Abstract
The utility model discloses an eccentric block connecting structure which comprises two eccentric blocks in the same size, wherein two shaft holes which are in tight fit with a rotation shaft are respectively formed in the surfaces of the two eccentric blocks, a ring gasket which is in the same center of a circle is padded between the two shaft holes, corresponding communicated countersunk bolt holes are formed in the other side of the shaft holes in the two eccentric block, and bolts are installed in the corresponding countersunk bolt holes. When the eccentric block connecting structure is installed, the two eccentric blocks and the gasket are installed on a transmission shaft in a tight fit way, then the bolts are tightened, the two eccentric blocks are tightened, and the eccentric block connecting structure is fastened on the rotation shaft through radial force generated by tightening the two eccentric blocks in a slant way and friction of the two eccentric blocks, so that the eccentric blocks are prevented from generating axial displacement and rotary displacement, thereby smoothly completing the transmission of torque. The eccentric block connecting structure has the advantages of simple structure, convenience in processing and use and low cost.
Description
Technical field:
The utility model relates to vibrating machine, the eccentric mass linkage structure of particularly installing on a kind of vibrating motor and the vibrator.
Background technique:
Eccentric mass Placement on vibrating motor or the vibrator has two kinds at present, and a kind of is to be fixed with key in the joint of eccentric mass and axle, and another kind is to have slotted eye at eccentric mass, clamps with bolt in slotted eye.The shortcoming that this dual mode exists is processing, dismounting, it is all cumbersome to install, and cost is raise.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, processing, dismounting and install all more convenient, the eccentric mass linkage structure that cost is low.
The technical solution of the utility model is finished as follows, it includes two eccentric masss that size is identical, it is characterized in that: be respectively equipped with one and the friction tight axis hole of rotatingshaft at two eccentric mass faces, concentric is lined with an annulus pad between two axis holes, be provided with the flush bolt hole that a correspondence communicates at two eccentric mass upper shaft hole opposite sides, a bolt is installed in the flush bolt hole of correspondence.During installation two eccentric masss and pad drive fit are installed on the transmission shaft, then tight a bolt, with two eccentric mass tensions, by two radial force and frictional force thereof that the oblique tension of eccentric mass produces, be fastened on the rotatingshaft, prevent that eccentric mass from producing axial displacement and swing offset at axle, thereby finish smoothly transfer of torque to have advantages of that simple in structure, processing, cost easy to use are low.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, the utility model is to be respectively equipped with one and the friction tight axis hole 1 of transmission shaft at two 3 identical of eccentric masss of size, concentric is lined with an annulus pad 2 between two axis holes, be provided with the flush bolt hole that a correspondence communicates at two eccentric mass upper shaft hole opposite sides, in the flush bolt hole of correspondence, be furnished with a bolt 4.
Its working principle is: the axis hole periphery between two eccentric masss is set up an annulus pad, when when the eccentric mass opposite side is strained with bolt, pad produces equal-sized pressure opposite to bolt tension force to eccentric mass, make eccentric mass produce deflection, distribute thereby between the axis hole of eccentric mass and axle, produce asymmetric radial force, form a pair of balance couple.The frictional force that these radial forces produce can stop to axial displacement and the swing offset of axle and eccentric mass, reaches the purpose of safe transfer moment of torsion.
