Abstract

The utility model discloses a speed-reducing box of a planet speed-reducing motor. The speed-reducing box comprises a gear box body, wherein the gear box body comprises a front box body and a rear box body; a coupler is arranged in the front box body; a planet carrier is arranged in the rear box body; a planet gear train is arranged in the planet carrier; a sun gear of the planet gear train is connected with the coupler; and a centering bearing is arranged on the planet carrier and supported between the front box body and the rear box body. Because the centering bearing is supported between the front box body and the rear box body, during assembly, the front box body and the rear box body can be centered by the centering bearing, so that the aim of accurate centering is fulfilled.

Description

A kind of speed reducer of planetary reduction gear motor
Technical field
The utility model relates to the speed reducer of planetary reduction gear motor.
Background technique
The speed reducer of planetary reduction gear motor comprises gear housing, and casing and rear box before gear housing comprises are provided with coupling in the preceding casing, are provided with planet carrier in the rear box, are provided with epicyclic train in the planet carrier, and the sun gear of epicyclic train is connected with coupling.The shortcoming that the speed reducer of existing planetary reduction gear motor also exists is: preceding casing and rear box are difficult to accurately centering when mounted, thereby operation causes harmful effect to motor.
Summary of the invention
In order to overcome the above-mentioned deficiency of the speed reducer that has the planetary reduction gear motor now, the utility model provides the speed reducer of a kind of preceding casing and the accurate planetary reduction gear motor of rear cabinet centering.
The technological scheme that the utility model solves its technical problem is: a kind of speed reducer of planetary reduction gear motor; Comprise gear housing; Casing and rear box before described gear housing comprises are provided with coupling in the described preceding casing, are provided with planet carrier in the described rear box; Be provided with epicyclic train in the described planet carrier; The sun gear of said epicyclic train is connected with described coupling, also is provided with a pair of middle (center) bearing on the described planet carrier, and described centering bearings is before described between casing and the rear box.
The beneficial effect of the utility model is: the centering bearings between preceding casing and rear box, when preceding casing and rear box assemble, can be earlier by middle (center) bearing is realized centering, to reach the purpose of accurate centering.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, a kind of speed reducer of planetary reduction gear motor comprises gear housing; Casing 1 and rear box 2 before described gear housing comprises are provided with coupling 3 in the described preceding casing 1, are provided with planet carrier 4 in the described rear box 2; Be provided with epicyclic train in the described planet carrier 4; The sun gear of said epicyclic train is connected with described coupling 3, also is provided with a pair of middle (center) bearing 5 on the described planet carrier 4, described to middle (center) bearing 5 be supported in described before between casing 1 and the rear box 2.
The utility model middle (center) bearing 5 is supported between preceding casing 1 and the rear box 2, when preceding casing 1 assembles with rear box 2, can be earlier by middle (center) bearing 5 is realized centerings, to reach the purpose of accurate centering.
