Abstract
The utility model relates to a gear, including the gear body, gear body middle part is equipped with the shaft hole, and the circumference of gear body is equipped with a plurality of sawtooth, its characterized in that: the gear body including outer lane that the steel of components of a whole that can function independently setting becomes, set up the inner circle that the aluminum alloy in the outer lane was made, the shaft hole circle including setting up, the sawtooth setting outer lane week upwards, inner circle, outer lane fixed connection. The present invention uses the technical scheme, the utility model provides a gear, its quality is light, and is with low costs, has saved the resource greatly.
Description
Technical field
The utility model relates to a kind of gear.
Background technique
Existing gear is formed in one, and in order to ensure that it has enough intensity, it is generally steel and makes, and it includes gear, be provided with axis hole in the middle part of gear, gear be circumferentially with some sawtooth, but, the gear of this structure, its quality is large, and cost is high, causes the waste of resource.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of gear, its quality is light, and cost is low, greatly saves resource.
The technical solution of the utility model: a kind of gear, include gear, axis hole is provided with in the middle part of gear, gear be circumferentially with some sawtooth, it is characterized in that: described gear includes the inner ring that outer ring, the aluminum alloy be arranged in outer ring that steel that split arranges makes are made, described axis hole is arranged on inner ring, and sawtooth is arranged in the circumference of outer ring, and described inner ring, outer ring are fixedly connected with.
Adopt technique scheme, the inner ring that aluminum alloy is made, makes gear, and its quality is light, and cost is low, greatly saves resource; The gear of this structure is easy for installation, and structure is simple.
Further setting of the present utility model a: side end face of described inner ring offers groove along its outer periphery, described outer ring has extended internally location piece, and described location piece extends in groove, and location piece and bottom portion of groove are fixed through locating piece.
Adopt above-mentioned further setting, this inner ring, outer ring means of fixation, make gear structure compact, and it is firm to locate, and, the service behaviour of gear can not be affected.
Setting further more of the present utility model: described inner ring offers some lightening holes.
Adopt and above-mentionedly to arrange further again, the lightening hole of setting, can alleviate the quality of gear further, saves material.
Further setting more of the present utility model: described lightening hole includes around inner ring axially equally distributed first lightening hole, the second lightening hole, second lightening hole is arranged between adjacent first lightening hole, the first described lightening hole is triangle, and the second described lightening hole includes the second circular lightening hole, the second oval lightening hole.
Adopt and above-mentionedly further to arrange again, this lightening hole set-up mode, can ensure that gear has enough intensity, its service behaviour can not be affected, can alleviate quality again.
Further setting more of the present utility model: described groove is axially uniformly distributed around inner ring and is positioned at outside the second oval lightening hole.
Adopt and above-mentionedly further to arrange again, the groove set-up mode of this structure, makes stable gear, stable performance.
