Description
Technical Field
[0001] This invention relates to the field of split gear technology, specifically to a split gear that can be quickly disassembled and assembled. Background Technology
[0002] As a core component for transmitting power and motion in mechanical transmission systems, gears are widely used in various industrial fields such as engineering machinery, automotive gearboxes, machine tool transmission mechanisms, automated production lines, rail transit equipment, and aerospace transmission devices. In actual use scenarios, gears are in a working state of high-speed rotation, alternating load, and continuous meshing friction for a long time. The tooth surface is prone to failure problems such as wear, pitting, tooth breakage, and fatigue cracks. Once a traditional integral gear is partially damaged, the entire gear needs to be disassembled and replaced from the drive shaft. This not only involves a cumbersome disassembly and assembly process but also wastes qualified hub structures, significantly increasing equipment maintenance costs and downtime.
[0003] Although some split gear structures have appeared on the market, they generally suffer from technical defects such as low disassembly and assembly efficiency, poor positioning accuracy, insufficient connection stability, and limited adaptability. 1. Existing split gears mostly use conventional connection methods such as bolts, pins, and interference fits. Installation requires the use of special wrenches, hydraulic tools and other auxiliary equipment. Disassembly requires the removal of fasteners one by one. The operation steps are complicated and it is difficult to achieve quick assembly and disassembly. It cannot meet the needs of rapid on-site repair and efficient maintenance of equipment. Some split gears lack precise guiding and positioning structures. When assembling the gear ring and hub, problems such as eccentricity, misalignment and uneven clearance are prone to occur. This leads to a decrease in gear meshing accuracy, vibration and noise during operation, reduced transmission efficiency, and long-term use will also aggravate meshing wear, affecting the service life and operational stability of the transmission system. 2. The existing connection structure of split gears is mostly rigidly fixed, lacking self-adaptive locking and anti-loosening mechanisms. Under high-speed operation and impact load conditions, the gear ring is prone to radial movement, circumferential slippage or even falling off, posing a significant safety hazard. Moreover, most split gears do not have auxiliary positioning and pre-fixing structures. During assembly, manual continuous support of the gear ring component is required, which is difficult to operate, has low assembly efficiency, and makes it difficult for a single person to quickly and independently complete the disassembly and assembly work. 3. The locking structure of traditional split gears is not linked to the drive shaft for fixing. The internal split locking components are prone to loosening and rotation, which further reduces the reliability of the overall gear structure and cannot meet the requirements of modern mechanical transmission with high precision, high load and high speed.
[0004] To address this deficiency, a modular gear that allows for easy disassembly and maintenance and can be quickly assembled and disassembled is designed. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a split gear that can be quickly disassembled and assembled, solving the problems of difficult maintenance and high replacement costs when damaged.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a split gear that can be quickly disassembled and assembled, comprising a gear assembly mounted on the surface of a rotating rod, the gear assembly comprising a hub ring, a gear ring sleeve mounted on the surface of the hub ring, and four gear ring sleeves being provided, a T-shaped inner groove being formed on the side of the inner cavity of the gear ring sleeve away from the hub ring, an annular rotating groove being formed on the inner side of the hub ring, an inner rotating shaft sleeve being rotatably mounted on the inner side of the annular rotating groove, and an L-shaped rotating opening being formed on the inner side of the inner rotating shaft sleeve, the number of L-shaped rotating openings being the same as the number of gear ring sleeves.
[0007] Preferably, the inner side of the annular rotating groove is provided with a round rotating groove, and the number of round rotating grooves is the same as that of the toothed ring sleeve. The surface of the hub ring is provided with a receiving groove that communicates with the round rotating groove. A rotating rod is provided on the inner side of the round rotating groove. An arc-shaped rotating plate is fixedly installed on the inner side of the rotating rod at the L-shaped rotating opening. A positioning stop plate that cooperates with the T-shaped inner groove is fixedly connected to one end of the rotating rod at the receiving groove.
[0008] Preferably, the top of the L-shaped rotating cavity is provided with an arc-shaped pressure part that cooperates with the arc-shaped rotating plate, and the side of the L-shaped rotating cavity away from the arc-shaped pressure part is provided with a right-angle part that cooperates with the arc-shaped rotating plate.
[0009] Preferably, the surface of the hub ring is provided with rectangular slots, and several sets of rectangular slots are provided in pairs. The front and rear parts of the inner side of the toothed ring sleeve away from the hub ring are fixedly connected with rectangular inserts, and one end of the rectangular inserts extends to the inner side of the rectangular slots.
[0010] Preferably, the toothed ring sleeve has circular grooves on both the top and bottom sides of its inner side, and a first magnetic block is fixedly connected to the inner side of the circular grooves.
[0011] Preferably, the top of the hub ring is provided with a lifting groove, and several sets of lifting grooves are provided in pairs. A cylindrical block that cooperates with the circular groove is slidably installed on the inner side of the lifting groove. A second magnetic block that cooperates with the first magnetic block is fixedly installed at the end of the cylindrical block away from the hub ring through an opening.
[0012] Preferably, the top and bottom of the hub ring are fixedly installed with a barrier seat, and a plurality of barrier seats are provided and distributed between two adjacent tooth ring sleeves.
[0013] Preferably, the top of both the hub ring and the inner rotating shaft sleeve are provided with square slots for mutual cooperation, and there are several square slots.
[0014] This invention provides a split gear that can be quickly assembled and disassembled. Compared with existing technologies, it has the following advantages: (1) This quick-release split gear achieves tool-free quick disassembly and assembly through the coordinated cooperation of the hub ring, gear ring sleeve, inner rotating shaft sleeve, rotating rod, positioning baffle plate and L-shaped rotating port, greatly simplifying the operation process and improving maintenance efficiency. During assembly, it is only necessary to fit the gear ring sleeve against the hub ring and press the arc-shaped rotating plate to make the positioning baffle plate enter the T-shaped rotating port. The inner groove allows for easy locking by rotating the inner rotating sleeve, which drives the positioning plate through the arc-shaped pressure part to engage laterally. For disassembly, rotating the inner rotating sleeve in the opposite direction pushes the arc-shaped rotating plate, resetting the positioning plate and allowing for quick removal of the gear ring sleeve. The entire process requires no bolts, nuts, pins, or other fasteners, nor any special tools. A single person can operate the entire system independently, significantly reducing gear replacement and equipment maintenance time and minimizing downtime losses. Furthermore, the guide and positioning cooperation between the rectangular insert and the rectangular slot ensures precise positioning and guidance of the gear ring sleeve during initial assembly, preventing issues such as eccentricity, misalignment, and uneven gaps. This guarantees the coaxiality and assembly accuracy of the gear ring sleeve and the hub ring, improving gear meshing accuracy, reducing vibration and noise, and optimizing transmission efficiency. This effectively solves the technical problems of cumbersome disassembly and assembly, inaccurate positioning, and high maintenance costs associated with traditional split gears.
[0015] (2) The quick-disassembly and assembly split gear combines magnetic pre-fixation, mechanical locking and transmission shaft linkage limit structure to ensure the convenience of quick disassembly and assembly of the split gear, and ensure that the gear is firmly connected and runs smoothly under high speed, high load and alternating load conditions, extending the service life of the gear, improving the safety and durability of the transmission system, and realizing the replacement of the gear ring after damage, avoiding the scrapping of the whole gear, saving material costs and usage costs, and adapting to the high-efficiency and stable transmission requirements under various working conditions.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-9 The present invention provides a technical solution: a split gear that can be quickly disassembled and assembled, including a gear assembly 1 mounted on the surface of a rotating rod 2. The gear assembly 1 includes a hub ring 101, and a gear ring sleeve 102 is mounted on the surface of the hub ring 101. Four gear ring sleeves 102 are provided. A T-shaped inner groove 103 is opened on the side of the inner cavity of the gear ring sleeve 102 away from the hub ring 101. An annular rotating groove 104 is opened on the inner side of the hub ring 101. An inner rotating shaft sleeve 105 is rotatably mounted on the inner side of the annular rotating groove 104. An L-shaped rotating opening 106 is opened on the inner side of the inner rotating shaft sleeve 105, and the number of L-shaped rotating openings 106 is the same as that of the gear ring sleeves 102.
[0020] Furthermore, a circular groove 107 is provided on the inner side of the annular groove 104, and the number of circular grooves 107 is the same as that of the gear ring sleeve 102. A receiving groove 122 connected to the circular groove 107 is provided on the surface of the hub ring 101. A rotating rod 108 is provided on the inner side of the circular groove 107. An arc-shaped rotating plate 110 is fixedly installed on the inner side of the rotating rod 108 located in the L-shaped rotating opening 106. A positioning baffle 109 that cooperates with the T-shaped inner groove 103 is fixedly connected to one end of the rotating rod 108 located in the receiving groove 122. The L-shaped opening 106 has an arc-pressing part 111 at the top of its inner cavity that works in conjunction with the arc-shaped plate 110. The L-shaped opening 106 has a right-angled part 112 on the side away from the arc-pressing part 111 that works in conjunction with the arc-shaped plate 110. The surface of the hub ring 101 has a rectangular slot 113, and several sets of rectangular slots 113 are arranged in pairs. The front and rear parts of the inner side of the toothed ring sleeve 102 away from the hub ring 101 are fixedly connected to rectangular inserts 114, and one end of the rectangular insert 114 extends into the inner side of the rectangular slot 113.
[0021] The toothed ring sleeve 102 has circular grooves 115 on both the top and bottom sides of its inner side. A first magnetic block 116 is fixedly connected to the inner side of the circular groove 115. The top of the hub ring 101 has a lifting groove 117, and several sets of lifting grooves 117 are arranged in pairs. A cylindrical block 118 that cooperates with the circular groove 115 is slidably installed on the inner side of the lifting groove 117. A second magnetic block 119 that cooperates with the first magnetic block 116 is fixedly installed at the end of the cylindrical block 118 away from the hub ring 101 through an opening.
[0022] Among them, the top and bottom of the hub ring 101 are fixedly installed with a barrier seat 120, and the barrier seat 120 is provided in several places and distributed between two adjacent toothed ring sleeves 102.
[0023] The top of the hub ring 101 and the inner rotating shaft sleeve 105 are provided with square slots 121 for mutual cooperation, and there are several square slots 121.
[0024] In use, the operator holds the hub ring 101 and then installs the toothed ring sleeve 102 onto the surface of the hub ring 101 in sequence. During installation, the rectangular insert 114 is inserted into the inner side of the rectangular slot 113 of the same group, thereby limiting and guiding the toothed ring sleeve 102 in advance. When the toothed ring sleeve 102 is completely in contact with the surface of the hub ring 101, the circular groove 115 and the lifting groove 117 are aligned, and then the first magnetic block 116 and the second magnetic block 119 generate magnetic attraction, thereby putting the toothed ring sleeve... 102 is initially fixed to the surface of the hub ring 101. At this point, the operator can proceed with the next step without holding the gear ring sleeve 102 by hand. Then, the operator presses several arc-shaped rotating plates 110 sequentially on the inside of the hub ring 101 with their fingers, causing the rotating rod 108 to push the vertically positioned positioning stop plate 109 into the inside of the T-shaped inner groove 103. At this point, the arc-shaped rotating plates 110 are completely inside the L-shaped rotating openings 106 and 106. Then, the operator rotates the inner rotating bushing 105 with their fingers. This causes the arc-shaped pressure section 111 to compress the arc-shaped rotating plate 110 and rotate it. The arc-shaped rotating plate 110, driven by the rotating rod 108, drives the positioning stop plate 109 to rotate synchronously to a lateral state. At this time, after the positioning stop plate 109 rotates to the lateral state, it engages with the T-shaped inner groove 103. At this time, the gear ring sleeve 102 is completely fixed to the surface of the hub ring 101. Simultaneously, the hub ring 101 coincides with the square groove 121 of the inner rotating shaft sleeve 105, and then is fixed with the rotating rod 2. After the rotating rod 2 is inserted into the wheel... When the hub ring 101 and the square slot 121 are moved inside, the inner rotating bushing 105 is fixed at the same time, and then it can be used. When the gear ring sleeve 102 is damaged and needs to be disassembled, the gear assembly 1 is removed from the surface of the rotating rod 2, and then the inner rotating bushing 105 is rotated in the opposite direction, so that the right angle part 112 presses the arc rotating plate 110 part, thereby causing the arc rotating plate 110 to drive the positioning stop plate 109 to rotate to a vertical state, so that the gear ring sleeve 102 can be easily removed and replaced.
[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
