DETAILED DESCRIPTION

[0017] The present invention can be explained in detail by the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] A locking disc assembly structure for power output in the middle of a transmission shaft, which is used for fixedly connecting an assembled transmission shaft 1 to a power output structural member 2 without changing any of its existing structures; the locking disc assembly 3 comprises a locking disc inner ring 3.2, a locking disc middle ring, and a locking disc outer ring 3.1, which are nested in sequence from the inside to the outside, and conical surfaces are provided between the mating surfaces; the locking disc assembly 3 is arranged in an annular space between the transmission shaft 1 and the power output structural member 2, and the locking disc middle ring is moved by bolts, and the conical surfaces between the mating surfaces are used to change the inner diameter of the locking disc inner ring 3.2 and the outer diameter of the locking disc outer ring 3.1 at the same time, thereby achieving a fixed connection between the transmission shaft 1 and the power output structural member 2. ; In the locking disk assembly structure of the present invention, one of the structural parts must undergo axial displacement to achieve the connection between the transmission shaft 1 and the power output structural part 2, and the contact pressure and friction between the conical surfaces of the two components that undergo axial displacement are very large, which may cause adhesion and damage to the contact surfaces between the two components that undergo axial displacement; the reason for providing the locking disk inner ring 3.2, the locking disk middle ring, and the locking disk outer ring 3.1 is to avoid contact between the component that undergoes axial displacement (locking disk middle ring) and the transmission shaft 1 and the power output structural part 2, thereby preventing damage to the outer cylindrical surface of the transmission shaft 1 or the inner hole surface of the power output structural part 2 during assembly, thereby ensuring the overall stability and reliability of the original transmission structure of the transmission shaft 1.

[0019] Furthermore, the power output structural member 2 and the locking plate assembly 3 are both petal-type structures; under the premise that any equipment connected to the original transmission shaft 1 is not allowed to be disassembled, both ends of the transmission shaft 1 are closed, and when the power output structural member 2 and the locking plate assembly 3 are complete annular structures, they cannot be installed. After the power output structural member 2 and the locking plate assembly 3 are set as petal structures, they can be installed in the middle of the transmission shaft 1 in an assembled manner, thereby solving the connection and assembly problem of the power output structural member 2, the locking plate assembly 3 and the transmission shaft 1 with both ends closed; The power output structure 2 and the locking plate assembly 3 are divided into more than 2 petals; usually, the power output structure 2 and the locking plate assembly 3 are divided into two petals, but in some cases, for example, the power output structure 2 and the locking plate assembly 3 are too large in size and weight, and the on-site construction space is too small to use engineering machinery to assist in construction. At this time, the power output structure 2 and the locking plate assembly 3 can be divided into three petals or more to reduce the size and weight of each petal, thereby facilitating construction.

[0020] Furthermore, the locking disk assembly 3 comprises a locking disk outer ring 3.1, a locking disk inner ring 3.2, a locking disk middle ring A3.3, and a locking disk middle ring B3.4; the inner circumferential surface of the locking disk outer ring 3.1 is provided with inner conical surfaces 3.1.1 on both sides; the outer circumferential surface of the locking disk inner ring 3.2 is provided with outer conical surfaces 3.2.1 on both sides; the inner and outer circumferential surfaces of the locking disk middle ring A3.3 are provided with inner conical surfaces 3.3.1 of the middle ring A and outer conical surfaces 3.3.2 of the middle ring A respectively; the inner and outer circumferential surfaces of the locking disk middle ring B3.4 are provided with inner conical surfaces 3.4.1 of the middle ring B and outer conical surfaces 3.4.2 of the middle ring B respectively; the locking disk inner ring 3. 2 is arranged on the outer cylindrical surface of the transmission shaft 1, the outer ring 3.1 of the locking plate is arranged on the outside of the inner ring 3.2 of the locking plate, and the middle ring A3.3 of the locking plate and the middle ring B3.4 of the locking plate are arranged in the conical annular space between the inner ring 3.2 of the locking plate and the outer ring 3.1 of the locking plate, and are connected by a plurality of bolts; when the bolts are tightened, the middle ring A3.3 of the locking plate and the middle ring B3.4 of the locking plate move axially, and the inner and outer diameters of the locking plate assembly 3 are changed at the same time by using the conical surface, so as to realize the power connection between the power output structure 2 and the transmission shaft 1; this design of splitting the middle ring of the locking plate into two symmetrical structures can Under the condition that the width of the power output structure 2 is certain, the width of the conical surface of the outer ring 3.1 of the locking plate, the inner ring 3.2 of the locking plate and the middle ring of the locking plate can be shortened. Correspondingly, the conical surfaces of the outer ring 3.1 of the locking plate, the inner ring 3.2 of the locking plate and the middle ring of the locking plate can cooperate with each other under the premise of adopting a larger taper, and the wall thickness of the large-aperture end of the outer ring 3.1 of the locking plate and the inner ring 3.2 of the locking plate will not be too thin; and after the conical surface adopts a larger taper, it can prevent the locking plate middle ring from sticking to the conical surfaces of the outer ring 3.1 of the locking plate and the inner ring 3.2 of the locking plate during the locking displacement process. It is self-locking, so that the locking plate assembly can still be reused when the power output structural member 2 is disassembled, repaired or replaced; in addition, after the locking plate middle ring is split into two symmetrical structures, the outward tightening locking force of the locking plate outer ring 3.1 and the locking plate inner ring 3.2 can be made more uniform in the axial direction, which can ensure the reliability of the connection structure between the transmission shaft 1 and the power output structural member 2 and a greater transmission torque; the locking plate assembly 3 of this structure has been tested, and the maximum transmission torque between the transmission shaft 1 and the power output structural member 2 can exceed the rated design transmission torque by more than 6 times.

[0021] Furthermore, the locking plate assembly 3 includes a locking plate outer ring 3.1, a locking plate inner ring 3.2, a locking plate middle ring 3.5, and an end ring 3.6; the inner circumferential surface of the locking plate outer ring 3.1 is provided with an inner conical surface 3.1.1; the outer circumferential surface of the locking plate inner ring 3.2 is provided with an outer conical surface 3.2.1; the inner and outer circumferential surfaces of the locking plate middle ring 3.5 are respectively provided with a middle ring inner conical surface 3.3.1 and a middle ring outer conical surface 3.3.2; the locking plate inner ring 3.2 is arranged on the outer circumferential surface of the transmission shaft 1, and the locking plate outer ring 3.1 is provided with On the outside of the locking plate inner ring 3.2, the locking plate middle ring 3.5 is arranged between the locking plate inner ring 3.2 and the locking plate outer ring 3.1, and the end ring 3.6 is arranged on the end surface of the locking plate outer ring 3.1 and the locking plate inner ring 3.2 on one side. The locking plate middle ring 3.5 and the end ring 3.6 are connected by a plurality of bolts; when the bolts are tightened, the locking plate middle ring 3.5 moves axially, and the conical surface is used to change the inner and outer diameters of the locking plate assembly 3 at the same time, so that the power output structure 2 is dynamically connected to the transmission shaft 1.

[0022] Furthermore, two sets of locking plate assemblies 3 are provided; when the width of the power output structure 2 is larger, its load torque requirement is also larger. By providing two sets of locking plate assemblies 3, a larger transmission torque can be provided to meet the larger load torque requirement of the power output structure 2.

[0023] Furthermore, a power output structural component positioning ring 2.1 is provided on the inner circumferential surface of the power output structural component 2; the power output structural component positioning ring 2.1 is used for positioning the locking disc assembly 3 in the axial direction.

[0024] Furthermore, an outer ring positioning ring 3.1.2 is provided on the inner circumferential surface of the locking disk outer ring 3.1, and an inner ring positioning ring 3.2.2 is provided on the outer circumferential surface of the locking disk inner ring 3.2; the outer ring positioning ring 3.1.2 and the inner ring positioning ring 3.2.2 are both used for positioning the locking disk center ring to be locked in place, so as to avoid asymmetric positions of the locking disk center rings on both sides after the locking disk center ring is locked, which may cause uneven locking force of the locking disk assembly 3 on the axis; it is additionally explained that after the outer ring positioning ring 3.1.2 and the inner ring positioning ring 3.2.2 are provided, the interference fit of the conical surfaces between the locking disk outer ring 3.1, the locking disk inner ring 3.2 and the locking disk center ring must be accurately calculated, and the machining accuracy must be ensured at the same time, otherwise the locking disk center ring may not be able to be locked in place, or the transmitted torque may not meet the design requirements after being locked in place.

[0025] Furthermore, a plurality of through holes 3.3.3 and ejector threaded holes 3.3.4 are evenly distributed on the end surface of the locking disk center ring A3.3; wherein the through holes 3.3.3 are used to pass the connecting bolts, and wherein the ejector threaded holes 3.3.4 are used to eject the locking disk center ring A3.3 and the locking disk center ring B3.4 by means of ejector screws when the locking disk assembly 3 is disassembled, so as to facilitate the disassembly of the locking disk assembly 3; a plurality of locking threaded holes 3.4.3 are evenly distributed on the end surface of the locking disk center ring B3.4, which are used to engage with the connecting bolts.

[0026] A method for connecting a locking disc assembly structure for power output in the middle of a transmission shaft, wherein the power output structural member 2 and the locking disc assembly 3 directly splice several petals at a set position on the transmission shaft 1 to form a complete output structural member 2 and the locking disc assembly 3; the locking disc middle ring is moved axially by means of a locking bolt, and the inner and outer diameters of the locking disc assembly 3 are changed by means of a conical surface to dynamically connect the power output structural member 2 to the transmission shaft 1; this connection method is suitable for situations where the original connection structures at both ends of the transmission shaft 1 are not allowed to be removed. When this connection method is used, the power output structural member 2 and the locking disc outer ring 3.1, the locking disc inner ring 3.2, and the locking disc middle ring in the locking disc assembly 3 are all petal structures.

[0027] A connection method for a locking disc assembly structure for power output in the middle of a transmission shaft, wherein the power output structural member 2 and the locking disc assembly 3 are both started from one end of the transmission shaft 1 and are movably arranged at a set position of the transmission shaft 1, and the locking disc middle ring is moved axially by a locking bolt, and the inner and outer diameters of the locking disc assembly 3 are changed simultaneously by a conical surface, so as to connect the power output structural member 2 to the transmission shaft 1 dynamically; this connection method is suitable for situations where the original connection structure at one end of the transmission shaft 1 can be removed, and when this connection method is used, the power output structural member 2, the locking disc outer ring 3.1, the locking disc inner ring 3.2, and the locking disc middle ring in the locking disc assembly 3 are usually an integral circular ring structure.

The inner diameter of the locking plate inner ring 3.2 and the outer diameter of the locking plate outer ring 3.1 are changed simultaneously by utilizing the cooperation of the conical surfaces between the locking plate middle ring 3.5 and the locking plate outer ring 3.1 and the locking plate inner ring 3.2, thereby fixing the transmission shaft 1 and the power output structural member 2 together, so that the power output structural member 2 can reliably output the load torque according to the design load requirement.

In this embodiment, the outer ring positioning ring 3.1.2 of the locking disk outer ring 3.1 and the inner ring positioning ring 3.2.2 of the locking disk inner ring 3.2 are not necessary structures.

[0031] In this embodiment, the connection method of the locking plate assembly structure for power output in the middle of the transmission shaft is basically the same as that in the first embodiment; the difference is that: in step two, the two-petal locking plate middle ring A3.3 and the locking plate middle ring B3.4 are spliced ​​on the outer circumferential surface of the locking plate inner ring 3.2; in step four, there is no need to set the two-petal end ring 3.6, but directly pass the connecting bolt through the through hole of the locking plate middle ring A3.3 and the threaded hole of the locking plate middle ring B3.4 to preliminarily complete the assembly of the locking plate assembly 3. Embodiment three:

[0032] See the instruction manual Fig.17 : In this embodiment, the structure of the locking disc assembly 3 is exactly the same as that of the second embodiment; the difference between this embodiment and the second embodiment is that two sets of locking disc assemblies 3 are symmetrically arranged in the annular space between the transmission shaft 1 and the power output structural member 2; in order to cooperate with the positioning of the locking disc assembly 3 arrangement, the power output structural member positioning ring 2.1 is arranged in the middle position of the inner circular surface width direction of the power output structural member 2; In this embodiment, the connection method of the locking plate assembly structure for power output in the middle of the transmission shaft is basically the same as that in the second embodiment; the difference is that two sets of locking plate assemblies 3 are pushed into the annular space between the transmission shaft 1 and the power output structure 2 from both sides of the power output structure 2.

[0033] Another connection method for the locking plate assembly structure for power output in the middle of the transmission shaft is: the power output structural member 2 and the locking plate assembly 3 are both started from one end of the transmission shaft 1 and are moved and set at the set position of the transmission shaft 1. The locking bolt is used to move the middle ring of the locking plate axially, and the inner and outer diameters of the locking plate assembly 3 are changed at the same time by the conical surface to connect the power output structural member 2 to the transmission shaft 1 dynamically; this connection method is suitable for the situation where the original connection structure at one end of the transmission shaft 1 can be removed. When this connection method is used, the power output structural member 2 and the locking plate assembly 3 in the locking plate outer ring 3.1, the locking plate inner ring 3.2, and the locking plate middle ring are usually an integral circular ring structure, but this connection method is also applicable to the output structural member 2 and the locking plate assembly 3 with a petal structure.
