Specific embodiment
With reference to the accompanying drawing by specific embodiment, further a specific embodiment of the invention work is retouched in detail
It states.
The present invention loses for the engineering reverse self-locking that typical Worm and worm-wheel gearing occurs in vibration test in practice
Effect problem proposes a kind of magnetic force moment device.
Magnetic force moment device as shown in Figure 1, being made of fixed magnet-wheel 1 and movable magnet-wheel 2, axially coaxially put by the two, and two
End face is opposed.Magnet-wheel composition as shown in Figures 2 and 3, is made of permanent magnet 3, hexahedron 4 and supporter 5, and 3N grades and S grades of permanent magnet
It is radially distributed, it is divided into the direction N-S and the direction S-N and circumferentially-spaced uniformly distributed in magnet-wheel.Fixed magnet-wheel 1 and movable magnet-wheel 2
On 3 quantity of permanent magnet it is identical.
The installation of magnetic force moment device is as shown in Figure 4.Magnetic force moment device apply in worm gear mechanism transmission, wherein worm screw
7 be input terminal, and it is a force amplificatory structure that worm gear 9, which is output end,.Fixed magnet-wheel 1 is mounted on end cap 8, and position fixation can not live
It is dynamic；Movable magnet-wheel 2 is mounted on worm screw 7, can be rotated and be rotated with worm screw 7.Fixed magnet-wheel 1 and movable magnet-wheel 2 are axial same
Axis is put, and the direction the N-S permanent magnet on the former and the direction the S-N permanent magnet on the latter generate suction relatively, and opposite with the latter
The direction the N-S permanent magnet of permanent magnet two sides generates repulsion, and the magnetic torque that suction and repulsion collective effect generate hinders the two
It relatively rotates.When dynamic input, in power transmission to worm screw 7, worm screw 7 overcomes between fixed magnet-wheel 1 and movable magnet-wheel 2
Magnetic torque rotates, and transmits power on worm gear 9.When unpowered input, fixed magnet-wheel 1 and movable magnet-wheel 2 pass through
Magnetic torque constraint does not relatively rotate.When vibration, which can keep worm and gear that relative motion does not occur, thus real
It is existing self-locking.Axial gap between fixed magnet-wheel 1 and movable magnet-wheel 2 can be adjusted by adjusting gasket 5, obtain suitable magnetic
Torque, to meet: 1) when needing power transmission, which will not generate excessive power consumption；2) when needing self-locking, the magnetic
Torque can guarantee effectively self-locking.
Magnetic force moment device of the invention has the advantages that 1) structure is simple, and installation space is small, good manufacturability；2) non-to connect
The magnetic force principle of moment of touch compares contact, and performance is stablized, high reliablity；3) magnetic wheel permament magnet iron is using magnetic symmetrical row of interlocking
Cloth avoids unbalance stress, causes noise；4) it is mounted on the front end of force amplificatory structure, Yi Shixian small to magnetic torque quantity demand.
Experiment proves that magnetic force moment device works well, it can solve what worm and gear reverse self-locking under vibration condition failed
Problem.The moment values of magnetic torque are smaller simultaneously, and the extracurrent generated to product normal operation is about 0.15A, the normal work of product
Make current requirements no more than 5A, general control is in 3~4A, it is known that increased electric current influences product overall power little.
