Abstract
The utility model relates to a planet gear train comprising a uniform-loading device. The planet gear train comprising the uniform-loading device comprises a planet carrier, a planet gear, a planet pin shaft, bearings, an inner gear ring and a sun gear and is characterized in that the middle of the planet pin shaft is a bearing mounting shaft neck, and the two ends of the planet pin shaft are supporting mounting frustums; the tops of the supporting mounting frustums are the end faces of the planet pin shaft, and the two ends of the planet pin shaft are mounted on the planet carrier through tapered uniform-loading sleeves matched with the supporting mounting frustums; pressing plates preventing the uniform-loading sleeves from moving are arranged at the two ends of the planet pin shaft, and the pressing plates are fixedly mounted on the planet carrier.
Description
Technical field
The utility model relates to a kind of planetary gear train, especially a kind of planetary gear train that contains load-balancing device.
Background technique
Planetary speed reducer system great majority are to adopt dual-sided board planet pivoted frame at present, this planet pivoted frame inevitably can produce distortion after stressed, especially the biside plate distortion is inconsistent, and this just causes planetary pinion to cause the generation of engagement inequality and unbalance loading phenomenon when engagement.Traditional planet bearing pin is directly to be installed on the planet carrier in the planet axis hole on the biside plate, also produces the uneven phenomenon of carrying when machining error and assembly error make the planet wheel engagement owing to make.How to make planet wheel when transmission, not produce unbalance loading, realize that load evenly also improves the reliability of all carrying between planet wheel, become the focus that people pay close attention to.
The model utility content
The purpose of this utility model is: at directly being installed on load inequality and unbalance loading phenomenon between the planet wheel that causes in the planet carrier owing to the planet bearing pin in the present planetary gear train, provide a kind of novel planetary gear train that contains load-balancing device.
The purpose of this utility model is achieved in that a kind of planetary gear train that contains load-balancing device, comprise planet carrier, planet wheel, planet bearing pin, bearing, ring gear, sun gear, it is characterized in that: for bearing axle journal is installed in the middle of the planet bearing pin, frustum is installed for supporting in two ends, supporting the top that frustum is installed is the end face of planet bearing pin, planet bearing pin two ends are by being installed on the planet carrier with the cover that all carries that supports the band tapering that the frustum coupling is installed, the two ends of planet bearing pin are provided with prevention and all carry the mobile pressing plate of cover, and pressing plate is fixedly mounted on the planet carrier.
In the utility model: described planet carrier is the dual-sided board planet carrier, and it is annular pressing plate that the mobile pressing plate of cover is all carried in prevention; Planet bearing pin one end supports the cone bottom diameter that frustum is installed and greater than bearing axle journal is installed, the other end supports the cone bottom diameter that frustum is installed and less than bearing axle journal is installed, the side that rear bearing is installed is closely against the big support of diameter and installs at the bottom of the awl of frustum, is provided with distance ring between the opposite side of bearing and the side plate of planet carrier.
In the utility model: the tapering that planet bearing pin two end supports is installed frustum is 1o-2.1o.
In the utility model: described bearing is selfaligning roller bearing, or cone axis, perhaps the full roller bearing of biserial.
In the utility model: comprise three in the epicyclic train at least and be evenly distributed on corresponding sun gear planet wheel on every side.。
Advantage of the present utility model is: when the planet pivoted frame is inconsistent owing to stressed generation biside plate is out of shape, since adopted tapering arranged all carry cover, produce distortion when stressed when all carrying cover, the stressed distortion that produces when big is just big, this distortion can remedy the inconsistency of planet pivoted frame biside plate distortion, make the planet wheel axis keep not deflection, realize all carrying of planet wheel engagement.
