Description

Technical Field

[0001] This utility model relates to the field of sintering furnaces, specifically a transmission structure for a roller sintering furnace. Background Technology

[0002] The sintering furnace contains a material transport device, with shafts and rollers being key components. The shaft is typically the drive component, rotated by a power source such as a motor. The rollers contact the shaft and carry the material to be sintered or material-carrying devices (such as conveyor belts or trays). When the shaft rotates, friction exists between the shaft and the rollers, causing the rollers to rotate along with the shaft, thus moving the connected material or material-carrying device and achieving material transport within the sintering furnace. This transmission method ensures that the material moves smoothly within the sintering furnace at a certain speed and direction, sequentially passing through different zones such as the preheating zone, sintering zone, and cooling zone, thereby completing the entire sintering process. Friction-driven transmission can also precisely control the material transport speed by adjusting parameters such as the shaft speed and roller diameter to meet the requirements of different sintering processes.

[0003] However, through our long-term observation, we have found that during the sintering process, the transmission is carried out by the friction between the shaft and the roller; during operation, it is easy to jam and stop rotating, which leads to the bending and deformation of the shaft at high temperature, resulting in defective products or even scrap. Utility Model Content

[0004] The purpose of this invention is to provide a transmission structure for a roller sintering furnace to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a transmission structure for a roller sintering furnace is provided, comprising a master-slave spring sleeve, a driven shaft mounted on one side of the master-slave spring sleeve, a sintering shaft mounted on the other side of the master-slave spring sleeve, a transmission gear fixedly mounted on the outer circumference of the driven shaft, a driving gear provided on one side of the transmission gear, a drive shaft fixedly mounted on the inner circumference of the drive gear, a bearing seat provided at the end of the drive shaft, and the end of the drive shaft movably mounted on the side wall of the sintering furnace body via the bearing seat; a female shaft sleeve is provided inside the master-slave spring sleeve, a male shaft rod is provided inside the female shaft sleeve, and a spring is provided inside the female shaft sleeve.

[0006] Preferably, the sizes of the driving gear and the transmission gear are matched, and the driving gear and the transmission gear are meshed together; the drive shaft drives the driven shaft to rotate through the driving gear and the transmission gear.

[0007] Preferably, the thickness of the driving gear is three times the thickness of the transmission gear. The transmission gear is connected to the sintering shaft through a driven shaft and a mother-daughter spring sleeve. The sintering shaft passes through the side wall of the sintering furnace body and extends inside the sintering furnace body.

[0008] Preferably, the female and male spring sleeve includes a female bushing, a transmission groove, a transmission seat, a male shaft, a spring, a fixed seat A, and a fixed seat B. The end of the female bushing is connected to the sintering shaft, and the male shaft is movably inserted inside the female bushing.

[0009] Preferably, a sintered shaft is fixedly installed at the end of the sub-shaft, eight sets of transmission seats are evenly arranged on the outer circumference of the sub-shaft, and eight sets of transmission grooves are evenly opened on the inner circumference of the mother shaft sleeve, with the dimensions of the transmission grooves and transmission seats being compatible.

[0010] Preferably, the eight sets of transmission seats are respectively inserted into the interior of the eight sets of transmission slots. The cross-sections of the transmission slots and transmission seats are rectangular. The driven shaft and the sintering shaft are connected by a female shaft sleeve and a male shaft rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model changes the transmission method between the drive shaft and the sintering shaft from friction transmission to gear transmission. The drive shaft drives the transmission gear meshing with it to rotate through the driving gear. When the transmission gear rotates, it drives the sintering shaft to rotate through the driven shaft and the male and female spring sleeves. This solves the problem of jamming and stopping during high-temperature sintering, improves efficiency and reduces risks; and avoids the situation where the shaft bends and deforms at high temperatures, resulting in defective products or even scrap.

[0014] 2. This utility model uses a male and female spring sleeve at the connection between the passive shaft and the sintering shaft. The male and female spring sleeve contains a spring. The part of the sintering shaft that extends into the sintering furnace body will increase its axial length under high temperature. The elasticity of the spring is used to automatically adjust the sintering shaft from room temperature to high temperature and back to room temperature, causing the shaft to stretch. This greatly improves efficiency and reduces the risk of shaft deformation and bending caused by high temperature sintering. Attached Figure Description

Detailed Implementation

[0022] Please see Figure 1-6 This utility model provides a transmission structure for a roller sintering furnace, including a master spring sleeve 6, a driven shaft 5 installed on one side of the master spring sleeve 6, a sintering shaft 51 installed on the other side of the master spring sleeve 6, a transmission gear 21 fixedly installed on the outer circumference of the driven shaft 5, a driving gear 2 provided on one side of the transmission gear 21, a drive shaft 1 fixedly installed on the inner circumference of the drive gear 2, a bearing seat 3 provided at the end of the drive shaft 1, and the end of the drive shaft 1 movably mounted on the side wall of the sintering furnace body 4 through the bearing seat 3; a female shaft sleeve 61 is provided inside the master spring sleeve 6, a male shaft rod 64 is provided inside the female shaft sleeve 61, and a spring 65 is provided inside the female shaft sleeve 61.

[0023] Working Principle: In actual use, the transmission method between the drive shaft 1 and the sintering shaft 51 is changed from friction transmission to gear transmission. Specifically, the drive shaft 1 is fixed to the output shaft of the reducer via a coupling. The reducer drives the drive shaft 1 to rotate. The drive shaft 1 drives the transmission gear 21, which meshes with it, to rotate via the drive gear 2. When the transmission gear 21 rotates, it drives the sintering shaft 51 to rotate via the driven shaft 5 and the female and male spring sleeves 6. This solves the problem of jamming and stopping during high-temperature sintering, improves efficiency and reduces risk. It also avoids the shaft bending and deformation at high temperatures, which could lead to defective or even scrapped products. The driven shaft 5 drives the sintering shaft 51 to rotate as follows: the driven shaft 5 and the sintering shaft 51 are connected by the female shaft sleeve 61 and the male shaft rod 64. The female shaft sleeve 61 and the male shaft rod 64 are connected by eight sets of transmission seats 63, which are respectively inserted into eight sets of transmission slots 62, to complete the torque transmission between the driven shaft 5 and the sintering shaft 51.

[0024] A rubber pad can be installed between the transmission seat 63 and the transmission groove 62 for connection. The rubber pad is not shown in the figure. First, it can change the rigid connection between the transmission seat 63 and the transmission groove 62 into an elastic connection, reducing the friction and noise between the transmission seat 63 and the transmission groove 62. At the same time, when the transmission seat 63 expands due to heat, it will squeeze the rubber pad to prevent the transmission groove 62 from being squeezed and deformed.

[0025] A male and female spring sleeve 6 is provided at the connection position between the passive shaft 5 and the sintering shaft 51; a spring 65 is provided inside the male and female spring sleeve 6. The part of the sintering shaft 51 that extends into the sintering furnace body 4 will increase its axial length under the action of high temperature; by utilizing the extensibility of the spring 65, the sintering shaft 51 is automatically adjusted from room temperature to high temperature and back to room temperature, causing the shaft to stretch and change variable; this greatly improves efficiency and reduces the risk of shaft deformation and bending caused by high temperature sintering.

[0026] In a preferred embodiment, the sizes of the drive gear 2 and the transmission gear 21 are matched, and the drive gear 2 and the transmission gear 21 are meshed and connected; the drive shaft 1 drives the driven shaft 5 to rotate through the drive gear 2 and the transmission gear 21.

[0027] In a preferred embodiment, the thickness of the driving gear 2 is three times the thickness of the transmission gear 21. The transmission gear 21 is connected to the sintering shaft 51 through the driven shaft 5 and the mother-daughter spring sleeve 6. The sintering shaft 51 passes through the side wall of the sintering furnace body 4 and extends inside the sintering furnace body 4.

[0028] In a preferred embodiment, the male and female spring sleeve 6 includes a female bushing 61, a transmission groove 62, a transmission seat 63, a male shaft 64, a spring 65, a fixed seat A66, and a fixed seat B661.

The cross-sections of the transmission slots 62 and the transmission seats 63 are both rectangular. The passive shaft 5 and the sintering shaft 51 are connected by a female shaft sleeve 61 and a male shaft rod 64.
