Abstract
The utility model belongs to the technical field of machinery and particularly relates to a driving gear which solves the problem of unreasonable design in the prior art. The driving gear comprises a gear body with a plurality of teeth, and is characterized in that a connecting column is arranged at one end of the gear body and is integrated with the gear body, a connecting blind hole is arranged at the center of the connecting column, and the height of the gear body is equal to that of the connecting column. Compared with the prior art, the driving gear has the advantages of reasonable design, simple structure, convenience in mounting, high mounting precision, wear resistance and high bearing capacity.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of actuation gear.
Background technique
Gear is a kind of common mechanical parts, and its structural type is varied, like various forms such as spur wheel, angular gear, bevel gear, worm screws, is widely used in the every field in production, the life.As everyone knows, gear is the vitals in the transmission device, need during installation that high installation precision becomes reconciled to disposition, but there is inconvenient installation in common gear, easy to wear, contact ratio is low, problems such as installation precision difference.
In order to solve the problem that existing technology exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example; The Chinese patent document discloses a kind of gear [application number: 200720159453.4], comprises gear shaft, key, it is characterized in that being installed on the gear shaft through key by a plurality of spur gear sheets; The spur gear sheet is successively around axial rotation, and the tooth between adjacent straight gear sheet is interlaced.
Such scheme has been alleviated the problem of contact ratio and overlap ratio difference to a certain extent, but still exists: complex structure, and inconvenient installation, easy to wear, technical problems such as installation precision difference.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provide a kind of reasonable in design, easy for installation, precision is high, anti abrasive actuation gear.
For achieving the above object, the utility model has adopted following technical proposal: this actuation gear comprises the gear mass with some teeth; It is characterized in that; One end of described gear mass is provided with attachment post, and described attachment post and gear mass are connected as a single entity, and is provided with attachment hole at the center of attachment post; Described attachment hole is a blind hole, and the height of described gear mass equates with the height of attachment post.
In above-mentioned actuation gear, the two ends of described teeth are respectively equipped with chamfer surface, and the top of teeth has the plane.
In above-mentioned actuation gear, the end of described attachment post is provided with annular guide face.
Compared with prior art, the advantage of this actuation gear is: 1, reasonable in design, simple in structure, easy for installation; 2, installation precision is high, and wear-resistant, bearing capacity is strong.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, gear mass 1, teeth 11, chamfer surface 111, plane 112, attachment post 2, attachment hole 21, annular guide face 22.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in Figure 1, this actuation gear comprises the gear mass 1 with some teeth 11; One end of gear mass 1 is provided with attachment post 2, and attachment post 2 is connected as a single entity with gear mass 1, is provided with attachment hole 21 at the center of attachment post 2; Attachment hole 21 is a blind hole, and the height of gear mass 1 equates with the height of attachment post 2.Attachment post 2 is provided with blind hole, and is easy for installation, and installation precision is high and good to disposition.
The two ends of teeth 11 are respectively equipped with chamfer surface 111, and the top of teeth 11 has plane 112.The end of attachment post 2 is provided with annular guide face 22.
This actuation gear is easy for installation, and precision is high, and is wear-resistant, and bearing capacity is strong and stability is strong.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as gear mass 1, teeth 11, chamfer surface 111, plane 112, attachment post 2, attachment hole 21, annular guide face 22 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
