Description

Technical Field

[0001] This utility model relates to the technical field of crankshaft processing equipment mechanisms, specifically to a power gearbox. Background Technology

[0002] The drive and internal transmission mechanisms of the cutting power housing in crankshaft milling machine tools are key components of cutting machine equipment. In gear-driven power housings (such as reduction gearboxes, transmissions, and engine gear chambers), friction pairs such as gear meshing and bearing operation inevitably generate wear particles, among which ferromagnetic particles (iron chips) are one of the most significant wear products. These impurities, suspended or deposited in the lubricating oil, exacerbate equipment wear, clog oil passages, reduce lubrication efficiency, and in severe cases, lead to equipment failure.

[0003] To ensure normal equipment operation and extend service life, modern power gearboxes generally employ filtration structures to filter lubricating oil and handle iron filings, filtering all lubricating oil through a single flow path. In lubricating oil circulation systems, traditional designs often rely on gravity settling or simple filter screen interception, which easily leads to the deposition of impurities such as iron filings at the bottom of the gearbox (the suction force of the single flow path suction end is limited, and some iron filings will deposit at the bottom of the gearbox) or causes filter screen clogging (iron filings and impurities are all concentrated and filtered through the filter screen), making them inconvenient to handle. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a power chassis that solves the technical problem that traditional designs in the prior art rely on gravity settling or simple filter interception, which easily leads to the deposition of impurities such as iron filings at the bottom of the chassis or filter blockage, making them inconvenient to handle.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a power chassis, comprising:

[0007] Box;

[0008] A lid, which is detachably mounted on the top of the enclosure; and

[0009] The lubricating oil circulation structure includes a sink box, a filter assembly, and a circulation pipeline. The sink box is connected to the bottom side of the housing. The inner bottom wall of the housing is inclined towards the sink box, and the inner bottom wall of the sink box is lower than the inner bottom wall of the housing. The filter assembly is inserted into the inner side of the sink box and has an inlet end and an outlet end. The two ends of the circulation pipeline are respectively connected to the outlet end of the filter assembly and the housing cover, for pumping the lubricating oil filtered by the filter assembly from bottom to top and circulating it in the housing. The filter assembly has a magnetic suction end and a filter end arranged sequentially along the pumping direction.

[0010] In some embodiments, the filtration assembly includes a filter basket, a guide cylinder, a magnetic plate assembly, and a filter screen. The filter basket is inserted into the inner side of the sink box and connected to the guide cylinder via a bracket. The filter screen is inserted into the top of the guide cylinder for filtering impurities. The magnetic plate assembly is inserted into the inner side of the guide cylinder for magnetically absorbing and collecting iron filings.

[0011] In some embodiments, the filter assembly further includes a cover detachably connected to the top of the sink box and having an opening for inserting a guide tube, wherein the circulation pipeline is detachably connected to the top of the guide tube.

[0012] In some embodiments, the magnetic plate assembly includes a first magnetic plate and a second magnetic plate. The guide cylinder has an installation port, the first magnetic plate is inserted into the installation port, and a plurality of second magnetic plates are disposed on the side of the first magnetic plate near the guide cylinder. The other side of the second magnetic plates extends outward to the other side of the first magnetic plate.

[0013] In some embodiments, the mounting port is located at the bottom of the guide cylinder, and the bracket is provided with an annular seat, which is sleeved on the outside of the first magnetic plate and detachably connected to the guide cylinder.

[0014] In some embodiments, the outer side of the first magnetic plate is provided with a sealing strip that abuts against the inner wall of the mounting port.

[0015] In some embodiments, the circulation pipeline includes a first connecting pipeline, a pump body, and a second connecting pipeline. The bottom end of the first connecting pipeline is provided with a connecting flange, which is detachably connected to the top end of the guide cylinder. The other end of the first connecting pipeline is detachably connected to the pump body.

[0016] In some embodiments, the first connecting pipe is L-shaped, and the lateral end of the L-shape of the first connecting pipe extends to the outside of the sunken box.

[0017] In some embodiments, the second connecting pipe is connected to a plurality of fuel injectors.

[0018] In some embodiments, an annular cover is provided on the outer side of the connecting flange, and a sealing gasket is provided at the bottom of the annular cover.

[0019] Compared with the prior art, the power housing provided by this utility model allows the lubricating oil to flow downwards at an angle through the bottom slope of the housing. Under the flow of the pumped circulating oil, gravity and flow inertia guide impurities such as iron filings to migrate towards the filter structure, improving the settling efficiency and preventing iron filings from depositing at the bottom of the housing. The filter assembly first uses magnetic attraction for filtration, which separates the majority of iron filings. Then, the filter end filters out any missed iron filings and non-iron filings, achieving a multi-stage filtration effect, reducing the amount of impurities that need to be filtered at the filter end, and reducing the probability of possible clogging.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To address the technical problem that traditional designs often rely on gravity settling or simple filter interception, leading to the accumulation of impurities such as iron filings at the bottom of the chassis or filter clogging, which is inconvenient to handle, this utility model provides a power chassis that utilizes gravity and flow inertia to guide impurities such as iron filings to migrate towards the filtration structure, improving settling efficiency; a magnetic plate adsorbs magnetic particles, while the filter intercepts non-magnetic impurities, achieving multi-stage high-efficiency filtration; precise spraying covers the gear meshing area; and a multi-layered, synergistic filtration mechanism is constructed to improve the filtration reliability and stability of the system during long-term operation, reduce maintenance frequency, and ensure smooth circulation of lubricating oil.

[0029] It should be noted that the power housing described in this utility model is used for, but not limited to, power housings for crankshaft milling machine tools. For ease of explanation, this utility model only uses the power housing applied to a power housing for crankshaft milling machine tools as an example for explanation. The principle of the power housing applied to other types of equipment is essentially the same as that applied to a power housing for crankshaft milling machine tools, and will not be elaborated here.

[0030] Please see Figure 1-3This utility model provides a power gearbox, which includes a gearbox body 1, a gearbox cover 2, and a lubricating oil circulation structure 3. The gearbox cover 2 is detachably installed on the top of the gearbox body 1. The lubricating oil circulation structure 3 includes a sink box 31, a filter assembly 32, and a circulation pipeline 33. The sink box 31 is connected to the bottom side of the gearbox body 1. The inner bottom wall of the gearbox body 1 is inclined towards the sink box 31, forming a plane that guides the deposited iron filings to slide towards the sink box 31. This causes some iron filings that are difficult to remove to be deposited in the sink box 31, thereby reducing the iron filings deposited at the bottom of the gearbox body 1 and moving them away from the gear working area. They are deposited in the sink box 31, which is located outside the gear working area. The inner bottom wall of the sink box 31 is lower than the inner bottom wall of the gearbox body 1, which can effectively accommodate the deposited iron filings and provide a settling height. The filter assembly 32 is inserted into the inner side of the sink box 31 and has an inlet end 32a and an outlet end 32b. The two ends of the circulation pipe 33 are respectively connected to the outlet end 32b of the filter assembly 32 and the box cover 2, for pumping the lubricating oil filtered by the filter assembly 32 from bottom to top and circulating it in the box body 1. The filter assembly 32 has a magnetic suction end and a filter end arranged sequentially along the pumping direction. The magnetic suction end magnetically separates iron filings in the oil, and the filter end filters and intercepts iron filings and other impurity particles that are not attracted by the magnetic suction end, forming a synergistic filtration effect. Furthermore, the magnetic suction end can reduce the filtration burden of the filter end, reduce its filtration volume, thereby extending its service life, delaying clogging time, and reducing the probability of clogging. The outlet end 32b is detachably connected to the circulation pipeline 33. After disassembly, the filter component 32 can be processed separately. Furthermore, the oil level is lower than the top height of the sink box 31, so that when the top of the sink box 31 is opened and the filter component 32 is removed, the leakage of the internal oil will not be affected.

[0031] In one embodiment, please refer to Figure 1 and Figure 2 To facilitate the cleaning of iron filings deposited in the sink box 31 and the removal and cleaning of the filter assembly 32, the filter assembly 32 includes a filter basket 321, a guide cylinder 322, a magnetic plate assembly 323, and a filter screen 324. The filter basket 321 is inserted into the inner side of the sink box 31 and is connected to the guide cylinder 322 via a bracket 321a. The filter basket 321 serves as a storage basket at the bottom of the sink box 31, allowing iron filings to deposit inside. When the entire filter assembly 32 is removed, the filter basket 321 can be pulled out. Oil permeates downwards through the mesh structure of the filter basket 321, while the deposited iron filings remain inside the filter basket 321, facilitating the cleaning of the iron filings deposited in the sink box 31.

[0032] Furthermore, the filter screen 324 is inserted into the top of the guide cylinder 322 to filter impurities, and the magnetic plate assembly 323 is inserted into the inner side of the guide cylinder 322 to magnetically absorb and collect iron filings. The suction direction is from bottom to top. The guide cylinder 322 is inserted into the oil. During suction, the oil passes through the guide cylinder 322 and is first magnetically attracted to the iron filings by the magnetic plate assembly 323 inside the guide cylinder 322. It continues upward and is then filtered by the filter screen 324.

[0033] For further details, please refer to Figure 1 , Figure 2 and Figure 3 To facilitate providing a sufficiently large opening at the top of the sink box 31 and for closing, the filter assembly 32 also includes a cover 325. The cover 325 is detachably connected to the top of the sink box 31 and has a port 326 for inserting the guide cylinder 322. The circulation pipe 33 is detachably connected to the top of the guide cylinder 322. That is, the guide cylinder 322 is first inserted into the port 326 from top to bottom, and the outer side of the top of the guide cylinder 322 is also provided with a limiting edge to limit its insertion into the cover 325. Then, the magnetic plate assembly 323 and other structures are installed. Finally, after the cover 325 is placed on the top of the sink box 31, the circulation pipe 33 is installed, and the guide cylinder 322 is connected to the circulation pipe 33.

[0034] Furthermore, to provide a sufficiently large magnetic attraction area and to also magnetically attract iron filings suspended on the surface, the magnetic plate assembly 323 includes a first magnetic plate 3231 and a second magnetic plate 3232. The guide cylinder 322 has an installation port 3221. The first magnetic plate 3231 is inserted into the installation port 3221. Several second magnetic plates 3232 are disposed on the side of the first magnetic plate 3231 near the guide cylinder 322. The other side of the second magnetic plate 3232 extends outward to the other side of the first magnetic plate 3231. The extension of the second magnetic plate 3232 to the other side of the first magnetic plate 3231 can magnetically attract iron filings suspended above the oil on the outside. The combination of the first magnetic plate 3231 and the second magnetic plate 3232 can provide a larger magnetic attraction area. In addition, the second magnetic plate 3232 divides the interior of the guide cylinder 322 to allow the oil to pass through, resulting in a better magnetic attraction effect and reducing the probability of missing iron filings.

[0035] Furthermore, to facilitate the installation and removal of the magnetic plate assembly 323, the mounting port 3221 is located at the bottom of the guide cylinder 322. The bracket 321a is provided with an annular seat 321b, which is fitted onto the outer side of the first magnetic plate 3231 and detachably connected to the guide cylinder 322. Specifically, the annular seat 321b has an annular groove that fits between the bottom of the guide cylinder 322 and the first magnetic plate 3231. The inner wall of the annular groove has an internal thread, and the guide cylinder 322 has an external thread, allowing the annular seat 321b to be threadedly connected to the guide cylinder 322, facilitating installation and removal. That is, first, the first magnetic plate 3231 is inserted into the mounting port 3221, limiting its top, front, and rear sides. Then, the annular seat 321b is installed to limit the bottom of the first magnetic plate 3231. Conversely, removing the annular seat 321b allows the first magnetic plate 3231 to be removed downwards.

[0036] Furthermore, in order to provide a seal, the outer side of the first magnetic plate 3231 is provided with a sealing strip that abuts against the inner wall of the mounting port 3221. The sealing strip also abuts against the annular groove on the annular seat 321b to provide a seal on the outer periphery of the first magnetic plate 3231.

[0037] In one embodiment, please refer to Figure 1 In order to provide oil circulation, the circulation pipeline 33 includes a first connecting pipeline 331, a pump body 332 and a second connecting pipeline 333. The bottom end of the first connecting pipeline 331 is provided with a connecting flange 334, which is detachably connected to the top end of the guide cylinder 322 through the connecting flange 334. The other end of the first connecting pipeline 331 is detachably connected to the pump body 332, and the pump body 332 pumps the oil for circulation.

[0038] The connecting flange 334 is provided with an annular cover 336 on its outer side. The bottom of the annular cover 336 is provided with a sealing gasket. The guide cylinder 322 is inserted into the top of the cover body 325. Specifically, the bolts on the connecting flange 334 pass through the outer periphery of the filter screen 324 and the limiting edge of the guide cylinder 322, and are threadedly connected to the cover body 325. Pressing down forms a fastening, limiting and pressing the filter screen 324 inserted into the top of the guide cylinder 322 to the top of the guide cylinder 322, and pressing the guide cylinder 322 to the top of the cover body 325.

[0039] Understandably, the connecting flange 334 can be directly connected to the guide cylinder 322, or it can be connected to the cover 325 and pressed onto the top of the guide cylinder 322 in a movable connection manner, so that the first connecting pipe 331 can be connected and connected to the guide cylinder 322.

[0040] Furthermore, in order to lubricate the gear meshing position with oil, the second connecting pipe 333 is connected to several oil nozzles 335, so that targeted lubrication can be performed.

[0041] Furthermore, the first connecting pipe 331 is L-shaped, and the lateral end of the L-shape of the first connecting pipe 331 extends to the outside of the sink box 31. Depending on the position of the pump body 332, an extension pipe may also be provided to connect the pump body 332 to the L-shaped first connecting pipe 331, such as... Figure 2 As shown, at this point, the first connecting pipe 331 in the L-shape can be disassembled, and the entire filter assembly 32 can be pulled upwards, which is convenient and quick.

[0042] Understandably, the filter specifications of filter screen 324 and filter basket 321 are selected according to the diameter of the particles to be filtered, so as to intercept and filter the particles that need to be filtered.

[0043] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: In use, the oil enters the sink box 31, where the iron filings are first magnetically separated by the magnetic plate assembly 323, then filtered a second time by the filter screen 324, and then transported to the oil injector 335 through the circulation pipeline 33 to lubricate the gear meshing parts, forming a circulating oil circuit within the housing 1; when it is necessary to clean the iron filings and impurities, the L-shaped part of the first connecting pipeline 331 can be directly disassembled, allowing the entire filter assembly 32 to be lifted and pulled out of the sink box 31; during the extraction process, The entire filter basket 321 can be pulled out, which can remove the deposited iron filings and settled impurities, and can also catch impurities that fall from the filter screen 324. After being pulled out, the annular seat 321b can be disassembled to separate the filter basket 321 from the guide cylinder 322. Then, the magnetic plate assembly 323 can be removed for separate cleaning. After removing the magnetic plate assembly 323, the connecting flange 334 can be disassembled to remove the filter screen 324 for separate cleaning of the filter screen 324 and the guide cylinder 322.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
