Abstract
The utility model relates to a clutch driven by the fluid power of the dynamic axis, which is used in a spindle box of a lathe. The utility model is characterized in that the utility model adopts the structure that an annular oil cylinder 5 is utilized to press active and passive friction plates 4 in liquid to replace the structure that a coil of an electromagnetic clutch used in the existing lathe is utilized to electromagnetically attract the friction plate, as well as adopts the dual thrust bearing structure to replace the radial bearing structure. The utility model has the advantages of compact structure, reasonable stress, large clutching force and high transmission efficiency, so the utility model can be used in the field of the mechanism device and is especially applicable to rebuild the existing lathe clutch.
Description
The utility model relates to a kind of friction surface that has that is mainly used in Lathe Spindle Box medium power axle, and wherein piston, this piston of being contained in the clutch of one of liquid driven do not drive clutch with the fluid power that clutching member rotates.
86203432 " Wet-type multi-disc friction-type electromagnetic clutch " a kind of application number disclosed in the Chinese patent communique on September 2nd, 1 is.Its purpose is to simplify general clutch configuration and reduce cost and improve working life.Formation is that the yoke body and three that adopts iron-core coil, yoke iron core to replace in the general clutch encircles baffle plates and suitably changed bearing support structure.Its deficiency is in using on lathe; when the big torque of needs transmission is full depth; since electromagnetic clutch power restriction make clutching member produce carrying relatively friction and line shaft certain idle running appears, thereby the clutching member wearing and tearing very easily take place or coil burnout causes shutdown maintenance and clutch to scrap.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of torque transfer capability high lathe hydraulic coupling.
The purpose of this utility model is by improving with magnetic clutch at existing lathe, promptly mainly having adopted the pressing of oil cylinder liquid to replace structures such as coil electromagnetism adhesive and the supporting of clutch employing thrust-bearing replacement radial bearing and realized.Concrete structure of the present utility model comprises that assemble at the interval on block bearing between bearing sleeve in the existing clutch, driving shaft spline gear cover, bearing sleeve internal diameter and the geared sleeve external diameter that internal diameter cooperates with driving shaft, the geared sleeve gear ring can lead in axial sliding, clutch actuator and the interlock between axial of driven friction, bearing sleeve and friction plate, pass surely, reset and fastening structure etc.Specialization of the present utility model be the clutch actuator of clutch be its ring-type axis of being provided with in the bearing sleeve with the ring-type oil cylinder of geared sleeve dead in line, in-oil cylinder annular piston structure, corresponding ring-type oil cylinder be bearing sleeve with friction plate between the end that is provided with contact with the piston structure end face, internal diameter forms with the thrust-bearing that the bearing sleeve crest clearance cooperates.The annular metal piston pressure pad that contacts with aforementioned thrust-bearing end face that described piston structure is provided with the piston ring outer end by V-ring shape rubber piston circle is formed.Specialization of the present utility model is that also thrust-bearing and the friction plate in clutch actuator is provided with that two ends contact with the friction plate end face with aforementioned thrust-bearing respectively, the axial pressing plate of internal tooth casing that cooperates with the gear ring of geared sleeve of internal tooth radially between axially.At axial pressing plate and be fixed on the geared sleeve end and be used for being provided with the clutch actuator Returnning spring in the geared sleeve between the baffle plate of, pressure-bearing spacing to the friction plate the other end.Specialization of the present utility model is that also the block bearing between bearing sleeve and the geared sleeve is can be by the thrust-bearing of nut pretension location.
Accompanying drawing is the utility model specific embodiment structure cross-sectional schematic.
Shown in the accompanying drawing, driving shaft 16 is the cantilever splined shaft.Bearing sleeve 1 is limit its rotation by the block on the headstock gusset or locating stud and other position structure.Be by thrust ball bearing 3 supportings between the external diameter of the spline gear cover 2 that cooperates on the splined shaft of driving shaft 16 and the internal diameter of bearing sleeve 1.Bearing 3 is spacing by nut 10 pretensions of installing on the geared sleeve 2 left end major diameter of threads.10 on nut blocks 14 surely by pin and locks.Geared sleeve 2 right-hand members connect a plate-like baffle plate 11 by screw.The left side of baffle plate 11 is equipped with main, driven friction 4, the internal diameter gear ring of the active friction plate that it assembles at interval and the engagement of the external diameter gear ring of geared sleeve 2, and the external diameter end of its driven friction is by coupling sleeve 15 and passive axle sleeve 17 interlocks.The left end of friction plate 4 is equipped with that its right side contacts with the friction plate left side, the axial pressing plate 9 of internal tooth casing of the external toothing engagement of its internal diameter gear ring and geared sleeve 2.On the gear wall of geared sleeve 2, be provided with through hole, right-hand member be housed in the through hole contact, the Returnning spring 12 that left end contacts with the Kong Tai right side of pressing plate 9 with baffle plate 11 left sides.The shaft shoulder face of bearing sleeve 1 is provided with ring-type oil cylinder 5, and the oil-feed interface 13 of oil cylinder 5 is arranged on the outer side surface of bearing sleeve 1.V-ring shape rubber piston circle 7 is housed in the oil cylinder 5, and the right-hand member of piston ring 7 is equipped with annular metal piston pressure pad 8.Between the left side of the right side of piston pressure pad 8 and pressing plate 9 thrust ball bearing 6 that internal diameter cooperates with the crest clearance of bearing sleeve 1 is installed.
The utility model has following advantage compared to existing technology:
1. compact conformation, strong adaptability are particularly useful for transforming existing lathe clutch.
2. stressed rationally, clutch is reliable, reduce friction damage zero clutch parts and improve working life.
3. hydraulic driving, clutching force are big, and improve lathe manufacturing efficiency.
4. the dual thrust ball bearing overcomes the inner axial force of clutch, and it is little and improve the rotational efficienty of clutch to rotate power-assisted.
