Description

Technical Field

[0001] This invention belongs to the field of transmission device testing technology, specifically relating to a gear shaft parallel alignment device for gear transmission. Background Technology

[0002] During operation, the gear shaft is subjected to pressure, which may cause it to deform. This can result in the meshing gears not meeting the required connection standards, potentially leading to vibration and tooth skipping during operation. Deformation of the gear shaft during use necessitates disassembly for bending correction, a time-consuming process that cannot be performed quickly online. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by the present invention is: how to provide a gear shaft parallel alignment device for gear transmission to solve the problems mentioned in the background art.

[0005] (II) Technical Solution

[0006] To solve the above technical problems, the present invention provides a gear shaft parallel alignment device for gear transmission. The device includes: a bracket 1, on both sides of the bracket 1 are symmetrically arranged sleeves 2, and the sidewalls of the sleeves 2 are slidably connected to the bracket 1 through two sliding rods 3 fixedly connected to them, and the sliding rods 3 of the two sleeves 2 are staggered.

[0007] The bracket 1 has a central gear 5 at its center. Each sleeve 2 has a rack 4 on the inner side of a slide rod 3 near the central gear 5. The rack 4 meshes with the central gear 5, and the central gear 5 is on the same straight line as the center of the two sleeves 2.

[0008] A torque sensor 6 is connected to the central gear 5.

[0009] The sleeve 2 consists of two detachable semi-cylinders, one of which is connected to two sliding rods 3 in the middle. The two semi-cylinders are fixed together by bolts 21 to form a complete cylinder.

[0010] The sleeve 2 has multiple sets of pulleys 7 that can slide along the axial direction of the sleeve 2, which are distributed circumferentially on the inner wall of the sleeve 2.

[0011] Each set of pulleys 7 is rotatably distributed on a connecting plate 71, and each connecting plate 71 is hinged to the inner wall of the sleeve 2 by two parallel connecting rods 72.

[0012] The connecting rod 72 has a groove 74 in the middle. The grooves 74 of the two connecting rods 72 corresponding to the same connecting plate 71 are connected to the same adjusting rod 73 by sliding pins 75. The adjusting rod 73 is slidably connected to the inner wall of the sleeve 2. That is, by sliding the adjusting rod 73 up and down, the position of the sliding pin 75 in the groove 74 is changed, which drives the connecting rod 72 to rotate, so that the connecting plate 71 moves closer to or away from the center of the sleeve 2, thereby changing the radius of the pulley 7 distribution so that it can fit into the gear shaft.

[0013] One end of each of the adjusting rods 73 is fixed to an annular pressure plate 8, which is located outside the end face of the sleeve 2.

[0014] A spring 9 is provided between the end faces of the pressure plate 8 and the sleeve 2 in this direction. In its natural state, the spring 9 causes the pulley 7 to move to the position closest to the center of the sleeve 2.

[0015] The pressure plate 8 corresponds to the sleeve 2. The pressure plate 8 is also a complete ring composed of two semi-circular rings, and the two semi-circular rings are fitted together by a tongue 81.

[0016] Among them, the bracket 1 is fixed with bonding tiles 10 on both sides near the sleeve 2. The bonding tiles 10 have the same curvature as the outer wall of the sleeve 2, and the sliding rod 3 is slidably connected to the bonding tiles 10, so that the sleeve 2 can be completely bonded to the bracket 1.

[0017] The outer wall of the sleeve 2 is provided with a sensing plate 11 at the position corresponding to the bonding tile 10. The sensing plate 11 can generate a corresponding signal when the sleeve 2 and the bonding tile 10 are bonded together.

[0018] In specific implementation, the semi-cylinders of the sleeves 2 at both ends of the bracket 1 are disassembled, the extension length of the slide rod 3 is adjusted so that the two sleeves 2 are respectively fitted onto the two gear shafts, and the sleeves 2 are closed by bolts 21 to form a complete cylinder. At the same time, the two semi-circular rings of the two pressure plates 8 are fitted together by the tongue 81.

[0019] Under the action of spring 9, each pulley 7 can fit into the gear shaft with a certain elasticity. The bracket 1 is slowly moved from one end of the gear shaft to the other end. The torque sensor 6 records the torque generated on the central gear 5, so as to correct the distance change of the two sleeves 2 during the sliding process and thus correct the parallelism of the gear shaft.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In this invention, pulleys enable two sleeves to slide along two gear shafts respectively, and a torque sensor records the torque generated on the central gear, thereby enabling the calibration of the distance change between the two sleeves during the sliding process to calibrate the parallelism of the gear shafts.

[0023] In this invention, the two detachable sleeves can be fitted into the gear shaft without passing through the end face of the gear shaft, so as to facilitate online parallel calibration.

[0024] In this invention, when the sleeve is fitted into the gear shaft and pressed against the pulley, the spring is compressed, allowing the pulley to fit into the gear shaft with a certain elasticity, ensuring the concentricity of the sleeve and the gear shaft and reducing the vibration generated during sliding.

[0029] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0030] like Figures 1-3 As shown in the embodiment of the present invention, a gear shaft parallel alignment device for gear transmission is provided, including a bracket 1. Sleeves 2 are symmetrically arranged on both sides of the bracket 1. The sidewalls of the sleeves 2 are slidably connected to the bracket 1 by two sliding rods 3 fixedly connected to them, and the sliding rods 3 of the two sleeves 2 are staggered.

[0031] The bracket 1 has a central gear 5 at its center. Each sleeve 2 has a rack 4 on the inner side of a slide rod 3 near the central gear 5. The rack 4 meshes with the central gear 5, and the central gear 5 is on the same straight line as the center of the two sleeves 2.

[0032] In this embodiment, a torque sensor 6 is connected to the central gear 5, thereby reflecting the change in the distance between the two sleeves 2 by calibrating the rotation of the central gear 5 through the torque sensor 6.

[0033] In this embodiment, the sleeve 2 is composed of two detachable semi-cylinders, the middle of which is connected to two sliding rods 3. The two semi-cylinders are fixed together by bolts 21 to form a complete cylinder, so that the sleeve 2 can be fitted into the gear shaft without passing through the end face of the gear shaft, so as to facilitate online parallel calibration.

[0034] In this embodiment, the inner wall of the sleeve 2 is circumferentially distributed with multiple sets of pulleys 7 that can slide along the axial direction of the sleeve 2. The pulleys 7 enable the two sleeves 2 to slide along the two gear shafts to be aligned in parallel, and the torque sensor 6 records the torque generated on the central gear 5, thereby enabling the correction of the distance change between the two sleeves 2 during the sliding process to correct the parallelism of the gear shafts.

[0035] In this embodiment, each set of pulleys 7 is rotatably distributed on a connecting plate 71, and each connecting plate 71 is hinged to the inner wall of the sleeve 2 by two parallel connecting rods 72.

[0036] In this embodiment, a groove 74 is provided in the middle of the connecting rod 72. The grooves 74 of the two connecting rods 72 corresponding to the same connecting plate 71 are connected to the same adjusting rod 73 by sliding pins 75. The adjusting rod 73 is slidably connected to the inner wall of the sleeve 2. That is, by sliding the adjusting rod 73 up and down, the position of the sliding pin 75 in the groove 74 is changed, which drives the connecting rod 72 to rotate, so that the connecting plate 71 moves closer to or away from the center of the sleeve 2, thereby changing the radius of the pulley 7 distribution so that it can fit into the gear shaft.

[0037] In this embodiment, one end of each adjusting rod 73 is fixed to an annular pressure plate 8, which is located outside the end face of the sleeve 2.

[0038] In this embodiment, a spring 9 is provided between the end faces of the pressure plate 8 and the sleeve 2 in this direction. In its natural state, the spring 9 causes the pulley 7 to move to the position closest to the center of the sleeve 2. That is, when the sleeve 2 is fitted into the gear shaft and presses against the pulley 7, the spring 9 is compressed, so that the pulley 7 can fit into the gear shaft with a certain elasticity, ensuring the concentricity of the sleeve 2 and the gear shaft and reducing the vibration generated during the sliding process.

[0039] In this embodiment, the pressure plate 8 corresponds to the sleeve 2. The pressure plate 8 is also a complete ring composed of two semi-circular rings, and the two semi-circular rings are fitted together by the tongue 81.

[0040] In this embodiment, the bracket 1 is fixed with bonding tiles 10 on both sides near the sleeve 2. The bonding tiles 10 have the same curvature as the outer wall of the sleeve 2, and the slide rod 3 is slidably connected to the bonding tiles 10, so that the sleeve 2 can be completely bonded to the bracket 1.

[0041] The outer wall of the sleeve 2 is provided with a sensing element 11 at the position corresponding to the bonding tile 10. The sensing element 11 can generate a corresponding signal when the sleeve 2 and the bonding tile 10 are bonded together. When the sleeve 2 and the bonding tile 10 are bonded together, the parallel calibration data is invalid.

[0042] In practice, the semi-cylinders of the sleeves 2 at both ends of the bracket 1 are disassembled. After adjusting the extension length of the slide rod 3 so that the two sleeves 2 are respectively fitted onto the two gear shafts, the sleeves 2 are closed with bolts 21 to form a complete cylinder. At the same time, the two semi-circular rings of the two pressure plates 8 are fitted together with the tongue 81.

[0043] Under the action of spring 9, each pulley 7 can fit into the gear shaft with a certain elasticity. The bracket 1 is slowly moved from one end of the gear shaft to the other end. The torque sensor 6 records the torque generated on the central gear 5, so as to correct the distance change of the two sleeves 2 during the sliding process and thus correct the parallelism of the gear shaft.

[0044] 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 technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
