Abstract

The utility model relates to a combined herringbone gear, belonging to the part in the technical field of press and similar machining machine, which is mainly characterized in that the tooth ring at the periphery of the gear body comprises two portions, one portion is that the tooth ring at one side of over-travel groove is integrated with the gear body, the other portion is that the tooth ring at the other side of over-travel groove is fixed with tooth ring at one side of over-travel groove by a plurality of pins and bolts, the utility model changes the structure of tooth ring of the prior integrated herringbone gear and comprises the two portions, so that particular requirement of machining equipment is reduced greatly, the two portions are respectively machined, so a great deal of current gear machining equipment can be used to machine, accordingly the production cost is reduced to improve the machining precision of the gear, the utility model has convenient machining process and simple structure, and is applicable for the transmission member of press, punching machine and similar machining machine.

Description

The combined type herringbone gear

Technical field

The utility model relates to a kind of combined type herringbone gear, belongs to the parts in the working machine drive technology fields such as press machine.

Background technique

At press machine, the gear pair that has high-speed motion in the driving mechanism of working machines such as punch press, gearwheel in the gear pair is a herringbone gear, existing herringbone gear is an overall structure, the gear ring that comprises wheel body and periphery thereof, and grinding undercut, the lambdoid tooth in grinding undercut both sides, producing this integral herringbone gear has relatively high expectations to process equipment, generally need to adopt special device, we are domestic at present lacks this special processing equipment, because the particularity of the rare and processing of special processing equipment requires to make processing cost increase substantially, and existing machining accuracy also is difficult to guarantee.

Summary of the invention

The purpose of this utility model is the above-mentioned condition that exists during integral herringbone gear in processing at having now, the processing of providing convenience, helps reducing production costs and improves a kind of combined type herringbone gear of machining accuracy.

The purpose of this utility model is achieved through the following technical solutions, a kind of combined type herringbone gear, the gear ring that comprises wheel body and periphery thereof, and grinding undercut, the lambdoid tooth in grinding undercut both sides, the gear ring that it is characterized in that described wheel body periphery is made of two-part, and the gear ring of grinding undercut place one side and wheel body are one, and the gear ring of grinding undercut place opposite side is through the several pin of setting and the gear ring positioning and fixing of a screw and a side.

The utility model is by changing the overall structure of existing integral herringbone gear, oblique gear ring combination by two groups of different rotation directions, even constitute one admittedly through locating stud location, bolt, greatly reduce the specific (special) requirements to process equipment, two-part are processed respectively, existing a large amount of gear machining apparatus all can be competent at, thereby also reduced cost of production, and helping improving the machining accuracy of gear, the utility model is easy to process, simple in structure, be applicable to the driving mechanism of working machines such as press machine, punch press.

Description of drawings

Fig. 1 is the utility model sectional structure schematic representation;

Among the figure, 1 wheel body, 2 gear rings, 3 outer permanent tooth circles, 4 grinding undercuts, 5 pins, 6 screws.

Embodiment

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is made of the gear ring of wheel body 1, wheel body 1 periphery, gear ring comprises two-part, be grinding undercut 4 one sides be the gear ring 2 of one with wheel body 1, another part is the outer permanent tooth circle 3 of grinding undercut 4 opposite sides, with wheel body 1 be the plane for the gear ring 2 of one and the junction plane of outer permanent tooth circle 3, its junction plane place correspondence interval respectively is provided with pin-and-hole and screw, sell 5 and insert the pin-and-hole location, connect two gear rings admittedly through screw.

Claims

1, a kind of combined type herringbone gear, the gear ring that comprises wheel body and periphery thereof, and grinding undercut, the lambdoid tooth in grinding undercut both sides, the gear ring that it is characterized in that described wheel body periphery is made of two-part, the gear ring of grinding undercut place one side and wheel body are one, and the gear ring of grinding undercut place opposite side is through the several pin of setting and the gear ring positioning and fixing of a screw and a side.

2, combined type herringbone gear according to claim 1, the junction plane that it is characterized in that two gear rings is the plane.
