Description

Spherical compressor

Technical field

This utility model patent relates to a kind of spherical compressor.

Background technology

Spherical compressor is the variable displacement type mechanism of the most neoteric a kind of brand new, and its advantage is without intake/exhaust valve, motion Part is few, it is little to vibrate, mechanical efficiency is high, sealing is reliable, and spherical compressor has obtained constantly in application in recent years is researched and developed Development and perfect, and achieves multinomial patent, if the patent No. is that 03114505.1 (patent name is " a kind of for compressor Variable displacement type mechanism "), 200610104569.8 (patent name is " spherical compressor that can realize multi-stage compression "), The Chinese patent of 201010264211.8 (patent name is " a kind of hinged closure compensation mechanism for spherical compressor ")； Spherical compressor can be widely applied to various field such as gas compressor, refrigerator and refrigeration air conditioner compressor, pump machines etc., with ball Various dynamic power machines based on shape compressor are being carried out among industrialization.

Owing to the rotation of existing spherical compressor piston is to provide power, when main shaft rotates to rotating disk axis and work by eccentric main axis During plug dead in line, the axis with piston and rotating disk of making a concerted effort that main shaft acts on rotating disk intersects vertically, and makes piston around piston axis The moment of torsion rotated is zero, it is impossible to making piston rotate, thus cause mechanism's clamping stagnation, this is the movement dead of mechanism.The patent No. is 201410100390.X, patent name be the Chinese patent of " a kind of the anti-jamming mechanism of spherical compressor rotor " be exactly for solving ball The stuck problem in shape compressor dead-centre position and invent, specifically on turntable shaft increase key seat, key seat is provided with fairlead, Arranging spill slideway on cylinder block sphere or cylinder body lower peripheral surface, spill slideway is distributed in rotating disk rotation process fairlead in institute On corresponding cylinder block sphere or the sliding trace of cylinder body lower peripheral surface；When the moment that moment of torsion is zero of rotating disk rotation, main shaft drives During rotating disk, the contact force that fairlead and spill slideway produce still can make rotating disk continue to keep motion, so that rotating disk is difficult to clamping stagnation, Fundamentally solve the dead unit problem of spherical compressor mechanism kinematic, but, spill slideway needs high accuracy guarantee to guide Overlap coordinate good with spill slideway, and needing during anti-jamming mechanism kinematic, cooling body is set and prevents fairlead and spill Slideway friction produces heating, adds manufacture and operating cost.
