Abstract
The utility model provides a telescopic gear transmission shaft. The telescopic gear transmission shaft comprises a shaft lever and connecting pieces connected to the two sides of the shaft lever, wherein the shaft lever comprises a shaft sleeve and a movable shaft, the shaft sleeve is a cup-shaped hollow cylinder, and the internal surface of the shaft sleeve is of a thread structure; the movable shaft is a cylinder with an external thread; and the movable shaft is screwed into the shaft sleeve or screwed out of the shaft sleeve through the thread so as to shorten or lengthen the shaft lever. The telescopic gear transmission shaft provided by the utility model has the advantages that the transmission shaft can be properly adjusted at a certain shaft length according to job demands and does not need to be matched with new products, the usage cost is reduced, and the operating efficiency is improved.
Description
Technical field
The utility model relates to mechanical transmission fields, is specifically related to a kind of expansion teeth wheel shaft.
Background technique
Gearing shaft refers to the mechanical parts that support rotational parts and turn round therewith to transmit motion, moment of torsion or moment of flexure.Be generally round metal shaft-like, each section can have different diameters.The part of doing rotation motion in machine is just contained on axle.
According to the nemaline difference of axle, axle can be divided into bent axle and d-axis two classes.Carrying situation according to axle, can be divided into again: 1. rotating shaft, during work, not only bear moment of flexure but also bear moment of torsion, and be modal axle in machinery, as axle in various retarders etc.2. axle, is used for supporting that rotational parts only bears moment of flexure and transmitting torque not, and some axle is rotated, and as the axle of railway vehicle etc., some axle is not rotated, as the axle of supporting pulley etc.3. transmission shaft, is mainly used to transmitting torque and does not bear moment of flexure, as the long optical axis in crane movable mechanism, the live axle of automobile etc.
Existing gearing shaft mostly is fixed length, for fixing mechanical transmission, but sometimes due to need of work, need to adjust certain shaft length, needs other purchase, and for little operation, cost is relatively high, buys inconvenient.
Model utility content
For the problems referred to above, the utility model provides a kind of expansion teeth wheel shaft, can without again mating new product, reduce user cost according to the certain shaft length of the suitable adjustment of need of work, increases work efficiency.
The technical solution of the utility model is: a kind of expansion teeth wheel shaft, comprise axostylus axostyle and the link that is connected to axostylus axostyle both sides, and described axostylus axostyle comprises sleeve and moving axis; Described sleeve is the cylindrical body of cup-shaped hollow, and internal surface is worm structure; Described moving axis is with externally threaded cylindrical body; And described moving axis is passed in and out described sleeve, is shortened and elongate described axostylus axostyle by screw thread rotation.
Further, described sleeve and moving axis joint are socketed with lasso, and described sleeve is connected a side external surface with moving axis be worm structure; Described lasso comprises the macropore fillet of screw and the aperture fillet of screw, the supporting rotation socket of the described macropore fillet of screw and described sleeve outside thread, the supporting rotation socket of the described aperture fillet of screw and described moving axis outside thread.
Further, described sleeve outside thread place is processed with several keyways, and described lasso and keyway corresponding part are processed with via hole; Retainingf key is fixedly connected with keyway by via hole.
Further, described keyway number is 4.
The beneficial effects of the utility model are: a kind of expansion teeth wheel shaft is provided, can without again mating new product, reduces user cost according to the certain shaft length of the suitable adjustment of need of work, increase work efficiency.Meanwhile, use lasso and retainingf key fixedly sleeve and lasso, device integral installation is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of expansion teeth wheel shaft;
Fig. 2 is the sectional view of expansion teeth wheel shaft sleeve and moving axis joint.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of expansion teeth wheel shaft, comprises axostylus axostyle and the link 5,6 that is connected to axostylus axostyle both sides, and described axostylus axostyle comprises sleeve 1 and moving axis 2; Described sleeve 1 is the cylindrical body of cup-shaped hollow, and internal surface is worm structure; Described moving axis 2 is with externally threaded cylindrical body; And described moving axis 2 is passed in and out described sleeve 1, is shortened and elongate described axostylus axostyle by screw thread rotation.
Further, described sleeve 1 is socketed with lasso 3 with moving axis 2 joints, and described sleeve 1 is connected a side external surface with moving axis 2 be worm structure; Described lasso 3 comprises the macropore fillet of screw and the aperture fillet of screw, the described macropore fillet of screw and the supporting rotation socket of described sleeve 1 outside thread, the described aperture fillet of screw and the supporting rotation socket of described moving axis 2 outside thread.
Further, described sleeve 1 outside thread place is processed with 4 keyways, and described lasso 3 is processed with via hole with keyway corresponding part; Retainingf key 4 is fixedly connected with 3 by via hole with keyway.
In the time need to changing the length of gearing shaft, first remove retainingf key 4, rotate lasso 3, lasso 3 and sleeve 1 are departed from, rotate again moving axis 2 and adjust gearing shaft to Len req, then rotate lasso 3, make it to be fixedly connected with sleeve 1, then retainingf key 4 is installed, and gearing shaft reaches Len req.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, within not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
