Description
Technical field
The utility model relates to vibrating machine, is specifically related to a kind of vibrating motor and vibrating machine vibration generator be installed exciting force infinitely variable eccentric block connected mode.
Background technology
The adjustment of current vibrating motor and vibrating machine exciting force of exciter, generally adopt the angle between change activity eccentric block and fixed eccentric block to realize, and the adjustment of this angle realizes conventionally by two kinds of modes.One is adjusted by spindle keyway position and movable eccentric block keyway position; Two is get through hole on fixed eccentric block and movable eccentric block, and the connection being realized diverse location hole by bolt is adjusted.But its adjust exciting force to be fixing several values, adjustable range is little, and the step-less adjustment that simultaneously can not realize exciting force accurately realizes exciting force needed for certain, cannot meet the needs in actual production, cause the waste of resource, not meet the thought of sustainable development.
Summary of the invention
The purpose of this utility model is the weak point overcome in prior art, provides the exciting force infinitely variable eccentric block jockey that a kind of structure is simple, easy to adjust, effective, meet different operating mode needs.
For achieving the above object, exciting force infinitely variable eccentric block jockey of the present utility model, comprise rotating shaft, fixed eccentric block and movable eccentric block, described fixed eccentric block is fixed on the construction section of rotating shaft shoulder by key, the end that described movable eccentric block and gland matched in clearance are arranged on fixed eccentric block puts, the both sides of gland are provided with the bolt be fixed on movable eccentric block, middle part is provided with the holding screw being fixed on fixed eccentric block end and putting, movable eccentric block is connected with fixed eccentric block, can do 360 degree of rotations; Rotating shaft is provided with the round nut that axial locking fixes movable eccentric block.
Length 1 ~ the 3mm fewer than the thickness sum of two eccentric blocks of described rotating shaft construction section.
The end cover outer surface of described fixed eccentric block there is the decorative pattern through annular knurl process.
The gap that described gland coordinates with movable eccentric block is 1-2mm, the few 2-4mm of thickness of the movable eccentric block of Thickness Ratio of gland.
Beneficial effect: owing to have employed technique scheme, the utility model overlaps annular knurl process, to improve its skin-friction coefficient by the end outstanding to fixed eccentric block; Gland makes incomplete semicircle, to compressing a series of measure of holding screw left on gap and gland, completing and locking the radial direction of movable eccentric block.The length of rotating shaft construction section is less than the thickness sum of two eccentric blocks, gap is left to the axial locking of round nut, the axial locking to movable eccentric block can be completed well, this connected mode can well be connected as a single entity fixed eccentric block and movable eccentric block, and 360 degree of rotations of realization activity eccentric block.When needing to regulate exciting force, only need looser a bolt, holding screw and round nut namely can rotary moveable eccentric blocks, become arbitrarily angled, carry out realize target exciting force, and do not need with the reciprocal dismounting of upper-part with fixed eccentric block, simple to operate.The step-less adjustment between maximum exciting force and minimum exciting force can be realized by movable eccentric block, while meeting the needs of actual production, improve resource utilization.

Embodiment
Below in conjunction with accompanying drawing, the embodiment that the utility model is implemented is further described:
Shown in Fig. 1 Fig. 2, exciting force infinitely variable eccentric block jockey of the present utility model, is formed primarily of rotating shaft 2, fixed eccentric block 6, movable eccentric block 1, key 8, holding screw 5, bolt 7, round nut 3, stop washer, spring washer and common plain washer.Described fixed eccentric block 6 is fixed on by key 8 on the construction section of rotating shaft 2 shoulder, shown in Fig. 5.The end that described movable eccentric block 1 and gland 4 matched in clearance are arranged on fixed eccentric block 6 puts, and the gap that described gland 4 coordinates with movable eccentric block 1 is 1-2mm, the few 2-4mm of thickness of the movable eccentric block 1 of Thickness Ratio of gland 4.The both sides of gland 4 are provided with the bolt 7 be fixed on movable eccentric block 1, and middle part is provided with the holding screw 5 being fixed on fixed eccentric block 6 end and putting, and movable eccentric block 1 is connected with fixed eccentric block 6, can do 360 degree of rotations; Rotating shaft 2 is provided with the round nut 3 that axial locking fixes movable eccentric block 1.Length 1 ~ the 3mm fewer than the thickness sum of two eccentric blocks of described rotating shaft 2 construction section; Described fixed eccentric block 6 end puts the decorative pattern (crossbar) through annular knurl process, coordinates gland 4 to be arranged on sleeve movable eccentric block 1, is screwed into holding screw 5, bolt 7, round nut 3 and other auxiliary components simultaneously.During operation, order gradation is progressively tightened (being generally 2 ~ 3 times).
Shown in Fig. 3, the constitutional diagram of movable eccentric block 1 and gland 4, can find out that gland 4 is not complete semi-circular structure, have the gap of 1-2mm with movable eccentric block 1, is conducive to gland 4 and locks the radial direction of movable eccentric block 1.The through hole 2-1 that gland 4 two ends are opened and movable eccentric block 1 liang of stomidium carry out joining brill, then to carrying out tapping, make a hole 2-2, and be convenient to locking, gland 4 top has a hole 2-3.
Shown in Fig. 4, the length of installing the diameter of axle is less than the thickness sum of two eccentric blocks, gap is left to round nut 3, be beneficial to the axial locking of round nut 3, the axial locking to movable eccentric block 1 can be completed well, this connected mode can well be connected as a single entity fixed eccentric block 6 and movable eccentric block 1, and 360 degree of rotations of realization activity eccentric block 1.When needing to regulate exciting force, only need looser a bolt 7, holding screw 5 and round nut 3 namely can rotary moveable eccentric blocks 1, arbitrarily angled with fixed eccentric block 6 one-tenth, carry out realize target exciting force.
Exciting force of the present utility model can stepless-adjustment eccentric block connected mode, concrete adjustable range can according to concrete working condition requirement, processing eccentric block, utilize mathematical computations or Virtual Prototype Technique simultaneously, calculate movable eccentric block when rotating to different angles, the different exciting forces that device provides, make nameplate, are convenient to the adjustment of exciting force in practice.Connected mode, 360 degree that can realize movable eccentric block 1 rotate freely, achieve the maximization of exciting force adjustable extent, and coupling mechanism force is not by the impact of anglec of rotation size simultaneously.Regulate during exciting force and only need unscrew holding screw 5, bolt 7 and round nut 3, rotary moveable eccentric block 1 is to specified angle.
