Embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 1 to 5; The motor output shaft assembly structure improves, and comprises casing 1, end cap 2, output shaft 3 and bearing 4, and output shaft is installed in the casing and stretches out end cap; Bearing holder (housing, cover) is located on the output shaft and cooperates with installing hole 21 in the end cap; Be provided with the screens structure that prevents that end cap from rotating between said end cap and the casing, in casing, be provided with the location structure of axial location bearing, said end cap and location structure are affixed.In the present embodiment, said screens structure comprises the axial notch 11 that is located at the casing end and is located at the axial 22 on the end cap, axial and axial notch corresponding matching; Said location structure comprises the spacer 5 and circlip 6 that is set on the output shaft; Spacer is positioned at the inboard of bearing; Circlip is positioned at the outside of bearing, and casing is provided with the caulking groove 12 with the spacer axial location, and caulking groove comprises the peristome 121 that extends internally from the casing end and radially is located at the radial part 122 that is communicated with peristome on the casing; The two ends of spacer are provided with in the radial part that positioning end 51 is stuck in caulking groove, and said end cap is affixed through threaded fastener and spacer.
In the foregoing description, said axial notch overlaps with the peristome of caulking groove, and said axial cooperates with the peristome of caulking groove; Axial notch is communicated with the radial part of caulking groove; Reduce the quantity that is provided with of groove or caulking groove like this, reduce the processing technology step, make that also case strength is guaranteed.Said threaded fastener is a screw, and the positioning end of said spacer is provided with the screwed hole 52 with the screw corresponding matching.In addition, the peristome of said caulking groove also can be convenient to spacer and be slipped into card well along the curve setting along the straight line setting.
The installation process of the utility model is following: earlier spacer, bearing and circlip are installed on the output shaft; With pack into casing and make the positioning end of spacer corresponding with the peristome of caulking groove of output shaft, output shaft is advanced in casing, the positioning end that makes spacer inwardly slides into along the peristome of caulking groove again; Rotary output axis slips in the radial part of caulking groove the positioning end of spacer and obtains axial location then; Then that axial on the end cap and the axial notch corresponding matching on the casing is good, cooperate with screwed hole on the spacer and tighten the axial restraint that screw is realized end cap thereby again screw is passed end cap, and because the restriction of screw makes spacer to rotate; Therefore spacer fixes; Bearing shaft is to having good positioning, and the whole erection process is very convenient quick, also can be very convenient and change maintenance.Narration is the situation that the opening portion of axial notch and caulking groove is arranged above; And overlap situation about being provided with the peristome of caulking groove for axial notch; Just make the peristome corresponding matching of axial and caulking groove, screw-driving is got final product again, the positioning end of spacer can come limit rotation through axial again like this; The structure that is arranged of the opening portion of groove and caulking groove is more reliable and more stable to axial, so the utility model preferably overlaps setting with axial notch with the peristome of caulking groove.
