Abstract

The utility model relates to a self-lubricating support device. In respect of support, an existing EBT actuator basically adopts a common lubricating method of shaft sleeve type or no lubrication that adopts the dry friction of copper sleeve and the lubricating method or no lubrication has the following defects: the EBT works in a severe and dusty environment and the dust enters the shaft sleeve easily, which accelerates abrasion and shortens the service life of a supporting point; the common supporting point of shaft sleeve type has complicated positioning and inconvenient processing; and the lubrication effect is not good. The self-lubricating support device is characterized in that: the self-lubricating support device consists of a rotating shaft, a self-lubricating bearing, a bearing upper cover and a bearing support; the rotating shaft is in interference fit with the self-lubricating bearing; the bearing upper cover and the bearing support are respectively arranged at both sides of the self-lubricating bearing. The self-lubricating support device has the advantages of effectively prolonged service life, good lubricating effect and simple processing.

Description

But a kind of bracing or strutting arrangement of self-lubricating

Technical field

The utility model belongs to the electric furnace steel making industry, but is specifically related to a kind of bracing or strutting arrangement of self-lubricating.

Technical background

Our now used EBT (eccentric bottom tapping) executing agency adopts the lubricating system of plain shaft shell type basically on supporting, perhaps not lubricated, adopt the copper sheathing dry friction, such lubricating system or lubricatedly have the residing work under bad environment of following shortcoming: EBT, dust is big, and dust enters the axle sleeve the inside easily and goes, wearing and tearing have been aggravated, reduce the life-span of the strong point, the location more complicated of the plain shaft shell type strong point, processing is inconvenient; Lubricated effect is not very desirable.

The utility model content

But the purpose of this utility model is to provide a kind of makes simply, the bracing or strutting arrangement of the self-lubricating of high lubricating effect.

The technical scheme of taking for the utility model that achieves the above object:

Special character of the present utility model is: but the bracing or strutting arrangement of described self-lubricating is made up of rotating shaft, self-lubricating bearing, bearing upper cover, bearing spider; Described rotating shaft and self-lubricating bearing interference fit, the both sides of self-lubricating bearing are provided with bearing upper cover, bearing spider respectively.

But the bracing or strutting arrangement of above-mentioned self-lubricating is arranged on EBT executing agency up and down on two strong points.

Advantage of the present utility model:

1, reduced the pollution of dust, effectively increased service life the strong point;

2, high lubricating effect is not used lubricating oil, the pollution of minimizing system self;

3, processing is simple, get on except hold-down ring on original basis, and axle sleeve, there do not have general expression to support to be complicated.

Description of drawings

Fig. 1 is the structural representation of EBT executing agency;

But Fig. 2 is the structural representation of the bracing or strutting arrangement 4 of self-lubricating in the EBT executing agency.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Referring to Fig. 1, Fig. 2, the utility model is made up of rotating shaft 5, self-lubricating bearing 6, bearing upper cover 7, bearing spider 8; Rotating shaft 5 and self-lubricating bearing 6 interference fit, the both sides of self-lubricating bearing 6 are provided with bearing upper cover 7, bearing spider 8 respectively.

But the bracing or strutting arrangement 4 of self-lubricating is arranged on EBT executing agency up and down on two strong points.

Connected mode:

At first be that rotating shaft 5 directly contacts with self-lubricating bearing 6, their interference fit, so that its location, with the bearing upper cover 7 and the support of bearing 8 self-lubricating bearing 6 is being wrapped in the middle of it, with bolt that it is dead, the limit of the rib of self-lubricating bearing 6 and bearing upper cover 7 and bearing spider 8 fixes, and makes it not have axial play, rotates more flexible.

Manner of execution:

When fluid pressure drive device 3 or manual whirligig 1 rotated rotating shaft 5, self-lubricating bearing 6 just made rotating shaft 5 rotate freely, and by position-sensing switch 2 location, and self-lubricating bearing 6 has the effect of self-lubricating, it is flexible to make it rotate.And 7 pairs of self-lubricating bearings of top bearing upper cover have protective effect, make that dust is difficult for entering, thereby have improved service life.

Such structure makes that rotating shaft processing is simple, does not re-use grease lubrication, has saved processing cost, has reduced pollution, has improved service life.

Claims (2)

1. But 1, a kind of bracing or strutting arrangement of self-lubricating is characterized in that: but the bracing or strutting arrangement of described self-lubricating (4) is made up of rotating shaft (5), self-lubricating bearing (6), bearing upper cover (7), bearing spider (8); Described rotating shaft (5) and self-lubricating bearing (6) interference fit, the both sides of self-lubricating bearing (6) are provided with bearing upper cover (7), bearing spider (8) respectively.
2. But 2, the bracing or strutting arrangement of a kind of self-lubricating according to claim 1 is characterized in that: but the bracing or strutting arrangement of described self-lubricating (4) is arranged on EBT executing agency up and down on two strong points.
