Description
Technical Field
The utility model belongs to the technical field of the reducing gear box technique and specifically relates to a four-axis double-line drive's reducing gear box.
Background
As is well known, the transmission modes of the currently popular miniature direct current motor reduction gearbox, such as 16GA,20GA,25GA,37GB and other cylindrical reduction gearboxes, are all 2-axis single-line transmission, and are limited by the volume of the box body, the gear module of the transmission and the thickness of the tooth piece are designed to be very small, so that the torque force borne by a single tooth is very limited, and the tooth breakage phenomenon frequently occurs in the reduction transmission process, so that the superior performance of the motor cannot be reflected by the reduction gearbox, and the motor can often output a larger torque force.
Disclosure of Invention
To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a four-axis double-line drive's reducing gear box.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a four-axis double-line transmission's reducing gear box, includes box and motor, the rotating head of motor inserts and has cup jointed a motor gear from box one end, the other end of box is provided with the output shaft, the output shaft is located the inside output gear that is provided with of box, the inside transmission assembly that is provided with two sets of mutual symmetries of box, every group transmission assembly includes first pivot and second pivot, all be provided with the duplicate gear that quantity equals and intermeshing in first pivot and the second pivot, the duplicate gear and the motor gear meshing that first pivot is located the bottom, the duplicate gear and the output gear meshing that the second pivot is located the top.
Preferably, the box includes apron, shell and connecting plate, the shell is installed between apron and connecting plate, all be provided with a plurality of circular recess on apron and the connecting plate, the both ends of first pivot and second pivot all dock in the circular recess, output shaft one end is passed the apron and is arranged in the outside.
Preferably, a ball bearing is arranged between the output shaft and the cover plate.
Due to the adoption of the scheme, the utility model has the advantages that after the forces generated by the motors are decomposed, burdened, transmitted and transmitted by the two groups of mutually symmetrical transmission assemblies, the output gears are effectively prevented from bearing larger torsion, the phenomenon of tooth breakage is prevented, and double-line dispersed transmission is realized; meanwhile, each group of transmission assemblies consists of a first rotating shaft and a second rotating shaft, four-axis dispersed transmission is achieved, linkage output is conducted through a plurality of duplicate gears, four-axis double-line transmission is finally achieved, and the overall bearing capacity is greatly improved.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in fig. 1 to 3, the present embodiment provides a four-axis two-line transmission reduction gearbox, including box 1 and motor 2, a motor gear 3 is inserted and cup jointed from box one end to the rotating head of motor 2, the other end of box 1 is provided with output shaft 4, output shaft 4 is located box 1 inside and is provided with output gear 5, box 1 inside is provided with two sets of mutually symmetrical transmission assemblies 6, every transmission assembly 6 includes first pivot 7 and second pivot 8, all be provided with the duplicate gear 9 that quantity equals and intermeshing on first pivot 7 and the second pivot 8, duplicate gear 9 that first pivot 7 is located the bottommost meshes with motor gear 3, duplicate gear 9 that second pivot 8 is located the topmost meshes with output gear 5.
Further, the box 1 of this embodiment includes a cover plate 10, a housing 11 and a connecting plate 12, the housing 11 is installed between the cover plate 10 and the connecting plate 12, the cover plate 10 and the connecting plate 12 are both provided with a plurality of circular grooves 13, both ends of the first rotating shaft 7 and the second rotating shaft 8 are both butted in the circular grooves 13, and one end of the output shaft 4 penetrates through the cover plate 10 and is disposed outside.
Further, in order to realize the normal rotation of the output shaft 4, a ball bearing 14 is disposed between the output shaft 4 and the cover plate 10.
The concrete during operation of this embodiment, provide power by motor 2 and make its motor gear 3 begin to operate, 6 synchronous transmission through two sets of mutual symmetries transmission assembly afterwards, specifically be first pivot 7 through the duplicate gear 9 and the motor gear 3 meshing of bottommost, then rotate and drive second pivot 8 through duplicate gear 9 and rotate after the first pivot 7 atress, and then realize the decomposition transmission of power, reduce single duplicate gear 9 atress, gather to output gear 5 through two second pivots 8 afterwards, realize four-axis double-line drive, the atress of single duplicate gear of effectual dispersion, can effectually avoid phenomenons such as disconnected tooth, promote whole bearing capacity greatly.
