Abstract
The invention provides a shear spring, which belongs to the field of general mechanical components and is designed for overcoming the deficiency that the prior rubber shear spring is low in strength and poor in bearing capacity. A main body of the shear spring is a cylinder which is made from nonmetal elastic materials and is provided with a hole in the middle; two metal installation claw discs are pre-embedded inside a spring body near two end faces of the spring body; the installation claw discs are provided with threaded holes for installation and use; the two installation claw discs are connected together through a safety steel wire ring; and two ends of the installation claw discs are fixed by positioning pins. The shear spring has the characteristics of convenient installation, safe reliable use and long lifespan, and can be widely applied to vibrating-screening or feeding machines or other equipment with high acting force and vibration intensity in industrial and mining enterprises.
Description
Technical field
The invention belongs to the universal machine field of components, mainly relate to have the shear spring of higher-strength and Security.
Background technique
The existing rubber shear spring that uses generally is that the two ends with the rubber spring body are stained with connecting plate, or is molded into connecting plate, is fixed on the corresponding workpiece by connecting plate.Also the two ends of rubber spring body can be placed in the pit of connecting plate, be fixed on the corresponding workpiece by connecting plate.Because this Placement is not very firm, rubber intensity neither be very high in addition, do not reach the less occasion of ocsillator strenght so can only be applied to light-duty, active force very much.If when active force and ocsillator strenght were big, this kind shear spring was just inapplicable.
Summary of the invention
The purpose of this invention is to provide a kind of shear spring, this shear spring and can guarantee the Security and life-span of using effectively when improving its intensity.
The present invention is achieved by the following measures, mainly is made up of spring main body, mounting disc and safe becket bridle.The spring body of shear spring is by non-metallic elastic material making, middle porose cylindrical body; In the inside of spring body,, be embedded with two metal mounting jaw dishes near near the both ends of the surface; Be processed with the tapped hole of installing and using on the mounting jaw dish; Two mounting jaw dishes link together by the safety lanyard ring, and two ends are fixed by locating stud.The safety lanyard ring is to be made by multistrand rope, and bending two ends is collar shape, and is middle by the locking of compacting joint.Spring body is to be made by the polyurethane material of intensity height, good springiness, in order to be connected firmly, is processed with groove or columnar protrusions on the circumference of embedded part mounting jaw dish and the end face, increases the surface of contact with polyurethane.The horizontal end face of shear spring main body can be circular, square or rectangular.When shear spring uses, with connecting bolt two end faces of spring are connected with parts accordingly and get final product.When equipment availability meets accident, during the shear spring fracture,, can avoid the generation of security incident owing to the effect of safety lanyard ring.
The invention has the beneficial effects as follows that shear spring can be installed on the equipment by pre-buried mounting jaw dish and bolt easily, the safety lanyard ring can prevent effectively that the unexpected fracture of spring back from equipment accident taking place.Be specially adapted to the bigger equipment of active force and ocsillator strenght.Have characteristics easy for installation, safe and reliable and that the life-span is long.Can be widely used in the equipment such as the vibrosieve of industrial and mining enterprise or distributor.
Description of drawings
Fig. 1 is structural representation of the present invention (comprises signal is installed), and Fig. 2 is the schematic representation of safety lanyard ring, and Fig. 3 is a shear spring main body view, and Fig. 4 is the left view of Fig. 3.
Among the figure 1 be spring body, 2 for the safety lanyard ring, 3 for the mounting jaw dish, 4 for locating stud, 5 for construction bolt, 6 for the parts that are connected with spring, 7 for wire rope compacting joint, 8 be that wire rope, 9 is the tapped hole on the mounting jaw dish.
Embodiment
Existing accompanying drawings embodiments of the present invention, shear spring body 1 is by polyurethane material moulding, middle porose cylindrical body, and inner close two end faces is embedded with the mounting jaw dish 3 of two metals, is processed with the tapped hole of installing and using 9 on the mounting jaw dish 3; Be processed with the groove or the columnar protrusions that can increase on circumference and the end face with the polyurethane spring contact level.Two mounting jaw dishes 3 link together by safety lanyard ring 2, and two ends are fixing by locating stud 4.Safety lanyard ring 2 is to be made by multistrand rope 8, and bending two ends is collar shape, and is middle by 7 lockings of compacting joint.When shear spring uses, with connecting bolt 5 two end faces of spring are connected with parts 6 accordingly and get final product.
