Description

Technical Field

[0001] The present invention belongs to the technical field of speed reducers, and in particular relates to an environmentally friendly and energy-saving oil-seal-free integrated flange box speed reducer. Background Art

[0002] In today's booming modern industry, reducers, as key components in the transmission systems of various mechanical equipment, are widely used in a wide range of fields, including metallurgy, mining, chemical industry, construction, transportation, and many other fields. However, traditional reducers have exposed many problems in actual use and are in urgent need of innovation.

[0003] First, in terms of structural design, the input flange and housing of conventional reducers are often separated. This split design inevitably creates a gap between the two. During operation, the reducer is subject to strong external forces transmitted by components such as pulleys. Under long-term external impact, the gap between the housing and flange gradually widens, leading to frequent oil leakage. Large reducers, in particular, require higher mechanical strength, and the drawbacks of the split structure are even more prominent. This makes the oil leakage problem difficult to effectively resolve, seriously affecting the normal operation and service life of the reducer. Secondly, regarding bearing sealing performance, traditional rolling bearings consist of an outer guide rail, an inner guide rail, and rolling elements. Although lubricating grease is filled between the inner and outer guide rails, due to structural design flaws, the sealing performance is poor. In high-intensity working environments, especially when the external forces transmitted by the pulley are large, the lubricating grease is prone to leakage. This not only wastes lubricant, but also causes increased bearing wear due to insufficient lubrication, affecting the normal operation of the bearing and reducing the overall performance of the reducer. Finally, regarding flange strength and sealing, for medium-to-large split reducers in applications such as textile machinery, the significant force exerted by the external pulley creates significant pulling forces on the reducer during acceleration and deceleration. This pulling force can create gaps between the input and output flanges and the housing, leading to oil leakage. Traditional flange designs lack sufficient thickness and a small load-bearing surface, making them unable to withstand this pulling force. This leads to recurring gaps and oil leakage, severely restricting the reducer's stable operation under complex operating conditions. Summary of the Invention

[0004] In order to solve the problems of the above-mentioned split structure of the input flange and the casing body causing oil leakage due to enlarged gaps, poor bearing sealing performance causing lubricating grease leakage, and insufficient flange strength causing gaps under the action of pulling force leading to oil leakage, the present invention provides an environmentally friendly and energy-saving oil-seal-free integrated flange box reducer.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: an environmentally friendly and energy-saving oil-seal-free integrated flange box reducer, comprising a reduction box body, wherein a worm cavity and a worm wheel cavity communicating with each other are opened in the reduction box body, and a driving mechanism is provided in the reduction box body; The driving mechanism includes a worm rotatably mounted in the worm cavity, and a worm wheel rotatably mounted in the worm wheel cavity; Both ends of the worm and the worm wheel are fixedly sleeved with bearing assemblies, and the bearing assembly includes a bearing body and an oil blocking member, wherein the bearing assembly on the worm is embedded in the worm cavity, and the bearing assembly on the worm wheel is embedded in the worm wheel cavity; An input flange is provided at one opening end of the worm cavity; The two end openings of the worm gear cavity are provided with detachable output flanges.

[0006] Furthermore, the input flange is integrally cast on the reduction gearbox body.

[0007] Furthermore, the bearing body is composed of an outer guide rail, an inner guide rail and a rolling body, the inner guide rail is embedded in the outer guide rail, and the rolling body is arranged between the inner wall of the outer guide rail and the outer wall of the inner guide rail.

[0008] Furthermore, the oil-blocking member comprises two symmetrically arranged groups of rubber rings, the two groups of rubber rings being symmetrically arranged on both sides of the rolling element, and the outer edges and inner edges of the rubber rings being connected to the outer guide rail and the inner guide rail respectively; The outer edge and inner edge of the rubber ring are respectively provided with an outer edge clamping groove and an inner edge clamping groove; The outer guide rail, the inner guide rail, the rolling element and the rubber ring respectively share the same central axis.

[0009] Furthermore, an upper sliding groove is provided in the middle of the inner wall of the outer guide rail, and upper clamping grooves are provided on both sides thereof; The outer wall of the inner guide rail is provided with a lower sliding groove at a position corresponding to the upper sliding groove, and lower clamping grooves are provided on both sides thereof at positions corresponding to the upper clamping grooves. The cross-sections of the upper sliding groove and the lower sliding groove are arc-shaped, matching the shape of the rolling body; The rolling body is rotatably arranged in a chute formed by an upper chute and a lower chute; The outer edge clamping groove of the rubber ring is clamped in the upper clamping groove, and the inner edge clamping groove is clamped in the lower clamping groove.

[0010] Furthermore, a copper sheet is installed on the inner side of the rubber ring, and the thickness of the copper sheet is 0.2-0.5 mm; Lubricating grease is filled between the rubber ring and the rolling element.

[0011] Furthermore, the worm and the worm wheel are meshed with each other.

[0012] Furthermore, connecting flanges are symmetrically fixed on the front and rear sides of the reduction gear box body, the connecting flanges are arranged around the central axis of the worm gear, and 6-12 screw holes are evenly distributed on the connecting flanges; The output flange is fixed to the corresponding screw holes of the connecting flange by means of bolts.

[0013] Furthermore, thickening parts are fixed on the inner sides of the input flange and the output flange respectively.

[0014] Furthermore, the other end of the worm cavity is covered and connected with a blind cover, and the blind cover is sealed to the reduction gear box body.

[0015] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects: 1. The input flange and housing of conventional reducers are often separated, resulting in a gap between them. This environmentally friendly and energy-saving oil-seal-free integrated flange housing reducer adopts a one-piece casting design, integrating the input flange with the reducer housing and other structures. This fundamentally eliminates the gap risks associated with the split structure, effectively preventing oil leakage caused by gaps widening due to external forces. It also enhances the stability and strength of the overall structure. Even when used on large reducers, it can maintain stable performance, thereby improving the reliability and service life of the reducer.

[0016] 2. Regarding the rubber ring design, a typical bearing body consists of an outer rail, an inner rail, and rolling elements. Although lubricant is present between the inner and outer rails, due to structural issues, oil leakage is significant under high-intensity loads, especially when the pulleys exert significant force. This reducer has adjusted the cross-section of the bearing body and added a specially constructed rubber ring with a copper sheet mounted on the inside. The rubber rings are symmetrically positioned on either side of the rolling element, with their outer and inner edges connected to the outer and inner rails via outer and inner edge slots, respectively. This ensures a secure installation, enhances sealing, and effectively reduces lubricant leakage.

[0017] 3. Regarding the design of thickening components, for medium-to-large split reducers in fields such as textile machinery, the strong force of the external pulley exerts a significant pulling force on the reducer during acceleration and deceleration. This can create gaps between the flange and the housing, leading to oil leakage. This reducer features thickening components fixed to both the input and output flanges, increasing the flange thickness by 5-20%. This increases the load-bearing area of ​​the input and output flanges without compromising the overall product structure, reducing the pulling effect of the pulleys and minimizing or even eliminating gaps. This not only solves the oil leakage problem but also improves the structural strength of the flanges, ensuring stable operation of the reducer under complex operating conditions.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0022] Unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. The present invention is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-13 As shown, the present invention provides an environmentally friendly and energy-saving oil-seal-free integrated flange box reducer, including a reduction box body 1, in which a worm cavity 11 and a worm wheel cavity 12 that are interconnected are opened, and a driving mechanism 2 is provided in the reduction box body 1; the driving mechanism 2 includes a worm 21 rotatably mounted in the worm cavity 11, and a worm wheel 22 rotatably mounted in the worm wheel cavity 12; the worm 21 and the worm wheel 22 are meshed with each other, and when the worm 21 rotates, the worm wheel 22 is driven to rotate synchronously, and the worm 21 meshes with the gear teeth of the worm wheel 22 through the spiral tooth surface, and transmits the rotational motion to the worm wheel 22. Due to the tooth ratio of the worm 21 and the worm wheel 22, the speed is reduced and the torque is amplified to complete the reduction transmission. The tooth surfaces of the two are precisely processed to ensure the smoothness and efficiency of the transmission; Both ends of the worm 21 and the worm wheel 22 are fixedly sleeved with bearing assemblies 3, and the bearing assembly 3 includes a bearing body 31 and an oil blocking member 32, wherein the bearing assembly 3 on the worm 21 is embedded in the worm cavity 11, and the bearing assembly 3 on the worm wheel 22 is embedded in the worm wheel cavity 12; an input flange 4 is provided at the opening of one end of the worm cavity 11, and the input flange 4 is integrally cast on the reduction box body 1. The integrated input flange eliminates the connection gap, so that the overall rigidity of the box body is increased by more than 30%, and the sealing performance can still be maintained under vibration conditions; the gap hidden danger caused by the split structure is eliminated, and the The traditional bolt connection solves the problem of loosening of the sealing surface due to vibration, thereby effectively avoiding oil leakage caused by the enlargement of the gap due to external force; the other end cover of the worm cavity 11 is connected with a blind cover 8, and the blind cover 8 and the reduction gear box body 1 are sealed. The blind cover 8 uses a nitrile rubber sealing ring and an interference fit with the flange surface of the box body to form a radial seal, which is used to effectively protect the bearing assembly 3 and related transmission components at the end of the worm 21, prevent external dust and impurities from entering, and avoid leakage of internal lubricating grease; removable output flanges 5 are provided at the openings at both ends of the worm gear cavity 12, which are convenient for flexible disassembly and replacement of the adapted output flange 5 according to the connection requirements of different load equipment.

[0024] like Figure 2-9 As shown, the bearing body 31 is composed of an outer guide rail 311, an inner guide rail 314 and a rolling element 317. The inner guide rail 314 is embedded in the outer guide rail 311, and the rolling element 317 is arranged between the inner wall of the outer guide rail 311 and the outer wall of the inner guide rail 314. The rolling motion of the rolling element 317 can flexibly adapt to the relative displacement between the inner guide rail 314 and the outer guide rail 311, making the rotation of the inner guide rail 314 smoother, reducing friction, ensuring rotation flexibility and load-bearing capacity, and reducing maintenance costs. It has significant advantages and provides an important guarantee for the efficient, stable and long-term operation of the reducer. The inner guide rail 314 rotates relative to the outer guide rail 311 through the rolling of the rolling element 317, thereby ensuring the flexible rotation of the worm 21 and the worm wheel 22. The oil-blocking member 32 includes two symmetrically arranged sets of rubber rings 321, one on each side of the rolling element 317. The outer and inner edges of the rubber rings 321 are connected to the outer guide rail 311 and the inner guide rail 314, respectively, forming a closed cavity. The rolling element 317 converts the sliding friction between the inner and outer guide rails 314, 311 into rolling friction. The outer and inner edges of the rubber rings 321 are respectively provided with outer edge retaining grooves 322 and inner edge retaining grooves 324. The outer guide rail 311, the inner guide rail 314, the rolling element 317, and the rubber rings 321 share the same central axis, ensuring that all components maintain coaxiality during operation and reducing wear. A copper sheet 323 is installed inside the rubber ring 321. The thickness of the copper sheet 323 is 0.2-0.5mm. The copper sheet 323 is installed closely to the inside of the rubber ring 321. This not only enhances the structural strength of the rubber ring 321, but also dissipates the heat generated by the operation of the bearing through the thermal conductivity of the metal material, delaying the aging of the grease, enhancing the sealing performance and assisting in heat dissipation. Lubricating grease is filled between the rubber ring 321 and the rolling element 317. The lubricating grease is a fully synthetic high-temperature grease with good oxidation resistance and extreme pressure performance. It can effectively reduce the friction loss of the rolling element 317 during operation, provide lubrication for the rolling element 317, and block the leakage channel through the viscosity of the grease.

[0025] like Figure 8 、 10 As shown in FIG13 , an upper sliding groove 312 is provided in the middle of the inner wall of the outer guide rail 311, and upper clamping grooves 313 are provided on both sides thereof; a lower sliding groove 315 is provided on the outer wall of the inner guide rail 314 at a position corresponding to the upper sliding groove 312, and lower clamping grooves 316 are provided on both sides thereof corresponding to the position of the upper clamping groove 313. The cross sections of the upper sliding groove 312 and the lower sliding groove 315 are arc-shaped, which match the outer shape of the rolling body 317; the rolling body 317 is rotatably arranged in the sliding groove formed by the upper sliding groove 312 and the lower sliding groove 315; the outer edge clamping groove 322 of the rubber ring 321 is clamped in the upper clamping groove 313, and the inner edge clamping groove 324 of the rubber ring 321 is clamped in the lower clamping groove 316, and the rubber ring 321 is clamped in the lower clamping groove 316 by the cooperation of the clamping groove 322 and the clamping groove. The secure installation of the rubber ring 321 creates a closed space to prevent grease leakage. The outer edge groove 322 of the rubber ring 321 and the upper engaging groove 313, as well as the inner edge groove 324 and the lower engaging groove 316, form dual radial and axial positioning. This ensures that the rubber ring is securely installed while preventing accelerated aging of the rubber due to excessive extrusion. The coordinated structure of the groove and engaging groove enables the rubber ring 321 to maintain a sealed posture even when the rolling element is running at high speed, improving leakage prevention reliability compared to traditional flat adhesive types. Through the triple protection of integrated casting, combined sealing of the rubber ring 321 and the copper sheet 323, and self-sealing of the grease, the problem of lubricating oil leakage caused by aging oil seals in traditional reducers is completely eliminated, thus avoiding pollution to the working environment.

[0026] like Figure 1-3As shown in 5-7, the front and rear sides of the reduction gearbox body 1 are symmetrically fixed with connecting flanges 6, which are arranged around the central axis of the worm gear 22, thereby avoiding additional radial force caused by assembly eccentricity, ensuring the coaxiality of the output flange 5 and the worm gear 22 after installation, and ensuring accurate and stable transmission. There are 6-12 screw holes evenly distributed on the connecting flange 6, which provide multiple connection points for the fixation of the output flange 5, forming an annular force structure, and enhancing the stability of the connection. When the output flange 5 is tightened by bolts, the pre-tightening force at each screw hole is evenly distributed along the circumference, so that the contact surface of the output flange 5 and the connecting flange 6 generates a uniform pressing force, which effectively offsets the axial force and radial force generated when the worm gear 22 is running; The output flange 5 is fixed to the corresponding screw holes of the connecting flange 6 by bolts, and is used to fix the output flange 5 on the reduction gear box body 1; thickening parts 7 are fixed to the inner sides of the input flange 4 and the output flange 5 respectively, and the thickness of the input flange 4 and the output flange 5 is increased by 5-20% through the thickening parts 7; the thickening parts 7 are made of high-strength wear-resistant material and are used to replace traditional oil seals, thereby reducing the need for downtime and replacement due to oil seal wear, and are tightly embedded in the corresponding worm cavity 11 and worm wheel cavity 12, respectively, which not only has a good sealing effect but also improves the strength of the flange structure.

[0027] When used specifically, 1. Assembly and installation of reducer 1. Assembly of bearing assembly 3 Pre-install the rubber ring 321 and the copper sheet 323: Check the outer edge slot 322 and inner edge slot 324 of the rubber ring 321 and the surface of the copper sheet 323 to ensure that there is no damage or deformation. Fit the copper sheet 323 to the inner side of the rubber ring 321. To assemble the rubber ring 321 with the bearing body 3, align the outer edge groove 322 of the rubber ring 321 with the upper engagement groove 313 of the outer guide rail 311, and the inner edge groove 324 with the lower engagement groove 316 of the inner guide rail 314. Gently press the rubber ring 321 until it is fully embedded in the bearing assembly 3, ensuring that the rubber ring 321 is positioned both radially and axially with the outer and inner guide rails 311 and 314. Grease filling: Fully synthetic high-temperature grease is injected into the closed cavity on both sides of the rolling element 317, and the grease filling amount does not exceed 80% of the cavity volume. 2. Assembly of the reduction gearbox Installation of the worm 21 and worm wheel 22: Insert the bearing assemblies 3 at both ends of the worm 21 into the worm cavity 11, ensuring that the outer guide rail 311 fits tightly with the housing seat hole. Insert the bearing assemblies 3 at both ends of the worm wheel 22 into the worm wheel cavity 12, ensuring that the worm wheel 22 and worm 21 are properly engaged. Installation of input flange 4 and blind cover 8: Input flange 4 is fixed to reduction gearbox 1 through integral casting, ensuring a seamless connection. Blind cover 8 is installed at the other end of worm cavity 11. A nitrile rubber sealing ring is used for interference fit between blind cover 8 and reduction gearbox 1 to form a radial seal. Installation of output flange 5: Select the appropriate output flange 5 based on the connection requirements of the load equipment. Fasten the output flange 5 to the corresponding screw holes of the connection flange 6 with bolts, and tighten the bolts evenly in diagonal order to ensure uniform force. 2. Operation of reducer 1. Power Input and Transmission: Connect the external power input component to the input flange 4, and the working component to the output flange 5. After the power is input through the worm 21, it is decelerated by the meshing transmission between the worm 21 and the worm wheel 22, and then transmitted to the working component through the output flange 5. 2. Monitoring the operating status of bearing assembly 3: During operation, rolling elements 317 convert sliding friction between inner and outer guide rails 314 and 311 into rolling friction, reducing frictional losses. The combined structure of rubber ring 321 and copper sheet 323 ensures sealing performance and prevents lubricant leakage. 3. Maintenance of reducer 1. Disassembly and replacement of bearing assembly 3 Preparation before disassembly: Disconnect the power input. If you need to disassemble the bearing assembly 3 at the worm 21 end, you must first remove the blind cover 8; if you need to disassemble the bearing assembly 3 at the worm wheel 22 end, you must remove the output flange 5. Removal of the bearing assembly 3: Use a puller tool to slowly pull the bearing body 31 out of the housing seat hole to avoid damaging the guide rail or the housing seat hole. To replace rubber ring 321: Use a slender flat-head screwdriver to gently pry the outer edge slot 322 of rubber ring 321 out of the upper engaging slot 313. Similarly, release the inner edge slot 324 from the lower engaging slot 316 of the inner guide rail 314. If copper sheet 323 is stuck, soften the grease with alcohol and then peel it off. Reassembly: Clean the snap-in groove and the guide rail surface. Apply a small amount of grease to aid installation before replacing the new rubber ring 321. Reassemble the bearing assembly 3 according to the above steps and fill it with grease. 2. Regular maintenance Lubrication inspection: Check the lubricating grease status every 2000 hours of operation, and add or replace the fully synthetic high-temperature grease if necessary. Inspection of the rubber ring 321 and the copper sheet 323: Regularly check the elasticity of the rubber ring 321 and the wear of the copper sheet 323. If aging or deformation is found, replace them in time. Flange connection inspection: Check the bolt tightness of the input flange 4, output flange 5 and connecting flange 6 to ensure that there is no looseness.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
