Specific embodiment
In order that the application the technical staff in the technical field is more clearly understood that the application, below in conjunction with the accompanying drawings,
Technical scheme is described in detail by specific embodiment.
Referring to Fig. 1, the invention discloses a kind of driven roll transmission side bearing assembly, including：Bearing block 3, thrust block 4, quilt
Dynamic roller is driven side bearing 7.
Referring to Fig. 2-Fig. 3, the end face of the bearing block 3 is provided with multiple oilholes 5.
The both sides of the thrust block 4 are respectively arranged with jet pipe 1, and the jet pipe 1 is just to oilhole 5.
The bearing block 3 is contacted with the thrust block 4 by axial limiting, and the bearing block 3 and driven roll are driven side axle
Hold 7 connections.
Used as a kind of optional embodiment, the driven roll transmission side bearing 7 and the bearing block 3 are fixed in two jointly
Between on driven roll 6 roll neck at.
Used as a kind of optional embodiment, the present invention have also been devised jet pipe 1 and nozzle 2 connects, and the nozzle 2 effectively covers
Capping is accumulated just to the oilhole 5.Preferably, the jet pipe 1 and the nozzle 2 are threadedly coupled.Preferably, the nozzle 2
For flat nozzle 2.
Present invention is primarily targeted at increasing emulsion jet pipe 1 dedicated for the driven roll transmission side axle on two centres
Hold 7 to be lubricated, because the surrounding space of the bearing in roller system is narrow and small, cause to lubricate jet pipe 1 and design there is difficult point.So will profit
Sliding jet pipe 1 is placed on from the aspect of the corresponding bearing block 3 of bearing, although and the end of bearing block 3 and the top of bearing block 3 have increase
The possibility of lubrication, but topside area is big, is easily affected and interference by peripheral equipment, increases jet pipe 1 difficult；Though and end
So area is little, but the passage that periphery has a very little may increase lubrication jet pipe 1, it is contemplated that the reliability and peace of newly-increased jet pipe 1
Quan Xing, the present invention selects to increase lubrication jet pipe 1, that is, the thrust block 4 contacted with the end of bearing block 3 in the end face of bearing block 3
Both sides increase respectively lubrication jet pipe 1, it is contemplated that the tolerance range of the passage of the end of bearing block 3, the present invention sets the external diameter of jet pipe 1
It is set to：8～10mm, preferred 9mm.Simultaneously in the newly-increased oilhole 5 in the end of bearing block 3, increase platypelloid type in the end of jet pipe 1 in addition
Nozzle 2, it is ensured that enough emulsion enters the inside of bearing block 3 and provides lubrication for bearing and cool down.
Further, since bearing block end is circle, bearing block oilhole exists with lubricating pipe relative position during installation
Uncertainty, therefore how circuit design and oilhole position of opening guarantee it is all the time unanimously another difficult point.
Specifically, the type selecting of the position of opening of oilhole 5, aperture and quantity and nozzle, setting angle are very crucial,
The position of opening (the hole distance of center circle bearing block center of circle is 50～60mm) of oilhole 5, aperture (10～20mm) and quantity (6-10),
These three numerical value may insure that oilhole 5 is not blocked by thrust block 4, and bearing block 3 has oilhole in the both sides of thrust block 4
5, then engagement nozzle pattern (platypelloid type, 15～30L/min of flow) and setting angle (parallel to thrust block), it can be ensured that foot
Enough emulsions enter the oilhole 5 of bearing block 3.
Therefore, when needing to be lubricated driven roll transmission side bearing 7, emulsion is sprayed to through the jet pipe 1
The end face of the bearing block 3, the emulsion enters described passive by the oilhole 5 that the end face of the bearing block 3 is arranged
Roller transmission side bearing 7 is lubricated.
