Description

Rocket movable launcher awl tooth-double pendulum speed reducer
[technical field]
The present invention relates to the retarder technical field, a kind of rocket movable launcher awl tooth-double pendulum speed reducer.
[background technique]
The rocket movable launcher speed reducer must have reliability height, long service life, height lightweight etc.
Background technique has two kinds:
(1) osculating circle movable teeth reducer, subject matter is: maximum permission torque is little, and efficient is low, η≤70%;
(2) two inventions of Zhengzhou Research Institute of Mechanical Engineering " rocket movable launcher supporting arm speed reducer " (20091072401.4) and " rocket movable launcher reducer with small volume and large torque " (200910172402.9), subject matter is:
Awl tooth+third-level planetary slows down, and axial dimension is long, complex structure, and the lightweight degree is lower.
[summary of the invention]
That the object of the invention is to provide is a kind of " awl tooth+cycloid " double reduction, short, the lightweight height lightweight rocket movable launcher awl of axial dimension tooth-double pendulum speed reducer.
The advantage of the Gear Planet Transmission of cycloid velocity ratio is: (a) the single-stage reduction speed ratio is much bigger; (b) the cycloidal gear teeth flexural strength is high, never broken teeth; (c) manufacture cost is less than half of NGW planet.Shortcoming: the mechanical efficiency of cycloid transmission is lower than the NGW Gear Planet Transmission slightly, but for small-power, this is a minor issue.
Technological scheme of the present invention is as follows:
(A) technological scheme of carrying of raising cycloid and impact resistance:
(a) adopt the double cycloid structure, just replaced the pinwheel that constitutes by pin wheel housing, a lot of pin tooth and pin gear sleeve with the hypocycloid wheel.Thereby simple in structure, in addition part is few, the single-stage reduction speed ratio is very big, it is said to reach 200 (" the cycloid variable-speed motor that does not have pinwheel " mechanical transmission 2006.04); In addition, cycloidal gear teeth has very high counter-bending ability; (b) in the W output mechanism, all carry ring structure and make the cantilever pin become freely supported structure thereby adopt, improved the crooking ability of pin;
(B) technological scheme of single-stage big retarding ratio, multiple tooth engagement:
With in the silk thread cutting process processing hypocycloid gear ring of being careful, the single-stage reduction speed ratio is up to 200, and line cutting accuracy height, can make adjacent teeth apart from deviation≤0.005, tooth-face roughness is good, is equivalent to roll flute, thereby guarantees multiple tooth engagement.
[beneficial effect]
The present invention contrasts two inventions of Zhengzhou Research Institute of Mechanical Engineering, and its novelty, creativeness and practicability are embodied in:
(a) double reduction, axial dimension is short, in light weight, the height lightweight;
(b) internal cycloidal gear and external tooth cycloid wheel are the pure rolling engagement, and therefore under the input power same case, the retarder volume can reduce by 1 grade, thereby has the Gear Planet Transmission bearing capacity of four planet wheels big than only;
(c) the cycloidal reducer price is less than half of planetary reducer, thereby cost can hang down 40-55%.
[description of drawings]
