Abstract
The utility model relates to a decelerating clutch for a brushless motor directly driven washing machine. The problems of limited speed control, high noise, large power consumption, and unavailable centrifugal type washing function exist on the transmission mode of combining a single-phase asynchronous motor and a pulley, which are on the input shaft of a decelerating clutch for a washing machine. The utility model solves the problems. The utility model is mainly characterized in that a permanent magnetic outer rotor brushless direct current motor is installed directly and coaxially on a transmission moment shaft sleeve of the clutch input shaft, and is fixed on the housing of the clutch; a brushless motor shaft is also a clutch transmission moment shaft. The utility model has the advantages of speed control, noise reduction and energy saving. The pulley transmission mode is eliminated, the clutch is more compact, and meanwhile, the clutch can adapt to washing function requirement.
Description
The utility model relates to the decelerating clutch of washing machine that important accessory, particularly brushless electric machine directly drive on the washing machine.
Clutch coupling of washing machine in the past generally has impeller deceleration device, dehydration transmission device, ratchet mechanism and braking draw-gear and is installed on the base of rectangle plate-like.And belt pulley is installed on the power shaft, belt pulley is in transmission connection with motor output shaft again.This monopole asynchronous motor adds the upper belt pulley kind of drive and exists speed control restricted, and noise ratio is bigger, and power consumption is many, especially can only realize the impeller washing.Then in speed control, be restricted for more advanced centrifugal washing, can't realize the requirement of centrifugal washing for motor speed control owing to monopole asynchronous motor adds belt pulley.
The purpose of this utility model provides the decelerating clutch of washing machine that a kind of brushless electric machine directly drives.Superseded asynchronous motor adds pulley transmission structure, realizes centrifugal washing function, improves the washing machine class
The technical solution of the utility model is that brushless motor stator shell (9) is installed on the clutch housing (24), and electricity is placed in the stator casing (9), and is fastenedly connected with clutch housing (24); Motor stator (11) is installed Clutch input shaft combination (14) with the hollow space of shell (9), and the outer torque transmissioning shaft cover (15) that is equipped with of Clutch input shaft combination (14); Rotor is housing (13), and housing (13) is inboard to be equipped with permanent magnetic steel (12) with the corresponding position of stator (11), constitutes the motor permanent-magnetic outer rotor; Housing (13) is fastenedly connected with passing square sheet (17), and is fastenedly connected with torque transmissioning shaft cover (15), and making the brushless electric machine axle is again the clutch torque transmissioning shaft, the diaxon unification.Brushless electric machine has also just become permanent-magnetic outer rotor two phase brushless DC motors.
Said brshless DC motor can also be three-phase or heterogeneous structure.
The utility model has the advantages that the control of 1. realization speed, noise reduction sound energy-conservation again (with respect to induction conductivity); 2. eliminate the belt pulley transmission, save assembly space, make clutch miniaturization more; 3. structure is compact more, realizes electromechanical integration; 4. can make washing machine realize centrifuge washing, increase function.
Further specify embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structure chart of the present utility model.
With reference to Fig. 1, this practical structure is by constituting as lower member: 1 braked wheel, 2 brake arm pins, 3 brake ribbons, 4 unilateral bearings, 5 brake arms, 6 pawl arm, 7 rolling bearings, 8 pawl arm springs, 9 motor stator shells, 10 motor stator fixing threaded holes, 11 motor stators, 12 permanent magnetic steels, 13 rotor shells, the combination of 14 power shafts, 15 torque transmissioning shaft covers, 16 nut shims, 17 pass the square sheet, 18 needle bearings, 19 bearing chambers, spring is robbed in 20 clutches, 21 ratchets, 22 oiliness bearings, 23 case lid, 24 clutch housings, 25 planet circular systems, the combination of 26 output shafts, 27 bases, 28 big water seals, the combination of 29 dehydrating shafts.
What the utility model was different with decelerating clutch of washing machine in the past is: eliminate and to continue to use monopole asynchronous motor always and add the input power of upper belt pulley as clutch, adopt brshless DC motor to be directly installed on the power shaft of clutch, the output shaft of motor is the power shaft of clutch just.The concrete practice is: brushless DC motor stator shell (9) is installed on the clutch housing (24), motor stator (11) is placed in the stator casing (9), and be fastenedly connected with clutch housing (24), stator (11) is installed Clutch input shaft combination (14) with the hollow space of shell (9), the outer torque transmissioning shaft cover (15) of installing of power shaft combination (14).Rotor that is to say housing (13).Housing (13) is inboard to be equipped with permanent magnetic steel (12) with the corresponding position of stator (11); Housing (13) is fastenedly connected with biography square sheet (17).Making the brushless electric machine axle like this is again the clutch torque transmissioning shaft.This brushless electric machine is permanent-magnetic outer rotor two phase brushless DC motors, also can become three-phase or heterogeneous structure by changing the stator winding wiring.
Adopt direct-drive type axial magnetic field brush-less permanent magnetic direct current generator, this kind motor rated power 300W, rotating speed can select to regulate in 100～1200 rev/mins, and the torque characteristics during its high low-speed running is better, can adapt to the multi-functional requirement of clutch fully.Its rotating frequency can be selected by computer control on demand simultaneously.This motor directly coaxial torque transmissioning shaft that is installed in Clutch input shaft puts.And be fixed in clutch outer member body bearing-surface positioning disk on, save belt pulley, can guarantee axiality again, reduce the radial force of axle and wearing and tearing to bearing.
Said impeller deceleration device comprises in the utility model: power shaft combination (14), torque transmissioning shaft cover (15), planet circular system (25); Said dehydration transmission device comprises: output shaft combination (26), big water seal (28) and dehydrating shaft combination (29); Said ratchet mechanism comprises: pawl arm (6), pawl arm spring (8), ratchet (21); Said braking draw-gear comprises: braked wheel (1), brake arm pin (2), brake ribbon (3), unilateral bearing (4), brake arm (5) etc.
