[embodiment]

About aforementioned and other technology contents, characteristics and effect of the present utility model, in the following detailed description that cooperates with reference to graphic preferred embodiment, can clearly present.

Consult Fig. 4, the preferred embodiment of the elimination back of tooth gap device that the utility model tool is glossy, comprising one supplies a rotating shaft 201 to wear and mesh first follower 3 of a driving gear 202, one this rotating shaft 201 of confession wears and is placed in this first follower 3 and meshes second follower 4 of this driving gear 202, one can detain the clasp 5 that is formed on this first follower 3, several are arranged on the pressure spring 6 on this first follower 3 and second follower 4, an and fixed plate 7 that rests on this second follower 4, as shown in Figure 5, this clasp 5 is after the system of buckleing on this first follower 3 is fixing, can this fixed plate 7 of packing, make this fixed plate 7 abut against this second follower 4, and can avoid described pressure spring 6 to come off, and the elimination back of tooth gap device of present embodiment is in order to be installed in the engine casing, certainly also can be installed in other the transmission device, not as limit.

Consult Fig. 4,5, this first follower 3 has an axial region 30, one is formed in this axial region 30 and the axis hole 301 that can supply this rotating shaft 201 to wear, one from the outward extending fluted disc 32 of these axial region 30 peripheries, and one protrude out and can be for the sheathed flanged housing 31 of this second follower 4 from these axial region 30 ora terminalis, at least one is formed at the side face 311 of this flanged housing 31 and extends axially and can import the groove portion 33 of an oil plant, and one around side face 311 that is formed at this flanged housing 31 and the positioning ring groove 34 that is communicated with described groove portion 33, in the present embodiment, be that the side face 311 that discloses this flanged housing 31 is formed with three groove portions 33, and described groove portion 33 is to be equidistant setting.

Consult Fig. 5,6, the structure of this clasp 5 generally is the C type and the system of can buckleing is fixed in this positioning ring groove 34, and be formed with an inner ring surface 52 in inner circumference edge, wherein, each groove portion 33 is separated to form a Lead-In Area 332 by this clasp 5, an and reserve 331, and the inner ring surface 52 of this clasp 5 is that the root edge 334 with each groove portion 33 is formed with a spacing 333, this Lead-In Area 332 is to be connected by this spacing 333 with reserve 331, this reserve 331 is to be positioned at this clasp 5, the inner ring surface 71 of fixed plate 7, between the inner ring surface 41 and flanged housing 31 of second follower 4, and this reserve 331 can lay in oil plant, reaches glossy effect with the inner ring surface 41 to second follower 4.

According to above-mentioned structure, when as shown in Figure 3 rotating shaft 201 drives this first follower 3 and rotates, first follower 3 that can be rotated owing to described pressure spring 6 is pushed and is produced elastic restoring force, second follower 4 on the axial region 30 that is set in this first follower 3 is pushed against by described pressure spring 6, and this second follower 4 is reversed towards the direction displacement of rotating in contrast to this first follower 3, and then dwindle this first, two

followers

3,4 and this driving gear 202 between the gear clearance distance, eliminate whereby this driving gear 202 with this first, two followers 3, back of tooth crack between 4, and can effectively reduce the noise that the gear engagement collision is produced.

What deserves to be mentioned is, when this rotating shaft 201 during at idle running, the rotational velocity of this first follower 3 is slower, the oil plant of this engine casing (figure do not show) can splash on this first follower 3 and accumulate in the described groove portion 33, again because the inner ring surface 52 of this clasp 5 and the root edge 334 of each groove portion 33 are formed with a spacing 333, make this oil plant can flow to this reserve 331, be infiltrated in the oil plant of this reserve 331 so as to inner ring surface 41 parts that make this second follower 4 via the Lead-In Area 332 of described groove portion 33.

When these rotating shaft 201 rotating speeds are higher than the speed of idle running, the speed that this first follower 3 rotates accelerates and produces bigger centrifugal force, the oil plant court of the reserve 331 of described groove portion 33 is radially thrown away, at this moment, because this clasp 5 covers block between this reserve 331 and Lead-In Area 332, make oil plant in the described reserve 331 be restricted to and wherein be unlikely to outflow, and then make this oil plant along the inner ring surface 41 of this second follower 4 and the Gap Flow between the flanged housing 31, and the inner ring surface 41 of this second follower 4 is subjected to the glossy of this oil plant and forms a lubricant film, utilize this lubricant film to separate the inner ring surface 41 of this second follower 4 and the flanged housing 31 of first follower 3, can avoid both to contact friction and reduction abrasion.

By above-mentioned design, the glossy elimination back of tooth gap device of the utility model tool is eliminated back of tooth gap device compared to having now, has the following advantages really:

1. produce glossy effect

Be formed with at least one groove portion 33 by side face 311 at this flanged housing 31, make this first and

second follower

3,4 when rotation, this oil plant can flow in this groove portion 33 and soak into the inner ring surface 41 of this second follower 4, and then the inner ring surface 41 that makes this second follower 4 coated these oil plant films and can be avoided directly contact with this first follower 3 friction, can reduce so as to making effect that these second follower, 4 generations lubricate and this first follower 3 between abrasion.

2. obtain more uniform lubricant film

In this enforcement, described groove portion 33 is several and is equidistant setting, make this oil plant can flow into the inner ring surface 41 of this second follower 4 equidistantly, and then make this oil plant be uniformly distributed in the inner ring surface 41 of this second follower 4, and the abrasion that more can alleviate this second follower 4.

3. help importing oil plant

When this rotating shaft 201 during at idle running, by the design of described groove portion 33, the oil plant of this engine casing (figure does not show) is splashed on this first follower 3, help the Lead-In Area 332 of this oil plant from described groove portion 33 flowed in the reserves 331.

4. can accumulate oil plant and not deficient

The reserve 331 that utilizes each groove portion 33 is between the inner ring surface 41 and flanged housing 31 of inner ring surface 71, second follower 4 at this clasp 5, fixed plate 7, when these rotating shaft 201 rotating speeds are higher than the speed of idle running, the centrifugal force that this first follower 3 is produced can make the oil plant of described groove portion 33 towards radially throwing away, but because this clasp 5 is to cover this reserve 331 of block, make oil plant in the described oil storage 331 be restricted to and wherein be unlikely to outflow, thereby described reserve 331 can be accumulated quantitative oil plant is arranged and not deficient.

In sum, be formed with several groove portions 33 by side face 311 at the flanged housing 31 of this first follower 3, and can when these rotating shaft 201 idle runnings, this oil plant be directed in the reserve 331 of described groove portion 33, be formed with the oil plant film between this first and

second follower

3,4 and have lubricated effect so as to making, and then reduce abrasion between this first follower 3 and second follower 4, so can reach the purpose of this utility model really.

The above, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, promptly the simple equivalent of doing according to the utility model claim and novel description generally changes and modifies, and all still belongs in the scope that the utility model patent contains.
