Abstract
A transverse arm rotation driving mechanism for a medical X-ray machine comprises a motor, a worm gear, a worm, a worm support, a gear and a mounting plate. The motor is mounted on the mounting plate to drive the gear in rotation, the gear drives the worm then, the worm mounted on the support through a tapered roller bearing drives the worm gear, and finally the worm gear drives a transverse arm to rotate. The transverse arm rotation driving mechanism for a medical X-ray machine has the advantages of low noise, small acting force between the worm gear and the worm, resistance to structural deformation, long service life, low cost, convenience in maintenance and the like, and is widely applicable to rotation driving of the transverse arm of the medical X-ray machine.
Description
Technical field
This utility model relates to the driving mechanism that a kind of medical x-ray machine transverse arm rotates, and belongs to medical instruments field.
Background technology
Problems such as the driving of medical x-ray machine transverse arm rotation exists agency cost high mostly at present, installs and the processing technique difficulty, and service life is low, and noise is big.The reliability of armarium and low noise are the key factors of valuator device, and therefore reducing the armarium noise is to need the urgent problem that solves with improving the armarium reliability.
The utility model content
The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, the driving mechanism that provides a kind of new medical X-ray machine transverse arm to rotate.
In order to achieve the above object, this utility model adopts following technical scheme:
The driving mechanism that a kind of medical x-ray machine transverse arm rotates comprises motor, worm gear, worm screw, worm screw supporting seat, driving gear, driven gear and installing plate, and said motor is installed on the installing plate; The motor shaft of said motor connects driving gear; Said driving gear connects driven gear, and said driven gear connects worm screw one end, and said worm screw is installed on the dead eye of worm screw supporting seat through taper roll bearing; The bearing two ends have end cap mutually; Said worm screw connects worm gear, and described worm gear is installed on Rotational Cylindrical, and said Rotational Cylindrical also is provided with transverse arm.
As preferably, said worm screw position is higher than worm gear.
As preferably, said motor and worm screw average level are provided with.
As preferably, said worm screw two ends are installed on the worm screw supporting seat through taper roll bearing, and the worm screw supporting seat is fixed on the installing plate.
As preferably, said motor is connected with the installing plate bolt.
This utility model makes it compared with prior art owing to adopted above technical scheme, has the following advantages and characteristics:
1. adopt the mode of putting on the worm screw, greatly reduce the active force between worm gear and the worm screw, reduced the wearing and tearing between the worm and gear, reduced heating and noise between worm and gear, prolonged the service life of worm and gear, improved the operational reliability of equipment.
2. worm and gear transmission gear ratio is big, and under the situation of same gear ratio, volume is littler.
3. adopt this kind of drive, drive mechanism is simple, is easy to processing, and with low cost, installation and maintenance are simple.
Description of drawings
Accompanying drawing is used to provide the further understanding to this utility model, and constitutes the part of description, is used to explain this utility model with the embodiment of this utility model, does not constitute the restriction to this utility model.In the accompanying drawings:

The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains this utility model, and be not used in qualification this utility model this utility model.
As depicted in figs. 1 and 2; The driving mechanism that a kind of medical x-ray machine transverse arm rotates; Comprise motor 2, worm gear 8, worm screw 7, worm screw supporting seat 4, driving gear 3, driven gear 9 and installing plate 1, taper roll bearing 6 is installed at worm screw 7 two ends, is installed in then in the dead eye of worm screw supporting seat 4; Withstand with end cap 5 at the bearing two ends, and the worm screw in the vertical direction is positioned at the top of worm gear.Worm gear 8 is installed on the Rotational Cylindrical 12, and transverse arm is installed on the Rotational Cylindrical 12, so transverse arm 11 is by worm gear drives and rotation.Motor 2 is installed on the installing plate 1, under the drive of motor 2, and driving gear 3, driven gear 9, worm screw 7 transmission successively, worm screw 7 drives worm gear 8, drives transverse arm 11 through worm gear 8 then and rotates.
1. adopt the mode of putting on the worm screw, greatly reduce the active force between worm gear 8 and the worm screw 7, reduced the wearing and tearing between the worm and gear, reduced heating and noise between worm and gear, prolonged the service life of worm and gear, improved the operational reliability of equipment.
2. worm and gear transmission gear ratio is big, and under the situation of same gear ratio, volume is littler.
3. adopt this kind of drive, drive mechanism is simple, is easy to processing, and with low cost, installation and maintenance are simple.
What should explain at last is: the above is merely the embodiment of explanation this utility model; Be not limited to this utility model; For a person skilled in the art; All within the spirit and principle of this utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
