Abstract
The utility model discloses a gear which comprises a gear body and clamping grooves. The clamping grooves are two in number and are symmetrically distributed in the inner side of the gear body, and a clamp spring groove is arranged in the inner side of the gear body. The gear has the advantages of being firm, little in abrasion and long in service life. The two symmetrically distributed clamping grooves are arranged so that the center of gravity of the gear is overlapped with the axis of the gear; in high-speed rotation, centrifugal force does not occur, and therefore abrasion between the clamping grooves and a shaft is reduced; and due to the fact that a clamp spring is arranged on the clamp spring groove in the inner side of the gear body, a positioning function on the gear is achieved, and the gear is prevented from being deviated when working.
Description
Technical field
The utility model belongs to mechanical transmission fields, is specifically related to a kind of gear.
Background technique
For gear is rotated, a draw-in groove is set in the gear inboard usually, be used with axle again, yet, after use a period of time, particularly in the very high use field of rotating speed, wearing and tearing meeting between this gear draw-in groove and the axle is very serious, causes the large minimizing of gear life, and this is because gear center of gravity and axis deviation, produce centrifugal force during rotation, accelerated the wearing and tearing of draw-in groove.
The model utility content
The purpose of this utility model is the problem that solves the wearing and tearing of said gear draw-in groove, and a kind of anti abrasive gear is provided.
The technological scheme that the above-mentioned purpose that realizes the utility model adopts is as follows:
A kind of gear comprises gear body, draw-in groove, and its characteristics are: draw-in groove is provided with two, and it is inboard to be symmetrically distributed in the gear body.
Further, be provided with jump-ring slot in gear body inboard.
Beneficial effect: gear of the present utility model has firmly, the characteristics of wearing and tearing, long service life, it is to adopt two symmetrical draw-in grooves, makes center of gravity and the axis coinciding of gear, when High Rotation Speed, can not produce centrifugal force, thereby reduce the wearing and tearing between draw-in groove and the axle; Jump-ring slot in gear body inboard is installed jump ring, and gear is played the role of positioning, and when preventing work, gear produces skew.
Description of drawings
Fig. 1 is gear structure schematic representation of the present utility model;
Fig. 2 is the sectional view of gear A-A face;
Wherein, 1-gear body, 2-tooth, 3-draw-in groove, 4-jump-ring slot.
Embodiment
Following structure drawings and Examples are described in further details the utility model.
A kind of gear comprises gear body 1, tooth 2, draw-in groove 3, and gear body 1 is ring-type, and tooth 2 is distributed in gear body 1 outside, and draw-in groove 3 is provided with two, and draw-in groove 3 is identical with the axle direction of gear body 1, and is symmetrically distributed in gear body 1 inboard.
A kind of gear, structure such as embodiment 1, difference are that the end in gear body 1 inboard also is provided with jump-ring slot 4.
Claims (1)
1. a gear comprises gear body, draw-in groove, it is characterized in that: draw-in groove is provided with two, and it is inboard to be symmetrically distributed in the gear body; Be provided with jump-ring slot in gear body inboard.
