Description

Technical Field

[0001] The present invention relates to the technical field of engines, and in particular to a compressed air type starting motor, a compressed air type starting system and an engine. Background Art

[0002] At present, most of the compressed air starter motors are vane type compressed air starter motors and turbine type compressed air starter motors. Due to the limitation of the transmission mode, the pressure resistance of vane type compressed air starter motors and turbine type compressed air starter motors is relatively low. The compressed air pressure allowed to enter the vane type compressed air starter motors and turbine type compressed air starter motors is mostly 1MPa. In order to increase the compressed air storage capacity and reduce the storage space, air compressors and air bottles with a pressure of 3MPa or 4MPa or even higher pressure are often used to supply air to the compressed air starter motor. Therefore, when the vane type compressed air starter motor and the turbine type compressed air starter motor use compressed air, it is necessary to equip the compressed air starter motor with a pressure reducing valve to reduce the pressure of the compressed air in the air bottle to ensure the safety of the compressed air starter motor. In addition, in order to prevent the compressed air starter motor from being damaged due to excessive compressed air pressure caused by damage to the pressure reducing valve and other reasons, a safety valve should be added to avoid damage to the compressed air starter motor caused by excessive compressed air pressure. Moreover, from the perspective of energy saving, the compressed air used by turbine-type compressed air starter motors and vane-type compressed air starter motors is compressed at high pressure and then decompressed for use, which invisibly causes energy and power waste.

[0034] The present invention provides a compressed air starter motor 100 .

[0035] In one embodiment, if Figures 1 to 4 As shown, the compressed air starter motor 100 includes a housing 10, a valve assembly 30 and a gear assembly 40. The housing 10 is provided with an air intake passage 11, a starting chamber 12, an air supply passage 13, a mounting chamber 14 and an air outlet pipe 15 which are independently arranged. The air intake passage 11 is connected with one end of the starting chamber 12, and the air intake passage 11 is also connected with the other end of the starting chamber 12 through a vent pipe 20 arranged outside the housing 10. The air supply passage 13, the mounting chamber 14 and the air outlet pipe 15 are connected in sequence. The two ends of the air supply passage 13 are an air intake port 131 and an air supply port 132 respectively. The air intake port 131 is located in the starting chamber 12 and is connected with the starting chamber 12. The air supply port 132 is located in the starting chamber 12 and is connected with the starting chamber 12. 32 is connected to the installation cavity 14; the valve assembly 30 includes a starting valve 31 and a solenoid valve 32, the starting valve 31 is slidably installed in the starting cavity 12 and closes the air inlet 131, and the solenoid valve 32 is installed on the ventilation pipe 20; the gear assembly 40 includes a first gear 41, a second gear 42 and an output gear 43, the first gear 41 and the second gear 42 are both rotatably installed in the installation cavity 14 and mesh with each other, the rotating shaft of the second gear 42 extends out of the installation cavity 14, and a synchronous gear 421 is installed at one end of the rotating shaft of the second gear 42 extending out of the installation cavity 14; the output gear 43 is located outside the housing 10 and is connected to the synchronous gear 421 through a transmission member 44;

[0036] The solenoid valve 32 is used to control the conduction of the ventilation pipe 20 and the opening of the starting valve 31, so that a part of the external compressed air entering the air intake channel 11 enters the starting chamber 12 through the ventilation pipe 20 to push the starting valve 31 to slide and open the air intake port 131, and the remaining part of the external compressed air enters the air supply channel 13 from the air intake port 131 through the starting valve 31 and the starting chamber 12 and is blown into the installation chamber 14 from the air outlet to push the first gear 41 and the second gear 42 to rotate.

[0037] The air intake channel 11 is located at the left end of the starting chamber 12 and is connected to the starting chamber 12. The air intake channel 11 is also connected to the right end of the starting chamber 12 through the ventilation pipe 20. The air intake port 131 of the air supply channel 13 is located at the front side of the starting chamber 12 and is connected to the starting chamber 12. The air supply port 132 of the air supply channel 13 is located at the front side of the mounting chamber 14 and is connected to the mounting chamber 14. The first gear 41 and the second gear 42 both extend in the left and right directions. The movement direction of the external compressed air blown out from the air supply port 132 is from front to back, thereby driving the teeth of the first gear 41 and the second gear 42 to rotate.

[0038] When the compressed air starter motor 100 of the present invention is in use, the electromagnetic valve 32 is opened to conduct the vent pipe 20, so that a part of the external compressed air entering the air inlet channel 11 enters the start chamber 12 through the vent pipe 20, pushes the start valve 31 to slide to the left and opens the air inlet 131, and then the electromagnetic valve 32 opens the start valve 31, so that the other part enters the air supply channel 13 from the air inlet 131 through the start valve 31 and the start chamber 12 and blows into the installation chamber 14 from the air outlet, so as to push the first gear 41 and the second gear 42 to rotate, and convert the energy of the compressed air into the mechanical energy of the first gear 41 and the second gear 42 to rotate, and the synchronous gear 421 of the second gear 42 drives the output gear 43 to rotate through the transmission member 44, and the output gear 43 is used to connect with the power machinery, and the output gear 43 drives the power machinery to start, thereby realizing the conversion of the energy of the compressed air into the mechanical energy of the power machinery to start. Specifically, the power machinery can be an engine. After use, the solenoid valve 32 interrupts the ventilation pipe 20 and closes the starting valve 31. The compressed air in the air intake channel 11 enters the left end of the starting chamber 12 to push the starting valve 31 to slide rightward to close the air intake port 131, thereby resetting the starting valve 31.

[0039] The present invention converts the energy of external compressed air into mechanical energy for the rotation of the first gear 41 and the second gear 42 by arranging an air intake channel 11, a starting chamber 12, an air supply channel 13, an installation chamber 14, an air outlet pipe 15, a vent pipe 20 and a first gear 41 and a second gear 42 that mesh with each other. The structural design is reasonable, and the gear transmission has the advantages of reliable operation and high pressure resistance, thereby improving the pressure resistance of the compressed air starter motor 100. Therefore, compressed air with a pressure of 1MPa to 5MPa can be used. The application range is wide, and the compressed air starter motor 100 has high flexibility in use. For air compressors and air bottles with an internal compressed air pressure of less than 5MPa, there is no need to be equipped with a pressure reducing valve for reducing the air pressure and a safety valve to ensure that the internal air pressure of the compressed air starter motor 100 is appropriate, thereby reducing the failure points and improving the reliability of the compressed air starter motor 100. In addition, there is no need to pressurize and store the external compressed air and then decompress it for use, thereby playing a role in energy saving. In addition, the external compressed air will contain impurities and rust particles formed by moisture. The impurities and rust particles will enter the installation cavity and adhere to the first gear 41 and the second gear 42. When the meshing first gear 41 and the second gear 42 rotate, friction and vibration will be generated, causing the impurities and rust particles attached to the first gear 41 and the second gear 42 to fall off, thereby avoiding damage to the first gear 41 and the second gear 42 due to impurities and rust particles, thereby improving the reliability and safety of the compressed air starter motor 100.

[0040] In one embodiment, if Figure 2 and Figure 4 As shown, the compressed air starter motor 100 further includes a cylinder 50, the vent pipe 20 includes a first air pipe 21 and a second air pipe 22, the air intake passage 11 and the cylinder 50 are connected through the first air pipe 21, the piston rod 51 of the cylinder 50 is connected to the output gear 43 and is used to push and pull the output gear 43 away from or close to the housing 10, the solenoid valve 32 is installed on the first air pipe 21, and the starting chamber 12 is connected to the cylinder 50 through the second air pipe 22. When the solenoid valve 32 conducts the first air pipe 21, external compressed air enters the cylinder 50, and pushes the piston rod 51 to the right to push the output gear 43 to move to the right and mesh with the gear of the power machinery, so as to realize the connection between the output gear 43 and the power machinery. Specifically, the gear of the power machinery can be a flywheel of the engine. After the solenoid valve 32 closes the first air pipe 21, the cylinder 50 pulls the output gear 43 back to the left to disconnect from the power machine, ensuring that the output gear 43 is connected to the power machine only when the compressed air starter motor 100 is running, avoiding damage to the output gear 43 caused by the gear connected to the power machine for a long time, thereby improving the reliability of the compressed air starter motor 100. The connection between the intake channel 11 and the starting chamber 12 is also achieved by setting the second air pipe 22, and the structural design is more reasonable.

[0041] Furthermore, an air hole 53 is provided on the cylinder body 52 of the cylinder 50, and the second air pipe 22 is connected to the air hole 53. The two ends of the piston rod 51 of the cylinder 50 are respectively a free end 512 and a mounting end 511. The free end 512 is connected to the output gear 43, and the mounting end 511 is installed in the cylinder body 52 of the cylinder 50 and divides the cylinder body 52 into an inflation part 521 and a vacuum part 522. The first air pipe 21 is connected to the inflation part 521. When external compressed air enters the inflation part 521 without passing through the first air pipe 21, the air hole 53 is located in the vacuum part 522 and is connected to the vacuum part 522. When external compressed air enters the inflation part 521 through the first air pipe 21 and pushes the mounting end 511 to slide to a position in the cylinder body 52 close to one end of the output gear 43, the inflation part 521 is connected to the air hole 53.

[0042] like Figure 4 and Figure 5 As shown, the left end of the piston rod 51 is the mounting end 511, and the right end is the free end 512. The left part of the cylinder body 52 is the inflation part 521, and the right part is the vacuum part 522. External compressed air enters the inflation part 521 through the first air pipe 21 to push the mounting end 511 to slide to the right. When the mounting end 511 slides to the rightmost end, the air hole 53 is connected with the inflation part 521. At this time, the output gear 43 is connected with the power machinery, and the first air pipe 21 is connected with the second air pipe 22. The external compressed air entering the inflation part 521 enters the starting chamber 12 through the second air pipe 22 to push the starting valve 31 to slide and open the air inlet 131, so as to ensure that the output gear 43 starts to rotate only after the output gear 43 is meshed with the gear of the power machinery, thereby improving the reliability of the compressed air starter motor 100.

[0043] In one embodiment, the transmission member 44 is a sleeve 44a, which is installed in the housing 10. The sleeve 44a has a first inner tooth pattern portion 441 and a second inner tooth pattern portion 442 arranged at intervals. The first inner tooth pattern portion 441 is meshed with the synchronous gear 421, and an outer tooth pattern for meshing with the second inner tooth pattern portion 442 is provided on the rotating shaft of the output gear 43. The first inner tooth pattern portion 441 is meshed with the synchronous gear 421, and the synchronous gear 421 drives the sleeve 44a to rotate. After the output gear 43 is pushed by the piston rod 51, the outer tooth pattern on the rotating shaft is meshed with the second inner tooth pattern portion 442, and the sleeve 44a drives the rotating shaft of the output gear 43 to rotate, so as to realize the transmission of torque, and the structural design is more reasonable.

[0044] Furthermore, the second inner tooth pattern portion 442 and the outer tooth pattern portion are both helical tooth patterns, so that the output gear 43 moves in a direction away from the synchronous gear 421 when the sleeve 44a rotates; a blocking portion is provided at one end of the second inner tooth pattern portion 442 away from the synchronous gear, and the blocking portion is used to abut against the rotating shaft of the output gear 43. The second inner tooth pattern portion 442 and the outer tooth pattern portion are both helical tooth patterns, and the helical tooth patterns can guide the movement of the output gear 43, so that the rotating shaft of the output gear 43 can move along the helical tooth patterns while performing translational movement and rotational movement during the movement, so that the output gear 43 can stably mesh with the gear of the power machinery, thereby improving the reliability of the compressed air starter motor 100. In addition, by providing a blocking portion to limit the rotating shaft of the output gear 43, the rotating shaft of the output gear 43 is prevented from being displaced when the sleeve 44a rotates, thereby further improving the reliability of the compressed air starter motor 100. In addition, the helical tooth transmission has the advantages of good meshing performance, smoother transmission, and higher transmission efficiency. The helical tooth transmission has a large overlap. The increase in overlap improves the bearing capacity of the rotating shaft of the sleeve 44a and the output gear 43, thereby extending the service life of the sleeve 44a and the output gear 43.

[0045] In one embodiment, if Figure 4 As shown, the starting valve 31 includes a valve 311 and a valve body 312, the valve body 312 has a through hole 3121 communicating with the starting chamber 12, the valve 311 is installed in the through hole 3121, and the solenoid valve 32 is used to control the valve 311 to open or close the through hole 3121. By providing the valve 311 that can open the through hole 3121 to enable external compressed air to enter the air delivery channel 13 from the air inlet 131 through the starting valve 31 and the starting chamber 12, the structural design is more reasonable.

[0046] In one embodiment, if Figure 1 and Figure 2 As shown, the two ends of the air outlet pipe 15 are respectively a connecting end and an air outlet end 151, the connecting end is connected to the installation cavity 14, and a muffler 152 is installed at the air outlet end 151. By arranging the muffler 152 at the air outlet end 151, the noise generated by the compressed air starter motor 100 is reduced, and the reliability of the compressed air starter motor 100 is improved.

[0047] In one embodiment, two first mounting seats 141 and two second mounting seats 142 are provided in the mounting cavity 14, and both ends of the first gear 41 are respectively mounted on the two first mounting seats 141 through two first rotating bearings 1411, and both ends of the second gear 42 are respectively mounted on the two second mounting seats 142 through two second rotating bearings 1421, and the first gear 41 and the second gear 42 are arranged side by side. Both ends of the first gear 41 are respectively mounted on the two first mounting seats 141 through two first rotating bearings 1411, and both ends of the second gear 42 are respectively mounted on the two second mounting seats 142 through two second rotating bearings 1421, so that the first gear 41 and the second gear 42 can be rotatably mounted in the mounting cavity 14, and the rotation flexibility of the first gear 41 and the second gear 42 can be improved.

[0048] The present invention also proposes a compressed air starting system, including an air compressor, a first pipeline, a filter, and a second pipeline connected in sequence. The compressed air starting system also includes the above-mentioned compressed air starting motor 100. The second pipeline is connected to the air intake channel 11. The compressed air generated by the air compressor passes through the first pipeline to the filter for filtration and then enters the air intake channel 11 through the second pipeline, thereby supplying air to the compressed air starting motor 100. There is no need to set a pressure reducing valve and a safety valve, and the structural design is simpler.

Since the compressed air starting system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0049] The present invention also provides an engine, including a flywheel and the above-mentioned compressed air starting system, wherein the output gear 43 is used to mesh with the flywheel. The piston rod 51 pushes the rotating shaft of the output gear 43 to move rightward so that the output gear 43 meshes with the flywheel, and the output gear 43 rotates to drive the flywheel to rotate, thereby starting the entire engine. After the start is completed, the piston rod 51 pulls back the output gear 43 to disengage the output gear 43 from the flywheel.
