Abstract
The invention discloses a cast gear comprising a gear body. An outer ring of the gear body is provided with gear teeth. The gear teeth and the gear body are integrated. The middle of the gear body is provided with a shaft hole provided with key grooves. The middle of the gear body is evenly provided with three connection holes and a bearing stepped hole. Different bearing materials can be added according to different rotational inertia requirements by setting the bearing stepped hole in the cast gear, and application requirements are met; the surface of each gear tooth is provided with an anti-sticking layer, and common gear surface wear and sticking can be avoided effectively for gears.
Description
Technical field
The present invention relates to cast manufacture field, relate in particular to a kind of cast gear.
Background technique
Gear (Gear) is the colyliform mechanical parts that rely on the engagement transmitting torque of tooth.Gear by with other dentation mechanical parts (as another gear, tooth bar, worm screw) transmission, can realize and change rotating speed and moment of torsion, change the function such as moving direction and change forms of motion.Due to advantages such as transmission efficiency are high, velocity ratio is accurate, power range is large, gear mechanism extensive use in industrial products, its design and manufacture level directly have influence on the quality of industrial products.Gear tooth mutually fastens gear and can drive another gear to rotate to transmit power.By two gears separately, also can apply chain, crawler belt, belt drives the gear on both sides and transmits power.Along with the raising of domestic mechanical level, also more and more higher to the requirement of gear, especially along with standardized propelling, need to there is the good gear of interchangeability, thereby meet the demand of different industries.
Summary of the invention
In order to meet above-mentioned situation, the object of this invention is to provide a kind of cast gear.
The present invention takes following technological scheme to realize: a kind of cast gear, comprise gear body, described gear body is provided with the gear teeth along outer ring, and the gear teeth and gear body are integral type structure, in the middle of described gear body, be provided with axis hole, on axis hole, be provided with keyway; Described gear body middle part is evenly provided with three attachment holes and a heavy burden step hole.
The described gear teeth adopt generating method to form, and tooth surface is provided with anti-stick layer.
The present invention has following beneficial effect in sum: cast gear of the present invention can add different heavy burden materials according to different rotary inertia requirements by heavy burden step hole is set, meet usage requirement, and tooth surface is provided with anti-stick layer, can effectively avoid the common tooth surface abrasion of gear and bonding.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1, the gear teeth; 2, gear body; 3, heavy burden step hole; 4, axis hole; 5, attachment hole; 6, keyway.
Embodiment
As shown in Figure 1, a kind of cast gear, comprises gear body 2, and described gear body 2 is provided with the gear teeth 1 along outer ring, and the gear teeth 1 and gear body 2 are integral type structure, in the middle of described gear body 2, is provided with axis hole 4, is provided with keyway 6 on axis hole 4; Described gear body 2 middle parts are evenly provided with three attachment holes 5 and a heavy burden step hole 3.
The described gear teeth 1 adopt generating method to form, the gear teeth 1 surface is provided with anti-stick layer, heavy burden step hole 3 can require to add different heavy burden materials according to different rotary inertias, meet usage requirement, and the gear teeth 1 surface is provided with anti-stick layer, can effectively avoid the common tooth surface abrasion of gear and bonding.
Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technological scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in claim scope of the present invention.
Claims (2)
