Description

Cydariform elastic plug tooth-type coupler

Technical field

The utility model relates to a kind of coupling between centers transmitting torque, specifically a kind of cydariform elastic plug tooth-type coupler.

Background technique

Traditional elastic plug tooth-type coupler is all generally to utilize several cylindrical nylon pins to be placed in the involutory hole between two half-couplings and outer ring inner surface, by cylindrical pin longitudinal shear strength transfer moment of torsion, realizing two half-couplings and connect, there is following defect in this structure:

1, this structure shaft coupling transmission compensation diaxon relative displacement is less, and node inclination angle only has 0.5 °, and transmission accuracy requires high, has increased installation difficulty.

2, this lower grade of structure coupling accuracy of manufacturing, and column pin hole is that drilling technique is made, and working surface is made coarse, does not possess interchangeability, has increased maintenance service difficulty.

3, this lower grade of structure coupling accuracy of manufacturing, and cylindrical pin and column pin hole matching gap are larger, and the operational noise of generation is larger.

4, this structure coupling pin hole is cylindrical hole, and it is more serious that pin channels bit phenomenon, exists and transmits failure phenomenon; And be only applicable to the installation of coaxial line horizontal shafting, can not at right angle setting operation.

Summary of the invention

It is large that the technical problems to be solved in the utility model is to provide a kind of side-play amount, and interchangeability is good, easy for installation, the cydariform elastic plug tooth-type coupler that noise is little.

In order to solve the problems of the technologies described above, cydariform elastic plug tooth-type coupler of the present utility model, comprise two half-couplings and can be enclosed within two overcoats outside half-coupling axial end portion, on separating surface between two half-couplings and overcoat, there is the involutory pin-and-hole of longitudinally arranging along circumference, in pin-and-hole, be installed with pin, pin is set to the drum organization diminishing gradually toward two ends diameter from middle, and the left and right sides of described overcoat has the cover plate being sealed on the end face of overcoat two ends.

The middle part of described overcoat has the circle being wholely set with overcoat and cuts off, and described circular partition can be blocked between two half-coupling axle heads.

The utility model has the advantage of:

1, be set to can the large transmission axial dipole field of compensate for slower from the middle drum organization diminishing gradually toward two ends diameter for pin, and installation difficulty is little, long service life;

The setting of the pin-and-hole 2, coordinating with the pin of drum organization can adopt numerical control machine tool processing, can uniformly exchange, and has strengthened interchangeability; Accuracy of manufacturing is high, has solved the not interchangeable defect of original structure, has improved installation efficiency, has reduced maintenance service difficulty;

3, cydariform nylon elastic pin can with column pin hole precision-fit, solved the problem of transmitting accuracy and noise;

4, the middle part of overcoat has the circle that is wholely set with overcoat and cuts off, make its both can level install, also can at right angle setting operation.

Embodiment

Below in conjunction with the drawings and specific embodiments, cydariform elastic plug tooth-type coupler of the present utility model is described in further detail.

As shown in the figure, cydariform elastic plug tooth-type coupler of the present utility model, comprise two half-couplings 1 and can be enclosed within two overcoats 2 outside half-coupling axial end portion, one of them half-coupling is the input external tooth half-coupling that can be connected with input shaft, another one half-coupling is the output external tooth half-coupling that can connect with output shaft, on separating surface (fitting surface) between two half-couplings 1 and overcoat 2, there is the involutory pin-and-hole of longitudinally arranging along circumference, each pin-and-hole being combined to form is evenly arranged at circumferencial direction, in pin-and-hole, be installed with pin 3, pin 3 is set to the drum organization diminishing gradually toward two ends diameter from middle, said pin 3 is nonmetallic material cydariform spring column pin, be preferably nylon elastic pin, can realize two half-couplings by cydariform spring column pin transmitting torque thus connects, the left and right sides of overcoat 2 has cover plate 4, and cover plate 4 is sealed on the end face of overcoat two ends and is bolted,

Further, the middle part of said overcoat 1 has the circle being wholely set with overcoat and cuts off 5, circular partition 5 can be blocked between two half-coupling axle heads, that is to say that interior gear cover is set to intermediate clapboard form, by intermediate clapboard control the position degree of pin, avoid the transmitting accuracy failure phenomenon that in primary standard, the pin utmost point produces to offset phenomena, both realized the condition of can level installing, also can at right angle setting operation simultaneously.

Pin-and-hole in the utility model can adopt numerical control machine tool to process this coupling pin hole, improve coupling accuracy of manufacturing grade, position degree and the accuracy of manufacturing of pin-and-hole and cydariform spring column pin are guaranteed, realized any interchangeability of same specification product, solved original standard low bring can not exchange with transmittance process in the larger defect of noise; The head of said cydariform elastic plug tooth-type coupler input external tooth half connection and output external tooth half connection coordinates suit with the endoporus that connects overcoat, stretchy nylon pin be shaped as the cydariform diminishing gradually to two ends diameter from centre, the profile of the outer peripheral surface of input and output half syncranium portion on longitudinal section is arc simultaneously, realize by the azimuthal variation of circular arc the radial deflection amount that coupling is installed, complete the angle compensation of coupling, reduce installation difficulty, lowered follow-up maintenance service difficulty.
