Definitions
- This invention relates to a method for fixing to a washing machine tub the electric motor which drives the drum positioned in the tub.
- the invention also relates to the resultant washing machine.
- Various methods are used for fixing the motor to the tub.
- the motor is fixed to the spider structure which supports the tub.
- One of the spider arms is used as a fixing support for the motor.
- the motor bearing plate at the motor drive end carries an arm provided with a pin mounted in such a manner as to be able to rotate within the spider arm via a rubber/metal bush.
- the arm carried by the plate is fixed to the spider arm by a screw means positioned in an arcuate slot in correspondence with the bearing plate. This arrangement is supposed to facilitate motor assembly. It is however complicated, it seriously stresses the mechanical parts and does not adequately exclude vibration or noise.
- the motor bearing plates are provided with pins which are inserted via nylon bushes into holes present in appendices on the tub. This known arrangement does not allow take-up of slack, nor does it eliminate vibration and noise.
- a further arrangement which has the advantage of nullifying slack and eliminating noise and vibration is however particularly complex in that fixing is by bolts inserted through two stop washers, a rigid spacer, a rubber damping block and a tightening nut.
- the main object of the present invention is to provide a fixing method which besides being considerably simpler than the known methods enables slack, noise and vibration to be eliminated.
- a further object of the present invention is to provide a washing machine comprising a motor fixed by the method of the invention.
- washing machines comprise a tub 3, a clothes drum 5 rotatably supported within the tub 3, an electric motor 10 supported by the tub, and a transmission comprising a belt 4a and pulleys 4 for transmitting motion from the motor to the drum 5.
- a transmission comprising a belt 4a and pulleys 4 for transmitting motion from the motor to the drum 5.
- the motor When in this angular position the motor is locked by a nut and a bolt which passes through both an arcuate slot and a cylindrical hole, one for example in a part of the tub and the other in a part of the motor.
- the said geometrical axis 1 pertains to two spaced-apart coaxial pins projecting in the same direction and integral with the tub 3, which as is well known is constructed of a filled synthetic material.
- a coating 11 of silicone rubber in the pasty state is applied to said coaxial pins 2.
- This application is achieved by injection using a conventional dispensing gun, not shown, the exit of which is connected to a tube 20 having its end mounted on a tubular appendix of a distributor indicated overall by 22.
- the distributor 22 comprises a tubular cylindrical part 23 closed at one end and open at the opposite end.
- the inner diameter of the part 23 exceeds that of the pin 2 by twice the thickness of the coating 11.
- a disc 24 of synthetic material such as teflon which defines the inner length (L) of the tubular part 23.
- the distributor is mounted on the pins 2 as shown in Figure 2 and is removed after the application.
- Corresponding eyelets 7 provided on the bearing plates 8, 9 of the electric motor 10 are mounted on the thus coated coaxial pins 2, the motor axis being indicated by 13 and being parallel to the axis 1 of the pins 2.
- the silicone rubber passes from the pasty state to the rubbery state without volume change, to form an intermediate layer between the pins 2 and the eyelets 7 which adheres securely to the pins 2, to nullify slack and eliminate vibration and noise in a simple and effective manner.
- the invention also includes an embodiment in which the eyelets 7 are provided with a dead hole instead of a through hole.
