Abstract
Description
Technical Field
[0001] The utility model relates to the field of transmission devices, in particular to a cylindrical gear transmission arc rack structure. Background Art
[0002] The cylindrical gear transmission arc rack structure is a special mechanical transmission method, which is widely used in situations where precise linear motion and rotational motion conversion is required. It is suitable for achieving efficient and precise motion control in a limited space. When the drive device rotates the gear shaft, the cylindrical teeth engage with the arc rack, thereby converting the rotational motion into linear motion along an arc path. Conversely, if a linear force is applied to the arc rack, the gear shaft will also rotate. However, during the long-term movement of the gear shaft, the cylindrical teeth will wear, which may cause the gear shaft to loosen and fall off the arc rack, hindering the normal operation of the production or transportation steps.
[0003] In order to solve the above problems, a cylindrical gear transmission arc rack structure is developed. Utility Model Content
[0004] In order to overcome the disadvantage that the cylindrical teeth of the gear shaft will wear out during long-term movement, which may cause the gear shaft to loosen and fall off from the arc rack, thereby hindering the normal operation of production or transportation steps, the utility model provides a cylindrical gear transmission arc rack structure.
[0005] The technical solution of the utility model is: a cylindrical gear transmission arc rack structure, including an arc rack, guide grooves are opened on the front and rear sides of the arc rack, a gear shaft is slidably connected to the arc rack, and limit grooves are provided on the outer sides of the front and rear parts of the gear shaft, a plurality of cylindrical teeth are connected between the front and rear sides of the gear shaft, the cylindrical teeth are meshed with the arc rack, a rotating shaft is provided on the gear shaft, a fastener is connected between the transmission shaft and the gear shaft, a connecting ring is rotatably connected to the limit groove, the lower side of the connecting ring is connected to a mounting piece, and a limiting block is connected to the mounting piece, the inner side of the limiting block is a hemispherical structure, and the inner side of the limiting block is slidably connected to the guide groove on the arc rack.
[0006] In a preferred embodiment of the present invention, a sleeve is further included, and the sleeve is slidably connected to the rotating shaft.
[0007] In a preferred embodiment of the present invention, a plurality of mounting holes are formed on the arc-shaped rack.
[0008] In a preferred embodiment of the present invention, a limiting piece is provided on the cylindrical teeth.
[0009] In a preferred embodiment of the present invention, the rotating shaft is a hollow structure.
[0010] In a preferred embodiment of the present invention, the front diameter of the rotating shaft is larger than the rear diameter.
[0011] By adopting the above technical solution, compared with the existing technology, the utility model has the following advantages:
[0012] The utility model installs the connecting ring on the limiting groove of the gear shaft, and uses the limiting block to be placed in the guide groove on the arc-shaped rack, so that the gear shaft drives the limiting block to slide on the guide groove during the rotation process, thereby limiting the gear shaft, making the gear shaft more stable during the movement, thereby preventing the gear shaft from falling off the arc-shaped rack and ensuring the smooth progress of the production or transportation steps.

[0018] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.
[0019] A cylindrical gear transmission arc rack structure, such as Figures 1-4As shown, it includes an arc-shaped rack 1, a plurality of mounting holes are opened on the arc-shaped rack 1, and guide grooves are opened on the front and rear sides of the arc-shaped rack 1, and a gear shaft 2 is slidably connected to the arc-shaped rack 1. Limit grooves are provided on the outer sides of the front and rear parts of the gear shaft 2, and a plurality of cylindrical teeth 3 are connected between the front and rear sides of the gear shaft 2. A limit piece is provided on the cylindrical tooth 3, and the cylindrical teeth 3 are meshed with the arc-shaped rack 1. A rotating shaft 4 is provided on the gear shaft 2, and the rotating shaft 4 is a hollow structure. The front diameter of the rotating shaft 4 is larger than the rear diameter. A sleeve 5 is slidably connected to the rotating shaft 4, and a fastener 6 is connected between the transmission shaft and the gear shaft 2. A connecting ring 7 is rotatably connected to the limit groove, and a mounting piece 9 is connected to the lower side of the connecting ring 7. A limiting block 8 is connected to the mounting piece 9. The inner side of the limiting block 8 is a hemispherical structure, and the inner side of the limiting block 8 is slidably connected to the guide groove on the arc-shaped rack 1.
[0020] It should be noted that the cylindrical gear transmission arc rack structure is a special mechanical transmission method, which is widely used in situations where precise linear motion and rotational motion conversion is required. It is suitable for achieving efficient and precise motion control in a limited space. When the driving device rotates the gear shaft 2, the cylindrical teeth 3 engage with the arc rack 1, thereby converting the rotational motion into linear motion along an arc path. Conversely, if a linear force is applied to the arc rack 1, the gear shaft 2 will also rotate accordingly. However, during the long-term movement of the gear shaft 2, the cylindrical teeth 3 will wear, which may cause the gear shaft 2 to loosen and fall off from the arc rack 1, hindering the normal operation of the production or transportation steps. The connecting ring 7 can be installed on the limit groove of the gear shaft 2, and the limit block 8 can be placed in the guide groove on the arc rack 1, so that during the rotation of the gear shaft 2, the limit block 8 drives the slide on the guide groove, thereby limiting the gear shaft 2, making the gear shaft 2 more stable during movement, thereby preventing the gear shaft 2 from falling off the arc rack 1 and ensuring the smooth progress of the production or transportation steps.
[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
