Abstract
Provided is a reduction gearbox structure, comprising a main shaft. The main shaft is provided with a gear inner board and a gear outer board at intervals, between which a gear middle board is disposed. The main shaft disposed between the gear middle board and the gear outer board is provided with a sun gear through a first bearing. A step disposed at the outer end of the sun gear is provided with the gear outer board through the second bearing. The periphery of the step of the sun gear is provided with a plurality of pin holes, and the pin traverses through the pin hole and is fixed to a rack. A plurality of long gear shafts are disposed between the gear inner board and the gear outer board. One end of the long gear shaft is provided with an axle gear, and the other end is provided with outer teeth. The outer teeth are engaged with the sun gear. A plurality of short gear shafts are disposed between the gear inner board and the gear middle board, and the upper teeth of the short gear shaft are engaged with the axle gear. The reduction gearbox structure is advantageous in that a planetary gear train is adopted, and the output of different rotating speed of each short gear shaft and each long gear shaft can be conveniently achieved; use is convenient and reliable; work is stable and cost is low.
Description
Technical field
The utility model relates to reducing gear technical field, especially a kind of gearbox structure.
Background technique
In materials in the tube course of working, conventionally need materials in the tube to rotate, its rotational speed is determined according to different materials in the tube demands, in prior art, the reducing gear adopting, its output terminal can only be controlled the rotational speed of an output shaft, in the processing of materials in the tube, often need the rotation of many axles or roller, need many group reducing gears, increased cost, make machine construction complicated.
Model utility content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of gearbox structure rational in infrastructure, thereby realizes easily the different rotating speeds of many output shafts, easy to use, reliable, good stability, and compact structure, takes up room little.
The technological scheme that the utility model adopts is as follows:
A kind of gearbox structure, comprises main shaft, and on described main shaft, interval is provided with boxboard and the outer boxboard of gear in gear, in described gear, between the outer boxboard of boxboard and gear, is provided with boxboard in gear; In gear, outside boxboard and gear, the main shaft between boxboard is installed sun gear by clutch shaft bearing, gear outer container plate is installed by the second bearing by the step place of described sun gear outer end, on the circumferential surface of described sun gear step, have multiple pin shaft holes, pin is fixed through pin shaft hole and frame; Multiple spool gear axles are installed between boxboard outside boxboard and gear in gear, and one end of described spool gear axle is axle gear, and the other end is external tooth, and described external tooth engages with sun gear; Multiple short gear axles are installed between boxboard in boxboard and gear in gear, and on described short gear axle, tooth engages with axle gear.
Further improvement as technique scheme:
The output terminal of described short gear axle and spool gear axle is connected with the roller of required rotation by cardan shaft respectively.
The beneficial effects of the utility model are as follows:
The utility model compact structure, reasonable, adopts planetary gear train, realizes easily the output of each short gear axle and each spool gear axle different rotating speeds, easy to use and reliable, working stability, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Wherein: 1, boxboard in gear; 2, axle gear; 3, spool gear axle; 4, external tooth; 5, short gear axle; 6, sun gear; 7, boxboard in gear; 8, the outer boxboard of gear; 9, clutch shaft bearing; 10, the second bearing; 11, pin shaft hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the gearbox structure of the present embodiment, comprise main shaft (not shown in FIG.), the upper interval of main shaft (not shown in FIG.) is provided with boxboard 1 and the outer boxboard 8 of gear in gear, in gear, between the outer boxboard 8 of boxboard 1 and gear, is provided with boxboard 7 in gear; In gear, outside boxboard 7 and gear, the main shaft between boxboard 8 is installed sun gear 6 by clutch shaft bearing 9, gear outer container plate 8 is installed by the second bearing 10 by the step place of sun gear 6 outer ends, on the circumferential surface of sun gear 6 steps, have multiple pin shaft holes 11, pin is fixing through pin shaft hole 11 and frame (not shown in FIG.); Multiple spool gear axles 3 are installed between boxboard 8 outside boxboard 1 and gear in gear, and one end of spool gear axle 3 is axle gear 2, and the other end is external tooth 4, and external tooth 4 engages with sun gear 6; Multiple short gear axles 5 are installed between boxboard 7 in boxboard 1 and gear in gear, and on short gear axle 5, tooth engages with axle gear 2.
The output terminal of short gear axle 5 and spool gear axle 3 is connected with the roller of required rotation by cardan shaft respectively.
In actual using process, main shaft (not shown in FIG.) rotates by power resources, drive whole speed reducer rotation, because sun gear 6 is fixed on frame (not shown in FIG.) above, sun gear 6 does not rotate, because external tooth 4 engages with sun gear 6, external tooth 4 rotates, and rotates the tooth engagement driving on axle gear 2 and short gear axle 5 with the axle gear 2 that external tooth 4 is coaxial, drive the rotation of short gear axle 5, realized the rotation of short gear axle 5 and spool gear axle 3.Easy to use, reliable.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
