Abstract
The utility model relates to a turn plate rotation synchronizing mechanism for a spherical compressor. A junction surface of a sphere of a turn plate and a spherical inner sphere of a cylinder body is provided with a turn plate rotation synchronizing mechanism composed of an elastic steel ball and a concave slide way; the elastic steel ball is composed of a steel ball and a spring; a counter bore is formed in the inner sphere of the cylinder body; the steel ball is arranged in the counter bore after pressing the spring; the concave slide way is arranged on the sphere of the turn plate, and is distributed in a sliding track of the steel ball on a close sphere during rotation of the turn plate; and the section of the concave slide way is adaptive to the steel ball in shape. The turn plate rotation synchronizing mechanism has the advantages that: when the turn plate rotates to a position at which the axis of the turn plate is overlapped with the axis of a piston, the torque generated by the synchronizing mechanism can still move the turn plate continuously, so that the turn plate can not be easily chucked, and further the problem of dead point in motion of the spherical compressor mechanism can be foundationally solved.
Description
Technical field
The utility model relates to a kind of synchronized movement mechanism, particularly a kind of synchronism mechanism for the rotation of spherical compressor rotating disk.
Background technique
The spherical compressor technology is a brand-new technology invention, its technological core is a kind of variable volume mechanism of space, the patent No. of application in 2003 is that ZL03114505.1, patent name are that the disclosed technological scheme of Chinese patent of " a kind of variable capacity mechanism for compressor " is the basic structure of this technology, can realize single stage compression; The patent No. is that ZL200610104569.8, patent name are that the Chinese patent of " spherical compressor that can realize multistage compression " has been done significant development and breakthrough again to this technology, can realize multistage compression; The patent No. be ZL201010264211.8, patent name for the Chinese patent of " a kind of hinge sealing crack compensation mechanism for spherical compressor " be significant improvement and optimization to spherical compressor basic structure, solved process issues, particularly even more important to the compressor of microstructure.
The advantage of this spherical compressor is: no intake/exhaust valve, movement parts is few, vibration is little, mechanical efficiency is high, the sealing is reliable etc.But its shortcoming is: because the rotation of piston is to provide power by eccentric main axis, when main axis rotation overlaps with piston axis to the rotating disk axis, main shaft acts on the intersect vertical axis with piston of making a concerted effort on the rotating disk, the moment of torsion that rotating disk is rotated around piston axis is zero, can't make the piston rotation, this is the motion of mechanism dead point.Force analysis is: main shaft rotates under the driving of motor, main shaft acts on driving force of rotating disk, this driving force has a component to make piston around its axis rotation, drive is arranged in the rotating disk bearing pin rotation of the eccentric inclined hole of main shaft, when approaching, the axis of the axis that rotates to rotating disk and piston overlaps near the position, this moment of torsion that component of piston rotation is produced is more and more littler of being zero, so approach the coincidence front and back at piston axis and rotating disk axis, piston can not obtain enough moments of torsion and rotate around its axis, thereby catching phenomenon near this position, occurs rotating, produce the motion of mechanism dead point; When the motion dead point is initial state or stops operating at this state, then can't start next time.The patent No. is that ZL200610104569.8, patent name are that the Chinese patent of " spherical compressor that can realize multistage compression " also once arranged permanent-magnet material respectively on main shaft and the contacted rotation surface of cylinder body, at contacted the identical magnetic material of polarity is set, the magnetic pole of identical polar repels mutually when close when turning to this position, utilize the identical repulsive force of polarity to push main shaft open several angle, stop when preventing piston axis and rotating disk dead in line.Though the method prevents from shutting down herein, not from catching up with the stressed problem that solves dial rotation.For physical dimension bigger mechanism and lubricated good, frictional force small construction, when rotating to this position, rotating disk relies on the inertia overcome friction can pass through this position, but the structure less for physical dimension, that lubricating condition is relatively poor, because inertia is less, frictional force is bigger, easy clamping stagnation when turning to this position and stall.
Summary of the invention
The purpose of this utility model is exactly on the basis of Chinese patent ZL201010264211.8, according to main shaft and rotating disk power transmission relationship, when solving piston axis and rotating disk dead in line or approach when overlapping, main shaft can't provide the dynamical problem of piston rotation, thereby thoroughly solve when frictional force is big, hour easy problem of clamping stagnation of the little inertia of compressor arrangement size, make compressor rotate more steadily, along sliding and reliable.
The technical solution of the utility model is, a kind of rotating disk rotating synchro structure for spherical compressor is characterized in that: the spherical inner ball surface of rotating disk sphere and the cylinder body face of being slidingly connected movingly is provided with the rotating disk rotating synchro structure that elastic steel ball and spill slideway constitute; Described elastic steel ball is to be made of steel ball and spring, at rotating disk and cylinder body cylinder body inner ball surface or rotating disk sphere movingly one counterbore is set, and the steel ball pressing spring is placed in the counterbore; At another spherical of being slidingly matched corresponding with steel ball counterbore position the spill slideway is set, this spill slideway is distributed in that steel ball is on the sliding trace on the spherical of fitting in the dial rotation process, and sectional shape and the steel ball of spill slideway adapt;
Described spill slideway can be the full track mark that steel ball slides at corresponding sphere, and can save spring this moment;
Described spill slideway also can be the part track that steel ball slides at corresponding sphere, in the first and last section of spill slideway arc transition is set, and when piston axis and rotating disk dead in line, steel ball is positioned at spill slideway middle part;
Described elastic steel ball is at the rotating disk sphere, and corresponding spill slideway is symmetrically distributed in the cylinder body inner ball surface;
Described elastic steel ball also can be on the cylinder body inner ball surface, and then corresponding spill slideway is symmetrically distributed on the rotating disk sphere;
Described elastic steel ball can be many groups, and multistage spill slideway is set accordingly.
The utility model has the advantages that between rotating disk sphere and the cylinder body inner ball surface that matches rotating disk rotating synchro structure is set, make rotating disk turn to the rotating disk axis when overlapping the position with piston axis, the moment of torsion that rotating disk obtains from main shaft is zero moment, the moment of torsion that lazy-tongs produce still can make rotating disk continue to keep motion, thereby make rotating disk be difficult for clamping stagnation, fundamentally solved the dead unit problem of spherical compressor mechanism kinematic.
