Abstract
The invention discloses a medical DR (direct digital flat plate X-ray radiograph system) lifting arm driving mechanism, which comprises a fixing base (6), a driven gear (2), a duplex gear (3), a transmission gear group (4) and a motor (5), wherein the driven gear (2) is fixedly connected with a lifting arm (1), a bevel gear is arranged on an output shaft of the motor (5), and is engaged with the transmission gear group (4), the transmission gear group (4) is also engaged with one linked gear of the duplex gear (3), the driven gear (2) adopts an inner gear with inner teeth, and in addition, inner teeth of the driven gear (2) are engaged with the other linked gear of the duplex gear (3). The medical DR lifting arm driving mechanism has the advantages that the structure is simple, the design is reasonable, the work is reliable and stable, the integral space occupied by an electric lifting arm driving mechanism is greatly reduced, and in addition, the driving energy consumption is reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly one medical DR(Direct Digital flat panel X-ray imaging system) lift arm driving mechanism.
Background technology
Along with developing rapidly and growth in the living standard of science and technology, the idea that the instructions for use of people to equipment is not only confined to " can with just ", people are more and more inclined to and pursue environmental protection, durable and attractive in appearance.Along with improving constantly of medical level, electronic act arm is medically being used widely.
Existing electronic act arm all with electric pushrod, sprocket wheel, Timing Belt etc. for drive, but take electric pushrod, sprocket wheel, Timing Belt etc. as the electronic act arm driven, not only energy consumption is comparatively large, and shared space is also larger, consider that there is certain defect from energy-conservation and outward appearance.
Summary of the invention
The object of the invention is to the some shortcomings for existing electronic act arm driving mechanism, provide and a kind ofly adopt the medical DR(Direct Digital flat panel X-ray imaging system of internal gear engaged transmission form) lift arm driving mechanism.This driving mechanism structure is simple, reasonable in design, reliable operation, stable, greatly reduces the overall space that electronic act arm driving mechanism takies, and reduces it and drive energy consumption.
To achieve these goals, the present invention is by the following technical solutions:
A kind of medical DR lifts arm driving mechanism, the driven gear, duplicate gear, driving gear set and the motor that comprise fixed pedestal, are fixedly connected with act arm, and the output shaft of described motor is provided with bevel gear, and bevel gear is meshed with driving gear set; Described driving gear set is also meshed with the wherein gear in duplicate gear; Wherein: described driven gear adopts the internal gear being provided with internal tooth, and the internal tooth of driven gear and another in duplicate gear join gear is meshed.
Driving mechanism of the present invention, is placed in the inner side of driven gear by duplicate gear, make compact being installed together of each drive disk assembly in driving mechanism, reduce the space that driving mechanism takies, allow driving mechanism can design more attractive in appearance; Each gear is meshed, and power transmits successively, works more reliable and more stable.During electric motor starting, drive driving gear set to rotate, the driving gear set of rotation drives duplicate gear to rotate, and duplicate gear drives driven gear to rotate around gear shaft again, thus arm lifting is lifted in drive.
Further illustrate as of the present invention, above-described driven gear adopts in fan-shaped internal gear, and fan angle is 90 ゜ ~ 190 ゜.Lift arm to be fixedly connected on fan-shaped radius edge, be conveniently welded and fixed and lift the carrying out of the lifting action of arm.
Further illustrate as of the present invention, above-described driven gear, duplicate gear, driving gear set are arranged on fixed pedestal respectively by gear shaft and rotary sleeve.
Compared with prior art, the beneficial effect that possesses of the present invention:
Structure is simple, take up room little, act arm lifting action stable and reliable operation.Present invention employs the driven gear that internal tooth is set, and duplicate gear is arranged on the inner side of driven gear, greatly reduce the space taken needed for driving mechanism, can allow the better of the appearance design of driving mechanism.The mode that the present invention adopts each gear to be meshed, power transmits successively, work more reliable and more stable, and energy consumption is also lower.

Fig. 2 is the partial structurtes schematic diagram of one embodiment of the invention.
In figure: 1. semi-girder, 2. driven gear, 3. duplicate gear, 4. driving gear set, 5. motor, 6. fixed pedestal.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment:
As shown in Figure 1-2, a kind of medical DR lifts arm driving mechanism, the driven gear 2, duplicate gear 3, driving gear set 4 and the motor 5 that comprise fixed pedestal 6, are fixedly connected with act arm 1, the output shaft of described motor 5 is provided with bevel gear, and bevel gear is meshed with driving gear set 4; Described driving gear set 4 is also meshed with the wherein gear in duplicate gear 3; Wherein, described driven gear 2 adopts the internal gear being provided with internal tooth, and the internal tooth of driven gear 2 and another in duplicate gear 3 join gear is meshed.
Described driven gear 2 adopts in fan-shaped internal gear, and fan angle is 170 ゜.Described driven gear 2, duplicate gear 3, driving gear set 4 are arranged on fixed pedestal 6 respectively by gear shaft and rotary sleeve.
The driving mechanism structure of the present embodiment is simple, take up room little, act arm lifting action stable and reliable operation.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is only: the fan angle of described driven gear 2 is 90 °.
Embodiment 3:
The difference of the present embodiment and embodiment 1 is only: the fan angle of described driven gear 2 is 190 °.
Embodiment 4:
The difference of the present embodiment and embodiment 1 is only: the fan angle of described driven gear 2 is 120 °.
