Motor increasing gear component is generated electricity in transmission process is intermeshed, it can be because prolonged engaged transmission, causes to send out between gear
Raw abrasion, gear after abrasion is it is difficult to ensure that its normal effective operation, and for the gear assembly after abrasion, it is necessary to will be entire
Gear is replaced, more wasteful resource, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is that the defects of for the prior art and deficiency, provide a kind of simple in structure, design conjunction
Reason, wear-resisting generator speed increasing mechanism gear assembly easy to use can be reduced effectively between gear because intermeshing passes
It is dynamic and caused by degree of injury, and can be when gear engaging tooth be worn, removable parts structure, nothing needs to change entire tooth
Wheel, economizes on resources, practicability is stronger.
To achieve the above object, the technical solution adopted in the utility model is：It includes gear housing, gear wheel, small tooth
Wheel, shaft, small bearing, big bearing；The inside of gear housing is screwed with gear wheel and pinion gear, gear wheel and small tooth by shaft
Wheel intermeshing；The small bearing is socketed in the shaft for the pinion gear that is screwed on, and big bearing is socketed in the shaft of connection gear wheel
On；It also includes gear teeth protective case and fixed pin；The gear teeth protective case is socketed in gear wheel and the gear of pinion gear
On tooth, and fixed by fixed pin connection；The inward flange of the gear teeth protective case is equipped with installation fixed edge, installs fixed edge
And it is equipped with pin hole in gear wheel and pinion gear；The fixed pin is threaded through in pin hole.
Further, the sawtooth set outside left and right edges of the gear teeth protective case are equipped with silica gel protective pad.
Further, the silica gel protective pad is embedded in the sawtooth set of gear teeth protective case.
Further, buffer layer is equipped between the gear teeth protective case and gear wheel and the gear teeth of pinion gear.
Further, the buffer layer be silicagel pad or spongy layer, thickness 0.5-1.0mm.
With the above structure, the utility model has the beneficial effect that：A kind of wear-resisting generator described in the utility model
Speed increasing mechanism gear assembly can effectively reduce degree of injury caused by due to intermeshing transmission between gear, and can
When gear engaging tooth is worn, removable parts structure without entire gear is needed to change, economizes on resources, and practicability is stronger, this
Utility model has the advantages that simple in structure, it is reasonable to set, low manufacture cost.
