Description

A kind of nylon pin coupler applied to slurry agitator

Technical field

The utility model relates to shaft coupling technical fields, more particularly to a kind of nylon applied to slurry agitator Pin coupler.

Background technique

In slurry agitator, shaft coupling is typically used for realize axial force transmission, shaft coupling is for coupling different machines Two axis in structure, allow driven shaft to transmit the device of torque with spindle rotation.General shaft coupling is between pure metal Transmission cooperation, and pin coupler mostly be positive coupling, it is more in particular by the flexible coupling of nylon pin, it is existing Nylon pin coupler be all made of substantially outer ring, inner ring and retaining ring, due to not assembling elastic element, to various relative displacements Uncompensated ability, and shock resistance is poor, and in slurry agitator, work torque easily causes nylon pin unstable when larger And frequently fracture, also cause the damage of pin coupler.When existing shaft coupling works in slurry agitator, it is also easy to produce altogether Vibration, noise is larger and shaft coupling easy to damage, and the pin in pin coupler axis is in shearing and squeezed state at work, inside Stress is concentrated larger at circle, outer ring and pin interface, so be easily damaged.Entire shaft coupling is all by the both ends of nylon pin Skull is lived, therefore can not observe and check the operation conditions and damaged condition of nylon pin at all from outside, is easily occurred because of nylon The phenomenon that pin wears, shreds and shaft coupling is caused to fail, directly affects the normal operation of entire transmission system.

Utility model content

The purpose of this utility model is that: in order to solve in existing slurry agitator nylon pin coupler to various opposite It is displaced uncompensated ability and the poor technical problem of the anti-extrusion ability of anti-vibration, the utility model, which provides, a kind of is applied to mud The nylon pin coupler of blender.

The utility model specifically uses following technical scheme to achieve the goals above:

A kind of nylon pin coupler applied to slurry agitator, including outer ring half a coupler and with outer ring half a coupler The inner ring half a coupler of cooperation, outer ring half a coupler and inner ring half a coupler are formed with shear surface after engagement, on shear surface Ten inclined via-holes for passing through outer ring half a coupler and inner ring half a coupler, all inclined via-holes are uniformly opened by circumferencial direction Center line can be met at shaft coupling axis a little and this point is located on inner ring half a coupler access shaft end direction, Mei Geqing Oblique through hole center line and shaft coupling axis are in 5 °~10 °, are fixed with a nylon pin in each inclined via-hole.

Further, nylon pin inside is hollow, and passing through inside nylon pin has high-strength bolt.

Further, high-strength bolt includes bolt head, and bolt head is located in inclined via-hole under inner ring half a coupler The tightening latch part inside nylon pin is fixed at surface, on bolt head, bolt stem point includes four connect with bolt head The threaded portion of the long polished rod of/tri- bars and a quarter bar length connecting with polished rod, threaded portion, which is fixed with to be located to tilt, to be led to Hex nut in hole at outer ring half a coupler upper surface, is fixed with spring washer between hex nut and nylon pin.

Further, opening of the inclined via-hole on shear surface is equipped with chamfering.

Further, retaining ring is provided on inner ring half a coupler lower surface, retaining ring upper surface contacts half shaft coupling of inner ring simultaneously Device and outer ring half a coupler and being threaded is fixed on the half a coupler of outer ring.

Further, thread connection is the connection of easy-to-dismount studs, retaining ring and inside and outside circle half a coupler contact surface On be provided with elastic washer.

The beneficial effects of the utility model are as follows:

1, the utility model structure novel, it is larger due to vibrating in slurry agitator work, working shaft can be made to generate axis To displacement and radial displacement, axial tension and radial shear power can be decomposed buffering by the nylon pin being obliquely installed, and press axis Since inclined direction is opposite, can also offset each other the symmetrically arranged nylon pin in direction external force suffered by a part, be not susceptible to It fractures, and good to neutrality, and retaining ring further limits the axial displacement of Internal and external cycle shaft coupling, and pin connection is allowed more may be used It leans on, antivibration kinetic force is more preferable, can transmit more high-torque, nylon pin frequently fractures will not occur substantially.

2, the nylon pin inside of the utility model is hollow, increases resistance to fracture, and be internally provided with high-strength Bolt is spent, more high-torque can be transmitted.

3, the chamfering on the shear surface of the utility model effectively reduces stress concentration, and the fatigue for increasing nylon pin is strong Degree, to increase shear resistance.

4, the nylon pin of the utility model is not blocked by retaining ring, user can from external observation to and grasp pin mill The situation of damage early arranges maintenance, plays monitoring effect, reduce the waste in human and material resources and working hour, and more safety can It leans on.
