Abstract

The utility model discloses a combined type elastic pin coupling, comprising a driving shaft inserting block (1), a driven shaft inserting block (3), and a spring pin (2). The both sides of each driving shaft inserting block (1) and driven shaft inserting block (3) are respectively provided with a groove, and the spring pin (2) is arranged between the groove of the driving shaft inserting block (1) and the groove driven shaft inserting block (3). The utility model is suitable for the connection of the regular positive and negative rotations and the frequent starting; under the function of the variable load, the combined type elastic pin coupling can transmit the torque moment within the large range and an occasion without oil pollution.

Description

Combined type elastic pin coupling

Technical field under the utility model: engineering part

At present, be used for the frequent clockwise and anticlockwise of the connection of diaxon on the machine, starting is frequent, normally elastic ring column pin shaft coupling and nylon pin coupler etc. of the coupling of transmitting torque under varying load effect.The elastic ring of elastic ring column pin shaft coupling is in use easy to wear, wearing and tearing backs pin unbalance stress, be easy to generate loosening cause connecting damage, thereby working life is not long, its buffering vibration absorption ability and to compensate the misalignment of axe ability high and overall sizes is bigger.Nylon pin coupler reliability is higher, and working life is long but vibration damping and compensation axis excursion capability be it would be better elastic ring column pin shaft coupling.

The utility model is to overcome a kind of New Model of Flexible Coupling that the shortcoming of above-mentioned coupling designs.

The utility model is the formula resilient key coupling of inserting, as shown in drawings.In the accompanying drawing: (1) is that driving shaft is inserted, and (2) are resilient keys, and (3) are that driven shaft is inserted.Driving shaft insert (1) be connected initiatively on the axle housing with pin and screw, driven shaft insert (3) be connected on the driven axle housing with pin and screw, driving shaft is inserted (1) and driven shaft is inserted, and (3) respectively have several piece.The quantity of inserting can be decided according to actual demand, normally respectively has three, totally six.Insert (1) and the insert both sides of (3) of driven shaft have a groove at every driving shaft, the groove and the driven shaft of insert at driving shaft (1) inserted and between the groove of (3) resilient key (2) is housed.If groove semicircle camber, then resilient key (2) is a cylinder type.The torque of driving shaft is inserted (1) by driving shaft, resilient key (2), driven shaft insert (3) pass on the driven shaft.

The formula resilient key coupler structure compactness of inserting of the present utility model, in light weight, volume is little, have fabulous mitigation and impact, absorb vibration performance and bigger compensation misalignment of axe ability, the steady noise that turns round is little, safe and reliable, long service life.And easy to maintenance, mobile apparatus equipment is promptly not detachable.Also can utilize pad to regulate to insert axial length or radial height to satisfy matching requirements.

Coupling of the present utility model is applicable to and connects frequent forward and backward that starting is frequent, the occasion of transmitting torque and no greasy dirt under varying load effect.General large, medium and small type compressor, ventilator, blower, water pump, centrifugal pump, screw conveyor, adhesive tape conveyor, noria and mine, construction machine etc. are all applicable.
