Description

Dead point mechanism crossed by a kind of spherical compressor gear

Technical field

This utility model patent relates to a kind of spherical compressor gear and crosses dead point mechanism.

Background technology

Spherical compressor is entirely different with existing compressor arrangement and principle, be by main shaft rotarily drive be arranged on spherical in Piston and rotating disk in chamber produce relative motion, in the operating room that space formation a pair or multipair volume are continually changing to produce pressure Contracting and expand, its advantage be without intake/exhaust valve, movement parts is few, it is little to vibrate, mechanical efficiency is high, sealing is reliable, spherical pressure Contracting machine is the invention of great significance on compressor arrangement in recent years, and the applied research of current spherical compressor technology achieves much to enter Exhibition, the most also achieves many patents, and the various dynamic power machines based on spherical compressor are being carried out among industrialization.

Due to the rotation of piston be by eccentric main axis provide power, when main shaft rotate to rotating disk axis overlap with piston axis time, The axis with piston and rotating disk of making a concerted effort that main shaft acts on rotating disk intersects vertically, and making rotating disk is zero around the moment of torsion that piston axis rotates, Piston cannot be made to rotate, thus cause mechanism's clamping stagnation, this is the movement dead of mechanism.Force analysis is: main shaft driving at motor Dynamic lower rotation, main shaft acts on one driving force of rotating disk, and this driving force has a component to make piston rotate about the axis thereof, and drives position Rotating disk bearing pin in the eccentric inclined hole of main shaft rotates, when the axis of the axis and piston rotating to rotating disk is close near overlapping positions, The moment of torsion that this component making piston rotate produces is more and more less until being zero, so in the close coincidence of piston axis and rotating disk axis Front and back, it is rotatable around its axis that piston can not obtain enough moments of torsion, thus occurs rotating catching phenomenon near this position, produces The movement dead of mechanism；When movement dead is initial state or stops operating in this state, then cannot start next time.For knot Structure size is little, under the operating mode of insufficient lubrication, high pressure ratio, the catching phenomenon that spherical compressor causes due to mechanism kinematic dead point is more Substantially.

Summary of the invention

The purpose of this utility model designs a kind of spherical compressor gear exactly and crosses dead point mechanism, makes rotating disk turn to rotating disk axis During with piston axis overlapping positions Shi Ji mechanism dead-centre position, it is possible to produce and make rotating disk continue around the power that own axes rotates, make to turn Son continues rotate and cross dead point.

The technical solution of the utility model is, dead point mechanism crossed by a kind of spherical compressor gear, it is characterized in that: at the rotating disk of rotating disk The lower end of sphere forms a re-entrant cavity, and turntable shaft is sunken in re-entrant cavity, and the upper end of main shaft is placed in described re-entrant cavity, main The eccentric inclined hole of axle matches with turntable shaft, and turntable shaft inserts in the eccentric pivot hole of main shaft upper end, rotating to rotating disk by main shaft Powered rotation；The lower end of rotating disk re-entrant cavity is provided with conical surface internal gear, is provided with and the conical surface in the upper end of spindle carrier The conical surface outer tooth ring that internal gear is meshed, the pitch circle plane of conical surface outer tooth ring is perpendicular to main-shaft axis, during main axis, Conical surface outer tooth ring is in the position being meshed all the time with conical surface internal gear, and the pitch diameter of conical surface internal gear is conical surface outer tooth ring pitch circle 2 times of diameter, the number of teeth of conical surface internal gear is 2 times of the conical surface outer tooth ring number of teeth；
