Deep groove ball bearing is the most common type of rolling bearing. The base 
Deep groove ball bearingThis type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cage. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is divided into two types: sealed and open. Open type means that the bearing does not have a sealed structure. Dust seal cover material for steel plate stamping, only play a simple way to prevent dust into the bearing raceway. The oil-proof type is the contact type oil seal, which can effectively prevent the grease overflow in the bearing.
Single row deep groove ball bearing type code is 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the most common production, the most widely used type of bearings.
Deep groove ball bearing is the most representative rolling bearing, which is widely used. Suitable for high or even very high speed operation, and very durable, without frequent maintenance. Such bearings have low friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy. It is widely used in precision instrument, low noise motor, automobile, motorcycle and general machinery industries. It is the most widely used type of bearings in the machinery industry. Mainly bear the radial load, also can bear a certain amount of axial load.
The axial bearing capacity increases when a large radial clearance is selected, and the contact Angle is zero when it is subjected to pure radial force. With axial forces, the contact Angle is greater than zero. A rammed - wave cage is usually used, a car - made solid cage, and sometimes a nylon cage.
After the deep groove ball bearing is mounted on the shaft, it can limit the axial displacement of the shaft or housing in both directions within the axial clearance range of the bearing, so it can be positioned axially in both directions. In addition, the bearing also has a certain ability to adjust the center, when relative to the shell hole tilt 2 '~10', it can still work normally, but has a certain impact on the bearing life. Deep groove ball bearing retainers are mostly steel plate ramming wave retainers, large bearings are mostly made of metal body retainers.
Deep groove ball bearings are the most commonly used rolling bearings. It is simple in structure and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearing and can bear combined radial and axial load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear the pure axial load. Other types with the same dimensions as deep groove ball bearingsbearingCompared, this kind of bearing friction coefficient is small, the limit speed is high. However, it is not resistant to impact and is not suitable to bear heavy loads.
Deep groove ball bearing structure is simple, compared with other types of easy to achieve higher manufacturing accuracy, so it is easy to into a series of mass production, manufacturing cost is low, use is very common. Deep groove ball bearing in addition to the basic type, there are a variety of variant structures, such as: deep groove ball bearing with dust cover, deep groove ball bearing with rubber seal ring, deep groove ball bearing with stop groove, deep groove ball bearing with large load capacity with ball notch,Double row deep groove ball bearings。
1. Single row deep groove ball bearing
2. Single row deep groove ball bearing with dust cover
3. Single row deep groove ball bearing with dust cover and sealing ring
4. Single row deep groove ball bearing with stop groove and stop ring on the outer ring
5. Deep groove ball bearing with ball gap
6. Double row deep groove ball bearings
According to the size of deep groove ball bearing, it can be divided into:
(1) miniature bearings -- bearings with nominal outside diameter of less than 26mm;
(2) small bearings -- bearings with nominal outer diameter ranging from 28-55mm;
(3) small and medium-sized bearings -- bearings with nominal outer diameter of 60-115mm;
(4) medium and large bearings -- bearings whose nominal outer diameter range is 120-190mm
(5) large bearings -- bearings whose nominal outer diameter range is 200-430mm;
(6) oversize bearings -- bearings with nominal outside diameter of more than 440mm.
Deep groove ball bearings can be used for gearbox, instrument, electrical machinery, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller type roller skates, yo-yo, etc
Deep groove ball bearing installation method 1: pressing fit: bearing inner ring and shaft to make tight fit, outer ring and bearing seat hole is more loose fit, can be used to press the bearing first installed on the shaft, and then the shaft and bearing together into the bearing seat hole, pressing inbearingInner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel), bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same time assembling casing structure should be able to at the same time, so the bearing inner ring and outer ring end face.
Deep groove ball bearing installation method 2: heating cooperates: through heating bearing or bearing seat, by using thermal expansion will fit into a loose fit method of installation. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. Bearing outer ring and light metal bearing seat tight fit, by heatingbearingThe hot loading method can avoid the abrasions on the mating surface. Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
The standard deep groove ball bearing is of ordinary grade, all in accordance with GB307.1.
The standard type deep groove ball bearing has C2, standard (CN), C3, C4 and C5 internal clearance, all in accordance with GB4604.
Deep groove ball bearings usually use steel plate stamping cage or brass body cage. When the outside diameter is less than 400 mm, use steel plate stamping cage without the rear code, when the outside diameter is more than 400 mm, brass body cage without the rear code.
The processing forms of deep groove ball bearing parts are as follows:
1, multi-process processing: general bearing production needs 20 to 40 processes, more than 70.
2. Forming processing: the working surface of bearing parts is rotary forming surface, which is suitable for shaping processing.
3. Precision machining: most of the surfaces of bearing parts need to be ground. The grinding size and geometric precision are based on the unit of David.
Deep groove ball bearing, the operation of the bearing load is too small, will cause the ball and raceway between the occurrence of sliding, become the cause of abrasions. Especially the ball andcageHeavy - duty deep groove ball bearings have this tendency. It is expected that there will be too small load in the use of the situation, in the selection of bearings should be timely contact with the relevant personnel!
In many cases, the bearing will rust phenomenon, leading to the corrosion of the bearing there are many reasons, the most common in our daily life mainly have the following factors.
1) due to the poor sealing device, it is invaded by moisture, dirt, etc.;
2) the bearing is not used for a long time, which exceeds the rust prevention period and lacks maintenance.
3) the roughness of the metal surface is large;
4) if the bearing is in contact with corroded chemical medium, the bearing is not clean and has dirt attached to its surface, or if the bearing is contacted with sweaty hands, the bearing is not packaged or installed in time after cleaning, and is exposed to air for a long time, which is affected by air moisture and contamination;
5) environmental temperature and humidity and contact with various environmental media; Rust inhibitor failure or quality is not up to standard.
