Abstract

The utility model discloses a gear synchronizing mechanism of a reducer. The gear synchronizing mechanism comprises a torsion balancing shaft (1), and a gear shaft (2) is sleeved outside the left portion of the torsion balancing shaft (1). The gear synchronizing mechanism is characterized in that an inner taper sleeve (3) with the left outer diameter larger than the right outer diameter is sleeved on the right portion of the torsion balancing shaft (1), an outer taper sleeve (4) is sleeved outside the inner taper sleeve (3) in matching mode, an outer cover (5) is sleeved outside the outer taper sleeve (4), and the left end faces of the inner taper sleeve (3) and the outer cover (5) are both attached to the right end face of the gear shaft (2) closely. The outer cover (5) is fixed on the gear shaft (2) through a bolt, and a pressing plate (6) is arranged on the right end face of the outer taper sleeve (4) and fixed on the torsion balancing shaft (1) through a bolt. The gear synchronizing mechanism is reasonable in design, simple in structure, easy to implement, low in manufacture cost, easy in machining of parts and easy to assemble and reduces assembling errors and gear synchronizing errors.

Description

The gear synchronization mechanism of speed reducer
Technical field
The utility model relates to a kind of parts of large-scale speed reducer, particularly a kind of gear synchronization mechanism of speed reducer.
Background technique
The gear synchronization mechanism of traditional speed reducer (as shown in Figure 1) comprises torsion balance axle (1), outside the left part of torsion balance axle (1), is set with gear shaft (2); The right part of said torsion balance axle (1) is set with a tapered sleeve (7) outward, and this tapered sleeve (7) is fixed on the right side of gear shaft (2) through first pin (8), second pin, bolt and the pressing plate etc., on the one hand; This tapered sleeve (7) volume is big, and weight is big, is inconvenient to process; On the other hand, when assembling, need earlier tapered sleeve to be put; After then torsion balance axle and gear shaft being worked good synchronously, make second locating stud, remove the hole of boring first pin behind the part; And then tapered sleeve assembled up, owing to there is machining error, cause the gear that allotment is good already to have error synchronously like this.
The model utility content
The utility model technical problem to be solved is to provide a kind of convenient processing, reduces the gear synchronization mechanism of the speed reducer of assembly error.
To achieve these goals; The technological scheme of the utility model is following: a kind of gear synchronization mechanism of speed reducer; Comprise torsion balance axle (1), outside the left part of torsion balance axle (1), be set with gear shaft (2), it is characterized in that: the right part of said torsion balance axle (1) is set with the inner conical drogue (3) of a left part external diameter greater than the right part external diameter outward; Said inner conical drogue (3) fit on is set with an external conical sleeve (4); Said external conical sleeve (4) is outer to be set with an overcoat (5), and the left side of said inner conical drogue (3) and overcoat (5) all is close on the right side of gear shaft (2), and said overcoat (5) is through being bolted on the gear shaft (2); The right side of said external conical sleeve (4) is provided with pressing plate (6), and said pressing plate (6) is through being bolted on the torsion balance axle (1).
Adopt technique scheme, elder generation suit inner conical drogue and overcoat on the torsion balance axle carry out coaxial debugging then before debugging; After treating that debugging is worked good, with bolt and pressing plate external conical sleeve is compressed just passablely, need not remove part processing again; Reduce assembly error, thereby reduce the gear synchronization error, in addition; Take into a former tapered sleeve apart inner conical drogue, external conical sleeve and overcoat, make the very good processing of part.
In technique scheme, fix more firmly in order to make overcoat, reduce same axis error, the two ends of said pressing plate (6) extend to outside the external conical sleeve (4), and its extending end is positioned on the right side of overcoat (5).
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, low cost of manufacture, and part processing is easy, and assembling reduces assembly error easily, has reduced the gear synchronization error.
Description of drawings
Fig. 1 is the structural representation before improving;
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Embodiment 1, and is as shown in Figure 2, and the gear synchronization mechanism of the speed reducer of the utility model mainly is made up of parts such as torsion balance axle 1, gear shaft 2, inner conical drogue 3, external conical sleeve 4, overcoat 5, pressing plate 6 and bolts.
Outside the left part of torsion balance axle 1, be set with gear shaft 2, this is an existing technology, does not do at this and gives unnecessary details.Key is: the right part of said torsion balance axle 1 is set with the inner conical drogue 3 of a left part external diameter greater than the right part external diameter outward; Said inner conical drogue 3 fit ons are set with the external conical sleeve 4 of a right part external diameter greater than the left part external diameter; Be set with an overcoat 5 outside the said external conical sleeve 4; The left side of said inner conical drogue 3 and overcoat 5 all is close on the right side of gear shaft 2; Said overcoat 5 is through being bolted on the gear shaft 2, and the right side of said external conical sleeve 4 is provided with pressing plate 6, and said pressing plate 6 is through being bolted on the torsion balance axle 1.The two ends of said pressing plate 6 extend to outside the external conical sleeve 4, and its extending end is positioned on the right side of overcoat 5.

Claims (2)

1. the gear synchronization mechanism of a speed reducer; Comprise torsion balance axle (1); Outside the left part of torsion balance axle (1), be set with gear shaft (2); It is characterized in that: the right part of said torsion balance axle (1) is set with the inner conical drogue (3) of a left part external diameter greater than the right part external diameter outward, and said inner conical drogue (3) fit on is set with an external conical sleeve (4), the outer overcoat (5) that is set with of said external conical sleeve (4); The left side of said inner conical drogue (3) and overcoat (5) all is close on the right side of gear shaft (2); Said overcoat (5) is through being bolted on the gear shaft (2), and the right side of said external conical sleeve (4) is provided with pressing plate (6), and said pressing plate (6) is through being bolted on the torsion balance axle (1).
2. according to the gear synchronization mechanism of the said speed reducer of claim 1, it is characterized in that: the two ends of said pressing plate (6) extend to outside the external conical sleeve (4), and its extending end is positioned on the right side of overcoat (5).
