Abstract
The invention provides a combined type rubber torsion spring which comprises elastic blocks and a torsion assembly. The torsion assembly comprises a cross supporting base and steel plates, wherein the cross supporting base is a cross planar stretching body; the four steel plates are sequentially connected to form a square barrel; the cross supporting base is arranged in a barrel cavity of the square barrel; the cross supporting base and the square barrel define four square cavities; and the elastic blocks are four rubber blocks. The combined type rubber torsion spring provided by the invention has the beneficial effects that: firstly, elastic force is adjustably; secondly, relatively great torsion moment and a relatively great torsion angle can be borne; thirdly, the service life is long; and fourthly, combination is convenient, the combined type rubber torsion spring is easily matched with various occasions for use, and can be manufactured into a combined type guide connecting rod spring, a combined type damping spring and the like through different combinations.
Description
Technical field
The present invention relates to flexible member is and in particular to a kind of torsionspring of long service life.
Background technology
The torsionspring using at present has Steel coil torsion spring and two kinds of shearing torsion rubber spring.It is to be acted on by twisting resistance in helical spring two ends steel wire that Steel coil reverses spring, leads to spring to be deformed and produces elasticity of torsion power；Shearing torsion rubber spring is to bear twisting resistance by the metal steel pipe being bonded in cylindrical rubber surfaces externally and internally and forms rubber detrusion and form elasticity of torsion power, a kind of torsion rubber spring for mechanical suspension seat as described in number of patent application 2015202510460.
Technical problem：Both the above torsion spring only can be used in specific occasion, and the occasion for big torque, big corner is less applicable, and mounting means is also restrained.Steel coil torsionspring is typically used only in the less occasion in space, and the torsion born is also smaller；Shear-type rubber spring requires to compare high to the bonding technology of rubber and metal, the phenomenon such as easily bonding fault rupture in use, comes off, service life is short.
Content of the invention
The present invention overcomes the shortcomings of that background technology provides a kind of combined rubber torsionspring, and purpose of design is：This torsionspring can bear larger twisting resistance；This torsionspring possesses higher service life.
The invention provides following technical proposals：A kind of combined rubber torsionspring, including elastomer block, reverses assembly.Described torsion assembly includes cross bearing, steel plate, described cross bearing is the extrusion of cruciform plan, described steel plate is four, the described steel plate of four is sequentially connected and surrounds square tube, described cross-shaped seating is in the into the barrel chamber of described square tube, described cross bearing and described square tube surround the square chamber of four, and described elastomer block is the block rubber of four, and the described elastomer block correspondence of four inserts described side's intracavity of four.
The upper and lower ends fixed connector limiting plate of described cross bearing.
Beneficial effects of the present invention are as follows.Combined rubber reverses spring when being subject to twisting resistance, and what the elastomer block 1 of rectangular quality of rubber materials was born is the described square tube compression stress relative with cross bearing 2, and the torsionspring comparing aforementioned two kinds of forms has the advantage that：First, elastic force can adjust, and shell steel plate is different to the pre compressed magnitude of elastomer block, and during rotation, required moment of torsion is also different, admittedly the torsional moment of combination twisting spring can be adjusted by adjusting the pre compressed magnitude of elastomer block 1；Method of adjustment is in advance square tube and cross bearing 2 to be carried out reversing in a pre-installation installing.Itself just carries certain twisting resistance, referred to as pre compressed magnitude after mounting.2nd, adopt the elastomer block 1 of four, larger torsional moment and windup-degree can be born；3rd, long service life, compression is little to rubber internal structural damage compared with shearing；4th, combine conveniently it is easy to multiple occasions support the use, various combination can be passed through, make Combined guide to rod spring, combined damping spring etc..
Brief description
Fig. 1 is a kind of structural representation of combined rubber torsionspring.
Fig. 2 be in Fig. 1 A-A to sectional view.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described with specific embodiment.
Fig. 1, in 2：Elastomer block 1, cross bearing 2, steel plate 3, limiting plate 4, arrow B are torsion force direction, arrow C is elastic force direction.
A kind of combined rubber torsionspring, including elastomer block 1, reverse assembly, described torsion assembly includes cross bearing 2, steel plate 3, described cross bearing 2 is the extrusion of cruciform plan, and described steel plate 3 is four, and the described steel plate 3 of four is sequentially connected and surrounds square tube, described cross bearing 2 is placed in the into the barrel chamber of described square tube, described cross bearing 2 and described square tube surround the square chamber of four, and described elastomer block 1 is the block rubber of four, and described elastomer block 1 correspondence of four inserts described side's intracavity of four.The upper and lower ends fixed connector limiting plate 4 of described cross bearing 2.
Installation and application：First the elastomer block 1 of four is loaded onto cross bearing 2, then pierce in the barrel chamber of the square tube that four steel plates 3 surround, when installation, carry out pre torqued compression.Arrow B is torsion force direction, arrow C is elastic force direction.
