Referring to fig. 1 and fig. 2, a floating oil seal testing apparatus 10 according to a preferred embodiment of the present invention includes a base 100, a sliding mechanism 200, a rotating mechanism 300, and a mounting base 400.
The base 100 serves as a support and may be a metal plate-like structure. The sliding mechanism 200, the rotating mechanism 300, and the mounting base 400 are all mounted on the base 100.
The sliding mechanism 200 includes a first sliding member 210 and a second sliding member 220. The second sliding member 220 is mounted to the driving end of the first sliding member 210, and the rotating mechanism 300 is mounted to the driving end of the second sliding member 220. The first sliding component 210 can drive the second sliding component 220 to slide along a first direction, and the second sliding component 220 can drive the rotating mechanism 300 to slide along a second direction perpendicular to the first direction. As shown in fig. 1, the first direction refers to a horizontal direction, and the second direction refers to a direction perpendicular to the plane of the drawing sheet.
In this embodiment, the first sliding assembly 210 includes a first guide rail 211, a first sliding base 212 and a motor screw pair 213, and the first sliding base 212 is slidably disposed on the first guide rail 211 and can slide along the first guide rail 211 under the driving of the motor screw pair 213. The first guide rail 211 extends along a first direction, and a servo motor of the motor screw pair 213 can drive the screw to rotate through a speed reducer, so as to drive the first sliding base 212 to slide.
Further, the second sliding assembly 220 includes a second guiding rail 221 and a second sliding seat 222, the second guiding rail 221 is fixed to the first sliding seat 212, and the second sliding seat 222 is slidably disposed on the second guiding rail 221. The second guide rail 221 extends along the second direction, and the second slider 222 may be a plate-shaped structure for supporting.
It should be noted that, in other embodiments, the first sliding member 210 and the second sliding member 220 may have other structures.
The rotation mechanism 300 is capable of rotating about a rotation axis (not shown) extending in a third direction perpendicular to the first direction and the second direction. As shown in fig. 1, the third direction refers to a vertical direction, i.e., the rotation axis of the rotation mechanism 300 extends in the vertical direction. Also, the rotation mechanism 300 includes a main shaft 310, the main shaft 310 extending in a first direction.
As shown in fig. 3 to 6, the floating oil seal to be tested comprises a dynamic floating seal ring 21 and a static floating seal ring 22. In the test, the floating seal ring 21 is attached to the main shaft 310, so that the floating seal ring 21 can be rotated by the main shaft 310. Specifically, the rotating mechanism 300 generally includes a motor and a speed reducer, and the main shaft 310 is disposed at an output end of the speed reducer. Therefore, under the same output power, the main shaft 310 can obtain larger torque, which is beneficial to driving the dynamic floating seal ring 21 with larger size to rotate.
Referring to fig. 7 and 8, in the present embodiment, the floating oil seal testing apparatus 10 further includes a first housing assembly 700 configured with the main shaft 310, the first housing assembly 700 includes a plurality of movable housing cavities 710 that are coaxially and detachably nested, and each movable housing cavity 710 can mount the floating seal ring 21.
Specifically, the diameters of the plurality of movable seat cavities 710 are gradually changed, and each movable seat cavity 710 can be correspondingly provided with a movable floating seal ring 21 of a certain floating oil seal of a specific type. In the test, after the movable seat cavity 710 matching with the size of the movable floating seal ring 21 is selected, the other movable seat cavities 710 outside the matched movable seat cavity 710, i.e., the movable seat cavities 710 with larger diameters than the matched movable seat cavity 710, can be sequentially detached to expose the matched movable seat cavity 710. Therefore, the floating oil seal testing device 10 can be applied to testing of different types of floating oil seals.
As shown in fig. 7, when a small-sized floating oil seal is tested, the movable seat chamber 710 with the movable floating seal ring 21 can be directly assembled on the main shaft 310.
When a large-size floating oil seal is tested, as shown in fig. 8, the movable seat cavity 710 provided with the movable floating seal ring 21 is large in size, so that the movable seat cavity is not convenient to be directly assembled on the main shaft 310. At this time, the movable seat cavities 710 with smaller diameters can be assembled on the main shaft 310 in sequence. Then, the movable seat cavity 710 with the movable floating seal ring 21 is installed on the movable seat cavity 710 with the smaller diameter. Therefore, the movable seat cavity 710 provided with the movable floating seal ring 21 is not directly connected with the main shaft 310, and the large-specification floating oil seal can be tested more conveniently through the transition effect of other movable seat cavities 710.
The mounting seat 400 is mounted on the base 100 and spaced apart from the rotating mechanism 300 in the first direction, and the mounting seat 400 is used for mounting the static and floating seal ring 22. The first sliding assembly 210 can drive the rotating mechanism 300 to slide along a first direction, so as to enable the floating seal ring 21 and the static floating seal ring 22 to approach or separate from each other.
In this embodiment, the floating oil seal testing device 10 further includes a second housing assembly 800 configured with the mounting base 400, the second housing assembly 800 includes a plurality of coaxial and detachably nested static housing cavities 810, and each static housing cavity 810 is capable of mounting the static floating seal ring 22.
The second housing assembly 800 and its static housing 810 are structurally and functionally identical to the first housing assembly 700 and the dynamic housing 710, respectively. The second housing assembly 800 is configured to enable the mounting block 400 to be mounted for static and floating seal rings 22 of different sizes. Similarly, the diameters of the plurality of static seat cavities 810 are gradually changed, and each static seat cavity 810 can correspond to the static floating seal ring 22 for installing a certain type of floating oil seal. In testing, after selecting the static seat cavity 810 matched with the size of the static floating seal ring 22, the other static seat cavities 810 outside the matched static seat cavity 810, i.e. the static seat cavities 810 with larger diameters than the matched static seat cavity 810, can be sequentially detached to expose the matched static seat cavity 810.
As shown in fig. 7, when testing for a smaller sized floating oil seal, the stationary housing 810 with the stationary floating seal ring 22 mounted thereon may be directly mounted on the mounting 400.
As shown in fig. 8, when testing a floating oil seal with a larger size, the static seat cavity 810 provided with the static floating seal ring 22 is not directly connected with the mounting seat 400, but is assembled with the mounting seat 300 after passing through the other static seat cavities 810.
In actual use, the assembly relationship of the floating seal ring 21 and the static floating seal ring 22 has the following three conditions:
as shown in fig. 3, under ideal conditions, the dynamic floating seal ring 21 and the static floating seal ring 22 are coaxially installed;
as shown in fig. 4, the dynamic floating seal ring 21 and the static floating seal ring 22 have small dislocation in the radial direction, and the two are in a non-coaxial state but have parallel central lines;
as shown in fig. 5, the dynamic floating seal ring 21 and the static floating seal ring 22 are not dislocated in the radial direction, and a smaller included angle exists between the end surface of the dynamic floating seal ring 21 and the end surface of the static floating seal ring 22;
as shown in fig. 6, the dynamic floating seal ring 21 and the static floating seal ring 22 are in a non-coaxial installation state due to large error or poor installation. At this time, the dynamic floating seal ring 21 and the static floating seal ring 22 are dislocated in the radial direction, and a small included angle exists between the end face of the dynamic floating seal ring 21 and the end face of the static floating seal ring 22.
When testing the floating oil seal, the dynamic floating seal ring 21 and the static floating seal ring 22 can be installed on the main shaft 310 and the installation seat 400 of the rotating mechanism 300 respectively; then, the first sliding assembly 210 moves to drive the rotating mechanism 300 to approach the mounting seat 400 until the dynamic floating seal ring 21 abuts against the end face of the static floating seal ring 22. The rotating mechanism 300 drives the main shaft 310 to rotate, so that a rotation test can be realized on the floating oil seal.
Further, by operating the second slide unit 220, the relative positions of the dynamic floating seal ring 21 and the static floating seal ring 22 can be adjusted in the radial direction, so that the coaxiality of the dynamic floating seal ring 21 and the static floating seal ring 22 is adjusted, and the assembly relationship between the two is sequentially in the state shown in fig. 3 and 4. Further, by rotating the rotation mechanism 300 about the rotation axis, the angle between the end surface of the dynamic floating seal ring 21 and the end surface of the static floating seal ring 22 can be adjusted so that the fitting relationship therebetween is in the state shown in fig. 5 and 6.
Therefore, the floating oil seal testing device 100 can perform rotation tests on floating oil seals in coaxial and non-coaxial states, so that the floating oil seals can be tested under the condition of being closer to the actual working condition, and the accuracy of the test results is improved.
In this embodiment, the floating oil seal testing device 10 further includes a temperature sensor (not shown), and the probe 910 of the temperature sensor can extend into any of the static seat cavities 810. So, when carrying out rotation test, temperature sensor can realize real-time detection to floating oil seal's ring body temperature.
In addition, in this embodiment, the floating oil seal testing device 10 further includes an oil injection device, and the self-closing quick-change connector 920 of the oil injection device can extend into any one of the static seat cavities 810 and can inject oil into the static seat cavity 810, so as to determine whether the floating oil seal will cause leakage during rotation.
Referring to fig. 1 again, in the present embodiment, the sliding mechanism 200 further includes a third sliding element 230, the third sliding element 230 is mounted at the driving end of the second sliding element 220 and can slide along the second direction under the driving of the second sliding element 220, the rotating mechanism 300 is mounted at the moving end of the third sliding element 230, and the third sliding element 230 allows the rotating mechanism 300 to slide along the first direction.
In this way, when the first sliding unit 210 drives the rotating mechanism 300 to slide in the first direction and the floating seal ring 21 mounted on the main shaft 310 is abutted against the floating seal ring 22 mounted on the mounting base 400, the rotating mechanism 300 can perform buffering in the first direction.
Further, in the present embodiment, the third sliding assembly 230 includes a third guiding rail (not shown) and a third sliding base (not shown), the third guiding rail is fixed to the second sliding base 222, the third sliding base is slidably disposed on the third guiding rail, and the rotating mechanism 300 is rotatably mounted on the third sliding base.

When the first slider 212 advances and brings the end face of the floating seal ring 21 into contact with the end face of the static floating seal ring 22, a contact pressure is generated. The pressure is transmitted to the measuring end of the pressure sensor 500 through the main shaft 310 and the third slide seat, so that the pressure between the end surfaces of the dynamic floating seal ring 21 and the static floating seal ring 22 is accurately detected.
In addition, in order to reduce the influence of the rail resistance on the pressure of the end face of the floating oil seal, ball rails having a small friction coefficient are used for the first rail 211, the second rail 221, and the third rail in this embodiment. In order to prevent dust, as shown in fig. 9, the sliding mechanism 200 may further include a shield 240, and the shield 240 may be disposed to cover the first sliding unit 210, the second sliding unit 220, and the third sliding unit 230.

Thus, the sliding mechanism 200 and the rotating mechanism 300 on both sides can be operated simultaneously. Therefore, the floating oil seal testing device 100 can test two floating oil seals simultaneously, and is beneficial to improving the efficiency.
In the floating oil seal testing apparatus 10, the floating seal dynamic floating seal ring 21 and the static floating seal ring 22 can be respectively mounted on the main shaft 310 and the mounting base 400 of the rotating mechanism 300.
