Abstract
The utility model discloses a unilateral-transmission eccentric gear which comprises a gear body and an eccentric body (1). The eccentric body (1) is welded on one end face of the gear body. The unilateral-transmission eccentric gear is low in production cost and good in product quality.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, is specifically a kind of monolateral transmission eccentricity gear.
Background technique
The monolateral transmission eccentricity gear of prior art comprises a gear and an eccentric body, and described eccentric body is located at an end face of gear; Described eccentric body and gear are structure as a whole, and by integrated type, are cast and are formed.Because integrated type is cast, required manufacture cost is high, the cycle is long, technique is loaded down with trivial details, yield rate is not high and a secondary casting die can only be cast a kind of product of specification, thereby causes the cost of production of monolateral transmission eccentricity gear of prior art higher.In addition, because the product of casting is prone to sand holes, thereby cause the quality of product of monolateral transmission eccentricity gear of prior art poor.Therefore, for these reasons, urgently need the monolateral transmission eccentricity gear of the low and good product quality of a kind of cost of production, to address the above problem.
Model utility content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, and the monolateral transmission eccentricity gear of the low and good product quality of a kind of cost of production is provided.
The technical solution of the utility model is, a kind of monolateral transmission eccentricity gear is provided, and comprises a gear and an eccentric body, and described eccentric body is welded on an end face of gear.
Described gear comprises a web, the many gear rings that connecting tendon, a wheel hub and a Ultrastrength Steel are made, the outer ring of described web and gear ring welding, the inner ring of described web and hub welding; One end of described many connecting tendons all with gear ring welding, the other end of described many connecting tendons is all and hub welding.
Described eccentric body is welded on web.
Between described eccentric body and gear, be also provided with a dunnage, the outer ring face of described dunnage and the welding of the inner ring face of eccentric body, the wheel hub outer ring face welding of the inner ring face of described dunnage and gear.
Between described eccentric body and gear, be also provided with many stiffening ribs, an end face of every stiffening rib all welds with the inner ring face of eccentric body, and all weld with the wheel hub outer ring face of gear the other end of every stiffening rib; Described stiffening rib also welds with the end face of dunnage.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
The eccentric body of the monolateral transmission eccentricity gear of the utility model is welded on an end face of gear, eccentricity gear with integrally casting is compared, its low cost of manufacture, the cycle is short, technique is simple, yield rate is low and be easy to make the product of plurality of specifications, thereby makes the cost of production of the monolateral transmission eccentricity gear of the utility model lower.In addition, because both are for being welded to connect, therefore there is not the problem of sand holes yet, thereby make the quality of product of the monolateral transmission eccentricity gear of the utility model better.
As improvement, described gear comprises a web, the many gear rings that connecting tendon, a wheel hub and a Ultrastrength Steel are made, the outer ring of described web and gear ring welding, the inner ring of described web and hub welding; One end of described many stiffening ribs all with gear ring welding, the other end of described many stiffening ribs is all and hub welding.By the steel part of unlike material is welded, effectively increased the intensity of eccentricity gear, thereby improved to a certain extent the quality of product of monolateral transmission eccentricity gear.
As improvement, between described eccentric body and gear, be also provided with a dunnage, the outer ring face of described dunnage and the welding of the inner ring face of eccentric body, the wheel hub outer ring face welding of the inner ring face of described dunnage and gear.By dunnage, effectively increase the intensity of eccentricity gear, thereby improved to a certain extent the quality of product of monolateral transmission eccentricity gear.
As improvement, between described eccentric body and gear, be also provided with many stiffening ribs, an end face of each stiffening rib all welds with the inner ring face of eccentric body, and all weld with the wheel hub outer ring face of gear the other end of each stiffening rib; Described stiffening rib also welds with the end face of dunnage.By stiffening rib, effectively increase the intensity of eccentricity gear, thereby improved to a certain extent the quality of product of monolateral transmission eccentricity gear.
