Description
Technical Field
The utility model belongs to the technical field of permanent magnet coupling, specifically speaking especially relates to an online adjustment mechanism of permanent magnet coupling.
Background
The permanent magnet coupling is a novel coupling for connecting a prime motor and a working machine by the magnetic force of a permanent magnet. The permanent magnet coupling does not need direct mechanical connection, but utilizes the interaction between rare earth permanent magnets and utilizes the characteristic that a magnetic field can penetrate a certain space distance and a material to transmit mechanical energy. The leakage problem of dynamic seal in some mechanical devices is thoroughly solved by the magnetic coupling. The product is widely applied to sealed transmission machinery in the industries of chemical engineering, electroplating, papermaking, pharmacy, food, vacuum and the like.
The axial direction of a magnetic disk of the existing permanent magnet coupling is mostly not adjustable.
Disclosure of Invention
In order to solve the problem, the utility model discloses a permanent magnet shaft coupling online adjustment mechanism.
The utility model discloses a realize through following technical scheme:
the utility model provides a permanent magnet coupling online adjustment mechanism, includes transmission shaft, worm gear case part, slip overcoat, slip endotheca, support, worm gear case part and support are fixed on the ground, worm gear case part includes worm, worm wheel, the transmission shaft outside is connected with the load flange, the load flange through the spline with the slip endotheca is connected, the slip endotheca is connected with the permanent magnetism dish, the slip endotheca through the bearing with the slip overcoat rotates to be connected, the excircle of slip overcoat is provided with trapezoidal thread, the slip overcoat pass through trapezoidal thread with the inboard screw thread of worm wheel closes soon.
And a conductor steel disc is arranged close to the permanent magnetic disc and connected with the sliding inner sleeve.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses rotate the worm when the operation, it is rotatory to drive the worm wheel, can drive slip overcoat and the slip endotheca and the permanent magnetism dish axial displacement that link to each other with it, realizes regulatory function.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a drive shaft; 2. a worm gear case member; 2-1, a worm; 2-2, a worm gear; 3. sliding the outer sleeve; 4. Sliding the inner sleeve; 5. a support; 6. a load flange; 7. a permanent magnet disk; 8. a conductor steel disc.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 of the attached drawings of the specification, an online adjusting mechanism for a permanent magnet coupler comprises a transmission shaft 1, a worm gear box component 2, a sliding outer sleeve 3, a sliding inner sleeve 4 and a support 5, wherein the worm gear box component 2 and the support 5 are fixed on a foundation, the worm gear box component 2 comprises a worm 2-1 and a worm gear 2-2, a load flange 6 is connected to the outer side of the transmission shaft 1, the load flange 6 is connected with the sliding inner sleeve 4 through a spline, the sliding inner sleeve 4 is connected with a permanent magnet disc 7, the sliding inner sleeve 4 is rotatably connected with the sliding outer sleeve 3 through a bearing, trapezoidal threads are arranged on the outer circle of the sliding outer sleeve 3, and the sliding outer sleeve 3 is screwed with the inner side threads of the worm gear 2-2 through the trapezoidal threads.
Preferably, a conductor steel disc 8 is arranged close to the permanent magnet disc 7, and the conductor steel disc 8 is connected with the sliding inner sleeve 4.
Example (b):
an online adjusting mechanism for a permanent magnet coupler comprises a transmission shaft 1, a worm gear box component 2, a sliding outer sleeve 3, a sliding inner sleeve 4 and a support 5, wherein the worm gear box component 2 and the support 5 are fixed on a foundation, the worm gear box component 2 comprises a worm 2-1 and a worm wheel 2-2, the outer side of the transmission shaft 1 is connected with a load flange 6, the load flange 6 is connected with the sliding inner sleeve 4 through a spline, the sliding inner sleeve 4 is connected with a permanent magnet disc 7, the sliding inner sleeve 4 is rotatably connected with the sliding outer sleeve 3 through a bearing, the outer circle of the sliding outer sleeve 3 is provided with trapezoidal threads, and the sliding outer sleeve 3 is screwed with the inner side threads of the worm.
When in use, the sliding inner sleeve 4 is connected with the permanent magnetic disk 7 and connected with the load flange 6 through a spline, so that the sliding inner sleeve can synchronously rotate and can relatively slide along the axial direction; meanwhile, the sliding outer sleeve 3 is connected with the sliding inner sleeve 4 through a bearing, and can rotate relatively but cannot move relatively along the axial direction. When the device runs, the worm 2-1 is rotated to drive the worm wheel 2-2 to rotate, and the sliding outer sleeve 3, the sliding inner sleeve 4 connected with the sliding outer sleeve and the permanent magnet disc 7 are driven to axially move, so that the adjusting function is realized.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
