Description
Technical field
The present invention relates to a kind of pneumatic clutch.
Background technique
Pneumatic clutch is a mechanism commonly used in the existing machinery, can be divided into piston type, diaphragm type, pneumatic tyre formula by the air cylinder structure form, and wherein the piston type pneumatic dynamic clutch can be made a plurality of friction surfaces according to the moment of torsion needs, is highly suitable for the big machinery of transmitting torque.
Piston type pneumatic dynamic clutch technology is constantly weeded out the old and bring forth the new at present, as " annular piston formula pneumatic clutch ", " a kind of piston type pneumatic dynamic clutch ", " brake type pneumatic clutch ", " axial air clutch ", " cylinder type axial air clutch ", many patented technologies such as " pneumatic clutches ", developed the technology of piston type pneumatic dynamic clutch, but the power output structure of existing piston type pneumatic dynamic clutch is also simpler and easy, generally all directly adopt belt wheel, and simple bearing structure is also all adopted in the way of contact of belt wheel and power input shaft, have nothing to fear fully for general mechanical transmission like this, it is many then to have problems concerning the machinery that mechanical transmission influence of vibration is had relatively high expectations, though adopted the belt wheel of band flywheel in " brake type pneumatic clutch " patented technology, this structure only can overcome less mechanical transmission vibration, can not satisfy the transmission demand of precision optical machinery fully.
Summary of the invention
The invention provides a kind of air operated friction clutch, it has overcome the vibration in self machine operation process, and volume is little, transmitting torque is big, be applied among the powder metallurgy machinery.
The present invention is achieved in that air operated friction clutch comprises power input mechanism, power take-off mechanism, pneumatic mechanism, specifically: fixing gear ring (2) on the flywheel-type belt wheel (1), be gear ring (2) by screw on the groove of flywheel-type belt wheel (1), platen seat (7) is placed in the concave surface of flywheel-type belt wheel (1), the internal spline of gear ring (2) is being united wearing piece (3), can adorn many group wearing pieces (3) (diagram is only united one group of wearing piece) on the internal spline of gear ring (2), quiet inner blade (4) in the middle embedding of every group of wearing piece (3), quiet inner blade (4) is united with the external splines of platen seat (7), the rear portion of platen seat (7) is connecting pneumatic mechanism, fixing by locking nut (9), stage clip (10) is embedded between piston (5) end face in platen seat (7) and the pneumatic mechanism; Piston (5) in the pneumatic mechanism is contained in the cylinder body (6) simultaneously, and piston (5) is provided with oil sealing (11) with the contacting point of cylinder body (6), and gas-tpe fitting seat (8) is inserted in platen seat (7) the afterbody endoporus, and is fastening by screw; Secondly cylinder body (6) outside in the pneumatic mechanism is provided with braking vane assembly (12); In the center hole of flywheel-type belt wheel (1) 2 bearing pack (13) are being set once more, bearing spacer (14) in embedding between each bearing pack (13), bearing pack (13) is made up of 2 deep groove ball bearings, and pto (15) was gone here and there 2 bearing pack (13) and is fastened in the anterior endoporus of platen seat (7).During work, source of the gas enters in the cylinder body (6) by gas-tpe fitting seat (8), promote piston (5) end face of wearing piece (3) and the end face of quiet inner blade (4) are compressed, this moment, clutch was tending towards clutch state, pto (15) and the running of flywheel-type belt wheel (1) concentric; Otherwise, close source of the gas, piston (5) return under the effect of stage clip (10), the end face of wearing piece (3) separates with the end face of quiet inner blade (4), and this moment, clutch was tending towards separated state, and flywheel-type belt wheel (1) shuts down.
Effect of the present invention is that this clutch operation links up steadily, and volume is little, transmitting torque is big, can satisfy the transmission demand of precision optical machinery.
