Technical field

The utility model relates to grinding equipment technical field, is specifically related to a kind of elastomer diaphragm coupling for pebble mill.

Background technique

In industrial production technology field, pebble mill is used for primary raw materials, as ore, carries out the machinery of high fine lapping.In ball mill equipment, coupling is used for the transmission device be connected with frequency conversion control motor-driven by gearbox.Coupling for pebble mill has two kinds, and one is pin type coupler, and another is diaphragm coupling.

Wherein, pin type coupler two half-couplings is coupled together formation by pin, pin coupler requires the necessary strict centering of diaxon be connected, only allow very little radial displacement and tilting tolerance, also namely require higher to the coaxality of pebble mill position structure, add difficulty of processing and the assembling difficulty of each assembly of pebble mill, also the operational reliability of corresponding reduction pebble mill.

If publication number is the Chinese patent literature of CN204437100U, buffer shock-absorbing ability for pin gear coupling, the easy impact fatigue transmission failure of nylon pin, a kind of pebble mill highly elastic shaft coupling is disclosed on the larger technical problem of normal production and operation impact, it comprises left back-up ring, coupling axle tooth, coupling overcoat, spacer, nylon pin, right back-up ring, half-coupling, attachment bolt and elasticity blob of viscose, left back-up ring is fixedly mounted on coupling overcoat left side by attachment bolt, keyway is processed with in coupling axle tooth center hole, the each tooth the same side of coupling axle tooth is installed with elasticity blob of viscose, be rectangular inner meshing gear in coupling overcoat left end endoporus and engage with coupling axle tooth, be pin flute profile in coupling overcoat right-hand member endoporus, nylon pin is arranged in coupling overcoat and half-coupling teeth groove, spacer is arranged on left side in coupling overcoat right-hand member hole and its right side withstands on half-coupling left side, half-coupling center hole is processed with keyway, right back-up ring is fixedly mounted on coupling overcoat right side and its left side by attachment bolt and is pressed on nylon pin right side.This pebble mill highly elastic shaft coupling easy installation and removal, has overload protection and buffer shock-absorbing effect, reduces the technique effect impacting resonance.But this pebble mill highly elastic shaft coupling still exists the coaxality requirement of pebble mill position structure higher, the difficulty of processing of each assembly of pebble mill and assembling difficulty, the technical problem of the operational reliability difference of pebble mill.

Diaphragm coupling comprises two half-couplings with tie-plate and the diaphragm be arranged between two half-couplings, on each half-coupling, equal correspondence offers the half-coupling center hole with keyway, tie-plate all offers many coupling bolt holes, two half-couplings is coupled together formation diaphragm coupling by attachment bolt staggered connection.Diaphragm coupling is the relative displacement being compensated joined diaxon by the resiliently deformable of diaphragm, thus reduces the coaxality requirement to pebble mill position structure.Simultaneously also to have structure compacter for diaphragm coupling, and gap without spin, the advantages such as intensity is high, need not lubricate, and acid resistant alkali Corrosion Protection is good, it is applied to the axle system transmission of various machinery more and more.

Existing diaphragm coupling, its diaphragm folds the rigid membrance of collection by several pieces Stainless Sheet Steels.Because pebble mill is heavy-duty drive system, for the diaphragm coupling of pebble mill, its diaphragm is coupling the most core, the parts that the most easily consume, and the cost of diaphragm is close to 1/2nd of coupling cost.Because the contact between rigid membrance and two half-couplings is rigid contact, therefore need during assembling to carry out levelling capturing accurately, improve the quality of fit between diaphragm and two half-couplings, when quality of fit is very high, being interlocked by attachment bolt, to connect the operation easier that is fixedly connected with by two half-couplings very high.In using, attachment bolt easily loosens, and after pebble mill work a period of time, needs to check whether attachment bolt loosens, loosens, need attachment bolt to tighten if there is attachment bolt.Tooth punching can be caused to wear and tear because attachment bolt loosens, if attachment bolt can not be tightened in time, tooth punching heavy wear can be caused.Therefore there is the higher technical problem of rate of fault in the coupling of rigid membrance, and it can directly cause the transmission system of pebble mill to lose efficacy, and causes larger adverse effect to normal production and operation, also greatly can increase the line service amount of pebble mill simultaneously.

In sum, relative to pin type coupler, resiliently deformable by diaphragm compensates the relative displacement of joined diaxon, the rigid membrance coupling that the coaxality significantly reducing pebble mill position structure requires, assembly precision requires very high, assembling difficulty is large, running check bolt tightening degree is needed in using, once bolt looseness will tight a bolt, otherwise meeting tooth punching heavy wear, causes the ineffectiveness fault of coupling, and then directly causes the transmission system of pebble mill to lose efficacy, larger adverse effect is caused to normal production and operation, increases the user cost of coupling.
