Description
Technical Field
The invention relates to the technical field of speed reducers, in particular to a magnetic sealing device of a speed reducer.
Background
The sealing is a problem that must be solved in the reduction gear use, and the reduction gear sealing device commonly used has a lot of kinds, and sealed effect also is diverse, no matter is sealed by contact or non-contact, all hardly accomplishes completely sealed.
Disclosure of Invention
The invention aims to provide a magnetic sealing device for a speed reducer, which solves the problem of poor sealing effect of the speed reducer.
In order to achieve the purpose, the invention adopts the following technical scheme:
a magnetic sealing device for speed reducer comprises
The mounting seat is detachably mounted on a shell of the speed reducer and is loosely sleeved outside a rotating shaft of the speed reducer;
the static ring is arranged in the mounting seat and can be sleeved on the rotating shaft in a sliding manner;
the rotating shaft is fixedly sleeved with the rotating ring, a first side face of the rotating ring, which is opposite to the outer side face of the static ring, is provided with a containing groove, and the containing groove, the side face of the rotating shaft and the outer side face of the static ring form an installation cavity;
the magnetic element is fixedly arranged in the accommodating groove and filled in the mounting cavity, and the magnetic element follows the moving ring and rotates relative to the static ring.
Furthermore, the sealing device also comprises two O-shaped rings which are respectively arranged between the static ring and the mounting seat and between the movable ring and the rotating shaft.
Further, the sealing device also comprises a clamping ring, wherein the clamping ring is arranged in the mounting seat and limits the position of the inner side face of the static ring.
Has the advantages that:
the traditional sealing mode is changed, and the magnetic element is sealed by utilizing the magnetic force adsorption characteristic. The magnetic element can still tightly attach to the static ring to realize complete sealing while rotating relative to the static ring. When quiet ring and mount pad hole, rotating ring and axle interference are connected, the outside of quiet ring and the inside of rotating ring establish the recess and be used for installing O shape circle, better assurance rotating ring and axle, quiet ring and the sealed between the mount pad.
Drawings
FIG. 1 is a schematic representation of the present invention.
The reference numbers in the figures are:
1: a housing, 2: connecting screw, 3: mount pad, 4: stationary ring, 5: magnetic element, 6: rotating ring, 7: a rotating shaft and 8: o-ring, 9: and a collar.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
referring to the drawings, the invention provides a magnetic sealing device for a speed reducer, which comprises
The mounting seat 3 can be detachably mounted on the shell 1 of the speed reducer 3, and the loose sleeve is arranged outside the rotating shaft 7 of the speed reducer 1.
The static ring 4 is arranged in the mounting seat 3 and is sleeved on the rotating shaft 7 in a sliding manner;
the rotating shaft 7 is fixedly sleeved with the rotating ring 6, the first side face of the rotating ring 6, which is opposite to the outer side face of the static ring 4, is provided with an accommodating groove, and the accommodating groove, the side face of the rotating shaft 7 and the outer side face of the static ring 4 form an installation cavity;
and the magnetic element 5 is fixedly arranged in the accommodating groove and is filled with the mounting cavity, and the magnetic element 5 follows the movable ring 6 and rotates relative to the fixed ring 4.
