Coupling belongs to mechanical spare part in common use category, and two axles (driving shaft and driven shaft) be used in connection different institutions make it jointly to rotate with the mechanical parts of transmitting torque.In the power transmission of high-speed overload, some coupling also has the effect of buffering, vibration damping and raising axle system dynamic performance.Coupling is made up of two halves, connects respectively with driving shaft and driven shaft.General power engine is mostly connected by means of coupling and working machine, is the most frequently used connected element of engineering goods axle system transmission.
Coupling supports the use in various different main computer boxes, working environment more complicated around, as situations such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, aggressive medium, salt solution, radiation, one of key factor must considered when being and selecting coupling.First should selecting suitable type according to job requirement during coupling selection of a great variety, then according to diameter calculated torque and the rotating speed of axle, then from about finding applicable model handbook, finally necessary checking computations being done to some vital part.Coupling reaches without backlash transmitting torque mainly through pretension, and axle connects without backlash, good pliability and impact resistance, allows the skew of all directions, even if at high speeds, motion is also steady, can bear large workload.
The mode that existing coupling adopts profile of tooth to engage mostly combines, and adopts the mode of key transmission to connect driving shaft and driven shaft.Have drive gap unavoidably, cause the synchronism of driving shaft and driven shaft to decline.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of high synchronism coupling, by clamping bolt and tightening nut, driving shaft and driven shaft are fixed on shaft coupling pipe inside, and overlap flexible boot outward at clamping bolt, two springs are set in shaft coupling pipe, to reduce the drive gap of this coupling.
For achieving the above object, the utility model provides following technological scheme:
A kind of high synchronism coupling, it is characterized in that: described high synchronism coupling comprises the cylindrical shape shaft coupling pipe of both ends open, shaft coupling pipe inside center place is provided with dividing plate, shaft coupling pipe is divided into the region that two grades in left and right are large by dividing plate, the center, the left and right sides of dividing plate is all fixed with measure-alike spring, the left and right sides of shaft coupling pipe are equipped with the bolt hole that at least two run through shaft coupling pipe, be equipped with clamping bolt and the tightening nut of mutual screw-thread fit in each bolt hole, each clamping bolt all overlaps a columnar flexible boot.
Preferably, described shaft coupling pipe and dividing plate are by carbon, C steel making, and shaft coupling pipe and dividing plate are monolithic construction.
Preferably, described spring is the spring steel manufacture of 60Si2Mn by the trade mark, and spring surface is coated with one deck zinc alloy.
Preferably, the size of described each bolt hole is equal, and the shaft axis of bolt hole all passes perpendicularly through the axis of shaft coupling pipe.
Preferably, described flexible boot is manufactured by rubber, and the length of flexible boot equals the outer diameter length of shaft coupling pipe.
The beneficial effect of above technological scheme is adopted to be: the center, the left and right sides of the dividing plate of this high synchronism coupling is all fixed with spring, the left and right sides of shaft coupling pipe are equipped with at least two bolts hole, be equipped with clamping bolt and tightening nut in each bolt hole, each clamping bolt all overlaps flexible boot.Bore at driving shaft and driven shaft corresponding position during use and open bolt through-hole, and ensure flexible boot and this bolt through-hole interference fit, prevention drive gap.Driving shaft and driven shaft are filled in respectively two end entrances of shaft coupling pipe, and insert clamping bolt, fix with tightening nut, due to the spring pre-tightening effect of dividing plate both sides, driving shaft and driven shaft is made to be subject to toward the pretightening force effect outside shaft coupling pipe, increase the laminating tightness degree of clamping bolt and driving shaft and driven shaft, effectively reduce drive gap, maintain the high synchronism of this coupling.
