[0051] In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0052] As Figures 1 to 9 shown, the embodiments of the present application provide a lubrication system test device, which comprises a rack 1, a first adjusting assembly 2, a second adjusting assembly 3, a driving assembly 4 and a lubrication system 5. The first adjusting assembly 2 is installed on the rack 1. The second adjusting assembly 3 is installed on the first adjusting assembly 2 and can rotate around the first direction under the driving of the first adjusting assembly 2. The driving assembly 4 is installed on the second adjusting assembly 3 and can rotate around the second direction under the driving of the second adjusting assembly 3. The lubrication system 5 is installed on the driving assembly 4.

[0053] It is to be noted here that the first direction above and below refers to the bidirectional direction of the rotation axis 221 line of the output end of the first adjusting assembly 2, specifically the X-axis as shown in Figure 1 The second direction above and below refers to the bidirectional direction of the rotation axis 221 line of the output end of the second adjusting assembly 3, specifically the Y-axis as shown in Figure 1 .

[0054] Specifically, as Figure 2As shown, when the lubricating system 5 needs to be inclined forward, the tester drives the second adjusting assembly 3 to rotate clockwise around the first direction through the first adjusting assembly 2. Under the drive of the second adjusting assembly 3, the lubricating system 5 rotates around the first direction towards the ground. That is, the lubricating system 5 is inclined forward. When the lubricating system 5 needs to be inclined backward, the tester drives the second adjusting assembly 3 to rotate counterclockwise around the first direction through the first adjusting assembly 2. Under the drive of the second adjusting assembly 3, the lubricating system 5 rotates around the first direction away from the ground. That is, the lubricating system 5 is inclined backward. As shown in Figure 3 As shown, when the lubricating system 5 needs to be inclined left, the tester drives the lubricating system 5 to rotate counterclockwise around the second direction through the second adjusting assembly 3. That is, the lubricating system 5 is inclined left. When the lubricating system 5 needs to be inclined right, the tester drives the lubricating system 5 to rotate clockwise around the second direction through the second adjusting assembly 3. That is, the lubricating system 5 is inclined right.

[0055] The lubricating system test device provided in the present application adopts the first adjusting assembly 2, which can make the lubricating system 5 inclined forward or backward. The second adjusting assembly 3 can make the lubricating system 5 inclined left or right. Under the cooperation of the first adjusting assembly 2 and the second adjusting assembly 3, the lubricating system 5 can rotate around the first direction and the second direction at the same time, which can simulate the working condition of the lubricating system 5. Moreover, the posture of the lubricating system 5 can be adjusted according to the test requirement, which has a wide application range, good versatility, is convenient for the tester to study the lubricating condition of the lubricating system 5 under different working conditions, and is convenient for test. The driving assembly 4 can adjust the rotating speed of the internal gear structure of the lubricating system 5 according to the test requirement, which can also be used to simulate the working condition of the lubricating system 5, which helps to further expand the application range and is convenient for test.

[0056] In an embodiment of the present application, please refer to Figures 1 to 9 The first adjusting assembly 2 includes a first speed reducer 21, a rotating frame 22 and a clamping piece 23. The first speed reducer 21 is installed on the rack 1. The rotating frame 22 is installed on the rack 1 and can rotate around the first direction under the drive of the first speed reducer 21. The clamping piece 23 is installed on the end of the rotating frame 22 away from the first speed reducer 21 and can clamp the rotating frame 22.

[0057] Specifically, when the lubricating system 5 needs to be inclined forward, the tester drives the rotating frame 22 and the second adjusting assembly 3 to rotate clockwise around the first direction through the first speed reducer 21, so as to make the lubricating system 5 inclined forward until the lubricating system 5 is inclined forward to the target angle. The tester locks the rotating frame 22 through the clamping piece 23. When the lubricating system 5 needs to be inclined backward, the tester drives the rotating frame 22 and the second adjusting assembly 3 to rotate counterclockwise around the first direction through the first speed reducer 21, so as to make the lubricating system 5 inclined backward until the lubricating system 5 is inclined backward to the target angle. The tester locks the rotating frame 22 through the clamping piece 23.

[0058] In this way, the first speed reducer 21 is adopted, the test personnel can drive the rotating frame 22 to rotate around the first direction, so that the lubricating system 5 can be tested to tilt forward or tilt backward, the test personnel can adjust the posture of the lubricating system 5, the working condition of the lubricating system 5 can be simulated, and the test is facilitated. The rotating frame 22 is adopted, the second adjusting assembly 3 can be conveniently installed. Moreover, the lubricating system 5 can be driven to rotate around the first direction through the second adjusting assembly 3. The clamping piece 23 is adopted, after the lubricating system 5 is rotated to the target angle, the rotating frame 22 can be locked, the lubricating system 5 is prevented from rotating relative to the rack 1 during the test to cause errors in the test, and the test is facilitated.

[0059] Optionally, the first speed reducer 21 is a hand-operated turbine speed reducer.

[0060] In an embodiment of the present application, please refer to Figures 1 to 9 The rotating frame 22 comprises two rotating shafts 221, two rotating rods 222, a first connecting rod 223 and a supporting rod 224. The two rotating shafts 221 are rotatably arranged in the rack 1 and are spaced apart. The two rotating rods 222 are respectively installed on the two rotating shafts 221. The first connecting rod 223 is connected between the two rotating rods 222. The supporting rod 224 is connected to the first connecting rod 223 and is located between the two rotating rods 222. The clamping piece 23 comprises a first mounting section 231, two arc-shaped sections 232 and two second mounting sections 233. The first mounting section 231 is installed on the rack 1. The two arc-shaped sections 232 are connected to one end of the first mounting section 231 close to the rotating frame 22 and are spaced apart. The two second mounting sections 233 are respectively connected to one end of the two arc-shaped sections 232 away from the first mounting section 231 and are configured to move towards each other under the drive of external bolts to move the two arc-shaped sections 232 towards each other.

[0061] Specifically, when the lubricating system 5 needs to tilt forward, the test personnel drives one of the rotating shafts 221 to rotate clockwise around the first direction through the first speed reducer 21. Under the drive of the rotating shaft 221, the rotating rod 222, the first connecting rod 223 and the supporting rod 224 all rotate clockwise around the first direction, and the lubricating system 5 can be driven to tilt forward through the second adjusting assembly 3. When the lubricating system 5 needs to tilt backward, the test personnel drives one of the rotating shafts 221 to rotate counterclockwise around the first direction through the first speed reducer 21. Under the drive of the rotating shaft 221, the rotating rod 222, the first connecting rod 223 and the supporting rod 224 all rotate counterclockwise around the first direction, and the lubricating system 5 can be driven to tilt backward through the second adjusting assembly 3.

[0062] More specifically, according to the test requirement, after the lubricating system 5 is inclined forward or backward to the target angle, the tester locks the two second mounting segments 233 through the external bolts. Under the action of the external bolts, the two second mounting segments 233 move towards each other, and the two second mounting segments 233 can drive the two arc-shaped segments 232 to move towards each other. Under the action of the two arc-shaped segments 232, the other shaft 221 can be locked.

[0063] In this way, the shaft 221, the rotating rod 222, the first connecting rod 223 and the supporting rod 224 are adopted, and the lubricating system 5 is driven to rotate around the first direction by the second adjusting assembly 3 under the cooperation of the first speed reducer 21, so that the posture of the lubricating system 5 is adjusted. Since the first connecting rod 223 is connected between the same ends of the two rotating rods 222, the second adjusting assembly 3 is conveniently installed, so that the second assembly is located between the two rotating rods 222, and the structure is simplified. The two second mounting segments 233 are adopted, and the two arc-shaped segments 232 can tightly hold the shaft 221 under the action of the external bolts. Under the cooperation of the first mounting segment 231, the shaft 221 is prevented from rotating around the first direction relative to the rack 1, and the lubricating system 5 is prevented from rotating around the first direction relative to the rack 1, so that the lubricating system 5 is prevented from rotating relative to the rack 1 during the test, and the test error caused by the rotation of the lubricating system 5 relative to the rack 1 is prevented, and the test is facilitated.

[0064] In an embodiment of the present application, referring to Figures 1 to 9 The second adjusting assembly 3 comprises a second speed reducer 31, a rotating plate 32, a supporting piece 33 and a plurality of limiting pieces 34. The second speed reducer 31 is installed on the rotating rack 1. The rotating plate 32 is installed on the output end of the second speed reducer 31 and can rotate around the second direction under the driving of the second speed reducer 31. The supporting piece 33 is installed between the rotating rack 22 and the rotating plate 32. The plurality of limiting pieces 34 are slidably installed on the rotating rack 22 and can be clamped on the rotating plate 32.

[0065] Specifically, when the lubricating system 5 needs to be inclined to the left, the tester drives the rotating plate 32 to rotate counterclockwise around the second direction through the second speed reducer 31, so that the lubricating system 5 is inclined to the left, and the lubricating system 5 is inclined to the left until the target angle. When the lubricating system 5 needs to be inclined to the right, the tester drives the rotating plate 32 to rotate clockwise around the second direction through the second speed reducer 31, so that the lubricating system 5 is inclined to the right, and the lubricating system 5 is inclined to the left until the target angle. When the lubricating system 5 does not need to be inclined to the left or to the right, the tester clamps the plurality of limiting pieces 34 on the rotating plate 32, so that the rotating plate 32 cannot rotate around the second direction.

[0066] With the arrangement, the second speed reducer 31 is adopted, the test personnel can drive the rotating frame 22 to rotate around the second direction, so that the lubricating system 5 can be tested to lean left or right, the test personnel can adjust the posture of the lubricating system 5, the working condition of the lubricating system 5 can be simulated, and the test is facilitated. The rotating plate 32 is adopted, the driving assembly 4 is facilitated to be installed. Moreover, the speed of the gear structure inside the lubricating system 5 can be adjusted through the driving assembly 4, and the working condition of the lubricating system 5 can also be simulated, and the test is facilitated. The supporting piece 33 is adopted, and the rotating plate 32 and the supporting plate can be hinged under the cooperation of the supporting plate. The supporting plate can support the rotating plate 32 through the supporting piece 33, which helps to improve the structural stability between the first adjusting assembly 2 and the second adjusting assembly 3, and then helps to improve the structural stability between the rack 1 and the lubricating system 5, and the lubricating system 5 is not prone to shaking, and the test is facilitated. The limiting piece 34 is adopted, and the lubricating system 5 can be kept horizontal in the second direction. When only the lubrication condition of the lubricating system 5 needs to be tested to lean forward or lean backward, the lubricating system 5 can be prevented from rotating around the second direction, the test is facilitated, and the use convenience is improved. Moreover, the limiting piece 34 is provided in a plurality of ways, compared with the case where the limiting piece 34 is provided in only one way, the stability of the lubricating system 5 in the second direction is further improved.

[0067] Optionally, the second speed reducer 31 is a hand-operated turbine speed reducer.

[0068] In an embodiment of the present application, please refer to Figures 1 to 9 The supporting piece 33 includes a first bearing seat 331, a plurality of second bearing seats 332, a plurality of third bearing seats 333, and a supporting shaft 334. The first bearing seat 331 is installed on the rotating plate 32 and is clamped to the output end of the second speed reducer 31. The plurality of second bearing seats 332 are all installed on the rotating plate 32. The plurality of third bearing seats 333 are all installed on the rotating frame 22. The supporting shaft 334 is arranged through the plurality of second bearing seats 332 and the plurality of third bearing seats 333. The limiting piece 34 includes a second connecting rod 341, a first clamping hook 342, and a second clamping hook 343. The first clamping hook 342 is connected to one end of the second connecting rod 341 close to the rotating frame 22 and is clamped to the rotating frame 22 and can slide in the first direction. The second clamping hook 343 is connected to one end of the second connecting rod 341 close to the rotating plate 32 and is configured to be clamped to the rotating plate 32 after moving in the first direction through the first clamping hook 342 and is further configured to be fixed to the rotating plate 32 by an external latch after being clamped to the rotating plate 32.

[0069] In this way, by adopting the first bearing seat 331, the rotating plate 32 can be clamped to the output end of the second speed reducer 31, so that the second speed reducer 31 drives the rotating plate 32 to rotate in the second direction, so that the lubricating system 5 can realize left or right inclination. By adopting the second bearing seat 332, the third bearing seat 333 and the supporting shaft 334, the support plate and the rotating plate 32 can be hinged. When the rotating plate 32 rotates in the second direction, the support plate supports the rotating plate 32 through the second bearing seat 332, the third bearing seat 333 and the supporting shaft 334, which helps to improve the rotation stability of the rotating plate 32 in the second direction, thereby helping to improve the rotation stability of the lubricating system 5 in the second direction, and also helping to improve the structural stability between the first adjusting assembly 2 and the second adjusting assembly 3, facilitating the adjustment of the attitude of the lubricating system 5. Moreover, the number of the second bearing seat 332 and the number of the third bearing seat 333 are both set to be multiple, which helps to further improve the rotation stability of the lubricating system 5 in the second direction, and also helps to further improve the structural stability between the first adjusting assembly 2 and the second adjusting assembly 3.

[0070] In an embodiment of the present application, please refer to Figures 1 to 9 The driving assembly 4 comprises a driver 41, a driving piece 42, a transmission piece 43 and a driven piece 44. The driver 41 is detachably installed on the second adjusting assembly 3. The driving piece 42 is detachably installed on the rotating plate 32. The transmission piece 43 is installed between the output end of the driver 41 and the driving piece 42, and can drive the lubricating system 5 to rotate by transmitting power from the driver 41 to the driving piece 42. The driven piece 44 is detachably installed on the rotating plate 32, and can rotate under the drive of the lubricating system 5.

[0071] Specifically, when the device is used, the driver 41 can transmit power to the driving piece 42 through the transmission piece 43. Under the action of the driving piece 42, power can be transmitted to the gear structure of the lubricating system 5. Under the action of the lubricating system 5, power can be transmitted to the driven piece 44.

[0072] In this way, by adopting the driver 41, power can be provided for the operation of the lubricating system 5. Moreover, by controlling the rotating speed of the output end of the driver 41, the rotating speed of the gear structure in the lubricating system 5 can be controlled, which can also be used to simulate the working condition of the lubricating system 5, helping to further expand the application range and facilitate testing. By adopting the transmission piece 43, the power of the driver 41 can be transmitted to the lubricating system 5. Moreover, it is convenient to install the driving piece 42, so that the structure of the device is more compact. Under the cooperation of the driving piece 42, the power of the driver 41 can be transmitted to the lubricating system 5. By adopting the driven piece 44, the lubricating system 5 can be stably operated, facilitating the normal testing.

[0073] Alternatively, the driver 41 may be configured as a motor.

[0074] In one embodiment of this application, see [reference] Figures 1 to 9 The driving component 42 includes a torque sensor 421, two fourth bearing seats 422, a drive shaft 423, and a coupling 424.

The two fourth bearing seats 422 are detachably mounted on the second adjusting assembly 3 and are spaced apart. The drive shaft 423 is rotatably passed between the two fourth bearing seats 422. The coupling 424 is installed between the drive shaft 423 and the coupling 424. The transmission component 43 includes a driving gear 431 and a driven gear 432. The driving gear 431 is mounted on the output end of the driver 41 and can rotate under the drive of the driver 41.

The driven member 44 includes two fifth bearing seats 441 and a driven shaft 442. The two fifth bearing seats 441 are detachably mounted on the second adjusting assembly 3 and are spaced apart. The driven shaft 442 passes between the two fifth bearing seats 441 and can rotate under the drive of the lubrication system 5.

[0075] Specifically, when using this device, the driver 41 drives the drive gear 431 to rotate, and the drive gear 431 drives the driven gear 432 to rotate. Under the action of the driven gear 432, power can be transmitted to the input shaft of the torque sensor 421 and output from the output shaft of the torque sensor 421. Under the action of the torque sensor 421, power can be transmitted to the coupling 424, and the coupling 424 can be driven to rotate. Under the action of the coupling 424, power can be transmitted to the drive shaft 423, and the drive shaft 423 can be driven to rotate. Under the action of the drive shaft 423, power can be transmitted to the lubrication system 5, thereby enabling the lubrication system 5 to operate. Under the action of the gear structure inside the lubrication system 5, power can be transmitted to the driven shaft 442, and the driven shaft 442 can be driven to rotate.

[0076] In this way, the driving force of the driver 41 can be transmitted to the lubricating system 5 to make the lubricating system 5 operate normally by using the driving gear 431, the driven gear 432, the torque sensor 421, the driving shaft 423 and the coupling 424. The torque output by the driven gear 432 can be detected by using the torque sensor 421. Since the driving shaft 423 and the gear structure of the lubricating system 5 are coaxially arranged, the torque acting on the lubricating system 5 by the driving shaft 423 can be measured, which is convenient for subsequent test measurement and analysis. The fourth bearing seat 422 is used to facilitate the installation of the driving shaft 423, which helps to improve the rotation stability of the driving shaft 423, so that the driving force of the driver 41 can be stably transmitted to the lubricating system 5. The driven shaft 442 can be assembled with the gear structure in the lubricating system 5, which helps to improve the rotation stability of the gear structure in the lubricating system 5 when the driving shaft 423 drives the gear structure in the lubricating system 5 to operate. The fifth bearing seat 441 is used to facilitate the installation of the driven shaft 442, which helps to improve the rotation stability of the driven shaft 442, so that the lubricating system 5 can operate more stably.

[0078] In this way, the driver 41 can be detachably connected with the rotating plate 32 by using the plurality of first waist-shaped holes 35 in cooperation with external bolts. According to actual application requirements, the position of the driver 41 on the first waist-shaped holes 35 can be adjusted.

In summary, by adjusting the relative positions among the driver 41, the fourth bearing seat 422 and the fifth bearing seat 441, the rotating plate 32 can be used to install drivers 41 of different specifications. By adjusting the relative positions between the fourth bearing seat 422 and the fifth bearing seat 441, the rotating plate 32 can be used to install lubricating systems 5 of different specifications, which helps to further improve the application range of the device.
