Abstract

The utility model discloses an air-cooled self-lubricating sliding bearing which comprises a self-lubricating sliding bearing body and a fan. The fan is fixedly disposed on a rotating shaft of the sliding bearing body and is close to the self-lubricating sliding bearing body. The fan is installed on the rotating shaft of the sliding bearing body so that air movement on the outer surface of a bearing seat of the self-lubricating sliding bearing body is accelerated and heat dissipation speed of the surface of the bearing seat is increased. Double oil rings are adopted in the air-cooled self-lubricating sliding bearing, and consequently the air-cooled self-lubricating sliding bearing solves the problem that damages to a bearing bush due to the fact that carried oil is insufficient when the air-cooled self-lubricating sliding bearing operates at high speed. Therefore, allowable load and rotating speed of the air-cooled self-lubricating sliding bearing can be increased.

Description

A kind of air-cooled self-lubricating plain bearing

Technical field

The utility model relates to a kind of sliding bearing, particularly a kind of air-cooled self-lubricating plain bearing.

Background technique

Self-lubricating plain bearing is meant the sliding bearing of no outer loop oil supply system.Traditional self-lubricating plain bearing adopts single oil ring to give the bearing shell fuel feeding usually, and the heat that relies on the diffusing bearing running in bearing support surface when operation, to be produced reaches thermal equilibrium.Because the bearing support surface radiating is limited; And the heat that the bearing operation time is produced depends primarily on the rotating speed and the load of bearing; Therefore traditional self-lubricating plain bearing only is applicable to the operating mode of the slow-speed of revolution, underload; And it adopts the fuel feeding of single oil ring when running up, and it is not enough and cause the phenomenon of damage of bearings that fuel feeding appears in the bearing lubrication meeting.

The model utility content

In order to solve the problems of the technologies described above, the utility model provides a kind of air-cooled self-lubricating plain bearing with higher allowable load and rotating speed.

The technological scheme that the utility model adopts is: comprise self-lubricating plain bearing and fan, fan is packed in the rotating shaft of self-lubricating plain bearing supporting, near self-lubricating plain bearing.

In the above-mentioned air-cooled self-lubricating plain bearing, said self-lubricating plain bearing is provided with two oil rings.

In the above-mentioned air-cooled self-lubricating plain bearing, fan is packed in the rotating shaft of self-lubricating plain bearing supporting through key and locking device.

In the above-mentioned air-cooled self-lubricating plain bearing, also comprise support, place the fan outside, be installed on the bearing support of self-lubricating plain bearing.

The beneficial effect of the utility model is: the utility model is equipped with fan in the rotating shaft of self-lubricating plain bearing supporting, quickens the bearing support outer surface air flow of self-lubricating plain bearing, has accelerated bearing support surface radiating speed; Self-lubricating plain bearing adopts two oil rings in the utility model, owing to the problem of the bearing shell damage of being with shortage of oil to cause, therefore can improve the allowable load and the rotating speed of self-lubricating plain bearing when having solved the self-lubricating plain bearing high speed operation.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, the utility model comprises key 1, locking device 3, fan 4, support 5 and self-lubricating plain bearing 6, and fan 4 is packed in the rotating shaft 2 of self-lubricating plain bearing 6 supportings, near self-lubricating plain bearing 6 through key 1 and compression device 3; Support 5 places fan 4 outsides, is fixed on the bearing support 62 of self-lubricating plain bearing 6, and self-lubricating plain bearing 6 is provided with two oil rings 61.

When host-initiated, rotating shaft 2 rotations, two oil rings 61 hang in the main frame rotating shaft 2, and oil ring 61 rotations also are with oil in bearing support 62, supply bearing shell 63 lubricated uses; Fan 4 is given the blowing of bearing support 62 outer surfaces with rotating shaft 2 rotations, quickens bearing support surface air flow, makes in 62 unit time of the bearing support unit area and distributes more heats, and support 5 plays the safety protection effect.
