Abstract
The invention discloses a gear. The gear comprises a gear body, a shaft hole and a gear ring, the shaft hole is located in the center of the gear body, the gear body comprises a left half gear and a right half gear, the axial inner cross sections of the left half gear and right half gear are oppositely provided with slots and bumps, the left half gear and right half gear are firmly connected through the slots and bumps, and an arc-shaped through hole is formed in the gear body between the shaft hole and the gear ring. The gear is simple in structure, after the gear is damaged, an operator only needs to extract the bumps of one half gear from the slots of the other half gear, by means of the arc-shaped through hole, the gear can be held better, the gear weight is reduced, the manufacturing material is saved, and the energy consumption is saved in the transportation process.
Description
Technical field
The present invention relates to mechanical transmission fields, particularly a kind of gear.
Background technique
Gear transmission is most widely used a kind of type of belt drive in mechanical transmission.Existing plate-like gear is integrated mechanism, in Long-Time Service process, often damages, maintenance or more gear changing need axle to dismantle, then by gear shaft to dismounting, because the part between the axis hole of existing gear and peripheral gear ring is all solid construction, the deadweight of gear is very heavy on the one hand, and in the process changed, not easy to grip, easy landing, this dismounting and the process re-assemblied extremely bother, take time and effort, accidentally, gear landing can pound the foot of workman.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of new gear be convenient for changing.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of gear, comprise wheel body, axis hole and gear ring, described axis hole is positioned at wheel body center, described wheel body comprises left half wheel and right half wheel, a described left side half wheel and the axially interior cross section of right half wheel are relatively set with draw-in groove and lug boss, a described left side half wheel is fixedly connected with lug boss by draw-in groove with right half wheel, and the wheel body between described axis hole and gear ring is provided with arc-shaped through-hole.
Further, the number of described arc-shaped through-hole is four.
Further, described arc-shaped through-hole is evenly distributed on wheel body.
Structure of the present invention is simple, described gear is after damage, only the lug boss of one of them half wheel need be extracted out from the draw-in groove of another half wheel, increase arc-shaped through-hole and can grip gear better, and alleviate the weight of gear itself, save manufactured materials, also in transportation process, save energy consumption.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is a left side of the present invention half wheel and right half wheel construction schematic diagram;
Fig. 3 is sectional drawing of the present invention;
In figure: 1 is wheel body, 2 is axis hole, and 3 is left half wheel, and 4 is right half wheel, and 5 is draw-in groove, and 6 is lug boss, and 7 is gear ring, and 8 is arc-shaped through-hole.
Embodiment
A kind of gear, comprise wheel body 1, axis hole 2 and gear ring 7, described axis hole 2 is positioned at wheel body 1 center, described wheel body 1 comprises left half wheel 3 and right half wheel 4, a described left side half wheel 3 and the axially interior cross section of right half wheel 4 are relatively set with draw-in groove 5 and lug boss 6, a described left side half wheel 3 is fixedly connected with lug boss 6 by draw-in groove 5 with right half wheel 4, wheel body 1 between described axis hole 2 and gear ring 7 is provided with arc-shaped through-hole 8, the number of described arc-shaped through-hole 8 is four, and described arc-shaped through-hole 8 is evenly distributed on wheel body 1.
Structure of the present invention is simple, described gear is after damage, only the lug boss of one of them half wheel need be extracted out from the draw-in groove of another half wheel, increase arc-shaped through-hole and can grip gear better, and alleviate the weight of gear itself, save manufactured materials, also in transportation process, save energy consumption.
Claims (3)
1. a gear, comprise wheel body, axis hole and gear ring, described axis hole is positioned at wheel body center, described wheel body comprises left half wheel and right half wheel, it is characterized in that, a described left side half wheel and the axially interior cross section of right half wheel are relatively set with draw-in groove and lug boss, and a described left side half wheel and right half is taken turns and is fixedly connected with lug boss by draw-in groove, and the wheel body between described axis hole and gear ring is provided with arc-shaped through-hole.
2. a kind of gear according to claim 1, is characterized in that, the number of described arc-shaped through-hole is four.
3. a kind of gear according to claim 1, is characterized in that, described arc-shaped through-hole is evenly distributed on wheel body.
