Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a transmission mechanism. Background Technology

[0002] In industrial production, roller drive mechanisms are widely used in material conveying and assembly line transport. However, traditional roller assemblies have significant design limitations, particularly in meeting the demands of modern high-paced production, especially in the precise conveying of small parts and ease of maintenance. Specific problems include:

[0003] 1. Difficulty in maintenance: When a single roller needs to be replaced due to wear, deformation or blockage, multiple adjacent rollers or even the entire transmission mechanism need to be disassembled, which takes up to several hours and seriously slows down the production progress;

[0004] 2. High cost: Partial damage requires replacing the entire roller assembly, rather than just the damaged part, resulting in material waste;

[0005] 3. Poor flexibility: It is impossible to quickly adjust the roller type (such as friction roller, gear roller) according to the size of the conveyed material, requiring the machine to be stopped and the entire set of equipment to be reassembled. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a transmission mechanism with a quick-release structure for the roller assembly, which facilitates replacement and maintenance.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a transmission mechanism, including several horizontally and parallelly arranged roller assemblies, mounting plates at both ends of the roller assemblies, and a drive assembly for driving the roller assemblies. The roller assembly includes a hollow power roller, a mandrel passing through the power roller, and a fixing ring sleeved on the mandrel and located at the end of the power roller. The two ends of the mandrel are respectively pivotally connected to the mounting plates on both sides through flange bearings. The fixing ring is located between the mounting plate and the power roller. A spring is provided between the fixing ring and the end of the power roller. One end of the fixing ring abuts against the spring, and the other end of the fixing ring abuts against the mounting plate. One end of the mandrel is connected to a first gear. A second gear is provided between the first gears of adjacent roller assemblies. The second gear is pivotally connected to the mounting plate, and the first gear meshes with the second gear. The principle of this invention is as follows: When the roller assembly is working, the power source drives the first second gear through the drive component. The second gear drives the two first gears meshing with it. The first gears then transmit power through the second gears between them, thereby driving all roller assemblies to rotate in the same direction. When disassembling the roller assembly, loosen the locking bolts on the fixing rings at both ends and pull the shaft core out from its driving end. After replacing or repairing the parts, reinsert the shaft core into the power roller and lock the fixing rings at both ends.

[0008] As an improvement, a connecting rod is provided between the two mounting plates, and the connecting rod is located above the roller assembly.

[0009] As an improvement, the fixing ring is provided with a locking screw hole and a locking bolt that mates with the locking screw hole.

[0010] As an improvement, the drive assembly includes a drive shaft, a third gear at one end of the drive shaft and a fourth gear at the other end of the drive shaft, the third gear meshing with one of the second gears, one end of the drive shaft being pivotally connected to a mounting plate and the other end being pivotally connected to an inlet side plate.

[0011] The beneficial effects of this utility model compared with the prior art are:

[0012] The power roller and shaft are designed to be detachable. When disassembling the roller assembly, loosen the locking bolts on the retaining rings at both ends and pull the shaft out from the drive end. After replacing or repairing the parts, reinsert the shaft into the power roller and lock the retaining rings at both ends. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 4As shown, a transmission mechanism includes several horizontally and parallelly arranged roller assemblies 7, mounting plates 3 at both ends of the roller assemblies 7, and a drive assembly for driving the roller assemblies 7. A connecting rod 6 is provided between the two mounting plates 3, and the connecting rod 6 is located above the roller assembly 7. The connecting rod 6 is used to ensure the installation accuracy of the two mounting plates 3. The roller assembly 7 includes a hollow power roller 72, a mandrel 71 passing through the power roller 72, and a retaining ring 73 sleeved on the mandrel 71 and located at the end of the power roller 72. The mandrel 71 is a D-shaped shaft, and both ends of the power roller 72 are provided with D-shaped holes similar in shape to the mandrel. After the mandrel passes through the power roller 72, it can drive the roller to rotate together. Both ends of the mandrel 71 are pivotally connected to the mounting plates 3 on both sides via flange bearings. The retaining ring 73 is located between the mounting plate 3 and the power roller 72. A spring 74 is provided between the retaining ring 73 and the end of the power roller 72. One end of the retaining ring 73 abuts against the spring 74, and the other end of the retaining ring 73 abuts against the mounting plate 3. The mandrel 71 is fixed to the mounting plates 3 on both sides by flange bearings at both ends. The spring 74 is compressed to generate preload force to compensate for installation tolerance. One end of the mandrel 71 extends out of the mounting plate 3 and is connected to the first gear 1. A second gear 2 is provided between the first gear 1 of adjacent roller assemblies 7. The second gear 2 is pivotally connected to the outside of the mounting plate 3. The first gear 1 and the second gear 2 mesh. Power is transmitted between adjacent first gear 1 through the second gear 2, so that each roller assembly 7 can rotate synchronously in the same direction. The fixing ring 73 is provided with locking screw holes and locking bolts that cooperate with the locking screw holes. The locking bolts can fix the fixing ring 73 to the shaft core. The fixing rings 73 at both ends can limit the axial movement of the shaft core. The drive assembly includes a drive shaft 9, a third gear 88 located at one end of the drive shaft 9, and a fourth gear 4 located at the other end of the drive shaft 9. The third gear 8 meshes with one of the second gears 2. One end of the drive shaft 9 is pivotally connected to the mounting plate 3, and the other end is pivotally connected to the inlet side plate 5. An external power source drives the fourth gear 4, which in turn drives the third gear 8 via the drive shaft 9. The third gear 8 then drives the roller assembly 7.

[0019] The principle of this invention is as follows: When the roller assembly 7 is working, the power source drives the first second gear 2 through the drive assembly. The second gear 2 drives the two first gears 1 that mesh with it. The first gears 1 then transmit power through the second gears 2 between them, thereby driving all roller assemblies 7 to rotate in the same direction. When disassembling the roller assembly 7, loosen the locking bolts on the fixing rings 73 at both ends and pull the shaft core out from its driving end. After replacing or repairing the parts, reinsert the shaft core into the power roller 72 and lock the fixing rings 73 at both ends.
