Sliding bearing is a very important component of blast furnace blower unit, and improper installation, maintenance, and operation may cause sliding bearing failure. This article mainly discusses the reasons for the failure of the sliding bearing of the blast furnace blower unit, and proposes preventive measures that should be taken during installation, maintenance, and operation.
| 2023 May the Third Week Epen Technical Knowledge: Several Key Points on Improving the Assembly Qual
The assembly quality of sliding bearings will directly affect the service life of diesel engines. Therefore, when repairing diesel engines, attention should be paid to several issues related to the assembly quality of bearings, such as the tightness of the bearing steel back in the seat hole, the pre tightness of the bearing cover bolts, and the inspection of the bearing's protrusion in the seat hole.
| 2023 May the First Week Epen Technical Knowledge: Installation and maintenance of sliding bearings f
The 1 #, 2 #, and 3 # oil transfer pumps at Xingang Station of Dalian Company are multi-stage horizontal split pumps, with pump model KDY790-77 × 3. The pump main bearing is a sliding bearing (TFH75-04/05), and is equipped with angular contact ball bearing to balance the residual axial force. Sliding bearings have stable, reliable, and noise free operation. Under liquid lubrication conditions, the sliding surface is separated by the lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain degree of vibration absorption ability. However, sliding bearings require high installation accuracy, and incorrect installation can cause problems such as bearing heating and vibration. Therefore, how to install and maintain the sliding bearings correctly is the key to the normal operation of the oil pump.
| 2023 April the Fourth Week Epen Technical Knowledge: Application and Maintenance of Sliding Bearings
There are many types of bearings, which can be roughly divided into two categories: rolling bearings; One type is sliding bearings, which are widely used in mine hoists due to their high load-bearing capacity, significant impact resistance and shock absorption effects, low manufacturing cost, and easy disassembly. By analyzing the bearing force and working principle of the sliding shaft of the main and auxiliary shaft gearbox, the cause of bearing damage was found, and corresponding improvement measures were taken. To strengthen the use and maintenance of bearings, so that the sliding bearings of large equipment can operate reliably and stably, and achieve the goal of extending the service life of the sliding bearings.
| 2023 April the Third Week Epen Technical Knowledge: What is the general clearance of sliding bearing
The clearance of sliding bearings is generally 0.01 to 0.02 millimeters. The value range of the sliding bearing clearance is determined according to the accuracy of the parts it is used. For example, the precision of the grinding machine fitting with the main bearing of the lathe indexing head is H7/g6, and the precision of the bearing fitting for agricultural machinery is H11/d11.
| 2023 April the Second Week Epen Technical Knowledge: Scraping and Grinding Technical Requirements an
With the development of market economy and the implementation of national energy policies, equipment in industries such as mining, cement, steel, and electric power are developing towards large-scale, and the demand for large motors is also increasing. Large motor bearings are mostly split radial sliding bearings, mainly made of babbitt alloy. During assembly, scraping and grinding methods are generally used to meet the accuracy requirements and ensure its performance. Therefore, the quality of grinding is crucial to the normal operation of the motor, and directly affects the service life of the motor. The scraping and grinding quality is poor, and it is easy to cause the bearing bush to develop from partial adhesion damage to most adhesion damage in a very short period of time during the motor test run, until the bearing bush cannot be used due to shaft burning. Therefore, when scraping and grinding the bearing shells, they are all operated by experienced bench workers.
| 2023 March the Fourth Week Epen Technical Knowledge: Characteristics of sliding bearing materials
The effective operation or failure of sliding bearings is closely related to the selection of load, speed, lubricating oil, and bearing geometric parameters. However, the reasonable selection of sliding bearing materials will play a decisive role in the exertion of sliding bearing capabilities. Damage to antifriction materials for sliding bearings can cause damage to related parts, so sliding bearing materials should have good wear resistance, corrosion resistance, fatigue resistance, and pollution resistance.
| 2023 March the Third Week Epen Technical Knowledge: Wear failure analysis of hoist sliding bearing
The continuous progress of science and technology has promoted the emergence and gradual application of a new type of mine hoist with rolling bearings. However, sliding bearings are still widely used in mine construction due to their more stable service life and higher transmission accuracy. However, the configuration of the sliding bearing hoist is relatively difficult, and the maintenance conditions are relatively high. Among them, the wear and failure of the sliding bearing of the hoist is one of the problems that should be focused on in coal mining. Therefore, the paper analyzes the wear failure of the elevator sliding bearing, and puts forward corresponding adjustment measures, in order to provide effective reference for the use efficiency of the elevator sliding bearing type.

Sliding bearing, which works under sliding friction. The sliding bearing works stably, reliably and noiseless. Under the condition of liquid lubrication, the sliding surface is separated by the lubricating oil without direct contact, which can also greatly reduce the friction loss and surface wear. The oil film also has a certain vibration absorption capacity, but the starting friction resistance is large.

The guide is a device to prevent the deflection of the lift car and counterweight when they move up and down to ensure the smooth operation of the elevator. The guides are installed on the car and counterweight device, and the car guides are installed on the top beam of the car and the bottom of the car. A total of four sets of counterweight guides are installed on the top and bottom of the counterweight frame. During operation, the concave groove (or roller) of the guide is matched with the convex working surface of the guide rail, so that the car and counterweight device only move up and down along the working surface of the guide rail to prevent the car and counterweight device from deflecting or swinging during operation.
