Abstract
The utility model relates to a precise planet-gear speed reducer which comprises a shell; one end of an input shaft is taken as a sun gear of the planet-gear speed reducer, and the sun gear is meshed with a planet wheel which is meshed with an inner gear ring; the inner gear ring is molded on the inner surface of the shell and is connected with the shell to form a whole; and a pin shaft of the planet wheel is connected with a planet carrier which is linked with an output shaft. The precise planet-gear speed reducer overcomes the defects that the common speed reducer in the prior art has larger meshing clearance and lower born input rotating speed, and can not meet the using requirement of precision equipment. By adopting the design, the speed reducer meets the different using requirements of various kinds of precision equipment, and has the advantages of being compact in structure, small in meshing clearance, high in concentricity and accuracy of repeated location and strong in carrying capacity.
Description
Technical field
The utility model relates to a kind of accurate planet-gear speed reducer.
Background technique
For example cylindrical gears, cone gear, cycloidal-pin wheel, the stepless time adjustment of traditional various speed reducers, worm and gear, common involute planet gear or the like, its back lash is all bigger, the input speed that bears is lower, normal conditions are not higher than 2800r/min, so all can not satisfy the usage requirement of precision equipment.
Summary of the invention
For the back lash that overcomes common speed reducer in the prior art all bigger, the input speed that bears is lower, can not satisfy the problem of the usage requirement of precision equipment, the utility model provides a kind of accurate planet-gear speed reducer, the compact structure of this precision planet-gear speed reducer, the gap of engagement be little, guarantee concentricity, the repetitive positioning accuracy height, improved bearing capacity.
The technological scheme that its technical problem that solves the utility model adopts is: comprise housing, input shaft one end is as the sun gear engagement planet wheel of planet-gear speed reducer, planet wheel engagement ring gear, the shell inner surface that ring gear is molded over, ring gear and housing fuse, the bearing pin and the planet carrier of planet wheel join, planet carrier interlock output shaft.
Input shaft links to each other with the output shaft of electrodeless variable-speed motor by elastic shaft sleeve.The utility model is by above-mentioned specific design, and speed reducer can satisfy the usage requirement of precision equipment, and the gap with compact structure, engagement is little, the precision height of concentricity and resetting, the advantage that bearing capacity is strong.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises housing, input shaft 2 one ends are as the sun gear engagement planet wheel 3 of planet-gear speed reducer, planet wheel 3 engagement ring gears 4, housing 1 internal surface that ring gear 4 is molded over, ring gear 4 fuses with housing 1, and the bearing pin 5 and the planet carrier 6 of planet wheel 3 join planet carrier 6 interlock output shafts 7.Input shaft 2 links to each other with the output shaft 9 of electrodeless variable-speed motor 8 by elastic shaft sleeve 10.The fuse characteristics of structure of ring gear 4 and housing 1 are to reduce sideshake, increase rigidity, guarantee concentricity, guarantee repetitive positioning accuracy, improve bearing capacity, can free speed change after joining with electrodeless variable-speed motor 8, and also boundary dimension reduces.Input speed height of the present utility model, maximum input speed can be up to 10000r/min.Noise is low simultaneously, maximum noise≤70db.The backhaul sideshake is little of single-stage≤8 arc branches, twin-stage≤12 arc branches.Overload capacity is more than three times of common speed reducer.Working principle of the present utility model is the same with the speed reducer working principle of traditional planetary structure, drive planet wheel 3 rotations by sun gear input shaft 2, planet wheel 3(revolution) drive planet carrier 6, output shaft 7 rotations (rotation) again with ring gear 4 engagements, reaching slows down increases the purpose of turning round.Single-stage, twin-stage, multistage structure is identical, is not giving unnecessary details one by one.Above-described embodiment only is that the preferred implementation to the accurate planet-gear speed reducer of the utility model is described; be not that design and scope to model utility limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain of the accurate planet-gear speed reducer of the utility model.
