Abstract
The utility model relates to the technical field of motor fittings, especially to a high-efficiency motor end cover comprising a cover body, a shaft cylinder, and installing holes. The shaft cylinder is arranged at the center of the cover body; the installing holes are arranged around the cover body; and a bearing sleeve and a clamp ring are arranged in the shaft cylinder. Because the bearing sleeve is arranged inside the shaft cylinder of the cover body and the elastic metal clamp ring is embedded in the bearing sleeve, when the cover body and a casing of a motor are laminated together by a bolt, a shaft head of the motor is clamped tightly by an inner buckling plate of the clamp ring. The bearing sleeve provides the stable support for the shaft head, thereby maintaining coaxiality of rotation and avoiding shaking; the friction resistance force is small; the structure is stable; and shaking and deviation of the shaft head can be effectively prevented. Therefore, the normal running of the motor is guaranteed.
Description
Technical field
The utility model relates to motor accessory technical field, especially a kind of high efficiency motor end cap.
Background technology
Motor is the general name of conversion equipment between mechanical energy and electric energy, and the principle of most motor application is electromagnetic induction principle.In order to protect motor, usually an end cap need to be installed on motor in reality, this end cap can prevent that external force from causing damage to motor, also can prevent dust, protection against the tide.Existing end cap is single plate body simple in structure, and in the machine operation engineering, the spindle nose front end of motor lacks to be supported, easily shake, and axiality is low, and deviation easily occurs, and affects the normal operation of motor.
The utility model content
Easily cause the motor shaft head shake in order to overcome existing electric motor end cap, the deficiency that the rotating coaxial degree is low, the utility model provides a kind of high efficiency motor end cap.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high efficiency motor end cap, comprise lid, beam barrel and installing hole, and beam barrel is positioned at the central authorities of lid, and mounting hole site is provided with bearing holder (housing, cover) and snap ring in the surrounding of lid in beam barrel.
According to another embodiment of the present utility model, comprise that further the outer ring of bearing holder (housing, cover) is embedded in beam barrel.
According to another embodiment of the present utility model, comprise that further snap ring is embedded in the inner ring of bearing holder (housing, cover).
According to another embodiment of the present utility model, comprise that further the snap ring front end is provided with buckle in elasticity.
The beneficial effects of the utility model are in the beam barrel of lid, bearing holder (housing, cover) to be set, and to inlay the elastic metallic snap ring in bearing holder (housing, cover), in the time of the casing pressing of lid by bolt and motor, the spindle nose of motor penetrates in bearing holder (housing, cover), and is clamped by the interior buckle of snap ring, and bearing holder (housing, cover) provides firm support for spindle nose, the axiality that keeps rotation, avoid rocking, frictional resistance is little, stabilized structure, effectively prevent shake and the deviation of spindle nose, ensured the normal operation of motor.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. lids in figure, 2. beam barrel, 3. installing hole, 4. bearing holder (housing, cover), 5. snap ring, 6. interior buckle.
Embodiment
Be structural representation of the present utility model as Fig. 1, a kind of high efficiency motor end cap comprises lid 1, beam barrel 2 and installing hole 3, and beam barrel 2 is positioned at the central authorities of lid 1, and installing hole 3 is positioned at the surrounding of lid 1, is provided with bearing holder (housing, cover) 4 and snap ring 5 in beam barrel 2.The outer ring of bearing holder (housing, cover) 4 is embedded in beam barrel 2.Snap ring 5 is embedded in the inner ring of bearing holder (housing, cover) 4.Snap ring 5 front ends are provided with buckle 6 in elasticity.
At the interior bearing holder (housing, cover) 4 that arranges of the beam barrel 2 of lid 1, and inlay elastic metallic snap ring 5 in bearing holder (housing, cover) 4, in the time of the casing pressing of lid 1 by bolt and motor, the spindle nose of motor penetrates in bearing holder (housing, cover) 4, and clamped by the interior buckle 6 of snap ring 5, bearing holder (housing, cover) 4 provides firm support for spindle nose, keeps the axiality of rotation, avoids rocking, frictional resistance is little, stabilized structure has effectively prevented from shake and the deviation of spindle nose from having ensured the normal operation of motor.
