Usually, device for revolving and driving does not have auto-lock function, and especially, in the dead electricity situation, while running into as External Force Actings such as wind-force, the rotational position of device for revolving and driving can change, and when serious, also can cause device for revolving and driving to damage.Therefore, need a kind of device for revolving and driving with auto-lock function.
The model utility content
The purpose of this invention is to provide a kind of device for revolving and driving with electric losing self-locking function.
For realizing the object of the invention, this electric losing self-locking device for revolving and driving, comprise pedestal 1, pivoting support 3, worm screw 2, described pedestal 1 consists of axle housing 1.1 and seat ring 1.2 two-part, the shaft axis of the shaft axis of axle housing 1.1 and seat ring 1.2 is orthogonal in spatial position, described worm screw 2 is installed in the axle housing 1.1 of pedestal 1, described pivoting support 3 comprises inner ring 3.1, external toothing 3.2 and be embedded at inner ring 3.1 and external toothing 3.2 between ball, be provided with some installation screws on external toothing 3.2, inner ring 3.1 is fixed on the top of the seat ring 1.2 of pedestal 1, external toothing 3.2 and worm screw 2 engagements, also be provided with electromagnetic brake 7, described electromagnetic brake comprises support 7.3, described support 7.3 is connected and fixed with pedestal 1, coil 7.2 is installed in support 7.3, some springs 7.1, armature 7.4, friction disk 7.7, jointing plate 7.6, geared sleeve 7.5, spring 7.1 1 ends are fixed on support 7.3, the other end contacts with armature 7.4, worm screw 2 is provided with a worm screw extending portion 2.1, worm screw extending portion 2.1 is connected with geared sleeve 7.5, jointing plate 7.6 is provided with the tooth corresponding with geared sleeve 7.5 and is slidably connected with geared sleeve 7.5, jointing plate 7.6 is provided with friction disk 7.7, friction disk 7.7 joins with armature 7.4.
Further, coil 7.2 is the coil with yoke, to increase the magnetic energy of coil.
In the utility model, when controller is controlled the rotation of motor driving worm screw, controller provides power supply to coil simultaneously, attract armature movement after coil electricity, at this moment armature separates with friction disk, geared sleeve and worm screw are in free state, and the rotation of motor driven worm screw, worm screw driven pivoting support external toothing rotate; When controller is not controlled motor rotation, controller does not provide power supply to coil yet, and now, armature is pushed down to rub at the active force of spring and wiped Disk, thereby worm screw is pinned, and that is to say, when device for revolving and driving is not worked or during dead electricity, worm screw is in self-locking state.
The utility model is that worm screw has been set up electromagnetic brake, the technical problems such as the device for revolving and driving rotational position that has solved well device for revolving and driving and cause in the situation that dead electricity is easily affected by external force changes, reduced the spoilage of device for revolving and driving.
The utility model is simple in structure, easy to maintenance, reliable and stable, has good development prospect, and the present invention is applicable to the industries such as engineering machinery, building machinery, photovoltaic and uses.
It should be noted that, under the prerequisite that does not change principle of the present invention and design, can also make some changes or distortion to the present invention, this belongs to protection scope of the present invention equally.
