Description

Technical Field

[0001] This application relates to the field of speed reducer design and manufacturing technology, and in particular to a stainless steel speed reducer and its assembly equipment. Background Technology

[0002] Planetary gearboxes are widely used in industrial automation production lines due to their compact structure, large transmission ratio, and strong load-bearing capacity. In specific application scenarios such as food and beverage processing, marine ship propulsion, and chemical reactor stirring, the equipment is exposed to high humidity, high salt spray, or acid and alkali corrosion environments for a long time. Gearboxes made of cast iron or carbon steel are prone to problems such as housing corrosion, bearing jamming, and seal failure, which seriously affect the service life of the equipment and production safety. Therefore, the industry has gradually begun to use stainless steel materials such as 304 or 316L to manufacture gearbox housings and end covers to improve the corrosion resistance of the products.

[0003] However, when stainless steel is introduced into the manufacturing of planetary gearboxes, especially in the assembly of core components, stainless steel is harder than ordinary carbon steel. During the interference fit process, if there is a slight deviation between the planetary carrier and the end cover hole, it is very easy to cause scratches or seizing of the mating surfaces, resulting in the scrapping of expensive workpieces. Meanwhile, most existing assembly equipment uses a constant pressing speed. For stainless steel, a difficult-to-process material, this rigid impact can easily break through the material's yield limit. When the pressing force exceeds the threshold, the traditional mechanical connection structure cannot cut off the power instantly, often causing the planetary carrier to bend or the end cap to deform.

[0004] In other words, existing technologies have the following technical problems: when assembling stainless steel speed reducers using ordinary speed reducer assembly equipment, overpressure damage can easily occur due to misalignment. Therefore, to address the above problems, a stainless steel speed reducer and its assembly equipment are proposed. Summary of the Invention

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] Please see Figure 2 As shown, in a specific embodiment of this application, a stainless steel speed reducer is disclosed, including a speed reducer body 1; The reducer body 1 is composed of a stainless steel end cover 101, a fixed bearing 102 and a planetary carrier 103; A fixed bearing 102 is fixedly installed in the inner cavity of the stainless steel end cap 101. The fixed bearing 102 has an inner hole 1021, which is used to form an interference fit with the lower outer circumferential surface of the planet carrier 103 to support the rotational movement of the planet carrier 103.

[0022] In a preferred embodiment of this application, an annular portion 104 is fixedly connected to the upper end of the planet carrier 103. A plurality of planet gear mounting shafts 1042 are provided on the upper surface of the annular portion 104. The plurality of planet gear mounting shafts 1042 are evenly distributed in an annular array for mounting planetary gears through bearings to construct a planetary gear transmission structure. Furthermore, in order to enable pre-positioning during subsequent assembly, a positioning groove 1041 is provided at the center of the annular portion 104, which is used to cooperate with the positioning post 804 in the assembly equipment to achieve axial pre-positioning during the assembly process.

[0023] In addition, to reduce the difficulty of alignment during the press-fitting process, the bottom of the planetary carrier 103 is chamfered and the inner hole 1021 is chamfered. The two work together to guide and correct deviations during the press-fitting process.

[0024] Please see Figure 1 As shown, in a preferred embodiment of this application, this application discloses a stainless steel reducer assembly equipment, including: a fixed base 2, and an end cover positioning mechanism 3 fixedly connected to the upper surface of the fixed base 2. The end cover positioning mechanism 3 is used to limit and fix the stainless steel end cover 101 from the side and axial direction. A pressing assembly drive mechanism 4 is also fixedly connected to the upper surface of the fixed base 2. One end of the pressing assembly drive mechanism 4 is provided with an adjusting support arm 6, and one end of the adjusting support arm 6 is provided with a planetary carrier clamping mechanism 8. The planetary carrier clamping mechanism 8 is used to perform centripetal clamping on the annular part 104 of the planetary carrier 103 from the outer periphery. A dual-axis floating mechanism 7 is also provided between the adjusting support arm 6 and the planetary carrier clamping mechanism 8, which allows the planetary carrier clamping mechanism 8 to make small displacement compensation in the X and Y axis directions in the horizontal plane to adapt to the centering error during assembly. An overpressure protection mechanism 5 is also provided between the pressing assembly drive mechanism 4 and the adjusting support arm 6. This mechanism is used to mechanically slip when the downward pressure exceeds a preset threshold, thereby cutting off the transmission of driving force and preventing damage to the workpiece or equipment.

[0025] This application designs a dedicated assembly equipment and a suitable reducer structure. The dual-shaft floating mechanism 7 can automatically compensate for the axial deviation between the planetary carrier 103 and the stainless steel end cap 101 in the early stage of press fitting, thereby reducing the initial frictional resistance.

[0026] The overall technical solution formed by the overpressure protection mechanism 5, the dual-axis floating mechanism 7, and the planetary carrier clamping mechanism 8 helps to reduce the assembly difficulty of stainless steel interference fits on the one hand, and can cut off the power in time when jamming occurs, thereby reducing the scrap rate.

[0027] The integrated technical solution formed by the pressing assembly drive mechanism 4, the planetary carrier clamping mechanism 8, and the auxiliary spraying component 9 can achieve lubrication before pressing, reducing adhesive wear on the stainless steel surface, and achieve automated spraying by utilizing the mechanical linkage of the pressing action. It is particularly suitable for the precision assembly of large batches of stainless steel reducers.

[0028] In a preferred embodiment of this application, see [reference] Figure 1 and Figure 3 As shown, the end cap positioning mechanism 3 includes a positioning cylinder 301, a positioning clamping block 302, and a reference baffle 303.

[0029] A reference baffle 303 is fixedly connected to one side of the upper surface of the fixed base 2. The reference baffle 303 is used to provide a rigid reference surface for the axial positioning of the stainless steel end cap 101. The reference baffle 303 is in linear contact or surface contact with the side of the stainless steel end cap 101, which plays a role in restricting the axial movement and circumferential rotation of the stainless steel end cap 101.

[0030] Positioning cylinders 301 are fixedly connected to both sides of the upper surface of the fixed base 2. A positioning clamping block 302 is fixedly connected to one end of the positioning cylinder 301. The positioning clamping block 302 is used to apply clamping force from both sides of the stainless steel end cover 101 so that it is firmly against the reference baffle 303.

[0031] With this technical solution, when the positioning cylinder 301 extends, it can drive the positioning clamp 302 to move synchronously towards the center, thereby pressing and fixing the stainless steel end cap 101 to the side of the reference baffle 303, which plays a role in rapid positioning and clamping, and ensures the reference consistency of subsequent pressing processes.

[0032] In one specific embodiment of this application, see [reference]. Figure 4 As shown, the pressing assembly drive mechanism 4 includes a support guide rod 401, a lifting slider 402, and an upper fixed plate 403; There are two support guide rods 401. The upper ends of the two support guide rods 401 are fixedly connected to the upper fixing plate 403. The two support guide rods 401 are fixedly connected to the upper surface of the fixed base 2 to form a stable portal frame structure. Lifting sliders 402 are slidably connected to the two support guide rods 401. A hydraulic cylinder 404 is fixedly installed on the upper surface of the upper fixed plate 403. The output shaft end of the hydraulic cylinder 404 is fixedly connected to the lifting slider 402, and is used to drive the lifting slider 402 to reciprocate linearly along the axial direction of the support guide rods 401 by the extension and retraction of the output shaft.

[0033] With this technical solution, when the output shaft of the hydraulic cylinder 404 extends downward, it can push the lifting slider 402 to slide downward along the support guide rod 401, thereby driving the adjusting support arm 6 connected to it and the planetary carrier clamping mechanism 8 below to move downward as a whole, and work together with the end cover positioning mechanism 3 fixed below to realize the press-fit assembly of the planetary carrier 103 and the stainless steel end cover 101.

[0034] In a preferred embodiment of this application, see [reference] Figure 5 As shown, the adjusting arm 6 includes a support arm 601, an adjusting slider 602, and an adjusting screw 603; The support arm 601 has a sliding groove cavity inside, and an adjusting slider 602 is slidably connected in the sliding groove cavity of the support arm 601.

[0035] An adjusting screw 603 is rotatably connected between the two sides of the inner cavity of the support arm 601. The adjusting screw 603 passes through the adjusting slider 602 and is threadedly engaged with the adjusting slider 602. A servo motor 604 is fixedly installed on one side of the support arm 601. The end of the output shaft of the servo motor 604 is fixedly connected to one end of the adjusting screw 603 to form a screw drive structure.

[0036] With the above technical solution, when the servo motor 604 receives the control signal and starts, it can drive the adjusting screw 603 to rotate around its own axis, thereby driving the adjusting slider 602, which is threaded to it, to make linear displacement along the inner cavity of the slide groove of the support arm 601, thereby driving the dual-axis floating mechanism 7 and the planetary carrier clamping mechanism 8 connected below to adjust the horizontal position, adapt to planetary carriers 103 of different specifications and sizes or compensate for installation errors.

[0037] In a preferred embodiment of this application, see [reference] Figure 4 and Figure 5 As shown, the overpressure protection mechanism 5 includes a guide rail frame 501, a protection slider 502, and a pressure slider 503; A linear guide rod 504 is fixedly connected to one side of the guide rail frame 501. A pressure slider 503 is slidably connected to the linear guide rod 504 to form a linear moving pair. One end of a pressure buffer spring 505 is fixedly connected to one side of the pressure slider 503, and the other end of the pressure buffer spring 505 is fixedly connected to the guide rail frame 501.

[0038] The adjusting support arm 6 is fixedly connected to the pressure slider 503.

[0039] Through this technical solution, when the pressing resistance is transmitted to the pressure slider 503, it can overcome the preload of the pressure buffer spring 505, thereby causing the pressure slider 503 to move relative to the linear guide rod 504, gradually compressing the pressure buffer spring 505, so that the downward pressure increases gradually, playing a role in buffering and shock absorption, and avoiding damage to the inner hole of the stainless steel end cap 101 caused by rigid impact.

[0040] Further, see Figure 5 As shown, a guide rail 5011 is provided on one side of the guide rail frame 501. A protective slider 502 is slidably connected to the guide rail 5011. The protective slider 502 has an inner cavity. A round-headed pin 506 is slidably connected in the inner cavity of the protective slider 502. One end of the round-headed pin 506 is hemispherical or arc-shaped. A circular groove matching the head shape of the round-headed pin 506 is provided on one side of the guide rail frame 501 to realize a detachable positioning connection between the protective slider 502 and the guide rail frame 501. One side of the round-headed pin 506 is fixedly connected to an overpressure locking spring 507. When the overpressure locking spring 507 is in a compressed state, a fixing bolt 508 is also threadedly connected to the protective slider 502. One end of the fixing bolt 508 contacts the overpressure locking spring 507 and is used to adjust the pre-compression of the overpressure locking spring 507 by adjusting the screwing depth of the fixing bolt 508, thereby setting the unlocking threshold.

[0041] The protective slider 502 and the lifting slider 402 are fixedly connected to form a power input end.

[0042] Through the above technical solution, the preload of the overpressure locking spring 507 can be adjusted by turning the fixing bolt 508, thereby adjusting the locking force of the round-headed pin 506 locked in the circular groove, and thus setting the maximum shear force threshold that the mechanism can withstand.

[0043] Specifically, when the pressing resistance exceeds the threshold, the lateral shear force on the round-headed pin 506 is greater than the locking force, causing the round-headed pin 506 to retract and disengage from the circular groove, resulting in relative slippage between the protective slider 502 and the guide rail 501. This provides overload protection and prevents irreversible plastic deformation of the planetary carrier 103 or the stainless steel end cap 101 due to excessive pressure.

[0044] In one specific embodiment of this application, see [reference]. Figure 7 and Figure 8 As shown, the planetary carrier clamping mechanism 8 includes a base 801, a telescopic arm 802, and a gripper 803; In order to achieve the synchronous movement function of the two grippers 803, the base 801 is provided with an inner cavity. Telescopic arms 802 are slidably connected to both sides of the inner cavity of the base 801. One end of each telescopic arm 802 is fixedly connected to a gripper 803. The gripper 803 is used to radially clamp the annular part 104 of the planetary carrier 103.

[0045] As a preferred technical solution, the clamping working surface of the gripper 803 is set as an arc-shaped clamping surface that matches the outer circumferential surface of the annular portion 104.

[0046] As a further optimization, an elastic pad can also be embedded on the arc-shaped clamping surface. The elastic pad is preferably made of polyurethane or hard rubber and has a grid-like anti-slip texture on its surface.

[0047] Through this technical solution, the elastic pad can play a role in buffering and absorbing shock, absorbing the impact load in the initial stage of pressing, while increasing the friction force to prevent the planetary carrier 103 from slipping circumferentially when it is clamped, thus ensuring the reliability of the fit between the positioning pin 804 and the positioning groove 1041.

[0048] A positioning post 804 is also fixedly connected to the bottom surface of the base 801. The positioning post 804 is used to engage with the positioning groove 1041 of the annular part 104, so that the planetary carrier 103 can maintain concentricity with the positioning post 804 when it is clamped, and prevent eccentricity.

[0049] Through the above technical solution, by driving the telescopic arm 802 to extend and retract, the gripper 803 can be driven to open and close, thereby realizing the rapid gripping and release of the planetary carrier 103. The cooperation between the positioning post 804 and the positioning groove 1041 plays a pre-positioning role, which helps to improve the coaxiality in the initial stage of press fitting.

[0050] Furthermore, the base 801 is provided with a drive unit for driving the telescopic arm 802 to move synchronously in opposite directions. The drive unit includes a threaded sleeve 805, a double helical screw 806, and a drive motor 807. The base 801 has an internal cavity. A threaded sleeve 805 is fixedly connected to the internal cavity of the telescopic arm 802. A double helical screw 806 is rotatably connected to the internal cavity of the base 801. The two ends of the double helical screw 806 are threadedly connected to the two threaded sleeves 805 respectively, forming a bidirectional screw drive structure.

[0051] A drive motor 807 is also fixedly installed on the side wall of the base 801. The output shaft end of the drive motor 807 is connected to the double helical screw 806 to form a rotary power input structure.

[0052] With this technical solution, when the drive motor 807 starts, it can drive the double helical screw 806 to rotate, which in turn drives the telescopic arms 802 on both sides to retract inward or extend outward simultaneously through the threaded sleeve 805, realizing the synchronous centripetal clamping or releasing of the gripper 803, ensuring the uniformity of the clamping force distribution and the stability of the clamping center.

[0053] In a preferred embodiment of this application, see [reference] Figure 7 As shown, the dual-axis floating mechanism 7 includes an X-axis fixed frame 701, an X-axis guide rod 702, an X-axis slider 703, a Y-axis fixed frame 705, a Y-axis guide rod 706, and a Y-axis slider 707; The X-axis fixing bracket 701 is fixedly installed on the bottom surface of the adjusting slider 602. The X-axis guide rod 702 is fixedly connected to the inner side of the X-axis fixing bracket 701. The X-axis slider 703 is slidably connected to the X-axis guide rod 702, forming a linear moving pair in the X-axis direction. One end of an X-axis spring 704 is fixedly connected to both side walls of the X-axis slider 703, and the other end of the X-axis spring 704 is fixedly connected to the inner side of the X-axis fixing frame 701, forming an elastic reset structure in the X-axis direction.

[0054] A Y-axis mounting bracket 705 is fixedly connected to the bottom surface of the X-axis slider 703. A Y-axis guide rod 706 is fixedly connected to the inner side of the Y-axis mounting bracket 705. A Y-axis slider 707 is slidably connected to the Y-axis guide rod 706, forming a linear motion pair in the Y-axis direction.

[0055] Y-axis slider 707 has one end of Y-axis spring 708 fixedly connected to each of its two side walls. The other end of Y-axis spring 708 is fixedly connected to Y-axis fixing frame 705 to form an elastic reset structure in the Y-axis direction. Y-axis slider 707 is fixedly connected to planetary carrier clamping mechanism 8.

[0056] Through the above technical solution, when the chamfer at the lower end of the planetary carrier 103 is not fully aligned with the chamfer at the inner hole 1021, as the pressing assembly drive mechanism 4 presses down, the lateral component force can overcome the elastic force of the X-axis spring 704 or the Y-axis spring 708, thereby driving the X-axis slider 703 or the Y-axis slider 707 to slide along the guide rod, so that the chamfer at the bottom of the planetary carrier 103 and the chamfer at the inner hole 1021 interact, automatically offset and correct the position, adapt to the axial position of the inner hole 1021, thereby completing adaptive alignment and reducing the risk of jamming caused by installation eccentricity.

[0057] As a preferred technical solution, friction damping is provided between the X-axis slider 703 and the X-axis guide rod 702, and friction damping is provided between the Y-axis slider 707 and the Y-axis guide rod 706.

[0058] This technical solution, through the setting of friction damping, can delay the movement of the slider, prevent it from generating high-frequency oscillations under the action of elastic restoring force, help maintain the stability of the pressing process, and avoid the generation of vibration marks on the stainless steel surface due to excessive instantaneous impact force.

[0059] In a preferred embodiment of this application, see [reference]. Figure 9 As shown, it also includes an auxiliary spraying assembly 9, which includes a bent pipe 901, a nozzle 902 and a fixed cylinder 903; The positioning post 804 has an internal cavity. Several bent tubes 901 are fixedly connected to the arc-shaped wall of the positioning post 804. A nozzle 902 is fixedly installed at one end of the bent tube 901, forming a spray structure distributed on the outer circumference of the positioning post 804. The fixed cylinder 903 is fixedly installed at the bottom surface of the lifting slider 402. A piston 904 is slidably connected in the inner cavity of the fixed cylinder 903. One end of the connecting rod 905 is fixedly connected to the bottom surface of the piston 904. The other end of the connecting rod 905 passes through the bottom wall of the inner cavity of the fixed cylinder 903 and extends to the outside of the wall. A contact block 906 is fixedly connected to the bottom end of the connecting rod 905.

[0060] Furthermore, a fixed bracket 907 is fixedly connected to the support guide rod 401, and a fixed shell 908 is fixedly connected to the fixed bracket 907. A double-sloped contact slider 909 is slidably connected in the inner cavity of the fixed shell 908, which is used to form a sloped contact engagement with the contact block 906 during the lifting process.

[0061] One end of a spring 910 is fixedly connected to one side of the double-sloped contact slider 909, and the other end of the spring 910 is fixedly connected to the fixed shell 908.

[0062] Furthermore, an output hose 911 and an input pipe 912 are fixedly connected to the upper side of the inner cavity of the fixed cylinder 903. One end of the output hose 911 extends into the inner cavity of the positioning post 804 and is connected to the bend 901. The input pipe 912 is used to connect to an external liquid supply source, preferably a volatile low-viscosity assembly lubricating oil.

[0063] Both the output hose 911 and the input hose 912 are equipped with check valves to prevent liquid backflow and maintain positive pressure in the pipeline.

[0064] With the above technical solution, when the pressing assembly drive mechanism 4 drives the lifting slider 402 to press down and start the assembly operation, the contact block 906 moves down and first comes into contact with the downward contact slope of the double slope contact slider 909. As the downward stroke increases, the contact block 906 presses the double-sloping contact slider 909 to move laterally against the resistance of the spring 910. At the same time, the connecting rod 905 drives the piston 904 to move upward relative to the inner cavity of the fixed cylinder 903, pumping the lubricating oil stored in the cavity to the inner cavity of the positioning column 804 through the output hose 911, and spraying it out from the nozzle 902 through the bend pipe 901, covering the outer circumferential surface of the planetary carrier 103.

[0065] After the preset spray stroke is completed, the double-sloped contact slider 909 retracts under the action of the spring 910 when it moves laterally to the limit position. This causes the double-sloped contact slider 909 to disengage from the contact block 906, thereby releasing the vertical constraint on the contact block 906. This allows the planetary carrier clamping mechanism 8 to continue moving down to the pressing station, avoiding interference of the spray mechanism with the pressing stroke and ensuring that the lubrication operation is completed in the initial stage of pressing.

[0066] When the pressing is completed and the lifting slider 402 moves up and resets, the contact block 906 moves up accordingly and contacts the reset guide slope of the double-sloped contact slider 909 again during the reset process, forcing the double-sloped contact slider 909 to move laterally again, thereby ensuring that the contact block 906 can smoothly return to the initial position. At the same time, the piston 904 moves down and draws in lubricating oil from the external liquid supply source through the input pipe 912 to complete the replenishment action of the next working cycle.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
