Abstract
The utility model relates to a mechanism of planetary gear meshing reliability improves is particularly useful for the obvious and serious condition of planet teeth directional unbalance loading of the uneven condition of carrying between the planet wheel. This mechanism includes clamp plate, locating pin, planet revolving rack curb plate, bush, planet round pin axle, planet wheel, snap ring and wear -resisting fender ring, and its relation of connection is: A, ) for curb plate bolted connection of clamp plate and planet revolving rack, B, ) the bush passes through the locating pin connection with planet revolving rack curb plate, C, ) form the ring that floats between planet round pin axle and the bush, D, ) the planet wheel passes through the crowned tooth machanism hookup with planet round pin axle, E, ) the planet wheel is through snap ring axial positioning. Uneven carrying is floated the ring by round pin axle department and is adjusted between this bank's star gear, when the load distribution is unbalanced when between the planet wheel, but floats and encircles the autoregulation deflection, plays all effects of carrying. The planet wheel joins with the cydariform tooth of round pin betweencenters, and when the planetary gear meshing unbalance loading was serious, there was the swing degree of freedom in the planet wheel, can effectively improve teeth of a cogwheel teeth directional load distribution characteristic.
Description
Technical field
This utility model relates to a kind of mechanism improving planetary gear engagement reliability, is particularly suited between planetary gear
The uneven situation that load situation is more apparent and planet teeth directional unbalance loading is serious.
Background technology
At present, domestic load balancing mechanism of planetary reducer is mostly to use a certain component that floats to realize all carrying, and it is equal
Carrying DeGrain so that reductor power density ratio is low, material, manufacturing cost are expensive.For planetary gear
Being the situation of load distribution along width inequality, current common method is gear teeth axial modification.But for load fluctuation
Bigger industrial gear-box, axial modification cannot make planet circular system keep more satisfactory under many, varying load
Load distribution along width.At this moment develop a kind of new reliability improvement planet high, low cost of manufacture to engage
The mechanism of reliability is the most necessary.
Utility model content
The technical problems to be solved in the utility model is: for the uneven load situation between planet circular system and gear
The situation that load distribution along width is uneven, proposes a kind of mechanism improving planetary gear engagement reliability.
This utility model is that the technical scheme solving the proposition of above-mentioned technical problem is: one improves planetary gear engagement
The mechanism of reliability, including pressing plate, alignment pin, planet pivoted frame side plate, lining, planet bearing pin, planetary gear,
Snap ring and wear-resisting baffle ring, its annexation is:
A) pressing plate and planet pivoted frame side plate bolted on connection, limits lining axial freedom；
B) lining is connect by alignment pin with planet pivoted frame side plate, and wherein said alignment pin is junction of the edges of two sheets of paper pin, specifically
Structure is that dowel hole axis is at lining with pivoted frame side plate faying face；Play location and transmission moment of torsion effect；
C) floating ring is formed between planet bearing pin and lining；
D) planetary gear is coupled by crowned tooth machanism with planet bearing pin；
E) planetary gear is axially positioned by snap ring, and described snap ring is installed on planetary gear endoporus, the spacing of two snap rings
From compared with the planet bearing pin big 0.3-0.5mm of the barreled tooth flank facewidth.
Preferably, described crowned tooth machanism connection can be spline or other have local swing degree of freedom biography
Turn round mechanism.
Preferably, described floating ring is bush(ing) bearing.
Preferably, described wear-resisting baffle ring can be thrust bearing shoe valve device or high-abrasive material ring, described wear-resisting baffle ring with
Lining is structure as a whole design, i.e. bush end face increases seam, and seam end processes through special process.
Preferably, described planetary gear can vertical or horizontal layout.
Beneficial effect:
Between planetary gear, uneven load is regulated by bearing pin floating ring, when when between planetary gear, load distribution is unbalanced, floating
But rotating ring self regulation deflection, plays all load effects.Barreled tooth flank connection between planetary gear and bearing pin, works as row
When star-wheel engagement unbalance loading is serious, there is swing degree of freedom in planetary gear, can be effectively improved gear teeth load distribution along width
Characteristic.
In low-speed heave-load Planetary Gear Transmission, use floating ring can be effectively improved between planetary gear uneven load characteristic,
And compared with rolling bearing, cost is relatively low.And floating ring suppression vibrating effect is good, impact resistance, it is beneficial to
Reductor even running.Crowned tooth machanism bind mode between planetary gear and bearing pin, planetary gear can be at certain model
Enclose swing, can effectively regulate the engagement skewness produced due to component processing, deformation.Planetary gear can be met exist
All there is good load distribution along width under many, varying load, be effectively increased the reliability of planet circular system.
