Pulley taraiwa

(1) Ko te anga o te pahū he matatau me nga tawhā whaitake. Ko te kaupapa rorohiko motuhake e whakatau ana i te diameter o te toki, te matotoru o te tinana pahū, te matotoru o te kōpae mutunga, Ko te tuunga o te whiri whiri porowhita ka whakarite kia iti te ahotea me te iti rawa o nga huringa.

(2) The pulley is divided into three kinds such as Light-duty, Medium -duty and Heavy-duty according to the carrying capacity,and the drum body of Light-duty and Medium-duty are welded with steel plate, the drum body of Heavy-duty is welded with cast iron plate .otherwise, Light-duty: the shaft and the wheel hub are connected by single key ; Medium-duty: the shaft and the wheel hub are connected by expansion sleeve ; Heavy duty: shaft and wheel hub is connecteed by expansion sleeve, There are one -side -out shaft and both-sides-out shaft.

(3) Nga tikanga welding: ko te whakamarumaru o te hau me te pewa kua rukuhia.

(4) Ko te hiku porohita me te waahi roa o te tinana o te pulley me nga waahanga maka ka kitea e te ultrasonic kia rite ki nga whakaritenga.

(5) Hei whakanui ake i te waku me te aukati i te paheke o te whitiki kawe, ka taea te hipoki te mata o te whana taraiwa ki te rapa herringbone, te rapa ahua taimana me te rapa uku.
