Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission parts, in particular to an output driving gear. Background Art
[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. At the same time, driving gears are a commonly used gear. The existing output driving gears need to mesh with the driven gears during operation, which causes the teeth of the driving gears to wear out during operation, thereby affecting the transmission between the gears. At this time, the gears can only be replaced, but the cost of replacing the entire gear is too high, and resources are wasted. Utility Model Content
[0003] Therefore, in view of the above problems, the utility model provides an output driving gear which is convenient for replacing gear teeth.
[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is to provide an output driving gear, including a gear body, an axial hole opened on the gear body, and a keyway arranged in the axial hole for connecting with a transmission shaft, wherein the gear body is provided with a gear tooth device for meshing with other gears and capable of being disassembled;
[0005] The gear device comprises: a fixing ring arranged outside the gear body, a plurality of gear teeth arranged on the fixing ring, and a clamping device arranged between the fixing ring and the gear body;
[0006] The engaging device comprises: a sliding channel penetrating through the gear body and the fixing ring, a fixing rod slidably arranged in the sliding channel, and a limit block arranged on the fixing rod, and a positioning device for preventing the fixing ring from rotating is also arranged between the fixing ring and the gear body;
[0007] The positioning device comprises: at least one limiting strip arranged on the gear body, and a limiting groove provided on the fixing ring and used for matching and positioning with the limiting strip.
[0008] A further improvement is that a stabilizing device for enhancing the connection stability between the gear body and the fixing ring is also provided on the gear body.
[0009] A further improvement is that the stabilizing device comprises a stabilizing layer disposed on the gear body and between the gear body and the fixing ring, wherein the stabilizing layer avoids the limit strip.
[0010] A further improvement is that the stabilizing layer is a rubber layer.
[0011] A further improvement is that a rebound device is provided between the fixing rod and the sliding channel to facilitate disassembly.
[0012] A further improvement is that the rebound device comprises an elastic channel opened on the sliding channel, and a spring sleeved on the fixing rod, one end of which resists the limit block and the other end resists the bottom of the elastic channel.
[0013] A further improvement is that: a countersunk hole is provided on the keyway for the limit block to avoid the gear key.
[0014] The advantages and beneficial effects of the utility model are:
[0015] The structure is simple and easy to use. It is convenient to disassemble and replace the gear teeth on the outside of the gear body, which is prone to wear during use, thereby avoiding the waste of resources by directly replacing the gears, saving use costs, improving economic benefits, and saving social resources. The hardness of the external gear teeth can be different from that of the gear body, which is convenient for users to match according to actual needs and further save use costs.

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0020] like Figure 1-Figure 2 As shown, an output driving gear includes a gear body 1, an axial hole 2 opened on the gear body 1, and a keyway 3 arranged in the axial hole 2 for connecting with a transmission shaft. The gear body 1 is provided with a gear tooth 5 device for meshing with other gears and capable of being disassembled.
[0021] In order to facilitate the installation and replacement of the gear teeth 5, the gear tooth device includes: a fixed ring 4 arranged on the outside of the gear body 1, a plurality of gear teeth 5 arranged on the fixed ring 4, and a clamping device arranged between the fixed ring 4 and the gear body 1. The clamping device includes: a sliding channel 6 that runs through the gear body 1 and the fixed ring 4, a fixed rod 7 that can be slidably arranged in the sliding channel 6, and a limit block 8 arranged on the fixed rod 7. A positioning device for preventing the fixed ring 4 from rotating is also provided between the fixed ring 4 and the gear body 1. The positioning device includes: at least one limit strip 9 arranged on the gear body 1, and a limit groove 10 opened on the fixed ring 4 for matching and positioning with the limit strip 9.
[0022] In order to enhance the engagement stability, the fixing rod 7 and the sliding channel 6 are in an interference fit, and the limiting strip 9 and the limiting groove 10 are also in an interference fit.
[0023] In order to improve the connection stability between the gear body 1 and the gear tooth 5 device and reduce shaking, the gear body 1 is also provided with a stabilizing device for enhancing the connection stability between the gear body 1 and the fixing ring 4. The stabilizing device includes: a stabilizing layer 11 arranged on the gear body 1 and located between the gear body 1 and the fixing ring 4, the stabilizing layer 11 avoids the limit strip 9, and the stabilizing layer 11 is a rubber layer.
[0024] In order to save effort when removing the fixing rod 7 and improve the convenience of disassembling the gear 5 device, a rebound device for easy disassembly is also provided between the fixing rod 7 and the sliding channel 6. The rebound device includes: an elastic channel 12 opened on the sliding channel 6, and a spring 13 which is sleeved on the fixing rod 7 at one end and resists the limit block 8 at the other end and resists the bottom of the elastic channel 12.
[0025] In order to facilitate the installation of the gear key, a countersunk hole 14 is provided on the keyway 3 for the limit block 8 to avoid the gear key.
[0026] Working principle: During installation, align the limiting groove 10 on the fixing ring 4 with the limiting strip 9, so that the fixing ring 4 is sleeved on the gear body 1, and then the spring 13 is sleeved on the fixing rod 7 and inserted into the sliding channel 6 to complete the installation of the gear 5 device.
[0027] When the gear 5 is damaged, the gear is removed, so that the other side of the sliding channel 6 pushes the fixing rod 7. At this time, under the action of the spring 13, the user can push the fixing rod 7 out of the sliding channel 6 with less effort to release the engagement between the gear device and the gear body 1, and then remove the fixing ring 4 to complete the disassembly and replace the gear device.
