Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with specific embodiments and drawings, but not
Limit the protection scope of the utility model and embodiment.
Embodiment 1
A kind of one-way clutch gear set of the present embodiment, referring to figure 1 and figure 2, the one-way clutch gear set include master
Moving gear 1 and driven gear 2, driving gear 1 are overlapped with the pivot center of driven gear 2, and driving gear 1 and driven gear 2
Centre have so that gear is installed on the through-hole on gear shaft, the inner port edge of driving gear 1 has axially extended the first company
Socket part 11, driven gear 2 are arranged in the first connecting portion 11 for being mounted on driving gear 1.First connecting portion 11 is from driving gear 1
It extends out in the axial direction of inner port edge, and is arranged installation for driven gear 2, be conducive to further increase the whole of gear set
Body property simple for structure.
When driving gear 1 is rotated along a direction, it can be combined with driven gear 2 and drive driven gear 2 same in the same direction
Step rotation, and when the reversion of driving gear 1, driving gear 1 separates with driven gear 2 and driven gear 2 cannot be driven to rotate synchronously.
Wherein, when the one-way clutch gear set is applied to equipment, driving gear 1 engages connection, driven gear 2 with power source output terminal
Connection is engaged with drive output.In this way, driving gear 1 can be rotated and be combined drive with driven gear 2 when carrying out clutch transmission
Driven gear 2 rotates synchronously, and carries out torque transmission；After torque transmission, driving gear 1 invert, i.e., driving gear 1 with it is driven
Gear 2 separates, and driven gear 2 is not rotated synchronously with driving gear 1.
Specifically, referring to Fig. 3 a and Fig. 3 b, have on driving gear 1 around the distribution of the direction of rotation of first connecting portion 11,
And towards the spiral terrace 10 of 2 spiral salient of driven gear；And on driven gear 2 have with the spiral terrace 10 be adapted
Spiral groove 20, spiral groove 20 can be interlocked with the spiral terrace 10.Wherein, the raised most significant end end of spiral terrace 10
End face it is parallel with the pivot center of driving gear 1, corresponding, the groove bosom end face of spiral groove 20 and driven gear 2
Pivot center it is parallel, the end face of the raised most significant end end of spiral terrace 10 is with the groove bosom end face of spiral groove 20
Corresponding button bit, in the combination of spiral terrace 10 and spiral groove 20, corresponding two button bits are in contact fastening.More specifically
, around first connecting portion 11 1 weeks, spiral terrace 10 was more than one.And in the present embodiment, around first connecting portion 11 1 weeks, if
The spiral terrace 10 set is one, and the corresponding central angle of arc that spiral terrace 10 surrounds first connecting portion 11 is greater than 180 ° and small
In 360 °.
In this way, when driving gear 1 is rotated along the spiral salient direction of spiral terrace 10, spiral terrace 10 and spiral groove
20 fasten, and driving gear 1 drives the driven gear 2 to rotate synchronously.And in the driving gear 1 along the spiral of spiral terrace 10
When the opposite direction rotation of protrusion, the spiral terrace 10 is detached from the spiral groove 20, and the driving gear 1 cannot drive institute
The synchronous rotation of driven gear 2 is stated, the driven gear 2 does in the axial direction of first connecting portion 11 past along the track of spiral terrace 10
Multiple movement.Moreover, spiral terrace 10 and spiral groove 20 are respectively the one knot being arranged on driving gear 1 and driven gear 2
Structure can carry larger torque, realize that bearing capacity is transmitted in the big torque of clutch gear group.
For the clutch campaign that driven gear 2 Yu driving gear 1 is better achieved, referring to figure 1 and figure 2, in driven tooth
The side of the separate driving gear 1 of wheel 2 is provided with reset spring 3, and one end of reset spring 3 is connect with the driven gear 2, separately
One end is connected in first connecting portion 11, and reset spring 3 is in compressive state, for driving gear 1 along spiral terrace 10
When spiral salient direction rotates, precompression is provided for driven gear 2, fastens the spiral terrace 10 with the spiral groove 20
Securely；And when for driving gear 1 along the opposite direction rotation of the spiral salient of spiral terrace 10, pressure is provided for driven gear 2
Power guarantees that the driven gear 2 can move reciprocatingly in the axial direction of first connecting portion 11 along the track of spiral terrace 10.Pass through
The setting of reset spring 3 may make driving gear 1 and driven gear 2 in bonding state, spiral terrace 10 and spiral groove 20
Fastening it is secured, be not displaced, and driving gear 1 and driven gear 2 in the separated state, guarantee that driven gear 2 can edge
The track of spiral terrace 10 moves reciprocatingly in the axial direction of first connecting portion 11.
And specifically, the reset spring 3 is set in first connecting portion 11 in the present embodiment, and reset spring 3
One end is connected on driven gear 2, and the other end is abutted with the limited block 4 being fixed in first connecting portion 11.Further, this reality
It applies in example, the reset spring 3 is conical compression spring, and the vertex of a cone end of spring is abutted with limited block 4, and the cone bottom end of spring
It is abutted with driven gear 2.Wherein, the diameter of limited block 4 is greater than the cone top end diameter of conical compression spring and is less than driven gear 2
Diameter, so that the vertex of a cone end of conical compression spring is stablized and be connected on limited block 4；And the intermediate throughholes of driven gear 2 are hole
Two sections of different through-holes of diameter connect composition, and the diameter close to one section of through-hole of driving gear 1 is smaller, make the centre of driven gear 2
The stage with the direction Xiang Kongxin protrusion is formed inside through-hole, and the cone bottom diameter of conical compression spring is less than driven gear 2
Large through-hole diameter and be less than the diameter of small through hole, enable the cone bottom end of conical compression spring just accommodate be connected to it is raised
In stage, the abutting of reset spring 3 and driven gear 2 is realized.
In the present embodiment, referring to figs. 2 and 3 shown in a, one end end of the separate driving gear 1 of first connecting portion 11 has
There is limited block that bayonet 12 is installed；The limited block 4 is fixed on first connecting portion by setting with the limited block installation cooperation card of bayonet 12
On 11, the engaging by installing bayonet 12 with limited block is arranged, and fixes limited block 4 in the position of first connecting portion 11, thus
Guarantee reset spring 3 locating for space fix, thus guarantee reset spring 3 to the pressure of driven gear 2, and the engaging setting hold
It is quick detachable, it is easy for installation.
Above embodiments are only the preferred embodiment of the utility model, be only that the technical solution of the utility model make into
The detailed description of one step, but the protection scope of the utility model and embodiment are not limited, without departing from the spirit of the present invention
Change, combination, deletion, replacement or modification for being made under essence and principle etc. are included in the protection scope of the utility model
It is interior.
