Abstract
The utility model discloses a novel cross universal joint, including the universal joint body, be equipped with main pump nozzle on the universal joint body, main pump nozzle is through establishing at this internal oiling passageway of universal joint, four concave vessel of steel that access to the universal joint body, every concave vessel of steel top center of universal joint body all is equipped with additional pump nozzle, additional pump nozzle is located concave vessel of steel's oiling passageway intercommunication separately respectively, when main pump nozzle accesss to certain oiling passageway emergence jam of four concave vessel of steel, can be through additional pump nozzle, to the direct oiling of kingpin in the concave vessel of steel of certain lubricated node, lubricate. Will make four lubricated nodes like this, the lubrication is unanimous, has prolonged the life of cross universal joint.
Description
Technical field
The utility model relates to a kind of link, particularly a kind of universal joint cross.
Background technique
Usually, good lubrication can reduce the wearing and tearing of universal joint, and in order to prevent universal joint earlier period damage, maintenance regulation will use gear oil, but in real work conveniently, cannot use gear oil, and most of universal joint all uses butter.New universal joint reaches three to five months about use, during each maintenance note butter, 4 steel Yuan and needle roller can enter butter lubrication, but three to five months with butter in rear universal joint steel Yuan and in oil duct, along with the change of environment, easily evaporation can form harder soap matter, the not oil-feed of one or two steel Yuan needle roller is there will be in upper maintenance oiling once, because the pressure in four steel Yuan and oil duct is different, so the high steel Yuan of pressure and needle roller not oil-feed, the oil-feed that pressure is low, will cause like this in four steel Yuan and always have one or two not oil-feed, certain steel Yuan needle roller that can not get lubricating after three to five months will excessive wear, looseness, if needle roller seriously can be caused to come off, oil sealing damages, universal joint noise is very large.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of novel universal joint cross of long service life.
For achieving the above object, the utility model provides following technological scheme: novel universal joint cross, comprise universal joint body, universal joint body is provided with main pump nozzle, main pump nozzle leads to four steel Yuan of universal joint body by being located at the intrinsic oiling passage of universal joint, each steel Yuan top middle portion of described universal joint body is equipped with an additional pump nozzle, each additional pump nozzle respectively with the oiling channel connection being positioned at respective steel Yuan.
Preferably, needle roller is equipped with inside each steel Yuan.
Adopt technique scheme, an additional pump nozzle is respectively established in each steel Yuan top middle portion of universal joint, when there is blocking in the oiling passage that main pump nozzle leads to four steel Yuan, can by additional pump nozzle respectively to oiling in four steel Yuan, lubricate, thus extend the working life of universal joint.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is External view of the present utility model;
Wherein, 1. the main pump nozzle 3. of universal joint body 2. adds pump nozzle 4. oiling passage 5. steel Yuan 6. needle roller.
Embodiment
Below in conjunction with accompanying drawing, by the description to embodiment, the utility model is described further:
As shown in Figure 1, a kind of novel universal joint cross of the utility model, comprise universal joint body 1, universal joint body 1 is provided with main pump nozzle 2, main pump nozzle 2 leads to four steel Yuan 5 of universal joint body 1 by the oiling passage 4 be located in universal joint body 1, each steel Yuan 5 end of universal joint body 1 is equipped with additional pump nozzle 3, and additional pump nozzle 3 is communicated with the oiling passage 4 in respective steel Yuan 5 with position respectively, is equipped with needle roller 6 inside each steel Yuan 5.
The utility model offers additional pump nozzle 3 in the top middle portion of each steel Yuan 5 of universal joint body 1, when there is blocking in certain passage of oiling passage 4 that main pump nozzle leads to 2 to four steel Yuan, can by additional oil nozzle 3 directly to oiling in steel Yuan 5, lubricate, thus extend the working life of universal joint, and structure is simple, easily manufactured, cost is low, is preferably used in the use of medium-sized, motorbus and lorry transferring power.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. novel universal joint cross, described universal joint body is provided with main pump nozzle, main pump nozzle is by being located at the intrinsic oiling passage of universal joint, lead to four steel Yuan of universal joint body, it is characterized in that: each steel Yuan top middle portion of described universal joint body is equipped with an additional pump nozzle, each additional pump nozzle respectively with the oiling channel connection in respective steel Yuan.
2. novel universal joint cross according to claim 1, is characterized in that: be equipped with needle roller inside described each steel Yuan.
