In a specific embodiment, the wheel body includes a wheel body 7 and a shaft sleeve 8, the shaft sleeve 8 is disposed inside the wheel body 7, and an axis of the shaft sleeve 8 coincides with an axis of the wheel body 7. The shaft sleeve 8 is in interference fit with the wheel body 7. Specifically, the sleeve 8 may be pressed into the interior of the wheel body 7 by a press.
The wheel axle 1 is located inside the shaft sleeve 8, the shaft sleeve 8 is in clearance fit with the wheel axle 1, and the clearance between the shaft sleeve 8 and the wheel axle 1 corresponds to the clearance between the wheel body and the wheel axle 1. The shaft sleeve 8 is in contact with the wheel shaft 1 instead of the wheel body 7, so that abrasion to the wheel body 7 can be reduced.
The first through hole 2 may simultaneously penetrate the wheel body 7 and the sleeve 8.
When the annular groove 5 is formed in the wheel body, the annular groove 5 can be formed in the wheel body 7, the shaft sleeves 8 are arranged in a segmented mode, the two sections of shaft sleeves 8 are respectively located on two sides of the annular groove 5, and at the moment, only the first through hole 2 needs to penetrate through the wheel body 7.

The floating seal 9 consists of two identical support rings and two sealing rings. The two support rings are in fit contact, and the two sealing rings are respectively positioned on one sides far away from the two support rings. The sealing ring is in extrusion contact with the end surface of the end cover 3 and the end surface of the wheel body under the supporting action of the supporting ring. The end surfaces of the two support rings, which are close to each other, are processed and can be in sealing contact under the extrusion action of the seal ring, so that the sealing between the end cover 3 and the wheel body is realized.
When the crawler wheel is assembled, the sealing ring needs to be ensured to have a certain extrusion deformation amount, and in the working process of the crawler wheel, if the two support rings are abraded, the sealing between the end cover 3 and the wheel body can still be maintained under the action of the sealing ring. Therefore, the floating sealing element 9 is stable in sealing performance and beneficial to prolonging the service life of the crawler wheel.
The support ring is made of wear-resistant metal, so that the wear efficiency of the support ring can be reduced, and the service life of the floating sealing piece 9 can be prolonged.

As the working time of the crawler wheel increases, the metal powder in the crawler wheel gradually increases, and the temperature of the lubricating oil gradually increases during the abrasion process of the wheel body and the wheel axle 1. When the temperature of the lubricating oil rises to a certain degree, the abrasion between the wheel body and the wheel shaft 1 is serious, and the metal powder between the wheel body and the wheel shaft 1 is excessive and needs to be cleaned.
In this embodiment, the track wheel further includes a temperature detection element 6, and the temperature detection element 6 is fixedly disposed in the annular groove 5 and is used for detecting the temperature of the lubricating oil in the annular groove 5.
The temperature detection element 6 detects the temperature of the lubricant in the annular groove 5, generates lubricant temperature data, and outputs the lubricant temperature data.
For example, the temperature detection element 6 is electrically connected to a control system, and the control system can receive the above-described lubricating oil temperature data.
After receiving the lubricating oil temperature data, the control system can directly output the lubricating oil temperature data to a display device for a user to obtain.
Also can be through control system contrast lubricating oil temperature data and preset threshold value, when lubricating oil temperature data is greater than preset threshold value, output warning information to remind the wearing and tearing state of user's athey wheel, thereby in time clear up the metal powder in the athey wheel.
The temperature detection element 6 is arranged, so that a user can know the internal state of the crawler wheel in time without disassembling.
Specifically, the temperature detection element 6 may be a temperature sensor.
In an optional embodiment, a temperature sensor with a buzzer can be selected, and when the detected lubricating oil temperature data is greater than a preset threshold value, an audible alarm signal can be sent.
In this embodiment, the temperature detecting element 6 has a magnetic portion, and the magnetic portion is fixedly connected to the temperature detecting element 6.
