connected to a third sleeve 24, and a third through hole is provided at the top of the base 20. The third telescopic sleeve 21 is sleeved in the third sleeve 24, and a third threaded hole is provided at the top of the third telescopic sleeve 21. The bottom end of the third adjusting lead screw 22 passes through the third through hole and is threadedly connected to the third threaded hole. Rotating the third adjusting lead screw 22 can drive the third telescopic sleeve 21 to slide in the second direction. The two second rollers 23 are installed on both sides of the bottom end of the third telescopic sleeve 21 to rollingly abut against the outer side wall of the internal gear ring 6. Similar to the second support member, this structure helps to flexibly adjust the height of the first support member to better meet the support requirements of different internal gear rings 6. The way that the rollers rollingly abut against the outer side wall of the internal gear ring 6 reduces the frictional force during the support process, improves the stability of the support, and is beneficial to protecting the outer side wall structure of the internal gear ring 6, ensuring that the internal gear ring 6 will not be damaged due to excessive friction during the support process, and providing a stable and reliable support basis for the accurate installation of the drum gear coupling.

A fourth through hole is provided at the top of the base 20, and a fifth through hole is provided at the top of the third telescopic sleeve 21. The slider 26 is provided with a fourth threaded hole. The slider 26 is sleeved in the three telescopic sleeves and is slidably connected to the third telescopic sleeve 21. The fourth adjusting lead screw 25 passes through the fourth through hole and the fifth through hole and is threadedly connected to the fourth threaded hole. Second long strip-shaped through grooves are provided on both side walls of the third sleeve 24 in the first direction, and third long strip-shaped through grooves are provided on both side walls of the third telescopic sleeve 21 in the first direction. A second mounting hole is provided at the bottom of the slider 26. The bolt 27 is used to pass through the second mounting hole and connect to the mounting hole on one side of the outer tooth ring sleeve 7. The structure composed of the fourth adjusting lead screw 25, the slider 26 and the bolt 27 provides an additional position adjustment and fixing method. By rotating the fourth adjusting lead screw 25, the position of the slider 26 in the third telescopic sleeve 21 can be finely adjusted, and then the position of one side of the outer tooth ring sleeve 7 can be changed, so as to better achieve the position alignment of the inner tooth ring sleeve 6 and the outer tooth ring sleeve 7. The long strip-shaped through grooves provide guidance and limit for the sliding of the slider 26 and the third telescopic sleeve 21, ensuring the accuracy of the adjustment. The connection method of the bolt 27 ensures the stable connection of the outer tooth ring sleeve 7 with the slider 26 and the entire auxiliary structure, further improving the accuracy and stability of the installation of the drum tooth coupling. The structure composed of the fourth adjusting lead screw 25, the slider 26 and the bolt 27 provides an additional position adjustment and fixing method. By rotating the fourth adjusting lead screw 25, the position of the slider 26 in the third telescopic sleeve 21 can be finely adjusted, and then the position of one side of the outer tooth ring sleeve 7 can be changed, so as to better achieve the position alignment of the inner tooth ring sleeve 6 and the outer tooth ring sleeve 7. The long strip-shaped through grooves provide space for the passing of the screw, and the connection method of the bolt 27 ensures the stable connection of the outer tooth ring sleeve 7 with the slider 26 and the entire auxiliary structure, further improving the accuracy and stability of the installation of the drum tooth coupling.

[0041] Embodiment Two

[0042] This embodiment also provides a method for using the installation auxiliary of the drum tooth coupling in Embodiment One, including the following steps:

[0043] Preparation stage: Assemble the various parts of the installation auxiliary.

[0044] Initial adjustment steps:

[0045] First step: Rotate the second adjusting lead screw 43. Since the second adjusting lead screw 43 cooperates with the second threaded hole, the second telescopic sleeve 42 and the first roller 44 thereon move upward until the limit position is reached.

[0046] Step 2: Rotate the first adjusting lead screw 32. Based on the cooperation between the first adjusting lead screw 32 and the first threaded hole, move the first telescopic sleeve 31 and the stepped column 33 installed in the first mounting hole downward synchronously to the limit position.

[0047] Step 3: Rotate the third adjusting lead screw 22. By virtue of the cooperation between the third adjusting lead screw 22 and the third threaded hole, promote the third telescopic sleeve 21 and the second roller 23 thereon to move upward together to the limit position. When this step is completed, install the bolt 27 in the second mounting hole.

[0048] Installation and positioning steps:

[0049] Positioning operation: Pass the stepped column 33 through the flange hole of the external gear ring sleeve 7. Drive the base frame 1 to slide and then drive the base 20 to move by rotating the side lead screw 34, so that the bolt 27 approaches the threaded hole of the coupling external gear ring sleeve 7, and lock the bolt 27 with this threaded hole.

[0050] Height adjustment: Slide the second sliding seat 40 and rotate the second adjusting lead screw 43 at the same time, so that the first roller 44 is located above the outer side wall of the internal gear sleeve.

[0051] Position fine-tuning and meshing preparation: After the above installation and positioning steps are completed and the stepped column 33 and the bolt 27 are both connected to the external gear ring sleeve 7, adjust the downward extension amounts of the second telescopic sleeve 42 and the third telescopic sleeve 21 respectively. Adjust until the second roller 23 falls on the outer side wall position of the internal gear sleeve and the first roller 44 falls on the outer side wall position of the internal gear sleeve. At this time, it is observed that the external gear ring sleeve 7 is lifted and its axis line coincides with the axis line of the internal gear ring sleeve 6 as much as possible. Then observe the relative movement of the external teeth and the internal teeth. Use the two pairs of rollers to play a rolling support role at the outer diameter, and drive the external gear ring sleeve 7 to achieve circumferential adjustment by slightly pushing the base 20;

[0052] Meshing realization step: When it is observed that the tooth surface positions of the two teeth are close to the meshing state, rotate the transverse lead screw 50. This will cause the second sliding seat 40 to move towards the first sliding seat 30, thereby generating a clamping torque between the first sliding seat 30 and the second base 20. Utilize the elastic characteristics of the spring 52 to ensure that this clamping torque is not too large, so as to avoid over-squeezing the external gear sleeve and the internal gear sleeve in the misaligned state and preventing them from moving. Then slightly adjust the circumferential movement of the base 20 again. With the action of the elastic clamping torque, when the external teeth and the internal teeth of the coupling reach the exactly meshing state, the external gear ring sleeve 7 will be smoothly pressed into the internal gear ring sleeve 6, and finally a meshing state is formed.
