Description

Technical Field

[0001] The invention relates to the field of gear chambers, and in particular to a gear chamber device for an air compressor. Background Art

[0002] The air compressor gear housing device is a specially designed mechanical device used to connect the air compressor to the engine's power system. This device usually includes components such as the gear housing body, the air compressor idler gear, the air compressor idler gear shaft and the air compressor gear.

[0003] For the transmission of gear structure, if the mutual friction is very large, it will accelerate the wear of the gears and produce stronger vibration and noise. For this reason, it is necessary to add lubricating oil to the gears regularly to reduce the mutual friction between the gears. For the traditional gear chamber structure, the way to add lubricating oil is mainly manual addition. This adding method cannot guarantee the injection amount of lubricating oil. That is, there will be more or less situations. When there is a significant difference between the injection amount of lubricating oil and the standard amount, it will affect the interval time of the next injection of lubricating oil, and it is easy to fail to add lubricating oil in time within the specified time.

[0004] Therefore, it is necessary to provide a new gear chamber device for an air compressor to solve the above-mentioned technical problems. Summary of the invention

The transmission rod extends axially into the storage container, and a piston is fixed to the upper end of the transmission rod.

[0015] Preferably, the outer wall of the transmission rod has spiral teeth, and the spiral teeth and the storage container are spirally driven to generate self-rotation during the axial movement of the transmission rod;

[0016] A plurality of annularly distributed stirring plates are fixed on one side of the piston, and the stirring plates are driven by the piston to rotate together to achieve stirring of the lubricating oil inside the storage container.

[0017] Preferably, the heat conducting member comprises a connecting plate, one end of the connecting plate is integrally connected with a collar, the collar is sleeved on the bearing seat, and the other end of the connecting plate is integrally connected with a clamp, the clamp is clamped to the outside of the storage container.

[0022] 3. The transmission rod and the storage container are spirally driven. Therefore, during the axial displacement of the transmission rod, it will rotate, thereby driving the piston to rotate together. There are multiple stirring plates on the piston. During the rotation of the piston, the stirring plates can be used to stir the lubricating oil inside the storage container to improve the fluidity of the lubricating oil, thereby further improving the spraying effect of the lubricating oil.

[0023] 4. When the gear is rotating, the bearing seat will heat up, and the heat can be conducted through the copper connecting plate, collar and chuck and other structures, that is, the heat is conducted to the storage container. Therefore, when used in a relatively cold environment, it can be used to keep the internal temperature of the storage container constant to avoid the lubricating oil solidifying due to too low temperature.

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] See also Figures 1 to 6 The gear chamber device for an air compressor provided in an embodiment of the present invention comprises a gear chamber body 1, a bearing seat 3 is fixed to the side of the gear chamber body 1, a transmission shaft 4 for fixing the gear set 2 is rotatably connected to the bearing seat 3, and also comprises a monitoring unit 5, an oil injection unit 6 and a heat conductor 7.

[0037] It should be noted that: in the device, a monitoring unit 5 is provided on the gear chamber body 1, and the monitoring unit 5 is used to monitor the vibration change and noise change inside the gear chamber body 1, that is, when the lubricating oil in the gear set 2 is not consumed, the friction between the gears will be relatively small, so the vibration and noise generated during the transmission process will also be relatively small; when the lubricating oil between the gear sets 2 is consumed, the friction between the gears will be relatively large, so the vibration and noise generated during the transmission process will increase. When obvious changes in vibration and noise are monitored, the information will be transmitted to the oil injection unit 6, and the oil injection unit 6 will be used to add lubricating oil;

[0038] The oil filling unit 6 is an automatic oil filling structure, so when lubricating oil needs to be added, it can automatically add lubricating oil. When used together with the monitoring unit 5, the lubricating oil can be added at the first time, which has a better protection effect on the transmission gears, and can also accurately control the amount of lubricating oil to avoid waste;

[0039] The heat conductor 7 is a structure for conducting heat. In some colder areas, the temperature is relatively low. Under low temperature conditions, the lubricating oil is prone to solidification, affecting normal use. Therefore, the heat conductor 7 is provided to conduct heat, that is, one end of the heat conductor 7 is installed on the bearing seat 3. During the rotation of the transmission shaft 4, the bearing seat 3 will heat up, and the temperature can be directly conducted to the heat conductor 7, and the other end of the heat conductor 7 is fixed on the oil injection unit 6, so that the heat can be conducted to the oil injection unit 6, which is used to increase the temperature of the lubricating oil in a low temperature environment so that it is always maintained within the range of 0-25°C.

[0040] In the embodiments of the present invention, please refer to Figure 3 The monitoring unit 5 includes a first mounting frame 51, which is fixed to the outside of the gear chamber body 1. A vibration sensor 52 and a noise sensor 53 are also mounted on the first mounting frame 51. The vibration sensor 52 and the noise sensor 53 both have a probe 54.

[0041] The probes 54 in the vibration sensor 52 and the noise sensor 53 directly contact the outer wall of the gear chamber body 1 .

[0042] It should be noted that the monitoring unit 5 includes a vibration sensor 52 and a noise sensor 53. The vibration sensor 52 is used to monitor the vibration change of the gear chamber itself, while the noise sensor 53 is used to monitor the noise change inside the gear chamber. When the vibration factor and the noise factor exceed the rated standard, lubricating oil needs to be added for lubrication. Therefore, lubricating oil can be added at the first time to improve the protection effect of the gear transmission structure.

[0043] At the same time, the probes 54 in the vibration sensor 52 and the noise sensor 53 are directly mounted on the outer wall of the gear chamber body 1, so the monitoring accuracy will be higher.

[0044] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The oil injection unit 6 is fixed to the outside of the gear chamber body 1, and the oil injection unit 6 includes a second mounting frame 61, and the second mounting frame 61 is fixed to the outside of the gear chamber body 1, and an oil storage and delivery part and a driving part are fixed on the second mounting frame 61;

[0045] The oil storage and delivery part includes a storage container 62, which is vertically fixed on the second mounting frame 61. Lubricating oil is contained in the storage container 62. An oil filling port 63 and an oil outlet are provided near the top of the storage container 62. A second one-way valve 65 is fixed to the other end of the oil outlet. A guide pipe 66 is fixed to the other end of the second one-way valve 65. A nozzle 67 is fixed to the other end of the guide pipe 66. The nozzle 67 is fixed to the gear chamber body 1 and communicates with the inside of the gear chamber body 1. The nozzle faces the position of the gear set 2 and is used to spray the lubricating oil onto the gear set 2 in a mist form. At the same time, an air inlet is also provided at the top of the storage container 62, and a first one-way valve 64 is fixed to the air inlet.

[0046] The driving part includes a cylinder 68, which is fixed on the second mounting frame 61 and is located below the storage container 62. The output end of the cylinder 68 is rotatably connected to a transmission rod 610 through a rotary joint 69. The transmission rod 610 axially extends into the storage container 62. A piston 611 is fixed to the upper end of the transmission rod 610.

[0047] The outer wall of the transmission rod 610 has spiral teeth, and the spiral teeth and the storage container 62 are used for spiral transmission, so that the transmission rod 610 generates self-rotation during the axial movement;

[0048] A plurality of annularly distributed stirring plates 612 are fixed to one side of the piston 611 , and the piston 611 drives the stirring plates 612 to rotate together, thereby stirring the lubricating oil inside the storage container 62 .

[0049] It should be noted that when lubricating oil needs to be injected, the transmission rod 610 is driven by the cylinder 68 to move, and the other end of the transmission rod 610 extends into the storage container 62. At the same time, a piston 611 is fixed to the end, so that the lubricating oil in the storage container 62 can be squeezed out during the movement, so that the lubricating oil passes through the second one-way valve 65 and enters the guide pipe 66, and then sprays out from the nozzle 67, which is facing the position of the gear set 2, so that the lubricating oil can be sprayed in a mist form;

[0050] The transmission rod 610 has spiral teeth on the outside, and the spiral teeth and the storage container 62 form a spiral transmission, that is, during the axial movement of the transmission rod 610, it will also rotate. One end of the transmission rod 610 is installed on the output end of the cylinder 68 through a rotary joint 69. Therefore, when the cylinder 68 drives the transmission rod 610 to move, it will not affect the rotation of the transmission rod 610. When the transmission rod 610 rotates, it can drive the piston 611 to rotate together. There are multiple stirring plates 612 at the other end of the piston 611. Therefore, during the rotation process, the lubricating oil in the storage container 62 can be stirred to improve the fluidity of the lubricating oil and improve the delivery and spraying effect of the lubricating oil.

[0051] When the lubricating oil in the storage container 62 needs to be increased, it can be directly injected from the oil filling port 63 . At the same time, when the reverse drive transmission rod 610 moves, gas enters from the air inlet to balance the pressure in the storage container 62 .

[0052] In the embodiments of the present invention, please refer to Figure 6 The heat conducting member 7 includes a connecting plate 71, one end of the connecting plate 71 is integrally connected with a collar 72, the collar 72 is sleeved on the bearing seat 3, and the other end of the connecting plate 71 is integrally connected with a clamp 73, the clamp 73 is clamped to the outside of the storage container 62;

[0053] The connecting plate 71 , the collar 72 and the clamp 73 are all made of copper.

[0054] It should be noted that: the heat conducting member 7 is based on the connecting plate 71, one end of which has a collar 72 and the other end has a clamp 73, and the collar 72 is mounted on the bearing seat 3 in a sleeve manner, and the clamp 73 is mounted on the storage container 62 in a clamping manner, so the disassembly and assembly operation is very convenient. In an environment with a high temperature, the structure can be disassembled to avoid the lubricating oil from failing due to excessive temperature;

[0055] The connecting plate 71, the collar 72 and the clamp 73 are an integrated structure and are made entirely of copper, which has better thermal conductivity.

[0056] The specific usage process of the device is as follows:

[0057] (1) Monitoring;

[0058] The vibration sensor 52 and the noise sensor 53 monitor the vibration and noise factors inside the gear chamber body 1. When the lubricating oil in the gear set 2 is not consumed, the friction between the gears will be relatively small, so the vibration and noise generated during the transmission process will also be relatively small; when the lubricating oil between the gear set 2 is consumed, the friction between the gears will be relatively large, so the vibration and noise generated during the transmission process will increase. When obvious changes in vibration and noise are monitored, the information will be transmitted to the oil injection unit 6, and the oil injection unit 6 will be used to add lubricating oil;

[0059] (2), oil injection;

[0060] The transmission rod 610 is driven by the cylinder 68 to move, and the other end of the transmission rod 610 extends into the storage container 62. At the same time, a piston 611 is fixed to the end, so that the lubricating oil in the storage container 62 can be squeezed out during the movement, so that the lubricating oil passes through the second one-way valve 65 and enters the guide pipe 66, and then sprays out from the nozzle 67. The nozzle 67 is facing the position of the gear set 2, so that the lubricating oil can be sprayed in a mist form;

[0061] The transmission rod 610 has spiral teeth on the outside, and the spiral teeth and the storage container 62 form a spiral transmission, that is, during the axial movement of the transmission rod 610, it will also rotate. One end of the transmission rod 610 is installed on the output end of the cylinder 68 through a rotary joint 69. Therefore, when the cylinder 68 drives the transmission rod 610 to move, it will not affect the rotation of the transmission rod 610. When the transmission rod 610 rotates, it can drive the piston 611 to rotate together. There are multiple stirring plates 612 at the other end of the piston 611. Therefore, during the rotation process, the lubricating oil in the storage container 62 can be stirred to improve the fluidity of the lubricating oil and improve the delivery and spraying effect of the lubricating oil.

[0062] (3) Thermal conductivity;

[0063] When the temperature is relatively low, the heat conducting member 7 may be installed to maintain a constant temperature inside the storage container 62 to prevent the lubricating fluid inside the storage container 62 from solidifying;

[0064] For the heat conducting member 7, a connecting plate 71 is used as a basis, one end of which has a collar 72 and the other end of which has a clamp 73. The collar 72 is mounted on the bearing seat 3 in a sleeve manner, and the clamp 73 is mounted on the storage container 62 in a clamping manner. Therefore, the disassembly and assembly operation is very convenient. In an environment with relatively high temperature, the structure can be removed to avoid the lubricating oil from becoming ineffective due to excessive temperature. The connecting plate 71, the collar 72 and the clamp 73 are an integrated structure, and the whole is made of copper, so its thermal conductivity will be better.

[0065] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
