Abstract
The utility model discloses a but elasticity screw-nut is vice, including the lead screw, the lead screw in proper order with main nut and vice nut threaded connection, the vice nut outside is provided with the one end of tight regulation piece, the tight regulation piece other end through the elastic component with the main nut orientation one side butt of vice nut. The utility model adopts the above structure can elasticity screw-nut pair, through twisting move adjusting nut corotation or reversal, extrude the elastic rubber circle for form a thrust between the main and auxiliary nut, and then eliminate the clearance between main nut and the lead screw, thereby reach the purpose that reduces transmission clearance, adjustment transmission frictional force.
Description
Technical Field
The utility model relates to a transmission technology especially relates to a but elasticity screw-nut is vice.
Background
Often perpendicular transmission shaft receives gravity to influence and need to take the auto-lock, and T type nut is vice to have better auto-lock performance, so can choose T type screw rod nut pair for use on general manual instrument equipment to carry out the transmission, T type screw rod nut is vice to include lead screw and main nut, because the nut does not receive transverse thrust, consequently there is the fit clearance between nut and the lead screw, and because be sliding friction between lead screw and the nut in the use, lead screw or nut produce wearing and tearing easily, also can produce very big clearance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a but elasticity screw-nut is vice, moves adjusting nut corotation or reversal through twisting, extrudees the elastic rubber circle for form a thrust between the major-minor nut, and then eliminate the clearance between major-nut and the lead screw, thereby reach the purpose that reduces transmission clearance, adjustment transmission frictional force.
In order to achieve the purpose, the utility model provides a but elasticity screw-nut is vice, including the lead screw, the lead screw in proper order with main nut and vice nut threaded connection, the vice nut outside is provided with the one end of tight regulation piece, the tight regulation piece other end through the elastic component with the main nut orientation one side butt of vice nut.
Preferably, the tightness adjusting piece is an adjusting nut, and the inner side of the adjusting nut is in threaded connection with the outer side of the auxiliary nut.
Preferably, the main nut is a T-shaped nut.
Preferably, the elastic element is an elastic rubber ring fixed on the main nut.
Therefore, the utility model adopts the above structure can elasticity screw-nut pair, through twisting adjusting nut corotation or reversal, extrudees the elastic rubber circle for form a thrust between the major-minor nut, and then eliminate the clearance between major-nut and the lead screw, thereby reach the purpose that reduces transmission clearance, adjustment transmission frictional force.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural view of a screw nut pair capable of being tightened or loosened according to an embodiment of the present invention.
Wherein: 1. a screw rod; 2. a main nut; 3. an elastic member; 4. a slack adjuster; 5. and a secondary nut.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
Fig. 1 is the embodiment of the utility model provides a vice structural schematic diagram of elasticity screw-nut, as shown in fig. 1, the utility model discloses a structure, including lead screw 1, lead screw 1 in proper order with main nut 2 and vice nut 5 threaded connection, the 5 outsides of vice nut are provided with the one end of tight regulation piece 4, the tight regulation piece 4 other end through elastic component 3 and main nut 2 towards one side butt of vice nut 5. Wherein, the tightness adjusting piece 4 is an adjusting nut, and the inner side of the adjusting nut is in threaded connection with the outer side of the auxiliary nut 5. The main nut 2 is a T-shaped nut. The elastic member 3 is an elastic rubber ring fixed to the main nut 2.
The working principle is as follows:
when the screw rod 1 or the nut has a gap due to friction, the adjusting nut is screwed to rotate forwards or reversely, so that the adjusting nut moves towards the main nut 2 to extrude the elastic rubber ring, a reverse thrust is formed between the main nut and the auxiliary nut through the adjusting nut, the balance between the friction force and the pretightening force is achieved at the moment, the main nut 2 and the screw rod 1 are tightened up under the action of the reverse thrust, the gap is eliminated, the gap of the screw rod 1 in the transmission process can be kept, and the purposes of reducing the transmission gap and adjusting the transmission friction force are achieved.
Therefore, the utility model adopts the above structure can elasticity screw-nut pair, through twisting adjusting nut corotation or reversal, extrudees the elastic rubber circle for form a thrust between the major-minor nut, and then eliminate the clearance between major-nut and the lead screw, thereby reach the purpose that reduces transmission clearance, adjustment transmission frictional force.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
