Description
Technical field
This utility model belongs to starter motor for internal combustion engine technical field, is specifically related to the roller location unidirectional planet of formula and subtracts
Speed device.
Background technology
Along with the development of engine starting machine technology, by direct-drive type starter to retarding starter, no matter eccentric
Slowing-down structure, or the starter of planetary reduction gear structure.Reducing gear and isolator are on same starter motor
The most axial arranged, play and reduce rotating speed increase moment of torsion and the purpose of one-way transmission torque startup electromotor.Existing
High in conventional roller type one way device fault rate, synchronicity that each roller rotates and the poor reliability being connected,
And starter complete machine structure is the compactest, length is difficult to shorten, and part vehicle cannot use, and therefore, rises
The miniaturization of motivation, lightweight, high-performance, long-life are following industry development directions.
Summary of the invention
The purpose of this utility model is that solution prior art starter length is longer, and structure is the compactest, unidirectional
The problem that device fault rate is high, it is provided that the roller location unidirectional planetary reduction gear of formula.
This utility model adopts the technical scheme that for solving above-mentioned technical problem:
The roller location unidirectional planetary reduction gear of formula, positions the unidirectional planetary reduction gear of formula including roller, including planet
Deceleration device and non-return device, be characterized in: described non-return device includes single retarded crust of the device, planet
Decelerator ring gear, roller；Single retarded crust of the device is enclosed within outside described planetary reduction gear ring gear；Described
Non-return device also includes roller positioner and torsionspring；Described roller is positioned at the rolling on roller positioner
In post groove, and it is placed in inwall and the planetary reduction gear internal tooth of single retarded crust of the device with roller positioner
Circle outer wall between gap in, wherein: the inwall average mark of single retarded crust of the device be furnished with some for
Accommodate the space of roller, formed between bottom and the outer wall of planetary reduction gear ring gear in this space and be enough to roll
The gradual change gap that post blocks；Described torsionspring one end is fixed on roller positioner, and the other end is fixed on
On single retarded crust of the device, torsionspring is installed after putting in place should keep the trend of opening, and makes whole roller all locate
In the position blocked.
Roller positioner uses metal material or plastic material manufacture.
This utility model compared with prior art, has the advantages that
Owing to this utility model uses planetary reducer is overlapping with non-return device, merge into the one of entirety
The unidirectional planetary reduction gear of starter, makes starter compact conformation, contraction in length, and non-return device uses roller fixed
Position device, it is ensured that the synchronicity that each roller rotates, the reliability that is connected, durability improve.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 planetary reduction gear ring gear；2 roller positioners；3 single retarded crusts of the device；
4 torsionsprings；5 rollers.
Detailed description of the invention
As it is shown in figure 1, the roller location unidirectional planetary reduction gear of formula, including planetary reducer and non-return device,
It is characterized in: described non-return device includes single retarded crust of the device 3, planetary reduction gear ring gear 1, roller
5；Single retarded crust of the device 3 is enclosed within outside described planetary reduction gear ring gear 1；Described non-return device also includes
Roller positioner 2 and torsionspring 4；Described roller 5 is positioned at the roller slot on roller positioner 2,
And inwall and the planetary reduction gear ring gear 1 of single retarded crust of the device 3 it is placed in roller positioner 2
Outer wall between gap in, wherein: the inwall average mark of single retarded crust of the device 3 be furnished with some for
Accommodate the space of roller 5, formed between bottom and the outer wall of planetary reduction gear ring gear 1 in this space and be enough to
The gradual change gap that roller 5 is blocked；Described torsionspring 4 one end is fixed on roller positioner 2, separately
One end is fixed on single retarded crust of the device 3, and torsionspring 4 is installed after putting in place should keep the trend of opening,
Whole roller 5 is made to be in the position blocked.
Roller positioner uses metal material or plastic material manufacture.
Operation principle:
During utility model works, the inwall that whole rollers 5 are positioned at single retarded crust of the device 3 subtracts with planet
Speed device ring gear 1 outer wall between gap in and be in the state of blocking, when planetary reduction gear ring gear 1 exists
When having rotation trend under overspeed condition, roller positioner 2 rotates backward, and roller 5 exits the state of blocking,
When being in normal activation state, roller 5 is in, under the effect of torsionspring, the state of blocking.
