Bearing structure

Deep groove ball bearing is simple in structure and easy to achieve higher manufacturing accuracy compared with other types. Therefore, it is easy to be produced in series in large quantities with lower manufacturing cost and extremely common in use.Deep groove ball bearing in addition to the basic type, there are a variety of variant structure, such as: deep groove ball bearing with dust cover, with rubber seal ring deep groove ball bearing, deep groove ball bearing with stop groove, deep groove ball bearing with large load capacity with ball notch, double row deep groove ball bearing.

Bearing type

Deep groove ball bearings are mainly used to bear radial loads, but they are also commonly used to bear radial and axial combined loads.In particular, the thrust bearing can be used to bear two-way pure axial load when the speed of mechanical equipment is very high and it is not suitable for the use of thrust bearing.Deep groove ball bearing type: deep groove ball bearing (60000 type);Deep groove ball bearing with stop groove in outer ring (60000N type);Deep groove ball bearing with dust cover on one side and stop groove on the other side (60000-zn type);Deep groove ball bearing with dust cover on both sides and stop groove on the outer ring (60000-2zn type);Deep groove ball bearing with dust cover on one side (type 60000Z);Deep groove ball bearing with dust cover on both sides (60000-2z type);Deep groove ball bearing with sealing ring on one side (60,000-ls type, 60,000-rz type);Deep groove ball bearings with sealing rings on both sides (60,000-2ls type, 60,000-2rz type);Deep groove ball bearing with outer flange (F60000 type);Deep groove ball bearing with outer flange of one side with dust cover (f60000-z type);There are 11 kinds of deep groove ball bearings (f60000-2z type) with outer flange and dust cover on both sides.[2]

According to the size of deep groove ball bearing can be divided into:

(1) miniature bearing -- bearing with nominal outer 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 ranging from 60-115mm;

(4) medium and large bearings -- bearings with nominal outer diameter range of 120-190mm

(5) large bearing -- bearing with nominal outer diameter range of 200-430mm;

(6) extra-large bearing -- bearing with nominal outer diameter of more than 440mm.

Processing the form

The processing forms of deep groove ball bearing parts are as follows:

1, multi-process processing: general bearing production needs 20 ~ 40 processes, more than 70.

2, forming processing: the working surface of bearing parts are rotary forming surface, suitable for processing with forming method.

3, precision machining: most of the surface of bearing parts to go through grinding processing, grinding size and geometric accuracy are in the unit of mum.

Application editing

Deep groove ball bearing can be used for transmission, instrumentation, electrical machinery, household appliances, internal combustion engines, vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo ball and so on

Installation method

Installation method of deep groove ball bearing:Bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, available press the bearing pressure equipment in the shaft first, then the shaft together with the bearing load bearing hole, when pressed on the bearing inner 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, the 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 timeThe construction of the assembly sleeve shall be able to fasten the end faces of the inner and outer rings of the bearing at the same time.

Installation method of deep groove ball bearingBy heating bearing or bearing, using thermal expansion will fit into a loose fit installation method. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearings, 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 heating the hot charging method of the bearing, can avoid the mating surface scratch.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.
