Abstract
The utility model discloses a thrust wheel hub of a bulldozer. The thrust wheel hub of the bulldozer comprises a hub body, wherein the hub body comprises a wheel body mounting section, and first and second end cover mounting sections, wherein the wheel body mounting section is arranged in the middle part; the first and second end cover mounting sections are arranged at two sides of the wheel body mounting section; an oil storage tank is formed at the periphery of the wheel body mounting section; a main oil way communicated with the oil storage tank is formed in the hub body; a first branch circuit of which one end is communicated with the main oil way and an opening of the other end is arranged at the periphery of the first end cover mounting section is formed in the hub body; a second branch circuit of which one end is communicated with the oil storage tank and the opening at the other end is arranged at the periphery of the second end cover mounting section is formed in the hub body; the oil storage tank can store lubricating oil; and the lubricating oil stored in the oil storage tank fully contacts with a bearing during working. Compared with the prior art, the lubricating effect of the thrust wheel is greatly improved; abnormal abrasion between the components is reduced; and the service life of the thrust wheel is effectively prolonged.
Description
Technical field
The utility model relates to bulldozer caterpillar wheel wheel shaft.
Background technology
so caterpillar wheel weight of supporting excavation machine and bulldozer, allow crawler belt advance along wheel, its keystone configuration comprises wheel shaft, wheel body, end cap, axle sleeve and poted assemblies, wheel shaft is comprised of the wheel body construction section that is positioned at the middle part and the end cap construction section that is positioned at wheel body construction section both sides, wheel body is sheathed on the wheel body construction section, axle sleeve is sheathed between wheel body and wheel body construction section, end cap is sheathed on the end cap construction section, usually being formed with an end in wheel shaft is communicated with oil supply source, the other end is opened on the oil circuit with wheel body construction section outer peripheral face, by oil circuit, the lubricating oil in oil supply source is led on axle sleeve during work, axle sleeve is lubricated, owing between existing wheel body construction section and wheel body, oil-bearing structure not being set, can't store lubricating oil, and axle sleeve, combine closely between wheel body construction section and wheel body, the oil mass that can enter axle sleeve is less, therefore, axle sleeve, lubricant effect between wheel body construction section and wheel body is poor, easily cause the heel and toe wear between parts, shorten the service life of caterpillar wheel.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and the bulldozer caterpillar wheel wheel shaft of a kind of simple in structure, high lubricating effect, long service life is provided.
The purpose of this utility model realizes by following technical solution:
Bulldozer caterpillar wheel wheel shaft, comprise the wheel shaft body, described wheel shaft body comprises the wheel body construction section that is positioned at the middle part and first, second end cap construction section that is positioned at wheel body construction section both sides, it is characterized in that: described wheel body construction section outer peripheral face is formed with oil resevoir, be formed with the working connection that is communicated with described oil resevoir in described wheel shaft body, be formed with an end in described wheel shaft body and be communicated with described working connection, the other end is opened on the first branch road of the first end cap construction section outer peripheral face; Be formed with an end in described wheel shaft body and be communicated with described oil resevoir, the other end is opened on the second branch road of the second end cap construction section outer peripheral face.
Further, 45 ° of extensions of tilting of described second curb relative level face.
Further, described wheel body construction section outer peripheral face is formed with two described oil resevoirs of circle distribution, and described working connection is communicated with described oil resevoir by the 3rd branch road.
Further, the degree of depth of described oil resevoir is radially extended along described wheel body construction section, and the length of described oil resevoir extends axially along described wheel body construction section.
Further, the degree of depth of described oil resevoir is less than or equal to 1/4th of the diameter of described wheel body construction section.
The utlity model has following beneficial effect:
Be formed with oil resevoir at wheel body construction section outer peripheral face, and be formed with the working connection that is communicated with oil resevoir in the wheel shaft body, working connection is connected with outside oil supply source, can inject lubricating oil in oil resevoir, the lubricating oil that is stored in oil resevoir can fully contact with bearing when work, and compared with prior art, the utility model has improved the lubricant effect of caterpillar wheel greatly, reduce the heel and toe wear between parts, effectively improved the service life of caterpillar wheel; By the first branch road, the lubricating oil of working connection is directed to the first end cap construction section outer peripheral face, lubricating oil in oil resevoir can be directed to the second end cap construction section outer peripheral face by the second branch road, thereby the end cap to both sides is lubricated, reduce the friction between end cap and wheel shaft, improve the service life of end cap, the degree of depth of oil resevoir is set to can guarantee axle bearing intensity like this less than or equal to 1/4th of the diameter of wheel body construction section, prevents from affecting axle bearing intensity because of offering of oil resevoir.
Description of drawings
