Description
Technical field
The utility model relates to a kind of lubricating fitting, particularly relates to a kind of rotator type gear lubrication device on transfer case.
Background technique
Transfer case is a pinion unit, and its input shaft is direct or be connected by the second axle of universal driving device and speed changer, and output shaft then has some, is connected respectively through universal driving device with each ransaxle.Workpiece in transfer case mainly comprises input shaft, output shaft, sprocket wheel and Transmitted chains etc., and in transfer case course of normal operation, the lubrication of the workpiece component in transfer case all seems particularly important.
The lubricating fitting of existing transfer case internal gear, general is all arrange an oil groove in the bottom of transfer case internal gear, the oil inside oil groove is touched by the rotation of gear, play the effect of lubrication, but in the middle of practice, still also there is many problems, such as often can run in gear lubrication to be dipped in lubricant oil by one of them in a pair gear smoothly, cause the situation of insufficient lubrication, as comparatively small gear and comparatively gearwheel pairing in open type or semi-open type gear, gearwheel position is high, pinion positions is low, and because small gear diameter is less, be limited to the bearing height of pinion shaft, the situation of oil sump oil level cannot be raised, finally cause whole gear lubricity inadequate.In addition, gear in transfer case is in greasing, can not effectively lubricate miscellaneous part in transfer case (as the input shaft in transfer case, transmission chain and sprocket etc.), cause the lubricity of other workpieces in transfer case inadequate, thus effectively can not keep the lubricity of system in whole transfer case.
Model utility content
The purpose of this utility model is to provide a kind of rotator type gear lubrication device on transfer case, to solve in existing transfer case system, gear lubrication is bad, the lubricity of transfer case other workpieces interior is inadequate, causes the problem that effectively can not keep the lubricity of system in whole transfer case.
To achieve these goals, the utility model provides following technological scheme: the rotator type gear lubrication device on transfer case, comprise the oil pump mechanism be set in transfer case on input shaft, described oil pump mechanism comprises coaxial oil pump protecgulum, rotor assembly and the oil pump rear lid arranged successively, described oil pump protecgulum is provided with the oil outlet in semicircle shape, described oil pump rear lid is provided with vertically shaft-like filler opening, the external rotor that described rotor assembly comprises internal rotor and coaxially engages with internal rotor, described oil pump protecgulum, rotor assembly and oil pump rear lid are connected by screw.
The principle of this programme is such: be arranged on by this lubricating fitting on the input shaft on transfer case, and meet this device and can touch oil inside transfer case oil groove, during work, oil enters from the filler opening oil pump rear lid, enter oil pocket and arrive rotor assembly, gap is had between the external rotor of engagement and internal rotor, in the process that engagement rotates, carry out motion to oil accelerate, and due to the effect of centripetal force, finally throw away from the oil outlet oil pump protecgulum, sputter at other workpieces of gear above sump liquid level and transfer case inside (as the input shaft in transfer case, transmission chain and sprocket etc.) on, thus the gear above sump liquid level and other workpieces in transfer case are effectively lubricated, improve the lubricity of system in whole transfer case.
Preferably, the sectional shape of described external rotor is dodecagon, is provided with internal tooth in external rotor, during work, by external rotor internal tooth and the engagement of internal rotor external tooth.
Preferably, described inner rotor face is provided with external tooth, is provided with the spline connecting input shaft in transfer case in internal rotor, adopts spline joint, dismounting, easy to connect.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Reference character in Figure of description comprises: oil pump protecgulum 1, oil pump rear lid 2, oil outlet 3, filler opening 4, internal rotor 5, external rotor 6, spline 7, socket head screw 8.
As shown in Figure 1 and Figure 2, rotator type gear lubrication device on transfer case, comprise the oil pump mechanism be set in transfer case on input shaft, oil pump mechanism comprises coaxial oil pump protecgulum 1, rotor assembly and the oil pump rear lid 2 arranged successively, oil pump rear lid 2 is provided with vertically shaft-like filler opening 4, and oil pump protecgulum 1, rotor assembly are connected by socket head screw 8 with oil pump rear lid 2.
As shown in Figure 3, Figure 4, rotor assembly comprises internal rotor 5 and the external rotor 6 that engage coaxial with internal rotor 5, and internal rotor 5 surface is provided with external tooth, is provided with the spline 7 connecting input shaft in transfer case in internal rotor 5, the sectional shape of external rotor 6 is dodecagon, is provided with internal tooth in external rotor 6.
As shown in Figure 5, oil pump protecgulum 1 is provided with the oil outlet 3 in semicircle shape.
In the present embodiment, this lubricating fitting is arranged on the input shaft on transfer case, and meet this device and can touch oil inside transfer case oil groove, during work, oil enters from the filler opening oil pump rear lid 2, enter oil pocket and arrive rotor assembly, gap is had between the external rotor 6 of engagement and internal rotor 5, in the process that engagement rotates, carry out motion to oil accelerate, and due to the effect of centripetal force, finally throw away from the oil outlet 3 oil pump protecgulum 1, sputter at other workpieces of gear above sump liquid level and transfer case inside (as the input shaft in transfer case, transmission chain and sprocket etc.) on, thus the gear above sump liquid level and other workpieces in transfer case are effectively lubricated, improve the lubricity of system in whole transfer case.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
