Abstract
The utility model relates to a shaft sleeve which comprises a shaft sleeve body. A spiral-shaped cooling groove is arranged inside the shaft sleeve body, the spiral-shaped cooling groove is provided with cooling liquid, and two ends of the spiral-shaped groove are provided with round grooves and are communicated with the outside through the round grooves. Plugs are arranged inside the round grooves. When a large amount of heat is generated due to the friction between the shaft sleeve and a shaft, the cooling liquid inside the spiral-shaped cooling groove can absorb the heat generated during the friction process timely, the temperature of the shaft sleeve is lowered, so that the shaft sleeve can not be damaged by high temperature, the service life of the shaft sleeve is prolonged, the maintenance cycle of mechanical equipment is prolonged, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of axle sleeve, particularly a kind of axle sleeve that can in time absorb the heat that produces in the friction process.
Background technique
In machinery, cause the wearing and tearing of part because of the long-term rotation meeting of axle, therefore just necessary renewal part uses axle sleeve just can reduce the wearing and tearing of axle and part when the gap of axle and hole in piece part may wear to a certain degree.Axle sleeve also plays centralized positioning and the bearing of stationary axle, does not shake and the effect of generation displacement when not allowing it because of running.Because the High Rotation Speed of axle, axle sleeve can with producing a large amount of heats because of friction between the axle, if these heats can not in time leave, can affect the working life of bearing.In order to absorb the heat that produces in these friction processes; can adopt water-cooled mode; in the axle sleeve body, have a circle cooling bath; cooling liquid is housed, when longer such as the length of axle sleeve, owing to only having a circle cooling bath in the axle sleeve body in cooling bath; the absorption heat is untimely; or can affect the working life of bearing, increase the frequency of machinery shutdown maintenance, reduce manufacturing efficiency.
The model utility content
The utility model purpose is that a kind of axle sleeve that can in time absorb the heat that produces in the friction process is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of axle sleeve, comprise the axle sleeve body, and have the spirality cooling bath in the described axle sleeve body; In the described spirality cooling bath cooling liquid is housed.
Preferably, the two ends of described spirality cooling bath are provided with circular groove, and communicate with the external world by circular groove; Be provided with stopper in the described circular groove.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Axle sleeve of the present utility model, owing to having the spirality cooling bath in the axle sleeve body, cooling liquid is housed in the cooling bath, between axle sleeve and axle because friction and after producing a large amount of heats, the cooling liquid in the spirality cooling bath can in time absorb the heat that produces in the friction process has reduced the temperature of axle sleeve, so that axle sleeve can not damage because of higher temperature, increase the working life of axle sleeve, increased the machinery maintenance cycle, improved manufacturing efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of axle sleeve of the present utility model;
Accompanying drawing 2 is the structural representation of axle sleeve of the present utility model;
Wherein: 1, axle sleeve body; 2, spirality cooling bath; 3, cooling liquid; 4, circular groove; 5, stopper.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of axle sleeve shown in accompanying drawing 1,2 comprises axle sleeve body 1, has spirality cooling bath 2 in this 1 body of described axle sleeve; In the described spirality cooling bath 2 cooling liquid 3 is housed; The two ends of described spirality cooling bath 3 are provided with circular groove 4, and communicate with the external world by circular groove 4; Be provided with stopper 5 in the described circular groove 4.Between axle sleeve body 1 and axle because the friction and after producing a large amount of heats, cooling liquid 3 in the spirality cooling bath 2 can in time absorb the heat that produces in the friction process, reduced the temperature of axle sleeve body 1, so that axle sleeve body 1 can not damage because of higher temperature, increased the working life of axle sleeve, increase the machinery maintenance cycle, improved manufacturing efficiency.When carrying out the safeguarding of machinery, can corkage 5, change the cooling liquid 3 of spirality cooling bath 2, so that cooling liquid 3 can better absorb the heat that produces in the friction process.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
