Abstract
The utility model discloses a kind of two stage composite planetary gear transmission mechanism, primary planet pinion structure and secondary planetary gear structure including casing and its inside, input shaft is on the right side of the casing and inserts that primary planet pinion structure is central to be connected with each primary planet gear teeth, input shaft is entering setting bearing one at casing, each primary planet wheel rotating shaft is fixedly 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 fixedly 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.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 Gear Transmission knot
Structure, is applicable to the reductor of the extrusion machine equipment of brick-tile industry.
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：For above-mentioned problem, there is provided a kind of two stage composite planet tooth
Drive mechanism is taken turns, structure is simpler, 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 gear transmission mechanism, includes the primary planet pinion structure and two of casing and its inside
Level planetary gear construction, input shaft left end enters the center for being inserted into primary planet pinion structure as one-level on the right side of casing
Sun gear is connected with each primary planet gear teeth, and input shaft is entering setting bearing one at casing, the rotating shaft point of each primary planet wheel
Be not fixedly connected with primary planet carrier right-hand member, the left end of primary planet carrier insertion secondary planetary gear structure center as two grades too
Sun wheel is connected with each secondary planet gear teeth, and the rotating shaft of each secondary planet wheel is fixedly connected with secondary planet frame respectively, the input
The end of axle left end continues across primary planet pinion structure and inserts primary planet carrier right-hand member and set bearing between
Two realize rotation 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.
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
Bearing two, 7 be bearing three, and 8 be bearing four, and 9 be secondary planet wheel, and 10 be secondary planet frame.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
Embodiment：
As shown in figure 1, a kind of two stage composite planetary gear transmission mechanism, including casing 1 and its primary planet of inside
Gear structure and secondary planetary gear structure, the left end of input shaft 4 enters from the right side of casing 1 is inserted into primary planet pinion structure
Center be connected as one-level sun gear with each tooth of primary planet wheel 5, input shaft 4 entrance casing 1 at setting bearing 1, respectively
The rotating shaft of primary planet wheel 5 is fixedly connected with the right-hand member of primary planet carrier 2 respectively, the left end insertion secondary planet of primary planet carrier 2
Gear structure center is connected as secondary solar gear with each tooth of secondary planet wheel 9, the rotating shaft of each secondary planet wheel 9 respectively with two grades
Planet carrier 10 is fixedly connected, and the end of the left end of input shaft 4 continues across primary planet pinion structure and inserts primary planet
The right-hand member of frame 2 and between setting bearing 26, which are realized, rotates connection.Between the primary planet carrier 2 and secondary planet frame 10
Also set up bearing 37 and realize rotation connection.Bearing 48 is also set up between the secondary planet frame 10 and casing 1 and realizes the company of rotation
Connect.The casing 1 is up and down to cuing open detachable connection between formula, two parts.In Fig. 1 of the present embodiment, two grades of rows
Carrier 10 traverses each two ends of secondary planet wheel 9, therefore, can be in secondary planet wheel 9 and the left end tooth link position of primary planet carrier 2
Both sides are respectively provided with bearing 37.
