Litlhaloso le litekanyo tsa lihlahla tse akaretsang tsa bronze
Lihlahla tsa bronze (kapa lihlahla tsa alloy tsa koporo) li sebelisoa haholo mecheng, lisebelisoa tsa indasteri, likepe, likoloi le masimo a mang. Hangata li sebelisoa ho li-sliding bearings, lihlahla tse nang le lihlahla, mehaho ea tšehetso le libaka tse ling. Litlhaloso le boholo ba lihlahla tsa bronze li fapana ho latela litlhoko tsa kopo, thepa ea thepa, litlhoko tsa mojaro le litekanyetso tsa tlhahiso. Tse latelang ke litlhaloso tse tloaelehileng le mefuta ea boholo ba lihlahla tse akaretsang tsa bronze:
1. Litlhaloso tse tloaelehileng le mefuta ea boholo
Litlhaloso tsa lihlahla tsa bronze haholo-holo li kenyelletsa bophara ba ka ntle, bophara bo ka hare le bolelele (kapa botenya). Lits'ebetsong tse ikhethileng, litlhaloso le boholo ba lihlahla li hloka ho khethoa ho latela litlhoko tsa moralo oa lisebelisoa le maemo a ts'ebetso.
(1) Bophara ba ka ntle (D)
Bophara ba ka ntle hangata bo fapana ho tloha ho 20mm ho isa ho 500mm. Ho itšetlehile ka litlhoko tsa boholo ba thepa e sebelisoang, bophara bo boholo bo ka ntle bo ka sebelisoa.
Litlhaloso tse tloaelehileng li kenyelletsa: 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 300mm, 400mm.
(2) Bophara ba ka hare (d)
Bophahamo bo ka hare bo bolela boholo ba sehlahla se ka hare ho sefate, seo hangata se leng se senyenyane ho feta bophara ba ka ntle ho etsa bonnete ba hore ho hlaka ka shaft ho loketse.
Mefuta e tloaelehileng ea bophara ba ka hare: 10mm, 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 250mm.
(3) Bolelele kapa botenya (L kapa H)
Bolelele ka kakaretso bo pakeng tsa 20mm le 200mm, 'me bo lokisoa ho latela litlhoko tsa thepa.
Boholo ba bolelele bo tloaelehileng: 20mm, 50mm, 100mm, 150mm, 200mm.
(4) Botenya ba lebota (t)
Botenya ba lerako la bushing ea borone hangata bo amana le bophara bo ka hare le bophara bo ka ntle. Litlhaloso tse tloaelehileng tsa botenya ba lebota ke: 2mm, 4mm, 6mm, 8mm, 10mm.2. Litekanyetso tse tloaelehileng tsa boholo
Boholo ba lihlahla tsa bronze hangata bo latela litekanyetso tse itseng, tse kang GB (tekanyetso ea Sechaena), DIN (Tekanyetso ea Jeremane), ISO (tekanyetso ea machaba), joalo-joalo. Mona ke litekanyetso tse tloaelehileng le mehlala ea boholo:
(1) GB/T 1231-2003 - Copper alloy casting bushings
Tekanyetso ena e totobatsa boholo le moralo oa lihlahla tsa bronze mme e sebetsa ho lisebelisoa tse akaretsang tsa mochini.
Ka mohlala: bophara ba ka hare 20mm, bophara ba ka ntle 40mm, bolelele ba 50mm.
(2) DIN 1850 - Lihlahla tsa alloy tsa koporo
Tekanyetso ena e sebetsa ho lihlahla tse thellang ka har'a lisebelisoa tsa mochini, tse nang le boholo bo tlohang kahare ho bophara ba 10mm ho isa ho 500mm le botenya ba lebota lipakeng tsa 2mm le 12mm.
(3) ISO 3547 - Li-bearings tse thellang le lihlahla
Tekanyetso ena e sebetsa ho moralo le boholo ba li-bearings tse thellang le lihlahla. Mefuta e tloaelehileng e kenyelletsa bophara ba ka hare 20mm, 50mm, 100mm, 150mm, joalo-joalo.3. Mefuta e tloaelehileng ea lihlahla le boholo
Ho ipapisitse le litlhoko tse fapaneng tsa moralo, lihlahla tsa bronze li ka ba tsa mefuta e fapaneng. Mefuta e tloaelehileng ea lihlahla le boholo ke tse latelang:
(1) Sehlahla se tloaelehileng sa boronse se chitja
Ka hare bophara: 10mm ho 500mm
Bophara ba ka ntle: Ho tsamaellana le bophara bo ka hare, tse tloaelehileng ke 20mm, 40mm, 60mm, 100mm, 150mm, joalo-joalo.
Length: Hangata ho tloha 20mm ho 200mm
(2) Sehlahla sa bronze sa mofuta oa flange
Sehlahla sa mofuta oa flange se entsoe ka lesale le hlaheletseng (flange) bakeng sa ho kenya habonolo le ho tiisa.
Ka hare bophara: 20mm ho 300mm
Bophara ba ka ntle: Hangata e kholo ho feta makhetlo a 1.5 bophara ba ka hare
Botenya ba flange: Hangata 3mm ho 10mm
(3) Sehlahla se bulehileng sa boronse
Sehlahla sa semi-open bushing se etselitsoe hore se bulehe halofo, se loketse liketsahalo tseo ho seng bonolo ho li qhaqholla ka botlalo.
Ka hare bophara: 10mm ho 100mm
Bophara ba ka ntle: bo amanang le bophara bo ka hare, hangata bo na le phapang e nyane.4. Litlhoko tse khethehileng le ho iketsetsa
Haeba boholo bo tloaelehileng bo sa tšoanelehe bakeng sa litlhoko tse khethehileng, boholo ba sehlahla sa borone bo ka etsoa ho latela litlhoko tsa moralo. Ha ho etsoa mokhoa oa hau, lintlha tse kang litlhoko tsa mojaro oa thepa, tikoloho ea ho sebetsa (joalo ka mocheso, mongobo, ho senya), le maemo a ho lubrication.5. Litlhaloso tse tloaelehileng tsa thepa
Lisebelisoa tse atisang ho sebelisoa bakeng sa lihlahla tsa bronze ke:
Aluminium bronze (e kang CuAl10Fe5Ni5): e loketse moroalo o phahameng le maemo a phahameng a ho hanyetsa.
Boronse ba thini (joalo ka CuSn6Zn3): e loketse ho hanyetsa kutu le maemo a tlase a likhohlano le ho apara.
Bronze e etellang pele (joalo ka CuPb10Sn10): e loketse libaka tsa ho itlotsa tse nang le coefficient e tlase ea likhohlano.6. Tafole ea litšupiso
Lintlha tse latelang ke tse ling tse tloaelehileng tsa boholo ba lihlahla tsa bronze:
Botenya ba ka hare (d) Botenya ba ka ntle (D) Bolelele (L) Botenya ba lebota (t)
20 mm 40 mm 50 mm 10 mm
40 mm 60 mm 80 mm 10 mm
100 mm 120 mm 100 mm 10 mm
150 mm 170 mm 150 mm 10 mm
200 mm 250 mm 200 mm 10 mm
Kakaretso:
Litlhaloso le boholo ba lihlahla tsa bronze li fapana ho latela maemo a ts'ebeliso. Bophara ba ka hare bo tloaelehileng, bophara ba ka ntle, bolelele, le botenya ba lebota li ka har’a moeli o itseng, ’me boholo bo loketseng bo ka khethoa ho ea ka litlhoko. Lits'ebetsong tsa 'nete, boholo ba bushing ea borone bo hloka ho khethoa ho latela litlhoko tsa moralo oa lisebelisoa le maemo a mojaro,' me e ka etsoa ka mokhoa o ikhethileng ha ho hlokahala.
