Description
Technical field
The utility model relates to a kind of plane table thermoconductivity meter, and particularly a kind of NGWN simply connected type plane table thermoconductivity meter belongs to the plane table thermoconductivity meter technical field.
Background technique
At present, in the structure of NGWN type plane table thermoconductivity meter, two planetary pinions that are installed on the planetary carrier structurally are the duplicate gear structures that adopts disjunctor, it is fixedly connected with being connected of planetary carrier that two planetary gear shafts are installed, planetary pinion by Bearing Installation on gear shaft.The mode of structure of the duplicate gear of this integral body, exist anufacturability relatively poor, the defective that machining accuracy is difficult to guarantee, in addition, because planetary pinion will be by Bearing Installation on planetary carrier, planetary center must have bigger hole so that bearing is installed, and this has just reduced planetary intensity to a certain extent, causes planetary damage easily.
The model utility content
The purpose of this utility model is: a kind of NGWN simply connected type plane table thermoconductivity meter is provided, overcomes existing above-mentioned defective in the existing NGWN type plane table thermoconductivity meter structure.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: a kind of NGWN simply connected type plane table thermoconductivity meter, it is by planetary carrier, mafor planet gear, gear shaft, bearing, back-up ring, small planetary gear, retainingf key is formed, plane table thermoconductivity meter has a mafor planet gear, the dowel hole of mafor planet gear and small planetary gear aligns, be placed on opening between the shelves of planetary carrier, retainingf key is placed in the keyway of gear shaft, gear shaft is passed the center hole of mafor planet gear and small planetary gear successively from the hole of planetary carrier one side, an end of gear shaft is arrived in the hole of the other side of planetary carrier; The outer ring of two bearings is installed in the hole of planetary carrier one side, and the inner ring of two bearings is connected with an end of gear shaft.
Beneficial effect: be easy to a bit because independent gear has manufacturing, so, adopt discrete planetary pinion to have manufacturability advantage preferably, can guarantee higher product quality, reduce manufacture cost, in addition, because planetary center hole has been cancelled the installation bearing, can reduce the size of center hole, correspondingly strengthen planetary intensity, planetary pinion is not fragile.
Description of drawings
Below in conjunction with accompanying drawing structure of the present utility model is described further;
Fig. 1 is a structure principle chart of the present utility model;
Shown in the figure: 1, planetary carrier; 2 mafor planet gears; 3, gear shaft; 4, bearing; 5, back-up ring; 6, small planetary gear; 7, retainingf key.
