Description

08bs double-speed chain large head small tail drive mechanism Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, and in particular to the 08bs double-speed chain large head small tail drive mechanism. Background Technology

[0002] Double-speed chain conveyors, as core transmission equipment in automated production lines, are widely used in assembly, testing, and warehousing processes in manufacturing industries such as electronics, home appliances, and automotive parts. They achieve efficient and continuous material transport through the speed-increasing characteristics of the double-speed chain, and can achieve precise material positioning and accumulation through stoppers and guiding mechanisms. The double-speed chain drive mechanism, as the power core of the conveyor, directly affects the stability, reliability, and adaptability of material transport, and is a key component determining the efficiency of the production line.

[0003] However, existing tensioning mechanisms are mostly pure spring automatic tensioning or manual screw adjustment, which cannot dynamically lock the tension according to the load. Automatic tensioning lacks a rigid locking structure after tensioning, and the chain is prone to tension fluctuations in high-speed operation or vibration environment, causing tooth skipping or even breakage. Manual adjustment requires stopping the machine, which is time-consuming and the accuracy depends on the operator's experience. Uneven tension can easily aggravate sprocket wear. Traditional tail bearings are mostly rigidly fixed to the tail plate by nuts and bolts. When replacing them, the entire tail structure and chain must be disassembled, which seriously affects the continuity of production, has poor compatibility, and cannot be quickly replaced.

[0029] The following describes the 08bs double-speed chain large-head-small-tail drive mechanism of this utility model with reference to the accompanying drawings. Example

[0030] As shown in Figures 1 to 9, a 08bs double-speed chain drive mechanism with a large head and small tail includes two symmetrically arranged head assemblies 100 and tail assemblies 200. The head assemblies 100 and tail assemblies 200 are connected by a profile 300. A 08bs double-speed chain 310 is provided in the profile 300. A drive device 101 for driving a first drive shaft 140 is provided on the side of the head assembly 100. A connector 102 is provided between the head assemblies 100. The two symmetrically arranged head assemblies 100 and tail assemblies 200 are connected by the profile 300 and the 08bs double-speed chain 310. The connector 102 between the head assemblies 100 and the first drive shaft 140 ensure power transmission and stable operation.

[0031] The head assembly 100 includes a head housing 110, a first gear 120, a first bearing 130, a first drive shaft 140, a guide wheel 150, and a tensioning assembly 160. The head housing 110 has a bearing seat 111 inside, and the first bearing 130 is mounted on the bearing seat 111. The first bearing 130 is fixedly connected to the first gear 120. The first gear 120 has a synchronous pulley 121 on it, and the first gear 120 is connected to the first drive shaft 140. The head assemblies 100 are connected to each other through the first drive shaft 140. The guide wheel 150 is mounted on the upper end of the head housing 110, and the guide wheel 150 is connected to the synchronous pulley 121 through a transmission belt. Two sets of head assembly 100 are connected by a first drive shaft 140. The drive device 101 drives the first drive shaft 140. The first gear 120, the first bearing 130 and the synchronous pulley 121 in the two sets of head assembly 100 cooperate to drive the guide pulley 150 through the transmission belt, providing power for the chain to run and ensuring the synchronicity of the conveying process.

[0032] The tensioning assembly 160 is located inside the head housing 110. A fixed shaft 161 is mounted on the tensioning assembly 160, passing through the head housing 110. A handle 162 is located at the end of the fixed shaft 161. The fixed shaft 161 and handle 162 are mounted on the tensioning assembly 160 to lock it after the tension of the 08bs double-speed chain 310 is adjusted, preventing fluctuations in the tensioning assembly 160 during operation and ensuring uneven tension.

[0033] The tail assembly 200 includes a tail housing 210, a second gear 220, and a second bearing assembly 230. The tail housing 210 has a first notch 211 on each side, and a second bearing assembly 230 is provided in each first notch 211. The second gear 220 is disposed between the second bearing assemblies 230 and is fixedly connected to the second bearing assemblies 230.

[0034] Two sets of machine head assemblies 100 are symmetrically placed at the front end of the production line. A mounting bracket 112 is provided on the machine head housing 110, and the profile 300 is fixed to the mounting bracket 112 with bolts. A first top cover 113 is provided on the top of the machine head housing 110. The first top cover 113 prevents foreign objects from falling into the machine head, protecting internal components and extending the equipment's service life. A fixing member 114 is provided on the machine head housing 110, and a first support member 115 for supporting the 08bs double-speed chain 310 is provided on the fixing member 114. The first support member 115 is fixedly connected to the machine head housing 110 with bolts. The fixing component 114 provides an installation platform for the first support component 115 and the tensioning assembly 160. The fixing design with the head housing 110 improves stability. The first support component 115 on the fixing component 114 is fixed to the head housing 110 by bolts, which can effectively support the 08bs double speed chain 310, reduce the sagging and shaking of the chain due to its own weight, ensure the smooth operation of the chain, and thus improve the stability and reliability of material conveying on the 08bs double speed chain 310.

[0035] The first bearing 130 and the synchronous pulley 121 are respectively fixedly connected to both sides of the first gear 120. The first drive shaft 140 is provided with a first pin 141, and the first gear 120 is provided with a first slot 122 that matches the first pin 141. The first bearing 130 in the bearing housing 111 supports the rotation of the first gear 120, reduces frictional resistance, and ensures the stability of the drive shaft when rotating at high speed. The synchronous pulley 121 fixed on the first gear 120 is connected to the guide wheel 150 through a transmission belt, which synchronously transmits the driving force of the first gear 120 to the guide wheel 150, so as to achieve consistent speed and ensure the synchronicity and stability of material conveying.

[0036] The tensioning assembly 160 includes a fixing post 163, a tensioning block 164, and a spring 165. The fixing post 163 is mounted on the fixing member 114. The fixing post 163 is vertically fixed to the fixing member 114 of the head housing 110, serving as a guide reference for the tensioning block 164 and ensuring that the tensioning block 164 slides accurately in the vertical direction. The tensioning block 164 is located below the fixing post 163 and has a connection port 166. The tensioning block 164 is fitted under the fixing post 163 through the connection port 166, with its bottom surface contacting the chain. The spring 165 surrounds the fixing post 163 and extends into the connection port 166 of the tensioning block 164. Spring 165 surrounds fixed post 163 and extends into tension block 164 connection port 166, providing continuous tension force through elastic deformation; the depth of connection port 166 matches the compression stroke of spring 165, ensuring that the elastic force of spring 165 is evenly transmitted to the chain, automatically compensating for the elongation caused by chain wear.

[0037] The tension block 164 has guide pins 167 on both sides, and the head housing 110 has symmetrical guide grooves 116 that slide with the guide pins 167. The guide pins 167 on both sides of the tension block 164 are inserted into the symmetrical guide grooves 116 on the head housing 110 to form a precision sliding pair, which restricts the lateral displacement of the tension block 164 and ensures that the tension force acts perpendicularly on the chain, avoiding one-sided wear of the chain due to tilting. The guide groove 116 on one side of the head housing 110 has a groove 117, and the fixed shaft 161 passes through the groove 117. The end of the fixed shaft 161 is threaded. The end thread engages with the handle 162 to lock the tensioning assembly 160. When adjusting the tension, the tensioning block 164 drives the fixed shaft 161 to slide up and down along the groove 117 and guide groove 116. After reaching the desired position, the tensioning block 164 is locked in place by the thread, thus preventing the spring 165 from drifting due to long-term stress.

[0038] A fixing pin 170 is provided inside the head housing 110 adjacent to the mounting bracket, and a first guide block 171 is provided on the fixing pin 170. The first guide block 171 is sleeved on the fixing pin 170, and its inner side has an arc-shaped guide surface, which forms a rigid constraint on the lateral displacement of the 08bs double speed chain 310, avoiding friction between the chain and the inner wall of the head housing 110. A guide member 172 is provided at the bottom of the head housing 110. The guide member 172 is located below the first gear 120, reducing the amount of chain sag when unloaded, and providing a certain support for the chain when adjusting the tension of the 08bs double speed chain 310.

[0039] Furthermore, the surface of the first guide block 171 is provided with a V-shaped guide groove, which cooperates with the flange of the chain main wheel 311 to provide longitudinal support.

[0040] The tail housing 210 has a second top cover 212 on its top and a mounting groove 213 on its top. A second support member 214 is located within the mounting groove 213. The width of the second support member 214 matches the mounting groove 213, supporting the unloaded section of the 08bs double-speed chain 310 and reducing chain sag at the tail end. The bottom of the tail housing 210 has an insertion hole 215, in which a connecting pin 216 for connection with the profile 300 is located. During installation, the connecting pin 216 is inserted into the insertion hole 215 at the end of the profile 300, achieving a rigid connection between the tail assembly 200 and the profile 300. Compared to traditional direct bolt connections, this provides higher installation efficiency and facilitates later disassembly and maintenance. A second guide block 217 is located inside the tail housing 210, fixed to the inner wall of the tail housing 210 to prevent the chain at the tail end from deviating.

[0041] Furthermore, the surface of the second guide block 217 is provided with the same guide groove as the first guide block 171, forming a bidirectional constraint with the first guide block 171 of the machine head.

[0042] The second bearing assembly 230 is provided with a second pin 231, and the first notch 211 of the tail housing 210 is provided with a second slot 218 that matches the second pin 231. The second pin 231 on the second bearing assembly 230 and the second slot 218 of the first notch 211 of the tail housing 210 form a precise insertion and removal fit, which can quickly install or remove the bearing assembly, solving the problem of time-consuming and laborious traditional bolt fixing methods. The second bearing assembly 230 is provided with a dust cover 232, which is fastened to the outside of the second bearing assembly 230 to effectively prevent dust and oil from entering the bearing.

[0043] Furthermore, as shown in Figure 10, the second bearing assembly 230 can be replaced with a second tensioning assembly. The second tensioning assembly has a transverse guide groove, within which a limiting shaft is installed. The limiting shaft passes through the second gear 220 and connects to the second tensioning assembly at the other end. Threaded holes are provided on the limiting shaft and the second tensioning assembly, and limiting screws are installed in these threaded holes. The limiting screws are perpendicular to the limiting shaft. When the limiting shaft stops moving, the limiting screws are tightened. Through the transversely adjustable limiting shaft and limiting screws, precise adjustment of the position of the second gear 220 is achieved, thereby dynamically compensating for the elongation of the chain due to wear, thus assisting in adjusting the chain tension.

[0044] The 08bs double-speed chain 310 includes a main wheel 311, an auxiliary wheel 312, a pad 313, and a pin 314. Pads 313 are located on both sides of the main wheel 311, and the main wheel 311 and pads 313 are connected by the pin 314. The auxiliary wheels 312 are located at both ends of the outer side of the pin 314. The first gear 120 and the second gear 220 have double rows of teeth, which are inserted between the auxiliary wheels 312. Because the auxiliary wheels 312 are distributed on both sides of the chain, the double-row tooth design of the gears allows the gears to mesh with the auxiliary wheels 312 on both sides of the chain simultaneously, increasing the contact area between the gears and the chain, providing double-sided constraint and support, and enabling more efficient and smooth power transmission from the gears to the chain.

[0045] In this embodiment, the first gear 120 in the head assembly 100 is connected to the first drive shaft 140 via the first pin 141. The first drive shaft 140 transmits driving force to both head assemblies 100 simultaneously, and also transmits it synchronously to the guide wheel 150 via the synchronous pulley 121. The first drive shaft 140 ensures consistent power on both heads, solving the problems of transmission gap and uneven power in the prior art. The tensioning assembly 160 is locked through the cooperation between the handle 162, the fixed shaft 161, and the tensioning assembly 160, avoiding uneven tension. The modular pin-type second bearing assembly 230 of the tail assembly 200 improves maintenance efficiency and adapts to the rapid maintenance needs of automated production lines. The 08bs double-speed chain 310, in conjunction with the first gear 120 and the second gear 220 with double rows of teeth, makes the chain transport more efficient and stable.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Those skilled in the art may find other optimizations and additional functions in this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
