Thrust cylindrical roller bearing is a common mechanical transmission element, mainly used to support and transmit axial load. It has the advantages of simple structure, large bearing capacity and long service life, and is widely used in various mechanical equipment. This article will introduce the structure, working principle, application and maintenance of thrust cylindrical roller bearings.

1. Structure

Thrust cylindrical roller bearings consist of inner and outer rings and rolling elements. The raceway between the inner and outer rings is filled with cylindrical rollers. The contact surface between the roller and the raceway is linear, the axial load acts on the roller, and the roller transfers the load to the outer ring of the bearing through rolling, so as to realize axial support and transmission.

Thrust cylindrical roller bearings are generally divided into two types: one-way and two-way. One-way thrust cylindrical roller bearings have one-way load capacity and can only bear axial load in one direction. The two-way thrust cylindrical roller bearing can bear the axial load in two directions.

2. Working principle

The working principle of thrust cylindrical roller bearings can be explained by rolling friction theory. When an axial load acts on the rollers, the rollers move in the raceways by rolling. Due to the large number of contact points between the roller and the raceway surface, the rolling friction force is relatively small, thereby reducing the friction loss and wear of the bearing and prolonging the service life.

3. Application

Thrust cylindrical roller bearings are widely used in various mechanical equipment such as machine tools, motors, automobiles, ships, and aircraft. On machine tools, thrust cylindrical roller bearings can be used to support the axial force of the main shaft; on automobiles, thrust cylindrical roller bearings can be used to support the axial load of gearboxes and rear axles. In addition, thrust cylindrical roller bearings can also be used in various pumps, compressors, generators and other equipment.

4. Maintenance

The maintenance of thrust cylindrical roller bearings mainly includes cleaning, lubrication, inspection and replacement. When cleaning, the dirt and grease in the bearing should be cleaned with a specific cleaning fluid. When lubricating, appropriate grease or oil should be selected for lubrication. During the inspection, attention should be paid to whether the axial clearance and axial bearing capacity of the bearing are normal. If the bearing is abnormal, it should be replaced immediately.

In conclusion, thrust cylindrical roller bearing is an important mechanical transmission element with multiple advantages and wide application scenarios. Understanding its structure, working principle, application and maintenance is of great significance for the correct use and maintenance of thrust cylindrical roller bearings.

What are the symptoms of a broken clutch release bearing?

If the release bearing is damaged, it may happen that the clutch plate cannot be completely separated after the clutch pedal is depressed, resulting in difficulty in shifting gears. If the bearing is damaged, it will affect the normal operation of the engine, so the bearing must be replaced immediately after it is damaged. The release bearing is connected to the clutch pedal. When the clutch pedal is depressed, the release bearing will press against the diaphragm spring on the pressure plate. At this time, the diaphragm spring will tilt, so that the clutch plate is separated, and the connection between the engine and the gearbox is disconnected.

What are the types of deep groove ball bearings?

Deep groove ball bearings are mainly used to bear radial loads, but they are also commonly used to bear combined radial and axial loads. Especially when the rotating speed of mechanical equipment is very high, it is not suitable to use thrust bearings. This bearing can be used to bear two-way pure axial load, and it does not need maintenance during operation. It is a kind of bearing with low price and wide application.

Deep groove ball bearing installation method

Deep groove ball bearing installation method 1: press fit: the inner ring of the bearing and the shaft are tightly fitted, and the outer ring and the housing hole are loosely fitted, the bearing can be pressed on the shaft first with a press, and then the shaft together with the bearing Put them into the bearing seat hole together. When pressing, place a soft metal assembly sleeve (copper or mild steel) on the end face of the bearing inner ring. The outer ring of the bearing is tightly fitted with the bearing seat hole, and the inner ring and the shaft are When the fit is loose, the bearing can be pressed into the bearing seat hole first. At this time, the outer diameter of the matching tube should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, install the inner ring and The outer ring should be pressed into the shaft and the seat hole at the same time, and the structure of the assembly sleeve should be able to press the end faces of the inner ring and the outer ring of the bearing at the same time.

What is a spherical roller bearing?

Spherical roller bearings have double-row rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easy to be affected by the angle error or shaft bending of the shaft and the bearing housing, and is suitable for installation errors or shaft deflection that cause angle errors. In addition to bearing radial loads, the bearing can also bear axial loads acting in both directions.

What is self-aligning ball bearing?

The self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of the two raceways and the outer ring with spherical raceways. The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and shell are deflected, it can be adjusted automatically without increasing the burden on the bearing. Spherical roller bearings can bear radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads and impact loads. The inner diameter of the inner ring is a bearing with a tapered hole, which can be directly installed. Or use an adapter sleeve or a dismounting cylinder to install on a cylindrical shaft. The cage uses steel stamping cage, polyamide forming cage and copper alloy car cage.

How to identify true and false self-aligning ball bearings

Each bearing product will have its brand name, label, etc. printed on the bearing product body. Although the font is very small, the products produced by regular manufacturers are printed with steel stamping technology, and the characters are embossed before heat treatment, so although the font is small, it is deeply concave and very clear. Under normal circumstances, the fonts of counterfeit products are not only blurred, but due to the rough printing technology, the fonts float on the surface, and some of them can be easily wiped off by hand or have serious hand marks.
