Abstract
A steering gear for a light crawler tractor comprises a hub. The left end of the hub is provided with a large gear ring, the left end of the large gear ring is concaved downwards, the inner side of the left end of the hub is provided with a first connection segment and a second connection segment, the right side of the hub is provided with a small gear ring, and a first W-shaped groove is formed between the large gear ring and the small gear ring; a concaved structure which is close to one side of the large gear ring and is used for separating two bearings installed in the hub is arranged on the lower portion, on the inner side of the hub, of the first W-shaped groove, and the portion, located at the top of the small gear ring, of the first W-shaped groove is provided with a second W-shaped groove. In this way, the steering gear for the light crawler tractor has the advantages of being reasonable in structural design, simple in structure, reliable in work, not prone to being disengaged and good in steering performance.
Description
Technical field
The present invention relates to machine parts field, especially relate to a kind of Light Crawler Tractor steering gear.
Background technology
South China precipitation region is generally more, causes nonirrigated farmland few, many paddy fields.At the field machine of paddy-field-working, because paddy field earth wets soft, General Purpose Rubber tire is easily absorbed in skidding, is unfavorable for operation, and thus, the normal crawler type that adopts drives.Existing agricultural track type tractor, its traveling gear generally includes drive wheel, caterpillar wheel, track adjusting wheel and crawler belt etc., and wherein, drive wheel, caterpillar wheel and track adjusting wheel are installed in inside described crawler belt.During walking, caterpillar wheel plays the effect of propping up tare, and drive wheel crawler belt rotates around caterpillar wheel and track adjusting wheel, and track adjusting wheel then mainly plays the effect of tensioned tracks.
Deflector is requisite part in vehicular spare parts, deflector all utilizes steering gear and steering nut engaged transmission to realize direction transmission, turn in housing because steering gear and steering nut are arranged on, their engagement situation cannot be observed, likely the engaging gear of steering gear and steering nut can be departed from because of automobilist's ovdersteering, normal engage position cannot be returned to, cause the situation of causing danger.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Light Crawler Tractor steering gear, and its reasonable in design, structure are simple, reliable operation, not easily get loose, and turning efficiency is good.
The present invention is the technical scheme solving the employing of its technical matters: a kind of Light Crawler Tractor steering gear, comprise wheel hub, the left end of described wheel hub is provided with a bull gear, described bull gear left end is to recessed, the first linkage section and the second linkage section is provided with inside described wheel hub left end, little gear ring is provided with on the right side of described wheel hub, be provided with a W groove between described bull gear and little gear ring, inside described wheel hub, a W groove bottom is also provided with a recessed structure to bull gear side for being carried out separating by two bearings be arranged in wheel hub.
Further, on a described W groove, the position at little gear ring top is provided with the 2nd W groove.
Good effect of the present invention is: the present invention is by said structure, so a kind of Light Crawler Tractor steering gear of the present invention, its reasonable in design, structure are simple, reliable operation, not easily get loose, and turning efficiency is good.
