Abstract
The utility model discloses a cylindrical radial type magnetic force gap actuator which comprises an outer driving wheel and an inner driven wheel arranged coaxially but separated from each other. Sector-shaped permanent magnets are respectively mounted on part of the wheel bodies of the outer driving wheel and the inner driven wheel, and N/S poles of the sector-shaped permanent magnets are arranged alternatively along the radial direction of the driving/driven wheel. The cylindrical radial type magnetic force gap actuator carries out gap transmission in a magnetic force coupling driving manner, thereby effectively avoiding wearing due to purely-mechanical transmission among parts; and is simple in structure and stable in work.
Description
Technical field
The utility model relates to magnetic coupling technology field, is specifically related to a kind of cylinder radial magnetic gap driver.
Background technology
Batch (-type) driver is mainly used in counter, pipelining or some have in the professed machine of peculair motion requirement.Common are Geneva mechanism, incomplete gear mechanism etc.More than be contact mechanical transmission, inevitably can bring the lubricated maintenance work in mechanical wear and later stage, running inconvenience.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of by the mode of magnetic driver, can effectively avoid the effect between mechanical part, under the basis of contactless intermittently-driving, realize the cylinder radial magnetic gap driver of batch (-type) feeding transmission.
A kind of cylinder radial magnetic gap driver, comprise and be outer driver and the interior driven pulley that coaxial space arranges, on the local wheel body of described outer driver and interior driven pulley, fan-shaped permanent magnet is all installed, the N/S utmost point of described fan-shaped permanent magnet is along the radially arranged crosswise of driving wheel, driven pulley.
The central angle correspondence that the fan-shaped permanent magnet of described outer driver, interior driven pulley forms is identical.
The fan-shaped permanent magnet of described outer driver, interior driven pulley adopts identical hard magnetic material.
The mode that the utility model drives by magnetic couple is carried out intermittently-driving, has effectively avoided wearing and tearing that the transmission of the Purely mechanical between parts brings etc., simple structure, working stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for the present invention is described but not for limiting the scope of the invention.
Embodiment 1
Referring to Fig. 1, a kind of cylinder radial magnetic gap driver that the utility model provides, comprise and be outer driver 1 and the interior driven pulley 2 that coaxial space arranges, fan-shaped permanent magnet 3 is all installed on the local wheel body of described outer driver 1 and interior driven pulley 2, and the N/S utmost point of described fan-shaped permanent magnet 3 is along the radially arranged crosswise of driving wheel, driven pulley.
The central angle alpha correspondence that the fan-shaped permanent magnet 3 of described outer driver 1, interior driven pulley 2 forms is identical.
The fan-shaped permanent magnet 3 of described outer driver 1, interior driven pulley 2 adopts identical hard magnetic material.
When outer driver 1 rotates, when if the position of rotation makes the fan-shaped permanent magnet 3 of outer driver 1 relative with the fan-shaped permanent magnet 3 of interior driven pulley 2, driven pulley 2 rotations in driving under the effect of magnetic couple so, otherwise not at once, interior driven pulley 2 will be without magnetic drive, slack, thereby realize when outer driver 1 rotates continuously, interior driven pulley 2 obtains intermittent movement.
Claims (3)
1. a cylinder radial magnetic gap driver, it is characterized in that: comprise and be outer driver and the interior driven pulley that coaxial space arranges, on the local wheel body of described outer driver and interior driven pulley, fan-shaped permanent magnet is all installed, the N/S utmost point of described fan-shaped permanent magnet is along the radially arranged crosswise of driving wheel, driven pulley.
2. a kind of cylinder radial magnetic gap driver according to claim 1, is characterized in that: the central angle correspondence that the fan-shaped permanent magnet of described outer driver, interior driven pulley forms is identical.
3. a kind of cylinder radial magnetic gap driver according to claim 1, is characterized in that: the fan-shaped permanent magnet of described outer driver, interior driven pulley adopts identical hard magnetic material.
