Abstract
The utility model discloses an elasticity pin shaft coupling, including first shaft coupling ring flange and second shaft coupling ring flange, the pin that is equipped with the pin hole, the pin includes flanged screw rod, nut and sets up respectively first nylon cover and second nylon cover in the pin hole of first shaft coupling ring flange and second shaft coupling ring flange, and first nylon cover and second nylon cover establish outside the screw rod in order. The utility model has the advantages that: the elastic part is divided into two parts, so that the elastic part can not bear shearing force any more, the impact resistance is good, the service life of the pin is prolonged, the play is small, and the abrasion is reduced.
Description
Technical field
The utility model relates to a kind of coupling, especially relates to elastic dowel pin shaft coupling.
Background technique
The pin that existing elastic dowel pin shaft coupling utilizes some nonmetallic material to make places each column pin hole on two coupling flange dishes respectively, to realize the connection of two coupling flange dishes.Because pin and column pin hole are Spielpassung, and the pin high resilience, thereby possesses the performance that compensates the diaxon relative displacement.In order to improve the adjusting that contacts of pin and column pin hole, an end of pin is made cydariform.The material of pin uses nylon 66 to make usually, and its tensile strength is greater than 54MPa, and resistance to flexure is greater than 70MPa, and compressive strength is greater than 60MPa, and shearing strength is greater than 52MPa.Its structure is simple relatively, and is easy to manufacture, and dismounting and change is convenient, does not need to lubricate, and wear resistance is preferably arranged.But nylon rod poor stability, the capacity of heat transmission are not high, and be more yielding, so reliability is not high.Because equipment is in periodically moving, motor can experience various rotation modes such as clockwise and anticlockwise, acceleration and deceleration, and this moment, coupling pin was received periodically shear stress, and pin is subjected to bigger impact force action during velocity variations, under the large impact occasion, rupture easily.
Summary of the invention
The purpose of this utility model provides the elastic dowel pin shaft coupling that a kind of anti-shearing force is strong, be difficult for taking place fracture.
Technical solution of the present utility model is: a kind of elastic dowel pin shaft coupling, comprise the first coupling flange dish that is provided with column pin hole and the second coupling flange dish, pin, described pin comprises flanged screw rod, nut and is separately positioned on first nylon jacket and second nylon jacket in the column pin hole of the described first coupling flange dish and the second coupling flange dish, and first nylon jacket and second nylon jacket are set in outside the screw rod in turn.Two nylon jacket are set outside bolt, so, elastic component is divided into two parts, two interior interior elastic components of each column pin hole of coupling flange dish no longer bear shearing force, shearing force changes by metal bolts bears, improved the shear resistance of pin, prolonged the working life of spring column pin, the use nuts and bolt cooperates, can carry out spacing to nylon jacket, prevent its play in column pin hole, can regulate the gap simultaneously, make it can adapt to the coupling of production scene complex working condition and different pressures machine.
Between the flange of described screw rod and first nylon jacket and be respectively equipped with the dish spring between the described nut and second nylon jacket, can utilize the distortion energy-absorbing effect of dish spring, the kinetic energy that further reduces the pin play and tremble and bring.
Between described nut and dish spring, be provided with baffle plate, can increase connection stability between dish spring and the coupling.
Between described nut and coupling baffle plate, be provided with locking nut, prevent that nut from because of the vibrations slippage, improving the fastness that connects.
The utility model has the advantages that: elastic component is divided into two, and the shearing force of pin is no longer born by elastic component, but is born by metal screw, has improved the shear resistance of pin greatly, and impact resistance is good, has prolonged the working life of pin, and play is little, and wearing and tearing alleviate.
