Abstract
Disclosed in the utility model is an apparatus for bearing limiting and brush holder fixing. A motor comprises a casing (1), an end cover (2) and a motor shaft (3); a brush holder (4) is installed inside the casing (1); the end cover (2) has a recessed portion; a bearing (5) is arranged in the recessed portion; and the motor shaft (3) passes through the central holes of the brush holder (4) and the bearing (5). Besides, a bearing fixed plate (6) is also includes; one side of the bearing fixed plate (6) is tightly compressed at the brush holder (4) and the other side thereof is tightly compressed at the bearing (5). According to the apparatus provided by the utility model, the brush holder and the bearing fixed plate are cooperated with notches of the motor casing; the bearing fixed plate and the brush holder are fastened axially by fastening bolts; and the bearing is fixed axially by the bearing fixed plate. Therefore, the provided apparatus has advantages of simple structure as well as convenient replacement of the bearing ant the brush holder.
Description
Technical field
The utility model belongs to machine field, specifically spacing the and brush holder fixture of a kind of bearing.
Background technology
The effect of brush holder is by spring pressure to be added on the carbon brush that contacts with commutator or collector ring surface sliding, makes its conduction current stably between fixed body and rotary body.Concerning motor, brush holder and carbon brush all are very important parts.No matter the characteristic of carbon brush how well, when brush holder was improper, carbon brush not only can not be given full play to its good characteristic, and brought very large impact can for performance and the life-span of motor itself.
The brush holder of existing motor and bearing are fixing respectively, and such electric machine structure more complicated is relatively more difficult when changing brush holder and bearing.
The utility model content
In order to solve the above-mentioned technical problem that exists in the prior art, the utility model provides a kind of bearing of motor spacing and brush holder fixture, described motor comprises casing, end cap and motor shaft, brush holder is equipped with in described casing inside, and described end cap has recess, and bearing is set in the recess, described motor shaft passes the centre bore of brush holder and bearing, comprise bearing (setting) plate, the described brush holder of described bearing (setting) plate one side compression, opposite side compresses described bearing.
Further, the opposite end of described casing is provided with notch, and described brush holder has two the first ears, described the first ear has the first hole, described bearing (setting) plate has two the second ears, and described the second ear has the second hole, and described the first and second ears embed in the described notch.
Further, described first, second hole of trip bolt insertion is fixed on described brush holder and bearing (setting) plate on the described casing.
Spacing and the brush holder fixture of bearing of the present utility model is by cooperating brush holder and bearing (setting) plate with the motor case notch, by trip bolt bearing (setting) plate and brush holder are axially tightened up, simultaneously by bearing (setting) plate with the bearing axial restraint, it is simple in structure, makes things convenient for the replacing of bearing and brush holder.
