Abstract
The utility model relates to a kind of same shaft coupling structures of the reduction gearing of press machine, including large diameter gear and small-diameter gear, one end of the small-diameter gear is central axial to be provided with connecting shaft, the connecting shaft is inserted into the end face of in the centre bore of large diameter gear and end face and large diameter gear, there are several corresponding axial half-arc grooves around circumference on the centre bore inner sidewall of the large diameter gear and the lateral wall of connecting shaft, it is axially inserted into the jack of corresponding axial direction half-arc groove composition and is disposed with attachment pegs realization interference fit, it is also axial between the centre bore of the connecting shaft and large diameter gear to be connected with screw.The utility model structure is simple, couples large diameter gear and small-diameter gear in such a way that axial bolt and screw are fixed, and be not take up the radial space of gear, ensure that the fastness coupled between gear.
Description
Technical field
The utility model relates to press machine fields, more particularly to a kind of same shaft coupling structure of reduction gearing of press machine.
Background technique
Press machine is usually used in pressing process and block pressing forming process, in the internal drive structure of press machine, reduction gearing
Be it is more commonly used, wherein double reduction gearing is also common component, in order to reduce the size of gear-box, it is desirable to reduce two-stage
The coupling structure of large diameter gear and small-diameter gear in reduction gearing, with the installation space of gear-box.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of same shaft coupling structure of the reduction gearing of press machine, knots
Structure is simple, couples large diameter gear and small-diameter gear in such a way that axial bolt and screw are fixed, and be not take up the diameter of gear
To space, the fastness coupled between gear ensure that.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the reduction gearing for providing a kind of press machine is same
Shaft coupling structure, including large diameter gear and small-diameter gear, one end of the small-diameter gear is central axial to be provided with connecting shaft, institute
The connecting shaft stated is inserted into the end face of in the centre bore of large diameter gear and end face and large diameter gear, the large diameter gear
There are several corresponding axial half-arc grooves around circumference on centre bore inner sidewall and the lateral wall of connecting shaft, relatively
It is axially inserted into the jack for the axial half-arc groove composition answered and is disposed with attachment pegs and realizes interference fit, the connecting shaft and big
It is also axial between the centre bore of diameter gear to be connected with screw.
As a kind of supplement to technical solution described in the utility model, the end face of the attachment pegs has been centrally located
Screw connecting hole.
The utility model has the advantages that structure is simple the utility model relates to a kind of reduction gearing of press machine same shaft coupling structure, use
Axial bolt and screw fixed mode couples large diameter gear and small-diameter gear, and is not take up the radial space of gear, guarantees
The fastness coupled between gear.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figs. 1-2, the technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of press machine
The same shaft coupling structure of reduction gearing, including large diameter gear 1 and small-diameter gear 2, one end of the small-diameter gear 2 be central axial
It is provided with connecting shaft 5, the connecting shaft 5 is inserted into the centre bore of large diameter gear 1 and end face and the end face of large diameter gear 1 are neat
It is flat, there are several opposite around circumference on the centre bore inner sidewall of the large diameter gear 1 and the lateral wall of connecting shaft 5
The axial half-arc groove answered is axially inserted into and is disposed with attachment pegs 4 in the jack of corresponding axial direction half-arc groove composition, described
It is also axial between connecting shaft 5 and the centre bore of large diameter gear 1 to be connected with screw 3.
The end face of the attachment pegs 4 has been centrally located screw connecting hole 6.
The utility model structure is simple, couples large diameter gear and path tooth in such a way that axial bolt and screw are fixed
Wheel, and it is not take up the radial space of gear, it ensure that the fastness coupled between gear.
