        山东力王起重机械有限公司(http://www.ylqzjpj.com/)一路走来兢兢业业,用劳动证明:科学不是可以不劳而获的,诚然,在科学上除了汗流满面是没有其他获得成功的方法的;热情也罢,幻想也罢,以整个身心去渴望也罢,都不能代替劳动。
Shandong Longteng Hoisting Machinery Co., Ltd. along the way be conscientious and do one's best, with labor certification: True science is not can grow, in science, in addition to sweat streamed down one's face. There is no other successful method; passion, fantasy or, with the whole body to want, are not a substitute for labor.
      行车配件在机械中占据重要地位,根据电动机负载转矩和发热条件选定的主电动机,其转速都高于轧辊所要求的转速。为此在主机列中装设减速机,以便将电动机转速变为轧辊所需要的转速。这样还可以降低主电动机与飞轮的造价。主减速机是行车配件的关键设备。由于行车配件主减速机的工作环境恶劣、工况复杂,在行车配件过程中每一次咬钢、甩钢都伴随着较大的冲击,这些因素会导致减速机性能变差,甚至出现故障,影响设备的作业率,因此需要采取措施来延长主减速机的使用寿命。给主减速机的润滑油加入添加剂是一种简单的方法,且便于现场实现。而在润滑油中加入添加剂对设备的运行状况影响如何需要找出一种有效和简单的方法来实现。
        Vehicle fittings occupy an important position in the machinery, according to the motor load of main motor torque and heating conditions are selected, the speed is higher than the required speed of roller. This install reducer column in the host, so that the motor speed change needed to roll speed. It can reduce the cost of the motor and the flywheel. Main reducer is the key equipment of vehicle accessories. Since the driving parts of the main reducer of poor working conditions, complicated working condition, in the driving parts in every bite, rejection of steel with a greater impact, these factors will lead to poor performance and speed reducer, fault occurs, the effects of equipment operation rate, service life is therefore need to take steps to extend the main reducer. The main reducer for lubricating oil additive is a simple method, convenient on-site implementation. Effect of additives on the join operation status of equipment in the lubricating oil to need to find an effective method and simple to implement.
       行车配件中的制动器使机械中运动件的速度降低或停止的装置。主要由制动架、制动件和驱动装置3部分组成。在设备的高速轴上固定安装一个轮或盘,而在机架上安装与之相配合作用的盘、带或闸瓦,其工作原理是由外加作用力产生制动力矩,克服驱动力矩; 消耗运动件之动能,致使运动减速或停止。大型矿井提升机的安全制动器通常装在设备工作部分的低速卷筒轴上。常用的制动器分为摩擦式和非摩擦式两大类。摩擦式制动器依靠制动件与运动件之间的摩擦力制动。动作过程与块式制动器相似,所不同的是它用收紧皮带的方法进行制动。一般带式制动器产生的制动力矩较大,所占空间也大,故多用于大、中型机械的制动。液压制动器是一种浸于油中的制动器。该制动器电磁铁的电磁线圈通电后,动铁芯(衔铁)的吸力推动推杆驱动活塞运动, 通过油道使油增压从而使制动瓦块动作。由于其运动部件浸于油中,润滑条件好,动作平稳,制动力矩和行程可以调节。
      Unit brake driving parts in the mechanical moving parts reduce speed or stop. Is mainly composed of a brake rack, braking and driving device is composed of 3 parts. A wheel or disk is fixed on the high speed shaft equipment installation, and is matched with the role of the disk, tape or shoe on the machine frame, its working principle is to produce brake moment by the extra force, overcome the driving torque; consumption of kinetic energy movement, the movement to slow down or stop. Large mine hoist safety brake machine is usually installed in the equipment working part of the low speed drum shaft. The common brake classified friction and non friction type two categories. The friction brake on braking force brake parts and moving parts. Action process is similar to the block brake, the difference is it by tightening the belt brake. General band brake braking torque produced larger, the occupied space is large, so much for big, medium-sized mechanical brake. Hydraulic brake is a dip in the oil brake. Electromagnetic coils of the electromagnetic brake electromagnet energized, moving core (armature) force pushes the push rod to drive the piston through the oil channel so that the oil pressure, so that the brake pad action. Because of its moving partsImmersed in oil, a good lubrication condition, smooth movement, braking torque and stroke can be adjusted.
         命运,不过是失败者无聊的自慰,不过是懦怯者的解嘲。人们的前途只能靠自己的意志、自己的努力来决定。
          Fate, but the loser boring masturbation, but is a weakling of mockery. People in the future can only rely on their own volition, hard to decide.
