The specific embodiment
The present invention mainly is lubricated to the bearing of balance suspension assembly drum, adopts in liquid lubricating oil is immersed in the bulging composite bush of balance shaft and bearing; Further, add an Oil container in the outer end of bearing drum, the liquid lubricating oil of filling in this Oil container, the liquid level of this lubricating oil are higher than bearing drum composite bush.Details are as follows for particular content:
Like Fig. 1, shown in Figure 2, the balance suspension assembly comprises balance shaft 1 and bearing drum 2, and balance shaft 1 is connected through composite bush 3 assemblings with bearing drum 2, and the outer end is provided with end cap 4, and the inner is provided with oil sealing 5.
The internal face 31 of composite bush 3 and contact surface 12 free-running fits of balance shaft 1.
During mode of operation, balance shaft 1 relatively rotates with bearing drum 2, produces contact friction between the contact surface 12 of balance shaft 1 and the internal face 31 of composite bush 3.Be the damage of reducing friction, in the tolerance clearance of the internal face 31 of contact surface of balance shaft 1 12 and composite bush 3, be filled with lubricating oil 6.
Lubricating oil 6 of the present invention is to select liquid lubricating oil for use, and this liquid state lubricating oil 6 is annotated into from the top of bearing drum 2, and is stored between the outer face 22 of end cap 4 and bearing drum 2; This liquid level 61 that is stored in the lubricating oil 6 between end cap 2 and the bearing drum outer face 22 is higher than the connecting bore 21 of bearing drum 2.
Further, high level is offered oil filling port 41 above end cap 4, and end cap 4 caved inward from middle inside forms an accommodation space 42; Oil filling port 41 is communicated with accommodation space 42; The top of this accommodation space 42 is higher than the connecting bore 21 of bearing drum 2, is used to accommodate the liquid lubricating oil 6 that injects from oil filling port 41; In this liquid state lubricating oil 6 all is immersed in the end face of end face of balance shaft 1 11 and composite bush 3.
Liquid lubricating oil 6 by gravitys in this accommodation space 42 enter into the tolerance clearance of balance shaft 1 and composite bush 3, between the internal face 31 of the contact surface 12 of balance shaft 1 and composite bush 3, constitute lubricant film 62.Because lubricating oil liquid level 61 is higher than the connecting bore 21 of bearing drum 2; Under the strong flowing power effect of gravity and liquid lubricating oil; This liquid state lubricating oil 6 fills up the tolerance clearance of internal face 31 of contact surface 12 and the composite bush 3 of whole balance shaft gradually, forms the lubricant film 62 of the contact surface 12 that wraps up balance shaft 1 fully, in the course of the work; The same reason of flowing power by force owing to gravity and liquid lubricating oil; This lubricant film 62 can keep constantly, makes the stable flow friction of formation between balance shaft 1 and the composite bush 3, has overcome the damage of semi-dry friction to balance shaft 1.
Balance suspension assembly of the present invention adopts liquid lubricating oil that balance shaft 1 and composite bush 3 are carried out the lubricated of immersion type, can continue to keep the oil film 62 on balance shaft 1 and composite bush 3 surfaces; Make to lubricate and put in place fully; The balance suspension bearing drum that is specially adapted to heavy mine dumping car is lubricated, has broken through the lubricating method of traditional semisolid lubricant, and lubricant effect get a qualitative improvement; Prolonged the service life of balance shaft; Reduced balance shaft repair and replacement cost, the vehicle operating efficiency is able to guarantee, has solved the balance suspension bearing drum lubrication problem of heavy mine dumping car well.
As shown in Figure 2; The bearing drum lubricating system of balance suspension assembly of the present invention mainly is made up of the liquid Oil container 4 that is arranged on bearing drum 2 ends; Oil container 4 has oil filling port 41 and oil storage chamber 42, and wherein oil filling port 41 is opened in the top of Oil container 4, is communicated with oil storage chamber 42; The height of oil storage chamber 42 is higher than the connecting bore 21 of bearing drum 2.
This Oil container 4 is installed in the outer face 22 of bearing drum 2 through fastener sealing, the liquid lubricating oils of filling in the oil storage chamber 42, and the liquid level of liquid lubricating oil is higher than bearing drum composite bush 3, and balance shaft 1 and composite bush 3 are immersed in this liquid state lubricating oil.
In the present embodiment, Oil container 4 like Fig. 3 and shown in Figure 4, has the sealing mounting ring 40 of annular and the oil storage chamber 42 of indent for being the end cap of bowl structure roughly, and oil filling port 41 is opened in the roughly bowl-type outer wall of Oil container 4, is communicated with oil storage chamber 42.
Wherein the volume of oil storage chamber 42 is about about 0.5 liter, in order to hold enough lubricating oils.
The bearing drum lubricating system of this balance suspension assembly; Through installing liquid Oil container additional, the liquid lubricating oil of annotating carries out the lubricated of immersion type to balance shaft and composite bush, can continue to keep the oil film on balance shaft and composite bush surface; Make to lubricate and put the phenomenon that can not occur dry grinding in place.This apparatus structure is simple; Utilize existing structure to improve, cost is low, assembles easy to maintenance; Easy to operate; Thereby make vehicle be in operation because balance shaft and composite bush have the oil film protection, the lubricant effect of balance shaft and bearing drum composite bush is improved greatly, actv. has prolonged the service life of balance shaft and composite bush.
Non-so limitation protection scope of the present invention so use the equivalence techniques variation that specification sheets of the present invention and diagramatic content do such as, all is contained in protection scope of the present invention.
