The rotating speed of frictional resistance between planet tooth and gear ring, planetary reduction gear entirety is greatly improved, and retardation efficiency carries therewith
Rise, and noise when retarder operation is small, the abrasion after in addition frictional resistance becomes smaller between planetary gear and gear ring also with
Become smaller, the service life of planetary reduction gear is more permanent.4, by the way that gasket is arranged between adjacent two-stage planet group,
The friction between planetary gear and pinion frame is reduced, keeps the mass motion of planetary reduction gear more smooth, operation noise subtracts
Small, service life extends.
Description of the drawings
Fig. 1 is the cross-sectional view of the present invention;
Fig. 2 is the enlarged structure schematic diagram of part A in Fig. 1.
Specific implementation mode
Below in conjunction with attached drawing, invention is further explained：
As depicted in figs. 1 and 2, the present embodiment provides a kind of Novel planetary gear reducer, including gear ring 1, upper flange 2,
Lower flange 3 and planetary gear set 4, upper flange 2 and lower flange divide 3 both ends that Gai be located at gear ring 1, the planetary gear set 4 to set
It sets in gear ring 1, gear ring 1 is equipped with input terminal and output end, has inclined-plane 11 at the inner ring of the input terminal, the inclined-plane 11 is certainly
Gear ring inner peripheral surface extends toward at the tooth top of its internal tooth；The planetary gear set 4 includes pinion frame 41 and planet tooth 42, described
Pinion frame 41 is located in gear ring 1, and planet tooth 41 is sequentially connected by axis pin and pinion frame 41, with ring gear 1
Engagement area gradually increases outside in.
Make inclined-plane processing in the input terminal of gear ring 1, be in order to reduce the engagement area between planetary gear set 4 and gear ring 1,
Since engagement area is reduced, the frictional resistance between planetary gear and gear ring in first order planetary gear set it is opposite in the past greatly
Big to reduce, since resistance reduces, the input speed of first order planetary gear set can be improved, in addition in planetary portion
Point, it being adjusted on planet tooth-formation of gear, the sectional area of tooth form is tapered into from one end close to gear ring toward axis direction,
In planet gearset motions, since planetary gear is first contacted with gear ring close to one end of gear ring, due to close to gear ring one end
Tooth sectional area is smaller, and when planetary gear setting in motion just touches gear ring, and resistance can be relatively small, with planetary
Rolling resistance slowly increases；Pass through this principle so that planetary gear relative smooth, rotating speed when rolling are improved.
The upper flange 2 is fixed by screws with gear ring 1, and the upper end of the lower flange 3 is equipped with internal thread 31, gear ring
1 lower end is equipped with the external screw thread coordinated with lower flange 3, and lower flange 3 and gear ring 1 are threadedly coupled；By way of screw-thread fit, make
The concentricity for obtaining retarder entirety is more preferable, and relative to the mode of lock screw, assembling is more efficient and convenient, when being tested
Directly lower flange is unscrewed, is installed with corresponding testing of electric motors screw-thread fit.
Catch 5 is equipped between the planetary gear set 4 and lower flange 3, being equipped with for the catch 5 is opposite with planet carrier axle center
The through-hole 51 answered, the diameter of catch 5 are less than the diameter of lower flange 3；Catch 5 can prevent lubricating grease to be lost in, at catch
For through-hole in order to corresponding with the axle center of planet carrier, it is eccentric orfice to change through-hole, is not shaken just catch can be fixed in gear ring.
The internal tooth of the gear ring 1 is corresponded to is equipped with the inclined-plane per the engagement place of the planet tooth 42 of level-one planetary gear set 4
11；By the way that corresponding with each group of planetary gear set 4 inclined-plane 11 is arranged in gear ring, can further decrease planet tooth 42 and
The rotating speed of frictional resistance between gear ring 1, planetary reduction gear entirety is greatly improved, and retardation efficiency is promoted therewith, and
Noise when retarder operation is small, and the abrasion after in addition frictional resistance becomes smaller between the wheel of planet tooth 42 and gear ring 1 also becomes therewith
Small, the service life of planetary reduction gear is more permanent.
Gasket is additionally provided between adjacent two-stage planet group 4, the gasket 6 is sheathed on the sun of pinion frame 41
It is contacted on wheel and with 42 face of planet tooth of next stage planetary gear set 4；By being arranged between adjacent two-stage planet group 4
Gasket 6 reduces the friction between planetary gear 42 and pinion frame 41, keeps the mass motion of planetary reduction gear more smooth,
It runs noise to reduce, service life extends.
