Abstract
The utility model relates to the technical field of press machines, in particular to a press machine rotary kinematic pair bearing lubricating structure which comprises a gear shaft. The gear shaft is connected into an oil pool in a supporting mode through bearings arranged at two ends. The press machine rotary motion supplementary bearing lubricating structure is characterized in that a continuous spiral groove used for lubricating is formed in each bearing. According to the continuous spiral groove lubricating structure, in the process of rotation of the gear shaft, lubricating oil in the oil pool can be conveyed into the bearings automatically through the continuous spiral grooves so that a rotary kinematic pair is lubricated, a single lubricating unit does not need to be added, and high oil level in the oil pool is avoided. The lubricating structure is simple, reasonable in design and capable of ensuring long-time continuous regular work of a lubricating system.
Description
Technical field
The utility model relates to the press technologies field, particularly a kind of press machine supplementary bearing screw lubrication structure that rotatablely moves.
Background technique
The rotary motion pair lubricating structure of the press machine gear shaft of prior art needs to increase in addition lubrication unit, and oil injecting lubricating, guarantee the rotary motion pair proper motion separately.in this structure, gear shaft is arranged in oil sump, oil sump only is used for gear lubrication, the gear shaft two end supports has bearing, be provided with discontinuous circumferential groove in bearing, gear can not take the oil in oil sump in bearing in rotary course, can not guarantee the lubricated of bearing, lubrication unit must be increased in addition lubricated separately to bearing, the shortcoming of this kind lubricating structure is: the lubricant oil of the lubrication unit that increases separately constantly is injected in oil sump, cause the oil in oil sump constantly to increase, finally can make the oil in oil sump too much, cause oil sump oil storage again, lubricious system cisco unity malfunction.
The model utility content
The utility model provides a kind of simple in structure, reasonable in design, and can avoid the too high press machine rotary motion pair bearing lubrication structure of lubricant level in oil sump for the problem that prior art exists.
The purpose of this utility model is achieved in that a kind of press machine rotary motion pair bearing lubrication structure, comprises gear shaft, and described gear shaft is connected in oil sump by the bearings at two ends, is provided with in described bearing for lubricated continuous helical groove.
Adopt continuous helical groove lubricating structure of the present utility model, in the gear shaft rotation process, can automatically the lubricant oil in oil sump be brought in bearing by the continuous helical groove rotary motion pair is lubricated, needn't set up in addition independent lubricious unit, avoid the oil level in oil sump too high.Therefore lubricating structure of the present utility model is simple, reasonable in design, can guarantee the long-time continuous normal operation of lubricious system.
For guaranteeing the lubricated work normally of continuous helical groove, the direction of the continuous helical groove in described gear shaft bearings at both ends is respectively symmetrical left-handed continuous helical groove and dextrorotation continuous helical groove.
As another improvement of the present utility model, described bearing is the copper bearing.
Description of drawings
Fig. 1 is press machine rotary motion pair bearing lubrication structure schematic diagram of the present utility model.
Fig. 2 is with the bearing structure schematic diagram of discontinuous circumferential groove in prior art.
Fig. 3 is the bearing structure schematic diagram with the continuous helical groove of the present utility model.
Wherein, 1 bearing; 2 gear shafts; 3 oil sumps; 4 continuous helical grooves.
Embodiment
As shown in figures 1 and 3, for press machine rotary motion pair bearing lubrication structure of the present utility model, comprise gear shaft 2, gear shaft 2 passes through bearing 1 support and connection at two ends in oil sump 4, be provided with in bearing 1 for lubricated continuous helical groove 4, and bearing 1 is the copper bearing; For guaranteeing the normal lubricated work of continuous helical groove 4, the direction of the continuous helical groove 4 in gear shaft 2 bearings at both ends 1 is respectively symmetrical left-handed continuous helical groove and dextrorotation continuous helical groove.
Adopt continuous helical groove lubricating structure of the present utility model, in gear shaft 2 rotation processes, can automatically the lubricant oil in oil sump 3 be brought to by continuous helical groove 4 that bearing 1 is interior to be lubricated rotary motion pair, needn't set up in addition independent lubricious unit, avoid the oil level in oil sump 3 too high.Therefore lubricating structure of the present utility model is simple, reasonable in design, can guarantee the long-time continuous normal operation of lubricious system.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in the scope of the utility model protection.
Claims (3)
