The cycloid speed-reducing device has the advantages of two-stage speed reduction, short axial size, light weight and high quantization; in addition, as cycloid gear teeth and semi-buried teeth are continuous, the cycloid speed-reducing device has larger bearing capacity than that of a planetary transmission with only four planet gears; moreover, the cost of the cycloid speed-reducing device is lowered by 40%-55%.
Description
[technical field]
The present invention relates to the retarder technical field, a kind of cycloid speed-reducing device of rocket launching movable platform.
[background technique]
The rocket movable launcher speed reducer must have that reliability is high, a 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:
Cone tooth+third-level planetary slowing-down structure, axial dimension is long, complex structure, the lightweight degree is lower.
[summary of the invention]
That the object of the invention is to provide is a kind of " cone tooth+cycloid " double reduction, the light-weighted cycloid speed-reducing device of rocket launching movable platform of short, the lightweight height of axial dimension.
The gear-driven advantage of the planet of cycloid velocity ratio is: (a) single-stage speed reducing is than 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 slightly is lower than the NGW Gear Planet Transmission, but for small-power, this is minor issue.
Technological scheme of the present invention is as follows:
(A) technological scheme of the carrying of raising cycloid and impact resistance:
(a) toothing is partly buried in employing, makes gear pin have very high counter-bending ability;
(b) in the W output mechanism, make the cantilever pin become freely supported structure with all carrying ring, improved the crooking ability of pin;
(B) technological scheme of realization single-stage big retarding ratio, multiple tooth engagement:
With middle slow wire feeding wire cutting technology machined needles alligator hole, the single-stage speed reducing ratio is up to 150-180 (more the big retarding ratio is larger for type), and the line cutting makes adjacent holes apart from deviation≤0.005-0.01, 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, lightweight, the height lightweight;
(b) cycloidal gear teeth reaches and partly buries not broken teeth of tooth, thereby has the Gear Planet Transmission bearing capacity of four planet wheels large than only;
(c) the cycloidal reducer price less than planet half, thereby the low 40-55% of cost.
