Abstract
The utility model discloses a double-side transmission eccentric gear, which comprises a double-side transmission gear and two eccentric bodies (1). The two eccentric bodies (1) are respectively welded to two end faces of the double-side transmission gear. The double-side 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 bilateral transmission eccentricity gear.
Background technique
The bilateral transmission eccentricity gear of prior art comprises a bilateral driving gear and two eccentric bodies, and two described eccentric bodies are located at respectively the both ends of the surface of bilateral driving gear; Described two eccentric bodies and bilateral driving gear are structure as a whole, and are cast and are formed by integrated type.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 bilateral 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 bilateral transmission eccentricity gear of prior art poor.Therefore, for these reasons, urgently need the bilateral 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 bilateral 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 bilateral transmission eccentricity gear is provided, and comprises a bilateral driving gear and two eccentric bodies, and two described eccentric bodies are welded on respectively in the both ends of the surface of bilateral driving gear; Described bilateral driving gear comprises the Double gear-ring that two blocks of webs, an outer ring, an interior ring and a Ultrastrength Steel are made, the outer ring of described web and Double gear-ring welding, the inner ring of described web and the welding of outer ring; Described interior ring is socketed in outer ring; Weld with two eccentric bodies respectively at the two ends of described outer ring, interior ring.
The outer end of described two eccentric bodies is all welded with an end plate.
On the outer surface of described two blocks of webs, be all welded with a balancing weight.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
Two eccentric bodies of the bilateral transmission eccentricity gear of the utility model are welded on respectively in the both ends of the surface of bilateral driving 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 bilateral 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 bilateral transmission eccentricity gear of the utility model better.Described bilateral driving gear comprises the Double gear-ring that two blocks of webs, an outer ring, an interior ring and a Ultrastrength Steel are made, the outer ring of described web and Double gear-ring welding, the inner ring of described web and the welding of outer ring; Described interior ring is socketed in outer ring; Weld with two eccentric bodies respectively at the two ends of described outer ring, interior ring.By the steel part of unlike material is welded, effectively increase the intensity of eccentricity gear, thereby improved to a certain extent the quality of product of bilateral transmission eccentricity gear.
As improvement, the outer end of described two eccentric bodies is all welded with an end plate.Effectively increase the axial length of eccentricity gear by end plate, thereby improved to a certain extent the assembling of bilateral transmission eccentricity gear.
As improvement, on the outer surface of described two blocks of webs, be all welded with a balancing weight.Effectively increase the stability of eccentricity gear by balancing weight, thereby improved to a certain extent the functional reliability of bilateral transmission eccentricity gear.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of bilateral transmission eccentricity gear of the utility model, comprises a bilateral driving gear and two eccentric bodies 1, and two described eccentric bodies 1 are welded on respectively in the both ends of the surface of bilateral driving gear.
Described bilateral driving gear comprises the Double gear-ring 5 that two blocks of webs 2, an outer ring 3, an interior ring 4 and a Ultrastrength Steel are made, and the outer ring of described web 2 and Double gear-ring 5 weld, and the inner ring of described web 2 and outer ring 3 are welded; Described interior ring 4 is socketed in outer ring 3; Weld with two eccentric bodies 1 respectively at described outer ring 3, the two ends of interior ring 4.
The outer end of described two eccentric bodies 1 is all welded with an end plate 6.
On the outer surface of described two blocks of webs 2, be all welded with a balancing weight 7.
In the present embodiment, the material of Double gear-ring 5 is 42CrMo, and the material of eccentric body 1, web 2, outer ring 3, interior ring 4, end plate 6, balancing weight 7 is A235-A or Q355.
Below be only described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
