Axle Bearing Sealing Structure

Technical Field

The utility model relates to the technical field of axle bearings, and particularly relates to an axle bearing sealing structure.

Background Technology

An axle is an important component in automobile manufacturing. It is connected to the frame through the suspension system, and its primary function is to bear vehicle loads. It also provides steering and driving functions. Due to complex road conditions, the axle must possess sufficient rigidity and strength to maintain normal vehicle operation.

Existing axle bearings lack:

an effective sealing mechanism for the internal bearings,

a fixing mechanism to prevent deformation of the sealing ring,

and an automatic lubrication mechanism for lubricating the bearings through rolling balls during rotation.

Therefore, it is necessary to provide an axle bearing sealing structure to solve the above problems.

Utility Model Content

The utility model provides an axle bearing sealing structure, which solves the problems that existing axle bearings:

lack an internal bearing sealing mechanism,

lack a fixing mechanism for preventing deformation of the sealing ring,

and lack an automatic lubrication mechanism for lubricating the bearing through rolling balls during operation.

To achieve the above objectives, the utility model provides an axle bearing sealing structure comprising:

a body,

an inner bearing installed inside the body,

a sealing mechanism connected to the inner wall of the body,

and a lubrication mechanism installed inside the inner bearing.

Preferred Embodiments

Sealing Mechanism

The sealing mechanism includes:

a sealing ring,

a movable shaft mounted on the outer side of the sealing ring,

a rotating plate connected to the movable shaft,

a connecting block fixed on one side of the sealing ring,

a slider fixed at the top end of the connecting block,

and a sliding groove slidably connected with the slider.

Rotating Structure

The rotating plate forms a rotating structure with the body through the movable shaft, and the horizontal axis of the movable shaft coincides with the horizontal axis of the rotating plate.

Sliding Structure

The connecting block forms a sliding structure with the body through the slider and the sliding groove, and the body is integrally formed with the connecting block through slotting.

Lubrication Mechanism

The lubrication mechanism includes:

a first absorbent cotton layer,

rolling balls movably connected to the bottom end of the first absorbent cotton layer,

and a second absorbent cotton layer installed beneath the rolling balls.

The first absorbent cotton layer and the second absorbent cotton layer are symmetrical about the horizontal axis of the rolling balls, and their center axes coincide.

Beneficial Effects

Compared with the prior art, the utility model provides the following advantages:

1. Improved Sealing Performance

Under the action of the sealing mechanism:

the connecting block slides within the body through the slider and sliding groove,

thereby fixing the sealing ring onto the inner wall of the body,

allowing the sealing ring to seal the bearing effectively,

preventing dust intrusion and maintaining bearing performance.

By rotating the rotating plate:

the rotating plate moves through the movable shaft,

pressing tightly against the top of the sealing ring,

thereby preventing deformation of the sealing ring under pressure,

and ensuring reliable sealing performance.

2. Excellent Sealing Ring Material Properties

The sealing ring is made of fluororubber.

Compared with silicone rubber, fluororubber has:

extremely high temperature resistance,

excellent weather resistance,

ozone resistance,

chemical resistance,

and strong resistance to oils and solvents, especially:

acids,

aliphatic hydrocarbons,

aromatic hydrocarbons,

and animal and vegetable oils.

Therefore, it is highly suitable for axle sealing applications.

In addition, it features:

strong corrosion resistance,

resistance to aging,

long service life,

good wear resistance,

and partial self-compensation after wear.

3. Automatic Lubrication Function

Under the action of the lubrication mechanism:

rotation of the inner bearing drives the rolling balls to rotate,

allowing the rolling balls to move between the inner bearing and the body.

Since the first and second absorbent cotton layers remain stationary:

the rolling balls rotate between them,

and the lubricating oil absorbed in the cotton layers lubricates the outer surfaces of the rolling balls.

This:

does not affect rolling performance,

improves rotational flexibility between the body and the inner bearing,

enhances bearing efficiency,

and extends bearing service life.

Working Principle

When the motor operates:

the connecting block slides inside the body through the slider and sliding groove,

thereby fixing the sealing ring onto the inner wall of the body,

enabling the sealing ring to seal the bearing and prevent dust intrusion.

By rotating the rotating plate:

the rotating plate pivots through the movable shaft,

tightly pressing against the sealing ring,

preventing deformation and ensuring sealing effectiveness.

The fluororubber sealing ring:

possesses excellent weather resistance, ozone resistance, and chemical resistance,

is highly resistant to oils and solvents,

and provides strong corrosion resistance, anti-aging performance, long service life, and wear resistance.

When the inner bearing rotates:

the rolling balls rotate correspondingly,

moving between the inner bearing and the body.

The stationary absorbent cotton layers continuously lubricate the rolling balls with absorbed lubricating oil, thereby:

improving rotational smoothness,

increasing working efficiency,

and prolonging service life.

Thus, the operation of the device is completed.
