Description

Technical Field

[0001] This utility model relates to the technical field of grease processing equipment, and in particular to a gear mounting mechanism and a horizontal rotary device. Background Technology

[0002] Oil pretreatment refers to a series of processes performed on oilseeds before oil extraction, including cleaning, peeling, descaling, crushing, softening, rolling, puffing, wet heat treatment, and drying. The purpose is to remove impurities and process the oilseeds into materials with certain structural properties to meet the requirements of different oil extraction processes.

[0003] In commonly used oil pretreatment processes, horizontal steaming and frying pans are typically selected. A horizontal steaming and frying pan consists of a rotating cylinder with gears mounted on its outer casing. The rotation of the gears drives the rotation of the cylinder, thus processing the materials. The gears and the rotating cylinder are generally connected by flange bolts; that is, a flange is welded to the outer wall of the rotating cylinder, then connected to the gear flange, and secured with bolts.

[0004] However, during long-term operation, the bolt preload of a horizontal steaming and frying pan may gradually decrease due to vibration, thermal expansion, or material creep, causing relative displacement of the flange surface, resulting in loosening or breakage of the bolts, which seriously affects the stable operation and use of the horizontal steaming and frying pan. Utility Model Content

[0005] In view of this, the present invention proposes a gear mounting mechanism and a horizontal rotary device, which can solve the problems of easy loosening or breakage of the connecting bolts between the gear and the cylinder and low reliability.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a gear mounting mechanism, including:

[0008] A connecting pad is assembled between the rotating cylinder and the large gear, and the connecting pad is disposed on the rotating cylinder;

[0009] Two fixing members are respectively disposed on both axial sides of the large gear and located on the connecting pad. Each fixing member has a circumferential connecting member on both circumferential sides of the large gear, and the circumferential connecting member is also connected to the rotating cylinder.

[0010] The first mounting component connects the large gear and the two fixing members.

[0011] Based on the above technical solutions, preferably, a reinforcing rib is provided between the fixing member and the connecting pad.

[0012] More preferably, there are two reinforcing ribs, which are respectively connected to both ends of the fixing member, and the first mounting component is connected to the middle of the fixing member.

[0013] Based on the above technical solutions, preferably, the first mounting component includes a first connector, and the corresponding positions of the fixing component and the large gear are provided with first connecting holes, the connecting ends of the first connector are sequentially passed through each of the first connecting holes, and the connecting ends of the first connector are connected to first fasteners.

[0014] More preferably, the connecting end of the first connector is also connected to a second fastener, the second fastener being located outside the first fastener.

[0015] More preferably, each of the two fasteners has a first washer on its opposite side, and the two first washers respectively cooperate with the first connector and the first fastener.

[0016] Based on the above technical solutions, preferably, the connecting pad is provided with an adjustment component on the side facing the large gear, and the adjustment component is used to adjust the gap between the outer diameter of the rotating cylinder and the inner diameter of the large gear.

[0017] More preferably, it also includes a second mounting component, which is detachably connected to the adjusting component and the connecting pad.

[0018] More preferably, the adjusting component includes an adjusting pad disposed on the connecting pad, and an adjusting shim is disposed between the adjusting pad and the connecting pad.

[0019] This utility model also provides a horizontal rotary device, including a rotary cylinder, a transmission device, and the gear mounting mechanism described above. The transmission device includes a small gear that is rotatably disposed and a large gear that meshes with the small gear. The gear mounting mechanism connects the large gear and the rotary cylinder.

[0020] The gear mounting mechanism and horizontal rotary device of this utility model have the following advantages over the prior art:

[0021] (1) By setting the fastener on the connecting pad, the large gear and the fastener are connected by the first mounting component, and the position of the large gear in the axial direction is limited and fixed; by setting the circumferential connecting component, the position of the large gear in the circumferential direction is limited and fixed, so as to ensure the reliability of the connection between the large gear and the rotary cylinder. During the operation of the rotary cylinder, the dynamic load can be reduced, the risk of fatigue fracture can be reduced, the possibility of failure of the connection between the rotary cylinder and the large gear can be reduced, and the safety of the device can be ensured.

[0022] (2) Adjust the gap between the outer diameter of the rotary cylinder and the inner diameter of the large gear by adjusting the components, so that the gap between the outer diameter of the rotary cylinder and the inner diameter of the large gear can reach the optimal working gap range. When the equipment is running, the metal parts expand due to the increase in temperature. Pre-adjusting the gap can avoid the gear meshing being too tight or too loose under hot conditions, so that the pressure distribution on the contact surface between the large gear and the cylinder is uniform, reducing vibration and local wear, and ensuring the smooth operation of the rotary cylinder.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 4As shown, this utility model provides a gear mounting mechanism, which includes a connecting pad 1, two fixing members 2, and a first mounting component 4. The connecting pad 1 is assembled between the rotating cylinder 8 and the large gear 9, and is connected to the rotating cylinder 8. The two fixing members 2 are respectively disposed on both axial sides of the large gear 9 and are located on the connecting pad 1. The fixing members 2 are provided with circumferential connecting members 3 on both circumferential sides of the large gear 9, and the circumferential connecting members 3 are also connected to the rotating cylinder 8. The first mounting component 4 connects the large gear 9 and the two fixing members 2.

[0032] A large gear 9 is fitted onto the outside of a rotating cylinder 8. A connecting pad 1 is provided between the rotating cylinder 8 and the large gear 9, and the connecting pad 1 is connected to the rotating cylinder 8. Fixing members 2 are respectively provided on opposite sides of the large gear 9. The fixing members 2 are connected to the large gear 9 through a first mounting component 4, and the fixing members 2 are also connected to the connecting pad 1. This connects the large gear 9 to the rotating cylinder 8 and limits and fixes its axial position. Circumferential connecting members 3 are respectively provided on both sides of the fixing members 2, and the circumferential connecting members 3 are also connected to the rotating cylinder 8. This connects the large gear 9 to the rotating cylinder 8 and limits and fixes its circumferential position. By simultaneously limiting and fixing the large gear 9 in both the circumferential and axial directions, the reliability of the connection between the large gear 9 and the rotating cylinder 8 is ensured. During the operation of the rotating cylinder 8, dynamic loads can be reduced, the risk of fatigue fracture can be reduced, and the possibility of connection failure between the rotating cylinder 8 and the large gear 9 can be reduced, ensuring the safety of the device.

[0033] The connection plate 1 is placed between the rotating cylinder 8 and the large gear 9, which can ensure a suitable clearance between the outer diameter of the rotating cylinder 8 and the inner diameter of the large gear 9, thus ensuring the stable operation of the equipment.

[0034] Furthermore, to ensure connection reliability, the connecting pad 1 is welded to the rotating cylinder 8, the fixing part 2 is welded to the connecting pad 1, and the circumferential connecting part 3 is welded to both the fixing part 2 and the rotating cylinder 8, thereby ensuring the overall connection strength. Of course, in different application scenarios, the above-mentioned welding connection method can also adopt detachable connection methods such as screw connection or snap connection to meet the usage requirements.

[0035] Of course, there are two fixing parts 2, which are located on both sides of the axial direction of the large gear 9. The large gear 9 is fixedly connected to the rotary cylinder 8 through the fixing parts 2. The fixing parts 2 also bear the axial force of the rotary cylinder 8 moving up and down, thereby preventing the large gear 9 from displacing along the axial direction of the rotary cylinder 8.

[0036] like Figures 1 to 4As shown, in some embodiments, the first mounting component 4 connects the large gear 9 and the two fixing members 2. The first mounting component 4 can be a welded part, welding and fixing the large gear 9 and the fixing members 2. The first mounting component 4 can also be a detachable connector. For example, the first mounting component 4 includes a first connector 41. The fixing members 2 and the large gear 9 are respectively provided with first connecting holes 42. The connecting ends of the first connector 41 pass through each of the first connecting holes 42 in sequence, and the connecting ends of the first connector 41 are connected to first fasteners 43. The large gear 9 and the fixing members 2 are connected by the first connector 41 and fastened by the first fasteners 43, thereby ensuring the reliability of the connection. The first connector 41 includes a first bolt or a first screw. In this embodiment, the first connector 41 is a first bolt, and the first fastener 43 is a first nut that is screwed into the first bolt. The first mounting component 44 is used to combine the large gear 9 and the fixing members 2 located on both sides of it into a whole, ensuring that the large gear 9 can drive the rotating cylinder 8 to rotate stably.

[0037] An internal thread is formed in the first connecting hole 42. The internal thread is used to engage with the external thread of the first bolt, further preventing the large gear 9 from moving relative to itself along its own axial direction due to the installation gap.

[0038] The connecting end of the first connector 41 is also connected to a second fastener 44, which abuts against the first fastener 43. The second fastener 44 further secures the connection between the large gear 9 and the fixing member 2. The second fastener 44 includes a second nut screwed onto the first bolt. The combination of the first nut and the second nut enhances the reliability of the connection and prevents the first bolt from loosening or breaking.

[0039] Furthermore, each of the two fasteners 2 has a first washer 45 on its opposite side, and the two first washers 45 respectively cooperate with the first connector 41 and the first fastener 43. The first washers 45 are provided at the first bolt and the first nut side, respectively. The provision of the first washers 45 increases the force-bearing area, disperses the preload of the first bolt, and can also play a role in preventing loosening under vibration or alternating loads.

[0040] In some embodiments, a reinforcing rib 5 is provided between the fixing member 2 and the connecting pad 1. The reinforcing rib 5 is provided to improve the connection strength between the fixing member 2 and the connecting pad 1, enhance rigidity, reduce deformation, and disperse stress.

[0041] Optionally, two reinforcing ribs 5 are provided, with each reinforcing rib 5 connected to one end of the fixing member 2, and the first mounting component 4 connected to the middle of the fixing member 2. The reinforcement ribs 5 not only ensure the stability of the fixing member 2, but also increase the axial force of the fixing member 2.

[0042] Among them, the reinforcing rib 5 can be a straight reinforcing rib, an arc reinforcing rib, an angular reinforcing rib, etc. In this embodiment, the reinforcing rib 5 adopts an angular reinforcing rib, which fits the fixing member 2 and the connecting pad 1 to increase the rigidity and connection strength at the corner.

[0043] like Figures 1 to 4 As shown, in some embodiments, the connecting pad 1 is provided with an adjustment component 6 on the side facing the large gear 9. The adjustment component 6 is used to adjust the gap between the outer diameter of the rotary cylinder 8 and the inner diameter of the large gear 9, so that the gap between the outer diameter of the rotary cylinder 8 and the inner diameter of the large gear 9 reaches the optimal working gap range, ensuring the smooth operation of the rotary cylinder 8.

[0044] Furthermore, the gear mounting mechanism also includes a second mounting component 7, which is detachably connected to the adjusting component 6 and the connecting pad 1. By setting the second mounting component 7, different adjusting components 6 can be assembled on the connecting pad 1 under different usage requirements, thereby adjusting the gap between the outer diameter of the rotary cylinder 8 and the inner diameter of the large gear 9, and improving the versatility of the device.

[0045] The adjusting component 6 includes an adjusting shim 61 disposed on the connecting shim 1, and an adjusting shim 62 disposed between the adjusting shim 61 and the connecting shim 1. During machining or installation, the rotary cylinder 8 and the large gear 9 may have dimensional tolerances or concentricity deviations. The gap can be finely adjusted by increasing or decreasing the thickness of the adjusting component 6. During equipment operation, the metal parts expand due to temperature rise; pre-adjusting the gap can prevent the gear meshing from being too tight or too loose under hot conditions, ensuring uniform pressure distribution on the contact surface between the large gear 9 and the cylinder, and reducing vibration and localized wear.

[0046] Adjusting shim 61 is used for large-range adjustments; coarse adjustments are achieved by replacing shims 61 with those of different thicknesses. Adjusting shims 62 are used for small-range adjustments; fine adjustments are achieved by replacing shims 62 with those of different thicknesses. Adjusting shims 62 are thin shims made of stainless steel or copper. For example, the adjustment thickness of adjusting shim 61 is at the centimeter level, while the adjustment thickness of adjusting shim 62 is at the millimeter level.

[0047] The second mounting component 7 includes a second bolt, a spring washer 72, and a flat washer 73. The second bolt is threaded through the adjusting component 6 and the connecting pad 1, and the adjusting component 6 and the connecting pad 1 are detachably connected. The spring washer 72 provides a continuous rebound force when the second bolt is tightened and undergoes elastic deformation, thus counteracting loosening caused by vibration, impact, or thermal deformation. The flat washer 73 disperses the compressive stress of the second bolt on the connecting surface, preventing surface scratches.

[0048] Reference Figures 1 to 4 As shown above, this application provides a gear mounting mechanism. A large gear 9 is sleeved on the outside of a rotating cylinder 8. A connecting pad 1 is connected to the rotating cylinder 8. Fixing members 2 are respectively provided on opposite sides of the large gear 9. The fixing members 2 are connected to the large gear 9 via a first mounting component 4 and are also connected to the connecting pad 1, thereby connecting the large gear 9 to the rotating cylinder 8 and limiting and fixing its axial position. Circumferential connecting members 3 are respectively provided on both sides of the fixing members 2. The circumferential connecting members 3 are also connected to the rotating cylinder 8, thereby connecting the large gear 9 to the rotating cylinder 8 and limiting and fixing its circumferential position. By simultaneously limiting and fixing the large gear 9 in both the circumferential and axial directions, the reliability of the connection between the large gear 9 and the rotating cylinder 8 can be ensured. During the operation of the rotating cylinder 8, the dynamic load can be reduced, the risk of fatigue fracture can be reduced, and the possibility of connection failure between the rotating cylinder 8 and the large gear 9 can be reduced, thus ensuring the safety of the device. This solves the problem that the preload of traditional bolts may gradually decrease due to vibration, thermal expansion, or material creep, causing relative displacement of the flange surface and leading to bolt loosening or breakage.

[0049] like Figures 1 to 4 As shown, this utility model also provides a horizontal rotary device, including a rotary cylinder 8, a transmission device, and the gear mounting mechanism described in the above embodiment. The transmission device includes a rotatable pinion and a large gear 9 meshing with the pinion. The large gear 9 is sleeved on the outer circumference of the rotary cylinder 8 and is mounted on the rotary cylinder 8 through the gear mounting mechanism. The rotation of the pinion drives the rotation of the large gear 9, which in turn drives the rotation of the rotary cylinder 8, thus realizing the operation of the horizontal rotary device.

[0050] Of course, in order to ensure the connection effect between the rotating cylinder 8 and the large gear 9, multiple sets of gear mounting mechanisms are set, and each gear mounting mechanism is evenly spaced along the circumference of the large gear 9.

[0051] Horizontal rotary equipment includes, but is not limited to, horizontal steaming and frying pans, horizontal rotary dryers, and horizontal oil softening and drying machines.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
