In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of instructions such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of device or the element of instruction or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
Fig. 2 is according to the front elevational schematic of the utility model one embodiment's spline housing oil gun.Fig. 3 is the schematic side view of the oil gun of spline housing shown in Fig. 2.Fig. 4 is the schematic diagram of the working state of spline housing shown in Fig. 2.
The oil gun of spline housing shown in Fig. 21 comprises bar 101, and described bar 101 inside have oiling passage, and oiling feeder connection end 102 is connected with grease gun 2, and described oiling channel outlet 103 is positioned at bar 101 outer surface center.
The material of bar 101 is preferably nylon 66.Nylon 66 has lightweight (for example, being about 0.01kg according to the utility model one embodiment's spline housing oil gun overall weight), low price, market are originated wide advantage.And the easy machine shaping of nylon 66, and there is certain toughness, not frangibility.Nylon 66 friction factor are lower, operate light, smooth and easy with spline housing 6 while coordinating upper and lower drawing.But the material of bar 101 is not limited to nylon 66, can be also other materials, such as metal material etc.
Advantageously, the outer surface of bar 101 has spline, is understandable that, described spline is to match with the spline endoporus of spline housing.The spline of bar 101 cooperatively interacts with certain interval with supporting spline housing internal surface, is convenient to smearing of grease.The gap (one-sided gap) of spline and the internal surface of supporting spline housing preferably in the scope of 0.2mm to 1mm, more preferably 0.3mm to 0.5mm.
In the illustrated embodiment, spline housing oil gun 1 has multiple oiling channel outlets 103, is convenient to lubricant grease and evenly spreads upon in spline housing, and the number of oiling channel outlet 103 is preferably identical with the number of teeth of the spline on bar 101 outer surfaces.
Advantageously, oiling channel outlet 103 is positioned at same position place (referring to Fig. 2, the left end of each oiling channel outlet and bar 101 distance is identical) at axial direction, is convenient to spline housing oil gun 1 grease is evenly spread upon the inside of spline housing 6.
Referring to Fig. 2, tooth root place or the tooth top place of the spline of 103 bar 101 outer surface center of oiling channel outlet.Oiling channel outlet 103 also can be positioned at left part or the right part (left part shown in Fig. 2 or right part) of bar 101, but, the left part that oiling channel outlet 103 is positioned at bar 101 easily causes spline housing oil gun 1 to start apply grease from the starting point of spline housing 6 internal splines, be positioned at the waste that right part easily causes grease, so oiling channel outlet 103 is preferably the center that is positioned at bar 101.
Referring to Fig. 2 and Fig. 3, described oiling passage comprises axial passage and radial passage.Axial passage extends to bar axial length center along bar axial direction, and radial passage is along radially mind-set bar outer surface extension from bar radially of bar.Be understandable that, the radially inner side end of described radial passage is communicated with described axial passage, and radial outside end to be described oiling channel outlet 103(each corresponding oiling channel outlet in radial passage).Referring to Fig. 2, oiling feeder connection end 102 is positioned at the left end of described axial passage, and oiling channel outlet 103 is positioned at one end that is positioned at bar 101 outer surfaces of described radial passage.It is pointed out that described oiling passage is not limited to the structure shown in figure, the oiling passage of other shapes that meets oiling demand is also passable, for example, also can take the radial passage or the even bending oiling passage that tilt.But consider the simplicity of manufacture, axial passage and radial passage are preferably beeline channel.
One end (oiling feeder connection end 102) that oiling passage is connected with grease gun 2 locates to have internal thread, for being threaded connection and being fixed together with grease gun 2.
Referring to Fig. 2, on spline housing oil gun 1, oiling feeder connection end 102 at one end arranges the second round boss 106, be convenient to the installation of grease gun 2, and can metal shell 106 be set at described the second round boss 106 places, strengthen the reliability being threaded, extend the working life of spline housing oil gun 1.
Referring to Fig. 2, on spline housing oil gun 1, at one end relative one end be provided with the first round boss 104 with 102, oiling feeder connection end, be convenient to when narrower in spline housing bottom, spline housing oil gun 1 can insert the bottom of spline housing 6, ensures that the starting point of the spline that spline housing oil gun 1 can be on spline housing 6 starts as the even apply grease of spline housing 6.
Referring to Fig. 4, when oiling, spline housing oil gun 1 is together by a threaded connection with grease gun 2, and when oiling, spline housing oil gun 1 inserts the bottom of spline housing 6, starts oiling and robs 2 and carry on evenly afterwards, can form the uniform oil film of one deck on spline housing 6 internal splines surfaces.
Above-mentioned spline housing oil gun has been broken splined shaft, the traditional oiling mode of spline housing, uses first oil gun to be lubricated spline engagement pair.And above-mentioned spline housing oil gun is simple in structure, low cost of manufacture, the lubricated difficulty while having avoided lubricating again after splined shaft, spline housing engagement in prior art and the problem of oiling inequality, effectively saved lubricant grease, and effectively improve working efficiency, reduced labor intensity.
Finally it is to be noted: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit.Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment's technological scheme of the utility model.
