Description
(1) technical field:
The utility model relates to a kind of clutch, is a kind of magnetic surface engaging clutch specifically.Be applicable to (going straight up to) aircraft and steamer.
(2) background technique:
On the drive path of traditional mechanical friction clutch extensive use and Motor Vehicle, (going straight up to) aircraft, steamer etc.; Its objective is the main transmission of motor is transmitted to gearbox; In the gearshift procedure of gearbox; The effect of friction clutch is exactly the power that cuts off between gearbox and the main transmission, to realize switching smoothly fast gear.Friction clutch commonly used is made up of Flywheel disc, fixed tray, platen and friction plate etc.; Flywheel disc is connected with fixed tray is coaxial; The external engine output shaft of Flywheel disc axle; Platen moves axially with fixed tray is concentric relatively and with respect to the output shaft of fixed tray along gearbox, and what arrange between platen and the fixed tray is the friction plate of concentric.When platen when fixed tray compresses, when just friction clutch combined, friction plate passed to gearbox through frictional force with the driving force of motor; When platen leaves fixed tray; Loosen the compressing of friction plate, when promptly friction clutch separated, the transmission of power of motor was blocked by friction plate.
Mechanical friction clutch is simple in structure, low price, easy to use, and easy operating is inexpensive really; But owing to be the frictionally transferring power, there is it not open the defective of avoidance again, when driving torque uses greatly or for a long time; Wearing and tearing can occur between fixed tray and the friction plate, between platen and the friction plate, cause and skid, influence normal transmission of power; Therefore to adjust or renewal of facing renewal more friction clutch aperiodically; See that from this angle mechanical friction clutch exists working life short, safeguards inconvenient shortcoming.
(3) model utility content:
To the deficiency of above-mentioned mechanical friction clutch, the utility model purpose has provided a kind of closely non-slip magnetic surface engaging clutch that combines, and the utility model also has antiwear function.
Can realize the magnetic surface engaging clutch of above-mentioned purpose; Comprise fixed tray; Combine and the Effector that separates with fixed tray along output shaft of gear-box with the control platen with the coaxial platen of facing of fixed tray; Different is: the utility model has been cancelled the friction plate of conventional clutch, and fixed tray and platen opposing end faces are provided with intermeshing engaging tooth and engaging groove, realizes that through engaging tooth and engaging groove fixed tray is directly to the platen transmitting torque; Because adopt engagement driving, fixed tray is called the fixed engagement dish in the utility model, platen is called movable mesh plate.
The engagement of fixed engagement dish and movable mesh plate is in the slow rotation process of motor, to accomplish; Therefore to be with mesh plate end face center be the fan shape in the center of circle for engaging tooth and engaging groove; Protruding on the fixed engagement dish engaging tooth or be depressed in the engaging groove of fixed engagement dish, have identical five equilibrium with engaging groove or the engaging tooth that is raised in movable mesh plate on being recessed in movable mesh plate.
The height of engaging tooth is identical with the degree of depth of engaging groove.
The axle head of output shaft is provided with the locating stud of concentric, and locating stud cooperates with the positioning hole at fixed engagement dish end face center, and accurate positioning when being beneficial to install guarantees successfully to combine and meshes closely.
It can be mechanical handling, hydraulic operation or other mode that can realize that the fixed engagement dish combines with the Effector that separates with movable mesh plate, and engaging tooth contacts with the engaging groove rigidity in these are handled, and can cause wearing and tearing to a great extent.
After deliberation; Preferably adopt control circuit that the combination of fixed engagement dish and movable mesh plate is handled with separating, fixed engagement dish and the movable mesh plate of this moment must be steel materials, the coaxial coil that is wound with on fixed engagement dish and the movable mesh plate; Control circuit is made up of necessary electrical apparatus element; Control circuit is connected with the coil of fixed engagement dish and movable mesh plate, changes the magnetic of fixed engagement dish and movable mesh plate junction plane, makes it to be same sex magnetic or different in nature magnetic; The fixed engagement dish repels mutually with movable mesh plate and separates during same sex magnetic; The fixed engagement dish attracts to combine with movable mesh plate mutually during opposite sex magnetic, and in engagement process, the engaging tooth that has magnetic can prevent wearing and tearing effectively with engaging groove in rigidity contacts.
A kind of simple and practical control circuit comprises battery main switch, separating switch, adhesive switch and has the contactor of many group sound contact.When contactor is switched on; Movable contact is connected and the stationary contact disconnection; When contactor cut off the power supply, stationary contact was connected and the movable contact disconnection, so pass through the combination of separating switch, the different break-make modes with contactor of adhesive switch; And the electric current of realizing fixed engagement dish coil and movable mesh plate coil is identical or opposite, on the engagement end face, produces homopolarity that repels mutually or the heteropole that attracts mutually with this.
Because the rotation of fixed engagement dish coil and movable mesh plate coil; Thereby fixing control circuit also must could reliably be connected with movable mesh plate coil with fixed engagement dish coil through some conversion equipments; Conversion equipment commonly used is carbon brush and coil slip ring; The coil slip ring separates limit into two in the centre by dead ring; The coil slip ring is fixedly sleeved on the coil of fixed engagement dish and movable mesh plate, and two rear line heads of each coil are separately fixed on the two halves of corresponding coil slip ring, and two pairs of carbon brush are installed on the carbon brush holder; Sliding contact is on each one side of something of corresponding coil slip ring respectively for one end of every pair of carbon brush, and the other end of every pair of carbon brush inserts on the sound contact corresponding in the contactor through lead.
Movable mesh plate fixed distance mesh plate after might separating is too far away; The adhesive scope that has exceeded both; Can be on the output shaft behind the movable mesh plate the coaxial thrust pad that is fixed with, the movable mesh plate that exceeds distance range is stopped, make both keep the size of separation of setting.Can also on thrust pad, install auxiliary separate winding additional and for example install the separation ancillary coil additional, hold the movable mesh plate after the separation, prevent to separate not thorough.
The advantage of the utility model: the utility model engaging clutch has been cancelled traditional friction plate; And replace mechanical handling movable mesh plate fixed distance mesh plate to be separated and engagement with control circuit; Engagement is to rely on engaging tooth and the engaging groove transmitting torque that is provided with on the junction plane of movable mesh plate, fixed engagement dish; Therefore handiness, simple in structure, combine reliability high, overcome be prone to when using friction plate to skid, defective easy to wear.
