Abstract
The utility model discloses full-sealed oil bath bearing combination which is characterized in that two bearings are provided, wherein the two bearings are both conical roller bearings; the two conical roller bearings are symmetrically mounted on a shaft tube; a chamber for accommodating the two conical roller bearings is formed inside a bearing seat; a through hole through which the shaft tube penetrates and limiting steps for limiting the conical roller bearings are formed in one end of the bearing seat; a bearing cover which is fixed and combined by a bolt is arranged at the other end of the bearing seat; a shaft hole through which the shaft tube penetrates is formed in the bearing cover; oil baffle rings are mounted inside the shaft holes in the bearing seat and the bearing cover; O-shaped rings are arranged on the oil baffle rings; baffle seats for limiting the positions of the two oil baffle rings are arranged on the outer sides of the two oil baffle rings. As the bearing cover and the bearing seat adopt cast pieces and are high in strength, unlikely to deform and long in service life, and the bearing components are arranged in a sealed space inside the bearing seat, lubricating oil is prevented from leaking off, dust is prevented from entering the bearings, a sufficient lubrication effect can be ensured as the bearings are constantly in an oil bath environment, small abrasion is caused, and the service lives of the bearing components are prolonged.
Description
Technical field
The utility model relates to a kind of Bearing assembly, relates in particular to a kind of for the hermetically sealed oil bath bearing combination on disc harrow.
Background technique
Disc harrow is a kind of for ploughing the farm implements in whole soil, and it needs to bear in the course of the work, and sizable axially and radial load and working environment dust is more, thus to bearing axially, radially load-carrying properties and sealability are had relatively high expectations.Mainly contain two kinds of forms for the bearing combination of disc harrow at present, one is the combination of punched bearing, as shown in Figure 1, its bearing support is made up of steel plate punched, although structure is relatively simple, its bulk strength deficiency, load is easily distortion and occur damaged or stuck when large, working life is shorter, and bearing need be selected special self-aligning stuffing box bearing; Another kind of is the combination of PQZ bearing, as shown in Figure 2, its bearing support adopts foundry goods, intensity has certain reinforcement, but it adopts rubber parts as Sealing, and the easily generation of working under the more environment of dust is worn and torn and affects sealability, dust easily enters in bearing, affect its lubrication effect, cause bearing wear very fast, working life is shorter.
Summary of the invention
For overcoming above-mentioned technical problem, the utility model provides a kind of intensity high, and load carrying capacity is large, and good sealing effect can ensure that internal bearings part is under sufficient lubrication environment, extends thus the hermetically sealed oil bath bearing combination in working life of bearing composite entity.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of hermetically sealed oil bath bearing combination, comprise bearing support, bearing and central siphon, and it is characterized in that: described bearing is provided with two, be taper roller bearing, two taper roller bearing symmetries are installed on central siphon; In bearing support, be provided with the cavity that holds two taper roller bearings, bearing support one end is provided with the via hole passing for central siphon and the limited step that limits this side taper roller bearing, the bearing support the other end is provided with the bearing cap fixing by bolt combination, and bearing cap is provided with the axis hole passing for central siphon; In axis hole on described bearing support and bearing cap, flinger ring is installed, flinger ring is provided with O type circle, and two described flinger ring outsides are provided with the block seat that its position is limited, and block seat is fixed in central siphon outer wall; Described bearing cap and bearing support all adopt foundry goods.
Described bearing support is provided with oil hole, and oil hole is provided with plug screw.
Described central siphon two ends are installed on interior pad and outer pad.
Described bearing support one side is provided with fixed base, and opposite side is provided with the dust-break backplate of arc.
The utlity model has following beneficial effect: because bearing cap, bearing support adopt foundry goods, intensity is high, not yielding, long service life; And bearing part in bearing support in seal space, lubricant oil can not leak, dust can not enter, and under oil bath environment and can ensure sufficient lubrication effect, weares and teares little all the time, has extended the working life of bearing part.
