Abstract
The utility model discloses a gear convenient to install, including the gear body, gear body center department is equipped with the mounting hole, and from interior to exterior is provided with the annular circle body of the different diameters of a plurality of in the mounting hole, passes through the key -type connection between the adjacent annular circle body. The utility model discloses a set up a plurality of annular circle bodies in the mounting hole at gear body center, can improve the installation effectiveness greatly so that when the transmission shaft with the different diameters of axle install, through getting inappropriate annular circle body, select the annular circle body of suitable internal diameter and transmission shaft to join in marriage the dress, nor it is reserve to need reprocessing to prepare the gear of multiple internal diameter mounting hole, has saved manufacturing cost.
Description
Technical field
The utility model belongs to gear technique field, particularly relates to a kind of gear being convenient to install.
Background technique
As everyone knows, gear is the highi degree of accuracy transmission part often used in machining production field, usual gear is mounted on transmission shaft, rotated by transmission shaft driven gear, and and then by gear pair transmission, because the diameter of axle of various transmission shaft is not identical, therefore, need select the gear with suitable center hole according to the diameter of axle of transmission shaft, this just makes the selection of gear and installs very loaded down with trivial details.
Summary of the invention
In order to solve Problems existing in background technique, the purpose of this utility model is to provide a kind of gear being convenient to install.
Be convenient to the gear installed, comprise gear, gear center is provided with mounting hole, is provided with the annular body of several different-diameters in mounting hole from the inside to the outside, is connected between adjacent annular circle body by key.
Further, the internal diameter being positioned at the annular body in outside in two adjacent annular body is consistent with the external diameter of the annular body being positioned at inner side.
Further, the internal diameter being positioned at the annular body of inner side is provided with keyway.
Further, annular ring body at least arranges 2.
Owing to adopting technique scheme, the utility model has following superiority:
The utility model by arranging multiple annular body in the mounting hole at gear center, can make when installing from the transmission shaft of the different diameter of axle, by taking down inappropriate annular body, the annular body of suitable inner diameter and transmission shaft is selected to be equipped with, substantially increase installation efficiency, nor need the gear of the multiple internal diameter mounting hole of reprocessing preparation for subsequent use, save cost of production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, gear; 2, annular body; 3, keyway.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of gear being convenient to install, comprise gear 1, gear 1 center is provided with mounting hole, is provided with the annular body 2 of several different-diameters from the inside to the outside, is connected between adjacent annular circle body 2 by key in mounting hole.
The internal diameter being positioned at the annular body in outside in two adjacent annular body 2 is consistent with the external diameter of the annular body being positioned at inner side.
The internal diameter being positioned at the annular body 2 of inner side is provided with keyway 3.
Annular ring body at least arranges 2.
The utility model by arranging multiple annular body in the mounting hole at gear center, can make when installing from the transmission shaft of the different diameter of axle, by taking down inappropriate annular body, the annular body of suitable inner diameter and transmission shaft is selected to be equipped with, substantially increase installation efficiency, nor need the gear of the multiple internal diameter mounting hole of reprocessing preparation for subsequent use, save cost of production.
