Description

Technical Field

[0001] This application relates to the technical field of bushings, and in particular to a track bushing wear testing device. Background Technology

[0002] Bushing wear is a common failure in construction machinery, especially in tracked chassis running gear. To extend the service life of track bushings, various forms of sealing and pin bushing inner hole structures have emerged, exploring more reliable pin bushing structures, bushing fit clearances, and lubrication and sealing methods. Currently, in the track design field, there are many suppliers of sealing components, and the dynamic sealing structures are largely similar. However, the quality of sealing materials varies greatly, and the pin bushing inner hole structures and lubrication effects also differ significantly. This results in substantial differences in the wear resistance of pin bushings between different manufacturers, with lifespan differences reaching more than three times. Furthermore, companies lack effective means to verify the causes of bushing failures. Utility Model Content

[0003] To address the shortcomings of existing technologies, one of the objectives of this application is to provide a track bushing wear testing device that has the advantage of being able to verify bushing failure.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A track bushing wear testing device includes a base plate, on which a loading device is provided. The loading device includes a contact element, a buffer element, and a power element. The contact element is used to contact the bushing. The buffer element is located between the contact element and the power element to transmit the power generated by the power element, causing the contact element to move. The buffer element is also used to store power.

[0006] By adopting the above technical solution, during use, the buffer transmits power to the contacting part, so that the contacting part comes into contact with the bushing and applies force to the bushing. At the same time, the buffer stores power, so that during use, it can compensate for the wear of the pin sleeve, thereby achieving the purpose of verifying bushing failure.

[0007] In a preferred embodiment, the present application may be further configured such that the contact element includes a movable seat, on which a rotating element is connected, and the rotating element is in contact with the bushing.

[0008] By adopting the above technical solution, the presence of the rotating component ensures that the rotating component also rotates when the pin sleeve rotates, thereby reducing the probability of high temperature generated by pin sleeve friction.

[0009] In a preferred embodiment, the present application may be further configured such that: there are two sets of rotating members, the two sets of rotating members form a receiving groove for accommodating the bushing, and both sets of rotating members are in contact with the bushing.

[0010] By adopting the above technical solution, the contact effect with the bushing is improved.

[0011] In a preferred embodiment, this application may further be configured to include a locking element located between the buffer and the power element for power transmission, and the locking element also for maintaining the power.

[0012] By adopting the above technical solution, the presence of the locking component ensures that the load still exists even after the power is removed from the power component, thus guaranteeing the stability of the load.

[0013] In a preferred embodiment, the locking element may be further configured as follows: the locking element includes a locking seat, a transmission rod, and a stop element; the stop element and the transmission rod are connected and the connection position is adjustable; the locking seat is fixedly mounted on the base plate; the locking seat has a through hole for the transmission rod to extend out; the stop element is located on the side of the locking seat away from the power element; the stop element is mounted on the transmission rod and is used to contact the locking seat.

[0014] By adopting the above technical solution, during use, when the transmission rod moves to a suitable position under the action of the power component, the stop component moves, so that the stop component and the locking seat come into contact.

[0015] In a preferred embodiment, this application may be further configured such that the transmission rod is threaded and the stop is a nut adapted to the thread.

[0016] By adopting the above technical solution, the load can be kept constant or adjusted by rotating the nut during use.

[0017] In a preferred embodiment, the buffer element may be further configured as a spring.

[0018] By adopting the above technical solution, the presence of the spring enables the storage and transmission of power.

[0019] In a preferred embodiment, the application may be further configured such that the loading device includes a pressure sensor for detecting the force applied by the contact to the pin sleeve. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2 This application discloses a track bushing wear testing device, comprising a base plate 1, on which a loading device is mounted. The loading device includes a pressure sensor 3, a contact element 2, a buffer element 4, a locking element 5, and a power element 6. In this application, the power element 6 is a pneumatic cylinder or a hydraulic cylinder.

[0025] The locking component 5 includes a locking seat 53, a transmission rod 51, and a stop 52. The stop 52 is connected to the transmission rod 51, and the connection position is adjustable. The locking seat 53 is fixedly mounted on the base plate 1. The locking seat 53 has a through hole for the transmission rod 51 to extend out. The transmission rod 51 passes through the through hole and is connected to the power component 6. The stop 52 is located on the side of the locking seat 53 away from the power component 6. The stop 52 is mounted on the transmission rod 51 and is used to contact the locking seat 53. The transmission rod 51 has threads, and the stop 52 is a nut adapted to the threads.

[0026] The buffer 4 is a spring. In this embodiment, a nitrogen spring is used. One end of the buffer 4 is connected to the transmission rod 51, and the other end is connected to the pressure sensor 3.

[0027] Pressure sensor 3 is positioned between buffer 4 and contact 2.

[0028] The contact element 2 includes a movable seat 21, which is slidably connected to a base. The movable seat 21 is provided with a rotating element 22, and there are two sets of rotating elements 22. The two sets of rotating elements 22 form a receiving groove 23 for accommodating a bushing. In this embodiment, the rotating element 22 is a bearing.

[0029] The implementation principle of this embodiment is as follows: During use, the track is in a fixed state (such as fixed on the base plate 1, or pressed and fixed by other equipment). The power component 6 drives the transmission rod 51 to move, and the transmission rod 51 drives the nitrogen spring. The nitrogen spring transmits force, causing the moving seat 21 to move. The two rotating components 22 contact the pin sleeve of the track. The rotating components 22 apply a load to the pin sleeve. The load is detected by the pressure sensor 3. When the usage requirements are met, the nut is rotated so that the nut contacts the locking seat 53. Then the power output of the power component 6 is canceled. Under the action of the buffer component 4, the rotating component 22 can still maintain the load on the pin shaft. When there is wear, the buffer component 4 can compensate. The load can also be adjusted by rotating the nut.

[0030] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
