Abstract

The utility model discloses a bearing device. The bearing device comprises a bearing seat, a bearing arranged in the bearing seat and a main shaft, wherein a bearing ring is sheathed on the main shaft, the bearing ring is fixed on the main shaft through a screw, an oil slinger is sheathed on the outer side of the bearing ring, the outer edge of the oil slinger is in clearance fit with a step surface on the bearing seat, the oil slinger is locked with the main shaft through a locking nut, and an oil retaining ring is clamped between a bearing outer ring of the bearing and a cup shoulder of the bearing seat. According to the bearing device disclosed by the utility model, through the arrangement of the oil slinger, the entrance of a large quantity of pollutants can be blocked; and through the arrangement of the oil retaining ring, grease can be ensured to be retained in a region around the bearing, a lubricating oil membrane is formed in a slit between the oil retaining ring and the main shaft, and pollutants can be prevented from entering the bearing.

Description

A kind of bearing means

Technical field

The utility model discloses a kind of bearing means.

Background technique

Bearing self on some present bearing means is not established seal ring, the formation clearance seal that only depends on main shaft to cooperate with bearing support, namely between main shaft and bearing support, leave a sealing slit, can satisfy general seal request, but under the heavily contaminated operating mode, this seal form is for keeping out environmental contaminants, prevent that the excessive aspect of grease is unsatisfactory, and the user is more and more higher to the performance requirement of dustproof, the waterproof of bearing means, anti-leakage of oil.

The model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bearing means of good sealing effect is provided.

For achieving the above object, the technical solution of the utility model is: a kind of bearing means, comprise bearing support, be loaded on bearing and main shaft in the bearing support, be set with bearing ring on the described main shaft, described bearing ring is fixed on the main shaft by screw, and the bearing ring outside is socketed with oil thrower, the step surface Spielpassung on described oil thrower external side brim and the bearing support, oil thrower is by locking nut and principal shaft locking, is arranged with flinger ring between the seat shoulder of the bearing outer ring of bearing and bearing support.

The beneficial effects of the utility model are: by the setting of oil thrower, can stop entering of a large amount of pollutants; By the setting of flinger ring, can guarantee that grease is retained in bearing zone on every side, and in the slit of flinger ring and main shaft, form lubricant film, can prevent that pollutant from entering bearing.

Description of drawings

Fig. 1 is schematic representation of the present utility model.

Among the figure: bearing support 1, seat shoulder 11, step surface 12, bearing 2, bearing outer ring 21, main shaft 3, bearing ring 4, screw 5, oil thrower 6, locking nut 7, flinger ring 8.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Figure 1, a kind of bearing means, comprise bearing support 1, be loaded on bearing 2 and main shaft 3 in the bearing support 1, be set with bearing ring 4 on the described main shaft 3, described bearing ring 4 is fixed on the main shaft 3 by screw 5, and bearing ring 4 outsides are socketed with oil thrower 6, step surface 12 Spielpassung on described oil thrower 6 external side brims and the bearing support 1, oil thrower 6 is arranged with flinger ring 8 by locking nut 7 and main shaft 3 lockings between bearing outer ring 21 and the seat of bearing support 1 of bearing 2 take on 11.

In main shaft 3 operation process, bearing ring 4, oil thrower 6 and locking nut 7 are with main shaft 3 rotations, step surface 12 Spielpassung on oil thrower 6 external side brims and the bearing support 1, can stop entering of a large amount of pollutants, between the seat shoulder 11 of bearing outer ring 21 and bearing support 1, be arranged with flinger ring 8, flinger ring 8 is relative static with bearing support 1 and bearing outer ring 21, can guarantee that grease is retained in bearing 2 zone on every side, and in the slit of flinger ring 8 and main shaft 3, form lubricant film, can prevent that pollutant from entering bearing 2.
