Abstract
The utility model discloses a speed reduction transmission mechanism of a bending machine deflection compensation motor, which comprises a motor rotor shaft, a worm, a worm wheel and an output shaft, wherein the worm wheel is mounted on the output shaft; the worm is engaged with the worm wheel; and the worm extends from the motor rotor shaft to form an integral shaft. By adopting the above technical scheme, as the motor rotor shaft and the worm form an integral structure, coaxiality is high, and vibration is small and operation noise is small during the speed reduction transmission process.
Description
[technical field]
The utility model relates to a kind of deflection compensation motor for bender, refers in particular to a kind of speed reduction gearing of bender deflection compensation motor.
[background technology]
Bender is a kind of processing equipment with metal blank straight line bending and molding under cold conditions, the mould that bender uses is straight line, sleeve configuration, because the frame of supporting mould, the reason of slide block and workbench etc. self rigidity, be difficult to avoid certain amount of deflection to occur, cause the workpiece bending angle small in ends, phenomenon broad in the middle, therefore need to carry out deflection compensation, then needing during deflection compensation provides the motion transmission of power source and speed reduction gearing to be achieved by the deflection compensation motor of bender, and existing bender deflection compensation motor and reduction box are split-type structural, the rotor axis of electric of bender deflection compensation motor stretches in the worm screw of reduction box, both connect by flat key, the shortcoming that forms after connecting is that the axiality of rotor axis of electric and worm screw is subject to restriction to a certain degree, causes these speed reduction gearing vibrations large, the deficiency that noise is large.
In view of this, the speed reduction gearing of existing bender deflection compensation motor is needed improvement badly.
[utility model content]
The deficiency that the utility model exists for above-mentioned prior art and a kind of speed reduction gearing of bender deflection compensation motor is provided.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
The speed reduction gearing of bender deflection compensation motor comprises rotor axis of electric, worm screw, worm gear and axle shaft, and worm gear is installed on the axle shaft, the worm and wheel engagement, and its improvement is: described worm screw extends to form on rotor axis of electric and is integrated axle.
Above-mentioned axle shaft is hollow shaft.
The gearratio of above-mentioned worm and wheel is 1: 29.
Compared with prior art, the utlity model has following beneficial effect:
Because having cancelled flat key between rotor axis of electric and the worm screw connects, after both become one structure, axiality is high, thereby the vibrations when deceleration transmission are little, operating noise is little, thus, can realize bender deflection compensation motor and the reduction box formula structure that becomes one, compared with prior art, embody progressive of the present utility model.
[description of drawings]
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
[embodiment]
Seeing also shown in Figure 1ly, is preferred embodiment of the present utility model.
The speed reduction gearing of bender deflection compensation motor comprises rotor axis of electric 11, worm screw 12, worm gear 2 and axle shaft 3, and worm gear 2 is installed on the axle shaft 3, worm screw 12 and worm gear 2 engagements, and described worm screw 12 extends to form on rotor axis of electric 11 and is integrated axle.
After both became one structure, axiality was high, thereby the vibrations when deceleration transmission are little, operating noise is little, and had embodied the characteristics of good rigidly after worm screw 12 and rotor axis of electric 11 formations one overall structure.
For ease of axle shaft 3 installation load, output shaft 3 just is designed to hollow shaft structure.
During implementation, the gearratio of worm screw 12 and worm gear 2 need to design, and in the present embodiment, both gearratios are 1: 29.
For strengthening braking effect, to realize tapping into the row braking for bender deflection compensation motor straight, advantageously, can electromagnetic brake 4 be installed at rotor axis of electric 11, to overcome the defective of braking retardation.
Although the utility model discloses with specific embodiment, but it is not to limit the utility model, any those skilled in the art has done under the prerequisite that does not break away from design of the present utility model and scope is equal to displacement, or equivalent variations and the modification done under the prerequisite according to design of the present utility model and scope, all should still belong to the category that this patent is contained.
Claims (3)
1. the speed reduction gearing of a bender deflection compensation motor, comprise rotor axis of electric, worm screw, worm gear and axle shaft, worm gear is installed on the axle shaft, the worm and wheel engagement, and it is characterized in that: described worm screw extends to form on rotor axis of electric and is integrated axle.
2. speed reduction gearing according to claim 1, it is characterized in that: described axle shaft is hollow shaft.
