Description
Technical Field
The utility model belongs to the technical field of a refrigeration and air conditioner class technique and specifically relates to a compressor's slotted drive.
Background
The compressor in the refrigeration equipment is characterized in that flowing pressure is provided by refrigerant circulation, gaseous refrigerant is sucked from an air inlet hole of a suction chamber I and then is pressurized by an impeller rotating on the inner circumference and then is directly output, the piston type refrigeration compressor is a type, common piston transmission is that a crankshaft drives a connecting rod to move in a reducing mode, a pull rod in the reducing mode drives a piston connected with the other end of the connecting rod to reciprocate, and the suction pressure power row does work.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide a compressor's slotted guide drive arrangement, the drive sloping cam plate is installed on the main shaft, and drive sloping cam plate and main shaft form the contained angle, the annular crawler shoe is respectively installed to the both ends face that the drive sloping cam plate closed on outer circumferential position, equipartition ball in the recess in the crawler shoe outside, ball ectosphere in two crawler shoes supports with the recess both sides wall contact of piston respectively, the contained angle of drive sloping cam plate and main shaft is decided according to compressor's variety, contained angle increase or reduce, the reciprocal formation of piston also increases in step or reduces, the utility model discloses cancelled the drive mechanism of connecting rod formula, utilize the axial change of drive sloping cam plate terminal surface when rotatory to drive the piston when reciprocal, the drive is direct and rigidity enough, and the fault rate is low, and drive output loss is low.
In order to achieve the above purpose, the technical scheme of the utility model is that: the sliding groove type driving device of the refrigeration compressor comprises a driving swash plate, wherein the driving swash plate is installed on a main shaft, an included angle is formed between the driving swash plate and the main shaft, two end faces, close to the outer circumferential position, of the driving swash plate are respectively provided with an annular sliding shoe, balls are uniformly distributed in a groove on the outer side of each sliding shoe, and the outer spherical surfaces of the balls in the two sliding shoes are respectively contacted and abutted with two side walls of the groove of a piston.
Further, the included angle between the driving swash plate and the main shaft is increased, and the reciprocating formation of the pistons is synchronously increased.
