Description
Technical field
The invention belongs to Compressor Technology field, relate to the error transfer factor structure of a kind of screw compressor.
Background technology
Scroll air compressor is high with its efficiency, noise is low, volume is little, it is the most energy-conservation to be conducive to and the advantage such as protection environment and wide
General be applied to industry, agricultural, transportation, the civilian industry such as pneumatic all need compressed-air actuated occasions.Swirled air compresses
Owner's part to be run is whirlpool dish, the only engagement of whirlpool dish, does not produce abrasion, thus the life-span is more longer than piston type, screw compressor,
It it is pneumatic machinery ideal power source.In scroll air compressor, it is divided into Moving plate and quiet dish as the main whirlpool dish running part, dynamic
Set vortex sheet in dish and quiet dish, generally, be bonded to each other formed compression chamber by Moving plate and quiet dish, when Moving plate is driven along one by bent axle
Determining circular path when making translation, Moving plate vortex sheet moves relative to quiet dish vortex sheet, and the compression chamber i.e. formed by both moves also
Change its volume, thus carry out sucking, compress, discharge, complete compressed-air actuated process.
A kind of low compression ratio oil-free vortex air as open in Chinese invention patent application (201510280997.5) compression
Machine assembly, including host shell and orbiter, host shell is by top in the middle part of three secondary eccentric shafts and host shell
Orbiter is connected, and the upper end of orbiter is provided with fixed scroll, and fixed scroll edge is connected with upper end, host shell edge,
Wherein the fit clearance between fixed scroll and orbiter directly affects the sealing of compression chamber, and then affects work efficiency,
Within orbiter connects face tooth top seal groove with fixed scroll, it is provided with self-lubricating pad for this above-mentioned compressor and adjusts soft
Pad, improve sealing by self-lubricating pad and adjustment cushion, but this kind of seal member is easy during long-time use
Ageing failure, and orbiter, fixed scroll, secondary being between eccentric shaft, bearing axially engage installation, easily occurs the most tired
Long-pending error, causes assembly precision poor.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, it is proposed that the error of a kind of screw compressor is adjusted
Whole structure, the error transfer factor structure of this screw compressor makes the assembling of screw compressor convenient, and assembly precision is higher.
The purpose of the present invention can be realized by following technical proposal: the error transfer factor structure of a kind of screw compressor, whirlpool
Rotation compressor includes that the quiet dish of fixed bearing block, vortex, eddy spinner disk and Moving plate bearing block, the quiet dish of described vortex are connected in fixing axle
In bearing, described Moving plate bearing seat is in fixed bearing block, and described eddy spinner disk is fixedly connected with Moving plate bearing block, and vortex moves
Dish dish quiet with vortex matches, it is characterised in that described error transfer factor structure includes positioning bent axle and adjusting pad, described Moving plate
Having dead eye one on bearing block, be provided with bearing one in described dead eye one, described Moving plate bearing block is fixed with can be by axle
Holding a platen one being pressed in dead eye one, one end of described location bent axle is fixedly plugged in bearing one, described fixing axle
Having dead eye two in bearing, be provided with bearing two in described dead eye two, the other end of described location bent axle is fixedly plugged in axle
In holding two, described adjustment pad is arranged between the end face of bearing two and the bottom surface of dead eye two, solid on described fixed bearing block
It is connected with and is pressed on bearing two, and make bearing two be pressed on the platen two adjusted on pad.
The quiet dish of vortex and eddy spinner disk match, and motor is connected with Moving plate bearing block, drive whirlpool by Moving plate bearing block
Rotating disk operates, and therefore the quality of fit between eddy spinner disk and the quiet dish of vortex directly affects work efficiency, for this this scroll compression
Contracting machine passes through error transfer factor structure coordinating between direct dish quiet to eddy spinner disk and vortex in screw compressor assembling process
Gap is adjusted, concrete, and bearing one and bearing two all have two, for pairing bearing, is fixedly mounted by eddy spinner disk in advance
On Moving plate bearing block, platen one and platen two being respectively sleeved at the two ends of location bent axle, it is fixed to be sleeved on by two bearings one
One end of position bent axle, two bearings two are sleeved on the other end of location bent axle, then two bearings one are pressed into Moving plate bearing block
In dead eye one, platen one is fixed on Moving plate bearing block so that platen one compresses bearing one, by Moving plate bearing block, bearing
One, platen one, location bent axle and bearing two are installed and are put in place and eliminate gap error each other, owing to above-mentioned several parts are equal
Being axially mounted, assemble relatively simple, assembly precision is the highest, then measures eddy spinner disk end face between bearing biend
Distance, according to the distance between measurement result and the quiet dish of vortex that is pre-designed to fixed bearing block, it is possible to calculate and work as whirlpool
Distance between rotating disk and vortex quiet dish lean and correct assembly rear bearing biend and dead eye two bottom surface, it is suitable so can to select
The adjustment pad of thickness, puts into dead eye two by this adjustment pad, rotate location bent axle and make bearing two on the bent axle of location with
Dead eye two aligns and is pressed into, and is fixed on fixed bearing block by platen two so that platen two compresses bearing two, and bearing two compresses
Adjust pad, thus realize the installation of Moving plate, in superincumbent installation process, due in advance will on the bent axle of location all parts it
Between gap error that may be present be fully transferred to position bent axle end, i.e. between bearing two and dead eye two bottom surface, then
Corresponding adjustment pad is pre-selected by calculating to assemble so that easier for installation, and install after eddy spinner disk with
Between the quiet dish of vortex to axially engage precision higher.
In the error transfer factor structure of above-mentioned screw compressor, described fixed bearing block offering connecting hole, this is even
Connect hole to parallel with location bent axle, described platen two offers screw, in described connecting hole, is equipped with hold-down bolt, this compression
The end of bolt is screwed onto in the screw of platen two, and the effect pressing disc two at hold-down bolt is pressed on the outer end of bearing two outer ring
On end face, the inner end face of bearing two outer ring is pressed on adjustment pad.The outer end of bearing one is towards dead eye one aperture
One end, the outer end of bearing two is the one end towards dead eye two aperture, and hold-down bolt is used for connecting platen two, and platen two is to bearing
Hole two covers so that bearing two has preferable lubricant environment, the axial phase of the length direction of connecting hole and dead eye two
With, platen two can be strained when therefore screwing hold-down bolt, act on lower bearing two at platen two and be pressed on adjustment pad, it is achieved
Axial restraint to bearing two outer ring, and fully eliminate axial gap error, improve assembly precision.
