Description

Technical Field

[0001] This utility model belongs to the field of air conditioner compressor crankshaft technology, and in particular relates to an air conditioner compressor crankshaft with high wear resistance. Background Technology

[0002] An air conditioning compressor is a device that compresses low-pressure refrigerant vapor into high-pressure vapor. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. The crankshaft of an air conditioning compressor has relatively high wear resistance and is typically made of materials with good wear resistance, such as high-strength steel. These materials possess excellent mechanical properties and wear resistance, enabling them to withstand the friction and wear during compressor operation. During manufacturing, the crankshaft undergoes heat treatment processes, such as quenching and tempering, to improve its hardness and wear resistance. These processes alter the material's microstructure, thereby enhancing its mechanical properties and wear resistance.

[0003] The crankshaft of an air conditioning compressor is a key component of a piston compressor. Its main function is to convert the rotary motion provided by the power source into reciprocating motion, thereby driving the piston to reciprocate within the compressor cylinder to achieve the refrigerant compression process. Currently, in the use of existing air conditioning compressor crankshafts, the various components are often fixed. When one part of the crankshaft is damaged, the entire crankshaft is often replaced, which is not cost-effective and does not allow for the replacement of corresponding parts according to usage requirements. Furthermore, the crank pins of the air conditioning compressor crankshaft do not provide adequate limiting effect on the connecting rod during use, and their contact with the lubricating oil is insufficient, increasing frictional losses. The problems with the above technology are: the various components of the air conditioning compressor crankshaft are often fixed, making it inconvenient to replace parts; the limiting effect on the connecting rod is insufficient; and the contact with the lubricating oil is inadequate. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an air conditioning compressor crankshaft with high wear resistance that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a crankshaft for an air conditioner compressor with high wear resistance includes a crankshaft component, a limiting assembly, and two protruding rods. The crankshaft component includes a connecting end, two crank arms, a crank pin, and an output end. The right sides of the two protruding rods are fixedly connected to the bottom left side of the left crank arm. The surfaces of the two protruding rods are inserted into the right side of the connecting end. The left and right sides of the crank pin are respectively attached to the top of the opposite ends of the two crank arms. The left side of the output end is fixedly connected to the bottom right side of the right crank arm. The limiting assembly is disposed on the surface of the crank pin. The limiting assembly includes two limiting rings, multiple through holes, and multiple threaded grooves. The interiors of the two limiting rings are slidably connected to the surface of the crank pin and can be fixed by bolts. The multiple through holes are respectively opened at the top and bottom of the interiors of the two limiting rings. The multiple threaded grooves are opened on the front side of the crank pin and are evenly distributed.

[0006] The crank is used to drive the piston;

[0007] The limiting component is used to limit the connecting rod.

[0008] To allow for the replacement of crank arms with different radii, preferably, plug-in blocks are fixedly connected to both sides of the crank pin. The surfaces of the two plug-in blocks are respectively plugged into the tops of the opposite ends of the two crank arms and can be fixed by bolts. After the two plug-in blocks are inserted into the interior of the two crank arms, the tops of the opposite sides of the two crank arms are fixed to the two plug-in blocks by mounting bolts. Crank arms with different radii will change the piston stroke.

[0009] In order to ensure timely replenishment of lubricating oil at the connection between the crank pin and the connecting rod, preferably, the crank pin has multiple oil holes inside, which are evenly distributed, and the surface of the crank pin has flow grooves. When the lubricating oil is on the surface of the crank pin, it can slide through the flow grooves. When it flows into the interior, it will carry away heat, preventing the crank pin from deforming or being damaged due to overheating, and covering the connection between the crank pin and the connecting rod with a layer of lubricating oil film.

[0010] To enhance the performance of the crank pin, preferably, multiple reinforcing ribs are fixedly connected inside each of the multiple oil holes and are evenly distributed. The use of multiple reinforcing ribs inside the multiple oil holes prevents the crank pin from breaking due to the multiple oil holes.

[0011] To prevent the crank pin from slipping after being inserted into the two crank arms, preferably, control blocks are fixedly connected to the top and bottom of the two insertion blocks. The surfaces of the multiple control blocks are respectively inserted into the top of the inner side of the opposite end of the two crank arms. The multiple control blocks all serve as limiters, making it easy for the crank pin to be inserted into the two crank arms through the multiple control blocks.

[0012] To facilitate fixing the connecting end to the left crank arm and to allow connection with other connecting parts, preferably, the right side of the inside of the connecting end and the inside of the two protruding rods are provided with mounting holes that are connected to each other. Bolts can be installed inside the multiple mounting holes, thereby connecting and fixing the connecting end to the left crank arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model, through the setting of structural components such as crankshaft parts, connecting ends, crank arms, and crank pins, allows the crank to drive the piston, the limiting component to limit the connecting rod, the plug-in block to replace crank arms of different radii, multiple oil holes and flow oil grooves to ensure timely replenishment of lubricating oil at the connection between the crank pin and the connecting rod, multiple reinforcing ribs to enhance the performance of the crank pin, the control block to prevent the crank pin from slipping after being plugged into the two crank arms, and the mounting hole to facilitate the fixing of the connecting end to the left crank arm and to connect with other connecting parts. It achieves the effect of facilitating the replacement of various crankshaft components, limiting the connecting rod, and ensuring better contact of the connecting rod and crankshaft pin with lubricating oil.

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5As shown in the figure, this utility model provides a highly wear-resistant air conditioning compressor crankshaft, including a crankshaft component 1, a limiting component 2, and two protruding rods 3. The crankshaft component 1 includes a connecting end 101, two crank arms 102, a crank pin 103, and an output end 104. The right sides of the two protruding rods 3 are fixedly connected to the bottom left side of the left crank arm 102, and the surfaces of the two protruding rods 3 are inserted into the right side of the connecting end 101. The left and right sides of the crank pin 103 are respectively attached to the top of the opposite ends of the two crank arms 102. The output end 104... The left and right sides of crank arm 102 are fixedly connected to the bottom of the right side. The limiting component 2 is set on the surface of crank pin 103. The limiting component 2 includes two limiting rings 201, multiple through holes 202 and multiple threaded grooves 203. The interior of the two limiting rings 201 is slidably connected to the surface of crank pin 103 and can be fixed by bolts. The multiple through holes 202 are respectively opened at the top and bottom of the interior of the two limiting rings 201. The multiple threaded grooves 203 are all opened on the front side of crank pin 103 and are evenly distributed. The crank is used to drive the piston.The limiting assembly 2 is used to limit the connecting rod. To allow for replacement of crank arms 102 with different radii, plug-in blocks 4 are fixedly connected to both sides of the crank pin 103. The surfaces of the two plug-in blocks 4 are respectively plugged into the tops of the opposite ends of the two crank arms 102 and can be fixed with bolts. After the two plug-in blocks 4 are inserted into the interior of the two crank arms 102, the tops of the opposite sides of the two crank arms 102 are then inserted into the interior of the two plug-in blocks 4 via mounting bolts, thus connecting the two plug-in blocks 4 to the two crank arms 102. 2. Fixed: Different radii of crank arms 102 will change the piston stroke. To ensure timely lubrication at the connection between the crank pin 103 and the connecting rod, multiple oil holes 5 are evenly distributed inside the crank pin 103. Flow grooves 6 are formed on the surface of the crank pin 103. When lubricating oil is on the surface of the crank pin 103, it can slide through the flow grooves 6. When it flows into the interior, it carries away heat, preventing the crank pin 103 from deforming or being damaged due to overheating, thus ensuring the connection between the crank pin 103 and the connecting rod is covered with lubricating oil. A layer of lubricating oil film is applied. To enhance the performance of the crank pin 103, multiple reinforcing ribs 7 are fixedly connected to the interior of each of the multiple oil holes 5, and are evenly distributed. The use of multiple reinforcing ribs 7 inside the multiple oil holes 5 prevents the crank pin 103 from breaking due to the multiple oil holes 5. To prevent the crank pin 103 from slipping after being inserted and connected to the two crank arms 102, control blocks 8 are fixedly connected to the top and bottom of the two insertion blocks 4. The surfaces of the multiple control blocks 8 are respectively inserted and connected to the top of the interior of the opposite ends of the two crank arms 102. The multiple control blocks 8 all serve a limiting function, facilitating the insertion and connection of the crank pin 103 to the two crank arms 102 through the multiple control blocks 8. To facilitate the fixing of the connecting end 101 to the left crank arm 102 and to connect with other connecting parts, the right side of the interior of the connecting end 101 and the interior of the two protruding rods 3 are provided with mounting holes 9, which are connected. Bolts can be installed inside the multiple mounting holes 9, thereby connecting and fixing the connecting end 101 to the left crank arm 102.

[0024] The working principle of this utility model:

[0025] When it is necessary to replace the crankshaft component 1, the connecting end 101 and the left crank arm 102 are separated by removing the bolts fixing the connecting end 101 and the left crank arm 102. The two crank arms 102 and the two plug blocks 4 are then removed to separate the two crank arms 102 from the crank pin 103, allowing for replacement of the component as needed. The connecting end 101 is connected to the left crank arm 102 by two protruding rods 3 and then fixed with bolts. The two crank arms 102 are connected to the crank pin 103 by two plug blocks 4 and then fixed with bolts. After the connecting rod is connected to the crank pin 103, the position of the two limiting rings 201 is changed according to the size of the connecting rod. The bolts fixing the two limiting rings 201 to the crank pin 103 are removed, and then the two limiting rings 201 are moved to the left or right and fixed with the corresponding threaded grooves 203 by bolts. During use, the lubricating oil can be replenished in a timely manner through the flow oil groove 6, multiple oil holes 5, and multiple through holes 202.
