Description
The utility model belongs to pump and compressor.
Existing common sliding-vane compressor, slide plate is high-speed slide in cylinder body, and fricting loss power is very big, for solving the frictional loss problem of slide plate, has occurred two sliding ring type off-load ring sliding-vane compressors the earliest.(see the Deng Dingguo of Xi'an Communications University chief editor " rotary compressor " 206 pages) but this pair of slip ring off-load ring sliding-vane compressor emphasis solved the life problems of slide plate, the frictional work of off-load ring and cylinder body is still very big, No. 3360192 patents of the U.S. propose a kind of through improved two off-load ring sliding-vane compressors that special rolling bearing supporting is arranged, and greatly reduce the fricting loss power of slide plate.But the off-load ring of this compressor, slide plate, rotor, to unload between body the total leakage area in formed working room bigger, and supporting off-load ring needs four bearings, and structure is comparatively complicated.
The purpose of this utility model provides a kind ofly through improved sliding-vane compressor, and its slide plate frictional loss is little, good seal performance, structure are also simpler.
The utility model is to realize by the relief arrangement that improves known technology.
Important technology feature of the present utility model be its relief arrangement be one by the supporting of two bearings, rotary cylinder-block rotating end cap, that driven by driving mechanism is arranged.
Air compressor of the present utility model is by stationary housing, the fixedly connected left side of stationary housing therewith, right fixedly end cap, the rotor that 2～30 longitudinal flutings are arranged, in each longitudinal fluting of this rotor the slide plate that can radially be free to slide is housed, rotor is fixedlyed connected with rotor shaft or is become one, but the two point supporting is arranged on the rotor shaft, or the two bearings of cantilever support rotor, one end of rotor shaft stretches out fixedly end cap and motor direct connection or becomes one with motor reel, formation is advanced, the inlet hole of venting gas appliance, exhaust port, be arranged on fixed end and cover, and the relief arrangement that is arranged between stationary housing and rotor constitutes.Feature of the present utility model be described relief arrangement be one by the supporting of two bearings, rotary cylinder-block rotating end cap, that driven by driving mechanism is arranged, this rotary cylinder-block is made of with one or two rotating end cap of fixedlying connected with it cylinder block, and one of them rotating end cap can become one with cylinder block, on the cylinder block circumference, or have can bearings mounted axle journal in the outside of rotating end cap.Support the bearing of this rotary cylinder-block, can be also cantilever support of two point supportings, the parallel rotor outside that is sleeved on prejudicially of this rotary cylinder-block, when this rotary cylinder-block has left and right two rotating end caps, on one of them or two rotating end caps circle vent should be arranged, this circle vent should be corresponding with the inlet and outlet hole that fixed end covers.
The homodromal driving mechanism of the rotary cylinder-block of air compressor of the present utility model and rotor has multiple scheme: can be by mutual frictional force driving mechanism; It can also be few tooth difference inside engaged gear driving mechanism; Be that internal gear is fixedlyed connected with rotary cylinder-block, the internal gear driving mechanism that external gear is fixedlyed connected with rotor shaft; It also can be parallel axes coupling driving mechanism; Also can be to have the independent motor drives rotary cylinder-block and the rotor of synchronous speed to rotate in the same way.
Because air compressor of the present utility model has reduced the fricting loss power of slide plate, when compressor pressure was low, the temperature rise of machine was very low, so might adopt under the normal temperature such as MC nylon or nylon 1010 wear-resisting property excellent engineering plastics as the slide plate material.
The utility model is compared with common sliding-vane compressor, and little, the reliability and durability advantage of slide plate fricting loss power is arranged.
