Description

Technical Field

[0001] This utility model belongs to the field of bevel gear technology, and specifically relates to an easy-to-disassemble bevel gear structure. Background Technology

[0002] A bevel gear is a type of gear used for transmission between intersecting shafts. The included angle between the two shafts is typically 90°, but can be less than 90°. Compared to cylindrical gears, bevel gears can change the direction of transmission. Current bevel gear structures generally include components such as a bearing housing, bearing, shaft, bushing, washer, and bevel gear body. Disassembly and assembly require disassembling and reassembling each component—bevel gear, bearing, bushing, etc.—at one end of the shaft, which is cumbersome and inefficient. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an easy-to-disassemble bevel gear structure.

[0004] The objective of this utility model can be achieved through the following technical solution: an easily detachable bevel gear structure, comprising a bevel gear disk and a gear shaft seat;

[0005] A ring-shaped conical gear ring is formed on one side of the bevel gear disk. A through hole is opened in the center of the disk surface inside the conical gear ring. A number of through screw holes are evenly opened in the circumferential direction between the through hole and the inner edge of the conical gear ring.

[0006] The gear shaft seat has several connecting screw holes on the side facing the bevel gear disk, corresponding to the screw holes on the disk surface. The screw holes on the disk surface and the connecting screw holes are fixedly connected from front to back by gear disk screws.

[0007] The gear shaft seat has a through hole at its center that is coaxial with the through hole on the disc surface. On one side of the through hole, there is a separate open deformation groove on the inner wall of the gear shaft seat. The gear shaft seat has two fixing screw slots at the top of the open deformation groove. Each slot has a shaft fixing screw hole that is perpendicular to the open deformation groove at the bottom. Shaft fixing screws are installed in the shaft fixing screw holes.

[0008] In the above-mentioned easy-to-disassemble bevel gear structure, the screw hole on the disc surface is a composite through hole, with screw head seats of larger diameter symmetrically opened at both ends, and the screw head seats are correspondingly engaged with the screw heads of the gear disc screws; a screw seat of smaller diameter is opened in the middle, and the screw seat is penetrated by the screw of the gear disc screw, so that the bevel gear disc can be installed in reverse direction.

[0009] In the aforementioned easy-to-disassemble bevel gear structure, a structural block is formed on the front side wall of the gear shaft seat around the connecting screw hole.

[0010] In the above-mentioned easy-to-disassemble bevel gear structure, the number of screw holes on the disc, connecting screw holes, structural blocks and gear disc screws are consistent and should be no less than 2, preferably 4.

[0011] In the above-mentioned easy-to-disassemble bevel gear structure, the bearing through hole has a deformation buffer groove on the inner wall of the gear bearing on the other side opposite to the open deformation groove.

[0012] Compared with the prior art, the easy-to-disassemble bevel gear structure provided by this utility model does not require the installation of too many parts when connected to the rotating shaft. The rotating shaft is simply inserted into the through hole of the shaft seat from back to front, and then the open deformation groove is locked by the shaft fixing screw. The disassembly and assembly process is simple and greatly improves the efficiency of disassembly and assembly. By setting the gear shaft seat on the rear side of the bevel gear disk and connecting it with the gear disk screw, the bevel gear disk can be installed in reverse according to the actual meshing requirements, which improves the practical flexibility.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1 to 4 As shown, this easy-to-disassemble bevel gear structure includes a bevel gear disk 100 and a gear shaft seat 200. The modular design of the gear shaft seat 200 and the bevel gear disk 100 simplifies the overall disassembly and assembly process.

[0020] One side edge of the bevel gear disk 100 forms an annular conical gear ring 110 for meshing and transmission with another bevel gear. A through-hole 130 is formed at the center of the inner side of the conical gear ring 110 for a rotating shaft to pass through. Four through-holes 120 are evenly distributed circumferentially on the disk surface between the through-hole 130 and the inner edge of the conical gear ring 110. Each screw hole 120 is a composite through-hole, with larger-diameter screw head seats 121 symmetrically positioned at both ends and a smaller-diameter screw seat 122 in the middle. The screw head of the gear disk screw 140 is embedded in the screw head seat 121, and the screw passes through the screw seat 122, allowing the bevel gear disk 100 to be rotated for reverse installation (e.g., ...). Figure 4 ).

[0021] The gear shaft seat 200 has four connecting screw holes 240 on the side facing the bevel gear disk 100, corresponding to the disk surface screw holes 120. The connecting screw holes 240 have raised structural blocks 241 around their periphery to enhance the connection strength. Gear disk screws 140 pass through the disk surface screw holes 120 and connecting screw holes 240 from front to back to fix both.

[0022] The gear shaft seat 200 has a through hole 210 at its center, which is coaxial with the through hole 130 on the disc surface. An open deformation groove 211 is formed on one inner wall of the through hole 210, and an arc-shaped deformation buffer groove 212 is formed on the other inner wall. The gear shaft seat 200 above the open deformation groove 211 has two fixing screw slots 220, and a shaft fixing screw hole 221 is formed at the bottom of the slot. The shaft fixing screw 230 is installed inside. The open deformation groove 211 and the shaft fixing screw 230 cooperate to realize the quick locking of the bevel gear and the rotating shaft.

[0023] The installation and use process of this utility model is as follows:

[0024] 1. Connection between bevel gear disk and gear shaft seat: Align the screw holes 120 on the surface of the bevel gear disk 100 with the connecting screw holes 240 of the gear shaft seat 200, and fix them with gear disk screws 140. Depending on the transmission direction requirements, the bevel gear disk 100 can be flipped, and reverse installation can be achieved using the composite through holes.

[0025] 2. Shaft fixing: Insert the shaft from back to front into the shaft seat through hole 210, tighten the shaft fixing screw 230, so that the open deformation groove 211 is closed by pressure, clamping the shaft. The deformation buffer groove 212 can relieve deformation stress and prevent the gear shaft seat 200 from cracking.

[0026] 3. Disassembly process: During disassembly, simply loosen the shaft fixing screw 230 to release the shaft and unscrew the gear disk screw 140 to separate the bevel gear disk 100 from the gear shaft seat 200. There is no need to disassemble bearings or other components.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0028] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
