Description

Technical Field

[0001] This utility model relates to the technical field of clutch kits, specifically a splined shaft kit for a high-speed thin strip steel disc shear clutch. Background Technology

[0002] Turret-type disc shears play a crucial role in cold-rolled strip steel production, providing a strong guarantee for producing high-quality and qualified strip steel. Its main function is to connect and disconnect the transmission relationship between two rotating shafts. This clutch operates by using the contact and separation of two discs to achieve the connection and disconnection of the transmission. When the two discs are in close contact, the friction between them causes the two shafts to rotate synchronously, thus achieving transmission; when the two discs separate, the friction disappears, and the transmission relationship between the two shafts is broken.

[0003] However, in existing technologies, traditional disc shear clutch sliding shaft assemblies consist of a jawed sliding sleeve with a keyway, a sliding shaft with a sliding key, and a sliding key. During use, the jawed sliding sleeve and the sliding shaft frequently slide relative to each other, resulting in repeated friction and poor lubrication, which often causes the clutch to jam. Therefore, shearing is required, which severely affects the unit's shearing rate. In addition, the single-sided sliding key causes uneven stress on the clutch sliding shaft assembly. Therefore, we provide a splined shaft assembly for high-speed thin strip steel disc shear clutches. Utility Model Content

[0004] The purpose of this invention is to provide a splined shaft assembly for a high-speed thin strip steel disc shear clutch, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spline shaft assembly for a high-speed thin strip steel disc shear clutch, comprising: an anti-jamming mechanism, the anti-jamming mechanism including a spline shaft body, an involute tooth 1 being provided on the outer side of one end of the spline shaft body, a limiting ring being provided on the outer side of the spline shaft body near the involute tooth 1, six connecting blocks being arranged in a ring array on the outer side of the limiting ring, a piston tube being provided on the side of each of the six connecting blocks near the involute tooth 1, a telescopic rod being provided on the end of each of the six piston tubes away from the connecting blocks, a toothed sliding sleeve being provided on the end of the spline shaft body near the involute tooth 1, an involute tooth 2 being provided on the inner wall of the toothed sliding sleeve that matches the tooth groove of the involute tooth 1, and a connecting mechanism being provided on the end of the spline shaft body away from the toothed sliding sleeve.

[0006] As a further preferred embodiment of this technical solution, the connecting mechanism includes a flange, the inner wall of which is fixedly connected to the outer side of the bearing, and the inner surface of the bearing is fixedly connected to the outer side of the spline shaft body away from the toothed sliding sleeve.

[0007] As a further preferred embodiment of this technical solution, the inner surface of the limiting ring is fixedly connected to the outer side of the spline shaft body near the involute tooth.

[0008] As a further preferred embodiment of this technical solution, the six connecting blocks are all fixedly connected to the outside of the limiting ring on the side closest to the limiting ring.

[0009] As a further preferred embodiment of this technical solution, the end of the piston tube near the connecting block is fixedly connected to the side of the connecting block near the telescopic rod.

[0010] As a further preferred embodiment of this technical solution, the outer surface of the telescopic rod is slidably connected to the inner surface of the piston tube, and the end of the telescopic rod away from the piston tube is fixedly connected to the side of the toothed sliding sleeve near the involute tooth.

[0011] As a further preferred embodiment of this technical solution, the end of the spline shaft body near the first involute tooth is mated inside the toothed sliding sleeve, and the teeth of the second involute tooth mesh with the grooves of the first involute tooth and are slidably connected.

[0012] This utility model provides a splined shaft assembly for a high-speed thin strip steel disc shear clutch, which has the following advantages:

[0013] (1) This utility model improves the hardness and wear resistance of the involute tooth surface by performing carburizing heat treatment on the involute tooth surface of the spline shaft body and the toothed sliding sleeve respectively. The gap between the involute tooth surface of the spline shaft body and the toothed sliding sleeve can accommodate grease to reduce wear during sliding. It avoids the problem of poor lubrication when the toothed sliding sleeve and the spline shaft body slide relative to each other and rub repeatedly, which leads to frequent clutch jamming. It ensures the normal shearing of the disc shear, effectively improves the assembly material yield, and greatly reduces spare parts costs and other additional costs.

[0014] (2) The present invention can fix the spline shaft body assembly on the unit by means of the flange and bearing, which can greatly simplify the installation process. When the spline shaft body needs to be replaced or maintained, the staff can quickly disassemble the flange and bearing assembly without disassembling the whole thing. This convenient design significantly reduces the maintenance cost and downtime of the equipment. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a splined shaft assembly for a high-speed thin strip steel disc shear clutch includes: an anti-jamming mechanism 1, which includes a splined shaft body 11. An involute tooth 12 is formed on the outer side of one end of the splined shaft body 11. A limiting ring 13 is provided on the outer side of the splined shaft body 11 near the involute tooth 12. The inner surface of the limiting ring 13 is fixedly connected to the outer side of the splined shaft body 11 near the involute tooth 12. Six connecting blocks 14 are arranged in a ring array on the outer side of the limiting ring 13. The six connecting blocks 14 are fixedly connected to the outer side of the limiting ring 13 on the side near the involute tooth 12. A piston tube 15 is provided on the side of each of the six connecting blocks 14 near the involute tooth 12. A telescopic rod is provided on the end of each of the six piston tubes 15 away from the connecting block 14. 18. One end of the piston tube 15 near the connecting block 14 is fixedly connected to the side of the connecting block 14 near the telescopic rod 18. A toothed sliding sleeve 16 is provided at one end of the spline shaft body 11 near the involute tooth 12. The outside of the telescopic rod 18 is slidably connected to the inner surface of the piston tube 15. The end of the telescopic rod 18 away from the piston tube 15 is fixedly connected to the side of the toothed sliding sleeve 16 near the involute tooth 12. An involute tooth 17 that matches the tooth groove of the involute tooth 12 is opened on the inner wall of the toothed sliding sleeve 16. One end of the spline shaft body 11 near the involute tooth 12 is mated to the inside of the toothed sliding sleeve 16. The teeth of the involute tooth 17 mesh with the tooth groove of the involute tooth 12 and are slidably connected. A connecting mechanism 2 is provided at one end of the spline shaft body 11 away from the toothed sliding sleeve 16.

[0022] In this embodiment, the device includes a toothed sliding sleeve 16 with involute teeth 17 and a splined shaft body 11 with involute teeth 12. The involute tooth surfaces of the splined shaft body 11 and the toothed sliding sleeve 16 are subjected to carburizing heat treatment to improve the hardness and wear resistance of the involute tooth surfaces. The gap between the involute tooth surfaces of the splined shaft body 11 and the toothed sliding sleeve 16 can accommodate grease to reduce wear during sliding, ensuring normal shearing of the disc shear, effectively improving the assembly yield, and greatly reducing spare parts costs and other additional costs. Therefore, during use, the toothed sliding sleeve 16 and the spline teeth often slide relative to each other, and the teeth of the involute teeth 17 will mesh and slide with the tooth grooves of the involute teeth 12. At the same time, the outside of the telescopic rod 18 will slide inside the piston tube 15 to ensure the stability of the toothed sliding sleeve 16 and the spline teeth during telescopic sliding.

[0023] like Figures 1-4 As shown, the connecting mechanism 2 includes a flange 21, the inner wall of the flange 21 is fixedly connected to the outside of the bearing 22, and the inner surface of the bearing 22 is fixedly connected to the outside of the spline shaft body 11 away from the toothed sliding sleeve 16.

[0024] In this embodiment, the spline shaft body 11 assembly can be fixedly installed on the unit by means of the flange 21 and bearing 22, which can greatly simplify the installation process. As standard components, the flange 21 and bearing 22 can be quickly positioned and fixed during installation, reducing the need for high-precision alignment. When it is necessary to replace or maintain the spline shaft body 11, the staff can quickly disassemble the flange 21 and bearing 22 assembly without disassembling the whole assembly. This convenient design significantly reduces the maintenance cost and downtime of the equipment.

[0025] This utility model provides a splined shaft assembly for a high-speed thin strip steel disc shear clutch, and its working principle is as follows:

[0026] In practical applications, relative sliding frequently occurs between the toothed sliding sleeve 16 and the spline teeth. This sliding action causes the teeth of the involute tooth 17 to mesh with the tooth groove of the involute tooth 12, resulting in sliding. At the same time, the exterior of the telescopic rod 18 will also slide accordingly inside the piston tube 15. This design enables the entire mechanism to achieve smooth movement and effective transmission during operation. The spline shaft body 11 assembly can be fixedly installed on the unit through the flange 21 and bearing 22. When the spline shaft body 11 needs to be replaced or maintained, the operator can quickly disassemble the flange 21 and bearing 22 assembly.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
