Shown in Figure 1, the utility model provides a kind of driving motor and couples lubrication system with gearbox, including speed change
Case input shaft 3 (being located in gearbox 5, in detail as shown in Figure 1) and drive motor shaft 4 (are located in driving motor 7, refer to Fig. 1 institutes
Show), transmission input shaft 3 is axially arranged with through hole, and transmission input shaft 3 is socketed on by through hole in drive motor shaft 4, speed change
Lubricating arrangement is provided between case input shaft 3 and drive motor shaft 4.
A kind of driving motor provided by the utility model couples lubrication system with gearbox, compared with prior art, passes through
Lubricating arrangement between transmission input shaft and drive motor shaft is set, substantially reduces the friction of motor and retarder connection place
Effect, on the premise of power transmission reliability is ensured, makes drive splines obtain long-acting lubrication, so as to extend the use of spline
Service life, so as to reduce the loss of vehicle power or the generation for the problem that runs out of steam.
Further, the specific reality of lubrication system is coupled with gearbox as a kind of driving motor provided by the utility model
Mode is applied, lubricating arrangement includes sealing device and lubricant medium, and lubricant medium is packaged in sealing device.It will using sealing device
Lubricant medium is enclosed in drive splines position, can provide lubrication for a long time for drive splines, so as to extend the use of spline
Service life.
Specifically, sealing device includes sealing catch 1, sealing catch 1 is arranged in transmission input shaft 3 away from driving electricity
4 one end of arbor, sealing catch 1 and 3 tight fit of transmission input shaft, sealing catch 1, the free end of drive motor shaft 4 and change
Cavity 2 is formed between the through-hole wall of fast case input shaft 3, lubricant medium is packaged in cavity 2.In the present embodiment, catch 1 is sealed
In bowl-type (in detail as shown in Figure 1).It is interference fitted between sealing catch 1 and transmission input shaft 3, by pressure during practical set
Bowl seal catch is pressed into transmission input shaft 3 by machine.
Preferably, sealing device further includes O-ring seal 6, and O-ring seal 6 is arranged on drive motor shaft 4 and is kept off away from sealing
Between one end of piece 1 and the through hole of transmission input shaft 3, and O-ring seal 6 is set in drive motor shaft 4.
Further, lubricant medium is lubricating grease.Lubricating grease (English：Grease it is) to add in thickener and profit in base oil
Semisolid machine components lubricant made of sliding additive.
Lubricating grease has the following advantages compared with lubricating oil：L, with can be compared with the lubricating oil of specific viscosity, lubricating grease tool
There are higher bearing capacity and better damping shock absorption ability；2nd, due to the absorption of thickening agent structural system, lubricating grease tool
There is relatively low evaporation rate.Therefore under oil starvation grease lubrication (Starvation Lubrication) state, particularly in high temperature
In long-term operation, lubricating grease has better characteristics；It 3rd, and can specific viscosity due to the capillarity of thickening agent structure
Lubricating oil is compared, grease base plinth oil creep tendency it is small；4th, lubricating grease can form the fat circle with certain sealing function, can prevent
The only intrusion of solid or liquid pollutant is conducive to use in moist and dirty environment；5th, lubricating grease can be firmly adhered to
By on lubricated surface, also it is not lost in even if on even vertical surface is tilted.Under external force, it generates deformation, being capable of picture
Oil equally flows；Once removing external force, it is restored to reset condition again, stops flowing, therefore lubricating grease can be open or close
It seals on undesirable friction means and works；6th, the design and maintenance of equipment can be simplified with lubricating grease, it is normal oil lubrication system can be saved
Oil pump, cooler, oil filter etc. often are needed, so as to save cost of equipment；7th, since lubricating grease adhesiveness is good, not easily run off,
So satisfied lubricating status can still be kept after a shutdown by restarting；8th, usually only needed a small amount of lubricating grease being applied to lubricating grease
By lubricated surface, thus the demand of oil product can be greatlyd save, this is significant for being undoubtedly now for energy scarcity.
Further, connected between transmission input shaft 3 and drive motor shaft 4 by spline.Spline is connected in intensity, work
Skill and use aspect have following features：1st, because with directly equably making more tooth and slot on hub bore on axis, therefore join
Capacity is more uniform；2nd, because slot is shallower, stress concentration is smaller at tooth root, and the strength reduction of axis and hub is less；3rd, the number of teeth is more,
Total contact area is larger, thus can bear larger load；4th, parts on shaft and axis to neutral good, this is at a high speed and accurate machine
Device is critically important；5th, guidance quality is good, this is critically important to dynamic connection.
It is emphasized that technical solutions of the utility model key point is：1st, linkage section is coupled using spline
Transmission；2nd, lubrication system blocks transmission input shaft using Bowl seal catch；3rd, lubrication system is using O-ring seal sealing electricity
At arbor and transmission input shaft cooperation；4th, lubrication system is equipped with grease storing chamber, for storing lubricating grease, is supplemented at any time to working face
Lubrication；5th, lubrication system is lubricated using extreme pressure high temperature resistant lubricating grease.
The embodiment of the utility model in order to example and description for the sake of and provide, and be not exhaustively or will
The utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
See.Selection and description embodiment are to more preferably illustrate the principle and practical application of the utility model, and make this field
