Abstract
The utility model discloses a kind of two stage composite planetary reduction gear, including casing, primary planet pinion structure and secondary planetary gear structure, input shaft insertion primary planet pinion structure is central to be connected with each primary planet gear teeth and bearing one is set at casing entering, each primary planet wheel rotating shaft is connected with primary planet carrier respectively, secondary planetary gear structure is central is connected with each secondary planet gear teeth for the insertion of primary planet carrier left end, each secondary planet wheel rotating shaft is connected with secondary planet frame respectively, the input shaft left end end is through primary planet pinion structure and inserts primary planet carrier right-hand member and between setting bearing two realization rotation connection, output shaft enters on the left of casing and is connected with secondary planet frame tooth.Input shaft left end is inserted in primary planet carrier and rotates connection by the utility model, it is ensured that the axiality of primary planet carrier and input shaft, the problem of solving input shaft left end cantilever, and reduces vibration, so as to effective prolonged deceleration machine service life.
Description
Technical field
The utility model is related to a kind of gear transmission technology field, particularly a kind of two stage composite planetary reduction gear.
Background technology
A kind of existing double planetary reduction gear, its input shaft enter decelerator casing after, its termination with each one
Level planetary gear is connected, and input shaft is also connected by a bearing with casing.And primary planet carrier is to keep stable, specially
Door is provided with fixing bearing between input shaft and casing, primary planet carrier is kept stable.
The applicant has found that this existing double planetary reduction gear has following deficiency during using, repairing
Place：
1st, input shaft only one of which bearing is fixed on casing, but because its end stress is big, vibration is obvious, so as to lead
Cause is easily out of order everywhere, has influence on the service life of decelerator；
2nd, fixing bearing is set in primary planet carrier and casing, huge structure is too fat to move, even and if after taking casing apart, due to
The presence of this fixing bearing, it is necessary to just can further be checked, repaired after all taking apart, it is very inconvenient.
Utility model content
Goal of the invention of the present utility model is：Subtract for above-mentioned problem there is provided a kind of two stage composite planet
Fast device, structure is simpler, and more preferably, service life is longer for stability.
The technical solution adopted in the utility model is such：
A kind of two stage composite planetary reduction gear, includes the primary planet pinion structure and secondary planet of casing and its inside
Gear structure, input shaft left end enters the center for being inserted into primary planet pinion structure as one-level sun gear on the right side of casing
It is connected with each primary planet gear teeth, input shaft sets bearing one entering at casing, the rotating shaft of each primary planet wheel is respectively with one
Level planet carrier right-hand member is fixedly connected, the left end of primary planet carrier insertion secondary planetary gear structure center as secondary solar gear with
Each secondary planet gear teeth connection, the rotating shaft of each secondary planet wheel is fixedly connected with secondary planet frame respectively, and output shaft is left from casing
Side enters and is connected with secondary planet frame tooth, and the end of the input shaft left end continues across primary planet pinion structure and inserted
Primary planet carrier right-hand member and between setting bearing two, which are realized, rotates connection.
Input shaft left end is inserted in primary planet carrier and rotates connection by above-mentioned technical proposal, it is ensured that primary planet carrier and
Axiality between input shaft, the problem of solving input shaft left end cantilever, and vibration when reducing rotation, so as to have
Imitate the service life of prolonged deceleration machine.
Connection is rotated preferably, also setting up bearing three between the primary planet carrier and secondary planet frame and realizing.Originally
Double planetary reduction gear bearing three is not set in this position, so the vibration of primary planet carrier is larger, this preferred side
Case further eliminates the factor that vibration is produced.
Connection is rotated preferably, also setting up bearing four between the secondary planet frame and casing and realizing.Twin-stage originally
Planetary reduction gear does not also set bearing four at it between casing, therefore, and the stability of secondary planet frame is also poor, is also to shake
One factor of movable property life.This preferred scheme further eliminates the factor that vibration is produced.Due to secondary planet frame and casing
Between spacing it is larger, for mitigate bearing four size and weight, in casing internal, support frame is first set, then support frame with
Bearing four is set between secondary planet frame.
Preferably, the casing is up and down to cuing open detachable connection between formula, two parts, maintenance is facilitated to check inside
Situation, and without by internal each parts overhaul one by one.
Also rotated and connected by two groups of bearings between the secondary planet frame axle and casing.
Brief description of the drawings
Fig. 1 is stereochemical structure sectional view of the present utility model.
Marked in figure：1 is casing, and 2 be primary planet carrier, and 3 be bearing one, and 4 be input shaft, and 5 be primary planet wheel, and 6 are
