Abstract

The utility model relates to a stirring shaft comprising a shaft handle (1) and a stirring shaft (2), wherein the shaft handle (1) is connected with a power shaft. The stirring shaft is characterized in that the lower part of the shaft handle (1) is provided with a T-shaped groove (3), the upper part of the stirring shaft (2) corresponding to the T-shaped groove (3) is provided with a T-shaped protrusion (4); and the shaft handle (1) is connected with the stirring shaft (2) through the T-shaped groove (3) and the T-shaped protrusion (4). The shaft handle and the stirring shaft can ensure high coaxiality of the entire shaft; the internal taper of an external sleeve is the same as the taper of the shaft handle and the stirring shaft; as the external sleeve is under a downward gravity, the shaft can automatically adjust the coaxiality of the installed entire shaft along a taper line after rotating; and the combined face of an upper half part and a lower half part of the stirring shaft is basically the longitudinal section of the shaft, so that the torque force in rotating is obtained by the anti-radial shear force of the entire shaft, and the deformation is small, thereby ensuring the service life.

Description

A kind of shaft

Technical field

The utility model relates to a kind of shaft.

Background technology

In industrial production, be unable to do without and stir, the stirring of some industry need be changed the mixing part continually, when for example producing coating,, stirred the coating of one barrel of A color owing to the color difference of coating, rethink the coating that stirs the B color, must change mixing part operation for convenience, raise the efficiency, just need the junction should be simple and convenient, guarantee certain axiality again, tightness.Now Chang Yong connected mode has following several: a kind of to be its footstalk be connected by screw locking with shaft is two-part, and its advantage: processing is simple, shortcoming: operation inconvenience, swing is severe, and screw rod is dangerous when long.Another kind is that its footstalk is connected by alignment pin and location eye with shaft is two-part, and overcoat, its advantage: change easy to operate, shortcoming: torsion that minor axis service time of precision the rotates counter-bending power by alignment pin is arranged, because it is very thick that alignment pin can not be done, along with the lengthening alignment pin of service time and the gap between the eye of location must be strengthened, rotate, the swing meeting of paddle is increasing.

Summary of the invention

The objective of the invention is to avoid the deficiencies in the prior art that a kind of shaft is provided, thereby efficiently solve the problems of the prior art.

For achieving the above object, the technical scheme that the present invention takes is: described a kind of shaft, include the footstalk (1) and the shaft (2) that link to each other with line shaft, its characteristics are: the bottom of described footstalk (1) is provided with T type groove (3), shaft (2) top corresponding with T type groove (3) is provided with T type projection (4), and footstalk (1) links to each other with T type projection (4) by T type groove (3) with shaft (2).

Described footstalk (1) and outside, shaft (2) junction are pyramidal structure, the outside correspondence in footstalk (1) and shaft (2) junction is provided with overcoat (5), and the inner surface of overcoat (5) and footstalk (1) and shaft (2) outside, junction be the identical pyramidal structure of tapering not.Described T type groove (3) is the identical pyramidal structure of tapering with the contact-making surface of T type projection (4).

The beneficial effects of the utility model are: the method that its footstalk and shaft processing obtain is, at first obtain to have in the middle of one the bearing of frustum, by modern manufacturing process, be divided into the as above footstalk and the shaft of diagram shape again. so just can guarantee that bearing has quite high axiality; The internal taper of its overcoat is identical with the tapering of footstalk and shaft, because overcoat is subjected to the effect of downward gravity, after axle rotates, can adjust the axiality that the back bearing is installed automatically along the awl line; The faying face of its first half and Lower Half is the vertical section of axle substantially, and the torsion when rotating like this is the anti-radial shear power acquisition by bearing, and distortion can be very little, is enough to guarantee service life like this.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.

Shown in Fig. 1,2,3,4, include the footstalk 1 and the shaft 2 that link to each other with line shaft, its characteristics are: the bottom of described footstalk 1 is provided with T type groove 3, and shaft 2 tops corresponding with T type groove 3 are provided with T type projection 4, and footstalk 1 links to each other with T type projection 4 by T type groove 3 with shaft 2.

Described footstalk 1 and outside, shaft 2 junctions are pyramidal structure, and the outside correspondence in footstalk 1 and shaft 2 junctions is provided with overcoat 5, and the inner surface of overcoat 5 and footstalk 1 and outside, shaft 2 junction be the identical pyramidal structure of tapering not.Described T type groove 3 is the identical pyramidal structure of tapering with the contact-making surface of T type projection 4.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
