Abstract
The utility model discloses a mining tramcar wheel set comprising an axle (1), end caps (2), outer retaining rings (3), inner retaining rings (4), hexagon nuts (5), bearings (6), oil charging holes (7) and rollers (8). The bearings (6) are arranged at two ends of the axle (1), and fixed through the hexagon nuts (5). The inner retaining rings (4) are arranged on the inner side of the axle (1), the outer retaining rings (3) are arranged on the outer side of the axle (2), the rollers (8) and the end caps (2) are connected in a matched manner, the oil charging holes (7) are arranged on the rollers (8), outlets of the oil charging holes (7) correspond to the bearings (6), the end caps (2) directly contact with the axle (1) in matched manner and fixed on the rollers (8) through bolts, and oil is charged into the oil charging holes (7) and the bearings (6). Engine oil is used for substituting for lubricating grease to lubricate the bearings, the bearings can be lubricated effectively, noise is lowered, and service life of the wheel set is further guaranteed.
Description
Technical field
The utility model relates to a kind of mine car, specifically a kind of mining tramcar wheel pair.
Background technology
Mine car be in coal transport equipment quantity at most, a kind of equipment of maintenance and renovation quantity maximum.And wheel is to being the essential elements on mine car, be traveling gear, be again load carrier.In mine car damages, wheel is again the most serious to damaging.So its in-use performance receives much concern.At present, what colliery was generally used is the tramcar wheel pair of grease lubrication, although grease can play good lubricant effect in early stage, but after grease is rotten, viscosity can change, oil film is broken to be worn, and the separation function of grease and attachment characteristic just can disappear, and the consequence producing is like this concentrated in following 2 points:
(1) the acid ingredient directed oxidation metal surface that insulated paint is produced, causes bearing rust.
(2) cause steel ball and inside and outside raceway directly to touch, during rotation, wear and tear, thereby cause that noise increases.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of mining tramcar wheel pair, can effectively lubricating bearing, reduce noise, further guarantee the service life that wheel is right.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mining tramcar wheel pair, comprises wheel shaft, end cap, outer back-up ring, inner shield ring, hexagonal nut, bearing, oil hole and roller; Wheel shaft two ends arrange bearing, by hexagonal nut, fix; Wheel shaft inner side arranges inner shield ring, the outer back-up ring of arranged outside, and roller and end cap are connected, and oil hole is set on roller, and oil hole exports corresponding bearing; End cap directly contacts cooperation with wheel shaft, between oil hole and bearing, is filled with machine oil.
Bearing is two.
Compared with prior art: the utility model is filled with machine oil between oil hole and bearing, use machine oil to replace grease to be lubricated bearing; Machine oil has good resistance to elevated temperatures, viscosity index figure is high, viscosity temperature characteristic good, resistance to low temperature is good, lower volatility, flash-point and burning-point advantages of higher; Can improve the right thermal diffusivity of wheel, reduce noise emission; Add wheel centering more efficient and convenient, machine oil can regularly replace; Further guaranteed to take turns right service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, wheel shaft, 2, end cap, 3, outer back-up ring, 4, inner shield ring, 5, hexagonal nut, 6, bearing, 7, oil hole, 8, roller.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of mining tramcar wheel pair, comprises wheel shaft 1, end cap 2, outer back-up ring 3, inner shield ring 4, hexagonal nut 5, bearing 6, oil hole 7 and roller 8; Wheel shaft 1 two ends arrange bearing 6, fixing by hexagonal nut 5; Wheel shaft 1 inner side arranges inner shield ring 4, the outer back-up ring 3 of arranged outside, and roller 8 is connected with end cap 2, and oil hole 7 is set on roller 8, the corresponding bearing 6 of oil hole 7 outlet; End cap 2 directly contacts cooperation with wheel shaft 1, is bolted on roller 8, between oil hole 7 and bearing 6, is filled with machine oil.
Further, bearing 6 is two, is used in conjunction with.
During work, by being lubricated between oil hole 7 and bearing 6, replaced use machine oil to replace grease to be lubricated bearing in machine oil; Machine oil has good resistance to elevated temperatures, viscosity index figure is high, viscosity temperature characteristic good, resistance to low temperature is good, lower volatility, flash-point and burning-point advantages of higher; Can improve the right thermal diffusivity of wheel, reduce noise emission, can be lubricated bearing 6 simultaneously; Add wheel centering more efficient and convenient, machine oil can regularly replace because machine oil has flowing power, so machine oil is than the easy backflow of grease; Further guaranteed to take turns right service life.
Claims (2)
1. a mining tramcar wheel pair, comprises wheel shaft (1), end cap (2), outer back-up ring (3), inner shield ring (4), hexagonal nut (5), bearing (6), oil hole (7) and roller (8); Wheel shaft (1) two ends arrange bearing (6), fixing by hexagonal nut (5); Wheel shaft (1) inner side arranges inner shield ring (4), the outer back-up ring (3) of arranged outside, and roller (8) is connected with end cap (2), and oil hole (7) is set on roller (8), and oil hole (7) exports corresponding bearing (6); It is characterized in that, end cap (2) directly contacts cooperation with wheel shaft (1), is bolted on roller (8) upper, between oil hole (7) and bearing (6), is filled with machine oil.
2. a kind of mining tramcar wheel pair according to claim 1, is characterized in that, described bearing (6) is two.
