Existing compressor generally adopts rotary, mainly comprise electric rotating machine, bent axle, connecting rod,, piston, drivening rod and the air-breathing exhaust of piston to-and-fro motion in cylinder reach the purpose that improves air pressure when motor rotates.Shortcomings such as this compressor surface friction drag is big, efficient is low, complex structure, cost height.
How to design a kind ofly have that cost is low, efficient is high, compact structure, compressor in light weight, advantages of wide application range become present problem demanding prompt solution.
Summary of the invention
The purpose of the utility model is the problem that exists to existing technology, and a kind of pair of mover linear compressor that provides, its cost is low, efficient is high, compact structure.
The utility model is realized through following technological scheme:
A kind of pair of mover linear compressor comprises casing, cylinder, piston, stator iron core, winding coil, mover, permanent magnet, end cap, linear bearing, resonant spring, suction valve, outlet valve, adjusting nut, and wherein casing is cylindric; Both sides are provided with end cap; Be followed successively by casing, winding coil, stator iron core, mover, piston shaft from outside to inside, said end cap is provided with linear bearing, and inwall is provided with positioning step; The inside and outside wall end is provided with resonant spring; End cap is connected with the casing end through screw, and the opposite side end cap is provided with positioning step and suction valve outlet valve, also is to be connected with the end through screw.
Wherein said stator iron core is a dumbbell shaped, is formed by the axial radiation closed assembly of silicon steel plate, and stator iron core outer wall recess forms concentrated winding by circumferencial direction winding group coil, and stator iron core outer wall lug boss is fixedly connected with casing inner wall.
Said mover is arranged on the stator two ends, and inner end is provided with annular groove, the bonding annular permanent-magnet body of inlaying in the groove, and the bonding suit tubular of inboard outer wall permanent magnet, piston shaft pass stator inner hole and are fixedly connected with the mover endoporus at two ends; Said piston and piston shaft are made as one, and piston and cylinder are slidingly connected, and hollow shaft and end cap linear bearing endoporus are slidingly connected, and two mover inner side end permanent magnets are identical with inboard outer wall permanent magnet polarity.
The inboard permanent magnet outer wall of said mover, all gapped with stator inner wall, the permanent magnet of two movers reply stator end and inwall is identical polar, and said mover is the strong point through piston shaft with cylinder and linear bearing, straight reciprocating motion.Said piston shaft passes the inboard spring of end cap and is connected with adjusting nut with outside spring with the linear bearing endoporus, regulates the stroke of mover through adjusting nut.
The advantage and the good effect of the utility model are:
1. the two mover linear compressors of the utility model have two movers to be arranged on the stator two ends, and mover inner end permanent magnet is identical with inboard outer wall permanent magnet polarity.When winding coil feeding alternating current, stator field can be thought effect with rotor permanent magnet magnetic field, simultaneously the two ends mover is produced suction and thrust.Promoting mover does straight reciprocating motion vertically and has effectively increased stator the active area of mover has been improved efficient, applied range.
2. the two mover linear compressors of the utility model are simple in structure, compact, cost is low, in light weight, processing and fabricating convenience.
Description of drawings
Accompanying drawing 1 is that the two mover linear compressors of the utility model are to sectional drawing.
Concrete mode of execution
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing 1; A kind of pair of mover linear compressor implemented row; Mainly comprise end cap 4, cylinder 5, piston 6, casing 7, mover 8, mover 15, permanent magnet 9,10,13,14, stator iron core 11, winding coil 12, said end cap 4 is connected with casing 7 ends through screw 3.End cap 4 is provided with Aspirating valves 1, outlet valve 2, stator iron core 11; The outer wall recess is pressed circumferencial direction and is twined winding coil 12, and stator iron core 11 bumps are fixedly connected with casing 7 inwalls, and mover 8 is provided with annular groove with mover 15 inner ends; Permanent magnet 9, permanent magnet 14 bonding being embedded in annular recessed being pickled with grains or in wine.Mover 8, mover 15 inboard outer walls are provided with step, permanent magnet 10, permanent magnet 13 is bonding to be sleeved on inboard outer wall and to be fixedly connected.Piston shaft 6 penetrates mover 8, and mover 15 hole internal fixation connect, and piston shaft 6 penetrates spring 16, linear axis 17, and spring 20 is connected with adjusting nut 21, and end cap 18 is connected with casing 7 ends through screw 19.Mover 8, mover 15, inboard permanent magnet 10, permanent magnet 13, outer wall and stator iron core 11, endoporus is all gapped.
