Sei Vakasiyana Mukushanduka-shanduka?
- 7x7 Gym Steel Cable: Inosanganisira 7 tambo, imwe neimwe iine 7 waya (dzizere dze49 waya). Tambo imwe neimwe yakakora, uye waya yega yega ine dhayamita yakakura.
- 7x19 Gym Steel Cable: Inoumbwa ne7 tambo, imwe neimwe iine 19 waya (dzizere dze133 waya). Waya dziri mukati metambo yega yega dzakanatswa uye dzakawedzera kuzara.
Core Physical Principle: Kana tambo yesimbi ikakotama, kutsvedza kunoitika pakati petambo uye pakati pewaya. Kukwenenzvera kwewaya uye kuwanda kwadzo, ndiko kuderera kwekusagadzikana kwemukati panguva yekutsvedza, uye kunowedzera kuramba kuneta kuneta. Naizvozvo, iyo 7x19 gadziriso ine diki yekubhenda radius, inoda simba shoma kana ichipfuura nepamusoro pepulley, uye isinganyanyike kugadzira kinks dzisingaperi.
Misiyano yekunzwa panguva yekushandiswa chaiko (Gym)
Pakupfuura nepamusoro-mapaipi madiki
Madhiri anokwenya pamidziyo yekusimbisa muviri (senge-mitsetse yakakwira nemichina yekukwasva) kazhinji ine dhayamita diki (inoda kusvika 50 mm–90 mm). A7x19 simbi tamboinokwana zvakanaka kutenderedza pulley, inopa kutsvedzerera, snag{{0}kunzwa kusununguka; Kusiyana neizvi, 7x7 simbi tambo inosangana nekupokana kunooneka pamapulleys mamwe chete, izvo zvinogona kutungamirira mukupfeka kusina kuenzana pamabearings epulley nekufamba kwenguva.
Cable Twist uye Kudzorera
Paunenge uchiita tambo nhunzi kana tricep ekuwedzera, kana tambo ikamonyoroka pasi pekunetsekana, tambo ye7x19 inopora zvirinani, zvichiita kuti isanyanya mukana wekuti kubata kunopera kuve mapfundo kana coil; iyo 7x7 tambo, zvisinei, yakaoma uye haidzokeri kune yayo yekutanga chimiro nyore mushure mekumonyoroka.
Indasitiri Selection Guide
| Kuenzanisa Chinhu | 7×7 (Yakakwirira-Kuoma) | 7×19 (Yakakwirira-Kuchinjika) |
|---|---|---|
| Kusimba Simba (Kuputsa Mutoro) | Kune dhayamita imwechete yewaya, simba rayo rekupwanya rinoda kusvika 5-8% kumusoro nekuda kwenzvimbo yakakura yesimbi yemuchinjikwa. | Inopa simba rakadzikira zvishoma asi richizadzisa zvizere zvinodikanwa zvekusimba-zvishandiso zvekushandisa (neyakajairwa kuchengetedza chinhu Chikuru kupfuura kana kuenzana negumi). |
| Wear Resistance (Kupokana nekumanikidzwa) | Iyo ine yakanyanya kuoma nzvimbo ine yepamusoro compression kuramba, inokodzera yakatwasuka-kudhonza application kana hombe-diameter madhiramu. | Nzvimbo yaro inogovera kusangana kushushikana zvakaenzana asi inopfeka nekukurumidza zvishoma kupfuura 7 × 7 waya kana ichimhanya ichipokana neakaomarara ekutungamira makwara. |
| Elongation Rate (Elastic Performance) | Low elasticity ine zvishoma deformation pasi pemutoro. | Inopa kurebesa kwechimiro kudiki (0.5%-1%) pasi pekukakavadzana kwekuvandudzwa kwekuvhundutsa-kunotora kuita panguva yekudhonza. |
| Kuneta Hupenyu (Bending Cycles) | Kuita kwakashata-kuneta-kuneta; wire breakage zviri nyore kuitika pasi pekudzokorora kuchinjika. | Inoratidza hupenyu hwakareba hwekukotama-kuneta, kakati wandei iyo ye7 × 7, inoita kuti ive yakakodzera kune yakakwira-kushandiswa kwekutengesa gym nharaunda. |
Industry Selection Recommendations
- Commercial gyms/high-volume studio yekudzidzira munhu: 7x19 steel wire rope ndiyo sarudzo inodiwa. Kuchinjika kwayo kwepamusoro kunowedzera hupenyu hwesevhisi yeese pulley system uye tambo pachayo, uye inopa mamwe mutsara simba rekufambisa panguva yekudzidziswa, zvichikonzera zvirinani mushandisi ruzivo.
- Simple Strength Stations/Linear Dhonza Equipment (eg, deadlift racks, low-pulley machines without pulleys): Kana tambo isingatevedze nzira yakakombama, tambo yewaya ye7x7 inopa mari iri nani uye inoderedza kukanganisa kwekufamba kunokonzerwa nekurebesa kureba.
Yambiro Yakakosha:Iva nechokwadi chekutarisa dhayamita yemukati (R kukosha) yemidziyo yako pulley groove. Kana iyo pulley groove dhayamita isingasviki makumi maviri dhayamita yetambo (semuenzaniso, tambo ye6mm yakabatanidzwa nepulley diki pane 120mm), kushandiswa kwe7x7 tambo kunorambidzwa zvachose; kana zvisina kudaro, kuputsika kwewaya kuchaitika mukati memwedzi 1-2, zvichiunza njodzi yekuchengetedza. Mune mamiriro akadai ane madiki pulleys, 7x19 ndiyo chete yakachengeteka sarudzo.
