Abstract
Description
Technical Field
[0001] This utility model relates to an air-cooling device for a geared pneumatic motor, and pertains to the field of pneumatic device technology. Background Technology
[0002] During operation, the pressure and temperature of compressed air decrease as it expands to perform work in a geared pneumatic motor. The low-temperature compressed air carries away the heat inside the motor. However, the reduction gear and braking device require cooling as their temperatures rise during operation. Existing cooling systems typically use oil pumps for circulating cooling, which is energy-intensive and structurally complex. Therefore, further improvements to the cooling system for geared pneumatic motors are needed. Summary of the Invention
[0003] The purpose of this invention is to provide an air-cooling device for a geared pneumatic motor for cooling and temperature reduction.
[0004] In view of the above-mentioned technical problems, this utility model provides an air-cooling device for a geared pneumatic motor, including a pneumatic motor, a buffer tank, a gearbox, a braking device, a brake cooling pipe, and a gearbox cooler. The exhaust pipe of the pneumatic motor is connected to the buffer tank, and a braking device is provided between the pneumatic motor and the gearbox. A cooling pipe is connected to the buffer tank, and a control valve is provided on the cooling pipe. The control valve controls the opening and closing of the brake cooling pipe. The control valve also controls the opening and closing of the gearbox cooling pipe, and a cooler is provided on the gearbox cooling pipe, which is located at the bottom of the gearbox.
[0005] Preferably, the cooler performs jet oil spraying cooling, and the cooler is equipped with several jet oil spray pipes.
[0006] Preferably, an exhaust filter is provided on the top of the gearbox.
[0007] Preferably, the buffer tank is equipped with a pressure venting valve.
[0008] Based on the above technical solution, this utility model has at least one of the following beneficial effects: This utility model discloses an air-cooling device for a geared pneumatic motor, which uses jet cooling to cool the brake device. The device has a simple structure and a significant cooling effect. The lubricating oil is circulated and cooled by a cooler located at the bottom of the gearbox, making the structure simple and practical. The cooler uses venturi tube jet oil spray for lubrication and cooling, resulting in high lubrication efficiency and significant cooling effect.
[0009] The buffer tank is equipped with a pressure exhaust valve. The pneumatic motor works by the pressure difference between the intake and exhaust. When the pressure inside the buffer tank exceeds the set value, the pressure exhaust valve opens to prevent air blockage and improve the working efficiency of the pneumatic motor.

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0013] like Figure 1 As shown, an air-cooling device for a geared pneumatic motor includes a pneumatic motor 1, a buffer tank 3, a gearbox 4, a brake device 5, a brake cooling pipe 9, and a gearbox cooling pipe 10. The exhaust pipe 2 of the pneumatic motor 1 is connected to the buffer tank 3, and the brake device 5 is installed between the pneumatic motor 1 and the gearbox 4. A cooling pipe 7 is connected to the buffer tank 3, and a control valve 8 is installed on the cooling pipe 7. The control valve 8 controls the opening and closing of the brake cooling pipe 9. Pressurized air discharged from the pneumatic motor 1 enters the buffer tank 3, the control valve 8 opens, and the pressurized air sprays through the brake cooling pipe 9 to cool the brake device 5. The control valve 8 controls the opening and closing of the gearbox cooling pipe 10, and a cooler 11 is installed on the gearbox cooling pipe 10. The cooler 11 is located at the bottom of the gearbox 4, and it cools the lubricating oil at the bottom of the gearbox 4, thus removing heat from inside the gearbox 4. The cooler 11 performs jet oil cooling. Several jet oil spray pipes 12 are installed on the cooler 11. The lubricating oil sprayed from the oil spray pipes 12 lubricates the moving parts inside the gearbox 4. An exhaust filter 13 is installed on the top of the gearbox 4. Oil-containing pressurized air inside the gearbox 4 enters the exhaust filter 13 for filtration before being discharged. A pressure exhaust valve 6 is installed on the buffer tank 3. The pneumatic motor 1 operates based on the pressure difference between the intake and exhaust. If the pressure inside the buffer tank 3 exceeds a set value, the pressure exhaust valve 6 opens to prevent air blockage, which would affect the working efficiency of the pneumatic motor 1.
[0014] This concludes the description of the embodiments of this utility model.
[0015] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
