Abstract
The utility model relates to an eccentric gear structure of a press machine, which belongs to the technical field of the components of the press machine. The eccentric gear structure is the improvement of the eccentric gear structure of the prior press machine, which is mainly characterized in that the original integrated cast structure is changed into a structure formed through welding a plurality of components of a gear ring, a connecting rib plate, an eccentric body, a middle rib plate, an eccentric sleeve and a reinforcing rib, and the eccentric body welded at the end part of the eccentric sleeve adopts various steel welding structures, therefore, the size of the profile is reduced, and the rate of finished products is improved, thereby the integrated performance of the press machine is greatly improved, and the manufacturing cost is reduced. The utility model has the advantages that the structure is simple and reasonable, the processing and the installation are convenient, and strong practicability and obvious economic efficiency are provided.
Description
Technical field
The utility model relates to a kind of press off-centering gear structure, belongs to press machine component technical field.
Background technique
Eccentricity gear is a kind of special construction part that eccentric structure and gear are united two into one, and is the kernel component of press machine transmission system, drives eccentric rod gear in transmitting large torque, drives slide block and does and pump.Existing eccentricity gear, usually adopt the cast inblock structure, along with increasing of increasing, small lot even the many kinds of single-piece of the increasing of the stroke of a press, nominal pressure, the needed die cost of original cast structure is very high, and also there is certain reject rate in casting, cause manufacture cost height, manufacturing cycle long, influenced the delivery date and the overall performance of press machine, the cast inblock structure of original eccentricity gear and manufacture method can not satisfy fast-developing demand.
Summary of the invention
The purpose of this utility model is because of deficiencies such as manufacture cost height, the manufacturing cycle of adopting the cast inblock structure to cause are long at the eccentricity gear in the existing press machine, provide and to organize production fast, can guarantee a kind of press off-centering gear structure that yield rate is very high again.
The purpose of this utility model is achieved through the following technical solutions, a kind of press off-centering gear structure, it is characterized in that described eccentricity gear is made of gear ring, connection gusset, eccentric body, middle gusset, eccentric bushing, stiffening rib, eccentric bushing end welding eccentric body, the cylindrical of eccentric bushing and be connected the endoporus welding of gusset connects the cylindrical welding gear ring of gusset.
Middle gusset is set, the cylindrical of middle gusset and the welding of eccentric bushing endoporus in the eccentric bushing.
The one end welding eccentric body of eccentric bushing, or two end part welding eccentric body.
Between gear ring and the eccentric bushing stiffening rib is set.
The utility model is the improvement to existing press off-centering gear structure, with original cast inblock structure, make into to constitute through welding by gear ring, connection gusset, eccentric body, middle gusset, eccentric bushing and a plurality of parts of stiffening rib, eccentric bushing end welding eccentric body adopts different steel welded structures, external dimension have been reduced, improved yield rate, thereby improved the overall performance of press machine greatly and reduced manufacture cost, the utility model is simple and reasonable, processing and assembling is convenient, has very strong practicability and tangible economic benefit.
Description of drawings
Accompanying drawing 1 is one of the utility model structural representation;
Accompanying drawing 2 is two of the utility model structural representation;
Accompanying drawing 3 is the left TV structure schematic representation of Fig. 1, Fig. 2;
In the accompanying drawing, 1 gear ring, 2 connect gussets, 3 eccentric bodies, gusset in 4,5 eccentric bushings, 6 stiffening ribs, 7 eccentric bodies.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as Fig. 1, shown in Figure 3, the utility model is by gear ring 1, eccentric bushing 5, connect gusset 2, middle gusset 4, stiffening rib 6 and eccentric body 3 and eccentric body 7 formations, gear ring 1 and eccentric bushing 5 by be connected gusset 2, stiffening rib 6 is welded into integral body, gusset 4 in the welding in the eccentric bushing 5, eccentric body 3,7 is welded on the two end part of eccentric bushing 5 respectively.
As Fig. 2, shown in Figure 3, according to the kind and the purposes of press machine, an end of eccentric bushing 5 welding eccentric body 3.
Load situation according to different parts adopts different steel to be welded, and gear ring 1 adopts medium carbon structural alloy steel, and eccentric bushing 5 adopts medium carbon structural steel, connection gusset 2, middle gusset 4, stiffening rib 6 to adopt the low-carbon (LC) structural carbon steels.
Claims (4)
1, a kind of press off-centering gear structure, it is characterized in that described eccentricity gear is made of gear ring, connection gusset, eccentric body, middle gusset, eccentric bushing, stiffening rib, eccentric bushing end welding eccentric body, the cylindrical of eccentric bushing and the endoporus welding that is connected gusset, the cylindrical of connection gusset welds gear ring.
2, press off-centering gear structure according to claim 1 is characterized in that being provided with in the eccentric bushing middle gusset, the cylindrical of middle gusset and the welding of eccentric bushing endoporus.
