Description

Technical Field

[0001] This utility model relates to the field of transmission machinery technology, specifically to a novel carbon fiber precursor drive protection system. Background Technology

[0002] High-performance fibers are a type of special fiber that has a unique ability to withstand external physical and chemical effects. As an important development direction of the chemical fiber industry, they can be divided into two major categories: organic and inorganic.

[0003] In existing carbon fiber production technology, the design of the drive rollers being directly driven by a reducer to the drive shaft has significant flaws: during fiber production, several drive rollers drive multiple filament bundles for drawing and transmission, and a single failure of one of them can cause the entire production line to stop. Unplanned shutdowns generate large amounts of solid waste and create cumbersome subsequent manual fiber drawing processes, resulting in substantial losses. Utility Model Content

[0004] This invention provides a novel carbon fiber precursor drive protection system, the purpose of which is to provide a drive protection system that can reduce the risk of production stoppage when the transmission equipment fails.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A novel carbon fiber precursor drive protection system includes:

[0007] The coupling housing has one end connected to the drive shaft via a frame flange, and the other end connected to the drive reducer via bolts.

[0008] The spline bushing is mounted on the input shaft of the reducer, and the keyway fixing sleeve is mounted on the transmission shaft. A piece of the gear set is installed on the end face of the spline bushing and the keyway fixing sleeve respectively. Power is transmitted through the meshing of the gear sets.

[0009] The coupling housing is provided with a separation connection groove, and the adjusting rod slides through the separation connection groove and is mounted on the splined bushing to limit the displacement of the adjusting rod.

[0010] Furthermore, the spline bushing has a spline structure inside, slides with the input shaft of the reducer, and a compression spring is provided between it and the reducer.

[0011] Furthermore, the spline bushing is equipped with a sliding ring, and the adjusting rod is mounted on the spline bushing via the sliding ring.

[0012] Furthermore, the bite tooth profile of the toothed disc assembly is consistent with the transmission direction.

[0013] Furthermore, a rolling bearing is provided between the keyway fixing sleeve and the coupling housing, and the bearing position is limited by a shaft elastic retaining ring.

[0014] Furthermore, the separation connection groove includes a connection groove and a separation groove. The adjusting rod slides into the connection groove to connect the toothed disc assembly, and the adjusting rod slides into the separation groove, pushing the splined bushing backward to separate the toothed disc assembly.

[0015] Furthermore, the input shaft of the reducer is a splined shaft, which is fixed to the inner bushing of the reducer using a shaft retainer.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] This invention discloses a novel carbon fiber precursor drive protection system. The inclined tooth profile of the crankset combines with a separation connection groove mechanism, allowing the drive shaft to continue rotating even when the reducer fails and stops. The crankset can also be manually and quickly separated from the faulty section, while the remaining transmission units continue to operate. This effectively avoids the drawbacks of traditional designs where a single stop causes a complete shutdown, reducing unplanned downtime, lowering solid waste generation, and reducing manual recovery costs.

[0028] like Figures 1-4 As shown, a novel carbon fiber precursor drive protection system includes: a coupling housing 2, one end of which is connected to a drive shaft 15 via a frame flange 1, and the other end is connected to a transmission reducer 5 via bolts; the coupling housing 2 serves as the core load-bearing structure of the system, realizing the physical connection of the power transmission channel. The input shaft 51 of the reducer 5 is a splined shaft 4, which is fixed to the inner bushing of the reducer 5 using a shaft retainer 6. During transmission, the input shaft 51 of the reducer 5 drives the drive shaft 15 to rotate via a pressure plate assembly, and the drive shaft 15 then drives other components to rotate.

[0029] The spline bushing 3 is mounted on the input shaft 51 of the reducer 5, and the keyway fixing sleeve is mounted on the transmission shaft 15. A piece of the sprocket assembly 8 is mounted on the end face of the spline bushing 3 and the keyway fixing sleeve respectively. Power transmission is achieved through the interlocking of the sprocket assemblies 8. The sprocket assembly 8 is the core power transmission unit, which also has torque transmission and safety clutch functions.

[0030] The coupling housing 2 is provided with a separation connection groove 11, and the adjusting rod 13 is slidably disposed on the spline bushing 3 through the separation connection groove 11 to limit the displacement of the adjusting rod 13.

[0031] The separation connection groove 11 includes a connection groove and a separation groove 112. The adjusting rod 13 slides to the connection groove 111 to connect the crank assembly 8. The adjusting rod 13 slides to the separation groove 112, and the spline bushing 3 pushes backward to separate the crank assembly 8.

[0032] When sliding within the separation groove 11: When the adjusting rod 13 is pushed to the connection groove 111, the compression spring 14 pushes the spline bushing 3, and the gear plate assembly 8 engages; when the adjusting rod 13 moves to the separation groove 112, the spline bushing 3 pushes the compression spring 14, and the pressure plate assembly separates.

[0033] The spline bushing 3 has a spline structure inside and slides with the input shaft 51 of the reducer 5. A compression spring 14 is provided between the bushing and the reducer 5.

[0034] The spline bushing 3 is provided with a sliding ring 12, and the adjusting rod 13 is set on the spline bushing 3 through the sliding ring 12, so that the spline bushing 3 can rotate relative to the adjusting rod 13. The adjusting rod 13 is only used to push the spline bushing 3 to move back and forth along the input shaft 51 of the reducer.

[0035] The bite teeth of the tooth assembly 8 are designed with an inclined angle consistent with the transmission direction to ensure tight meshing during normal transmission. The active tooth assembly drives the passive tooth assembly to rotate. In case of failure, the active tooth assembly does not rotate, but the passive tooth assembly can still rotate.

[0036] A rolling bearing 10 is provided between the keyway retaining sleeve and the coupling housing 2, and the bearing position is limited by a shaft elastic retaining ring 9. This achieves precise positioning of the transmission shaft 15 and radial load support, reducing frictional losses during transmission.

[0037] During normal operation, the input shaft 51 of the reducer drives the transmission shaft 15 to rotate via the sprocket assembly 8. When a fault occurs at the reducer end, the input shaft 51 does not rotate, but the transmission shaft 15 can rotate independently. In this case, the teeth of the sprocket at the transmission shaft 15 rub against the teeth of the sprocket at the reducer end, pushing the teeth of the sprocket at the reducer end backward. In case of equipment failure, the sprocket assembly 8 can also be separated by manually pushing the adjusting rod 13.

[0038] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
