  Straw granulator manufacturer: What are the causes of burnout of the press rod bearing of granulator?
  秸秆颗粒机压棍轴承总是烧坏的缘由有哪些?济南龙腾新能源重型设备有限公司为你支招,秸秆颗粒机压棍轴承老是坏怎样办?要想理解秸秆颗粒机的压棍轴承老是坏的缘由,首先要理解,秸秆颗粒机压棍的构造:压辊主要由压辊偏心轴、压辊壳、压棍轴承等组成。压辊的作用是将物料挤压入模孔,在模孔中受压成型。
  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、秸秆颗粒机压棍轴承老是烧坏指的就是压棍轴承烧坏,缘由有两个:
  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、温度高。由于压棍轴承高速运转,遭到压棍偏心力的影响,压棍轴接受到摩擦力和与磨具挤压力的双重影响,温度自然升高,因而轴承的光滑就十分重要,济南龙腾新能源重型设备的平模颗粒机和立式环模颗粒机均采用了压棍自动光滑技术,均匀每30分钟,自动打油20秒,有效地处理了因人工打油,操作工偷懒而疏忽光滑,烧坏轴承的现 象发作。
  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、压辊在高速旋转过程中,必然会有缝隙,使木屑中的细小粉末飞入压辊中,在压棍轴承中与油脂混合,构成摩擦和保温,不利于散热,形成轴承烧坏,济南冠贝机械的环模木屑颗粒机,加装了除尘风机,有效地防止了粉末的进入,还能给压棍、模具降温的作用。
  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、秸秆颗粒机内部的压棍轴承的毛病现象普通表现为两种,一是轴承装置部位温渡过高,二是轴承运转中有噪音。
  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.轴承温渡过高
  1. Bearing temperature is too high
  压棍在运转中,装置轴承的部位允许有一定的温度,当用手抚摸机构外壳时,应以不觉得烫手为正常,反之则标明轴承温渡过高。
  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.
  形成轴承温渡过高的缘由有:光滑油质量不契合请求或蜕变,光滑油粘渡过高;机构装配过紧(间隙缺乏);轴承装配过紧;轴承座圈在轴上或壳内转动;负荷过大;轴承坚持架或滚动体碎裂等。
  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.轴承噪音
  2. Bearing noise
  木屑颗粒机压棍轴承在工作中允许有细微的运转响声,假如响声过大或有不正常的噪音或撞击声,则标明轴承有毛病。
  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.
  压棍轴承产生噪音的缘由比拟复杂,其一是轴承内、外圈配合外表磨损。由于这种磨损,毁坏了轴承与壳体、轴承与轴的配合关系,招致轴线偏离了正确的位置,在轴在高速运动时产生异响。当轴承疲倦时,其外表金属剥落,也会使轴承径向间隙增大产生异响。此外,轴承光滑缺乏,构成干摩擦,以及轴承破碎等都会产生异常的声响。轴承磨损松旷后,坚持架松动损坏,也会产生异响。
                               秸秆颗粒机厂家
  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、压棍轴承的损伤
  3. Damage of Pressure Rod Bearing
  压棍轴承拆卸检查时,可依据轴承的损伤状况判别轴承的毛病及损坏缘由。
  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.滚道外表金属剥落
  1. Metal spalling on raceway surface
  轴承滚动体和内、外圈滚道面上均接受周期性脉动载荷的作用,从而产生周期变化的接触应力。当应力循环次数到达一定数值后,在滚动体或内、外圈滚道工作面上就产生疲倦剥落。假如轴承的负荷过大,会使这种疲倦加剧。另外,轴承装置不正、轴弯曲,也会产生滚道剥落现象。
  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.
  轴承滚道的疲倦剥落会降低轴的运转精度,使机构发作振动和噪声。
  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.轴承烧伤
  2. Bearing Burns
  烧伤的轴承其滚道、滚动体上有回火色。烧伤的缘由普通是光滑缺乏、光滑油质量不契合请求或蜕变,以及轴承装配过紧等冠贝机械撰写此文。
  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.塑性变形
  3. Plastic Deformation
  轴承的滚道与滚子接触面上呈现不平均的凹坑,阐明轴承产生塑性变形。其缘由是轴承在很大的静载荷或冲击载荷作用下,工作外表的部分应力超越资料的屈从极限,这种状况普通发作在低速旋转的轴承上。
  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.轴承座圈裂纹
  4. Bearing Ring Cracks
  轴承座圈产生裂纹的缘由可能是轴承配合过紧,轴承外国或内圈松动,轴承的容纳件变形,装置轴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.坚持架碎裂
  5. Sticking frame fragmentation
  其缘由是光滑缺乏,滚动体破碎,座圈倾斜等冠贝机械撰写此文。
  The reason is the lack of smoothness, the crushing of rolling bodies and the inclination of seat rings.
  6.坚持架的金属粘附在滚动体上
  6. The metal of the holder adheres to the rolling element.
  可能的缘由是滚动体被卡在坚持架内或光滑缺乏。
  The possible reason is that the rollers are stuck in the stick frame or lack of smoothness.
  7.座圈滚道严重磨损
  7. Serious wear of raceway of seat ring
  可能是座圈内落入异物,光滑油缺乏或光滑油牌号不适宜。
  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.
  所以说,影响轴承寿命的缘由十分的多,假如发现轴承损坏我们时间依照损坏的可能性去排查,先处理问题。假如不断不能处理的能够找 秸秆颗粒机厂家处理!
  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.
