Abstract
The utility model relates to a precise speed reducer with adjustable speed, which comprises a stepless variator. An output shaft of the stepless variator and an input shaft of a planet gear speed reducer are in splicing linkage; one end of the input shaft of the planet gear speed reducer serves as a sun wheel of the planet gear speed reducer; the sun wheel is meshed with a planet wheel; the planet wheel is meshed with an annular gear; a pin shaft of the planet wheel is connected with a planet carrier; and the output shaft of the planet gear speed reducer is linked by the planet carrier. In the utility model, the defects that a common speed reducer cannot have a free variable-speed operation function and a high-precision repositioning function simultaneously, and moreover, the meshed gap of the precise speed reducer is larger, the concentricity cannot be ensured and the bearing capacity is lower in the prior art are overcome. The utility model has the advantages of compact structure, small meshed gap, high concentricity and high bearing capacity.
Description
Technical field
The utility model relates to the accurate speed reducer of a kind of variable-speed.
Background technique
Traditional various speed reducers, the function that all can not possess free changed speed operation and highi degree of accuracy resetting simultaneously, common speed reducer is for example: cylindrical gears, cone gear, cycloidal-pin wheel, worm and gear, common involute planet gear or the like, its back lash is all bigger, concentricity can not guarantee, bearing capacity is also lower, can not satisfy the requirement of precision equipment.
Summary of the invention
Common speed reducer can not possess free changed speed operation and highi degree of accuracy resetting function simultaneously in the prior art in order to overcome, and the gap of its engagement is bigger, concentricity can not guarantee, the problem that bearing capacity is also lower, the utility model provides a kind of variable-speed accurate speed reducer, the compact structure of the accurate speed reducer of this variable-speed, can possess free changed speed operation and highi degree of accuracy resetting function simultaneously, and the gap of its engagement is little, guarantee concentricity, improved bearing capacity.
The technological scheme that its technical problem that solves the utility model adopts is: comprise electrodeless variable-speed, the input shaft grafting interlock of the output shaft of electrodeless variable-speed motor and planet-gear speed reducer, input shaft one end of planet-gear speed reducer is as the sun gear engagement planet wheel of planet-gear speed reducer, planet wheel engagement ring gear, the bearing pin and the planet carrier of planet wheel join, the output shaft of planet carrier interlock planet-gear speed reducer.
Between bearing pin and the planet wheel bearing is set, links to each other by elastic shaft sleeve between the output shaft of electrodeless variable-speed motor and the input shaft of planet-gear speed reducer.
Ring gear is molded over the shell inner surface of planet-gear speed reducer, and ring gear and housing fuse.
The output shaft of planet carrier and planet-gear speed reducer fuses.
The utility model is by above-mentioned specific design, and speed reducer can possess free changed speed operation and highi degree of accuracy resetting function simultaneously, and the gap with compact structure, engagement is little, concentricity height, 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 electrodeless variable-speed motor 1, the output shaft 2 of electrodeless variable-speed motor 1 and the input shaft 4 grafting interlocks of planet-gear speed reducer 3, input shaft 4 one ends of planet-gear speed reducer 3 are as the sun gear engagement planet wheel 5 of planet-gear speed reducer 3, planet wheel 5 engagement ring gears 6, the bearing pin 12 and the planet carrier 7 of planet wheel 5 join, the output shaft 8 of planet carrier 7 interlock planet-gear speed reducers 3, between bearing pin 12 and the planet wheel 5 bearing 9 is set, links to each other by elastic shaft sleeve 11 between the output shaft 2 of electrodeless variable-speed motor 1 and the input shaft 4 of planet-gear speed reducer 3.Ring gear 6 is molded over housing 10 internal surfaces of planet-gear speed reducer 3, and ring gear 6 fuses with housing 10, and planet carrier 7 fuses with the output shaft 8 of planet-gear speed reducer 3.The characteristics of integrative-structure 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 1, and also boundary dimension reduces.Structure of the present utility model is simpler than the speed reducer of traditional planetary structure: the dead in line of the output shaft 2 of planetary bevel-type electrodeless variable-speed motor 10, sun gear input shaft 4, ring gear 6 and planet carrier 7, output shaft 8, output shaft 2 is packed in the sun gear input shaft 4, clamp by elastic shaft sleeve 11, sun gear input shaft 4 reaches radial location by the cooperation and the elastic shaft sleeve 11 of external diameter in the bearing, planet carrier 7, output shaft 8 reach radial location by the cooperation of external diameter in the bearing, thereby guarantee the coaxality of whole moving system, improve the running accuracy of speed reducer.Operating noise of the present utility model is low, maximum noise≤70db, and 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 5 rotations by sun gear input shaft 4, planet wheel 5(revolution) drive planet carrier 7, output shaft 8 rotations (rotation) again with ring gear 6 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 speed reducer of the utility model variable-speed 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 speed reducer of the utility model variable-speed.
