Piston pneumatic motors can be used for refrigeration, engines, gas transportation, chemical processes, machinery manufacturing, aquaculture, medical treatment, and almost every place where compressed gas needs to be transported or used. At present, the commonly used piston pneumatic motors are mainly piston-type air piston pneumatic motors and screw-type air piston pneumatic motors. Although these two types of piston pneumatic motors have their own advantages, they also have certain shortcomings. For example, the piston-type air piston pneumatic motor mainly uses the rotation of the crankshaft to output mechanical energy to the outside, and the reciprocating linear motion of the piston compresses the gas in the cylinder. The friction noise of the bearing is large, the stability is poor, and the vibration is large; the rotor of the screw-type air piston pneumatic motor meshes and rubs in the cylinder, the rotation speed is fast, and the heat generation is large. Not only does it require the material to have high wear resistance, but it also requires a large amount of cooling lubricating oil when in use, and the difficulty of repair and maintenance is relatively large.

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0030] like Figure 1-Figure 6 As shown, a horizontally opposed piston pneumatic motor is provided, comprising a pneumatic motor housing 10, a cam main shaft 1, a first bearing 2 sleeved on the cam main shaft 1, a double eccentric cam 3 sleeved on the first bearing 2, a second bearing 4 sleeved on the double eccentric cam 3 and a guide slider 5, the guide slider 5 is provided with a horizontally opposed piston assembly 6 and a cylinder 7, the cam main shaft 1 is provided with a gas distribution valve 11, the gas distribution valve 11 is provided with a gas distribution valve sleeve 8, the pneumatic motor housing 10 is provided with a high-pressure gas input to drive the piston assembly 6 in the cylinder 7 The air inlet 12 reciprocates upward and the air outlet 1003 is used to discharge the high-pressure gas. When the high-pressure gas enters the gas distribution valve sleeve 8 and the gas distribution valve 11 through the air inlet 12, the high-pressure gas supplies gas to the cylinder 7 through the gas distribution valve 11, so that the gas distribution valve sleeve 8 rotates and the high-pressure gas expands and does work in the cylinder 7, thereby pushing the piston assembly 6 to reciprocate and drive the guide slider 5, the double eccentric cam 3 and the cam main shaft 1 to rotate. The compressed high-pressure gas is discharged from the air outlet 1003 to realize the output of mechanical energy to complete a reciprocating cycle.

[0031] Specifically, when high-pressure gas enters the gas distribution valve sleeve 8 and the gas distribution valve 11 through the air inlet 12 on the pneumatic motor housing 10, the high-pressure gas is introduced into the cylinder 7. Under the control of the gas distribution valve sleeve 8, the gas expands in the cylinder 7, pushing the piston assembly 6 to reciprocate. The movement of the piston assembly 6 is transmitted to the double eccentric cam 3 through the guide slider 5, and the double eccentric cam 3 then drives the cam main shaft 1 to rotate. This series of actions forms a complete reciprocating cycle. In this way, the pneumatic motor converts gas pressure into mechanical energy and outputs it as rotational power. When When the cam main shaft 1 rotates, the first bearing 2 mounted on the double eccentric cam 3 drives the double eccentric cam 3, and the double eccentric cam 3 drives the second bearing 4 to make corresponding circular motion in the guide slider 5. The symmetrical connecting rod 13 connected to the guide slider 5 drives the piston assembly 6 screwed thereto to make reciprocating linear motion in the same plane and on the same center line. After completing the work, the high-pressure gas in the cylinder 7 is discharged through the outlet 1003. The above process is continuously circulated, converting the relatively high-pressure gas into the rotation of the motor output shaft, continuously outputting mechanical energy, and then driving the external mechanical device.

[0032] By using a double eccentric cam, smoother reciprocating motion can be achieved, friction and wear can be reduced, and overall mechanical efficiency can be increased; the horizontally opposed piston assembly is beneficial to the balance of the machine body, reduces vibration, and can also better disperse heat, helping to improve the stability and service life of the system; the design of the air valve makes the control of the airflow more precise, effectively improving the energy utilization efficiency and response speed, while also simplifying the complexity of the pneumatic system.

[0033] Further, if Figure 1-Figure 8 As shown, more than one guide slider 5 is provided, and the more than one guide slider 5 is arranged on the cam main shaft 1 at a 90° horizontal angle.

[0034] Specifically, in this embodiment, two guide sliders 5 are provided, and at least two guide sliders 5 move back and forth in mutually horizontal directions under the action of the piston assembly 6. The length direction of one guide slider 5 is set horizontally left and right, and the length direction of the other guide slider 5 is set horizontally front and back. Each guide slider 5 is grouped and transmission-connected with the piston assembly 6 and the cylinder 7; thereby realizing piston pneumatic motors with various numbers of cylinders: 1 cylinder, 2 cylinders, 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, 7 cylinders, 7 cylinders, 9 cylinders, 10 cylinders, 11 cylinders, or 12 cylinders, etc.

[0035] Further, if Figure 1-Figure 8 As shown, a connecting rod 13 is provided on the guide slider 5 , the piston assembly 6 and the cylinder 7 are horizontally opposed to the connecting rod 13 , and the piston assembly 6 is located on the connecting rod 13 .

[0036] Specifically, installing the piston assembly 6 on the connecting rod 13 directly opposite to the cylinder 7 helps to reduce the intermediate links in the structure, thereby improving the overall mechanical efficiency and response speed.

[0037] Further, if Figure 1-Figure 8 and Fig.11 As shown, more than one connecting rod 13 is provided, and the more than one connecting rod 13 is extended relatively outward on the guide slider 5.

[0038] Specifically, by providing more than one connecting rod 13 on the guide slider 5 and extending the connecting rod 13 outward, multi-point support and power transmission can be achieved. This configuration further enhances the stability of the mechanism and the uniformity of power distribution.

[0039] Further, if Figure 1-Figure 6 and Figure 8As shown, the symmetrical guide slider 5 reciprocates simultaneously in the same plane of the pneumatic motor housing 10 and the piston assembly 6 on the cylinder 7; the piston assembly 6 is symmetrically arranged on the connecting rod 13 as a positioning guide, and the piston assembly 6 includes a piston ring 601, a leather cup 602 and a leather cup pressure cover 603, the piston ring 601 is sleeved on the circumference of the end of the connecting rod 13, and the leather cup 602 and the leather cup pressure cover 603 are arranged on the end of the connecting rod 13.

[0040] Specifically, the piston assembly 6 is symmetrically arranged on the connecting rod 13, ensuring the precise positioning and guiding of the piston, and improving the efficiency and accuracy of the movement; the configuration of the piston ring 601, the leather cup 602 and the leather cup gland 603 helps to form a seal, reduce gas leakage and improve compression efficiency.

[0041] Further, if Figure 1 and Figure 2 As shown, an exhaust muffler 16 is provided on the air outlet 1003, and the high-pressure gas is discharged from the air outlet 1003 and the exhaust muffler 16; a through hole 801 connected to the air inlet 12 is provided on the air distribution valve sleeve 8, and the high-pressure gas enters the air distribution valve 11 from the through hole 801, and the air holes 1002 are evenly distributed inside the pneumatic motor housing 10, and the air distribution valve 11 is connected with the cylinder 7 through the air holes 1002.

[0042] Specifically, the exhaust muffler 16 is installed to reduce the noise generated during operation and improve the comfort of the working environment; the setting of the through hole 801 ensures that the high-pressure gas can smoothly enter the gas distribution valve 11 from the air inlet 12, and the air hole 1002 allows the gas distribution valve 11 to accurately control the amount of gas entering the cylinder 7. The uniform distribution of the air holes 1002 in the pneumatic motor housing 10 helps to balance the internal pressure, avoid local airflow that is too fast or too slow, and supply air to each cylinder 7 in sequence.

[0043] Further, if Figure 1 and Figure 2 As shown, the cylinder 7 is provided with a connecting groove 701 which is in communication with the air hole 1002 .

[0044] Specifically, the setting of the connecting groove 701 enables the high-pressure gas coming out of the gas distribution valve 11 to be more evenly distributed to the entire working surface of the cylinder 7. This uniform gas distribution helps to improve the working efficiency and reaction speed of the cylinder. The uniform airflow helps to reduce the internal friction and wear caused by uneven airflow, thereby extending the service life of the pneumatic motor.

[0045] Further, if Figure 8 and Fig.11As shown, the double eccentric cam 3 includes a connecting hole 301 that is circumferentially matched with the outer diameter of the first bearing 2; the double eccentric cam 3 includes an eccentric wheel periphery 302, and the inner diameter of the second bearing 4 is sleeved on the eccentric wheel periphery 302; an inner cavity 501 is provided on the guide slider 5, and the outer diameter of the second bearing 4 is circumferentially matched with the inner cavity 501.

[0046] Specifically, the connecting hole 301 is circumferentially matched with the outer diameter of the first bearing 2, ensuring the stability and precise alignment of the cam on the shaft, reducing vibration and friction during movement, and the precise matching also helps to improve the efficiency of power transmission because energy loss is reduced in lower friction; the inner diameter of the second bearing 4 is mounted on the eccentric wheel periphery 302. This design allows the double eccentric cam 3 to rotate smoothly while supporting high load transmission, which is beneficial to dispersing the force generated by the rotation of the double eccentric cam 3, maintaining the balance of the system and reducing wear; the outer diameter of the second bearing 4 is circumferentially matched with the inner cavity 501 on the guide slider 5, which provides stable and precise axial support for the movement of the guide slider 5, ensuring the smooth movement and good alignment of the guide slider 5, and contributing to the accuracy and response speed of the overall mechanism.

[0047] Further, if Figure 8 and Fig.10 As shown, the cam main shaft 1 includes an output end 101 and a connecting end 102. The central axis of the output end 101 coincides with the central axis of the cam main shaft 1, and the central axis of the connecting end 102 is eccentrically arranged with the central axis of the cam main shaft 1. The cam main shaft 1 is also provided with a third bearing 14 and a cam balance block 15.

[0048] Specifically, the central axis of the output end 101 coincides with the central axis of the cam main shaft 1. This design ensures that the force and motion transmission at the output end is direct and without deviation, which is suitable for applications requiring precise control and direct power output, and ensures stable power transmission; the central axis of the connecting end 102 is eccentric relative to the central axis of the cam main shaft 1. This eccentric setting is the core mechanism for converting rotational motion into reciprocating linear motion; the greater the eccentricity, the greater the amplitude of the reciprocating motion generated, so that this design can be adjusted as needed to adapt to different compression requirements; the third bearing 14 is installed on the cam main shaft 1 to support the bearing load and reduce friction during movement, thereby ensuring the smoothness and accuracy of the main shaft operation. The addition of the third bearing 14 helps to disperse the additional load generated by the eccentric connecting end 102, prevent axial displacement and reduce wear; the cam balance block 15 is used to balance the asymmetric load caused by the eccentricity of the cam, improve the overall mechanical balance, and can significantly reduce vibration, reduce noise, and extend mechanical life.

[0049] Further, if Figure 8 and Fig.10As shown, a plurality of first bearings 2 are provided, and the plurality of first bearings 2 are sleeved on the connecting end 102 at intervals, and a gasket 9 is provided between each first bearing 2 .

[0050] Specifically, the use of multiple first bearings 2 can more evenly disperse the load and stress generated by eccentric motion, and can improve the overall stability of the system, especially under high-speed operation and high-load conditions, and help maintain the correct alignment and running smoothness of the cam shaft 1; placing gaskets 9 between each first bearing 2 can accurately adjust the distance between the bearings, and appropriate spacing helps to optimize the load distribution of the bearings and reduce friction and wear.
