Abstract
The utility model provides a protecting jacket on the head of a traction motor shaft, and relates to a traction motor, in particular to a protecting jacket on the head of a traction shaft. The protecting jacket mainly solves the problem that the existing protecting jacket adopted on the head of the motor shaft is cylindrical or tapered, wherein the cylindrical protecting jacket is easy to fall off, and the tapered protecting jacket can not prevent the R28 arc surface and the R6 arc surface on the motor shaft from being accidentally collided. The shape of the protecting jacket on the head of the traction motor shaft is the same as the taper of the shape of the head of the motor shaft, and one end of the protecting jacket with larger diameter is longer than the head of the motor shaft. As the protecting jacket can be preferably fit with the head of the motor shaft, the protecting jacket is hard to fall off and is convenient to sleeve and take; as the end of the protecting jacket with larger diameter is longer than the head of the motor shaft, the protecting jacket increases the effective protection to the R28 arc surface and the R6 arc surface on the motor shaft; and as being made from rubber, the protecting jacket effectively prevents the head of the motor shaft from being accidentally and electrically burnt caused by the electric work, and relieves the impact on each machinery.
Description
Technical field
The utility model relates to a kind of traction electric machine, relates to the protective sleeve on the traction electric machine spindle nose specifically.
Background technology
Traction electric machine is the vitals of diesel locomotive and electric locomotive portion out of shape, the traction electric machine rotating shaft is being overhauled, is being processed, lifts, transports, assembles, piling up in the process, its spindle nose position is owing to expose, very easily accidental injury, in case damage may jeopardize traffic safety, can not repair welding after the damage, change axle and then can cause than large economy again and lose, and at present the safeguard measure that motor shaft head adopted being had the cylindrical rubber protective jacket, shortcoming is easily to come off; The employing papery sheath that has, its shortcoming is disposablely to use, and operation inconvenience, protection effect is poor; Also have the band of employing tapering elastometric boot, effect is better, but can not carry out the protection that accident is collided with to the arc surface of R28, R6 on the motor shaft.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of traction electric machine spindle nose protective sleeve that makes R28 on traction electric machine spindle nose and the motor shaft, R6 arc surface all can obtain protecting that proposes.
Technical solution of the present utility model is: the shape of traction electric machine spindle nose protective sleeve is identical with the profile taper of motor shaft head, and the end that the protective sleeve diameter is big grows motor shaft head.
Protective sleeve described in the technical solution of the present utility model grows the part of motor shaft head and just R28 arc surface on the motor shaft and R6 arc surface is kept off in protective sleeve.
Protective sleeve described in the technical solution of the present utility model adopts elastomeric material to make.
The utility model is because identical with the profile of motor shaft head, be that tapering is identical, therefore both can well coincide after protective sleeve being inserted in motor shaft head, difficult drop-off, and suit, win very convenient, the end that the protective sleeve diameter is big grows motor shaft head, has increased the effective protection to the arc surface of R28, R6 on the motor shaft; The utility model adopts elastomeric material, has avoided the unexpected electric burn that motor shaft head caused because of electric operation and the impact that has effectively slowed down all kinds of machineries effectively.
Description of drawings
Fig. 1 is that the utility model is sleeved on the structural representation on the motor shaft head.
Embodiment
As shown in Figure 1, protective sleeve 3 is identical with the profile of motor shaft head 6, be that protective sleeve 3 is identical with the tapering of motor shaft head 6, as 1: 10, measure-alike, size by motor shaft head 6 is decided, and protective sleeve 3 adopts elastomeric materials to make, so protective sleeve 3 very convenient and difficult drop-off when being sleeved on the motor shaft head 6; The end that protective sleeve 3 diameters are big grows motor shaft head 6; be the axial length of the axial length of protective sleeve 3 greater than motor shaft head 6; it is outside circular-arc that this port of protective sleeve 3 is; the part that protective sleeve 3 grows is just blocked R28 arc surface 1 on the motor shaft and R6 arc surface 2 in protective sleeve 3, and the oil groove 4 on the motor shaft head 6, the conical surface 5 is also effectively protected simultaneously.
Claims (3)
1. traction electric machine spindle nose protective sleeve, it is characterized in that: the shape of protective sleeve (3) is identical with the profile taper of motor shaft head (6), and the end that protective sleeve (3) diameter is big grows motor shaft head (6).
2. traction electric machine spindle nose protective sleeve according to claim 1, it is characterized in that part that described protective sleeve (3) grows motor shaft head (6) just with the R28 arc surface (1) on the motor shaft and R6 arc surface (2) retaining in protective sleeve (3).
3. traction electric machine spindle nose protective sleeve according to claim 1 is characterized in that described protective sleeve (3) adopts elastomeric material to make.
