一種防護型扭簧
本技術涉及彈簧領域,尤其涉及一種防護型扭簧。
技術介紹
彈簧是一種利用彈性來工作的機械零件。用彈性材料制成的零件在外力作用下發(fā)生形變,除去外力后又恢復原狀。亦作“彈簧”。一般用彈簧鋼制成。彈簧的種類復雜多樣,按形狀分,主要有螺旋彈簧、渦卷彈簧、板彈簧、異型彈簧等。對于彈簧行業(yè)來說,長期以來形成了低檔普通彈簧供過于求,高檔產(chǎn)品(高強度、高應力、異性件、特種材料)供不應求的被動形勢。我國彈簧行業(yè)的產(chǎn)量已趨于飽和,據(jù)專家統(tǒng)計我國彈簧年生產(chǎn)量已達40億件,各類彈簧產(chǎn)品共有21個大類,1600多個品種,主要有氣門彈簧、懸架彈簧、膜片彈簧、減震彈簧、液壓彈簧、油泵彈簧、碟形彈簧、高溫彈簧、卡簧、拉簧、扭簧、壓簧、渦卷簧以及異性彈簧等。彈簧行業(yè)在“八五”、“九五”期間發(fā)展是比較快的,尤其是上海、天津、廣州、山東、長春、重慶等地區(qū)發(fā)展較快,其他地區(qū)也有不同程度的發(fā)展,總的來說比其他行業(yè)要好一些。汽車、摩托車、助動車、內(nèi)燃機、電氣、儀器等還要發(fā)展,這些行業(yè)的發(fā)展將會帶動彈簧行業(yè)的發(fā)展。彈簧制作完成后需要進行壓力測試,扭轉彈簧(TorsionSpring)為所有彈簧類別中設計原理較為復雜的一種,型式的變化亦相當活潑,故設計時所涉及的理論也最為繁瑣;現(xiàn)有扭簧在承載過程中經(jīng)常發(fā)生斷裂或者固定端頭脫落的情況,給使用者帶來較大不便。基于以上原因,需要一種防護型扭簧被設計出來,通過設置鋼絲繩,可以很好的防止扭簧斷裂后,造成設備的脫落或滑脫;通過設置焊接加強點,可以很好地保護端頭的抗扭能力,通過設置定螺釘,在扭簧和外接設備連接穩(wěn)定后,擰上緊固螺釘,避免外接設備輕易脫落,提 ...
