Abstract
The utility model belongs to the technical field of machinery, and in particular relates to a modified form gear, solving the problems of the prior art, such as unreasonable design. The modified form gear comprises a gear body with a plurality of teeth which are uniformly distributed; the gear body is provided with a central hole in the centre; the central hole is internally provided with a ring step in an opening; the central hole is internally provided with a key slot; and a chamfered face is arranged at both ends of each tooth respectively. In comparison with the prior art, the modified form gear disclosed by the utility model has the advantages as follows: 1. reasonable design, simple structure and convenient installation; and 2. high overlap ratio, wear resistance and high bearing capacity.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of improved type 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, but that common gear exists is easy to wear, and contact ratio is low, problems such as bearing capacity difference and inconvenient installation.
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 exist: complex structure, inconvenient installation, technical problem such as easy to wear.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and a kind of reasonable in design, easy for installation, strong, anti abrasive improved type gear of stability is provided.
For achieving the above object; The utility model has adopted following technical proposal: this improved type gear, comprise gear mass with some even distribution teeth, and have center hole at the center of gear mass; It is characterized in that; Be provided with the ring-shaped step that is positioned at the place, aperture in the described center hole, be provided with keyway in the described center hole, be respectively equipped with chamfer surface at the two ends of each teeth.
In above-mentioned improved type gear, the top of described teeth has the plane.
Compared with prior art, the advantage of this improved type gear is: 1, reasonable in design, simple in structure, easy for installation; 2, contact ratio 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, center hole 2, ring-shaped step 21, keyway 22.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in Figure 1, this improved type gear comprises the gear mass 1 with some even distribution teeth 11; Has center hole 2 at the center of gear mass 1; Be provided with the ring-shaped step 21 that is positioned at the place, aperture in the center hole 2, be provided with keyway 22 in the center hole 2, be respectively equipped with chamfer surface 111 at the two ends of each teeth 11.Keyway 22 has made things convenient for the gear installation with ring-shaped step 21, and chamfer surface 111 has strengthened the wear resistance of gear.
The top of teeth 11 has plane 112.
This improved type gear is convenient to be installed, and contact ratio 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, center hole 2, ring-shaped step 21, keyway 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.
Claims (2)
1. improved type gear; Comprise gear mass (1) with some even distribution teeth (11); Have center hole (2) at the center of gear mass (1), it is characterized in that, be provided with the ring-shaped step (21) that is positioned at the place, aperture in the described center hole (2); Be provided with keyway (22) in the described center hole (2), be respectively equipped with chamfer surface (111) at the two ends of each teeth (11).
2. improved type gear according to claim 1 is characterized in that, the top of described teeth (11) has plane (112).
