Due to the harsh working environment, dirt is easily introduced and they cannot withstand large axial and radial forces at the same time. Long-term work will cause rust and wear, reducing the service life and affecting the normal operation of the equipment. Frequent maintenance or even replacement is required, affecting the working efficiency of the equipment. Utility Model Content

[0044] A wheel shell 4 is provided on the two bearings 3. The outer ring of the bearing 3 away from the end (one end) of the fixed shaft 1 is set to abut against the wheel shell 4. One end of the wheel shell 4 and the fixed shaft 1 are sealed by a sealing ring A5. The other end of the wheel shell 4 is opened, and the other end of the wheel shell 4 is provided with an end cover 6. The end cover 6 is protruding from one end close to the bearing 3 and is provided with an abutting part 7. The abutting part 7 is a protruding annular ring, and the abutting part 7 is abutted against the outer ring of the bearing 3. The setting of the abutting part 7 is conducive to improving the overall assembly quality of the support wheel. A cavity is formed between the bearing 3, the fixed shaft 1 and the end cover 6, and lubricating oil is provided in the cavity.

[0045] Through the setting of the bearing 3, the wheel housing 4 can rotate around the fixed shaft 1, and the bearing 3 is sealed inside the wheel housing 4, realizing the overall sealing setting of the support wheel, and there is a cavity inside to store lubricating oil to achieve long-term lubrication, thereby increasing the service life of the support wheel and ensuring the normal operation of the equipment.

[0046] The provision of the two bearings 3 is beneficial to improving the supporting capacity of the support wheel, improving the supporting stability, and increasing the service life of the support wheel.

[0047] Bearing 3 adopts angular contact ball bearing, which can bear axial force and radial force at the same time to ensure support stability.

[0048] The sealing ring A5 includes a rotating shaft lip sealing ring, and the provision of the rotating shaft lip sealing ring ensures the sealing between the wheel housing 4 and the fixed shaft 1.
