Abstract
The invention provides a sliding bearing, which includes a base, sealing end caps and an oil-filling cup, wherein two ends of the base is fixedly connected with the sealing end cap and the oil-filling cup is equipped on the base. The sliding bearing has characteristic of that: the sliding bearing also includes a supporting sleeve and a flexible abrasion-resistant inner sleeve, an oil tank communicated with the oil-filling cup, the supporting sleeve and the flexible abrasion-resistant inner sleeve are all equipped in the base, and gap between the supporting sleeve and the two sealing end caps and the oil tank in the base composes a lubrication channel. The flexible abrasion-resistant inner sleeve is electrochemical graphite sleeve. When shaft-like motion member moving linearly in the sliding bearing, lubricating oil in the lubrication channel of the sliding bearing and gap between the shaft-like motion member and the flexible abrasion-resistant inner sleeve composes a lubricating circuit, lubrication principle accords with dynamical lubrication principle, so that the sliding bearing has good lubricating effect and long useful life, and is especially adapted for situation of heavy load and high dust.
Description
Technical field
The utility model relates to a kind of sliding bearing, is the supporting part of straight line motion rod member, is particularly suitable for heavy load, and the abominable occasion of operating mode is used.
Background technique
The existing glide bearing, it is the internal surface that the appearance of straight line motion rod member acts directly on sliding bearing sleeve, although be provided with oiling device, the lubricated boundary lubrication condition that also is in, its deficiency is: lubrication effect is not good enough, working life is short, only is suitable for underload usually, occasion that working condition is good is used.
Summary of the invention
The purpose of this utility model provides a kind of high lubricating effect, and long service life is particularly suitable for the sliding bearing that the occasion of working condition differences such as heavy load, high dust is used.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of sliding bearing, it comprises bearing, end cover, the two ends and the end cover of bearing are connected, and priming cup is housed on bearing, it is characterized in that: also comprise supporting sleeve, flexible wear-resisting interior cover is provided with the oil groove that is communicated with priming cup in bearing, be built-in with supporting sleeve at bearing, supporting sleeve be built-in with flexible wear-resisting in cover, the oil groove formation lubrication channel that the gap of supporting sleeve and two end covers and bearing are interior.Cover was the electrographite cover in described flexibility was wear-resisting.
The utility model sliding bearing, when axle type games parts in sliding bearing during moving linearly, the coaxial type games parts of lubricant oil in the sliding bearing lubricating passage constitute lubricating loop with the matching gap of flexible wear-resisting interior cover, its lubrication principle meets the hydrodynamic lubrication principle, has high lubricating effect, long service life is particularly suitable for the advantages such as occasion use of working condition differences such as heavy load, high dust.
Description of drawings
Fig. 1 is the utility model sliding bearing structure cross-sectional schematic.
Fig. 2 is an A-A generalized section among Fig. 1.
Among the figure: 1,2 end covers, 3 supporting sleeves, 4 flexible wear-resisting interior covers, 5 priming cups, 6 bearings, 7 lubrication channels, 8 gaps, 9 oil grooves.
Embodiment
Below in conjunction with accompanying drawing and example the utility model is further specified.
With reference to Fig. 1 and 2, sliding bearing has bearing 6, end cover 2, priming cup 5, supporting sleeve 3, flexible wear-resisting interior cover 4.The two ends of bearing 6 and end cover 2 are connected, priming cup 5 is contained on the bearing 6, in bearing 6, be provided with the oil groove 9 that is communicated with priming cup 5, supporting sleeve 3 is equipped with in the bearing 6, flexible wear-resisting interior cover 4 employing electrographites overlap and place in the supporting sleeve 3, and axle 1 is installed on two end covers 2 and flexible wear-resisting interior overlapping in 4.Oil groove 9 in the gap 8 of supporting sleeve 3 and two end covers 2 and the bearing 6 constitutes lubrication channel 7.Electrographite is applied mechanically commercially available electrographite and is made.Priming cup 5 adopts the commercially available prod.
Claims (2)
