Abstract

The invention discloses a mine car wheel. The middle of a half shaft is sleeved with a bearing, the outer side of the bearing is fixed in an inner cavity of the wheel, an annular groove is formed in the inner surface of the wheel, an inner-side sealing cover is fixed in the annular groove through bolts, and the thickness of the inner-side sealing cover is smaller than or equal to the groove depth of the annular groove; the half shaft penetrates through the middle of the inner-side sealing cover, and is in contact with the inner-side sealing cover through an O-shaped ring in a sealed mode; the diameter of an outer-side sealing cover is matched with the inner cavity of the wheel, the outer-side sealing cover is arranged in the inner cavity of the wheel, and the outer-side sealing cover and the inner-side sealing cover are arranged on the two sides of the bearing respectively; the half shaft penetrates through the outer-side sealing cover, a round nut is fixed on the half shaft in a threaded mode, one side of the round nut and the outer-side sealing cover are pressed through a stop washer, and the other side of the round nut is located in the inner cavity of the wheel. According to the mine car wheel, the inner-side sealing cover and the outer-side sealing cover are designed in the end face of the wheel, it is avoided that a mine car is cut through a steel rail when the mine car is derailed accordingly, the wheel newly enters the rail, and then can normally run, and the influence on mine working is reduced.

Description

Technical field: [0001] The invention relates to the technical field of rail mine vehicles, in particular to a mine vehicle wheel. Background technique: [0002] The current rail mine car is divided into full axle according to the wheel axle (such as figure 1 shown) and semi-axis (as figure 2 Shown), its basic structure is: axle 11,11 ' is connected with wheel 13 by bearing 12, and wheel 13 both sides are provided with seal cover 14,14 ', and seal cover 14,14 ' all protrudes outward. Due to the harsh working environment of the rail mine car, derailment often occurs, and since the sealing covers 14, 14` are non-load-bearing parts, at this time, under high loads, the protruding sealing covers 14, 14` will be cut off by the track, thereby making the track The mine cart was severely damaged, affecting normal work. Invention content: [0003] In view of this, it is necessary to design a mine vehicle wheel structure so that the wheels will not be severely damaged when the ra...
