Abstract
The invention discloses a screw drive planetary reducer which comprises a first threaded rod as an input shaft. The first threaded rod is meshed with multiple second threaded rods as planet gears. A sun gear is arranged outside each second threaded rod in a meshed mode. A planetary reducer cover is connected to the two sides of the first threaded rod and the two sides of the second threaded rods. The first threaded rod is connected to the center of the planetary reducer cover through a deep groove ball bearing. The second threaded rods are connected to the planetary reducer cover through deep groove ball bearings. The sun gears are connected to the outer edge of the planetary reducer cover through angular contact bearings. According to the screw drive planetary reducer, transmission is achieved through screw meshing rather than gear meshing, and the new design gets rid of a complete machine failure caused by a series of gear failures generated in traditional gear meshing.
Description
Technical field
The present invention relates to planetary reducer field, in particular to a kind of planetary reducer of power screw.
Background technique
Planetary reducer is a kind of broad-spectrum industrial products, and this retarder is applicable to the industrial fields such as lifting transportation, engineering machinery, metallurgy, mine, petrochemical industry, building machinery, industry light industry textile industry, medical apparatus, automobile, Aero-Space.
But on the market in common planetary reducer using process, most common failure has abnormal vibrations, serious heating, leakage of oil, abnormal sound and part failure etc. at present.Retarder Parts Breakdown mainly lost efficacy and caused, and statistics shows that gear failure proportion accounts for 60%, and bearing accounts for 19%, and both account for 80% of total failare quantity.Visible, gear failure is the main cause of decelerator trouble, the common wearing and tearing of failure mode geared surface (comprising eccentric wear), tired spot corrosion, gummed, plastic deformation, crackle and broken teeth etc.Common retarder installation precision deficiency causes in operation process, and gear bears due to mesh impact and wiring impact, produces abnormal vibration, and has noise.When heavy loading and over loading, constantly there are power friction and wearing and tearing in the flank of tooth, forms tired spot corrosion and peel off, and even produces large size butcher cuts, reduced the accuracy of mesh of gear, increased mesh impact, affects the retarder life-span when serious.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of planetary reducer of power screw is provided, break away from traditional gear engagement and machine failure that the series of gears that produces lost efficacy and causes.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of planetary reducer of power screw, comprise the first screw rod as input shaft, the first screw rod is engaged with a plurality of the second screw rods as planet wheel, and the second described screw rod outer gearing has sun gear, and described the first screw rod, the second screw rod both sides are connected with planetary reducer lid.
Further, described the first screw rod is connected to planetary reducer lid center by deep groove ball bearing.
Further, described the second screw rod is connected to planetary reducer by deep groove ball bearing and covers.
Further, described sun gear is connected to planetary reducer lid outer rim by angular contact bearing.
Preferably, described the second screw rod is provided with three, is uniformly distributed in around the first screw rod.
The invention has the beneficial effects as follows:
1, the present invention is by helical toothing but not gear meshes to reach transmission effect.The machine failure that the series of gears that this new design has produced with regard to having broken away from traditional gear engagement lost efficacy and causes.
2, flexible design can be any reduction speed ratio.
3, convenient processing and manufacture, cost is low.
4, the physical dimension that complete machine has is little, stable drive, and the life-span is long, and not easy to wear, precision easily guarantees.
5, compact structure, can be widely used in robot, can replace RV.
6, can transmit larger torque, than general planetary reducer transmission capacity, improve 20% left and right.
7, easy for installation, installation precision is high.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
