First snap-gauge is arc-shaped, and first snap-gauge both ends are fixedly connected to the first connecting plate, and screw thread connects on first connecting plate
It is connected to bolt, the bolt thread runs through the first connecting plate and the second connecting plate, and is fastened by nut.
Preferably, the position-limit mechanism includes being provided with shaft two sides limiting slot, is fixedly connected on the cylinder inner wall
Limited block, the limited block are slidably arranged in limiting slot.
Preferably, the gear outer ring is engaged with multiple planetary gears.
Preferably, shoe cream room is offered on the gear, the shoe cream room is provided with and communicated with through-hole.
Preferably, the nut is hex nut.
The utility model proposes a kind of modified sun gear, beneficial effect is: position-limit mechanism, the first snap-gauge, second
The design of snap-gauge, bolt, nut, convenient for cylinder to be fixed in shaft, good fixing effect will not make cylinder that phase occur with shaft
It to displacement, is also convenient for that cylinder is installed when logical, the design of shoe cream room and through-hole plays the role of lubrication, is conducive to the sun
Transmission between wheel and planetary gear.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of modified sun gear structural schematic diagram；
Fig. 2 be the utility model proposes a kind of modified sun gear top view.
In figure: the first connecting plate 1, bolt 2, gear 3, card slot 4, cylinder 5, the first snap-gauge 6, limited block 7, the second connecting plate
8, nut 9, limiting slot 10, shaft 11, the second snap-gauge 12, shoe cream room 13, through-hole 14.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of modified sun gear, including cylinder 5, are fixedly connected with gear 3 on the outside of cylinder 5, outside gear 3
Circle is engaged with multiple planetary gears, shoe cream room 13 is offered on gear 3, shoe cream room 13 is provided with and communicated with through-hole 14, in shoe cream room
Lubricating oil is packed into 13, when cylinder 5 is rotated, lubricating oil can be leaked out from through-hole 14, be applied to gear 3 and planetary gear
Between play the effect of lubrication, prevent corrosion, the stuck situation of assembly.
5 inner ring of cylinder is plugged with shaft 11, and the diameter of shaft 11 matches with 5 internal diameter of cylinder, shaft 11 and cylinder 5 it
Between be equipped with position-limit mechanism, position-limit mechanism include be provided with 11 two sides limiting slot 10 of shaft, be fixedly connected with limit on 5 inner wall of cylinder
Block 7, limited block 7 are slidably arranged in limiting slot 10, are being rotated by shaft 11, due to 10 phase of limited block 7 and limiting slot
Cooperation will drive cylinder 5 to rotate, and instead of traditional welding, can prevent from that opposite position occurs between shaft 11 and cylinder 5
It moves, while being also convenient for for cylinder 5 being mounted in shaft 11.
5 both ends of cylinder are fixedly connected to the second snap-gauge 12, and the second snap-gauge 12 is arc-shaped, and the second snap-gauge 12 and shaft
11 abut against, and the both ends of the second snap-gauge 12 are fixedly connected to the second connecting plate 8, and shaft 11 offers card slot 4, puts in card slot 4
It is equipped with the first snap-gauge 6, and the first snap-gauge 6 is arc-shaped, 6 both ends of the first snap-gauge are fixedly connected to the first connecting plate 1, the first connection
Bolt 2 is threaded on plate 1,2 screw thread of bolt runs through the first connecting plate 1 and the second connecting plate 8, and carries out tightly by nut 9
