Abstract
The invention relates to the technical field of vehicle component processing equipment, in particular to a shaft housing sealing structure for a Steyr balance shaft. A ring-shaped rectangular slot is formed in one side, connected with an end cover, of the shaft housing; an end surface sealing ring is embedded into the ring-shaped rectangular slot; a connecting end surface between the shaft housing and the end cover is filled with sealant to form a double-layer sealing effect, so that oil leakage of the end cover is avoided. A ring-shaped mounting slot is formed in one side, connected with a shaft-driven bracket, of the shaft housing, one side of a dustproof cover is clamped in the ring-shaped mounting slot, a gap between the shaft housing and the shaft-driven bracket is filled with the other side of the dustproof cover, so that dust, small particles, rainwater and the like can be prevented from entering a shaft housing cavity, and the components in the cavity are effectively prevented from being corroded and losing efficiency. Two oil sealing retainers which are arranged in parallel are arranged on the inner side of one side, connected with the shaft-driven bracket, of the shaft housing, and a first oil seal and a second oil seal are arranged in the two oil sealing retainers respectively. When oil seal loses efficiency, the assembly can still continuously work without leaking oil.
Description
Technical field
The present invention relates to vehicle component technical field of processing equipment, specifically relate to a kind of axle housing sealing configuration of steyr trunnion shaft.
Background technique
At present, quarry tipper heavily card trunnion shaft suspension assembly adopts steyr structure mostly, and there are the quality problems of axle housing leakage of oil, leakage of oil point mainly contains end cap and oil sealing two place, and end cap leakage of oil is mainly poorly sealed, and oil sealing leakage of oil is single oil seal lip wearing and tearing mainly.In addition, a large amount of dust, short grained silt enters in axle housing cavity from single oil sealing, aggravates single oil sealing degree of wear, and single oil sealing, once lose efficacy, causes assembly leakage of oil.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide a kind of salable reliable performance, assemble the axle housing sealing configuration of simple steyr trunnion shaft.
To achieve these goals, the technical solution adopted in the present invention is: a kind of axle housing sealing configuration of steyr trunnion shaft, comprise the axle housing be connected with axle belt supporting frame, the other end of axle housing is connected with end cap, it is characterized in that: the side that described axle housing is connected with end cap offers ring-type rectangle groove, be embedded with end-face seal ring in this ring-type rectangle groove, and the connecting end surface between axle housing and end cap is filled with sealer; The side that described axle housing is connected with axle belt supporting frame offers ring-type mounting groove, and dust-proof cover side is sticked in this ring-type mounting groove, and opposite side is by the gap-fill between axle housing and axle belt supporting frame; The inwall of the side that described axle housing is connected with axle belt supporting frame offers the oil sealing shelves of two parallel arrangements, be respectively arranged with the first oil sealing and the second oil sealing in two oil sealing shelves, the internal diameter near the second oil sealing of axle belt supporting frame side is greater than the internal diameter of the first oil sealing to form gradient oil sealing.
The axle housing sealing configuration of steyr trunnion shaft of the present invention, its beneficial effect shows:
Axle housing arranges dust-proof cover, can prevent dust, granule, rainwater etc. from entering axle housing inside cavity, component corrosion, inefficacy in available protecting chamber.Assemble two single oil sealings, when an oil seal failure, assembly still can work on, and is unlikely to assembly leakage of oil.Axle housing end face arranges annular rectangle groove, and assembled end O RunddichtringO, end cap adds glue, forms dual layer sealing effect, avoids end caps leakage of oil.The axle housing sealing configuration of this steyr trunnion shaft can meet heavy type mining dump truck load bearing requirements, reliable performance, structure be simple, produce and assembling easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the axle housing sealing configuration of steyr trunnion shaft of the present invention.
Fig. 2-4 is followed successively by the structural representation of the second oil sealing, the first oil sealing and dust-proof cover.
Embodiment
For further describing the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail.The axle housing sealing configuration of a kind of steyr trunnion shaft shown in Fig. 1; comprise the axle housing 10 be connected with axle belt supporting frame; the other end of axle housing 10 is connected with end cap 11; the side that axle housing 10 is connected with end cap 11 offers ring-type rectangle groove; end-face seal ring 12 is embedded with in this ring-type rectangle groove; and the connecting end surface between axle housing 10 and end cap 11 is filled with sealer, thus form double-layer seal protection at the end cap end of axle housing.
The side that axle housing 10 is connected with axle belt supporting frame offers ring-type mounting groove 15, and dust-proof cover 16 (structure as shown in Figure 4) side is sticked in this ring-type mounting groove 15, and opposite side is by the gap-fill between axle housing 10 and axle belt supporting frame.Dust-proof cover can effectively prevent dust, granule enters axle housing inside cavity, causes oil seal failure.
The inwall of the side that axle housing 10 is connected with axle belt supporting frame offers the oil sealing shelves of two parallel arrangements, the first oil sealing 13 (structure as shown in Figure 3) and the second oil sealing 14 (structure as shown in Figure 2) is respectively arranged with in two oil sealing shelves, internal diameter near the second oil sealing 14 of axle belt supporting frame side is greater than the internal diameter of the first oil sealing 13 to form gradient oil sealing, can prevent an oil seal failure and the oil leakage phenomenon that causes occurs, and two oil sealings are main plays the appearance of stopping gap oil leakage phenomenon between bearing inner race and axle housing.
Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
