Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a flange assembly with a dustproof structure. Background Technology

[0002] Flange assemblies, also known as flange assemblies, are key components in mechanical transmission systems that connect shafts to rotating parts such as wheels, gears, and pulleys. Their basic functions are to provide reliable connections, transmit torque, and bear loads.

[0003] A search revealed a military SVU gearbox flange assembly with publication number CN212028365U, comprising a flange base, a flange cylinder connected by a spline inside the draft tube, a fixing ring welded to the top of the outer wall of the flange cylinder, a dust cover body located above the top of the flange cylinder, an installation groove on the top of the fixing ring body, and raised strip blocks evenly distributed on the top surface of the fixing ring body. Rubber skin is adhered to the outer surface of the dust cover body, and a circular wall extending downwards from the bottom side of the dust cover body to mate with the installation groove is provided. A push-in ring block is welded to the bottom of the circular wall. Sealing rings are fixed to the bottom of both the outer and inner side walls of the rubber skin, and grooves are provided at the bottom of the sealing rings to mate with the strip blocks. This invention, by setting an elastic limiting device, ensures a secure installation of the dust cover body and the fixing ring body, preventing the push-in ring block from easily detaching from the installation groove. It has a long service life, is easy to install, does not require welding for fixation, and saves production costs.

[0004] During use, the continuous vibration of the vehicle during driving may cause the spring to loosen, resulting in a decrease in clamping force, the dust cover to fall off, and affecting the dustproof effect. The lifespan of the spring and rubber ring is short, the frequency of inspection and maintenance is high, and the practicality is low. Utility Model Content

[0005] In response to the technical problems in existing patents, such as the continuous vibration of the vehicle during use causing the spring to loosen, resulting in a decrease in clamping force, the dust cover to fall off, and affecting the dustproof effect, as well as the low service life of the spring and rubber ring, the high frequency of inspection and maintenance, and the low practicality, this utility model provides a flange assembly with a dustproof structure.

[0006] The technical solution adopted in this utility model is: a flange assembly with a dustproof structure, comprising: A flange structure, the flange structure including a flange base, a draft tube mounted on the top of the flange base, and a flange cylinder mounted on the top of the draft tube; A dustproof assembly is installed on the outside of the flange cylinder and is used to prevent dust from entering the flange structure. The dustproof assembly includes a positioning seat fixedly welded to the outer wall of the flange cylinder, a disassembly and assembly structure installed inside the positioning seat, a dustproof plate installed on the top of the positioning seat, and a dustproof net installed on the dustproof plate.

[0007] Furthermore, the positioning seat has a positioning groove at the top, an adjustment groove at the bottom, a transmission cavity at the front of the adjustment groove, and a self-locking groove at the front of the transmission cavity. The disassembly and assembly structure includes an adjustment component installed inside the adjustment groove, a transmission component installed inside the transmission cavity, and a self-locking component installed inside the self-locking groove.

[0008] Furthermore, the adjusting component includes a bidirectional threaded rod rotatably mounted between the inner sidewalls of the adjusting groove, a first threaded ring and a second threaded ring threadedly engaged on the bidirectional threaded rod, and two threaded blocks respectively fixedly welded to the top of the first threaded ring and the second threaded ring.

[0009] Furthermore, the adjusting component also includes a limiting post fixedly welded to one side of the threaded block and a positioning block fixedly welded to the bottom of the dustproof plate. The positioning block cooperates with the positioning groove, and a limiting hole is provided on the positioning block. The limiting post cooperates with the limiting hole.

[0010] Furthermore, the transmission component includes a transmission gear fixedly sleeved on the outside of the bidirectional threaded rod shaft and a chain installed inside the transmission cavity, wherein the transmission gear meshes with the chain.

[0011] Furthermore, a control groove is provided at the top of the self-locking groove, and the self-locking component includes a worm gear fixedly sleeved on the outside of the bidirectional threaded rod shaft, a control head rotatably installed inside the control groove, and a worm with both ends rotatably installed between the bottom wall of the self-locking groove and the bottom of the control head. The worm gear meshes with the worm, and a cross groove is provided at the top of the control head.

[0012] The beneficial effects of this utility model are: By inserting a specific tool into the cross slot and rotating the control head, the worm gear is driven to rotate. The worm gear meshes with the worm wheel, causing a double-threaded rod to rotate. Through the transmission action of the transmission gear and chain, two double-threaded rods rotate simultaneously in the same direction. The rotation of the double-threaded rods drives the first and second threaded rings to move in opposite directions. The first and second threaded rings drive two threaded blocks to move in opposite directions. The threaded blocks drive the limit post to move, controlling the relative position of the limit post and the limit hole, and controlling the relative position of the positioning block and the positioning groove. This allows for the fixing or removal of the dustproof plate, facilitating cleaning or replacement of the dustproof net. The self-locking function of the worm gear effectively avoids loosening caused by vehicle vibration, improving the service life of the device and making it highly practical.

[0019] like Figure 1-4 As shown, the dustproof component 2 is installed on the outside of the flange cylinder 103. The dustproof component 2 is used to protect the flange structure 1 from dust.

[0020] The dustproof assembly 2 includes a positioning seat 201 fixedly welded to the outer wall of the flange cylinder 103, a disassembly and assembly structure 202 installed inside the positioning seat 201, a dustproof plate 203 installed on the top of the positioning seat 201, and a dustproof net 204 installed on the dustproof plate 203.

[0021] Furthermore, the dustproof component 2 includes a positioning seat 201 fixedly welded to the outer wall of the flange cylinder 103, a disassembly and assembly structure 202 installed inside the positioning seat 201, a dustproof plate 203 installed on the top of the positioning seat 201, and a dustproof net 204 installed on the dustproof plate 203.

[0022] Furthermore, the adjusting component 2021 also includes a limiting post 7 fixedly welded to one side of the threaded block 6 and a positioning block 8 fixedly welded to the bottom of the dustproof plate 203.
