Description
Technical field
The utility model relates to a kind of transmission mechanism, specifically a kind of low-noise, high efficiency, long-life planetary gear
Mechanism.
Background technique
In reduction gearbox industry, planetary gear transmission mechanism is very widely used, but existing speed reduction gear box is exhausted
Most of is all that the material of gear itself is assembled with it, therefore many gear rotations is caused to be the sliding friction in face and face, mill
Damage is big, and low efficiency, service life end, noise are big.Further, since the machining accuracy of practical materials and parts is limited, answered in specific product
Used time often causes center gear wheel that can cause biggish abrasion in side due to some gear because of abrasion deviation, exists in this way
Long interim meeting cause a series of problems because of gear wear.
Summary of the invention
The purpose of this utility model is to provide a kind of low-noise, high efficiency, long-life planetary gear mechanism, the machines
Structure can reduce magnet-wheel rotation bring abrasion.
The technical scheme adopted by the utility model is that：A kind of low-noise, high efficiency, long-life planetary gear mechanism,
Including sun gear, planetary gear, planet plate and outer gear ring, the periphery of the sun gear is provided with several planetary gears and too
Sun wheel is intermeshed with each planetary gear, and the planetary gear setting is expert on starboard, is equipped with institute in planetary gear periphery
Outer gear ring is stated, the inside gear ring and each planetary gear of outer gear ring are intermeshed, it is characterised in that the sun gear is fixedly mounted
It is expert at the center of starboard, and starboard surrounding of being expert at is fixedly installed with planet plate straight pin, planet plate straight pin is set around sun gear
It sets, needle bearing is installed in the planetary gear inner ring, the needle bearing is sleeved on planet plate straight pin, needle roller axis
The outer wall held is fixedly connected with planetary gear inner ring, is contacted between the inside needle roller of needle bearing and the planet plate straight pin
Formula connection, needle bearing are rotated by the rolling of internal needle roller around planet plate straight pin.
The sun gear, planetary gear and planet plate straight pin are an integral structure.
The planetary gear quantity is three, and is separately positioned on around sun gear and is meshed with sun gear.
The utility model has the beneficial effects that：This planetary gear mechanism is by by the internal gear of existing reduction gearbox motor
Structure improves, and is bumped into needle bearing in inner hole of planetary gear, makes between planetary gear and straight pin by original face and face
Sliding friction is changed to rolling friction, substantially reduces abrasion；Clearance is also added simultaneously, reduces element precision requirement；Guarantee
Product long-life, low noise and improve rotational efficienty.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.

3 outer wall is fixedly connected with the inner ring of planetary gear 2, and the inside needle roller of needle bearing 3 and the planet plate straight pin 6 are indirectly
Touch connection, needle bearing 3 are rotated by the rolling of internal needle roller around planet plate straight pin 6.
The sun gear 1, planetary gear 2 and planet plate straight pin are an integral structure.
The quantity of the planetary gear 2 is three, and is separately positioned on around sun gear 1 and is meshed with sun gear 1.
The matching relationship of this planetary gear mechanism is：Outer gear ring 5 is fixed, and 1 active of sun gear and planet plate 4 actively, drive
Passive planet tooth 4 carrys out back rotation.
The basic principles and main features and advantage of the utility model have been shown and described above.The ordinary skill of this field
Personnel are not it should be appreciated that above-described embodiment limits the protection scope of the utility model, all use equivalent replacements etc. in any form
Mode technical solution obtained, falls in the protection scope of the utility model.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
