The setting of through hole 301, after gear 100 bears radial load, due to there is the presence of through hole 301, its can play compared with
Good cushioning effect, after larger radial load is born, the narrowed width of through hole 301, to aid in former 30 to produce small shape
Become, overall using effect is preferable.
Fig. 4 is refer to, optionally, gear 100 also includes the first detection piece 302 and the second detection piece 304, the first detection piece
302 one end is connected with former 30, and the other end of the first detection piece 302 is located in through hole 301, the first detection piece 302 it is another
End there is the first spherical test section 303, one end of the second detection piece 304 is connected with former 30, the second detection piece 304 it is another
In the through hole 301, the other end of the second detection piece 304 has the second spherical test section 305 at end, the first test section 303 with
Second test section 305 contacts.
First detection piece 302 and the second detection piece 304 can be being fixedly connected or be integrally formed with former 30
's.
Not in the case of by radial load, the first test section 303 contacts gear 100 with the second test section 305, works as gear
After 100 bear larger radial load, the narrowed width of through hole 301, then necessarily cause 302 relatively close second inspection of the first detection piece
Part 304 is surveyed, in the process, the first test section 303 and the second test section 305 produce friction, and friction necessarily leads to polishing scratch, uses
Person can intuitively find out whether the gear 100 once bore larger radial load by observing polishing scratch, so that former 30
Produced larger deformation.User can be according to the first test section 303 of gear 100 and the abrasion feelings of the second test section 305
Condition, it is determined whether need the gear 100 more renewed.
Embodiment 3
The present embodiment also provides a kind of transmission mechanism, and it includes gear 100 mentioned above, and it has the gear 100
Repertoire.
The structure of gear 100 may be referred to embodiment 1 or 2.
The transmission mechanism can select a gear 100 mentioned above, and two or more can also be selected above-mentioned
The gear 100 mentioned.
In the case that the transmission mechanism is in heavy duty, applying working condition is changeable, coupling gear engagement magnitude of misalignment is larger, have preferable
Using effect.
In summary, the invention provides a kind of gear 100, the gear 100 can deform under load effect, reduce each
Individual operating mode engagement magnitude of misalignment and magnitude of misalignment difference, reduce gear 100 and design profiling quantity, so as to ensure that the flank of tooth of gear 100 carries, carry
The high intensity of gear 100 and life-span.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
