Abstract

The invention provides an adhesion-resistant and long-life truck hub bearing unit. The truck hub bearing unit comprises two bearings, a flange plate and a clamping ring, wherein a small hole is formed in the flange plate; sealing devices are additionally arranged in the middles of outer rings of the two bearings; each sealing device consists of a sealing elastic piece and a sealing sleeve; a small hole is formed in each sealing sleeve and is communicated with the small hole formed in the flange plate. In the running process of a vehicle, the internal temperature of hub bearings rises, the pressure increases, the sealing elastic pieces are pushed to move upwards, and gas is discharged through the small hole in the flange plate, so that the internal temperature of the bearings drops, and the pressure decreases. Through the cyclic operation, in the running process of the vehicle, the temperature and the pressure are limited in a certain range, the phenomena of adhesion of a rolling body inside each bearing to a sleeve ring at high temperature and failure in bearing sealing caused by high internal temperature and large pressure of the bearings are prevented, and the bearings are long in life, and high in safety and reliability.

Description

Anti-bonding long-life truck hub bearing unit

Technical field

The present invention relates to a kind of truck hub bearing unit, especially a kind of anti-bonding long-life truck hub bearing unit.

Background technique

Now, Freight Transport is more and more important, and transport power is also increasing, and vehicle increases swift and violent, also becomes more and more important as the hub bearing of one of lorry safety component.Country truck hub bearing working life by ten thousand kilometers of 200,000 kilometers speed-raisings to 50 (developed country even bring up to 1,000,000 kilometers), reliability requirement reaches 99%, proposes as a kind of strong basis project.

Freight car bearing is bigger because of bearing load, and stream time is long, so bearing heats up easily, thereby the bearing premature fatigue is peeled off, and it is bonding that the rolling element of bearing inside and lasso are taken place, and makes bearing failure.

Summary of the invention

For solving the problem that existing hub bearing exists, prolong the working life of hub bearing, improve safety reliability, the invention provides a kind of anti-bonding long-life truck hub bearing unit, in the middle of two row bearing outer rings, increase seal arrangement, seal arrangement is made up of sealing shell fragment and stuffing box gland, offers aperture at stuffing box gland.When automobile in the process of moving, the hub bearing inside temperature raises, pressure increases, promoting the sealing shell fragment moves up, the aperture that gas is offered by flange plate emits, thereby reduce the bearing inside temperature and reduce pressure, so circulation reaches automobile temperature pressure in running and guarantees within the specific limits.

For realizing above-mentioned purpose, technological scheme of the present invention is: anti-bonding long-life truck hub bearing unit comprises two bearings, flange plate and snap rings; At the inner seal ring of installing of two single row bearings, seal ring fixedly is fitted in the flange plate by snap ring, offers aperture at flange plate; Increase seal arrangement in the middle of the two row bearing outer rings, seal arrangement is made up of sealing shell fragment and stuffing box gland, and an end that seals shell fragment is fixed in stuffing box gland, offers aperture at stuffing box gland, and offers aperture on this aperture and the flange plate and communicate.The affixed mode preferred weld of sealing shell fragment and stuffing box gland.When automobile in the process of moving, the hub bearing inside temperature raises, pressure increases, promoting the sealing shell fragment moves up, the aperture that gas is offered by flange plate emits, thereby reduce the bearing inside temperature and reduce pressure, so circulation, reaching automobile temperature pressure in running guarantees within the specific limits, prevented because high temperature makes the rolling element of bearing inside and lasso take place bonding, prevented that also the bearing seal that causes was lost efficacy because bearing internal temperature rise high pressure is big, reached long lifetime and the safety reliability of bearing.

Description of drawings

Fig. 1 is the structural representation of truck hub bearing unit.

Among the figure: 1, inner ring, 2, retainer, 3, the outer ring, 4, flange plate, 5, the sealing shell fragment, 6, stuffing box gland, 7, roller, 8, snap ring, 9, seal ring.

Embodiment

As shown in Figure 1, anti-bonding long-life truck hub bearing unit comprises two bearings, flange plate (4) and snap ring (8); Bearing adopts single row bearing, comprises inner ring (1), retainer (2), outer ring (3) and roller (7); At the inner seal ring (9) of installing of two single row bearings, seal ring fixedly is fitted in the flange plate by snap ring, offers aperture at flange plate; Increase seal arrangement in the middle of the two row bearing outer rings, seal arrangement is made up of sealing shell fragment (5) and stuffing box gland (6), and an end that seals shell fragment is welded in stuffing box gland, offers aperture at stuffing box gland, and offers aperture on this aperture and the flange plate and communicate.When automobile in the process of moving, the hub bearing inside temperature raises, pressure increases, promoting the sealing shell fragment moves up, the aperture that gas is offered by flange plate emits, thereby reduce the bearing inside temperature and reduce pressure, so circulation, reaching automobile temperature pressure in running guarantees within the specific limits, prevented because high temperature makes the rolling element of bearing inside and lasso take place bonding, prevented that also the bearing seal that causes was lost efficacy because bearing internal temperature rise high pressure is big, reached long lifetime and the safety reliability of bearing.

Claims (2)

1. anti-bonding long-life truck hub bearing unit comprises two bearings, flange plate and snap rings; At the inner seal ring of installing of two single row bearings, seal ring fixedly is fitted in the flange plate by snap ring, offers aperture at flange plate; It is characterized in that: increase seal arrangement in the middle of the two row bearing outer rings, seal arrangement is made up of sealing shell fragment and stuffing box gland, and an end that seals shell fragment is fixed in stuffing box gland, offers aperture at stuffing box gland, and the aperture of offering on stuffing box gland aperture and the flange plate communicates; When automobile in the process of moving, the hub bearing inside temperature raises, pressure increases, promoting the sealing shell fragment moves up, the aperture that gas is offered by flange plate emits, thereby reduce the bearing inside temperature and reduce pressure, so circulation reaches automobile temperature pressure in running and guarantees within the specific limits.
2. truck hub bearing unit according to claim 1 is characterized in that, the affixed mode of described sealing shell fragment and stuffing box gland is welding.
