Abstract
The utility model provides a planting a gear structure for automobile staring, being provided with the first slope structure of slope on the terminal surface of the teeth of a cogwheel, first slope structure is side direction slope structure, and the inclination more than or equal to 30 degree of first slope structure, and the first slope shared face area of structure is greater than 12 of this terminal surface whole area. Combination gear in order to solve in the present starter makes the wheel tooth top of two gears be in the same place with flywheel engaged with in -process easily, leads to the fact the dead trouble of card, and damages the problem of the teeth of a cogwheel easily. The utility model belongs to the automobile field.
Description
Technical field
The utility model relates to a kind of gear, belongs to automotive field.
Background technology
Automobile starter, it is the important parts that automobile is indispensable, when starting automobile, promote the combination gear in starter vertically, it is made to be meshed with flywheel, rotated by combination gear flywheel driven and realize automobile starting, draw back out after startup combination gear, at present, in the process promoting the combination gear in starter to be meshed with flywheel, usually there is the situation of the tooth of combination gear together with the tooth top in flywheel, make combination gear cannot continue vertically motion and engage with flywheel, cannot start by flywheel driven, cause stuck fault, the gear teeth of combination gear or flywheel are if things go on like this also easily caused to damage, cause unnecessary loss.
Summary of the invention
The purpose of this utility model is: provide a kind of gear structure for automobile starting, the process being meshed with flywheel with the combination gear solved in existing starter easily make together with the gear teeth of two gears withstand on, cause stuck fault, and easily damage the problem of the gear teeth.
For solving the problem, intend adopting a kind of like this gear structure for automobile starting, the end face of the gear teeth is provided with the first ramp structure of inclination, first ramp structure is side direction incline structure, and first the angle of inclination of ramp structure be more than or equal to 30 degree, shared by the first ramp structure, end face area is greater than the 1/2 of this end face total area;
The combination gear of automobile starter is identical with above-mentioned gear teeth structure with the gear teeth structure of the binding end of flywheel;
The end face of the gear teeth is also provided with the 2nd ramp structure that angle of inclination is greater than the first ramp structure on the basis of the first ramp structure;
2nd ramp structure is also side direction incline structure, and the inclination number of degrees of the 2nd ramp structure are between 35-70 degree.
The utility model is compared with prior art, major advantage adopts this gear teeth structure can make automobile starter in use, only need to use very little thrust that combination gear just can be made to engage fast with Automobile flywheel, thus start automobile, even if two gears are in conjunction with hour wheel tooth top together, also because of two groups of ramp structures, two gears can be relatively rotated and perfect engagement automatically, avoid the generation of the problem such as stuck, increase gear work-ing life, reduce maintenance cost and failure rate.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the gear teeth in gear described in the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right view of Fig. 1;
The combination gear that Fig. 4 is automobile starter moves with the structural representation (combination gear of automobile starter and the gear teeth structure of Automobile flywheel binding end are gear teeth structure described in the utility model) of engagement process to free wheel direction;
Wherein, Reference numeral 4 is flywheel, and Reference numeral 5 is the combination gear of automobile starter.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below with reference to accompanying drawings the utility model is described in further detail,
Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present embodiment provides a kind of for the gear structure of automobile starter and flywheel, the end face of the gear teeth 1 is provided with the first ramp structure 2 of inclination, first ramp structure 2 is side direction incline structure, and first the angle of inclination of ramp structure 2 be 45 degree, end face area shared by first ramp structure 2 is greater than the 1/2 of this end face total area, the end face of the gear teeth 1 is also provided with the 2nd ramp structure 3 that angle of inclination is greater than the first ramp structure 2 on the basis of the first ramp structure 2, 2nd ramp structure 3 is also side direction incline structure, and the 2nd the inclination number of degrees of ramp structure 3 be 60 degree.
