Abstract

The utility model relates to a strong elastic coupling, which is characterized in that a left half coupling is fixed with a plurality of pin shafts uniformly distributed. The pin shafts are sheathed with floating sleeves, and the outer sides of the floating sleeves are sheathed with elastic rings. A right half coupling is provided with a plurality of circular arced slots uniformly distributed, and simultaneously, the right half coupling is fixed with a baffle through a bolt. The utility model has the advantages of gear couplings and elastic couplings, and has the advantages of simple fabrication and low cost.

Description

The strong elastic coupling

The utility model belongs to coupling member commonly used in the mechanical transmission.

Coupling commonly used in the mechanical transmission has fixed and compensation.Be divided into rigidity and flexible two classes in the compensation coupling again, its kind is more, uses extensively.But present compensation coupling remains in the some shortcomings part: as belong to the gear coupling of category of rigid, and the bearing capacity height has bigger compensating action to the skew deflection in the installation and operation; But it makes complicated, cost height, and not buffering and absorbing effect.For another the elastic ring column pin shaft coupling that belongs to elastic type, there is absorbing preferably slow neutral, certain compensating action is also arranged; But its elastic ring adopts rubber material, and the low life-span of bearing capacity is short, and when transmitted power was big, coupling was oversize.

The purpose of this utility model provides a kind of novel strong elastic coupling, and it combines the advantage of existing compensation coupling, and has overcome its deficiency: i.e. and bearing capacity height, compensation performance and buffer function are preferably arranged, and it is low to make simple cost.

Fig. 1 is the enforcement ssembly drawing of strong elastic coupling, and Fig. 2 is the left view of Fig. 1.Fig. 3, Fig. 4 are respectively the partial enlarged drawing behind the coupling prestart.

As shown in Figure 1, it is by left half a coupler 1, bearing pin 2, floating bushing 3, elastic ring 4, the right side Half a coupler 5 and plate washer 6 form.

If be fixed with in uniform bearing pin 2 on the half-coupling 1 of a left side, be with floating bushing 3 on the bearing pin 2, floating bushing 3 outsides are overlapped with elastic ring 4 again.On half shaft coupling 5 of the right side, be processed with some uniform garden arc grooves, with bolt plate washer 6 arranged simultaneously.Left half-coupling assembly (1,2,3,4) is packed on the right half-coupling 5 in the arc groove of garden together, and the effect of plate washer 6 is the axial floats that prevent floating bushing 3 and elastic ring 4.A left side half-coupling 1 and right half-coupling 5 link up with the axle of institute transmission respectively by center hole and key.

During transmission, drive left half-coupling 1, promptly, active force is passed to bearing pin 2, rotate thereby drive right half-coupling 1 by floating bushing 3, elastic ring 4 by the garden arc groove on the right half-coupling 5 by right half-coupling 5.

As shown in Figure 3, because center when elastic ring 4 is enclosed within the outside of floating bushing 3, pressed to all floating bushings 3 greater than the diameter of axle of bearing pin 2 in the aperture of floating bushing 3, and form the eccentric distance e between floating bushing 3 and the bearing pin 2.Simultaneously floating bushing 3 remains gap value δ with garden arc bottom land on the right half-coupling 5, and this gap amount is the radial compensation amount of the minimum that has of this coupling, i.e. the amount of floating up and down that allows of coupling.

The nose balance amount is determined by the axial displacement that left half-coupling 1 and right half-coupling 5 allow.

In addition, because floating bushing 3 outer gardens are cydariform, make this coupling have bigger deflection (corner) compensation rate.

During this coupling starting good buffer function being arranged, is because it has the two-stage elastic element, i.e. elastic ring 4 and floating bushing 3.As shown in Figure 4, when starting, garden arc groove is pressed to floating bushing 3 on the right half-coupling 5, make it turn over an angle [alpha] around bearing pin 2, active force is passed to elastic ring 4, and at first elastic ring 4 produces bigger distortion, and then floating bushing 3 also produces certain distortion, finish buffering course thereby absorb energy, enter normal operation then.

The utility model compared with prior art has following advantage:

1, extensive applicability is arranged, can replace each veriety in the existing compensation coupling, be convenient to organize specialized production.

2, its performance is equivalent to elastic coupling flexible coupling, have good buffer function, and bearing capacity is equivalent to gear coupling, has bigger compensating action.Because of it all adopts metal construction, thus traditional elastic coupling flexible coupling surpassed working life, and manufacturing process is simple, and cost of production is lower than gear coupling.

3, simple in structure, size is little, is easy to make.
