Abstract

The utility model discloses a vertical bearing device, which comprises a bearing block, a bearing, a spindle, and an upper bearing end cover and a lower bearing end cover which are connected with the upper and lower ends of the bearing block, wherein the upper end of the spindle is provided with a shaft shoulder; a dustproof cover is arranged on the shaft shoulder; a gap is formed between the inner side of the dustproof cover and the top of a bending plate of the upper bearing end cover; the edge of the dustproof cover downwards extends to form a gap with the outer surface of the bending plate of the upper bearing end cover so as to form a shaft seal; an upwards recessed shaft is arranged below the shaft shoulder of the lower end of the spindle; and the bending plate on one side of the lower bearing end cover stretches into the shaft. Compared with the prior art, the vertical bearing device is soaked in thin oil, the bearing is fully lubricated, oil is not leaked, the bearing is simple in structure, the service life of the bearing is greatly prolonged, and the maintenance amount is greatly reduced.

Description

The vertical bearing device

Technical field

The utility model relates to a kind of bearing means, especially a kind of vertical bearing device that can prevent leakage of oil.

Background technique

At present; Known its structure of vertical rolling bearing pedestal includes bearing support body and the top bearing cover and lower bearing end cap and the contact-type oil sealing that are contained in these bearing support body two ends; The bearing support of this structure can only be used grease lubrication; And use a period of time will leakage of oil, and the bearing oil starvation causes damage easily.

The model utility content

The utility model provides a kind of vertical bearing device, and it can solve the problem of existing vertical shaft bearing easy oil leakage.

In order to solve the problems of the technologies described above; The technological scheme that the utility model adopted is: it include bearing support, bearing, main shaft, with the bearing support top bearing cover and the lower bearing end cap that are connected of two ends up and down; It is characterized in that: there is the shaft shoulder described main shaft upper end, and dust-proof cover is housed on the shaft shoulder, and the inboard flap top with top bearing cover of this dust-proof cover is gapped; The dust-proof cover edge forms the gap to the flap outer surface that extends below with said top bearing cover, constitutes the axle envelope; The shaft shoulder of said main shaft lower end has the axle armpit that makes progress recessed, and the flap of said lower bearing end cap one side stretches in the said axle armpit.

In the technique scheme, scheme is more specifically: said all shoulder heights of said main shaft upper end are in the flap top of said top bearing cover.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

Because dust-proof cover on the main shaft shaft shoulder and top bearing cover Spielpassung form the axle envelope, the lower bearing end cap has a side flap to stretch to the axle oxter of main shaft, is equivalent to dust-proof cover, top bearing cover and lower bearing end cap like this and surrounds a container; Bearing is contained in the container; Can be immersed in the thin oil, bearing obtains sufficient lubrication and can leakage of oil, and is simple in structure always; Bearing is prolonged working life greatly, and maintenance significantly reduces.

Description of drawings

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

Embodiment

Below in conjunction with the accompanying drawing instance, the utility model is done further to detail:

Like the described present embodiment of Fig. 1, it includes bearing support 1 and top bearing cover that is contained in these bearing support two ends 2 and lower bearing end cap 3, and bearing support 1 has main shaft 4; There is the shaft shoulder 4-1 main shaft 4 upper ends, and shaft shoulder 4-1 goes up and is fixedly connected with dust-proof cover 6 with bolt 5, and dust-proof cover 6 rotates with main shaft 4 simultaneously; Can foreign body be thrown away, materials such as secondary water can't get in the bearing support 1, and the inboard flap 2-1 top with top bearing cover 2 of this dust-proof cover is gapped; Dust-proof cover 6 edges form the gap to the flap 2-1 outer surface that extends below with top bearing cover 2, constitute the axle envelope, because dust-

proof cover

6 and 2 of top bearing covers are gapped; Oil gas can come out in bearing support body 1, and the shaft shoulder of main shaft 4 lower ends has the axle armpit 4-2 that makes progress recessed, and the flap 3-1 of lower bearing end cap 3 one sides stretches under the axle armpit 4-2 of main shaft 4; Be equivalent to dust-proof cover 6, top bearing cover 2 and lower bearing end cap 3 like this and surround a container, bearing 7 is contained in the container, the full bearing of promptly available thin oil bubble; Oil can't flow out, throw away, and bearing is immersed in the thin oil, and bearing obtains sufficient lubrication and oil-proof; Simple in structure, bearing is prolonged working life greatly, and maintenance significantly reduces.

Claims

1. vertical bearing device; Include bearing support, bearing, main shaft, with the bearing support top bearing cover and the lower bearing end cap that are connected of two ends up and down; It is characterized in that: there is the shaft shoulder described main shaft upper end, and dust-proof cover is housed on the shaft shoulder, and the inboard flap top with top bearing cover of this dust-proof cover is gapped; The dust-proof cover edge forms the gap to the flap outer surface that extends below with said top bearing cover, constitutes the axle envelope; The shaft shoulder of said main shaft lower end has the axle armpit that makes progress recessed, and the flap of said lower bearing end cap one side stretches in the said axle armpit.

2. vertical bearing device according to claim 1 is characterized in that: said all shoulder heights of said main shaft upper end are in the flap top of said top bearing cover.
