Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of plane table thermoconductivity meter.
Background technique
The reducing gear that is used for electrically driven curtain at present, being generally multi-stage gear slows down, speed ratio is low, volume is big, cost is high, adopt general plane table thermoconductivity meter, though the space is little, speed ratio is big,, very easily damage because the output gear strength is excessive, if select the strong quality material of bearing capacity for use, then can increase cost and improve cost.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and cost is low, and noise is little and plane table thermoconductivity meter that strength is big.
For achieving the above object, the technical solution of the utility model is a kind of plane table thermoconductivity meter, comprise driving gear shaft, planet pinion and fixed annulus cover, planet pinion and driving gear shaft and fixed annulus cover tooth are in transmission connection, and its innovative point is:
An end is provided with internal tooth in the endoporus of a, fixed annulus cover, and the end of the other end is provided with bearing;
Be fitted with output shaft on the bearing that is provided with in the endoporus of b, described fixed annulus cover, output shaft one end stretches out outside the bearing, and the other end has movable internal gear, and internal gear is between the internal tooth and bearing of fixed annulus cover;
C, described planet pinion are duplicate gear, and wherein the internal tooth in Left-wing Federation's gear and driving gear shaft and the fixed annulus cover is in transmission connection, and the tooth in the movable internal gear of right connection gear and described output shaft the inner is in transmission connection.
Described planet pinion is four.
Be provided with intermediate gear in the middle of the right side connection gear of described four planet pinions.
Left-wing Federation's gear does not wait with the number of teeth of right connection gear in the described planet pinion.
It is described that to be installed in fixed annulus cover bearing at end be rolling bearing.
After adopting the technical solution of the utility model, owing to adopted output shaft with movable internal gear, and the space of movable internal gear is big, can increase the quantity of planet pinion, thereby increased the strength of gear, therefore the gear of common metal material can have been changed into the engineering plastics manufacturing, greatly reduced cost of production, reduce noise simultaneously, had good using effect.
