Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a balancing mechanism for a four-cylinder piston compressor designed based on a dynamic balancing method. Background Art

[0002] A piston air compressor is an air compressor that changes its internal volume by relying on a cylinder and a piston that reciprocates in the cylinder. After the motor is started, it drives the crankshaft to rotate. Through the transmission of the connecting rod, the piston reciprocates and the working volume changes periodically. The crankshaft rotates one circle and the piston reciprocates once, and the process of intake, compression and exhaust is realized in the cylinder successively, completing a working cycle.

[0003] According to the Chinese patent publication number CN202811256U, the patent provides a double-shaft four-cylinder direct-connected oil-free air compressor, including a motor and a compression cylinder. The motor is equipped with a motor shaft with shafts at both ends. The motor end covers at both ends of the motor are respectively fixed with two compression cylinders. The two ends of the motor shaft are respectively connected to the eccentric wheels of the two compression cylinders. The compression cylinder includes a cylinder, a piston and a connecting rod. The piston is installed in the cylinder. One end of the connecting rod is connected to the piston through a connecting rod pin, and the other end is connected to the eccentric wheel, which increases the number of cylinders to four. The gas production is four times that of the original single-cylinder gas supply, which greatly improves the gas production and work efficiency.

[0004] In the above patent, the number of cylinders is increased to four, thereby increasing the gas production. However, the dual-axis motor is used to drive the pistons at both ends of the dual shafts. At this time, the gas is generated from two directions, resulting in heat generation in two directions. The heat generation at both ends is difficult to balance, which will lead to different degrees of cylinder loss on both sides and cause unstable operation. In view of this, we propose a balancing mechanism for a four-cylinder piston compressor designed based on the dynamic balancing method. Utility Model Content

There are four compression mechanisms 3, and the ends of the driving rods 301 in the four compression mechanisms 3 away from the turntable 302 are respectively rotatably connected to one side of the inner wall of the casing 1 through bearings, and the spur gears four 306 in the three compression mechanisms 3 are respectively meshed with adjacent spur gears three 207, and the outer walls of the driving rods 301 in the three compression mechanisms 3 are respectively sleeved with bevel gears two 4, bevel gears three 5, and bevel gears four 6, which are respectively meshed with bevel gears one 204 in the three balancing mechanisms 2.

[0028] In this embodiment, after starting the motor 8, the driving rod 301 connected to it drives the turntable 302 to rotate, and causes the rocker arm 303 to rotate eccentrically through the pin, thereby driving the piston head 305 on the hinge block 304 to reciprocate along the inner wall of the cylinder port where it is located, and the spur gear four 306 follows the rotation and drives the spur gear three 207 to rotate, thereby causing the rotating rod 205 to drive the spur gear two 206 to rotate.

[0029] Embodiment 2

[0030] See also Figure 1-6On the basis of the first embodiment, the utility model provides a technical solution: preferably, a support 7 is installed on one side of the outer wall of the casing 1, and a motor 8 is installed on the support 7. The rotating end of the driving rod 301 in the other compression mechanism 3 continues to move through the outside of the casing 1 and is fixedly connected to the output shaft of the motor 8. Four cylinder ports are arranged on the cylinder body 9. The piston head 305 in each compression mechanism 3 is respectively slidably connected to the inner wall of each cylinder port. An intake pipe 10 and an exhaust pipe 11 are connected to the cylinder body 9. The ends of the intake pipe 10 and the exhaust pipe 11 away from the cylinder body 9 both penetrate the outside of the casing 1. An intake valve is installed on the intake pipe 10, and an exhaust valve is installed on the exhaust pipe 11.

[0031] In this embodiment, the four compression mechanisms 3 have the same structure, and the three balancing mechanisms 2 also have the same structure, which in turn causes the driving rod 301 where the bevel gear 2 4 is located to rotate, the bevel gear 3 5 drives the driving rod 301 to rotate, and the bevel gear 4 6 drives the driving rod 301 to rotate, so that the four piston heads 305 work in the corresponding cylinder ports at the same time, and the structural parts connected to the piston heads 305 are all made of the same structure and the same material, so that the movement balance of the cylinder ports in four directions can be guaranteed, so as to achieve the purpose of stable operation, and the four cylinder ports are compressed by the piston heads 305 in turn, and the output air flow pressure is stable.

[0032] Working principle: the casing 1 belongs to the outer shell of the air compressor, and the cylinder body 9 belongs to the main component of the four-cylinder compressor in the prior art. It has four cylinder ports that are compressed by the piston head 305 in turn, and the output air flow pressure is stable. The cylinder body 9 adopts an all-aluminum alloy structure, which is small in size, high in hardness, fast in heat dissipation, and long in service life. The support 7 is used to support and install the motor 8, so that the motor 8 can be fixed at a suitable height to match the installation of the drive rod 301. After starting the motor 8, the drive rod 301 connected to it drives the turntable 302 to rotate, and causes the rocker arm 303 to rotate eccentrically through the latch, thereby driving the hinge block 3 The piston head 305 on 04 reciprocates along the inner wall of the cylinder port, and the amount of air entering the cylinder body 9 is controlled by the intake valve. The piston head 305 reciprocates to compress the air and discharge the airflow into the exhaust pipe 11. The compressed airflow is stably transported to the outside or other equipment by adjusting the exhaust valve. The four cylinders are vertically distributed to each other to play a balancing role. When the driving rod 301 rotates, the spur gear four 306 rotates with it, and drives the spur gear three 207 to rotate through meshing, and then the rotating rod 205 drives the spur gear two 206 to rotate. At this time, the meshing spur gear one 203 The rotating shaft 202 is driven to rotate at the upper limit position of the support plate 201, and the bevel gear 1 204 and the meshing bevel gear 2 4 are driven to rotate, and then the driving rod 301 where the bevel gear 2 4 is located is driven to rotate, so that the piston head 305 on the rod makes a reciprocating motion in the corresponding cylinder port. Since the four compression mechanisms 3 have the same structure, the three balancing mechanisms 2 also have the same structure. Then, according to the above linkage mode, the bevel gear 3 5 is driven to rotate the driving rod 301, and the bevel gear 4 6 is driven to rotate the driving rod 301, so that the four piston heads 305 work in the corresponding cylinder ports at the same time. The gas is stably compressed in four vertical cylinder ports, and the structural parts connected to the piston head 305 are all made of the same structure and the same material, so the movement balance of the cylinder ports in four directions can be guaranteed to achieve the purpose of stable operation. A single motor 8 is used as a driving part to directly drive the four piston heads 305 to compress the gas through a linkage. During this period, the heat generated by the friction of the piston is concentrated in the cylinder body 9. The four cylinder ports are all connected to the cylinder body 9 and are discharged in an orderly manner through the exhaust pipe 11, so as to maintain the heat balance of the four cylinders and reduce the problem of different component wear in the four cylinders.
