Compared with the prior art, the wheel assembly of the cleaning machine position trailer has the advantages that: the roller bearing 3 is assembled as an independent part, and the roller bearing 3 can be independently replaced after being worn; a grease inlet is arranged in the center of the roller shaft 2 and can provide grease for the roller bearing 3. Preferably, the end cap 4 is bolted to the wheel 1 to facilitate the mounting and dismounting of the end cap 4 and the wheel 1. Wherein the bolts are circumferentially arranged on the end cover 4. By attaching the end cap 4 to the wheel 1, the left end of the roller bearing 3 can be attached inside the wheel 1.
Referring to fig. 2 to 4, on the basis of the foregoing technical solution, the cleaning machine work position trailer wheel subassembly of the present invention may further include three radial oil outlets 22 radially disposed at the left end of the roller shaft 2, and three bearing oil holes 31 disposed on the bearing inner ring and corresponding to the radial oil outlets 22. Therefore, the three radial oil outlet holes 22 are respectively communicated with the corresponding three bearing oil holes 31, and grease can enter the roller bearing 3 more conveniently. The further preferred technical scheme is as follows: the three radial oil outlet holes 22 are distributed at an equal interval angle of 120 degrees, and the three bearing oil holes 31 are distributed at an equal interval angle of 120 degrees. Therefore, in the actual process, most of the bearing oil holes 31 are distributed at equal angles of 120 degrees, so that the radial oil outlet holes 22 corresponding to the number and positions of the radial oil outlet holes 22 on the roller shaft 2 are also formed in the left end of the roller shaft 2, and the grease can enter the roller bearing 3 more uniformly.
