[0025] Example

[0026] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a wear-resistant structure for a mechanical transmission component, including:

[0027] The support component 100 includes a bracket 101, a support plate 102 fixedly connected to the side wall of the bracket 101, a fixing plate 103 fixedly connected to the upper end of the support plate 102, and a support member 104 fixedly connected to the side wall of the fixing plate 103. The end of the support member 104 is bolted to the side wall of the support plate 102.

[0028] The transmission component 200 includes a bearing housing 201 fixedly connected to the side wall of the support plate 102, a sleeve 202 adapted to be installed in the center of the bearing housing 201, a bushing 203 fixedly connected to the middle of the sleeve 202, and a transmission shaft 204 fixedly connected to the inner wall of the bushing 203. The transmission shaft 204 runs inside the fixed plate 103, and the side wall of the bearing housing 201 is connected to the fixed plate 103 by bolts.

[0029] The support component 100, serving as the basic framework of the entire structure, consists of a bracket 101, a support plate 102, a fixing plate 103, and a support member 104, providing a stable platform for the installation of subsequent components. The fixing plate 103 is vertically fixed to the upper end of the support plate 102, further enhancing the structural stability. One end of the support member 104 is connected to the side wall of the fixing plate 103, and the other end is bolted to the side wall of the support plate 102, effectively distributing the load pressure from the transmission components and ensuring the stability of the entire support system under complex working conditions, avoiding additional wear caused by shaking. The bearing housing 201 is fixed to the side wall of the support plate 102, and the sleeve 202 fitted at its center provides precise positioning and support space for the bushing 203. The inner wall of the bushing 203 tightly fixes the drive shaft 204, which runs inside the fixed plate 103. The side wall of the bearing seat 201 is connected to the fixed plate 103 by bolts, which not only ensures the coaxiality of the drive shaft 204 when it rotates, but also restricts its radial and axial displacement, reducing wear caused by misalignment.

[0030] Specifically, a coupling 205 is installed at the end of the drive shaft 204, and the drive shaft 204 is symmetrically installed at both ends of the coupling 205.

[0031] The coupling 205 installed at the end of the drive shaft 204 enables the segmented connection of the drive shaft 204, which facilitates installation and maintenance, and can also absorb a certain amount of vibration and offset.

[0032] Furthermore, the transmission component 200 also includes a secondary sprocket 206 fixedly connected to the side wall of the transmission shaft 204, and a chain 207 adapted to be installed on the side wall of the secondary sprocket 206. The two sets of transmission shafts 204 are connected by transmission through the secondary sprocket 206 and the chain 207. The support plate 102 has a relief groove in the middle for use with the chain 207, and the chain 207 extends to the bottom of the support plate 102.

[0033] The two sets of drive shafts 204 are connected by a secondary sprocket 206 fixed to their sidewalls and a chain 207 adapted to be installed on the sidewalls of the secondary sprocket 206. This sprocket and chain drive method features accurate transmission ratio and high transmission efficiency, and can stably transmit power to assist the operation of the drive shafts 204. The clearance groove in the middle of the support plate 102 provides room for the chain 207 to move, avoiding interference and wear between the chain and the support plate 102 during operation. Furthermore, the chain 207 extends below the support plate 102, optimizing the overall layout.

[0034] It should be noted that the transmission component 200 also includes a support plate 208 fixedly connected to the bottom of the support plate 102, a mounting plate 209 fixedly connected to the side wall of the support plate 208, a motor 210 fixedly connected to the side wall of the mounting plate 209, and a main sprocket 211 adapted to be installed at the output end of the motor 210. The main sprocket 211 is connected to the secondary sprocket 206 via a chain 207.

[0035] The support plate 208 is fixed to the bottom of the support plate 102, and the mounting plate 209, motor 210 and main sprocket 211 mounted on it constitute the power source. The main sprocket 211 at the output end of the motor 210 is connected to the secondary sprocket 206 through the chain 207, which transmits the rotational power of the motor to the drive shaft 204.

[0036] Preferably, the transmission component 200 further includes an auxiliary shaft 212 rotatably mounted on the side wall of the fixed plate 103, and a roller 213 adapted to be mounted on the end of the auxiliary shaft 212, the roller 213 being disposed above the transmission shaft 204.

[0037] The auxiliary shaft 212, which is rotatably mounted on the side wall of the fixed plate 103, and the roller 213 at its end are positioned above the transmission shaft 204, playing a supporting and guiding role, reducing the sagging and shaking of the transmission shaft 204 during operation, thereby reducing wear.

[0038] Preferably, the transmission component 200 further includes a connecting rod 214 fixedly connected to the side wall of the fixed plate 103, and a baffle 215 fixedly connected to the end of the connecting rod 214, and a pulley 216 disposed inside the baffle 215 is installed at the end of the auxiliary shaft 212.

[0039] The connecting rod 214 and the end baffle 215 fixed to the side wall of the fixed plate 103, together with the pulley 216 at the end of the auxiliary shaft 212, further restrict the range of motion of the auxiliary shaft 212, ensure its stable operation, and provide continuous and effective auxiliary support for the transmission shaft 204.

[0040] During operation, the motor 210 starts, and the main sprocket 211 at its output end begins to rotate, transmitting power to the secondary sprocket 206 via the chain 207. The secondary sprocket 206 drives the drive shaft 204, which is fixedly connected to it, to rotate. Due to the connection of the coupling 205, the two sets of drive shafts 204 rotate synchronously, realizing the mechanical transmission function. During the rotation of the drive shaft 204, the upper roller 213 closely fits the drive shaft 204, providing upward support and preventing the drive shaft 204 from sagging due to its own weight or load, ensuring its smooth operation. At the same time, the pulley 216, under the restriction of the baffle 215, ensures the stable rotation of the auxiliary shaft 212, continuously providing power support to the roller 213. Throughout the transmission process, the support component 100, with its robust structure, bears and disperses various forces from the transmission component 200, maintaining the stable operation of the system. The precise cooperation and reasonable layout between the components effectively reduce mutual friction and wear.

[0041] In summary, the precise positioning and support of the transmission shaft 204 by the bearing housing 201 and bushing 203, along with the auxiliary support of the roller 213, reduces the offset and wobbling of the transmission shaft 204 during rotation, lowers friction and wear between the shaft and bearings, and between the shaft and other components, and extends the service life of the transmission components. The sprocket and chain drive, combined with a reasonable clearance groove design, avoids interference wear between the chain and other components, ensuring the reliability of the transmission system. The reinforced structure of the support component 100 and the tight fit between the various components of the transmission component 200 enhance the stability of the entire structure. During operation, it can effectively resist external vibrations and impacts, ensuring smooth operation of the transmission system, improving the accuracy and reliability of mechanical transmission, and is suitable for working conditions with high requirements for transmission stability. The use of the coupling 205 makes the installation and disassembly of the transmission shaft 204 more convenient, allowing for quick replacement and repair when a component malfunctions. Simultaneously, the bolted connections of the components facilitate daily inspection and maintenance, reducing equipment maintenance costs and downtime.
