The drive rod 15 can also drive the adjustment unit, which can realize the circulation of air inside the chamber 1 and realize the rapid adjustment of the temperature and humidity inside the chamber 1, greatly improving the test efficiency.
[0027] In one embodiment of this utility model, please refer to Figure 3 and Figure 5 The adjustment unit includes: a connecting box 8, a support pipe 9, an air blowing pipe 10, an air supply pipe 13, a transmission rod 16, a gearbox 17, an air guide box 18, a humidifier 26, a regulator 27, a branch pipe 28, a fan 29, and a connecting pipe 30. The connecting box 8 is fixedly installed inside the housing 1. Support pipes 9 are symmetrically arranged on both sides of the support plate 5. The support pipes 9 are fixedly connected to the connecting box 8. Several air blowing pipes 10 are fixedly installed on the pipe wall near the support plate 5. The connecting box 8 is connected to the air guide box 18 located inside the control box 4 through the air supply pipe 13. A gearbox 17 is fixedly installed on the outside of the air guide box 18. One end of the gearbox 17 is connected to the air guide box 18 located inside the control box 4. A fan 29 is fixedly connected inside the box 18, and the other end is connected to a transmission rod 16 via a first belt. The transmission rod 16 is rotatably connected to the control box 4. The transmission rod 16 is connected to the drive rod 15 via a second belt. A connecting pipe 30 is fixedly installed on the side of the air box 18 away from the air supply pipe 13. The other end of the connecting pipe 30 is connected to a regulator 27 for controlling the air temperature. The input end of the regulator 27 is connected to the box 1 via an air intake pipe. A humidifier 26 connected to the control box 4 is installed outside the connecting pipe 30. The output end of the humidifier 26 is connected to the connecting pipe 30 via a branch pipe 28. A solenoid valve is fixedly installed inside the branch pipe 28.
[0028] In this embodiment, the regulator 27 is equipped with a cooler and a heater. The cooler includes a compressor, a condenser, a shut-off valve, and an evaporator. The refrigeration cycle adopts a reverse Carnot cycle, which consists of two isothermal processes and two adiabatic processes. The refrigerant is adiabatically compressed to a higher pressure by the compressor, consuming work and raising the exhaust temperature. Then, the refrigerant isothermally exchanges heat with the surrounding medium through the condenser, transferring heat to the surrounding medium. Afterward, the refrigerant adiabatically expands through the shut-off valve, doing work. Finally, the refrigerant isothermally absorbs heat from the object with a higher temperature through the evaporator, lowering the temperature of the object being cooled. This cycle repeats continuously to achieve the purpose of cooling. The heater is a high-quality nickel-chromium wire heater. The first belt component includes a first pulley fixedly disposed at the input end of the gearbox 17 and outside the transmission rod 16, and a first belt for connecting the first pulley. The second belt component includes a second pulley fixedly disposed outside the transmission rod 16 and the drive rod 15. The second belt, used to connect the second pulley, is adjusted by a drive rod 15, which drives the transmission rod 16 to rotate via the second pulley and the second belt. The transmission rod 16, in conjunction with the gearbox 17, rotates the fan 29. While ensuring the fan 29's speed, the rotation speed of the support plate 5 is reduced, allowing the fixed bearing to undergo more comprehensive temperature resistance testing. Air inside the chamber 1 enters the regulator 27 through the suction pipe. The regulator 27 adjusts the air temperature as needed. Simultaneously, the humidifier 26 controls the air humidity through the branch pipe 28, thus completing the adjustment of air temperature and humidity. Subsequently, the treated air is sent into the air guide box 18 and enters the connecting box 8 along the air supply pipe 13. It is then discharged from the blowing pipe 10 on the support pipe 9, exiting synchronously from all four sides. This not only ensures the uniformity of temperature and humidity distribution but also greatly improves adjustment and maintains the comprehensiveness of the test.
[0029] In one embodiment of this utility model, a temperature sensor and a humidity sensor connected to a controller are also fixedly installed inside the housing 1. The controller is used to control the regulator 27 and, together with the temperature sensor and humidity sensor, complete the adjustment of air temperature and humidity.
[0030] This non-standard high and low temperature fatigue durability test chamber uses an electric push rod 22 to drive the control frame 21 for lifting and lowering. The control frame 21 drives the two movable frames 19 on both sides to move synchronously in opposite directions through the connecting rod 20. The movable frames 19 drive the support columns 6 to move, adjusting the distance between the two support columns 6, so that the support columns 6 can support bearings of different sizes. Subsequently, the second motor 23 rotates the threaded rod 24, which enables the lifting frame 25 to rise and fall. The lifting frame 25 drives the clamping column 7 to rise and fall synchronously. The clamping column 7, together with the two support columns 6, locks the bearing. The first motor 14 drives the drive rod 15 to rotate, which in turn drives the drive gear 11 to rotate. The drive gear 11, together with the driven gear 12, rotates the support plate 5, thereby achieving the rotation of the fixed bearing, ensuring the comprehensiveness of the bearing test. 5. The transmission rod 16 is driven to rotate by the second pulley and the second belt. The transmission rod 16, in conjunction with the gearbox 17, drives the fan 29 to rotate. While ensuring the speed of the fan 29, the rotation speed of the support plate 5 is reduced, so that the fixed bearing can be subjected to more comprehensive temperature resistance testing. The air inside the chamber 1 enters the inside of the regulator 27 through the air intake pipe. The regulator 27 adjusts the air temperature according to the requirements. At the same time, the humidifier 26 can control the air humidity through the branch pipe 28, thereby completing the adjustment of air temperature and humidity. Subsequently, the treated air is sent into the inside of the air guide box 18 and enters the inside of the connecting box 8 along the air supply pipe 13. It is discharged from the blowing pipe 10 set on the support pipe 9 and discharged synchronously from all four sides. This not only ensures the uniformity of temperature and humidity distribution, but also greatly improves the adjustment and maintains the comprehensiveness of the test.
[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
