Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a compressor clutch device, a compressor, an air conditioner, and operating machinery. Background Technology

[0002] With the diversified application and development of construction machinery, the structure of construction machinery is becoming more refined, user-friendly, and convenient for operation and maintenance. For example, taking excavators as an example, most of them use electromagnetic friction clutches as the clutch for air conditioning compressors. An electromagnetic friction clutch includes an electromagnetic coil 1' and a friction disc 2'. Figure 1 As shown, an electromagnetic coil 1' is fixed to the compressor housing 3', and a friction disc 2' is mounted on the compressor main shaft 4'. A pulley 5' is also mounted on the compressor main shaft 4' via a transmission bearing. When the electromagnetic coil 1' is energized, it generates electromagnetic attraction, which causes the friction disc 2' to engage with the pulley 5', causing both the friction disc 2' and the compressor main shaft 4' to rotate with the pulley 5', thus initiating compressor operation.

[0003] When assembling a clutch on a compressor, the drive bearing is typically positioned between the hub of pulley 5' and the compressor's main shaft 4', fixing the clutch's electromagnetic coil 1' to the compressor housing 3'. To ensure that the friction disc 2' effectively engages with pulley 5' when energized, the electromagnetic coil 1' is embedded within pulley 5', positioned on the spokes and close to the rim. To ensure smooth rotation of pulley 5' relative to both the electromagnetic coil 1' and the compressor housing 3', gaps are provided between pulley 5' and the electromagnetic coil 1', and between pulley 5' and the compressor housing 3'.

[0004] The excavator operates in a harsh environment. When the engine drives the compressor, the engine's cooling water fan draws in a large amount of dust around the compressor. This dust can then enter the gap between the pulley 5' and the solenoid coil 1' through the gap between the pulley 5' and the compressor housing 3', resulting in poor dust prevention. Once dust enters the gap between the solenoid coil 1' and the pulley 5', it can cause the coil to jam, affecting the pulley's rotation. Furthermore, in rainy or snowy weather, rainwater and snowmelt can enter the gap between the solenoid coil 1' and the pulley 5', combining with dust to form mud. In low temperatures, such as in winter, the water or mud can freeze the solenoid coil 1' and the pulley 5' together, creating a strong connection that causes the coil 1' to rotate with the pulley 5'. This can damage the connection between the solenoid coil 1' and the compressor housing 3', and may even break the coil.

[0005] Therefore, how to solve the problem that the electromagnetic coil is easily damaged when dust or water enters the gap between the electromagnetic coil and the pulley in the compressor clutch device of the prior art has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0006] This invention provides a compressor clutch device, a compressor, an air conditioner, and a work machine to solve the defect in the prior art compressor clutch device that the electromagnetic coil part is easily damaged due to dust or water entering the gap between the electromagnetic coil part and the transmission wheel during operation.

[0007] This invention provides a compressor clutch device, comprising:

[0008] The mounting base is fixed relative to the compressor housing. The mounting base is arranged around the outside of the compressor main shaft. The mounting base is provided with an installation space, and the end of the installation space near the compressor housing is closed.

[0009] An electromagnetic coil section is disposed within the mounting space and is fixed relative to the mounting base;

[0010] A drive wheel is rotatably connected to the mounting base, and the drive wheel is located outside the electromagnetic coil section;

[0011] A drive disk is disposed on the compressor main shaft and can rotate synchronously with the compressor main shaft. The drive disk is located on the side of the transmission wheel away from the compressor housing. When the electromagnetic coil is energized, the drive disk and the transmission wheel are attracted to each other, and the installation space is closed.

[0012] When the compressor is running, the installation space where the electromagnetic coil is located is in a closed state, isolating the electromagnetic coil from the external space. This effectively prevents water or dust from entering the installation space, thus preventing water or dust from entering the gap between the electromagnetic coil and its surrounding components. This avoids the problem of damage to the electromagnetic coil caused by strong connections between the electromagnetic coil and its surrounding components. It solves the problem in the existing compressor clutch device where the electromagnetic coil is easily damaged due to dust or water entering the gap between the electromagnetic coil and the transmission wheel during operation, and can reduce the probability of air conditioner malfunctions.

[0013] According to a compressor clutch device provided by the present invention, an annular flange is provided on the transmission wheel, the annular flange is located on the side of the transmission wheel away from the compressor housing, and the drive disc is located inside the annular flange.

[0014] When the compressor stops running, the gap between the drive disc and the transmission wheel is located inside the annular flange. The annular flange can cover the gap between the drive disc and the transmission wheel, reducing the possibility of dust and water entering the installation space.

[0015] According to a compressor clutch device provided by the present invention, the hub of the transmission wheel extends into the mounting space and is arranged around the outer periphery of the electromagnetic coil portion. The axis of the hub coincides with the axis of the compressor main shaft, and the hub is rotatably connected to the mounting base.

[0016] Typically, a bearing is used to rotatably connect the hub of the drive wheel to the mounting base. In this configuration, the bearing is located within the mounting space and surrounded by the mounting base and the drive wheel, effectively isolating it from external dust and other contaminants. The bearing also acts as a seal, further reducing the possibility of dust or water entering the gap around the solenoid coil from the end near the compressor housing.

[0017] A compressor clutch device according to the present invention further includes:

[0018] A bearing is disposed within the mounting space and located between the hub and the mounting base. The outer ring of the bearing is fixedly connected to the mounting base, and the inner ring of the bearing is fixedly connected to the hub.

[0019] The drive wheel and the mounting base are rotated through the bearing. At the same time, the bearing is located in the installation space and is surrounded by the mounting base and the drive wheel, thus isolating the bearing from external dust and other contaminants.

[0020] According to a compressor clutch device provided by the present invention, a fan blade assembly is provided on the transmission wheel, the fan blade assembly is located on the side of the transmission wheel close to the compressor housing, the fan blade assembly is fixed relative to the transmission wheel, and a communication hole for gas flow is provided on the transmission wheel;

[0021] The fan blade assembly is configured to create a negative pressure state in the connecting hole when rotating, allowing gas to flow into the compressor housing.

[0022] When the engine drives the drive wheel to rotate, the fan blade assembly rotates synchronously with the drive wheel, allowing gas to flow into the compressor casing. This provides air-cooled cooling to the compressor, preventing malfunctions caused by high temperatures during operation. Replacing the dedicated cooling fan in existing technologies with a fan blade assembly mounted on the drive wheel eliminates the need for a separate cooling fan, reducing costs, minimizing space requirements, and increasing the compressor's integration level.

[0023] According to a compressor clutch device provided by the present invention, the fan blade assembly includes:

[0024] A blade assembly, comprising at least two blades;

[0025] A flow guide is disposed around the outside of the blade assembly. One end of the flow guide is connected to the drive wheel, and the other end extends in a direction close to the compressor housing. The cross-sectional dimensions of the flow guide gradually increase in the direction close to the compressor housing. The blades are distributed circumferentially along the flow guide.

[0026] With this configuration, as the fan blade assembly rotates with the drive wheel, it guides the gas to the periphery of the compressor housing, which helps to increase the cooling area of ​​the compressor and improve the cooling effect.

[0027] According to a compressor clutch device provided by the present invention, the drive disc includes:

[0028] The fixing part is used to fix it to the compressor main shaft;

[0029] The friction disc portion has a ring-shaped structure extending circumferentially along the fixed portion, and the friction disc portion is configured to interact with the transmission wheel;

[0030] An elastic connecting portion is disposed between the fixed portion and the friction disc portion, and the elastic connecting portion is configured to cause the friction disc portion to tend to move away from the transmission wheel.

[0031] The present invention also provides a compressor, including a compressor body and a compressor clutch device, wherein the compressor clutch device is the compressor clutch device described above.

[0032] The present invention also provides an air conditioner, including the compressor clutch device described above, or including the compressor described above.

[0033] The present invention also provides a working machine, including the compressor clutch device described above, or including the compressor described above, or including the air conditioner described above.

[0034] The compressor clutch device provided by this invention includes a mounting base, a transmission wheel, an electromagnetic coil, and a drive disc. The mounting base is fixed relative to the compressor housing and is arranged around the outside of the compressor main shaft. The mounting base has an installation space, and the end of the installation space near the compressor housing is closed. The electromagnetic coil is placed in the installation space and fixed relative to the mounting base. The transmission wheel is rotatably connected to the mounting base. The drive disc is mounted on the compressor main shaft, allowing it to rotate synchronously with the compressor main shaft. The drive disc is located on the side of the transmission wheel away from the compressor housing. When the electromagnetic coil is energized, the drive disc and the transmission wheel are attracted together, and the drive disc rotates synchronously with the transmission wheel, thereby driving the compressor main shaft to rotate and enabling the compressor to operate. The drive wheel is located outside the electromagnetic coil section. After the drive disc engages with the drive wheel, it can seal the installation space, isolating the electromagnetic coil section from the external space. This effectively prevents water or dust from entering the installation space, thus preventing water or dust from entering the gap between the electromagnetic coil section and its surrounding components. This avoids the problem of damage to the electromagnetic coil section caused by strong connections between the electromagnetic coil section and its surrounding components. It solves the problem in the prior art where the compressor clutch device is easily damaged by dust or water entering the gap between the electromagnetic coil and the pulley during operation, thereby reducing the probability of air conditioner malfunctions.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0050] The following is combined with Figures 2 to 8 The compressor clutch device of the present invention is described.

[0051] like Figures 2 to 8 As shown, the compressor clutch device provided in this embodiment of the invention includes a mounting base 1, a transmission wheel 5, an electromagnetic coil part 4, and a drive disc 6.

[0052] Specifically, the mounting base 1 is fixed relative to the compressor housing 2 and is arranged around the outside of the compressor main shaft 3. The end of the mounting base 1 away from the compressor housing 2 is provided with a mounting space for accommodating the electromagnetic coil part 4. The end of the mounting space near the compressor housing 2 is closed, and the end of the mounting space away from the compressor housing 2 is open to facilitate the insertion of the electromagnetic coil part 4.

[0053] Mounting base 1 has a cylindrical structure with a certain wall thickness, and the aforementioned installation space can be an annular groove provided on mounting base 1.

[0054] The mounting base 1 described above can be integrally formed with the compressor housing 2 as part of the compressor housing 2. Alternatively, the mounting base 1 can be machined separately and fixedly connected to the compressor housing 2 by bolts or welding.

[0055] When placing the electromagnetic coil part 4 within the installation space, it is necessary to fix the electromagnetic coil part 4 relative to the mounting base 1. Specifically, the electromagnetic coil part 4 and the mounting base 1 can be fixedly connected together by bolts. Alternatively, a limiting hole can be provided on the end face of the electromagnetic coil part 4 near the compressor housing 2, and a limiting post can be provided at the corresponding position on the mounting base 1 or the compressor housing 2, so that the limiting post cooperates with the limiting hole to restrict the rotation of the electromagnetic coil part 4 relative to the mounting base 1 or the compressor housing 2.

[0056] The drive wheel 5 is rotatably connected to the mounting base 1. The drive wheel 5 is connected to the output shaft of the engine through a transmission mechanism. When the engine is running, it can drive the drive wheel 5 to rotate relative to the compressor housing 2.

[0057] In a specific embodiment, the transmission wheel 5 can be a belt pulley, and the transmission mechanism between the engine and the transmission wheel 5 is set as a belt drive. Connecting the transmission wheel 5 to the output shaft of the engine via a belt drive mechanism helps to reduce the accuracy requirements for the installation positions of the engine and the transmission wheel 5, and facilitates the arrangement of the positions of the engine and the compressor.

[0058] The drive disk 6 is mounted on the compressor main shaft 3, and the drive disk 6 can rotate synchronously with the compressor main shaft 3.

[0059] The drive disc 6 is positioned on the side of the transmission wheel 5 away from the compressor housing 2. When the electromagnetic coil 4 is energized, it generates an electromagnetic attraction, causing the drive disc 6 to approach the electromagnetic coil 4 and engage with the transmission wheel 5. The drive disc 6 rotates synchronously with the transmission wheel 5, thereby driving the compressor main shaft 3 to rotate and enabling the compressor to operate.

[0060] The transmission wheel 5 is located outside the electromagnetic coil part 4. After the drive disc 6 engages with the transmission wheel 5, it can seal the installation space and isolate the electromagnetic coil part 4 from the external space. This can effectively prevent water or dust from entering the installation space, thereby preventing water or dust from entering the gap between the electromagnetic coil part 4 and its surrounding components. This avoids the problem of damage to the electromagnetic coil part 4 caused by strong connection between the electromagnetic coil part 4 and its surrounding components. It solves the problem in the prior art where the compressor clutch device is easily damaged by dust or water entering the gap between the electromagnetic coil and the pulley during operation, and can reduce the probability of air conditioner malfunction.

[0061] In this embodiment, the drive disk 6 includes a fixing part, a friction disk part, and an elastic connecting part.

[0062] Specifically, the fixing part is used to fix it to the compressor main shaft 3. The fixing part can be set as a disc-shaped structure, and the fixing part is sleeved on the outside of the compressor main shaft 3, and the fixing part is interference-fitted with the compressor main shaft 3 so that the fixing part is relatively fixed to the compressor main shaft 3.

[0063] In order to effectively transmit torque between the fixed part and the compressor main shaft 3 and ensure that the fixed part can drive the compressor main shaft 3 to rotate, a key can be set between the fixed part and the compressor main shaft 3. The interaction between the key and the fixed part, as well as the interaction between the key and the compressor main shaft 3, can fix the fixed part and the compressor main shaft 3 circumferentially.

[0064] The friction disc is used to interact with the transmission wheel 5. In this embodiment, the friction disc is configured as a ring structure, so that the friction disc can be arranged around the periphery of the fixed part. An elastic connecting part is provided between the fixed part and the friction disc, and both the friction disc and the fixed part are connected to the elastic connecting part, that is, the friction disc and the fixed part are elastically connected.

[0065] The elastic connection is configured to cause the friction disc to tend to move away from the drive wheel 5.

[0066] When the electromagnetic coil 4 is energized, it generates an electromagnetic attraction. Under the action of the electromagnetic attraction, the friction disc overcomes the elastic force of the elastic connection and moves towards the electromagnetic coil 4, thereby pressing against the transmission wheel 5 and engaging with it. At this time, the compressor clutch device is in the engaged state.

[0067] When the electromagnetic coil 4 is de-energized, the electromagnetic attraction disappears, and the friction disc gradually moves away from the transmission wheel 5 under the action of the elastic connection, disengaging from the transmission wheel 5. At this time, the compressor clutch device is in a disengaged state.

[0068] In an optional embodiment, to ensure that the friction disc and the transmission wheel 5 can effectively transmit torque, a protrusion can be provided on one of the friction disc and the transmission wheel 5, and a groove can be provided on the other. When the friction disc and the transmission wheel 5 are attracted together, the protrusion is embedded in the groove. Through the interaction between the protrusion and the groove, the friction disc and the transmission wheel 5 can effectively transmit torque.

[0069] In a specific embodiment, the material of the above-mentioned elastic connection part may be, but is not limited to, rubber.

[0070] The elastic connector is designed as a ring structure, so that the inner edge of the elastic connector is fixedly connected to the outer edge of the fixed part, and the sealing of the connection between the elastic connector and the fixed part is ensured.

[0071] Accordingly, the outer edge of the elastic connector is fixedly connected to the inner edge of the friction disc, and the sealing of the connection between the elastic connector and the friction disc is ensured.

[0072] The use of rubber for the elastic connecting parts can also alleviate the impact between the friction disc and the fixed part, reducing noise.

[0073] When the electromagnetic coil 4 is de-energized, the drive disc 6 loses contact with the transmission wheel 5, and the transmission wheel 5 cannot drive the compressor main shaft 3 to rotate, causing the compressor to stop running. At this time, there is a gap between the drive disc 6 and the transmission wheel 5.

[0074] To prevent external water or dust from entering the gap between the drive disc 6 and the transmission wheel 5, and the gap between the electromagnetic coil part 4 and its surrounding components, when the compressor is not running, an annular flange 7 is provided on the transmission wheel 5 in this embodiment of the invention. The annular flange 7 is located on the side of the transmission wheel 5 away from the compressor housing 2. The drive disc 6 is located inside the annular flange 7. When the electromagnetic coil part 4 is de-energized, the gap between the drive disc 6 and the transmission wheel 5 is located inside the annular flange 7. The annular flange 7 can cover the gap between the drive disc 6 and the transmission wheel 5, reducing the possibility of dust and water entering the installation space.

[0075] In a further embodiment, a felt ring 17 is fixedly provided on the inner circle of the annular flange 7. The felt ring 17 is located between the inner circle of the annular flange 7 and the outer circle of the drive disk 6, which can further reduce the possibility of dust entering the installation space from the gap between the annular flange 7 and the drive disk 6.

[0076] The drive wheel 5 has a hub portion 12 and a rim portion 13. The hub portion 12 is rotatably connected to the mounting base 1, and the outer circle of the rim portion 13 is provided with a groove 14 for cooperating with the drive belt.

[0077] In some embodiments, the hub portion 12 of the transmission wheel 5 is sleeved on the outside of the mounting base 1, and a bearing is provided between the hub portion 12 and the mounting base 1, so that the outer side wall of the mounting base 1 is fixedly connected to the inner ring of the bearing, and the inner side wall of the hub portion 12 is fixedly connected to the outer ring of the bearing, thereby realizing the rotational connection between the transmission wheel 5 and the mounting base 1.

[0078] In this embodiment, the hub portion 12 of the transmission wheel 5 protrudes beyond the rim portion 13, and the hub portion 12 extends into the mounting space, as shown in the figure. Figure 2 The hub portion 12 is arranged around the outer periphery of the electromagnetic coil portion 4, and the axis of the hub portion 12 coincides with the axis of the compressor main shaft 3. A bearing 15 is provided between the hub portion 12 and the mounting base 1, so that the outer side wall of the hub portion 12 is fixedly connected to the inner ring of the bearing 15, and the inner side wall of the mounting base 1 is fixedly connected to the outer ring of the bearing 15, thereby realizing the rotational connection between the transmission wheel 5 and the mounting base 1. At this time, the bearing 15 is located in the installation space and is surrounded by the mounting base 1 and the transmission wheel 5, thus isolating the bearing 15 from external dust and other contaminants.

[0079] In addition, the bearing 15 acts as a seal, which can further reduce the possibility of dust or water entering the gap around the electromagnetic coil section 4 from the end of the electromagnetic coil section 4 near the compressor housing 2.

[0080] It should be noted that there needs to be a gap between the electromagnetic coil part 4 and the compressor main shaft 3, and a gap between the electromagnetic coil part 4 and the hub part 12.

[0081] When a compressor is running, it generates a lot of heat, causing the compressor temperature to rise. When the compressor temperature is too high, the internal piston may experience poor lubrication, leading to abnormal wear or even seizing, rendering the compressor unable to operate.

[0082] In this embodiment of the invention, a fan blade assembly 8 is provided on the transmission wheel 5. The fan blade assembly 8 is located on the side of the transmission wheel 5 near the compressor housing 2, and the fan blade assembly 8 is fixed relative to the transmission wheel 5.

[0083] Specifically, the fan blade assembly 8 and the drive wheel 5 can be integrally machined. Alternatively, the fan blade assembly 8 and the drive wheel 5 can be machined separately, and then the fan blade assembly 8 and the drive wheel 5 can be fixedly connected together.

[0084] A connecting hole 9 is provided on the transmission wheel 5. The connecting hole 9 passes through the transmission wheel 5 and connects the spaces on both sides of the transmission wheel 5 to allow gas to flow.

[0085] When the engine drives the transmission wheel 5 to rotate, the fan blade assembly 8 rotates synchronously with the transmission wheel 5. The fan blade assembly 8 can create a negative pressure state at the connecting hole 9, and after pressurizing the gas, it allows the gas to flow into the compressor housing 2, such as... Figure 5 As shown.

[0086] When gas flows to the compressor housing 2, it can provide air-cooled cooling to prevent malfunctions caused by overheating during compressor operation. The fan blade assembly 8 mounted on the drive wheel 5 replaces the dedicated cooling fan in the prior art, eliminating the need for a separate cooling fan, reducing costs, minimizing space requirements, and improving the compressor's integration level.

[0087] In this embodiment, the fan blade assembly 8 includes a blade assembly and a flow guide 11.

[0088] Specifically, the blade assembly is disposed inside the fairing 11, and the blade assembly includes at least two blades 10, which are distributed circumferentially along the fairing 11. Figure 6 .

[0089] One end of the flow guide shroud 11 is connected to the drive wheel 5, and the other end extends along the direction close to the compressor housing 2, with the cross-sectional dimensions of the flow guide shroud 11 gradually increasing along the direction close to the compressor housing 2. This allows the cross-sectional dimension of the end of the flow guide shroud 11 close to the compressor housing 2 to be slightly larger than the external dimensions of the compressor housing 2. As the fan blade assembly 8 rotates with the drive wheel 5, it guides the gas to the periphery of the compressor housing 2, which helps to increase the cooling area of ​​the compressor and improve the cooling effect.

[0090] There are at least two connecting holes 9, and the number of connecting holes 9 corresponds one-to-one with the number of blades 10, and the connecting holes 9 are located between adjacent blades 10.

[0091] To reduce the space occupied by the fan blade assembly 8 and the drive wheel 5, an annular groove 16 can be provided on the side of the drive wheel 5 near the compressor housing 2, such as... Figure 6 and Figure 8 As shown, the fan blade assembly 8 is placed in the annular groove 16.

[0092] In summary, the compressor clutch device provided by this invention not only has excellent waterproof and dustproof effects, preventing damage to the electromagnetic coil caused by dust or water entering the gap between the electromagnetic coil and surrounding components, thus reducing the compressor's failure rate, but also eliminates the need for additional waterproof and dustproof devices when assembled onto engineering machinery. Furthermore, it boasts the advantages of simple structure and ease of implementation, without increasing the production cost of the compressor clutch device during actual implementation.

[0093] Furthermore, the compressor clutch device in this embodiment integrates the transmission wheel 5 and the fan blade assembly 8 into one unit, giving the compressor an independent cooling and heat dissipation structure. This prevents the compressor from malfunctioning due to excessive temperature, which helps to improve the compressor's service life and further reduce the compressor's failure rate.

[0094] The fan blade assembly 8 rotates under the drive of the transmission wheel 5, eliminating the need for an additional power unit and thus reducing energy consumption.

[0095] On the other hand, embodiments of the present invention also provide a compressor, including a compressor body and a compressor clutch device provided in any of the above embodiments. The compressor body includes a compressor main shaft 3 and a compressor housing 2. The compressor clutch device is connected to the compressor housing 2 and the compressor main shaft 3 of the compressor body. The compressor clutch device in the above embodiments has excellent dustproof and waterproof effects, effectively preventing water or dust from entering the gap between the electromagnetic coil part 4 and its surrounding components, and effectively avoiding damage to the electromagnetic coil part 4 caused by strong connection between the electromagnetic coil part 4 and its surrounding components. Therefore, the compressor in this embodiment also has excellent dustproof and waterproof effects, which can reduce the problem of damage to the electromagnetic coil part 4, extend its service life, and reduce the probability of air conditioner malfunction. The derivation process of the beneficial effects of the compressor in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the compressor clutch device described above, so it will not be repeated here.
