Abstract

The invention discloses a wear-resistant casting gear which is composed of a gear body, gear teeth and a shaft hole. Four key grooves are arranged at the shaft hole of the gear body, a wear-resistant layer is arranged on the surface of each gear tooth, an oilway is arranged between a gear ring and the shaft hole, a through hole is arranged on an outer wall, taking the shaft hole as a center, of the gear body, and a filling is arranged in the through hole. The wear-resistant casting gear has the advantages of convenience in use, flexibility in transmission, little wear, long service life and the like.

Description

A kind of wear-resistant cast gear
Technical field
The present invention relates to a kind of mechanically operated component, relate in particular to a kind of wear-resistant cast gear.
Background technique
At present, along with developing rapidly of industry, various big machineries are used, and as the gear of bindiny mechanism, its application area be also very extensively, general gear is because material difference or structural design is unreasonable, in use not only make gear surface be subject to grievous injury, more can cause mechanical damage, thereby affect working efficiency, cause the loss that is difficult to retrieve.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of wear-resistant cast gear.
The present invention takes following technological scheme to realize: a kind of wear-resistant cast gear, and it is to be made up of gear body, teeth and axis hole, the axis hole place of described gear body is provided with four keyways; Described teeth surface is provided with wearing layer; Between described gear ring and axis hole, be provided with oil duct; On the outer wall of described gear body centered by axis hole, be provided with through hole; In described through hole, be provided with packing; Described four keyways evenly arrange along the cylindrical of axis hole; The thickness of described wearing layer is 0.3 ~ 3mm.
The present invention has following beneficial effect in sum: cast gear of the present invention have easy to use, ensuring smooth transmission, wearing and tearing less with the advantages such as long service life.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, teeth; 2, oil duct; 3, through hole; 4, axis hole; 5, packing; 6, keyway; 7, wearing layer; 8, gear body; 9, gear ring.
Embodiment
As shown in Figure 1, a kind of wear-resistant cast gear, it is to be made up of gear body 8, teeth 1 and axis hole 4, axis hole 4 places of described gear body 8 are provided with four keyways 6; Described teeth 1 surface is provided with wearing layer 7; Between described gear ring 9 and axis hole 4, be provided with oil duct 2; On the outer wall of described gear body 8 centered by axis hole 4, be provided with through hole 3; In described through hole 3, be provided with packing 5; Described four keyways 6 evenly arrange along the cylindrical of axis hole 4; The thickness of described wearing layer 7 is 0.3 ~ 3mm.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
