Technical Field

The invention relates to the field of compressors, in particular to a compression cylinder assembly, a rotary cylinder piston compressor and heat exchange equipment.

Background

The existing rotary cylinder piston compressor comprises a rotating shaft, a piston sleeved outside the rotating shaft, an air cylinder sleeved outside the piston and a cylinder sleeve sleeved outside the air cylinder, wherein the rotating shaft rotates around a fixed axis, the air cylinder rotates around another fixed axis under the limitation of the cylinder sleeve, the rotating shaft and the rotating axis of the air cylinder are arranged in parallel and at intervals, the rotary cylinder piston compressor is essentially a rotary cylinder piston compressor obtained by combining the main structure of the piston rotary cylinder piston compressor and the main structure of a rotor type rotary cylinder piston compressor by adopting the structure principle of a cross slide block, and the structure principle of the rotary cylinder piston compressor can refer to the Chinese patent application with the publication number of CN 109595157A.

In the above-mentioned rotary cylinder piston compressor, there are two main ways of supporting the cylinder in the prior art, one is to support the inner circle of the cylinder through a matching structure such as a flange, and the other is to support the outer circle of the short shaft of the cylinder through a matching structure such as a limiting plate. Specifically, can be according to concrete demand and nimble collocation, for example can both ends of cylinder all be interior circle supporting, or cylinder both ends all be the excircle supporting, or cylinder one end interior circle supporting, the other end excircle supporting, interior circle supporting can refer to the interior circle cooperation structure that CN109595157A recorded, and excircle supporting can refer to the excircle cooperation structure that CN109595157A recorded.

In excircle cooperation structure, the protruding axle of cylinder wears to locate in the mounting hole of limiting plate, and the protruding axle support is on the pore wall of mounting hole, however, because the reason of gas pressure size and direction change among the rotary cylinder piston compressor leads to having great pressure between cylinder and the limiting plate, leads to having great impact and wearing and tearing between protruding axle and the limiting plate easily, leads to the structural damage of protruding axle and limiting plate easily.

Disclosure of Invention

One of the objects of the present invention is to provide a compression cylinder assembly of a rotary cylinder piston compressor which facilitates reliable cylinder block support.

In order to achieve the aim, the compression cylinder assembly of the rotary cylinder piston compressor comprises a rotating shaft, a piston, a cylinder sleeve and at least one excircle matching structure; the cylinder is arranged in the cylinder sleeve, the axis of the rotating shaft is along a first direction, a first hole penetrating through the piston is arranged on the piston, a second hole and a third hole penetrating through the cylinder are arranged on the cylinder, the second hole is intersected with the third hole, the piston is slidably arranged in the second hole, the penetrating directions of the first hole and the second hole are along the first direction, and the rotating shaft penetrates through the first hole and the second hole; the excircle matching structure comprises a limiting plate, the limiting plate and a cylinder sleeve are distributed along a first direction, the limiting plate and the cylinder sleeve are fixed, a mounting hole is formed in the limiting plate, an annular convex shaft is arranged at least one end of the cylinder along the first direction, and the convex shaft is rotatably arranged in the mounting hole; and a damping hole which is communicated along the first direction is arranged on the limiting plate and is adjacent to the mounting hole.
