  秸稈顆粒機廠家:顆粒機壓棍軸承燒壞的緣由有哪些?
  Straw granulator manufacturer: What are the causes of burnout of the press rod bearing of granulator?
  秸稈顆粒機壓棍軸承總是燒壞的緣由有哪些?濟南龍騰新能源重型設備有限公司為你支招,秸稈顆粒機壓棍軸承老是壞怎樣辦?要想理解秸稈顆粒機的壓棍軸承老是壞的緣由,首先要理解,秸稈顆粒機壓棍的構造:壓輥主要由壓輥偏心軸、壓輥殼、壓棍軸承等組成。壓輥的作用是將物料擠壓入模孔,在模孔中受壓成型。
  What are the reasons for the burnout of the stick bearing of the straw granulator? Jinan Longteng New Energy Heavy Equipment Co., Ltd. for your enlistment, straw granulator pressure stick bearing is always bad how to do? In order to understand the reason why the pressing rod bearing of straw granulator is always bad, first of all, we should understand the structure of the pressing rod of straw granulator: the pressing roll is mainly composed of eccentric axis of the pressing roll, the pressing roll shell, the pressing rod bearing and so on. The function of the roller is to squeeze the material into the die hole and press it into the die hole.
  一、秸稈顆粒機壓棍軸承老是燒壞指的就是壓棍軸承燒壞,緣由有兩個:
  First, the stick bearing of the straw granulator is always burned out, which means that the stick bearing is burned out for two reasons:
  1、溫度高。由于壓棍軸承高速運轉,遭到壓棍偏心力的影響,壓棍軸接受到摩擦力和與磨具擠壓力的雙重影響,溫度自然升高,因而軸承的光滑就十分重要,濟南龍騰新能源重型設備的平模顆粒機和立式環模顆粒機均采用了壓棍自動光滑技術,均勻每30分鐘,自動打油20秒,有效地處理了因人工打油,操作工偷懶而疏忽光滑,燒壞軸承的現 象發作。
  1. High temperature. Because of the influence of eccentricity of pressure bar on the high speed running of pressure bar bearing, the pressure bar shaft receives the double influence of friction force and extrusion force of abrasive tool, and the temperature increases naturally, so the smoothness of bearing is very important. The automatic smoothness of pressure bar is adopted in both the flat die granulator and the vertical ring die granulator of Jinan Longteng New Energy Heavy Equipment. Technology, even every 30 minutes, automatic oil for 20 seconds, effectively deal with the occurrence of artificial oil, operator laziness and negligence of smooth, burned bearings.
  2、壓輥在高速旋轉過程中,必然會有縫隙,使木屑中的細小粉末飛入壓輥中,在壓棍軸承中與油脂混合,構成摩擦和保溫,不利于散熱,形成軸承燒壞,濟南冠貝機械的環模木屑顆粒機,加裝了除塵風機,有效地防止了粉末的進入,還能給壓棍、模具降溫的作用。
  2. In the process of high-speed rotation, there will inevitably be cracks in the pressing roll, so that the fine powder in sawdust flies into the pressing roll, and is mixed with oil in the pressing rod bearing, which constitutes friction and heat preservation, is not conducive to heat dissipation, and causes bearing burnout. The ring-shaped sawdust granulator of Jinan crown shellfish machinery is equipped with dust-removing fan, which effectively prevents the powder. Enter, but also to pressure bar, mold cooling effect.
  二、秸稈顆粒機內部的壓棍軸承的毛病現象普通表現為兩種,一是軸承裝置部位溫渡過高,二是軸承運轉中有噪音。
  2. There are two kinds of faults in the pressure bar bearing of the straw granulator. One is that the temperature of the bearing device is too high, the other is that there is noise in the operation of the bearing.
  1.軸承溫渡過高
  1. Bearing temperature is too high
  壓棍在運轉中,裝置軸承的部位允許有一定的溫度,當用手撫摸機構外殼時,應以不覺得燙手為正常,反之則標明軸承溫渡過高。
  In the operation of the pressure stick, the bearing part of the device is allowed to have a certain temperature. When touching the shell of the mechanism with hand, it should be normal not to feel hot hands, otherwise it should indicate that the temperature of the bearing is too high.
  形成軸承溫渡過高的緣由有:光滑油質量不契合請求或蛻變,光滑油粘渡過高;機構裝配過緊(間隙缺乏);軸承裝配過緊;軸承座圈在軸上或殼內轉動;負荷過大;軸承堅持架或滾動體碎裂等。
  The reasons for excessive bearing temperature are as follows: the quality of smooth oil does not meet the requirements or degeneration, and the smooth oil sticks excessively high; the mechanism assembly is too tight (lack of clearance); the bearing assembly is too tight; the bearing seat ring rotates on the shaft or in the shell; the load is too large; the bearing adherence frame or the rolling body is fragmented, etc.
  2.軸承噪音
  2. Bearing noise
  木屑顆粒機壓棍軸承在工作中允許有細微的運轉響聲,假如響聲過大或有不正常的噪音或撞擊聲,則標明軸承有毛病。
  Slight running noise is allowed in the work of the pressure bar bearing of the sawdust granulator. If the noise is too loud or there is abnormal noise or impact noise, it indicates that the bearing is defective.
  壓棍軸承產生噪音的緣由比擬復雜,其一是軸承內、外圈配合外表磨損。由于這種磨損,毀壞了軸承與殼體、軸承與軸的配合關系,招致軸線偏離了正確的位置,在軸在高速運動時產生異響。當軸承疲倦時,其外表金屬剝落,也會使軸承徑向間隙增大產生異響。此外,軸承光滑缺乏,構成干摩擦,以及軸承破碎等都會產生異常的聲響。軸承磨損松曠后,堅持架松動損壞,也會產生異響。

  The causes of noise produced by pressure bar bearings are comparatively complex. One is that the inner and outer rings of bearings are worn together with the outer rings. Because of this kind of wear and tear, it destroys the matching relationship between bearing and shell, bearing and shaft, causes the axis to deviate from the correct position, and produces abnormal sound when the shaft moves at high speed. When the bearing is tired, its external metal peeling will also make the radial clearance of the bearing increase and produce abnormal sound. In addition, the lack of smooth bearings, dry friction, and bearing breakage will produce abnormal sound. After bearing wear and tear is loose, adherence frame will be loose and damaged, and abnormal noise will also occur.
  三、壓棍軸承的損傷
  3. Damage of Pressure Rod Bearing
  壓棍軸承拆卸檢查時,可依據軸承的損傷狀況判別軸承的毛病及損壞緣由。
  When disassembling and inspecting the pressure bar bearing, the fault of the bearing and the cause of the damage can be distinguished according to the damage condition of the bearing.
  1.滾道外表金屬剝落
  1. Metal spalling on raceway surface
  軸承滾動體和內、外圈滾道面上均接受周期性脈動載荷的作用,從而產生周期變化的接觸應力。當應力循環次數到達一定數值后,在滾動體或內、外圈滾道工作面上就產生疲倦剝落。假如軸承的負荷過大,會使這種疲倦加劇。另外,軸承裝置不正、軸彎曲,也會產生滾道剝落現象。
  The bearing rolling element and the raceway surfaces of inner and outer rings are subjected to periodic fluctuating loads, resulting in periodically varying contact stresses. When the number of stress cycles reaches a certain value, fatigue spalling occurs on the working face of rolling body or inner and outer raceway. If the load of the bearing is too large, it will aggravate the fatigue. In addition, if the bearing device is not correct and the shaft is bent, the raceway peeling will also occur.
  軸承滾道的疲倦剝落會降低軸的運轉精度,使機構發作振動和噪聲。
  The fatigue and spalling of bearing raceway will reduce the operation accuracy of the shaft and cause the vibration and noise of the mechanism.
  2.軸承燒傷
  2. Bearing Burns
  燒傷的軸承其滾道、滾動體上有回火色。燒傷的緣由普通是光滑缺乏、光滑油質量不契合請求或蛻變,以及軸承裝配過緊等冠貝機械撰寫此文。
  Burned bearings have tempering color on their raceways and rollers. The causes of burns are usually lack of smoothness, quality of smoothness oil does not meet the requirements or metamorphosis, and bearing assembly is too tight and other crown shellfish machinery to write this article.
  3.塑性變形
  3. Plastic Deformation
  軸承的滾道與滾子接觸面上呈現不平均的凹坑,闡明軸承產生塑性變形。其緣由是軸承在很大的靜載荷或沖擊載荷作用下,工作外表的部分應力超越資料的屈從極限,這種狀況普通發作在低速旋轉的軸承上。
  There are uneven pits on the contact surface between raceway and roller of bearing, which explains the plastic deformation of bearing. The reason is that under the action of large static load or impact load, part of the stress on the working surface exceeds the yield limit of the data, which usually occurs on bearings rotating at low speed.
  4.軸承座圈裂紋
  4. Bearing Ring Cracks
  軸承座圈產生裂紋的緣由可能是軸承配合過緊,軸承外國或內圈松動,軸承的容納件變形,裝置軸承的外表加工不良等。
  The causes of cracks in bearing seat rings may be the tight matching of bearings, the loose outer or inner rings of bearings, the deformation of bearing accommodation parts, and the poor processing of bearing appearance.
  5.堅持架碎裂
  5. Sticking frame fragmentation
  其緣由是光滑缺乏,滾動體破碎,座圈傾斜等冠貝機械撰寫此文。
  The reason is the lack of smoothness, the crushing of rolling bodies and the inclination of seat rings.
  6.堅持架的金屬粘附在滾動體上
  6. The metal of the holder adheres to the rolling element.
  可能的緣由是滾動體被卡在堅持架內或光滑缺乏。
  The possible reason is that the rollers are stuck in the stick frame or lack of smoothness.
  7.座圈滾道嚴重磨損
  7. Serious wear of raceway of seat ring
  可能是座圈內落入異物,光滑油缺乏或光滑油牌號不適宜。
  It may be that foreign bodies fall into the seat ring, and the smooth oil is not enough or the smooth oil brand is not suitable.
  所以說,影響軸承壽命的緣由十分的多,假如發現軸承損壞我們時間依照損壞的可能性去排查,先處理問題。假如不斷不能處理的能夠找 秸稈顆粒機廠家處理!
  So, there are many reasons that affect the life of bearings. If we find that the bearings are damaged, we first investigate according to the possibility of damage, and first deal with the problem. If we can't deal with it continuously, we can find the manufacturer of straw granulator to deal with it.
