Description
Technical field
The utility model belongs to a kind of clutch that utilizes pneumatic element control pneumatic diaphragm to promote friction plate clutch.
Background technique
The diaphragm type axial air clutch adopts the oil resistant rubber folder to make the force application element of diaphragm as air pressure with artificial fiber, clamp the friction plate transmitting torque, principle is identical with piston type, but diaphragm is lighter than piston weight, inertia is little, and good airproof performance is active in one's movements, engage and disengagement time weak point, clutch shaft is to compact structure.Common diaphragm clutch friction portion is positioned at the cavity of belt wheel and inside and outside gland composition, heat dispersion is relatively poor, need dismantle many parts such as outer gland, bearing, sealing cover during installation, need by special tool, more also need carry out same dismounting again during easily damaged parts such as gentle film of renewal of facing renewal, quite loaded down with trivial details.Because part is more, the accumulation machining error is big, and partly there is the big phenomenon of swing in belt wheel.What the tension interlayer of pneumatic diaphragm adopted is canvas, and tensile strength is low, does not have amount of deformation, and working life is short.
Summary of the invention
The purpose of this utility model is that design is a kind of rational in infrastructure, compact, the new membrane chip axial air clutch of disengaging performance brilliance.
According to design proposal provided by the utility model, utilize the Bearing Installation hub at the middle part of belt wheel, ring gear is installed in end at belt wheel, the inwall of ring gear has internal spline, friction plate is arranged in ring gear, external splines in the outer rim setting of friction plate and the engagement of the internal spline on the ring gear, between adjacent two friction plates, telophragma is arranged, the inwall of telophragma has internal spline, the tooth axle is arranged in telophragma, external splines in the internal spline engagement of the outer rim setting of tooth axle and telophragma, the internal tooth advance and retreat disk that has and can be in contact with one another in the left side of friction plate, the right side of friction plate can contact with the left side of hub, sealing cover is installed in left side at the tooth axle, between the right side of sealing cover and internal tooth advance and retreat disk, the air film that is installed on the sealing cover is arranged, between air film and sealing cover, form air chamber, the suction port that is communicated with air chamber is set on sealing cover, the guide pillar of the parallel axes of installation and tooth axle on hub, sleeve spring seat on guide pillar, the spring that is enclosed within on the guide pillar is arranged between spring seat and hub, and the outer rim left side of spring seat can contact with the right side of internal tooth advance and retreat disk.
With the position that inner edge is connected with sealing cover respectively the outer gland of air film of annular and the air film internal gland of annular are arranged in the outer rim of air film, the outer gland of the air film of air film utilization annular is installed on the sealing cover with annular air film internal gland.Air film is pressed from both sides with the compression moulding of Polyamide Yarns cloth by nitrile rubber.Left end at sealing cover connects the air guide joint, utilizes pipeline to be interconnected between the suction port on air guide joint and the sealing cover.
The utility model has the advantages that the clutch with clutch partly moves to the belt wheel outside, belt wheel by Bearing Installation on hub, reduce the processing accumulated error, the belt wheel swing is little, when installing, clutch only need dismantle the air guide joint, can with the clutch integral installation on the working machine input shaft, also only need dismounting air guide joint and sealing cover, easy accessibility when changing easily damaged parts.Clutch is partly exposed, and radiating effect is better outside, has prolonged the working life of clutch part, and the gas-entered passageway that air guide joint and pipeline are formed is quick for installation, leaks little.Newly-designed air film 4 changes the material of stretch-resisting layer into Polyamide Yarns cloth, has increased the tensile strength and the amount of deformation of air film, has prolonged the working life of diaphragm, has increased friction plate abrasion compensation rate.The air chamber that diaphragm and metallic sealed cover are formed is positioned at the clutch outermost.
