Abstract
The invention relates to a multi-stage planetary reducer. The multi-stage planetary reducer comprises a shell, a cover, an anti-rotating pin, an input support bearing, a multi-stage planetary transmission mechanism, wherein the multi-stage planetary transmission mechanism is arranged in the shell; the cover is used for sealing; the anti-rotating pin is arranged between the fixing gear rings of the multi-stage transmission mechanism and the shell; a spacer sleeve is arranged between each stage of planet carrier and the shell; the thickness of each spacer sleeve is larger than the thickness of the corresponding planet carrier; a positioning ring is arranged between each spacer sleeve and the corresponding fixing gear ring; the positioning rings ensure that gaps exist between the planet carriers and planet gears of every two adjacent planetary transmission mechanisms. By adopting the multi-stage planetary reducer, the defects in the prior art are overcome; axial positioning is realized for each stage of planetary carrier and the corresponding planet gear; and the friction contact area of the reducer is reduced, so that the transmission efficiency of the reducer is effectively improved.
Description
Technical field
The present invention relates to a kind of planetary reducer, especially a kind of Multi-stage minitype planetary reducer improving sliding bearing.
Background technique
As shown in Figure 1, generally in order to make compact structure, multistage planet retarder adopts planetary pinion at different levels/planet carrier axial float to typical multistage planet reducer structure, there is no axially locating, and the axially locating mode finally blocked by housing is located.In order to ensure that gear can rotate, reserved certain axial clearance after needing gear at different levels to install, but this orientation type can not ensure that between every grade of planet, gap is all even, even there is the situation that indivedual level planet gap is little especially, and because planetary pinion is outside own axes rotation, also revolve round the sun around retarder axis with planet carrier, so except contacting with planet carrier at the corresponding levels, also contact with the another primary planet carrier of axially locating, very large sliding friction can be caused when therefore working, retarder efficiency is reduced greatly.
Summary of the invention
The present invention uses by invention is a kind of the Multi-stage minitype planetary reducer improving axially locating, realizes the rubbing contact area reducing retarder, thus improves retarder transmission efficiency.
Concrete technological scheme of the present invention is, described multistage planet retarder comprises housing, lid, stop pin, input spring bearing, multistage planet driving mechanism, described multistage planet driving mechanism comprises central gear shaft, planetary pinion, planet carrier, planet carrier shaft, fixed gear ring, multistage planet driving mechanism is arranged in housing, closed by cap seal, stop pin is provided with between fixed gear ring in multistage planet driving mechanism and housing, first order central gear shaft in multistage planet driving mechanism is arranged on by input spring bearing and covers, spacer sleeve is provided with between the planet carrier of every one-level and housing, described thickness of analysing spacer sleeve is greater than the thickness of planet carrier, positioning ring is provided with between described spacer sleeve and fixed gear ring, positioning ring ensures to there is gap between the planet carrier of adjacent two epicyclic transmission mechanisms and planetary pinion.Described planet carrier shaft is arranged to pin shape, and is arranged on planet carrier by planet carrier pivot pin by planetary pinion.Described planet carrier is arranged to identical with planetary pinion number polyhedron-shaped.
The present invention is provided with positioning ring and spacer sleeve, axially locating has been carried out to planetary pinion, planet carrier, avoid in planetary pinion process of revolution and contact with other planet carrier, eliminate the friction phenomenon existed in prior art, described planet carrier shaft is pin, ensure that planetary axially locating, planet carrier is made polyhedron-shaped, further reduce the area of contact with two positioning rings.Instant invention overcomes deficiency of the prior art, make the planet carrier of every one-level, planetary pinion all achieves axially locating, decrease the rubbing contact area of retarder, thus effectively improve retarder transmission efficiency.
