Abstract
The utility model discloses a speed reducer rigidity inputting flange structure with a backstop. The speed reducer rigidity inputting flange structure with the backstop comprises a speed reducer flange, a motor flange and an input shaft, wherein the speed reducer flange is fixedly connected with the motor flange, the input shaft penetrates through the inner holes of the speed reducer flange and the motor flange; inner holes of the speed reducer flange and the motor flange are respectively provided with bearings, and slewing bearings form between the bearing and the input shaft. The speed reducer rigidity inputting flange structure with the backstop is characterized in that the backstop is arranged between the speed reducer flange and the motor flange, an outer ring of the backstop is fixedly arranged in the inner holes of the speed reducer flange or the motor flange and an inner ring of the backstop is fixedly arranged on an outer circle of the input shaft. The speed reducer rigidity inputting flange structure with the backstop applies to workplaces in which the speed reducer operates in a single direction and revision is avoided when the speed reducer stops. The speed reducer rigidity inputting flange structure with the backstop has the advantages of being small, exquisite and compact in a complete set of structure and free of occupied area and fills the gaps in domestic.
Description
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of rigidity of gear reduction unit input flange structure with non-return device.
Background technique
All can not be with non-return device during domestic four large series reduction gas-distributing motors, perhaps non-return device is installed at the large slow speed turbine stage of speed reducer moment of torsion, causes speed reducer bulky all the time, and structure is too fat to move.And under the actual conditions, a lot of workplaces prevent the oppositely function of reverse, the like this precision of guarantee speed reducer work when needing speed reducer to possess Unidirectional, parking.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of workplace that is applicable to the speed reducer Unidirectional, prevents reverse reverse when stopping, a whole set of structure compact, the rigidity of gear reduction unit input flange structure that does not take up space.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of rigidity of gear reduction unit input flange structure with non-return device, comprise speed reducer flange, motor flange and input shaft, the speed reducer flange is fixedly connected with motor flange, input shaft passes the endoporus of speed reducer flange and motor flange, the endoporus of speed reducer flange and motor flange is respectively equipped with bearing input shaft is formed pivoting support, it is characterized in that: be provided with non-return device between speed reducer flange and the motor flange, the outer ring of non-return device is fixedly installed at the endoporus of speed reducer flange or motor flange, and the inner ring of non-return device is fixedly installed at the cylindrical of input shaft.
In the said structure, non-return device is installed at the inside of rigidity input flange, because non-return device is installed at the high speed level of speed reducer, so moment of torsion is little, because moment of torsion is little, so the model of non-return device is also little, a whole set of structure compact does not take up space.
As preferably, the outer ring of non-return device is fixed by screws in the endoporus of speed reducer flange.The input end of input shaft is established the motor shaft trepanning, and the output terminal of input shaft is established the speed reducer input gear.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by specific embodiment the utility model is described in detail and illustrates:
As shown in the figure, rigidity of gear reduction unit input flange structure with non-return device of the present utility model, comprise speed reducer flange 3, motor flange 7 and input shaft 9, speed reducer flange 3 and motor flange 7 are fixedly connected with by screw, input shaft 9 passes the endoporus of speed reducer flange and motor flange, the endoporus of speed reducer flange and motor flange is respectively equipped with bearing 2,8 pairs of input shafts of bearing 9 form pivoting support, the input end of input shaft 9 is established motor shaft trepanning 10, the output terminal of input shaft 9 is established speed reducer input gear 1, be provided with non-return device between speed reducer flange 3 and the motor flange 7, the outer ring 5 of non-return device is set in the endoporus of speed reducer flange 3 and is fixed by screw 6, and the inner ring 4 of non-return device is set in the cylindrical of input shaft 9 and fixes by flat key.
During the utility model work, the speed reducer flange is connected with speed reducer, motor flange is connected with motor, motor shaft is inserted in the motor shaft trepanning of input shaft, drive the speed reducer input gear by input shaft during machine operation and rotate in the direction of arrows, when the speed reducer parking, when motor quits work, the speed reducer input gear has a trend that oppositely reverses, but the existence of non-return device has prevented that this from oppositely reversing, and effectively guaranteed the operating accuracy of speed reducer.
Claims (3)
1. rigidity of gear reduction unit input flange structure with non-return device, comprise speed reducer flange, motor flange and input shaft, the speed reducer flange is fixedly connected with motor flange, input shaft passes the endoporus of speed reducer flange and motor flange, the endoporus of speed reducer flange and motor flange is respectively equipped with bearing input shaft is formed pivoting support, it is characterized in that: be provided with non-return device between speed reducer flange and the motor flange, the outer ring of non-return device is fixedly installed at the endoporus of speed reducer flange or motor flange, and the inner ring of non-return device is fixedly installed at the cylindrical of input shaft.
