Description

Technical Field

[0001] This utility model relates to the field of lubrication system technology, specifically to an oil mist distribution device for an oil mist lubrication system. Background Technology

[0002] As the core lubrication guarantee unit for various mechanical equipment (such as machine tools, gearboxes, hybrid vehicle powertrains, etc.), the oil mist lubrication system directly affects the operational reliability and service life of the equipment by ensuring the stability of the oil mist distribution device and its adaptability to operating conditions.

[0003] Currently, existing oil mist distribution devices are mainly divided into two categories: single-chamber and dual-chamber systems. However, both have significant technical defects in practical applications, making it difficult to meet the lubrication needs of multiple operating conditions. Single-chamber oil mist distribution devices, with their simple structure and oil output through a single working chamber, not only have limited flow rates, making them unsuitable for the high-flow lubrication demands of a single-drive unit operating at high power, but also pose a high risk of equipment downtime if piston jamming or drive failure occurs. Furthermore, their fixed supply mode, lacking adjustment options, fails to meet the diverse lubrication needs of multiple drive units.

[0004] Although the dual-chamber oil mist distribution device has two working chambers, it can only achieve independent liquid supply to both chambers. It lacks a structural design and control mechanism for cross-chamber coordinated liquid supply and cannot switch between independent and cross-supply modes. When the equipment is in a condition where one set of drive units is operating at high power and the other set of drive units is in standby, the two chambers still maintain independent liquid supply. On the one hand, this leads to oil waste on the standby side, and on the other hand, the working side relies on liquid supply from only one chamber, resulting in insufficient liquid flow. This makes it difficult to ensure lubrication reliability under high-power operation and easily causes wear of the drive units. Therefore, we propose an oil mist distribution device for oil mist lubrication systems. Utility Model Content

[0005] The purpose of this invention is to provide an oil mist distribution device for an oil mist lubrication system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil mist distribution device for an oil mist lubrication system, comprising a housing and an input component. The housing has an internal partition plate that divides the interior into two independent working chambers. Each of the two working chambers is equipped with a drive component for liquid supply. Both working chambers are connected to an output interface, and each output interface is equipped with an output check valve. Each output interface is connected to an output pipe at its end. Each set of output pipes is equipped with an adjustable cross-supply component, which is connected to the non-connected working chambers.

[0007] Preferably, the adjustable cross-feed assembly includes a flow guide interface, the upper end of which is connected to the inside of the output pipe, and the lower end of which is connected to the inside of the non-connected working chamber via a one-way pipe. An electrically controlled valve assembly is installed inside the flow guide interface.

[0008] Preferably, a flow-changing check valve is installed at the end of the one-way pipe that communicates with the working chamber.

[0009] Preferably, the electronically controlled valve assembly includes a trapping channel communicating with the interior of the flow guide interface, and both ends of the trapping channel are closed.

[0010] Preferably, a seal for sealing the flow guide interface is movably installed inside the interception channel, and an extension for accommodating the seal is provided at one end of the interception channel.

[0011] Preferably, a telescopic motor is fixedly installed on the outside of the interception channel, and a drive rod is fixedly installed on the output end of the telescopic motor. One end of the drive rod slides into the inside of the interception channel and is fixedly connected to the seal.

[0012] Preferably, a shut-off valve is installed on the upper side of the output check valve at the output interface.

[0013] Preferably, the drive assembly includes a piston disposed inside each working chamber and a connecting rod, the two ends of which are fixedly connected to the two pistons respectively, and the connecting rod is slidably mounted on the partition plate and sealed with the partition plate.

[0014] Preferably, sealing caps for sealing the working chamber are fixedly installed at both ends of the outer shell, and the sealing caps are provided with drive pipes for driving the reciprocating flow of the driving fluid, and the drive pipes are connected to a liquid supply system.

[0015] Preferably, the input component includes an input pipe, one end of which is connected to an oil storage container, and the other end of which is connected to two working chambers through an input interface, with an input one-way valve installed in each input interface.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves seamless switching between independent or cross-supply by coordinating the control of the shut-off valve and the electronically controlled valve assembly. When the single-group drive is running at high power, the two working chambers work together to supply liquid and improve the lubrication effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, an oil mist distribution device for an oil mist lubrication system includes a housing 1 and an input component 8. The housing 1 has a partition plate 2 inside, which divides the interior of the housing 1 into two independent working chambers 3. The two working chambers 3 are equipped with a drive component 4 for liquid supply. Both working chambers 3 are connected to an output interface 5. Each output interface 5 is equipped with an output check valve 51. The ends of both output interfaces 5 are connected to an output pipe 6. Each set of output pipes 6 is equipped with an adjustable cross-liquid supply component 7, which is connected to the non-connected working chambers 3.

[0025] In a normal independent fluid supply scenario: the two working chambers 3 each independently complete the oil output, ensuring the system's basic lubrication needs. At this time, the electronically controlled valve assemblies 72 of the two sets of adjustable cross-supply components 7 are all in the closed state to prevent oil cross-flow between the two chambers; the shut-off valves of the output interface 5 are all open, and the two oil streams are delivered to the target lubrication points through the corresponding output pipes 6, realizing dual-path independent and stable fluid supply, which is suitable for the system's normal operating conditions.

[0026] Cross-lubricant supply scenario (adapted to hybrid system electric drive and engine operation scenarios): When the hybrid system is in a condition where one set of drives is operating at high power and the other set of drives is in standby mode, the device can achieve precise allocation of lubrication resources through cross-lubricant supply. The specific logic is as follows: the shut-off valve of the output interface 5 connected to the standby drive and the corresponding electronically controlled valve assembly 72 are closed to stop the supply of lubricant to the standby system and avoid oil waste; at the same time, the electronically controlled valve assembly 72 connected to the working drive is activated (as the core control unit of cross-lubricant supply), and the telescopic motor 724 is activated after receiving the control signal, which drives the seal 72 through the drive rod 723. 2. Move along the axial direction of the interception channel 721. When the seal 722 disengages from the flow guide interface 71, the flow guide interface 71 is in the conducting state. At this time, the working chamber 3 in the standby state can be synchronously supplied with liquid to the output pipe 6 in the working state through the one-way pipe 73, so that the two sets of working chambers 3 can work together to supply liquid to the high-power driving system, which greatly improves the lubrication flow rate and lubrication reliability of the system. In addition, by controlling the start and stop and stroke of the telescopic motor 724, the opening / closing and the degree of opening of the flow guide interface 71 can be precisely controlled, thereby realizing the start and stop control of cross-supply and the adjustment of the supply flow rate to adapt to the lubrication supply needs under different working conditions.

[0027] The seamless switching between independent or cross-supply can be achieved through the coordinated control of the shut-off valve and the electronically controlled valve assembly 72. When the single-group drive is running at high power, the two working chambers 3 work together to supply liquid to improve the lubrication effect. When both groups are running, the two chambers independently supply liquid to ensure their respective lubrication needs, making it highly adaptable.

[0028] In this embodiment, the adjustable cross-feed assembly 7 includes a flow guide interface 71. The upper end of the flow guide interface 71 is connected to the inside of the output pipe 6, and the lower end of the flow guide interface 71 is connected to the inside of the non-connected working chamber 3 through a one-way pipe 73. An electrically controlled valve assembly 72 is installed inside the flow guide interface 71.

[0029] The flow guide interface 71 is a key connecting component for cross-supply. Its upper end is connected to the inside of the output pipe 6, and its lower end is connected to another working chamber 3 through the one-way pipe 73, forming a cross-chamber supply passage of the output interface 5, the flow guide interface 71, the one-way pipe 73 and the other working chamber 3, providing a physical channel for the cross-mixing of oil in the two chambers. The one-way pipe 73 is used to connect the flow guide interface 71 and the working chamber 3. Its length and direction are adapted to the overall layout of the device to ensure smooth flow of oil during cross-supply and avoid oil stagnation or pressure loss. The electronically controlled valve assembly 72 serves as the control unit of the cross-supply passage, realizing the automatic opening and closing of the supply passage and flow regulation, ensuring the accuracy and reliability of cross-supply, and preventing cross-flow of oil between the two chambers when there is no demand.

[0030] In this embodiment, a flow-changing one-way valve 74 is installed at the end of the one-way pipe 73 that is connected to the working chamber 3.

[0031] The one-way valve 74 is used to achieve one-way flow of oil, allowing only the oil in the working chamber 3 to flow into the one-way pipe 73.

[0032] In this embodiment, the electronically controlled valve assembly 72 includes a trapping channel 721 that communicates with the interior of the flow guide interface 71. The two ends of the trapping channel 721 are closed, and a seal 722 for sealing the flow guide interface 71 is movably installed inside the trapping channel 721. One end of the trapping channel 721 is provided with an extension for accommodating the seal 722.

[0033] In this embodiment, a telescopic motor 724 is fixedly installed on the outside of the interception channel 721, and a drive rod 723 is fixedly installed on the output end of the telescopic motor 724. One end of the drive rod 723 slides into the inside of the interception channel 721 and is fixedly connected to the seal 722.

[0034] The hollow structure inside the interception channel 721 is adapted to the axial movement of the seal 722, providing space for the seal 722 to switch between sealed and open states. At the same time, through the connection design with the flow guide interface 71, the seal 722 can be precisely embedded into the flow guide interface 71 to close the channel, or detached from the flow guide interface 71 to open the channel.

[0035] In this embodiment, a shut-off valve is installed on the upper side of the output check valve 51 at the output interface 5.

[0036] The shut-off valve is used to control the on / off state of output interface 5, adapting to various liquid supply needs. In the normal dual-chamber independent liquid supply scenario, the shut-off valve remains open to ensure that the oil flows smoothly through output interface 5 into output pipe 6; in the cross-supply scenario, the shut-off valve connected to the standby driver can be closed to stop the liquid supply to the standby system and avoid oil waste.

[0037] In this embodiment, the drive assembly 4 includes a piston 41 disposed inside each working chamber 3 and a connecting rod 42. The two ends of the connecting rod 42 are fixedly connected to the two pistons 41 respectively. The connecting rod 42 is slidably mounted on the partition plate 2 and is sealed with the partition plate 2. The two ends of the outer shell 1 are fixedly mounted with sealing caps 43 for sealing the working chamber 3. The sealing caps 43 are provided with drive pipes 44 for driving the reciprocating flow of the driving fluid. The drive pipes 44 are connected to the liquid supply system.

[0038] The liquid supply system alternately inputs and outputs driving fluid to the driving areas at the ends of the two working chambers 3 through the driving pipe 44 on the sealing cover 43. Since the pistons 41 in the two working chambers 3 are fixedly connected by the connecting rod 42, and the connecting rod 42 is slidably sealed with the partition plate 2, when driving fluid is introduced into the driving area of ​​one side of the working chamber 3, the piston 41 on that side is pushed by the hydraulic pressure, and synchronously drives the piston 41 on the other side to move synchronously through the connecting rod 42, realizing the symmetrical reciprocating motion of the two pistons 41, thereby providing stable power for the liquid supply action of the two working chambers 3. The setting of the sealing cover 43 ensures the sealing of the working chambers 3, avoids driving fluid leakage, and ensures power transmission efficiency.

[0039] In this embodiment, the input component 8 includes an input pipe 81. One end of the input pipe 81 is connected to an oil storage container, and the other end of the input pipe 81 is connected to two working chambers 3 through an input interface 82. Each input interface 82 is equipped with an input one-way valve 83.

[0040] The input component 8 is responsible for replenishing oil to the two working chambers 3, and prevents oil backflow through a one-way structure. One end of the input pipe 81 is connected to the oil storage container, and the other end is connected to the two working chambers 3 respectively through two input interfaces 82.

[0041] When piston 41 reciprocates within working chamber 3, the liquid supply area within working chamber 3 alternates between negative and positive pressure. When negative pressure is generated in the liquid supply area, the oil in the oil storage container enters working chamber 3 through input pipe 81 and input interface 82. At this time, input check valve 83 in input interface 82 opens, allowing oil to flow in one direction. When positive pressure is generated in the liquid supply area, input check valve 83 closes, preventing oil from flowing back to the oil storage container. Simultaneously, the oil in the liquid supply area is compressed to form high pressure, and the high-pressure oil enters output pipe 6 through output interface 5. Output check valve 51 in output interface 5 opens, allowing oil to be output in one direction.
