Abstract
The utility model discloses a sliding bearing for a pump, which is mainly used for a shield pump, a magnetic pump and other pumps; comprising a sliding shaft lining 2. The utility model is characterizThe utility model discloses a sliding bearing used for a pump, mainly for a canned-motor pump and a magnetic force pump and also for other pumps. The utility model comprises a sliding bearing bushing ed in that the sliding shaft lining 2 is inserted and loaded in a sliding bearing seat 1; a sliding bearing sleeve 3 is matched with the sliding shaft lining; the friction pair can be formed between t2. The utility model is characterized in that the sliding bearing bushing 2 is embedded in a sliding bearing seat 1, and a sliding bearing sleeve 3 is arranged to match the sliding bearing bushing 2, he sliding shaft lining 2 and the sliding bearing sleeve 3; a thrust disc 4 is arranged between the sliding bearing sleeve 3 and the end face of the sliding bearing seat 1. The utility model has the aand a friction pair is formed between the sliding bearing bushing 2 and the sliding bearing sleeve 3, and a pushing disk 4 is arranged between the sliding bearing sleeve 3 and the end face of the sliddvantages that the intensity is high, the abrasion resistance is good, the corrosion can be prevented, the larger axial force can be bore, the service life is long, the frequent replacement of spare ping bearing seat 1. The utility model has the advantages that the strength is high; the wear-resistant capability is better; the corrosion can be resisted and the tenacity is better; a bigger axial foart doesn't need, the user's maintenance charge can be saved, the production cost can be reduced, and the application range is wide. rce can be endured and the service life is long; the frequent spare parts changing can be avoided so as to save the maintenance cost for users; the manufacturing cost can be reduced; the application scope is wide.
Description
Technical field:
The utility model relates to a kind of bearing, is mainly used on canned motorpump and the magnetic drive pump, also can be used for other.
Background technique:
Employed sliding bearing structure is single on canned motorpump and the magnetic drive pump, the overwhelming majority is the form of graphite bushing, be that the graphite bushing outer side surface is set in the cartridge housing, the inner side surface of graphite bushing directly is enclosed within the rotating shaft, form friction pair with rotating shaft, the sliding bearing wear-resisting property of this structure is poor, working life is short, need the frequent spare part of changing, increase user's day-to-day maintenance, wasted many unnecessary manpower and financial resources, and corrosion phenomenon can take place when running into some medium, Applicable scope is limited to some extent.
Summary of the invention:
The purpose of this utility model provides that a kind of friction property is good, the life-span is long, need frequently to change spare part, save the Sliding bearing for pump of maintenance expenses, to overcome the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of Sliding bearing for pump, it comprises slide bushings 2, it is characterized in that: slide bushings 2 inserts are in plain bearing housing 1, is furnished with sliding bearing sleeve 3 mutually with slide bushings 2, form friction pair between slide bushings 2 and the sliding bearing sleeve 3, between the end face of sliding bearing sleeve 3 and plain bearing housing 1, be provided with thrust disc 4.
Described thrust disc 4 is sleeved on the sliding bearing sleeve 3.
The material of described slide bushings 2 is that the material of SIC30, sliding bearing sleeve 3 is that the material of stainless steel spraying LW5, thrust disc 4 is PTFE and graphite mixture.
The utility model compared with prior art has that intensity height, wear-resisting property are good, corrosion-resistant, good toughness, can bear bigger axial force, long service life, needs frequently to change spare part, can be the user and save maintenance cost, reduce cost of production, the extensive advantage of Applicable scope.
Description of drawings:
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment:
As shown in the figure: 1 is plain bearing housing, can select metallic material for use, and as cast steel etc., slide bushings 2 cylindraceous is installed in the plain bearing housing 1, and with pin 5 location.The inner side surface of the outer side surface of sliding bearing sleeve 3 and slide bushings 2 coincide and forms friction pair.Be provided with thrust disc 4 between the edge of one termination of sliding bearing sleeve 3 and the edge, termination of plain bearing housing 1, thrust disc 4 is sleeved on the sliding bearing sleeve 3 in the form of a ring, and thrust disc 4 bears axial force during use.
Described slide bushings 2 materials are SIC30, and the material of sliding bearing sleeve 3 is stainless steel spraying LW5, and the material of thrust disc 4 is the mixture of PTFE and graphite.
During installation sliding bearing sleeve 3 and rotating shaft closely cooperated and get final product.
