Abstract
The utility model discloses a combined sleeve. A plurality of positioning protrusions are arranged on the inner surface of the sleeve and correspond to positioning grooves on a shaft, an annular protrusion is arranged at the front end of the sleeve, and an annular groove corresponding to the annular protrusion is arranged at the rear end of the sleeve. The combined sleeve is suitable for multiple speed reducers, especially suitable for high-speed shafts on the speed reducers, adjustable in length according to needs and capable of guaranteeing stable running of the speed reducers.
Description
Technical field
The utility model relates to a kind of mechanical attachment, specifically designs a kind of modular sleeve.
Background technique
Axle in the retarder often adopts stepped shaft, is convenient to each part is installed on the axle.Because axle and part are being produced some errors of existence, the part of identical producer is adopted in the retarder production that has, and therefore often needs to realize close-coupled by sleeve in the process of assembling.Sleeve generally is located between bearing and the gear.Be loose fit between sleeve and the axle, be not suitable for generally speaking being used in high speed shaft, increased cost of production and expended.
The model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provide a kind of be beneficial to be installed on the high speed shaft and capable of regulating length modular sleeve.
Technological scheme: in order to realize the foregoing invention purpose, a kind of modular sleeve internal surface of the present utility model is provided with some convexes, and described convex is corresponding with the locating slot on the axle; Described barrel forward end is provided with annular projection, and described sleeve rear end is provided with the circular groove corresponding with annular projection.
The utility model can be realized the stacked of this device by the design of circular groove and annular projection, can increase according to demand or reduce the quantity of this sleeve, thus total length of regulating sleeve.
As preferred version of the present utility model, the corresponding sleeve axis of described convex has 3.By with axle on groove engagement, realize that sleeve can along with axle rotates, not affect overall performance.
Install for convenient, described convex and annular projection front end are provided with 45 ° of chamferings.
Beneficial effect: a kind of modular sleeve of the present utility model is simple and practical, is applicable to multiple retarder, is specially adapted to the high speed shaft on the retarder, can regulate as required length, and guarantees the stable operation of retarder.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
In conjunction with Fig. 1, shown in Figure 2, this sleeve 1 internal surface is provided with 3 convexes 2, and convex 2 is corresponding with the locating slot on the axle; Sleeve 1 front end is provided with annular projection 3, and sleeve 1 rear end is provided with the circular groove 4 corresponding with annular projection 3.The utility model can be realized the stacked of this device by the design of circular groove and annular projection, can increase according to demand or reduce the quantity of this sleeve, thus total length of regulating sleeve.By with axle on groove engagement, realize that sleeve can along with axle rotates, not affect overall performance.Install for convenient, convex 2 and annular projection 3 front ends are provided with 45 ° of chamferings.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
