Description
本申请要求于2016年07月29日提交中国专利局、申请号为201610614674.X、发明名称为“一种转缸活塞压缩机泵体及采用其的压缩机”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese Patent Application filed on July 29, 2016, the Chinese Patent Application No. 201610614674.X, the invention titled "a rotary cylinder piston compressor pump body and a compressor using the same" The entire contents of this application are incorporated herein by reference.
本发明涉及压缩机技术领域,尤其涉及一种转缸活塞压缩机泵体及采用其的压缩机。The invention relates to the technical field of compressors, in particular to a pump body of a rotary piston compressor and a compressor using the same.
转缸活塞压缩机属于一种全新结构的制冷活塞压缩机,本质上是采用一种十字滑块结构原理。参照图10,O1为转轴圆心,O2为气缸圆心,e为圆心距(即压缩机的偏心量),方块为活塞质心。转轴转动时,带动活塞进行圆周运动,活塞相对于气缸中心的距离在0~e的范围内运行。转轴与气缸成偏心装配,转轴通过活塞带动气缸旋转。由于转轴和气缸存在偏心关系,运行时转轴和气缸分别绕各自的轴心旋转,相对于气缸,活塞作往复运动,实现气体压缩。The rotary cylinder piston compressor belongs to a new type of refrigeration piston compressor, which essentially adopts a cross slide structure principle. Referring to Fig. 10, O1 is the center of the rotating shaft, O2 is the center of the cylinder, e is the center of the circle (i.e., the amount of eccentricity of the compressor), and the square is the center of mass of the piston. When the rotating shaft rotates, the piston is driven to move in a circular motion, and the distance of the piston with respect to the center of the cylinder is in the range of 0 to e. The rotating shaft is eccentrically assembled with the cylinder, and the rotating shaft drives the cylinder to rotate through the piston. Due to the eccentric relationship between the rotating shaft and the cylinder, the rotating shaft and the cylinder rotate around their respective axes during operation, and the piston reciprocates relative to the cylinder to achieve gas compression.
具体的,转缸活塞压缩机转轴与气缸成偏心装配,转轴通过活塞带动气缸旋转,并通过气缸短轴内的短轴孔向气缸转轴内的转轴孔泵油。由于转轴与气缸存在偏心关系,运行时转轴和气缸分别绕各自的轴心进行旋转,一方面转轴的下端面与气缸端面接触,保证了转轴的供油,却对转轴侧面的油槽油路循环带来不利的影响,不利于重工况下转轴与活塞运动副之间的润滑,另一方面转轴内孔与气缸转轴内孔相交的面积对转轴的供油有较大的影响。Specifically, the rotating shaft of the rotary piston compressor is eccentrically assembled with the cylinder, and the rotating shaft drives the cylinder to rotate through the piston, and pumps the oil through the short shaft hole in the short shaft of the cylinder to the rotating shaft hole in the cylinder rotating shaft. Due to the eccentric relationship between the rotating shaft and the cylinder, the rotating shaft and the cylinder rotate around the respective axes during operation. On the one hand, the lower end surface of the rotating shaft is in contact with the end surface of the cylinder, thereby ensuring the oil supply of the rotating shaft, but the oil groove of the oil groove on the side of the rotating shaft The unfavorable influence is not conducive to the lubrication between the rotating shaft and the piston moving pair under heavy working conditions. On the other hand, the area where the inner hole of the rotating shaft intersects with the inner hole of the cylinder rotating shaft has a great influence on the oil supply of the rotating shaft.
针对上述问题,需要一种能够解决现有技术中存在的转轴侧面的油槽油路循环阻力较大的转缸活塞压缩机泵体及采用其的压缩机。In view of the above problems, there is a need for a rotary piston compressor pump body and a compressor using the same that can solve the problem of the circulation resistance of the oil groove oil passage on the side of the rotating shaft existing in the prior art.
