    首頁:公司動態 >> 托輥生產行業的發展變化介紹

    托輥生產技術雖然已經基本成熟,但是由于我國地域廣泛,托輥生產存在分散的弊端,往往一些發展新趨勢不能很快的為人熟知并推廣生產,我公司一直在關注托輥發展的新趨勢,希望為廣大的生產商提供信息,也為使用者帶來福音。   一、前置式托輥   三輥式前置式托輥,其主要特點為:不存在輥間間隙,適當減小中間輥長度,并且相對地減小中間托輥載荷,輸送帶與二側輥幾乎沿母線全長接觸,有利于輸送帶對中,延長了中間輥軸承壽命,使其整體托輥壽命延長。   二、深溝槽軸承   高強度輸送機托輥配件偏重于采用重型錐形滾珠軸承和深溝滾珠軸承。目前英國采用專用大游隙大滾珠深槽軸承。德國采用凹槽大游隙軸承。當軸承內孔為¢17-40mm時,軸向游隙量100-150um. 潤滑油深入槽內,即使帶進部分灰塵,也不易卡死。它的使用壽命是普通軸承的3倍。   三、深槽角托輥和表面噴涂托輥   目前槽型托輥已不能滿足輸送機,更加偏重使用深槽角托輥和中間不等長托輥,使托輥承載趨于均勻。托輥的另一種趨勢是應用非鋼性材料和在鋼材表面噴涂化工材料,如聚胺酯防護層托輥,這種材料對金屬材料具有較強的附著力,還具有抗腐蝕、抗壓縮、抗沖擊等特性。還有用玻璃鋼制成的托輥,外層用耐磨碳黑增強,我國已經開始生產。   四、無上托輥輸送——氣墊式帶式輸送機   我國已有若干專業機械廠生產固定和可移式氣墊式帶式輸送機。采用氣墊技術原理,將機械摩擦變成了氣體摩擦,取消了上托輥。   這些新動態都很有可能帶來托輥業的巨變,而且隨著托輥對科學技術依賴加強,可以預見高科技托輥將成為托輥行業的主流。 Roller production technology has been basically mature, but because our country widely, insufficiency of dispersed roller production, tend to develop some new trend can not be quickly familiar and promote production, my company has been focused on the new tendency of the development of the roller, hope for the overwhelming majority of manufacturers to provide information, and bring the Gospel to users. A, superposed roller three-high superposed roller, its main characteristic is: there is no clearance between roller and reduced intermediate roll length, and relatively reduced intermediate roller load, conveyor belt and two side roller contact almost along the bus bar length, is advantageous to the conveyor belt for the extended the intermediate roller bearing life, make the whole roller life extension. Two, deep groove bearing high strength conveyor roller fittings are weighted by heavy cone ball bearing and deep groove ball bearing. Currently the UK adopts special large clearance ball deep groove bearing. Germany USES grooved big gap bearings. When the bearing inner hole is ¢17-40 mm, axial clearance volume 100-150 um. The deep groove of lubricating oil, even take part into the dust, not easy also. Its service life is three times as long as the normal one. Three, readjust the Angle of roller and roller surface paint The trough type roller already cannot satisfy conveyor, more emphasis on the use of deep groove Angle roller and middle long roller, roller bearing tend to be more uniform. Roller another trend is the application of the rigid materials and on the steel surface spraying chemical materials, such as polyurethane protective coating roller, the material of metal materials with strong adhesion, also has corrosion resistance, compression resistance, impact resistance and other properties. There is also a roll made of fiberglass, the outer layer is strengthened by wear-resisting carbon black, and our country has begun to produce. Four, supreme roller conveyor, air cushion belt conveyor We have already had a number of professional machinery factory production of fixed and movable type air cushion belt conveyor. Using the principle of cushion technology, the friction of mechanical friction becomes gas friction, and the upper roller is cancelled. All of these new dynamic is likely to bring the roller industry transformation, and along with the roller to rely on strengthening science and technology, high-tech foreseeable roller will become the mainstream of roller industry.
