The purpose of the utility model realizes through following technical scheme:
The fixed three sword hobboing cutters of a kind of end cap of belt wear deixis; Include a rotating shaft cross-under three sword hobboing cutters cutter hub and be arranged on end cap that the cutter hub both sides are used for fixing and cutter hub in the bearing that is provided with; An inner chamber that is communicated to each blade from roller end is set on the said cutter hub; Said inner chamber connects fuel transfer system, and said fuel transfer system is connected with pressure meter or pressure sensor.
Preferably, said inner chamber comprises that one is arranged on the rotating shaft center and along the horizontal main line of shaft axis direction, said horizontal main line is connected with three vertical branch roads that are communicated to blade.
Preferably; Annular solid of the outside socket of said rotating shaft can relatively rotate between its two, and said annular solid is arranged on the centre position of hobboing cutter; The place, mating face of said annular solid and rotating shaft is provided with dynamic seal; Said annular solid and cutter hub joint are provided with the O RunddichtringO, and said blade and cutter hub junction also are provided with the O RunddichtringO, lock through key between said annular solid and the cutter hub.
Preferably, the blade place on the said cutter hub is provided with the oil transportation hole of the abrasion condition that can survey blade different parts on circumference.
Preferably, be placed with needle bearing between said annular solid and the bearing.
The beneficial effect of the utility model is: because said three sword hobboing cutters are provided with a connection fuel transfer system that is communicated to the inner chamber of each blade from roller end; Said fuel transfer system is provided with pressure meter or pressure sensor, can find out the three sword hobboing cutters that worn and torn accurately; Again because inner chamber comprises that one is arranged on the rotating shaft center and along the horizontal main line of shaft axis direction; Said horizontal main line is connected with three vertical branch roads that are communicated to blade; Blade place on the cutter hub is provided with the oil transportation hole of the abrasion condition that can survey blade different parts on circumference; So not only can in time find out damaged hobboing cutter, the position of the blade that can also accurately confirm to be worn.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model.
Among the figure:
1, blade; 2, cutter hub; 3, bearing; 4, rotating shaft; 5, end cap; 6, horizontal main line; 7, vertical branch road; 8, union; 9, fuel transfer system; 10, pressure meter or pressure sensor; 11, annular solid; 12, dynamic seal; 13, O RunddichtringO; 14, key; 15, oil transportation hole; 16, the annular oil groove on the cutter hub; 17, the annular oil groove in the rotating shaft; 18, bolt; 19, needle bearing.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment; As shown in Figure 1; In present embodiment; The fixed three sword hobboing cutters of a kind of end cap of belt wear deixis, include rotating shaft 4 cross-under three sword hobboing cutters cutter hub 2 and be arranged on end cap 5 that cutter hub 2 both sides are used for fixing and cutter hub 2 in the bearing 3 that all is provided with, an inner chamber that is communicated to each blade 1 from rotating shaft 4 ends is set on the cutter hub 2; Inner chamber connects fuel transfer system 9; Fuel transfer system 9 is connected with pressure meter or pressure sensor 10, and inner chamber comprises a horizontal main line 7 that is arranged on rotating shaft 4 centers and arranges along the shaft axis direction, and horizontal main line 7 is provided with three vertical branch roads 6 that are communicated to blade; Be respectively arranged with annular oil groove 16 in cutter hub 2 and the rotating shaft 4, be provided with a plurality of oil transportations hole 15 in the blade 1, and be connected with the annular oil grooves 16 of setting in the cutter hub 2; Vertically branch road 6 is connected with the annular oil groove 18 of setting in the rotating shaft 4, and fuel transfer system 9 makes horizontal main line 7 of oily arrival and vertical branch road 6 through union 8, when do not wear and tear in blade 1 place; Can be well with oil seal in inner chamber; When wearing and tearing appearred in blade 1 place, the leakage of oil situation will appear in hobboing cutter, because blade 1 inside has plural oil transportation hole; Can directly learn the abrasion condition of different parts on blade 1 circumference; Fuel transfer system 9 is provided with pressure meter or pressure sensor 10, and blade 1 place on the cutter hub 2 is provided with the oil transportation hole 15 of the abrasion condition that can survey blade 1 different parts on circumference, when wearing and tearing appear in blade 1 place; The leakage of oil situation will appear in hobboing cutter; Cause the variation of pressure meter or pressure sensor 10 simultaneously, operating personnel's variation of chamber pressure that can visually see, thus find out the three sword hobboing cutters that worn and torn accurately.
