Abstract
The invention discloses a gear. The gear comprises a gear body, wherein a shaft hole is formed in the center of the gear body, circular bosses are symmetrically arranged on the end faces of the two sides of the gear body respectively, four through holes which are evenly distributed in an annular mode are further formed in the gear body, and the four through holes are formed in the outer sides of the circular bosses and the inner side of a gear ring of the gear body. According to the gear, due to the fact that the four through holes which are evenly distributed in the annular mode are formed in the gear body, the weight of the gear body can be reduced through the four through holes; the four through holes can serve as datum holes for machining locating so that the shaft hole in the center and the gear ring on the outer circle can be machined; the four through holes can serve as datum holes for installation locating so that the gear can be installed, and machining accuracy and installation accuracy of the gear can be ensured.
Description
Technical field
The present invention relates to mechanical transmission component, particularly a kind of gear of splined hole.
Background technique
In the production of gear and the process of installation, because external toothing and the interior axis hole of gear are all to have strict matching requirements, if so process other parts using it as fixed position, can affect to machining accuracy, and size produces after certain deviation and be difficult to repair, cause unnecessary scrapping.
Summary of the invention
The object of this invention is to provide a kind of processing and install and locate gear easily.
For solving the problems of the technologies described above, the invention provides a kind of gear, comprise gear body, center at described gear body is provided with axis hole, on the end face of the both sides of described gear body, be symmetrically arranged with round boss, on described gear body, be also provided with equally distributed four through holes of ring-type, described four through holes are positioned at the outside of described round boss and the gear ring of described gear body inner side.A kind of gear of the present invention, on gear body, be provided with equally distributed four through holes of ring-type, these four through holes not only can alleviate the weight of this province of gear, and the datum hole that can be used as processing location is processed middle axis hole and the gear ring of cylindrical, the datum hole that can be used as installation location is installed gear, ensures the processing of gear and the precision of installation.
Wherein, described four through holes are circular, in described four through holes, are also provided with one deck anti-skid wearable layer; Described axis hole is splined hole.Circular through hole balance is better, can not have influence on the rotation of gear, and the design of anti-skid wearable layer can improve positioning precision, extends the working life of through hole.
A kind of gear of the present invention, the location that meets processing and install by four through holes, effective, cost is low, on the both sides end face of gear body, symmetrically arranged round boss can increase the rotational strength of axis hole, makes whole gear be easy to processing, and durable in use.
