Abstract
The utility model relates to an over-loading protection device used in the high-speed rotating equipment. The device comprises a power output axis, a power input axis, a moment transmission bolt, an upper safe clutch seat and a lower safe clutch seat, as well as a taper locating seat and a rolling bearing. The upper safe clutch seat and the lower safe clutch seat are installed oppositely and are connected with several moment transmission bolts. A rolling bearing is equipped inside the lower safe clutch seat, while the taper locating seat is installed in the rolling bearing. The lower end of the power output axis is set to be in the taper shape and is installed into the taper locating seat. A transmission chain can be safely disconnected. Moreover, the equipment can continue rotating steadily under the high-speed rotation state, so resonance would be effectively avoided, important parts would be further protected and phenomena of friction and knocking as a result of disconnection of the moment transmission bolts would be prevented. The protection device is provided with the simple, safe and reliable structure, low manufacture cost, good rigidity and high coaxial degree, so it can be used in the high-speed rotating equipment (equal to or more than 3000r/min).

Background technique
In the prior art, overload protection arrangement not only can be realized the transmission of power, can also in particular cases disconnect Transmitted chains transship, stuck etc., and vitals is protected.General overload protection arrangement comprises the shear pin formula at present; castellated; ball type and friction type etc. are several; but existing overload protection arrangement; equipment for high speed rotating; when carrying out overload protection; both relative speed differences are very big; under the inertial centrifugal force loading, will produce the concentrated and distortion of very big stress; high vibration phenomenon and friction phenomenon appear; and produce a large amount of heats; cause the damage of equipment unit; therefore require the safety protection device of design when protecting; rotary inertia; deformation and amount of unbalance must be very little; and have high stability, destroy little characteristics, and present overload protection arrangement can not satisfy above-mentioned requirements fully more than 20000r/min.
Summary of the invention
The purpose of this utility model is to provide the overload protection arrangement that is fit to the high-speed rotating equipment use; pass through the technical program; it can effectively in particular cases disconnect Transmitted chains transship, stuck etc.; and can effectively prevent under height revolves speed; the stress that the inertial centrifugal force loading often occurs is down concentrated and distortion is produced high vibration phenomenon and friction phenomenon are to remedy the deficiencies in the prior art.
The technical scheme in the invention for solving the above technical problem is: the overload protection arrangement that a kind of suitable high-speed rotating equipment uses; it comprises pto; power input shaft; the transmission of torque screw; last safety clutch seat and following safety clutch seat; described pto is provided with spline; last safety clutch seat links to each other with pto through spline engagement; following safety clutch seat links to each other with power input shaft; it also includes cone type positioning seat and rolling bearing; the described safety clutch seat of going up is oppositely arranged with following safety clutch seat; and be connected by several transmission of torque screws; be provided with rolling bearing in the safety clutch seat under described; the cone type positioning seat is arranged in the rolling bearing; the lower end of described pto is arranged to tapered, and plug-in mounting also is pressed in the cone type positioning seat.Described going up between safety clutch and the cone type positioning seat also successively to being arranged with sealing seat and adjustment pad was pressed on above the sealing seat on safety clutch following, and adjusting strip is pressed on the upper-end surface of cone type positioning seat.
Be set with butterfly spring on the described transmission of torque screw, the transmission of torque screw passes down safety clutch seat spinning from bottom to top on last safety clutch, and the position that described transmission of torque screw is gone up between safety clutch seat and the following safety clutch seat is provided with limit power ring shaped slot.
The utility model is when using, in the utilization, transmission of torque screw between following safety clutch is realized transmission of power, the limit power ring shaped slot that transmission of torque screw neutral position is provided with, has stress concentration effect, cut off at this strength weak place during overload, disconnect transmission system, the transmission of torque screw adopts inverted structure, and butterfly spring has been installed on screw head top, when the transmission of torque screw is cut off, under gravity and the acting in conjunction of butterfly spring elastic force, the screw shearing plane is separated rapidly, prevent that the collision influence that shearing plane takes place from damaging remaining part, because high-speed rotating equipment rotating speed height, the cone type positioning seat passes through roller bearings, make when disconnecting the transmission of torque screw, when last safety clutch seat and following safety clutch seat are thrown off, continue the rotation that is keeping more stable.
The overload protection arrangement medium power output shaft that suitable high-speed rotating equipment in the utility model uses is connected by spline with last clutch base; no matter be when clutch base links to each other by the transmission of torque screw with following clutch base on two; still overload; the stuck grade when transmission of torque screw disconnects under the non-normal working condition; can make the tapered axle head in pto lower end; all the time be pressed in the cone type positioning seat; keep its due rigidity and coaxality; when last safety clutch seat and the disengagement of following safety clutch seat; make the rotation that pto under the high speed rotating still can be more stable under the situation of falling off, stop up to rotation.Later can also make mechanism recover normal function by changing the transmission of torque screw.
The beneficial effect of the overload protection arrangement that the suitable high-speed rotating equipment that the utility model relates to uses is: owing to adopted the technical program; overloading; the stuck grade under the non-normal working condition; can realize the disconnection of Transmitted chains safely; and under this high speed rotating state; can realize continuing smooth rotation; avoid resonance to take place effectively; vitals is further protected; and after further having stopped the disconnection of transmission of torque screw; the friction and the impingement phenomenon that occur; its structure tube list; safe and reliable, low cost of manufacture can be used in the rotating equipment of the above higher rotation speed of 30000r/min.
