Abstract
The utility model discloses a primary pivot armature structure with superstrong wear resistance, it comprises supported hole, axle sleeve, the primary pivot of armature, the utility model discloses an add the axle sleeve in the primary pivot of armature, make not produce between the primary pivot of armature and the axle sleeve and rotate, prevent effectively that the primary pivot of armature from leading to relay complete machine to become invalid because of frictional force is too big.
Description
One, technical field
The utility model relates to a kind of primary rotating shaft armature with superpower wear-resistant performance, belongs to the electromagnetic relay field.
Two, background technology
Electromagnetic relay is made up of internal structure and sealing cover.
Internal structure is by contact system, electromagnetic system and be connected to prop up and be configured to.Electromagnetic system is the mechanism that electric energy is transformed mechanical energy, comprises coil, work magnetic loop and mechanical energy actuator;
The work magnetic loop of electromagnetic system is made up of iron core, yoke, pole shoe and armature, and armature produces motion under the effect of the fixedly magnetic loop that iron core, yoke, pole shoe are formed.The pivot of armature motion has two kinds of versions, wherein a kind of is primary rotating shaft on armature, it generally is acquisition by car system, this kind pivot structure is comparatively simple, the processing technology maturation, use comparatively extensively, another kind of version is the regeneration rotating shaft, generally is by welding or riveted way armature and special rotating shaft formation to be rigidly connected.
In the electromagnetic relay of large volume, when armature rotates, its primary rotating shaft is to rotate by the supported hole that is fixed on the fixed head on other parts, when primary rotating shaft rotates in supported hole, because the electromagnetic attraction of electromagnetic system is relatively large, the pressure that acts on the primary rotating shaft of armature surface also can increase, between primary rotating shaft and supported hole, produce frictional force easily, and the size of frictional force is subjected to the residing influence towards the environment that shakes of relay bigger, when relay is in when dashing in the environment that shakes, the frictional force between primary rotating shaft and the supported hole will increase to tens of times under the normal condition.Primary rotating shaft surface will produce serious wearing and tearing, finally causes the disabler of armature.
Three, summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, and a kind of primary rotating shaft armature structure with superpower wear-resistant performance of setting up shaft sleeve parts in primary rotating shaft is provided.
A kind of primary rotating shaft armature structure of the present utility model with superpower wear-resistant performance, it is made up of supported hole, axle sleeve, the primary rotating shaft of armature, in the primary rotating shaft of armature, be provided with axle sleeve, outside axle sleeve, be provided with supported hole, in the primary rotating shaft of armature, be provided with the axle sleeve of tubular structure, adopt interference fit between the primary rotating shaft of sleeve lining and armature, adopt matched in clearance between sleeve outer surface and the supported hole.
Adopt the beneficial effect of technique scheme to be:, to prevent that effectively primary rotating shaft from causing the relay complete machine to lose efficacy because of frictional force is excessive owing to do not rotate between primary rotating shaft of armature and the axle sleeve.
Four, description of drawings
Fig. 1 is a kind of structural representation with primary rotating shaft armature structure of superpower wear-resistant performance of the present utility model.
Among the figure: 1-supported hole, 2-axle sleeve, the primary rotating shaft of 3-armature.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of primary rotating shaft armature structure of the present utility model with superpower wear-resistant performance, it is by supported hole 1, axle sleeve 2, the primary rotating shaft 3 of armature is formed, 3 are provided with axle sleeve 2 in the primary rotating shaft of armature, outside axle sleeve 2, be provided with supported hole 1, axle sleeve 2 adopts tubular structure, adopt interference fit between the primary rotating shaft 3 of axle sleeve 2 inwalls and armature, its purpose is to guarantee the friction that do not rotate between primary rotating shaft 3 of armature and the axle sleeve 2, avoid the primary rotating shaft of armature 3 surfaces to produce wearing and tearing because of pivoting friction, the tube wall of axle sleeve 2 generally adopts the above thickness of 0.3mm, concrete condition can adopt matched in clearance between axle sleeve 2 outer surfaces and the supported hole 1 according to the diameter decision of the primary rotating shaft 3 of armature.Owing to need carry out rotatablely moving each other between axle sleeve 2 outer surfaces and the supported hole 1, so axle sleeve 2 outer surfaces and supported hole 1 inner surface should have certain fineness.
Claims (2)
1, a kind of primary rotating shaft armature structure with superpower wear-resistant performance, it is made up of supported hole (1), axle sleeve (2), the primary rotating shaft of armature (3), it is characterized in that: be provided with axle sleeve (2) in the primary rotating shaft of armature (3), the outer supported hole (1) that is provided with of axle sleeve (2).
2, a kind of primary rotating shaft armature structure as claimed in claim 1 with superpower wear-resistant performance, it is characterized in that: axle sleeve (2) is a tubular structure, adopt interference fit between axle sleeve (2) inwall and the primary rotating shaft of armature (3), adopt matched in clearance between axle sleeve (2) outer surface and the supported hole (1).
