Abstract
The invention discloses a horizontal refrigerating compressor capable of realizing automatic lubrication. The compressor comprises a compressor body; a rotor rotating shaft of the compressor body is a hollow eccentric shaft; a spiral oil applying sheet is arranged in a hollow inner cavity inside the rotor rotating shaft; one end surface of the spiral oil applying sheet and the rotor rotating shaft are connected with a bearing; the spiral oil applying sheet rotates with the rotor rotating shaft; the spiral oil applying sheet is cylindrical; an oil guiding groove is formed in the cylindrical surface of the spiral oil applying sheet, is a spiral concave arc surface and extends to two end surfaces of the spiral oil applying sheet; an oil storage cavity is formed in a supporting plate and is connected with an oil sucking pipe; one end surface of the spiral oil applying sheet is connected with the oil storage cavity; and lubricating oil is conveyed from the oil storage cavity to to-be-lubricated parts of moving pieces such as a crankshaft, the bearing, a connecting rod, a piston and the like of the compressor by the aid of the oil guiding groove through rotation of the spiral oil applying sheet. With the compressor, the lubricating oil is conveyed to corresponding to-be-lubricated parts of the moving pieces inside the compressor by ingeniously utilizing the space of the inner cavity of the rotor rotating shaft and power.
Description
Technical field
The present invention relates to horizontal technical field of refrigeration compressors, particularly to a kind of self-lubricated horizontal refrigerant compression
Machine.
Background technology
Compressor is the complex machines run up, it is ensured that filling of the movement parts such as compressor crank shaft, bearing, connecting rod, piston
Cunning of sharing in the benefit is the basic demand maintaining machine to run well.To this end, Compressor Manufacturing business often requires to use to specify trade mark lubricating oil,
And require to make regular check on lubricant level and color.But, due to refrigerant system design, construct and carelessness in terms of maintenance, pressure
Contracting machine oil starvation, oil cokeization are rotten, return liquid dilution, cold-producing medium washes away, use lubricating oil inferior etc. to cause movement parts lack of lubrication
Situation is relatively common.Lack of lubrication can cause bearing galling or scuffing, can cause time serious seize, piston be stuck in cylinder with
And cause therefrom connecting rod bending, fracture accident；
Existing refrigeration compressor has and vertical or horizontal is respectively arranged with feature, the most horizontal feature is described below, in order to allow
Refrigeration space is bigger, and a lot of refrigeration plants select small size, it is possible to can work at narrow space, horizontal compressor is exactly it
In a kind of mode because vertical compressor height is higher, and horizontal compressor can make in the installing space of limited height
With.Although saving installing space, but some problems of operationally lubricating system deposited by horizontal compressor, as follows:
Lubricating system refers to be delivered on each position needing lubrication by oil pump at internal lubricating oil；The manufacture of oil pump and installation
Require the highest, so horizontal refrigeration compressor is all difficult to spread and use in entirety manufacture and cost, comprehensively with
Upper technical problem, develops a low cost and easily manufactured horizontal compressor seems particularly important.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of self-lubricated horizontal refrigeration compressor.
In order to solve above-mentioned technical problem, the technical scheme is that
A kind of self-lubricated horizontal refrigeration compressor, including compressor body, the rotor shaft of compressor body is empty
The eccentric shaft of the heart, the hollow lumen within described rotor shaft is provided with oil sheet in spiral type, and spiral type oils the same rotor of sheet end face
Rotating shaft together connects the inner ring of bearing, and the outer ring of bearing is embedded in gripper shoe, and in spiral type, oil sheet rotates with rotor shaft；Institute
Stating oil sheet in spiral type is bar shape, and its damaged surface is provided with oil guide groove, and oil guide groove is spiral helicine depression cambered surface, and oil guide groove is prolonged
Extend oil sheet both ends of the surface in spiral type；
Described gripper shoe is provided with shoe cream room, and shoe cream room connects fuel sucking pipe；In described spiral type, the end face of oil sheet connects
Shoe cream room；By the rotation of oil sheet in spiral type make lubricating oil by oil guide groove from shoe cream room be delivered to compressor crank shaft, bearing,
The movement parts such as connecting rod, piston etc. needs lubricant housings.
Relative to prior art, the invention have the benefit that
The self-lubricated horizontal refrigeration compressor of one of the present invention, by the oil guide groove in oil sheet in spiral type, will profit
Lubricating oil is delivered to opposite side from the side of rotor shaft, and then overflow is to movement parts such as compressor crank shaft, bearing, connecting rod, pistons,
Complete lubrication；In it make use of the intracavity space of rotor shaft, with power, lubrication is delivered to compressor cleverly, each movement parts needs
The corresponding site of lubrication.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of self-lubricated horizontal refrigeration compressor of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.At this it should be noted that for
The explanation of these embodiments is adapted to assist in and understands the present invention, but is not intended that the restriction to invention.Additionally, it is disclosed below
Just can be mutually combined as long as technical characteristic involved in each embodiment of the present invention does not constitutes conflict each other.
As it is shown in figure 1, a kind of self-lubricated horizontal refrigeration compressor, including compressor body 1, compressor body 1
Rotor shaft 2 is hollow eccentric shaft, and the hollow lumen 3 within described rotor shaft 2 is provided with oil sheet 4 in spiral type, spiral type
Upper oil sheet 4 end face together connects the inner ring of bearing 5 with rotor shaft 2, and the outer ring of bearing 5 is embedded in gripper shoe 6, gripper shoe 6
Being connected and fixed on frame inner chamber, in spiral type, oil sheet 4 rotates with rotor shaft 2；In described spiral type, oil sheet 4 is bar shape, its
In screw thread shape, the damaged surface of oil sheet 4 is provided with oil guide groove 41, and oil guide groove 41 is spiral helicine depression cambered surface；
Described gripper shoe 6 is provided with shoe cream room 61, and shoe cream room 61 connects fuel sucking pipe 7；One end of oil sheet 4 in described spiral type
Face connects shoe cream room 61；Make lubricating oil pass through oil guide groove 41 by the rotation of oil sheet in spiral type 4 and be delivered to pressure from shoe cream room 61
Lubricant housings needed for the movement parts such as contracting machine crankshaft, bearing, connecting rod, piston.
