Hunhu hwe gaiters

Hunhu hwe gaiters

Nzira dzekufambisa matanda dzinogona kuenderera kana kupindirana. Nekuenderera mberi kwekufamba, iyo log inofamba ichienderera uye yakaenzana panguva yekushanda uye isina basa sitiroko yegedhi furemu. Nekufamba kunopindirana, irogi rinongofamba chete kune chimwe chikamu chekutenderera kwega kwe shaft - nguva nenguva. Kufamba kwepakati kunogona kuitwa panguva yekushanda kana kusashanda kwegedhi.

Kuenderera mberi kwekufamba kunoshandiswa mukukurumidza-kufamba-double-decker varindi vemikova vane nhamba yakawanda yekuchinja; intermittent movement - mukunonoka-kufamba gaiters ane nhamba yakaderera yezvimurenga.

Kuti uteme matanda pamugero, zvinodikanwa kuti masaha ari mugomba ave nekumwe kutsetseka. Hukuru hwemutsetse mutsetse unotemerwa neinoenderera inofamba patani: 

y: Δ / 2 + (1/2) mm; kwekufamba kwepakati panguva yekushanda sitiroko y = 2 kusvika 5 mm; yekufamba kwepakati panguva yekusagona y = Δ + (1/2) mm.

Heino, y ndiyo nagi yesaha mufuremu, mm; Δ - kufamba kwegogi kana danda panguva imwe kutenderera kwegedhi roller, mm.

Mufananidzo 1: Inclinometer yekuyera kuwanda kwekurerekera kwesaha

Iyo overhang (kurerekera) yesaha inotariswa ne overhang gauge. Iyo overhang gauge ine simbi mbiri dzakabatanidzwa pajoinhi kumusoro, uye kumucheto kwezasi kune tambo yakachinjika ine chirevo chekupfuura kwetensioning screw ne butterfly nut. Chiyero chemweya chinomisikidzwa pane imwe simbi tambo. Kurerekera kunoverengwa mumm pakureba kweforemu sitiroko pachiyero, icho chiri pazasi pechishongedzo (fig. 1).

Kuti ucheke mapuranga kana matanda ehupamhi hunodiwa pakati pemasaha mufuremu, kuisa (kuparadzanisa) kunopinzwa, hupamhi hunonyatsoenderana nehupamhi hwedanda rinofanira kutemwa.

Spanung seti yemasaha mufuremu ine nhambwe dzakatarwa pakati pavo, pahwaro hwekuti matanda akachekwa ezviyero zvinodiwa anowanikwa. Ukobvu hwekuisa hunotarwa maererano nechimiro S = a + b + 2c mm. Apo S ndiko kukora kwechipinzwa; a - nominal board ukobvu; b - kuwandisa pakuomeswa; c - ukuru hwekupararira kwemazino kune rumwe rutivi. 

Insets (fig. 2) yakagadzirwa nehuni yakaoma (ine huwandu hwe15% humidity) birch, chub, beech, madota.

Kuomeswa kwemvumo kunowedzerwa kuhupamhi uye kureba zviyero zvesawn coniferous huni - pine, spruce, fir, misidhari uye larch, iyo inowanikwa panguva yakasanganiswa kucheka (ine tangential-radial kurongeka kwegore negore) yematanda akanyorova kana pakucheka kunyorova. matanda akachekwa kuti ave nechokwadi chekuwana zviyero zvinodiwa zvezvinhu munzvimbo yakaoma.

Huni dzakachekwa dzemaconifers akaiswa akakamurwa kuita mapoka maviri zvichienderana nehukuru hwekuomeswa kwakawandisa: yekutanga inosanganisira pine, spruce, misidhari uye fir, yechipiri inosanganisira larch.

Ukobvu nehupamhi huyero hwematanda akachekwa ane hunyoro hwekutanga hunodarika 30% uye hunyoro hwekupedzisira hwe15% zvinopihwa muTafura 1.

Paunenge uchicheka matanda kana matanda ane hunyoro huri pasi pe30%, ukuru hwehuwandu hunoverengwa semusiyano pakati pehukuru hwekuwedzerwa kwekukumbira kwekupedzisira hunyoro uye kuwanda kwehunyoro huripo hwehuni. Sawn huni dzemhando dzehuni dzakaoma, dzinosanganisira beech, hornbeam, birch, oak, elm, mepu, madota, aspen, poplar, dzakakamurwa zvichienderana nehuwandu hwekuomeswa mumapoka maviri kune tangential kutungamira uye mumapoka maviri eiyo radial gwara.
