It is less and produce the lever arm shaft gearing device of the bigger bending machine of torsion that the purpose of this utility model provides a kind of relative volume.
The purpose of this utility model is achieved in that the lever arm shaft gearing device of bending machine, it comprises board, axle bed and has lever arm and the fixed arm that anchor clamps clamping tubing carries out bend pipe, axle bed is positioned at board one end, and be provided with a fixed arm, and be provided with rotating shaft and lever arm in the axle bed, it is characterized in that: this rotating shaft has a wandering star wheel shaft, the wandering star pinion is arranged on the wandering star wheel shaft, connections that be meshed with gear segment of wandering star pinion by sun gear shaft top section, and the wandering star pinion is outward and the sun ring gear that the axle bed of fixed arm the sets firmly connection that is meshed.
Above-mentioned design, the sun gear shaft that is connected with by power source by this utilizes a plurality of wandering star pinions and sun ring gear to obtain the output of high torsion, drives lever arm 14 starts that the pinion gear axle sets firmly up and down, reaches volume and reduces and still have a bigger effect of torsion.
Below by drawings and Examples the utility model is described further again:
Fig. 1 is the utility model three-dimensional exploded view;
Fig. 2 analyses and observe the combination schematic diagram for the utility model;
Fig. 3 is the utility model schematic top plan view;
Fig. 4 makes up another embodiment schematic diagram for the utility model;
The lever arm rotating shaft drive mechanism schematic diagram of Fig. 6,7 existing bending machines;
Shown in Fig. 1-4: the utility model comprises board 11, axle bed 12 and has lever arm 14 and the fixed arm 15 that anchor clamps clamping tubing carries out bend pipe, axle bed 12 is positioned at board 11 1 ends, and be provided with a fixed arm 15, and be provided with rotating shaft and lever arm 14 in the axle bed 12, it is characterized in that: this rotating shaft has a wandering star wheel shaft 2, wandering star pinion 242 is arranged on the wandering star wheel shaft 2, wandering star pinion 242 connections that be meshed with gear segment 41 by sun gear shaft 4 top section, and wandering star pinion 242 is outward and the sun ring gears 3 that the axle bed 12 of fixed arm 15 the sets firmly connection that is meshed.Wherein, pinion gear axle 2 tops are provided with projection 21, and projection is established the end cover 141 that is fixed at lever arm 14 for 21 groups.Wherein, be combined with upper bearing (metal) 26 in the pinion gear wheel shaft 2 and establish for 12 groups, be installed with sun ring gear 3 and combined cover 5 downwards in regular turn, and be provided with a lower bearing 27 and the pinion gear 2 that is pivoted in the combined cover 5 with axle bed.Wherein, pinion gear 2 bottoms just can be inserted fixing for the hole 61 of grillage 6, and grillage 6 directly is fixedly arranged on lever arm 14 bottoms.Wherein, the projection 21 of wandering star wheel shaft 2 is positioned at end face 22 central authorities, is provided with the screw 221 of tap bolt 222 on the end face 22 around the projection 21; Be provided with at least three pin-and-holes 231 that supply pivot pin 232 to insert in end face 232; Establish several breach of inserting wandering star pinion 242 241 on each pin-and-hole 231 relative diameter of axle 24; Establish a two bearings 251,252 and a clasp 253 in the mesopore 25, when making 4 groups of sun gear shafts establish in it, outer tooth ring 40 and each wandering star pinion 242 engagement in gear segment 41 by chance cooperates, and sun gear shaft 4 in addition 42 of the joining sections of end convexedly stretch in the external power source in bottom of pinion gear axle 2.Pass the bottom face that is screwed into axle sleeve 151 behind the hole 32 of the hole 52 of combined cover 5 and the flange 31 on the sun ring gear 3 with bolt 51, the grillage 6 that will be fixedly arranged on lever arm 14 bottoms again utilizes hole 61 for the end section in conjunction with wandering star wheel shaft 2, be that lever arm sets firmly with wandering star wheel shaft 2 about in the of 14, can do relative swing with fixed arm 15 by this and carry out bend pipe.
