Abstract

The utility model provides a compressor base bearing, it is main includes a tubulose bearing body that uses the high quality carbon structural steel board to make as the base member, the base member above the sintering have a spherical bronze bisque, still apply on this sphere bronze bisque and roll and plastics operational layer that the sintering one deck is given first place to with polytetrafluoroethylene to form a three -layer composite material, the three -layer composite material make an inner wall layer for the tubulose bearing body plastics operational layer, that have pipe wall axial opening seam through roll system technology, base member and the combination of spherical bronze bisque personally submit the molten condition, the thickness of spherical bronze bisque at 0.20mm-0.35mm, the thickness of three -layer composite material is at 1.0mm-2.5mm within range, the suppression has three ring at least slice shapes along the axial equipartition radially to enclose the recess on the internal face of unleaded plastics operational layer, it has good friction and wear performance, and combined material has fine associativity ability.

Description

A kind of refrigerant compression main bearing

Technical field

The utility model relates to a kind of refrigerant compression main bearing, belongs to self oiling bearing technical field.

Background technique

Various chiller plant, little of refrigerator, refrigerator-freezer, the large freezer to different scales, modern skating venue all be unable to do without refrigeration compressor.Traditional refrigeration compressor bearing capacity is larger, if safeguarded proper (oiling agent of regularly annotating), working life still can; If but long-term high load operation, safeguard not in time, progressively will cause the wearing and tearing of main bearing, until scrap, refrigerator can not work, and machine of must tearing open is repaired.So the main bearing in refrigeration compressor is the crucial auxiliary equipment of entire machine.

Although the flourishing state such as the U.S., Germany, Japan of industry recent years has taken the lead in applying a kind of self oiling bearing on refrigeration compressor, has abandoned the roller bearing of tradition as refrigerant compression main bearing; But China's technology in this respect or blank out.

Summary of the invention

The purpose of this utility model is the deficiency overcoming prior art existence, and provides one to integrate with international advanced technology, can realize selflubricating, wear-resistant, life-span length, non-maintaining refrigerant compression main bearing.

The purpose of this utility model has been come by following technical solution: a kind of refrigerant compression main bearing, it mainly comprises one with quality carbon structural steel is the tubulose bearing support that matrix is made, described substrates sintering has spherical bronze bisque, this spherical bronze bisque also applies and rolls and sinter the plastic working layer of one deck based on teflon, and form a kind of 3-layer composite material; Described 3-layer composite material makes tubulose bearing support that an inner wall layer is plastic working layer, that stitch with tube wall axially open by rolling technology.

As preferably: the junction plane of described matrix and spherical bronze bisque is molten state, and the thickness of described spherical bronze bisque is at 0.20mm ~ 0.35mm; The thickness of described 3-layer composite material is within the scope of 1.0mm ~ 2.5mm; The internal face of described unleaded plastic working layer is suppressed with the slice shape radial direction circle groove that at least three circles are uniform vertically.

Product described in the utility model has excellent friction and wear behavior, tests under dry conditions, and load reaches 8N/mm ². during linear velocity 0.2m/s, friction factor≤0.2, wear extent≤0.02mm, composite material has good binding ability, sample clamps by special testing apparatus, do positive and negative 60 ° to bend five times, delamination and phenomenon of rupture must not be had, for refrigeration compressor industry provides the New Refrigerating main bearing of compressor of this technological performance.

Embodiment

Be described in detail the utility model is novel below in conjunction with accompanying drawing: shown in Fig. 1,2,3, a kind of refrigerant compression main bearing of the utility model, it mainly comprises one with quality carbon structural steel is the tubulose bearing support that matrix 1 is made, it is characterized in that above described matrix 1, sintering has spherical bronze bisque 2, this spherical bronze bisque 2 also applies and rolls and sinter the plastic working layer 3 of one deck based on teflon, and form a kind of 3-layer composite material; Described 3-layer composite material makes tubulose bearing support that an inner wall layer is plastic working layer 3, that stitch with tube wall axially open by rolling technology, because rolling technology is existing known technology, is no longer described.

Shown in figure, the junction plane of described matrix 1 and spherical bronze bisque 2 is molten state, and the thickness of described spherical bronze bisque 2 is at 0.20mm ~ 0.35mm; The thickness of described 3-layer composite material is within the scope of 1.0mm ~ 2.5mm; The internal face of described unleaded plastic working layer 3 is suppressed with the slice shape radial direction circle groove that at least three circles are uniform vertically.
