[background technique]

Known, what traditional transmission shaft adopted is round transmission shaft, i.e. the pole structure of real core, and in recent years, in order to adapt to the needs in the practical application, developing again on the basis of traditional transmission shaft the square transmission shaft, i.e. the square rod structure of real core; In actual applications, the effect that transmission shaft plays is that the respective action power that will impose on the one end passes to the respective objects that is connected with its other end, thereby the action that corresponding object is correlated with, but, development along with mechanical transmissioning technology, people are also more and more higher to the requirement of transmission shaft, wherein, the active force how in the transmission shaft transferring power its axle body rotation to be produced is used, namely utilizing the rotating force of its axle body to drive other objects in the transmission shaft transferring power moves accordingly, thereby make the active force that is applied to transmission shaft more fully effectively be carried out utilization, this has become one of important research and development problem of current mechanical transmission fields; At present, in order to solve an above-mentioned difficult problem, make mechanical drive shaft can further expand in actual use its application area, associated production manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but is still developed moulding there are no applicable design so far.

[summary of the invention]

In order to overcome the deficiency in the background technique, the utility model provides a kind of drive shaft sleeve, the rotating force that described sleeve can produce the transmission shaft axle body in square transmission shaft transfer function power effectively utilizes, thereby has reached the purpose of utilizing transmission shaft to drive other respective objects actions in transmission shaft transfer function power.

For achieving the above object, the utility model adopts following technological scheme:

A kind of drive shaft sleeve, described sleeve comprises sleeve pipe, leading screw and feed screw nut; Described sleeve pipe has three at least, and per two adjacent sleeve pipes all are fixed together by a leading screw, and the casing axis line after the connection and the shaft axis of leading screw are overlapping; Described leading screw is tubulose, and the outer wall silk of leading screw is connected to a feed screw nut, and simultaneously, the external diameter of leading screw is identical corresponding with the external diameter of sleeve pipe, and the pore of leading screw is made as internal diameter less than the polygonal holes of casing inner diameter, and the polygonal holes of all leading screws all coincide corresponding.

Described drive shaft sleeve, described sleeve pipe are provided with three of unexpected misfortunes, and long sleeve pipe two ends are fixed together by the sleeve pipe of a leading screw and other two weak points respectively.

Described drive shaft sleeve, described sleeve pipe are seamless steel pipe.

Described drive shaft sleeve, described sleeve pipe and leading screw are made as integrative-structure.

Described drive shaft sleeve, described leading screw pore is made as diagonal angle length less than the square hole of casing inner diameter.

Owing to adopt described technological scheme, the utlity model has following beneficial effect:

Drive shaft sleeve described in the utility model is after being set on the corresponding square transmission shaft, can be in transmission shaft transfer function power, the feed screw nut that utilizes silk to be connected on the leading screw is used the rotating force that the transmission shaft axle body produces, namely drive corresponding other objects by the feed screw nut that carries out rectilinear translation along leading screw and move, thereby reached the purpose that in transmission shaft transfer function power, can also drive other respective objects actions.

[embodiment]

Can explain in more detail the utility model by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

1～2 described drive shaft sleeve by reference to the accompanying drawings, described sleeve comprises sleeve pipe 1, leading screw 2 and feed screw nut 3; Described sleeve pipe 1 is seamless steel pipe, and have three at least, wherein, per two adjacent sleeve pipes 1 all are fixed and welded together by a leading screw 2, namely are fixed together by first sleeve pipe 1, the first rhizoid thick stick 2, second sleeve pipe 1, the second rhizoid thick stick 2, the 3rd sleeve pipe 1 such order; In addition, the shaft axis of three sleeve pipes 1 after the connection and the shaft axis of two rhizoid thick sticks 2 are overlapping, and all sleeve pipes 1 and leading screw 2 after namely being fixedly connected with all are positioned at same shaft axis, thereby are convenient to described sleeve correspondence is socketed on the axle body of relevant square transmission shaft; As required, described sleeve pipe 1 can be made as three of unexpected misfortune, and long sleeve pipe 1 two ends are fixed and welded together by the sleeve pipe 1 of a leading screw 2 with other two weak points respectively, and namely the order by short sleeve 1, the first rhizoid thick stick 2, long sleeve pipe 1, the second rhizoid thick stick 2, short sleeve 1 is fixedly connected with; Perhaps, described sleeve pipe 1 and leading screw 2 can be made as an overall structure;

Described leading screw 2 is tubulose, the outer wall silk of leading screw 2 is connected to a feed screw nut 3, be that leading screw 2 is when rotating with transmission shaft in position, feed screw nut 3 is can be by the outer silk ribbon of leading screw 2 thick stick bodies moving and carry out traveling priority along the thick stick body of leading screw 2, drives the purpose that other corresponding objects carry out traveling priority thereby reached when the square transmission shaft rotates; Simultaneously, the external diameter of leading screw 2 coincide corresponding with the external diameter of sleeve pipe 1, for the axle body of avoiding transmission shaft rubs when rotated and between sleeve pipe 1 inwall, the pore 4 of leading screw 2 can be made as diagonal angle length less than the square hole of sleeve pipe 1 internal diameter, and the square hole of all leading screws 2 all coincide corresponding, namely be arranged at square hole in the leading screw 2 after all leading screws 2 are fixedly connected with, four equal correspondences in angle of each square hole are in identical angle, thereby not only be beneficial to socket square transmission shaft, but also firmly the square transmission shaft is positioned at described sleeve inner by these corresponding square holes, reached the purposes that when the square transmission shaft rotates, drive smoothly sleeve pipe 1 and leading screw 2 synchronous rotations.

When implementing described drive shaft sleeve, only described jacket casing need be connected on it the relevant square transmission shafts, and make described sleeve be fixed in the relevant position of transmission shaft axle body, what require wherein that the axle body of square transmission shaft can coincide is interspersed in the pore 4, namely is beneficial to drive described sleeve by the square transmission shaft rotate after clamping; According to actual conditions, the outer wall of feed screw nut 3 is fixed together with needing accordingly mobile object, when the square transmission shaft rotates, just can drive corresponding object by feed screw nut 3 and carry out traveling priority, it should be noted that, the distance that respective objects moves should be with the rotating cycle of square transmission shaft certain ratio, namely can control the displacement distance of respective objects in practical operation by the rotating cycle of control square transmission shaft; In addition, as required, outer silk can be set in the axle body relevant position of round transmission shaft directly, and silk place silk connects corresponding feed screw nut 3 outside, thereby directly utilize the feed screw nut 3 that rotarily drives of round transmission shaft to carry out traveling priority; Under special circumstances, if transmission shaft is set to many ribs type transmission shaft, be the transmission shaft of orthohexagonal hexagon such as the cross section, then need the pore 4 of tubulose leading screw 2 is set to the polygonal hole corresponding with the transmission shaft axle body, thereby satisfy the purpose that rotarily drives described sleeve of utilizing transmission shaft.
