Abstract

The utility model discloses a reduction gearbox with smooth transmission, which comprises a main reduction gearbox and a resistance adjusting device connected with the output shaft of the main reduction gearbox. When the transmission resistance of the output shaft of the main reduction gearbox changes periodically in a coming and going manner due to the periodic intermittent stress of a driven device, the resistance adjusting device is started to adjust additional resistance into a proper value, so as to ensure that resultant force of the transmission resistance on the output shaft of the main reduction gearbox and the additional resistance is not zero all the time. The resistance, which is not zero all the time, is transmitted to each stage gear pair of the main reduction gearbox, and the gear pairs are under the combined action of the resistance which is not zero all the time and continuous power transmitted by an input shaft all the time, so that the direction of the resultant force is single and not zero all the time, and collision between the gear pairs is avoided. The gear manufacturing accuracy and the assembly precision of the main reduction gearbox are not required to be further improved, and the smooth transmission of the output shaft of the main reduction gearbox is realized through the resistance adjusting device, so that the manufacture cost of the main reduction gearbox is greatly reduced; the resistance adjusting device can be controlled manually, and is flexible to use.

Description

The speed reducer of stable drive
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of speed reducer with the transmission resistance adjustment device.
Background technique
In use, its input shaft is driven by power plant various speed reduceres, and output shaft is connected with driven device; The transmission resistance of output shaft is determined by the working resistance of driven device fully.When driven device periodically during interrupted stressed work, the transmission resistance of output shaft also occur thereupon by large to zero again to greatly again to zero cyclically-varying; Because there is backlash in the driving gears at different levels in speed reducer, under the continuous driving power joint effect of the transmission resistance cut in and out and input shaft, because the inertia of gear itself causes collision between gear pair and the vibration of output shaft, the transmission speed that this vibration causes output shaft and driven device is not steadily and affect the normal operation of driven device.
Current existing solution is the assembly precision that reduces the backlash of gear pair and improve gear accuracy of manufacturing and speed reducer when design, when the cyclically-varying that output shaft transmission resistance cuts in and out, less backlash can reduce collision and the vibration between gear pair; But require to have rational backlash with requirements such as formation lubricant films during because of accuracy of manufacturing restriction and gear pair transmission, backlash can only reduce and can't eliminate, therefore the collision between gear pair and vibration also can only reduce and can not eliminate, and because of the assembly precision that improves gear accuracy of manufacturing and speed reducer, the speed reducer manufacture cost are significantly raise simultaneously.
The model utility content
The purpose of this utility model is to provide a kind of resultant direction that can make gear pair single and total non-vanishing, the speed reducer that operates steadily.
The speed reducer of this stable drive that the utility model provides, it comprises the drag regulator that main speed reduction box is adjustable with the resistance be connected with the main speed reduction box output shaft.
Between described main speed reduction box and drag regulator, be connected with secondary speed reducer, drag regulator is connected on the output shaft of secondary speed reducer, so that drag regulator obtains best number of moving part.
Described main speed reduction box and secondary speed reducer can be that any one or the multiple combination in one or more levels cylindrical gears speed reducer and cone gearbox, worm reduction box, planetary gear reduction box, cycloidal pinwheel reduction box, harmonic reduction gear case, three ring speed reduceres forms.
Described drag regulator can be any one in eddy current damper, electromagnetic brake, magnetic powder brake, oil hydraulic pump.
The utility model has installed the adjustable drag regulator of resistance additional on the output shaft of main speed reduction box, when driven device when periodically interrupted stressed work causes cyclically-varying that the transmission resistance of main speed reduction box output shaft cuts in and out, open drag regulator additional drag is adjusted to desired value, make always non-vanishing with joint efforts after on the output shaft of main speed reduction box of this additional drag and the acting in conjunction of transmission resistance.Non-vanishing resistance passes to every grade of gear pair of main speed reduction box through output shaft, the gear vice president is by non-vanishing resistance and the continuous dynamic combined action that transmits through input shaft, and resultant direction is single and always non-vanishing, so just can not collide between gear pair.
With prior art, compare, main speed reduction box of the present utility model does not need additionally to improve the assembly precision of gear accuracy of manufacturing and speed reducer, by drag regulator, realizes the steady transmission of main speed reduction box output shaft, greatly reduces the manufacture cost of main speed reduction box; Use flexibly, but the drag regulator manual control when not working, driven device can be closed drag regulator and be reduced energy consumption; During driven device work, open transmission resistance adjustment device the artificial drag size of adjusting, to reach steady transmission optimum efficiency.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Preferred embodiment, as shown in Figure 1, the speed reducer of this stable drive that the utility model provides, it comprises main speed reduction box 1, secondary speed reducer 2 and drag regulator 3.The input shaft 5 of main speed reduction box 1 is connected with power plant 4, and an end of its output shaft 6 is connected with driven device 7, and the other end is connected with auxiliary transmission 2, and the output shaft of auxiliary transmission 2 is connected with drag regulator 3.Main speed reduction box 1 and secondary speed reducer 2 can be that any one or the multiple combination in one or more levels cylindrical gears speed reducer and cone gearbox, worm reduction box, planetary gear reduction box, cycloidal pinwheel reduction box, harmonic reduction gear case, three ring speed reduceres forms.Drag regulator 3 can be any one in eddy current damper, electromagnetic brake, magnetic powder brake, oil hydraulic pump.
The specific works process is as follows: at driven device 7 when periodically interrupted stressed work causes cyclically-varying that the transmission resistance of main speed reduction box 1 output shaft 6 cuts in and out, open drag regulator 3 and additional drag is adjusted to desired value, making total non-vanishing getting final product of making a concerted effort of main speed reduction box 1 output shaft 6 upper driving resistances and additional drag.
Working principle is as follows: non-vanishing resistance passes to every grade of gear pair of main speed reduction box 1 through output shaft 6, gear pair is at any time by non-vanishing resistance and the continuous dynamic combined action that transmits through input shaft 5, the single direction and always non-vanishing of making a concerted effort, so just can not collide between gear pair, the transmission speed of output shaft 6 and driven device 7 will be very steady, thereby guarantee the normal smooth working of drive unit 7.
It is the operating mode of round disk saw that the utility model especially is applicable to driven device.
