Description

Structure for improving noise of oil-retaining bearing motor

Technical Field

The utility model relates to an oil-retaining bearing motor, in particular to a structure for improving the noise of the oil-retaining bearing motor.

Background

In recent years, with the continuous expansion and expansion of the market of household appliances, motor products are used as important accessories of the whole machine, and the motor products have larger and wider application fields and wider application. The motor with the oil-retaining bearing structure is also commonly applied to the field of electric products such as rolling doors and the like. Manufacturers in the industry select oil-containing bearings in a lot for reducing the production cost, and the oil-containing bearing motor tends to replace a ball bearing motor;

however, certain tolerance exists in manufacturing, so that the zero matching of the oil-containing bearing in the oil-containing bearing motor and the rotating shaft cannot be realized, and the effect of the ball bearing cannot be achieved, therefore, when the motor is transversely placed or inclined, the rotor can be slightly inclined due to the self gravity, so that the rotating shaft is eccentric, and abnormal sound is generated when the motor runs due to friction generated by eccentricity after the rotating shaft is eccentric, so that the noise decibel is increased; therefore, a structure for improving the noise of the oil-retaining bearing motor is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provides a structure for improving the noise of an oil bearing motor.

In order to achieve the purpose, the utility model provides a structure for improving the noise of an oil bearing motor, which comprises a motor shell, a turbine shell connected with the motor shell, a rotating shaft movably arranged in the motor shell and the turbine shell, and a rotor arranged on the rotating shaft; one end of the rotor is provided with an oil bearing; it is characterized by also comprising an elastic pad which is arranged between the rotating shaft and the motor shell and is used for improving noise.

Further preferably, the motor housing is provided with a rear end cover, the rear end cover is provided with a limiting concave table for limiting the position of the elastic pad, and the elastic pad is installed in the limiting concave table and one end of the elastic pad is in contact with one end of the rotating shaft.

Further preferably, a boss is arranged on one side of the elastic pad contacting with the end of the rotating shaft.

Further preferably, the elastic pad is made of rubber or silica gel.

The elastic pad is arranged between one end of the rotating shaft and the rear end cover, and the rotating shaft is propped against the elastic pad, so that abnormal sound caused by the fact that the rotating shaft generates certain eccentricity due to self gravity when the motor inclines is prevented, noise generated when the motor is used is reduced, and meanwhile, the noise generated when the rotating shaft rotates can be absorbed by the elastic pad and then transmitted out, and certain noise is further reduced;

the position of the elastic pad is limited by the arrangement of the limiting concave table, so that the phenomenon that the noise reduction effect cannot be achieved due to deviation between the position and the end position of the rotating shaft during installation is avoided;

through set up the boss on the cushion, withstand pivot tip through the boss, withstand the pivot and reduce the area of contact with pivot tip when preventing its slope, avoid area of contact too big and lead to the idle current of motor too big.

Detailed Description

The structure for improving the noise of the oil-retaining bearing motor according to the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-3, a structure for improving noise of an oil-retaining bearing motor includes a motor housing 1, a turbine housing 2 connected to the motor housing 1 through a screw thread, a rotating shaft 3 movably installed in the motor housing 1 and the turbine housing 2, and a rotor 4 installed on the rotating shaft 3; one end of the rotor 4 is provided with an oil bearing 5; the motor is characterized by also comprising an elastic pad 6 which is arranged between the rotating shaft 3 and the motor shell 1 through extrusion and is used for improving noise; through installation cushion 6 between 3 one ends of pivot and rear end housing 11, withstand pivot 3 through cushion 6, pivot 3 produces certain slope and leads to the noise too big because self gravity when preventing the motor slope to reduce the noise that the motor produced when using, the noise part that produces when pivot 3 rotates simultaneously can also wear out through cushion 6, thereby reduces certain noise.

Further, an integrally formed rear end cover 11 is arranged on the motor shell 1, a limiting concave table 12 for limiting the position of the elastic pad 6 is arranged on the rear end cover 11, the elastic pad is movably arranged in the limiting concave table 12, and one end of the elastic pad is in contact with one end of the rotating shaft 3; through the setting of spacing concave station 12, carry on spacingly to the position of cushion 6, the position produces the deviation with the 3 tip positions of pivot and can't play the effect of making an uproar when avoiding installing.

Further, a boss 61 is arranged on one side of the elastic pad 6, which is contacted with the end part of the rotating shaft 3; through set up boss 61 on cushion 6, withstand pivot 3 tip through boss 61, withstand pivot 3 and reduce the area of contact with pivot 3 tip when preventing its slope, avoid area of contact too big and lead to the idle current of motor too big.

Further, the elastic pad 6 is made of rubber or silica gel, so that the elastic pad 6 has certain elasticity and certain reset force after extrusion, and can be propped against one end of the rotating shaft 3.

The installation process of the utility model is as follows: insert in turbine shell 2 with turbine shell 2 swing joint at first 3 one ends of pivot, then install oiliness bearing 5 in pivot 3, install elastic pad 6 and carry on spacingly to its position in spacing concave station 12 of rear end cap 11 again, then pass through screw thread and turbine shell 2 fixed connection with motor housing 1, after the connection is accomplished, the tip of pivot 3 of installing the one end of oiliness bearing 5 forms the extrusion to boss 61 on elastic pad 6, elastic pad 6 withstands pivot 3 through self and the elasticity that self has when fixed mounting between pivot 3 and rear end cap 11 to the extrusion that it formed through pivot 3 and rear end cap 11, spacing is carried out to pivot 3 position, prevent that it from producing the slope.
