Abstract
The utility model discloses a screw drive planet reducer. The screw drive planet reducer comprises a first screw serving as an input shaft. The first screw is meshed with a plurality of second screws serving as planet wheels. The second screws are externally meshed with a sun wheel. The two sides of the first screw and the two sides of each second screw are connected with a planet reducer cover. The first screw is connected to the center of the planet reducer cover through a deep groove ball bearing. The second screws are connected to the planet reducer cover through deep groove ball bearings. The sun wheel is connected to the outer edge of the planet reducer cover through an annular contact bearing. According to the screw drive planet reducer, the drive effect is achieved through screw meshing rather than gear meshing. By means of the new design, the complete machine fault caused by a series of gear failures generated in traditional gear meshing can be avoided.
Description
Technical field
The utility model 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 transport, 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.In the time of 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.
Model utility content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of planetary reducer of power screw is provided, and breaks away from traditional gear engagement and the series of gears that the produces machine failure causing that lost efficacy.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model 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 multiple 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 beneficial effects of the utility model are:
1, the utility model is by helical toothing but not gear engages to reach transmission effect.This new design has just been broken away from traditional gear engagement and the series of gears that the produces machine failure causing that lost efficacy.
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 ensures.
5, compact structure, can be widely used in robot, can replace RV.
6, can transmit larger torque, improve 20% left and right than general planetary reducer transmission capacity.
7, easy for installation, installation precision is high.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1, Fig. 2, a kind of planetary reducer of power screw, comprise the first screw rod 1 as input shaft, the first screw rod 1 is engaged with three the second screw rods 2 as planet wheel, the second screw rod 2 is uniformly distributed in around the first screw rod 1, the second described screw rod 2 outer gearings have sun gear 3, and described the first screw rod 1, the second screw rod 2 both sides are connected with planetary reducer lid 100.
Described the first screw rod 1 is connected to planetary reducer Gai100 center by deep groove ball bearing.Described the second screw rod 2 is connected on planetary reducer lid 100 by deep groove ball bearing.Described sun gear 3 is connected to planetary reducer lid 100 outer rims by angular contact bearing.
Motor is arranged on the first screw rod 1 as input shaft, drives the first screw rod 1 to turn round, and the helicoid of the first screw rod 1 engages with three the second screw rods 2, thereby makes the second screw rod 2 drive sun gear 3 to export.The planetary reducer convenient processing and manufacture of power screw, cost is low, compact structure, stable drive, the life-span is long, and installation precision is high.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
