Detailed description of the invention
In order to make technical matters to be solved of the present utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment: a kind of synchronous dynamo output shaft protecting sleeve as depicted in figs. 1 and 2; this protecting sleeve is enclosed within synchronous dynamo output shaft; in order to protect output shaft 4; wherein synchronous dynamo output shaft 4 is generally provided with one or two key arranged along output shaft length direction, and therefore protecting sleeve also will be inserted in this key.
In order to produce with easy for installation, this protecting sleeve is made up of the first half portion, the second half portion and multiple elastic fastener.First half portion, the second half portion couple together by multiple elastic fastener, form a cover completed.Above-mentioned first half portion comprises the first adapter plate 1a and the first half body 2a; Second half portion comprises the second adapter plate 1b and the second half body 2b.Wherein the first half body 2a are all identical with the second half body 2b size and shapes, position centered by axis, Central Symmetry.Also namely as follows: the first half body 2a and the second half body 2b are all in semi-cylindrical shaped, and the first adapter plate 1a and the second adapter plate 1b is separately fixed at its inner; As illustrated in fig. 1 and 2, the first half body 2a upsides are provided with the first baffle plate 22 that cross section is inverted L-shaped, and corresponding lower side is provided with second baffle 23.In contrast, the second half body 2b are provided with the first baffle plate 22 that cross section is inverted L-shaped in its lower side, upside is provided with second baffle 23.So, on whole protecting sleeve top, the first baffle plate 22 in inverted L-shaped on the first half body 2a is corresponding with second baffle 23 position on the second half body 2b; In whole protecting sleeve bottom, the first baffle plate 22 in inverted L-shaped on the second half body 2b is corresponding with second baffle 23 position on the first half body 2a.Above-mentioned first baffle plate 22 top is equipped with adapter plate 220, adapter plate and the first baffle plate 22 outward flange free end docking be connected as a single entity, and with the first baffle plate 22 plan vertical.Adapter plate 220 is provided with multiple through hole 220a along its length, and second baffle 23 laterally corresponding is with it provided with multiple screw 23a.Above-mentioned elastic fastener comprises bolt 3 and spring 31, and bolt 3 comprises head and screw rod, and spring 2 is enclosed within screw rod.Screw rod on bolt 3 is horizontally through the through hole 220a on adapter plate 220, is then threaded on the screw 23a of described second baffle 23.Spring 31 is enclosed within screw rod and position and is between bolt head and adapter plate 220, and the first baffle plate 22 of two side ends is connected with second baffle 23 elasticity and forms the key protection groove for the protection of key on output shaft by multiple elastic fastener respectively.When tightening screw rod; spring 31 impels the first baffle plate 22 and second baffle 23 to clamp strength increasing; clamp key; like this can locate well makes the sleeve body portion of synchronous dynamo output shaft protecting sleeve surround output shaft 4; can leave gap between output shaft 4 and protecting sleeve, and when colliding all under the action of the spring, the little formation that can shift flexibly of synchronous dynamo output shaft protecting sleeve so cushions the strength of colliding with; maximum protection output shaft is neither collided with and is not worn, and protected effect is good.
First adapter plate 1a of the present utility model and the second adapter plate 1b is used to whole protecting sleeve to be fixed on synchronous dynamo casing; some synchronous dynamo casing has reserved screw; this situation; first adapter plate 1a and the second adapter plate 1b is equipped with mounting hole, is fixed by mounting hole and reserved screw.In addition, adhered layer can also be established on the first adapter plate 1a and the second adapter plate 1b inside face, be fixed by bonding, prevent protecting sleeve from axially outwards skidding off output shaft.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
