Abstract
The utility model provides a transmission shaft with cambered counterweight blocks. The transmission shaft comprises a transmission shaft body, wherein three cambered counterweight blocks are arranged at the free end of the transmission shaft body; two radial counterweight grooves and an axial counterweight groove are formed on the transmission shaft body, respectively; four threaded holes are formed in each radial counterweight groove and each axial counterweight groove; four through holes corresponding to the threaded holes one to one are formed on each cambered counterweight block, wherein one cambered counterweight is fixed in the axial counterweight groove through a screw by tightening, and the other two cambered counterweight blocks are fixed in the two radial counterweight grooves through screws by tightening; in other words, the two cambered counterweight blocks are arranged in the radial direction of the transmission shaft body, while the another cambered counterweight block is arranged in the axial direction of the transmission shaft body. The transmission shaft with the cambered counterweight blocks provided by the utility model is high in rotational inertia and high in rotating speed during rotation.
Description
Technical field:
The utility model relates to the transmission part on a kind of machinery, specifically is a kind of transmission shaft that arc is joined piece that disposes.
Background technique:
In some machinery, need transmission shaft to move in a circle around self center of circle, this just needs external driver device constantly to the transmission shaft application of force, existing transmission shaft, its weight is equally distributed, can't in the transmission shaft rotation process, produce extra assistance force, cause this transmission shaft when circular movement, need external driver device that it is applied larger power, and need to keep this larger power just can keep transmission shaft always and constantly rotate, and the rotating speed of transmission shaft is not high.
The model utility content:
The technical problems to be solved in the utility model is, rotary inertia was larger when a kind of rotation was provided, and rotating speed is higher disposes the transmission shaft that arc is joined piece.
Technical solution of the present utility model is that a kind of transmission shaft that arc is joined piece that disposes with following structure is provided: comprise the transmission shaft body, wherein, the free end of transmission shaft body is provided with several arcs and joins piece.
Described in the utility modelly dispose the transmission shaft that arc is joined piece, wherein, several arcs are joined radial direction and the axial direction that piece is located at respectively the transmission shaft body.
Described in the utility modelly dispose the transmission shaft that arc is joined piece, wherein, be respectively equipped with radially counterweight groove and axially counterweight groove on the transmission shaft body, each is counterweight groove and axially be equipped with several tapped holes in the counterweight groove radially, each arc is joined piece and is provided with and each tapped hole through hole of corresponding setting one by one, and several arcs are joined piece and screwed by screw respectively and be fixed in radially the counterweight groove and axially in the counterweight groove.
After adopting above structure, compared with prior art, the utility model disposes arc and joins the transmission shaft of piece and have the following advantages: be provided with arc at the free end of transmission shaft body and join piece, it is heavier that arc is joined the weight ratio of piece, the weight of transmission shaft ontological idea of freedom end is increased, when the transmission shaft body rotates, because arc is joined the effect of piece, cause the rotary inertia of transmission shaft body to increase, at this moment external drive device just applies less power the utility model and disposes arc and join the transmission shaft of piece and just can obtain larger rotating speed.
Several arcs are joined radial direction and the axial direction that piece is located at respectively the transmission shaft body, can arc be set in a plurality of positions and join piece, the convenient adjusting.
Arc is joined piece and is installed in the radially counterweight groove and axial counterweight groove of transmission shaft body by screw, and this mounting type can make installation and removal very convenient.
Description of drawings:
Fig. 1 is that the utility model disposes the main TV structure schematic diagram that arc is joined the transmission shaft of piece;
Fig. 2 is that the utility model disposes arc and joins the structure for amplifying schematic diagram that arc in the transmission shaft of piece is joined piece.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model being disposed arc joins the transmission shaft of piece and is described in further detail:
As depicted in figs. 1 and 2, in this embodiment, the utility model disposes arc and joins the transmission shaft of piece and comprise transmission shaft body 1, the free end of transmission shaft body 1 is provided with three arcs and joins piece 2, be respectively equipped with two radially counterweight groove 4 and axial counterweight grooves 3 on the transmission shaft body 1, each is counterweight groove 4 and axially be equipped with four tapped holes in the counterweight groove 3 radially, each arc is joined and is equipped with on the piece 2 and each tapped hole four through holes 5 of corresponding setting one by one, one of them arc is joined piece 2 and is screwed by screw and be fixed in the axial counterweight groove 3, two other arc is joined piece 2 and is screwed by screw respectively and be fixed in two radially in the counterweight groove 4, that is to say that described two arcs join the radial direction that piece 2 is located at transmission shaft body 1, the another one arc is joined the axial direction that piece 2 is located at transmission shaft body 1.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model; the quantity of joining piece 2 such as arc can increase and decrease as required; arc is joined piece 2 can be four, five etc., all should fall in the protection domain that the utility model claims determine.
