Here, explanation forms the material of outer barrel 2 and wobble gear 14,16.
Outer barrel 2 is formed by the linear expansion coefficient material bigger than the material of the first wobble gear 14 and the second wobble gear 16.
Specifically, outer barrel 2 is aluminium alloy system, and the linear expansion coefficient for forming the material of outer barrel 2 is 20.0~23.5 μ/K.In contrast,
Wobble gear 14,16 is formed by ferrous material.Such as wobble gear 14,16 can also be made up of carbon content of 0.7~1.0% steel
(high-carbon steel), or be made up (low-carbon steel) of the steel that carbon content is less than 0.2%.Now, wobble gear 14,16 is formed
The linear expansion coefficient system of material is 10.8~11.0 μ/K, or 11.6~11.7 μ/K.Moreover, these ferrous materials are quenched
Fire and make these ferrous materials harden after, its carbon content be less than 0.2% in the case of, its linear expansion coefficient turn into 13.6 μ/
K, in addition, in the case where its carbon content is 0.7~1.0%, its linear expansion coefficient turns into 12.0~12.5 μ/K.In addition, on
Interior alligator 3, also by being formed with wobble gear 14,16 identical materials.
It is as described above, in the geared system 1 of present embodiment, form the line expansion of the material of wobble gear 14,16
Coefficient is less than the linear expansion coefficient for the material for forming outer barrel 2.Therefore, outer barrel 2, bearing 4 and swing when using geared system 1
When gear 14,16 heats up, the expansion ratio wobble gear 14,16 of outer barrel 2 is big.Therefore, the interior alligator 3 of outer barrel 2 and wobble gear 14,
Gap between gap between 16 external tooth 14a, 16a, the i.e. inner peripheral surface of outer barrel 2 and wobble gear 14,16 will not be than using
Preceding state is also narrow.Therefore, even if wobble gear 14,16 heats up and expanded, the flank of tooth of wobble gear 14,16 can also be suppressed
Face pressure uprise, the service life that can suppress wobble gear 14,16 shortens.
In addition, in the present embodiment, outer barrel 2 is aluminium alloy system, wobble gear 14,16 is formed by ferrous material, therefore,
It can make to form the difference of the linear expansion coefficient of material of the linear expansion coefficient of the material of outer barrel 2 with forming wobble gear 14,16 greatly.
Therefore, become even in the temperature of wobble gear 14,16 and the temperature difference of the temperature of outer barrel 2 under big use environment, can also press down
The face pressure of the flank of tooth of wobble gear 14,16 processed uprises.Accordingly, the service life that can be more reliably suppressed wobble gear 14,16 becomes
It is short.
In addition, the invention is not limited in the embodiment, various changes can be carried out in the range of its purport is not departed from
More with improvement etc..Such as in said embodiment, the structure provided with two wobble gears 14,16 is employed, but it is of the invention
It is not limited to this.Can also exemplified by such as with a wobble gear structure, or the knot provided with more than three wobble gears
Structure.
In said embodiment, the central portion that input shaft 8 is arranged at bearing 4 is employed, and multiple bent axles 10 are arranged at
Structure around input shaft 8, but it is not limited to this.A such as bent axle 10 can also be used to be arranged at the center of bearing 4
The centre-crank formula structure in portion.Now, as long as being arranged to input shaft 8 is engaged in the travelling gear 20 for being installed in bent axle 10, then
It may be disposed at any position.
In said embodiment, exemplified with the situation that outer barrel 2 is aluminium alloy, but outer barrel 2 is not limited to aluminium conjunction
Gold system.Such as can also be that outer barrel 2 and wobble gear 14,16 are formed by ferrous material.But now, outer barrel 2 needs swollen by line
The material that the material of swollen coefficient ratio wobble gear 14,16 is big is formed.If for example, outer barrel 2 by carbon content be less than 0.2% steel
(low-carbon steel) is made and is quenched hardening, then linear expansion coefficient is 13.6 μ/K.Now, wobble gear 14,16 can be by carbon content
It is made (high-carbon steel) for less than 0.7~1.0% steel.In the case, make to form the quenching of the material of wobble gear 14,16 firmly
Linear expansion coefficient after change is 12.3~12.4 μ/K.Now, interior alligator 3 also can by with wobble gear 14,16 identical material shapes
Into.
Here, summarize the embodiment.
(1) in said embodiment, material of the linear expansion coefficient of the material of wobble gear than forming first portion is formed
The linear expansion coefficient of material is small.Therefore, first portion, second portion and wobble gear liter when using Eccentrically swinging gear device
Temperature, the expansion in first portion are more than the expansion of wobble gear.Therefore, between the internal tooth in first portion and the teeth portion of wobble gear
Gap, i.e., the gap between the inner peripheral surface and wobble gear in first portion will not be narrower than the state before use.Therefore, even in pendulum
Moving gear heats up in the case of expansion, and the face pressure that can also suppress the flank of tooth of wobble gear uprises, and can suppress wobble gear
Service life shorten.
(2) first portion is alternatively aluminium alloy system, and the wobble gear can also be formed by ferrous material.
In the structure shown here, can make to form material of the linear expansion coefficient of the material in first portion with forming wobble gear
The difference of linear expansion coefficient is big.Therefore, big use is become even in the temperature of wobble gear and the temperature difference of the temperature in first portion
Under environment, the face pressure that can also suppress the flank of tooth of wobble gear uprises, and accordingly, can more be reliably suppressed wobble gear uses the longevity
Life shortens.
(3) first portion can also be formed by the ferrous material that carbon content is less than 0.2%, the wobble gear
It can be formed by the ferrous material that carbon content is 0.7~1.0%.
As described above, according to the embodiment, the face pressure that can suppress the flank of tooth of wobble gear uprises, accordingly, it is capable to
The service life for enough suppressing wobble gear shortens.
