Abstract

The utility model discloses a self-aligning support for fixing the spindle of a low-power motor. The self-aligning support comprises a support (1). A through hole is formed at the axis position of the support. An abacus bead-like bush (2) which can be sleeved onto the motor spindle (5) is arranged in the through hole. The outside of the bush is coated with an oil cotton ring (4). The self-aligning support further comprises a gland (3) for pressing the bush into the through hole. A first step, a second step and a third step which are joined successively are formed on the inner wall of the through hole, wherein the diameter of the first step, the diameter of the second step and the diameter of the third step are in ascending order. The sidewall of the first step forms a circular cone for bearing the bush. The sidewall of the second step forms a cylinder for placing the oil cotton ring. The sidewall of the third step forms a cylinder for clamping the gland. The bush is pressed onto the first step through the gland. Compared with the prior art, the self-aligning support of the utility model has advantages of small contact surface, less frictional resistance, easy lubrication, less abrasion, quick self-aligning speed and broad market prospects.

Description

The aligning support of a kind of fixedly low-power machine rotating shaft

Technical field

The utility model relates to motor, relates in particular to the aligning support of a kind of fixedly low-power machine rotating shaft.

Background technology

At present, fixedly the aligning support of low-power machine rotating shaft generally adopts ball cup scholar structure, and aligning support mainly comprises with the support of the fixing hollow of motor, is enclosed within the ball cup scholar of profile in the rotating shaft such as abacus bead, cotton, and fixing ball cup scholar's the gland of oil that plays lubricated rotating shaft; The center of support is dome shape, and ball cup scholar and support are sphere-contacts.The advantage of this structure is: machine shaft can automatic aligning, makes that to manufacture low-power motor more simple, and production technology can better be controlled; But its defective is: contact area causes greatly frictional resistance large, and motor is aligning faster, and contact area causes greatly lubrication oil circulation to be obstructed, and has increased wearing and tearing.

The utility model content

The utility model is the problems referred to above that will solve prior art, propose a kind of frictional resistance little, easy to lubricate, wearing and tearing little, the fireballing aligning support of aligning.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is the aligning support of a kind of fixedly low-power machine of design rotating shaft, comprise support, there is a through hole at the axis place of this support, settle in this through hole one can be enclosed within shape on the machine shaft such as the cup scholar of abacus bead shape, this glass scholar outside is wrapped in a cotton circle of oil, comprise that also one is pressed in gland in the rack ventilating hole with the cup scholar, the inwall of described through hole is divided into successively the diameter that is connected by little and large first, second, the 3rd step, wherein the sidewall of first step surrounds one coniformly, is used for the described cup of support scholar; It is one cylindric that the sidewall of second step surrounds, and is used for laying the cotton circle of described oil; It is one cylindric that the sidewall of the 3rd step surrounds, and is used for the described gland of clamping; Described cup scholar is glanded and is pressed on the first step.

Above-mentioned support extends respectively two cantilevers to both sides, the end of cantilever connects a fixed leg, and the center of fixed leg has a screw hole, and the axis of screw hole is parallel with machine shaft.

Compared with prior art, the utility model contact-making surface is little, and frictional resistance is little, easy to lubricate, wearing and tearing are little, aligning speed is fast, has wide market prospects.

Description of drawings

Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:

Fig. 1 is the side sectional view of the utility model preferred embodiment;

Fig. 2 is the partial enlarged view of Fig. 1;

Fig. 3 is the three-dimensional view of the utility model preferred embodiment;

Fig. 4 is the assembling effect figure of the utility model on motor.

Embodiment

The utility model has disclosed the aligning support of a kind of fixedly low-power machine rotating shaft, it comprises support 1 referring to Fig. 1, there is a through hole at the axis place of this support, settle in this through hole one can be enclosed within shape on the machine shaft 5 such as the cup scholar 2 of abacus bead shape, this glass scholar outside is wrapped in a cotton circle 4 of oil, and support comprises that also one is pressed in gland 3 in the through hole with the cup scholar.Referring to the enlarged drawing shown in Fig. 2, the inwall of through hole is divided into successively the diameter that is connected by first, second, third little and large step, and wherein the sidewall of first step surrounds one coniformly, is used for the described cup of support scholar; It is one cylindric that the sidewall of second step surrounds, and is used for laying the cotton circle of described oil oil; It is one cylindric that the sidewall of the 3rd step surrounds, and is used for the described gland of clamping; Described gland has elasticity, the cup scholar can be pressed on the first step.Cup scholar's 2 profile is approximate spherical, can rotate around the axle center, also can about rocking by a small margin, when the axle center of the aligning support that is contained in the motor rear and front end does not overlap, because the cup scholar can a deflection low-angle, therefore aligning support can the adjustable axle heart, make the motor even running.The cup scholar is a circular lines with contacting of first step, and frictional force is little, and aligning is relatively fast; Because friction area is little, lubricant effect improves.

In preferred embodiment, oil cotton 4, its inside stores lubricating oil, and has slow releasing function, can long-term greaser scholar.

Referring to Fig. 3, support extends respectively two cantilevers to both sides, and the end of cantilever connects a fixed leg 6, and the center of fixed leg has a screw hole 7, and the axis of screw hole is parallel with machine shaft.

Fig. 4 has showed the assembling effect figure of the utility model on motor, a motor needs former and later two aligning supports, machine shaft passes the cup scholar of former and later two aligning supports, screw hole 7 on the aligning support that screw 10 passes the left side and the aligning support on the installing hole on the stator 9 and the right are installed are spirally connected (screw hole 7 is provided with internal thread), what icon 8 was indicated is the rotor that is fixed on the machine shaft.

Above embodiment is only for illustrating non-providing constraints.Anyly do not break away from the application's spirit and category, and to its equivalent modifications of carrying out or change, all should be contained among the application's the claim scope.
