Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of draw bail of shaft, comprise the first axle 10, second axle 20, positioning sleeve 30, the end face of the first axle 10 first end is skewed, the end face of the first axle 10 first end is provided with at least one first recess 102, at least one first protuberance 104, the end face of described second axle 20 second end is skewed in what mate with the end face of the first axle 10 first end, the end face of the second axle 20 second end is provided with at least one second protuberance 202 mated with the first recess 102, at least one the second recess 204 mated with the first protuberance 104, the first end of the first axle 10 and the second end of the second axle 20 to be coordinated with the first protuberance 104 by the first recess 102 and the second recess 204 and the second protuberance 202 are connected, on the outer wall that described positioning sleeve 30 is set in the first axle 10 first end simultaneously and on the outer wall of the second axle 20 second end.
To be coordinated with the first protuberance 104 by the first recess 102 and the second recess 204 coordinates with the second protuberance 202 and makes the first axle 10 and the second axle 20 mutually hook stressed joint, positioning sleeve 30 is set on the outer wall of the first axle 10 first end and the second axle 20 second end simultaneously, the first axle 10 and the second axle 20 is avoided to get loose, because the first recess 102 and the first protuberance 104 are arranged on the end face in the first skewed axle 10 first end, second recess 204 and the second protuberance 202 are arranged on the end face in the second skewed axle 20 second end, during rotation, first recess 102 and the first protuberance 104, second recess 204 and the second protuberance 202 are strained mutually, obtain axial and radial active force simultaneously, this connecting mode rotating accuracy is higher, run more steady, and install, easy to maintenance, fast, be particularly useful for relatively large vertical storage tank agitator, the storage tank of preferred 2000L to 20000L.
As shown in Figure 1, the end face of the first axle 10 first end described in the present embodiment is the first surface tilting to extend to its axial direction, this first surface is provided with described first protuberance 104 of described first recess 102, this first recess 102 and the smooth connection of the first protuberance 104, the end face of described second axle 20 second end is the second curved surface mated with first surface, this second curved surface is provided with described second protuberance 202 of described second recess 204, this second recess 204 and the smooth connection of the second protuberance 202.Described positioning sleeve 30 is fixedly connected with the first axle 10, second axle 20 respectively by screw or rivet.The shape of first surface and the second curved surface does not limit, according to the actual requirements, first surface also can be arranged multiple described first recess 102 and/or multiple described first protuberance 104, second curved surface is arranged multiple described second recess 204 and/or multiple described second protuberance 202, but need mutually hook tightly between the two, described positioning sleeve 30 and the first axle 10, with tighter matched in clearance between second axle 20, both convenient installation, axiality can be guaranteed again, simultaneously positioning sleeve 30 by screw or rivet respectively with the first axle 10, second axle 20 is fixedly connected with, when preventing the first axle 10 and the second axle 20 from rotating, positioning sleeve 30 slides, the first axle 10 and the second axle 20 is caused to depart from.Described first surface and the second curved surface, by the machine-shaping of Linear cut mode, ensure the fitness of two cut surfaces.
With reference to Fig. 2, a kind of agitator, comprise the draw bail of above-mentioned shaft, reducing motor, at least one paddle 1, first axle 10 the second end be connected with described reducing motor, described paddle 1 is sleeved on the second axle 20, and its second end close.Wherein the first axle 10 is minor axis, second axle 20 is major axis, reducing motor runs, the first axle 10 is driven to rotate, because the first axle 10 and the second axle 20 are strained mutually by the first recess 102 and the first protuberance 104, second recess 204 and the second protuberance 202, to be locked its junction by locating shaft, so the second axle 20 rotates thereupon simultaneously, drive paddle 1 to rotate, realize stirring.Agitator described in the present embodiment, comprises two paddles, 1, two paddle 1 compartment of terrains and is enclosed within the second axle 20.Such setting make stirring evenly.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
