Description

Technical Field

[0001] This utility model relates to the technical field of flywheel production, specifically to a flywheel gear ring tooth gap cleaning mechanism. Background Technology

[0002] As a core transmission component of the engine starting system, the cleanliness of the flywheel ring gear's tooth surface directly affects the starter's meshing reliability and the vehicle's NVH performance. Currently, after processes such as hobbing, chamfering, drilling, and induction hardening, cutting oil, metal shavings, oxide scale, or rust-preventive grease often remain in the tooth gaps of the ring gear. If not thoroughly cleaned, this can easily lead to starting gear grinding, abnormal noise, or even premature failure.

[0003] Existing cleaning methods mainly include manual wiping, ultrasonic cleaning, or fixed spraying. Manual methods are inefficient, inconsistent, and prone to scratching hardened tooth surfaces; while ultrasonic cleaning can penetrate micro-gaps, its ability to remove adhesive oil films is limited, and it is slow and costly; fixed spraying is difficult to cover the tooth root area, leaving many cleaning blind spots. More importantly, existing equipment generally lacks the ability to precisely position and conform to the tooth profile, failing to meet the stringent cleanliness requirements of high-end products such as dual-mass flywheels.

[0004] Therefore, there is an urgent need for a specialized cleaning mechanism that integrates self-centering clamping, intermittent indexing, contour cleaning, and automatic obstacle avoidance to achieve efficient, non-destructive, and fully automatic deep cleaning of tooth gaps.

[0006] A tooth gap cleaning mechanism for a flywheel gear ring includes: Cleaning pool; The cleaning mechanism, set in the cleaning pool, includes a cleaning box, a motor and a contour cleaning roller. The motor drives the contour cleaning roller to move up and down vertically in the cleaning box through a cam structure, so as to clean the tooth surfaces of each tooth on the gear ring in sequence. Multiple rotating mechanisms are evenly arranged circumferentially in the cleaning pool. Each rotating mechanism includes a dual-axis cylinder, a second motor, and a rotating wheel. The dual-axis cylinder drives the outer circumferential surface of the rotating wheel to abut against the inner circumferential surface of the gear ring, and the upper and lower rims of the rotating wheel contact the upper and lower end faces of the gear ring, respectively. The second motor drives the rotating wheel to rotate intermittently, thereby driving the gear ring to rotate intermittently synchronously.

[0010] Preferably, the top of the cleaning box is connected to a water inlet pipe, and the bottom of the cleaning pool is connected to a drain pipe.

[0011] Preferably, a friction sleeve is fitted on the outer circumferential surface of the rotating wheel.

[0013] Preferably, the two ends of the rotating shaft are respectively connected to gears through one-way bearings, and a pair of racks are symmetrically fixed on both sides of the cleaning box, the racks meshing with the corresponding gears.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 8 As shown, a tooth gap cleaning mechanism for a flywheel gear ring includes: Cleaning tank 10; The cleaning tank 10 serves as the base of the overall structure and a liquid container, used to hold cleaning fluid and integrate various functional modules, facilitating wet cleaning and centralized wastewater treatment.

[0029] The cleaning mechanism 20 is installed in the cleaning pool 10 and includes a cleaning box 201, a motor 205, and a contour cleaning roller 208. The motor 205 drives the contour cleaning roller 208 to move vertically up and down in the cleaning box 201 through a cam structure to clean the tooth surfaces of each tooth on the toothed ring 50 in sequence. The cam 206 drives the contour cleaning roller 208 to move vertically back and forth, realizing tooth-by-tooth point cleaning and improving cleaning coverage and consistency.

[0030] Multiple rotating mechanisms 30 are evenly arranged circumferentially within the cleaning tank 10. Each rotating mechanism 30 includes a dual-axis cylinder 301, a second motor 307, and a rotating wheel 308. The dual-axis cylinder 301 drives the outer circumferential surface of the rotating wheel 308 to abut against the inner circumferential surface of the gear ring 50, and the upper and lower rims of the rotating wheel 308 respectively contact the upper and lower end faces of the gear ring 50. The second motor 307 drives the rotating wheel 308 to rotate intermittently, thereby driving the gear ring 50 to rotate intermittently synchronously. The rotating wheel 308 achieves self-centering clamping of the gear ring 50 without clamps through three-sided contact (inner circle + upper and lower end faces), preventing deflection or slippage. The intermittent rotation, in conjunction with the action of the contour cleaning roller 208, ensures that each tooth can be accurately aligned to the cleaning station, improving the automation cycle time and positioning accuracy.

[0031] Multiple alignment mechanisms 40 are evenly arranged circumferentially within the cleaning tank 10. Each alignment mechanism 40 includes a placement plate 404, the upper surface of which is flush with the lower rim of the rotating wheel 308, for supporting and positioning the gear ring 50. The placement plate 404 provides an initial support reference and is coplanar with the lower rim of the rotating wheel 308, ensuring that the gear ring 50 is placed smoothly without suspension, avoiding deformation or misalignment due to gravity, and improving clamping reliability and ease of operation.

[0032] In this embodiment, a pair of guide posts 202 are vertically fixed inside the cleaning box 201. A C-shaped movable frame 203 is slidably connected to the guide posts 202. A compression spring 204 is sleeved on each guide post 202. The motor 205 is installed on the upper part of the cleaning box 201, and a cam 206 is fixedly connected to its output end. The contour surface of the cam 206 abuts against the upper side of the movable frame 203. The contour cleaning roller 208 is rotatably connected to the movable frame 203 through a rotating shaft 207. A plurality of contour cleaning grooves 208a are spaced apart on the outer circumference of the contour cleaning roller 208. Each contour cleaning groove 208a matches the tooth surface shape of the corresponding tooth on the tooth ring 50. The guide post 202 and the compression spring 204 form an elastic guiding system, which enables the contour cleaning roller 208 to have a buffering capacity when it contacts the tooth surface, and adapts to the manufacturing tolerance of the tooth ring 50; the contour cleaning groove 208a fits precisely with the tooth shape, and can penetrate deep into the tooth root to remove oil and metal shavings, significantly improving the cleaning quality.

[0033] In this embodiment, the dual-axis cylinder 301 is horizontally mounted at the bottom of the cleaning tank 10. Its piston rod extends toward the center of the gear ring 50 and is connected to a movable plate 302. Multiple movable pins 303 are slidably connected to the upper part of the movable plate 302. The outer ends of each movable pin 303 are connected to an L-shaped movable plate 305. A compression spring 306 is fitted onto each movable pin 303. A second motor 307 is mounted on the bottom of the movable plate 305. The rotating wheel 308 is coaxially and fixedly connected to the output end of the second motor 307. The dual-axis cylinder 301 provides a stable radial clamping force. The movable pins 303 and the compression spring 306 constitute a flexible floating mechanism, allowing the rotating wheel 308 to adapt to gear rings 50 of different diameters.

[0034] In this embodiment, a pair of fixed tubes 401 are symmetrically fixed on the left and right sides of the dual-axis cylinder 301 in the cleaning pool 10. A wedge-shaped movable block 402 is slidably fitted inside the fixed tube 401. A compression spring 303 is connected between the bottom of the movable block 402 and the bottom end of the fixed tube 401. A pair of connecting plates 405 are vertically fixed to the lower side of the placement plate 404. The connecting plates 405 are respectively fixedly connected to the corresponding movable blocks 402. A pair of moving rods 304 are vertically fixed to the middle of the moving plate 302. When the dual-axis cylinder 301 pushes the moving plate 302, the moving rods 304 press down on the movable blocks 402 with a lag, so that the placement plate 404 automatically sinks to avoid the toothed ring 50 on the rotating wheel 308, avoiding interference. After being released, the compression spring 303 returns to its original position, and the placement plate 404 rises back to the support position, realizing the "clamping-avoidance-reset" linkage. No additional driving components are required, and the structure is ingenious and efficient.

[0035] In this embodiment, the top of the cleaning box 201 is connected to a water inlet pipe 212, and the bottom of the cleaning pool 10 is connected to a drain pipe 11. The water inlet pipe 212 is used to introduce cleaning fluid into the cleaning box 201; the drain pipe 11 is used to discharge the cleaning fluid after cleaning to the outside of the cleaning pool 10.

[0036] In this embodiment, a friction sleeve 309 is fitted onto the outer circumferential surface of the rotating wheel 308. The friction sleeve 309 is made of a high-friction coefficient elastic material (such as polyurethane) to enhance the friction with the inner wall of the gear ring 50, prevent slippage, ensure reliable rotational transmission, and protect the inner surface of the gear ring 50 from scratches.

[0037] In this embodiment, the placement plate 404 is provided with a plurality of drainage holes 404a evenly distributed on it. The drainage holes 404a facilitate the rapid drainage of cleaning fluid and prevent water accumulation from affecting subsequent operations.

[0038] In this embodiment, the two ends of the rotating shaft 207 are respectively connected to gears 210 through one-way bearings 209, and a pair of racks 211 are symmetrically fixed on both sides of the cleaning box 201, and the racks 211 mesh with the corresponding gears 210.

[0039] The working process of this flywheel gear ring tooth gap cleaning mechanism is as follows: During operation, the gear ring 50 to be cleaned is placed on the placement plate 404 of the multiple alignment mechanisms 40. Since the upper surface of the placement plate 404 is at the same level as the lower rim of the rotating wheel 308, it can be ensured that the gear ring 50 is supported stably and horizontally.

[0040] Subsequently, the dual-axis cylinder 301 actuates, its piston rod retracts inward, driving the moving plate 302 and the connected L-shaped movable plate 305 to move synchronously, so that the outer circumferential surface of the rotating wheel 308 is pressed against the inner circumferential surface of the gear ring 50, while its upper and lower rims press against the upper and lower end faces of the gear ring 50 respectively, achieving reliable clamping. During this process, the moving rod 304 in the middle of the moving plate 302 presses down the wedge-shaped movable block 402 with a lag, compressing the compression spring 3 403, causing the placement plate 404 to sink as a whole, thereby avoiding rotation space and preventing it from interfering with the subsequently rotating gear ring 50.

[0041] Next, motor 207 starts, driving the rotating wheel 308 to precisely and intermittently rotate the gear ring 50, aligning the first tooth position with the cleaning station. At this time, motor 1 205 starts running, driving cam 206 to rotate, pushing C-shaped movable frame 203 to move downward along guide post 202, causing the contour cleaning roller 208 to descend, and precisely embedding the contour cleaning groove 208a on its surface into the tooth surface contour of the corresponding tooth.

[0042] During descent, the gears 210 at both ends of the contour cleaning roller 208 mesh with the racks 211 on both sides of the cleaning box 201, driving the contour cleaning roller 208 to rotate around its own axis via the one-way bearing 209, achieving simultaneous contact and brushing, significantly improving the cleaning effect between the teeth. When the contour cleaning roller 208 reaches its lowest position, it is completely immersed in the cleaning fluid in the cleaning box 201, completing self-cleaning and preparing for the next tooth position operation.

[0043] After cleaning a single tooth, the contour cleaning roller 208 returns to its original position under the action of the compression spring 204, and the toothed ring 50 rotates intermittently by one tooth pitch again, entering the next cleaning cycle. This process is repeated until all tooth gaps are cleaned.

[0044] The entire process is fully automated and requires no manual intervention. It combines high efficiency, high consistency, and high cleanliness, effectively meeting the stringent process requirements for tooth surface cleanliness of flywheel gear rings before assembly.

[0045] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
